[不定项选择题]资料：What，if anything，do we gain by clinging to our antioxidant supplements？ Very little，according to an accumulating body of research. We don’t need massive doses of antioxidants，we need stress to compel our own bodies to create antioxidants.“Everybody thinks oxidation is bad，and that antioxidants are good，”says Dr.Jones，“That’s bogus. A little bit of poison is good.” That poison can actually come from plants，especially those that have survived harsh conditions. Foods that have survived harsh conditions make us stronger by stressing our bodies，not because they’re rich in antioxidants. As the science quarterly Nautilus explains，plants have developed an arsenal of chemicals to help them ward off insects and grazers. These“antifeedants，”when ingested by humans，trigger the body to release proteins and activate genes that “produce antioxidants，enzymes to metabolize toxins，proteins to flush out heavy metals，and factors that enhance tumor suppression.” Plants prepare your body to handle toxins in the same way as exercise prepares you to race-by stressing your body. And supplements，says Dr.Hooper，interrupt this process. “These antioxidant supplements are like a Trojan horse，”continues Dr.Hooper. They say，I’m a good guy. You guys go to sleep and while the defense is asleep the antioxidants get rid of any oxidation. It puts the defense-system’s army to sleep. While Dr.Jones acknowledges the benefits of vitamin E for muscle cramps and macular degeneration，he doesn’t approve the idea that it improves one’s physical performance. He suggests that athletes in intense contact sports such as soccer and football benefit from trauma. “Players have to be hit with pads on Tuesdays and Thursdays in order to compete on Sundays-they need that actual trauma.”he says. “Everything in our society is geared toward，How can we reduce stress？”adds Dr.Hooper. “When it should be just the opposite. We need stress. Stress is good. Why is stress good according to Dr.Jones？
A.It is good for muscle cramps.
B.It is good for macular degeneration.
C.It goes well with trauma.
D.It makes human body stronger.

[不定项选择题]资料：When we see well，we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are. People who are near-sighted can only see things that are very close to their eyes，Everything else seems blurry（=unclear）.Many people who do a lot of work，such as writing，reading and sewing become near-sighted. People who are far-sighted suffer from just the opposite problem. They can see things that are far away，but they have difficulty in reading a book unless they hold it at arm’s length. If they want to do much reading，they must get glasses，too. Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism. This，too，can be corrected by glasses. Some people’s eyes become cloudy because of cataracts. Long ago these people often became blind. Now，however，it is possible to operate on the cataracts and remove them. Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle. To prove this to yourself，look at an object out of one eye；Then look at the same object out of your other eye. You will find the object’s relation to the background and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distance as people with two eyes. The underlined word suffer in the third paragraph probably means______.
A.feel pain
B.imagine
C.are affected with
D.experience
