Article: Nobody likes staying at home in a public holiday, especially when the weather is fine. Last august we decided to spend the day in the country. The only difficulty was that millions of other people had exactly the same idea. We moved out of the city slowly behind a long line of cars. But at last we came to a quiet country road and after some time, stopped at a lonely farm. We had brought plenty of food with us and we got it out of the car. It was very peaceful in the cool grass until we heard ringing at the top of the hill. What we saw made us pick up our things and run back to the car as quickly as possible. There were about two hundred sheep coming towards us down the path.

No

Article: There is an English saying: "Laughter is best medicine." Until recently, few people took the saying seriously. Now, however, doctors have begun to look into laughter and the effects it has on the human body. They have found that laughter really can improve people's health. Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their heart, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercises. It increases blood pressure, the heart beating and breathing. It also works several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial. Other tests have shown that laughter appears to be able to reduce the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group that tolerated the pain for the longest time was the groups which listened to a funny program. The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemicals in the brain which _ both stress and pain. As a result of these discoveries, some doctors in the United States now hold laughter clinics, in which they help to improve their patients' condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those who are caused by laughter.
Question: The main idea of the passage is _ .
Options: (A) laughter and physical exercises have similar effects. (B) smile can produce the same effects as laughter (C) pain can be reduced by laughter (D) laughter is best medicine
Asnwer: C
No

Article: Talking plants might sound like characters in a fairy tale. But recent scientific studies have shown that plants communicate with each other and with other living things in a surprising number of ways. To understand them, scientists say, we just have to learn their language. Farmers are especially interested in what plants have to say. "Plants are able to communicate with all sorts of organisms . They can communicate with giant bacteria, with other plants and with insects. They do this chemically," said Cahill, an Ecology Professor of the University of Alberta in Canada. Plant scientists are just beginning to understand this chemical "language". Cahill says studies have shown, for example, that plants can evaluate conditions in their immediate environment and take appropriate actions. Plants have an ability, for example, to signal pain or discomfort caused by anything from temperature extremes to an insect attack. Jack Schultz, a professor of chemical ecology at the University of Missouri, says when a plant senses that it's being eaten, it cannot walk away from trouble; on the contrary, it will release a chemical vapor that _ other plants nearby. "Their language is a chemical language, and it involves chemicals that move through the air that are easy to be changeable, and most of all are smells that we are familiar with," Schultz explained. "All plants responded to the attack by changing their chemistry to defend themselves," Schultz recalled. "But we were quite surprised to find that nearby plants also changed their chemistry to defend themselves, even though they were not part of the experiment." Studies have also shown that plants under attack release pleasant chemicals. Those chemicals attract friendly insects that attack the pests eating the plant. In the end, plants' ability to communicate their needs--and our ability to understand them--could help farmers reduce the use of poisonous chemicals, cut operating costs and limit damage to the environment.
Question: The recent scientific studies have shown that plants can _ .
Options: (A) communicate with other living things in a chemical way (B) hardly react to any sudden change in temperature (C) use a very special chemica1 language which is familiar to us (D) respond to the attack by giving off poisonous chemicals
Asnwer: B
No
