Our flat was on the fifth floor but you could still hear the roar of the ocean and see the stars at night. I used to take long walks along the water. The food in town was delicious and the people were very friendly. The area was very quiet and peaceful, and fairly deserted.

The last evening of our vacation, however, we all heard strange footsteps following closely behind us as we were walking up to our flat in the holiday centre. We turned around and noticed a fairly young man moving very rapidly across the beach and getting closer to us. He was tall and wore a baseball cap. We couldn’t see his face and he was approaching us very rapidly. The man’s actions made my dad very nervous. Dad warned us that we’d better try to make it to our flat as quickly as possible. I didn’t like my dad’s voice; I could hear fear in it. It was late and we were all alone. We didn’t have any cell phones on us. I never saw Dad as worried as he was then and I knew that something was terribly wrong. The sense of fear started to overwhelm Mom and me. We had had such a good time in town. Now, the night was rapidly turning into a dangerous situation.

We could hear the man’s footsteps getting closer. Dad’s face was almost pale. The so-called intruder (侵入者) had moved nearer and nearer when all of a sudden, the nearby vending(自动贩卖) machine started going crazy and spitting out cans of soda! The noise actually scared the intruder and he ran out of sight. My parents were shaking, but we all turned around to see who had put money into the vending machine downstairs, and actually saved us, but no one was around at all. Not a soul.

It’s one vacation I will never forget.

In 1971 a young man who grew up very poor was travelling across the country, trying to make a new start for himself. Along the way he had completely run out of（用光） money and was forced to spend the night in his car. This continued until one morning, after a week of sleeping in his car, he walked nervously into a restaurant and ordered a big breakfast.

After eating his first good meal in weeks, he found himself lying to the waiter, telling him he had lost his wallet. The waiter, who was also the owner, walked behind the chair where the young man had been sitting. He bent down, and came up with a $20 bill that looked as if it had fallen on the floor and said, “Son, you must have dropped this,” the owner said. The young man couldn’t believe his luck! He quickly paid for the breakfast, left a tip, bought gas with the change, and headed West.

On the way out of town, he began to understand what the owner did. Maybe nobody dropped the money at all. “Maybe that fellow just knew I was in trouble and he helped me in a way that didn’t embarrass(使尴尬)me. So I just made a promise to help other people if I can.”

Later, he worked very hard and became a rich man. Now he lives near Kansas City. Each year he gives away thousands of dollars. He is known as the “Secret Santa” because at Christmas time each year, he personally hands money out to those on the street and at restaurants. Last year, he gave more than $50,000 away in Kansas City.

       Air pollution, such as haze, has become a serious problem around the world. Besides wearing a mask, what else can we do to protect ourselves from the dirty air?

    Scientists have developed a new inhaler (吸入剂) that can reduce the effect air pollution has on people. It could help millions of people who are suffering from air pollution, the Guardian reports.

    This inhaler is developed by German company Bitop and contains a molecule (分子) named Ectoine. The molecule creates a layer (涂层) that protects lungs from polluted air. It’s reported that the inhaler will be affordable to most people when it comes to the market.

    Air pollution kills more than three million people a year worldwide and leads to health problems like lung and heart disease and strokes, according to a 2016 research project in the journal Nature. It is also linked to brain disease, mental illness and diabetes (糖尿病).

    Andreas Bilstein at Bitop believed that the inhaler could be useful around the world, because air pollution is not just a European problem: “Especially in Asia － China in particular － the demand for such a product is even higher.”

    Many Chinese cities have been suffering from haze. According to World Health Organization, two of the 10 most polluted cities in the world in 2015 were in China. About 800,000 deaths that are linked to air pollution take place in the country every year.

    However, such inhalers should never be an excuse for not trying to stop air pollution, said Professor Jean Krutmann at the Leibniz Research Institute for Environmental Medicine. “The best thing is that we have clean air and we don’t need any prophylactic (预防性的) treatment,” he said.

28. What is the new inhaler?

29. From the third paragraph, we learn that ______.

A. the inhaler comes from a US company         

B. the inhaler is named Ectoine

C. a molecule in the inhaler forms a layer on lungs  

D. the inhaler’s price will not be too high for most people

30. Which of the following is NOT true?

A. Air pollution kills millions of people a year worldwide.  

B. Air pollution can cause mental illness.

C. There are no air pollution problems in Europe.         

D. Air pollution is a serious problem in China.

31. Which is Professor Jean Krutmann’s opinion?

A. Such inhalers mean much to people.   

B. We should take action to control air pollution.

C. We can depend on inhalers to solve air pollution problems. 

D. We’d better produce more medicines to treat lung diseases.    

One of the most important things in the world is friendship. In order to have friends, you have to be a friend. You have to be with them in both good and bad times. In return, they will be there for you. But how can you be a good friend?

  Listen. Listen when they are talking. Keep eye contact. Don't say anything unless they ask you a question. Sometimes you're not required to have anything to say; they just need someone to talk to about their feelings.

  Help them. If your friends are ever in need of something, be there to help them. You should try to put them first, but make sure you don't become their slave (奴隶). Try to take an extra pencil or pen with you to classes as they may forget to take one.  Have a few extra dollars in your pocket in case they forget something they need.

  Be there for them. Try to make something for your friends to help make them feel better in hard times. Making cards and baking things are among the nicest things you can do for a friend when they are in hard times. Marilyn Monroe once said, "I'm selfish, impatient (急躁的) and a little insecure. I make mistakes, and I am out of control and at times hard to deal with. But if you can't handle me at my worst, then you surely don't deserve (值得) me at my best. "Always remember this! If you don't want to deal with your friends when they're depressed, then you don't deserve to be with them during those parties where you have a good time!

  Try to make plans with your friends. Go shopping, go for an ice cream, have a party, go to a movie and so on. Make time to know each other even better by doing something you both enjoy. These are the things you'll remember once you're all long graduated when looking back on your life!

  C. To get to know more friends.      D. To know what is worth doing.

If happy is what you want to be, you must take responsibility and stop expecting things or people to make you happy. You are the source of your own happiness, so stop looking elsewhere.    36    Here are a few ways for you to follow:

Be thankful to others.    37    It is too easy to take those around us for granted. Show them the same consideration you would like shown to you.

   38    This goes beyond(超过) politeness; it is a form of giving. Treat everyone you meet as if they have a big sign on their chest saying “make me feel important.” If you do this you will discover a hidden source of joy.

Perform acts of kindness. Don’t wait to be asked.    39    It doesn’t need to be a big thing, hold the door for a stranger, or smile at anyone you make eye contact with. Look for chances to make others feel good.

Make a decision to be happy. This is the most important step on the road to a happy life.    40    You are the key to your own happiness, so go ahead, unlock it once and for all.

A. Respect other people.

B. Be polite to other people.

C. Instead of looking for happiness, start creating it.

D. You can change your feelings by acting the way you want to feel.

E. If you see a chance to do something nice for someone else, do it!

F. Simply make up your mind to be the happiest person you know, and you will be.

G. Be grateful to the people in your life, and practice saying thank you for any politeness they show you.
