Silence is unnatural to a man. He begins life with a cry and 1 it in stillness. In between he does all he can to make a 2 in the world, and he 3 silence more than anything else. Even his conversation is an attempt to prevent a fearful 4 .If he is introduced to another person,and a number of pauses occur in the conversation, he will regard himself as a 5 , a worthless person, and will be full of envy of the most empty-headed chatterbox (话多的人). He knows that ninety-nine percent of human 6 means no more than the buzz of a fly, but he is anxious to join in the buzz and to 7 that he is a man and not a waxwork (蜡像).
The 8 of conversation is not, for the most part, to communicate ideas; it is to 9 the buzzing sound. There are, it must be 10 , different qualities of buzzes; there is even a buzz that is as annoying as the continuous noise made by a mosquito (蚊子). 11 at a dinner party one would rather be a mosquito than a quiet person. Most buzzes, 12 ,are pleasant to the ear, and some of them are pleasant even to the mind. He would be a ( n) 13 man if he waited until he had a wise 14 to take part in the buzz with his neighbors .
Those who 15 to pick up the weather as a conversational opening seem to me not to know the reason why human beings wish to talk. Very few human beings join in a conversation 16 learning anything new. Some of them are 17 if they are merely allowed to go on making a noise into other people’s 18 ,though they have 19 to tell them except that they have seen two or three new plays or that they had food in a Swiss hotel. At the end of an evening during which they have said nothing meaningful for a long time, they just prove themselves to be 20 conversationalists.

Have you ever seen a car without a driver? It sounds crazy, but these computerdriven cars will soon be __1__ roads near you. Companies like Google and Tesla have been designing and __2__ these cars.
So how do they work? The cars have sensors all around which can __3__ other cars and __4__ on the road. Road signs are read by __5__, and satellite navigation systems are used so the car knows how to get to your __6__. All you have to do is type in the address! Finally, a central computer system takes in all the __7__ it receives from the sensors and cameras and processes this to work out when to __8__, brake and steer on the road.
__9__ like your idea of heaven? Sitting back, looking out __10__ the windows or reading a book while “driving” would be __11__ with this new technology. You wouldn't have to worry about remembering __12__ to where you're going. In addition, computers would also drive more __13__ than people—they don't get distracted by music or friends, and they have quicker reaction time in case of a(n) __14__.
However, there are many __15__ of driverless cars. I personally find driving fun—I'd miss being behind the wheel myself. There would also be many __16__ decisions to be made—should children, or drunk people, be allowed in a driverless car by themselves? __17__, many people would be put out of work with the __18__ of driverless cars.
I'm not __19__ I'd want a driverless car—but it's only a matter of time __20__ they'll become more affordable and commonplace on our roads.

A researcher who __12__ the sound of the mating call of a certain fish, on the other hand, can know just by listening __13__ that fish reproduces.
“If you know what a fish sound is, then you have a really __14__ tool,” researcher Rountree says. “Once you know a number of __15__ sounds, you can do a census based on the sounds.”
Because so few studies have been done, indepth studies of fish sounds __16__ the promise of many new discoveries. “__17__ makes my day,” he says. “This is a huge area we don't know anything about. It just __18__ out to me, and I've got to go and find out. Anyone who's interested can get involved __19__.

(2019·福建福州龙泰一中高三自考)In many movies and books set in the future, robots can fly spaceships, work as maids or butlers, and even act as police officers.
The 5foot, 300pound “K5” robots are part of a trial program to __1__ a machine's ability to perform the duties of a safety officer. The robots are __2__ with HD security cameras, sensors, alarms, etc. In addition, they have an artificial intelligence system that will __3__ a human security guard if the robots notice anything unusual.
The robots' __4__ can also analyze faces and read license plates. The robots can check whether a plate __5__ belongs to a stolen vehicle. Plus, the robots' onboard cameras are able to __6__ good quality video in lowlight conditions.
The K5 is able to __7__ through its environment by using GPS as well as an internal navigation system. Each time the K5 is brought to a __8__ place, a human uses a wireless controller to __9__ the robot around the area. This helps the K5 “learn” about its __10__.
“You give it a base map and then it starts __11__ from that,” says Stacy Stephens, the cofounder of Knightscope.
Unlike humans, the K5 security guards don't need __12__—they can work almost 24 hours a day. The robots run on rechargeable batteries, and a single __13__ lasts 24 hours. If a robot notices that its battery is getting __14__, it will return to a charging port and plug itself __15__. It takes only 15-20 minutes for it to fully recharge, so the K5s are not out of __16__ for long.
The robots don't carry weapons, but it's still not a good idea to __17__ with them. An earpiercing alarm will sound __18__ the K5 is detained for more than a few minutes.
“Because they are designed to do the kind of work a human security guard would __19__ do, the robots take away the repetitive and sometimes __20__ guard work,” Stephens explains.

