As you grow rapidly through your teenage years, you will experience a lot of changes. The changes may seem difficult and they may seem to happen quickly. Don't panic! You will deal successfully with them! You are a young adult now!

With more responsibility, you will find more freedom to make your own choices. This is a time to be well informed about your choices so that you can make healthy balanced decisions that will help shape your future. You may already know your career path or you may have no idea at all what you want to do. Both situations are fine! Work hard and the right opportunity will present itself to you.

Young adulthood means greater freedom and more choices. You will probably want to be independent. But try not to shut your family out of your life. You should learn to think of others even though you are old enough to look after yourself. Your family have been with you since you came into this world.

It is also perfectly natural in this time for you to spend more time with your friends than your family. Choose your friends wisely. A true friend will stand by you no matter what happens.

This period is part of the life cycle. There are some_people who will be with you throughout life's journey and there will be some people with whom you part and go separate ways. Leaving school can be hard. The reality is that you may not ever see all of your classmates again.

You are a young adult. It is your life. No one can live it for you. The choices that you make from now on will be your choices. So making the right choices will be important to you. Life is for living. Enjoy your life wisely!

You can never be too sure these days in the United States of your neighbors or even your customers! Try to keep a low profile (姿态) in your neighborhood: Don't announce to everyone that you are running a home business with thousands of dollars worth of equipment. As much as possible, do not invite clients (客户) or visitors to your home. In fact, I know of some home­based entrepreneurs (企业家) who would rather meet their clients in a neutral ground, e．g. the client's office or even Starbucks.

There are other ways to keep burglars away from your house.

•Keep lights on around your house in the evenings. Light is a natural fright for burglars.

•Invest in a security alarm, particularly if your house is located at a remote spot. Security systems can often bring down the cost of your homeowner's premium (保险费)．

•Make sure that all windows and doors are locked and the security alarm turned on before you sleep at night or go out of the house. Avoid keeping house keys in obvious places, such as under the lamp or on top of the doorframe.

•Adding an additional lock will provide extra security when you are home. The dead­lock, sometimes called an “exit only deadbolt” is a deadbolt that does not have an external (外部的) key. It is clearly visible on the door from the outside, but cannot be broken into without destroying the door, frame or lock itself. While this security won't help directly when you aren't home,  the visibility may discourage an intruder from trying the door.

•Your door itself should be made of strong materials, such as one­inch thick solid hardwood or heavy metal.

25．The advice given by the writer in the passage focuses on ________.

A．how to make your house safe from burglars

B．what to do when your house is broken into

C．how to improve social security in the United States

26．Some home­based entrepreneurs do not invite clients to their home ________.

A．to enjoy convenience outside their home

B．for the safety of their property

27．All the following are part of the writer's advice except that the homeowner ________.

A．buy a security alarm and turn it on in the evening

B．fix an extra lock on the door from inside

C．have the doors made of solid hardwood or heavy metal

D．keep lights on in all rooms to threaten burglars

28．What does the underlined word “intruder” most probably mean in the passage?

A．Someone who is invited for a visit.

B．Someone who illegally enters the home.

C．Someone who pays regular visits to the home.

D．Someone who tries to destroy the lock.

Some people are pessimistic (悲观的) when they think about the future. They say that, a hundred years from now, we will have used most of the earth's resources. We will have polluted our seas badly, and be unable to eat fish from them. We will have made the air so dirty that we will need to wear masks. The world's population will have doubled, and we will have used all the countryside for housing; there will be no farmland left.

Other people believe that Man adapts very easily. They have a different idea of the future. How, in their views, will people be living in a hundred years' time?

One architect believes that Man will move off the land. He suggests that the city of the future will be a huge, pyramid­shaped building, which will be floating on the surface of the sea. About 5,000 families will be living there, and the building will contain shops and schools as well as homes. By living on the sea, we will give the farmers more land to grow crops.

