[单项选择]When the press release arrived in our inboxes, we knew what would happen next. A Nobel laureate had stated that antioxidant supplements "may have caused more cancers than they have prevented. "
Even the most fad-friendly sections of the UK media were bound to cover the story.
In reality, Professor James Watson was only restating what we at Cancer Research UK have been pointing out for years. Large studies have repeatedly shown that, with the possible exception of vitamin D, antioxidant supplements have negligible positive effect on healthy people, at least in terms of important things such as preventing people getting cancer or dying prematurely. And some supplements—notably vitamins A, E and beta- carotene—even seem to slightly raise the risk of disease and early death.
It’s a topic we at Cancer Research UK come back to again and again on our science blog and on our social media pages. But huge swatches of the public remain convinced that "antioxida

[单项选择]When we see well, we do not think about our eyes very often. (79) It is only when we cannot see perfectly that we realize how important our eyes are.
People who are nearsighted can only see things that are very close to their eyes. Everything else seems blurry(模糊的).Many people who do a lot of close work, such as writing, reading and sewing, become nearsighted. Then they have to wear glasses in order to see distant objects clearly.
People who are farsighted 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.

[单项选择]第二篇When Our Eyes Serve Our Stomach
Our senses aren’t just delivering a strict view of what’s going on in the world； they’re affected by what’s going on in our heads. A new study finds that hungry people see food-related words more clearly than people who’ve just eaten.
Psychologists have known for decades that what’s going on inside our head affects our senses. For example, poorer children think coins are larger than they are, and hungry people think pictures of food are brighter. Remi Radel of University of Nice Sophia-Antipolis, France, wanted to investigate how this happens. Does it happen right away as the brain receives signals from the eyes or a little later as the brain’s high-level thinking processes get involved.
Radel recruited 42 students with a normal body mass index. On the day of his or her test, each student was told to arrive at the lab at noon after three or four hours of not eating. Then they were told there was a delay. Some were told to come back in 10 minutes; o
