This is a story that can teach us a good lesson. One day, a man in rags begged from door to door along the street. With an old wallet in his hand, he was asking for a few coins to buy something to eat. He kept complaining about his bad fortune and kept __36__ why those who had so much money were never __37__ and were always desiring more.
“As far as I'm concerned, if I had only enough to ___38__ and to wear, I would not want anything more.”
Just at that moment Goddess Fortune, who came down the __39__ saw the beggar and said to him, “Hi, I have wished to __40__ you for a long time. Now, open your __41__ and I will pour my gold into it. But I will do that only on this __42__ : All that falls into the wallet will be pure gold; but every piece falling upon the __43__ shall become dust. Do you understand？”
“I see.” said the beggar.
“Then you should __44__ ！It's obvious that your wallet is a(an) __45__ one, so don't load it too heavily，” said the Goddess Fortune.
The excited beggar could hardly __46__ to have gold. He quickly opened his wallet, and a __47__ of yellow coins was poured into it. The wallet grew heavier and heavier.
“Is that enough? Isn't it cracking？” asked Fortune.
“Never __48__ .It's still strong enough now.”answered the beggar.
The wallet was filled with so many coins that the beggar's hands began to __49__. “Ah, if only the golden stream would __50__ forever! Just a little more，” said the beggar, “__51__ just a handful or two.”
“There! It's full. The wallet will __52__ .” warned the Goddess, but the beggar requested, “It will __53__ a little more, just a little more.”
One more piece was added and the wallet split. The __54__ fell upon the ground and became dust. The greedy beggar had now __55__ but his broken bag.

It doesn't take a rocket scientist long time to figure out that there are better things you could do for your health than take deep breaths on a smoggy（烟雾的）day. A growing pile of research suggests that even relatively low levels of air pollution may be more harmful than previously realized, to both heart and lungs(肺). The latest articles from researchers, published this week in the New England Journal of Medicine, focuses on how particulate (微粒) matter from air pollution affects lung function.
“The effect of low levels of particulate pollution found in many urban areas is not unlike secondhand smoke,” experts say. Studies show that short-term effects from particulates include diminished（减少） lung function, coughing, wheezing, and heart attacks. Long-term exposure can also slow normal lung growth, damage lung airways, and increase the risk of dying from lung cancer.
Certain populations, such as the very old and the very young, are the most vulnerable to air pollution. However, even the most alarming studies conducted in the most polluted areas suggest that the average person's individual risk from exposure (暴露) is very slight. Relative risk numbers often seem more frightening than they actually are. For example, an earlier study published in the New England Journal of Medicine found that short-term exposure to traffic fumes tripled ( 成为3倍) the risk of heart attacks in heart-attack survivors.
Short of moving to the countryside or at least away from busy roads, shielding yourself from the effects of air pollution is not easy. Masks won't work. “At the very least,” suggests Murray Mittleman, a cardiologist at Harvard University, “people who regularly exercise outdoors near highways may want to consider remapping their route.”

A. easy to be hurt            B. easy to be protected
C. easy to be used            D. easy to be saved
68. The main idea of Paragraph 3 is _________.
A. that even small risk from particulate causes big problems
B. that air pollution often leads to heart attack
C. who are most likely to get affected
D. that we shouldn't worry about the average low risk

The influence of America is increasing in my country. Spanish people drink Coca Cola, wear blue jeans, watch Hollywood movies, listen to American music, and eat fast food, and they do these things every day.

I think that American movies are a good way to spread American culture because people are often influenced by what they see in the movies. Most of the programs and documentaries (纪录片) we watch on TV are from America, and most of the movies we go to see are made in Hollywood.

In the last few years, the government has tried to protect the Spanish movies. Now, in our cinemas, at least twenty percent of the movies which are shown must be from Spain or from other countries in Europe.

American culture is a part of Spanish life now. It’s certain that many things from America are as much a part of people’s lives as Spanish things. For example, Coca Cola is as familiar to everybody as any typical Spanish product. I’ve known about Coca Cola for my whole life.

However, it’s different with Western fast food. For example, I don’t think McDonald’s is as successful in Spain as it is in other countries. In my opinion, one of the reasons may be the lifestyle of the Spanish people. The Spanish people normally eat at home.

On the other hand, maybe McDonald’s hamburgers will eventually replace the famous Spanish tapas. It’s true that in every city in Spain you can find a McDonald’s, and it is more popular among the Spanish children than among the adults. In any case, it’s obvious that American culture is becoming more and more a part of our lives every day.

1. From the first paragraph we can know that ____.

A. the influence of America on Spain can be found everywhere

B. most Spanish people don’t like to listen to their own music

C. fast food spreads from Spain to the United States

D. some Spanish actors go to America to improve their acting skills

2. What plays an important part in the spreading of American culture in Spain?

A. American novels. B. Hollywood movies.

C. McDonald’s. D. American music.

3. Why does the author think that McDonald’s is not as successful as it is in other countries?

A. Its fast food contains too much fat.

B. He thinks it is unhealthy.

C. Spanish people seldom eat out.

D. Spanish adults don’t like its fast food.

4. What do you think Spanish tapas might be?

A. The name of a drink. B. The name of a restaurant.

C. A clothing brand. D. A certain kind of food.