In case an astronaut floats away, he/she can use the controller __7__ to the front of the spacesuit to return to the spacecraft. The only __8__ is that SAFER is operated by hand, which means it is of no use if the astronaut becomes __9__, or gets injured.
To __10__ the problem, the Charles Stark Draper Laboratory is working with NASA to create an application to start SAFER __11__. Dubbed “take me home”, it involves fitting spacesuits with sensors that __12__ the astronaut's movement, acceleration, and relative position to a stationary spacecraft. Since there is no GPS in deep __13__, the team has come up with two clever ways to determine the astronaut's exact __14__.

With his leg lame and his teeth uneven(参差不齐的), the boy almost thought of himself as the most unfortunate child in the world. 21 did he play with his classmates, and when asked to answer questions, he always 22 his head without a word.
One spring, his father brought home some young trees. 23 of his children would plant a young tree and he promised, “Whoever 24 his young tree best shall get a favorite gift.” The boy certainly wanted to get his father’s gift. 25 seeing his brothers and sisters watering the trees, an idea 26 him: he hoped the tree he planted would die soon. So watering it once or twice, he never 27 it.
Several days later, when the little boy went to see his tree again, he was 28 to find that not only did it not die, but also grew so many fresh 29 . Compared with those of his brothers and sisters, his appeared greener. His father kept his 30 , bought the little boy one of his favorite 31 and said that from the tree he planted, he would surely become an outstanding botanist(植物学家)when he grew up.
From then on, the little boy slowly became 32 and confident. One night, he suddenly 33 that his biology teacher once said that plants 34 grow at night. Why not go to see his tree?
When he came to the courtyard, he found his father was working near his tree! Instantly he 35 : his father had been secretly 36 his small tree! He returned to his room, with tears 37 in his eyes.
Decades passed. The little boy didn’t become a botanist. 38 , he became the U.S. president. His name was Franklin Roosevelt.

Research shows that when we are absorbed in an activity,even minor distractions(分心)can have a huge effect. According to a study,regaining our 36 drive following an interruption can take about 20 minutes.
Multitasking(多任务),as many studies have shown, is a myth(谬论).A more accurate 37 of what happens when we tell ourselves we are multitasking is that we’re rapidly 38 between activities,sucking our mental energy. And the 39 can be surprisingly serious. An experiment found that we lose as many as 10 IQ points when we allow our work to be 40 by distractions like emails and text messages.
The 41 is that multitasking is enjoyable. It's fun to satisfy your curiosity. Who knows what that next email or text message holds 42 ?Finding out provides immediate satisfaction, 43 ,resisting distractions and staying on task requires 44 and mental effort.
So, what are we to do?
Our strategy is to change the 45 to move temptation further away: shut down your email program or 46 your phone. It's a lot easier to stay on task when you’re not 47 fighting off mental desires.
The alternative,which most of us consider common,is 48 to dieting in a bakery. We all need the willpower to resist the temptations,but doing so comes with 49 costs to our limited supply of willpower.
Another worthwhile 50 is to collect similar activities together,keeping transition(转换)time to a 51 point. Instead of spreading phone calls,meetings and emails throughout your day, try 52 related tasks so that there are fewer transitions.
In some jobs,multitasking is 53 . Some of us truly do need to stay 54 to our clients,colleagues and managers. So it’s worth noting that limiting disruptions is the only solution.
Remember,the more you do to minimize task-switching over the course of the day,the more ability you'll have for activities that actually 55 . Even small changes can make a big difference.

