Researchers have announced the result of two studies on the health effects of the drug aspirin(阿斯匹林). One study shows aspirin can sharply reduce the chance that a healthy, older man will suffer from a heart attack.
The study offered two new results from earlier findings. It said taking one aspirin pill every other day helped only healthy men over the age of fifty. It also said aspirin gave the greatest protection against heart attacks to men with low blood cholesterol(胆固醇) levels.
Earlier in the United States began a major aspirin study in the early 1980s. it included 22,000 healthy men doctors. All were between the ages of forty and eighty-four. More than 11,000 of the doctors took a harmless pill that contained no drug. The men did not know which kind of pill they were taking.
The doctors who took aspirin suffered 44% fewer heart attacks than those taking the harmless pill. 139 men who took aspirin suffered from heart attacks. Ten of them died. 239 men who didn’t take aspirin suffered from heart attacks. Twenty-six of them died.
The researchers said the doctors’ study provides clear proof that taking aspirin can prevent a first heart attack in healthy, older men. They said ,however, the result does not mean every man over the age of fifty should take aspirin. They said aspirin couldn’t help men who do not eat healthy foods, who smoke cigarettes and who are fat. The researchers said men who think they would be helped by taking aspirin should talk with their doctors first. The passage tells us that the new use of aspirin is___________.
| A．to treat heart disease. |
| B．to reduce pain while one suffers from a heart attack. |
| C．to help old people to be more healthy. |
| D．to reduce the chance of a heart attack in old men. |
Aspirin can help those who___________.
| A．work as doctors | B．are under 40 years old |
| C．are fat and smoke cigarettes | D．are older and healthy |
From the experiment we can conclude that about _________ of people who suffered from heart attacks without aspirin died.
| A．7% | B．11% |
| C．19% | D．44% |

Do you still get free plastic(塑料) bags from the supermarkets?
Free plastic bags are not allowed at shops and supermarkets in China, and people have to pay for them. The rule started on June 1, 2009. It came because our country tried to make litter less. Making super-thin (超薄) plastic bags has not allowed.
The Chinese once used about 3,000,000,000 plastic shopping bags a day, and they have caused pollution of the environment. The bags have become a main cause of plastic pollution because they are easy to break and people throw them away here and there. So the Chinese people are encouraged to bring their own bags for shopping.
What kind of shopping bag is the best to bring? Some students in Chongqing city have a good idea. They make their own shopping bags. They use old clothes to make cloth bags, and send them to their parents as presents. They also ask their parents and friends to use cloth bags instead of plastic ones. They think it is their duty to protect the environment. China made this rule because plastic bags were bad for the _______.
| A．environment | B．litter | C．shops | D．supermarkets |

When you are learning English, you find it not clever to put an English sentence, word for word, into your own language. Take the sentence "How do you do?" as an example. If you look up each word in the dictionary, one at a time, what is your translation (翻译)? It must be a wrong sentence in your own language.
Languages do not just have different sounds, they are different in many ways. It’s important to master(掌握) the rules(规则) for word order (顺序) in the study of English, too. If the speaker puts words in a wrong order, the listener can’t understand the speaker’s sentence easily.Sometimes when the order of words in an English sentence is changed, the meaning of the sentence changes. But sometimes the order is changed, the meaning of the sentence doesn’t change.
Let’s see the difference between the two sentences:"She only likes apples. " "Only she likes apples. "
When you are learning English, you must use it as the English speaker does.From the passage we know that _______when we are learning English.
| A．we shouldn’t put every word into our own language |
| B．we should look up (查阅) every word in the dictionary |
| C．we need to put every word into our own language |
| D．we must read word by word |
The writer thinks it is________in learning English.
| A．difficult to understand different sounds |
| B．possible to remember the word order |
| C．important to master the rules in different ways |
| D．easy to master the rules for word order |
We can learn from the passage that_______.
| A．the meaning of an English sentence always changes with the order of the words |
| B．the order of words can never change the meaning of an English sentence |
| C．sometimes different order of words has a different meaning |
| D．if the order of words is different, the meaning of the sentence must be different |
