If you always hate certain vegetables. you may be more than a picky eater. Instead, you might be a “super-taster”, a person     1     biter genes(苦味基因). Those people who have the “biter genes” are 2.6 times more likely to eat     2     (few) vegetables than others, according to a new study     3     (present)at the annual meeting of the American Heart Association.

“We don’t get the taste of food equally,” said Professor Duffy, an export in the study of food taste. “It could explain some of the differences in our food     4     (prefer)”. About half of us can taste bitter and sweet, so we are not especially sensitive to bitter food. Another 25% are called “non-tasters” to     5     bitter food might be a bit sweeter. The rest of us are     6     (extreme) sensitive to the bitterness that some     7     (plant)develop to keep animals from eating them.

Food scientists are trying to develop ways     8     (reduce)the bitterness in vegetables, in the hope that we can keep “super-testers” from rejecting vegetables. In fact, some vegetables we grow today     9     (be)much sweeter than before.

We might also try to use various cooking methods, either by adding me fat, sweetness, strong flavors like garlic     10     roasting them, to improve the taste of the vegetables.

I read this story the other day and I liked it very much. Now I’d like to share it with you.

A man     1     (sudden) felt very terrible one day and was taken to hospital. After he received some examinations, he     2     (tell) he was badly ill and wouldn’t live longer than one year. Hearing that, the man became     3     (depress). He was so worried about himself that he wanted to do nothing. It lasted for about a month. Then one day, he decided to make     4     change and do something that he had dreamed of     5     (do)—to travel around the world. The doctors were shocked when they     6     (learn) about it. They told the man that he might die on the way, but the man insisted on doing it. So he began his journey around the world.

He made friends     7     those he met on ships or planes. He enjoyed good food and visited beautiful places. He was in a happy mood every day and even totally forgot his     8     (ill).

He was still alive one year later. When he returned to his home country, he was happy and     9    (health).

We shouldn’t be anxious about it     10     something bad happens to us. Instead, we should overcome our anxiety. Things will not be as bad as we expect them to be.
