Part II Reading Comprehension

Directions: There are 4 passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D), and you should decide which is the best choice. (40 points)

Passage 1

Questions 26 to 30 are based on the following passage:

Just like children, deer often cross British roads to get to the other side. But the cost is the deer's life. At night, speeding cars hit and kill the animals. Now foresters are using natural animal instincts（本能）to prevent dangerous crossings.

In England, the British Forestry Commission has installed thousands of glowing red "wolf eyes" along woodland roads. The eyes are actually reflectors, plastic bars like the red reflectors on your bike. The ten-centimeter long bars are fixed on top of posts, with only these signs directed towards the woods rather than the roads.

When cars speed by, light rays from car headlights reflect off the reflectors' shining surface and flash into the woods. Deer are instantly scared by the wolf eyes ―even though wolves haven't hunted deer in Britain or even lived there for a hundred years!

Scientists think the glowing light imitates the "eye shine" of nightly beasts. (You've probably seen eye shine on cats. Mirror-like cells in the eyes reflect some light that hits them.) The deer must not have "forgotten" that a wolf can run up to 72 km per hour in hot pursuit, or can sniff（嗅）deer out from 2.4 km away. In some areas where "wolf eyes" keep watch, 90 percent fewer deer have been killed at night.

29. The success of "wolf eyes" proves that _____.

C) a wolf's smell is ten times more sensitive than man's

D) Britain has built many highways through woodlands

Passage 2

Question 31 to 35 are based on the following passage:

"Mind over matter" is an English saying meaning that we can control our bodies with our minds. Now scientists are finding increasing evidence that our mind can have a great effect on our physical health. Since our mind influences how we feel, it's not impossible to say that someone is ill just because he feels ill.

The influence of the mind on how well we feel is the basis of what is known as the placebo (which is Latin for "I shall please") effect. A placebo is a harmless, inactive substance. Patients are sometimes given placebo pills and begin to feel better because they believe that they have been given real drugs and expect to respond to them. The placebo effect is very strong: research on pain suggests that up to 30% of the effect of most painkillers is a placebo effect.

So if it's so powerful, why don't doctors use it today?

According to Dr. Persaud, they do. "Things like wearing a white coat, going to a hospital, being scanned（扫描）all have a very strong placebo effect," he says.

31. The English saying "mind over matter" means that _____.

A) sound mind is more important than good health

B) our mind has strong effect on our body

C) our physical health has nothing to do with our mind

D) mental health mainly depends on physical health

32. According to the first paragraph, if you feel ill, _____.

A) you don't need to see a doctor

B) you are still in good condition

C) it doesn't necessarily mean that you're physically ill

33. According to the passage, placebos _____.

A) are real effective pills

B) are not real drugs

C) can relieve all kinds of pain

D) may make patients feel worse