Better Solar Energy Systems: More Heat, More Light
Solar photovoltaic thermal energy systems (太阳能光伏热能系统), or PVTs, produce both heat and electricity, but until now they haven’t been very good at the heat-producing part __51__ a stand-alone (单机的) solar thermal collector. That’s because they operate at low temperatures to cool crystalline silicon solar cells (晶体硅太阳能电池), which lets the silicon produce more electricity but isn’t a very __52__ way to gather heat.
That’s a problem of economics. A solar-electric system is run at a comparatively lower __53__, while good solar hot-water systems can harvest much more energy. And it’s also a space problem: photovoltaic (光伏的) cells can __54__ all the space on the roof, leaving little room for thermal applications.
In a pair of studies, Joshua Pearce, an associate professor of materials science and engineering, has designed a __55__ in the form of a better PVT made with a different kind of silicon. His research partners are Kunal Girotra from Thin Silicon in California and Michael Pathak and Stephen Harrison from Queen’s University, Canada.
Most solar panels (电池板) are made with crystalline silicon, but you can also make solar cells out of amorphous silicon (非晶体硅), __56__ known as thin-film silicon. They don’t create as much electricity, but they are lighter, flexible, and cheaper. Because they __57__ much less silicon, they are more environmental friendly and have a greener footprint. __58__, thin-film silicon solar cells can be easily damaged and are breakable.
“That means that, when you expose them to light, their efficiency __59__ ---- pretty much the worst possible effect for a solar cell,” Pearce explains, which is one of the reasons thin-film solar panels make up only a small __60__ of the market.
However, Pearce and his team eventually found a way to improve the __61__ of solar panels by uniting thin-film silicon into a whole in a new type of PVT after many experiments. You don’t have to cool down thin-film silicon to make it work and improve its working efficiency. __62__, Pearce’s group discovered that by heating it to solar-thermal operating __63__, near the boiling point of water, they could make thicker cells that largely overcame the __64__ effect. When they applied the thin-film silicon directly to a solar thermal energy collector, they also found that by baking the solar cell once a day, they __65__ the solar cell’s electrical efficiency by over 10 percent.

The phone rang. “I’d like to drop off a bank draft (汇票),” said a man’s voice in a robotic tone. “Will you be __51__ in the next 20 minutes?” I said yes.
The call wasn’t a __52__. Twelve years ago, I was diagnosed (诊断) with a disorder that causes my skin and internal organs (内脏器官) to __53__. Basically, I’m turning to stone. I’ve been able to buy some time with expensive medicine, but the disease has__54__, and my doctors are working hard to avoid lung fibrosis (纤维症), which leads to heart failure.
Last year, I learned about an experimental procedure in Chicago, with an 80 percent success rate, that can _55__ my stem cells, purify them and put them back into my body to __56__ a clean, new immune system (免疫系统). My four kids started fund raising in June to __57__, in part, the $125,000 cost of the treatment. I assumed the __58__, who phoned on July 3, had read about our website in the local paper and wanted to give a donation.
Ten minutes later, a middle-aged man __59__ at my door. Opening the door, I found he was tall and wore a white golfer’s cap, big sunglasses and a grey spring coat. He handed me a long white __60__. I said, “God bless you.” He didn’t say a word. He just smiled and walked away. I closed the door and opened the envelope. The number on the draft made no __61__— I was sure I was reading it wrong: $128,000. I fell down, and the crash brought my mom running. When she got there, I shouted, “Oh, my God, oh, my God.” We __62__ each other, crying and screaming.
Who was he? Friends ask if I think he was an actor or a hockey player. I didn’t get the feeling that he was __63__. But it’s not important. __64__, here’s what __65__: In January, I’ll be in Chicago for the three-month operation. Whoever that man was, he saved my life.

Walking alone on a remote beach in southwest Florida, I was surprised to hear splashes coming from the water. As I walked in the 41 of the sounds, I saw a manatee(海牛)show its head out of the water, 42 a great snuffling(带鼻音的)breath. It seemed that it was in 43 and trying to get out of it.
I'd never seen a 44 like this before. I wanted to 45 , but there was no one else on the beach. So I went into the shallow water and went toward the animal. I came 46 enough to make out the manatee. Then, a second manatee, much smaller, appeared beside it. 47 , the manatees were also moving toward me. Soon I was 48 by several manatees. I could clearly see the larger manatee 49 the little one up with her flipper(鳍状肢)and pushed it to the 50 beside me.
As the two slipped underwater, two other manatees moved up from behind, one on either side, 51 gently against my body as they swam past. They circled and 52 the action, this time 53 by the mother and her baby. I held my hand out touching their back as they passed me. Since they obviously enjoyed touching me, I began 54 each of them as they swam by.
I stood there enjoying the scene, 55 to move, until finally the rising tide forced me back to the shore. Later I knew exactly what took place that morning. The manatees 56 me in their celebration of a birth and I was welcome to meet the 57 member of their family.
During that unexpected scene, I felt more involved in the rhythms of 58 on our earth than ever. Each year, I head for that 59 for a quiet little birthday picnic on the shore. After all, you never know who might 60 up for your party.

