Question

【題目】

1.People from north and south China have different habits. Do you know why? The answer is in their genes (基因) according to USA Today. More people from north China have a Special gene. It helps them digest (消化) meat and fat. Few people in the south have this gene.The gene helps people live more easily in the north. There is more meat and fewer vegetables there.

2. Global warming is causing many problems. It is making insects (昆蟲) eat more crops(莊稼), The Atlantic reported. Insects' body temperatures change with their environment. On warm days, their body temperature becomes higher than usual. So their metabolism(新陳代謝)becomes faster This means they need to eat more.They also breed (緊殖) more quickly on hot days.

3. Are babies carefree (無(wú)憂無(wú)慮) ? You might think so. But actually, 2-year- old babies care about what others think about them, according to a US study. Scientists used to think that this only happens in 4-year-old children. But a new study shows that the age is earlier. And 2-year-old children can change their behavior to get a more active response(反應(yīng))from others.

4. Mmm..chocolate smells So good. But do you know where chocolate comes from? Chocolate is made from cacao(可可豆).

【2】What can we conclude from passage two?

A.Insects' body temperatures always stay the same, never unchanged.

B.On hot days, insects' metabolism becomes more slowly that usual.

C.Global warming can make insects eat more and breed more quickly.

【3】Which of the following is true according to passage three?

A.No babies care about what others think about them.

C.A new study shows when and where people grew cacao.

【5】What's the best title for all the four passages?

A.Babies Also Care.B.Unbelievable Facts.C.New Scientific Discoveries.