As for oil, people will no longer need it: we will be heating our homes with power from the sun. And we will not be short of minerals, because there are plenty under our oceans. At the moment, we do not have the technology to get them out. But, in a hundred years' time, the optimists say, the new sea cities will be using these resources.

What will be in the shops in the year 3000? What will people be wearing? How will people be traveling?

Scientists who make predictions about the future suggest that, by the year 3000, shops will no longer exist. Computers will have replaces them; and people will order goods from home.

People will be wearing very light, thin clothes. By this time, scientists will have invented a fabric that keeps us cool in hot weather and warm in cold weather.

As for travel, the experts say that most people will be using public transport. Electric cars will be traveling through the streets day and night. Anybody will be able to stop one and use it.

An interesting picture. Unfortunately, we will not be there to see if these predictions come true.

A．the seas and oceans will be full of houses

Today is National Bike­to­Work Day. And on New York City's jammed streets, people are cycling on hundreds of miles of new bike lanes. But New York's widespread efforts to make streets safer for bikes have also left some locals complaining about the loss of parking spots and lanes for cars.

When the weather is good, Aaron Naparstek likes to pedal (用踏板踩) his two young kids to school on a special Dutch­made bicycle. Naparstek supports the new lane.

Aaron: The bike lane on Prospect Park West is really introducing a lot of new people to the idea that it's possible to use a bike in New York City for transportation or to travel around. This is what 21st century New York City looks like.

Prospect Park West is still a one­way road, but where it used to have three lanes of car traffic, now it has two, plus a protected bike lane. Supporters say that makes the road safer for everyone, including pedestrians, by slowing down cars and taking bikes off the sidewalk. But some longtime residents disagree. Lois Carswell is president of a group called Seniors for Safety. She says the two­way bike lane is dangerous to older residents who are used to one­way traffic.

Lois: We wanted a lane—the right kind of lane that would keep everybody safe, that would keep the bikers safe. But we want it to be done the right way. And it has not been done the right way.

Craig Palmer builds bars and restaurants in Manhattan. I was interviewing him for a different story when he brought up the bike lanes all on his own.

Craig: I think the biggest problem is that Bloomberg put all these bike lanes in. You took what used to be a full street and you're shrinking it.

Then there are the Hasidic Jews in Williamsburg, Brooklyn, who forced the city to remove a bike lane through their neighborhood. But polls show that the majority of New Yorkers support bike lanes by a margin of 56% to 39%. Bicycle advocate Caroline Samponaro of Transportation Alternatives calls that a_mandate.

Caroline: If this was an election, we would have already had our victory. The public has spoken and they keep speaking. And I think, more importantly, the public is starting to vote with their pedals.

A punctual person is in the habit of doing a thing at the proper time and is never late in keeping an appointment. The unpunctual man, on the other hand, never does what he has to do at the right time. __36__

There's a proverb which says, “Time flies never to be recalled.” This is true. __37__ The unpunctual man is for ever wasting his most valuable asset (财产) as well as others'. The unpunctual person is always complaining that he finds no time to answer letters, or return calls or keep appointments. __38__ He knows that he can get through his huge amount of work only if he faithfully keeps every appointment and deals with every piece of work when it has to be attended to.

__39__ If a person is invited to dinner and arrives later than the appointed time, he keeps all the other guests waiting for him. Usually this will be regarded as rude both to the host and the other guests.

Unpunctuality, moreover, is very harmful when it comes to one's duty. Imagine how it would be if those who are put in charge of important tasks failed to be at their proper place at the appointed time. __40__

A．They appear to be busy but never get well paid.

B．He is always in a hurry and ends up losing time.

C．Maybe nobody minds being kept waiting at a dinner party.

D．A lost thing may be found again, but lost time can never be regained.

E．But the man who really has a great deal to do is very careful of his time.

F．A man who is known to be habitually unpunctual is never trusted by others.

G．Failure to be punctual in keeping one's appointment is a sign of disrespect towards others.