A terrible fever made Anne Sullivan nearly lose her eyesight in her childhood,and the doctors said she was a hopelessly mad girl. She had been 41 in the basement of a mental hospital(精神病医院) in Boston.Sometimes,little Annie 42 hit anyone who came near to her. She ignored everyone who appeared in front of her most of the time.
However,an old nurse 43 that little Annie had hope. She went to 44 little Annie every day. The child ignored her in most cases,but the old nurse 45 stopped seeing her every day in the basement. The 46 lady left cookies for little Annie and spoke words full of encouragement to her. She believed that as long as she showed 47 ,little Annie could get better.
Finally,the doctors noticed the 48 in little Annie. They moved her upstairs and her condition continued 49 . Then her last day there came,and the child who seemed to be “ 50 ” went out of the locked door of the mental hospital.
After she grew up,Anne Sullivan hoped to 51 others,just as the kind old nurse helped her. She became the 52 of Helen Keller.She 53 her,trained her strictly and worked with her 54 she lit the candle that brought 55 to the whole world. Anne Sullivan 56 a miracle(奇迹) in the life of Helen Keller. But first it was a kind nurse who had full 57 in little Annie that turned a(n) 58 child into a great teacher.
If there had been no Anne Sullivan,the name of Helen Keller would not be 59 . But if there hadn’t been a 60 who kept showing love,Anne Sullivan wouldn’t be known to the world,either.

What is intelligence anyway? When I was in the army I 16 an intelligence test that all soldiers took, and, against 17 of 100, scored 160.
I had an auto-repair man once, who, on these intelligence tests, could not 18 have scored more than 80. 19 , when anything went wrong with my car I hurried to him —and he always 20 it.
Well, then, suppose my auto-repair man 21 questions for some intelligence tests. By every one of them I'd prove myself 22 . In a world where I have to work with my 23 , I'd do poorly.
Consider my auto-repair man 24 . He had a habit of telling 25 . One time he said, “Doc, a deaf-and-dumb (聋哑) man 26 some nails. Having entered a store, he put two fingers together on the counter and made 27 movements with the other hand. The clerk brought him a hammer. He 28 his head and pointed to the two fingers he was hammering. The clerk 29 him some nails. He picked out the right size and left. Well, Doc, the 30 man who came in was blind. He wanted scissors. 31 do you suppose he asked for them?” I lifted my right hand and made scissoring movements with my first two fingers. He burst out laughing and said, “Why, you fool, he used his 32 and asked for them. I've been 33 that on all my customers today, but I knew 34 I'd catch you.” “Why is that?” I asked. “Because you are so goddamned educated. Doc. I knew you couldn't be very 35 .”
And I have an uneasy feeling he had something there.

Attitude with action is everything. That’s what I’ve 41 from a simple person at our office gym.
Last month our city conducted a fitness center---“FitnessOne”. And we had a trainer there, who had a bad 42 to his work and us. He used to come down to our office every evening but he was least 43 about who was coming in and what people were doing inside. He only talked about the money he earned by 44 people individually in another fitness center where he 45 in the mornings. He never guided us. 46 , he would not even 47 properly when any of us asked about the way of doing exercise. 48 , at the end of last month he was 49 and we got a new trainer.
The gentleman was Bala. He would quietly come in and do 50 for the first few days except looking at the register, 51 who came regularly to the gym. Slowly, he became 52 with the users and started to correct their mistakes while exercising. And people built up 53 in him. Yesterday, he called me to watch some specific exercises. 54 his interim(昨时的)period of one month was coming to a(n) 55 , he wanted me to learn them properly before he left us. we’ve 56 FitnessOne to appoint Bala as a 57 trainer and now we are waiting for their reply.
Bala could have taken his role as a trainer like our 58 guy since he stayed here only for a month. But he 59 to take it seriously and sincerely. His positive attitude along with his 60 gained our trust and support. I think this is his great achievement.

Expressions on the face carry meanings,which depends on situations and relationships.For instance,in American culture the smile is typically an expression of (41) .Yet it has other functions.A smile may (42) love,politeness,or(43) true feeling.It is also a source of confusion(混乱) across (44) .(45) ,many people in Russia (46) smiling at strangers in public to be unusual or even suspicious(怀疑).Yet many Americans (47) freely at strangers in public places.Some Russians believe that Americans smile in the wrong (48) ; some Americans believe that Russians don't smile enough.In Southeast Asian cultures,a smile is frequently used to cover emotional pain or mental difficulty,discomfort or anxiety.
Our faces make our emotions and attitudes known,(49) we should not try to"read"people from another culture (50) we would"read"someone from our own culture.The degree of facial expressiveness one shows changes (51) persons and cultures.The fact that members of one culture do not (52 their emotions as openly as members of(53) does not mean (54) they do not(55) emotions.Rather,their cultures (56) them from expressing their emotion and attitudes freely.
