【題目】—My mother doesn’t think Tik Tok（抖音）is good _________children because there are some bad videos in it.

—I agree . Children should spend less time watching them.

A.atB.forC.withD.to

【答案】B

【解析】

句意：—我媽媽不認為抖音對孩子好，因為里面有些不好的視頻。 —我同意。孩子們應(yīng)該花費更少時間看它們。

考查介詞用法。be good at擅長，在某方面做得好；be good for對……有好處；with和……一起；to意為朝，向，根據(jù)后一句的原因是里面有不好的視頻，可知抖音對孩子不好，所以是短語is good for，用介詞for，故選B。

【題目】 Mike Myers is a teacher at Chauncey Rose High School in Terre Haute, Indiana. Last year, he taught his students about the world’s rain forests. They learned that rain forests are important because the plants and animals of the rain forest give us food, wood, and medicine.

Destruction of the world’s rain forests is a serious problem. Unluckily, rain forests are disappearing at a rate of 80 acres (英畝) per minute! As part of a class project, Myers’ students bought three acres of rain forest in Central America. They paid $25 per acre. The students hope that the land they bought will be protected and not destroyed. The students became so interested in rain forests that they decided to get a closer look at a real rain forest.

So this June, Myers and four of his students took a boat ride down a river. They saw alligators and crocodiles. In the middle of the week, a guide took Myers and his students into the rain forest. “The monkeys were not happy that we were in their forest. They broke small branches off the trees and threw them at us,” one of the students said, “It was a great learning experience for all us,” said Myers.

Each student chose something specific about Costa Rica to study involving the plants, animals, food, and culture. During the last few days the group had time to do fun activities. They went whitewater rafting and horseback riding, and visited Costa Rica’s active volcano.

Myers hopes to make the trip every year with a different group of kids.

Myers also talked about the big disaster about the rain forest fires in the Amazon—the lungs of the Earth. The Amazon forests produce 20% of the world’s oxygen (氧氣). Even if it’s just a small part of the rain forests that are destroyed, it’s a great loss to the whole world. That means, once an area of land burns, it doesn’t regrow as forest. Now Myers’ students know that we should try to protect the rain forests, or the last drop of water on the earth will be our tears.

【1】How much did Myers’ students pay for the rain forest they bought?

A.$25B.$75C.$80D.$2000

【2】What did Myers and his students do at the beginning of the trip?

A.They went into the rain forest.B.They bought acres of rain forest.

C.They took a boat ride down a river.D.They visited Costa Rica’s active volcano.

【3】The word “Destruction” in paragraph 2 probably means “Being __________”

A.discoveredB.developedC.describedD.destroyed

【4】What will cause “The last drop of water on the earth will be our tears”?

A.Killing some pigs and beef for meat.

B.Cutting down a large amount of trees in the forest.

C.Buying some fruits grown in the rain forest.

D.Traveling in the rain forest.

【5】The passage mainly shows that Myers and his students __________.

A.did something to protect rain forest

B.wanted to buy the rain forest in Costa Rica

C.were interested in the culture of Costa Rica

D.went to the rain forest for various fun activities.

【題目】 Some people may sneeze after touching a cute dog. Others may find it hard to breathe after eating a certain food. Why does this happen? That’s because they have allergies (過敏).

When a person is allergic to something, his or her immune system (免疫系統(tǒng)) mistakenly believes that this thing is harming the body. Some allergies may cause uncomfortable eyes or sneezing. Others may even make people stop breathing.

But why do people have allergies?

It can be because of their genes, which control what they look like, how they grow and how they develop.

You may be at risk for developing allergies yourself at some point in your life if one of your parents has eczema (濕疹) or food allergies, and they may develop in a certain order, Ogden told Gizmodo, a US technology and science website. A person may first have eczema in his or her childhood, and later see it develop into a food allergy.

But not all allergies are caused by genes. Some experts say that if we experience fewer infections (感染) when we are young, we are more likely to have allergies when we grow up.

According to Matthew Greenhawt from the University of Colorado, our immune system deals with infections and allergies. It tries to keep a balance between the two. But modern medicine protects us from developing various infections. This breaks the balance. Our immune system becomes more easily affected by allergies. It may think that normal things, such as certain foods, are dangerous and will try to protect us with an immune response.

根據(jù)材料內(nèi)容選擇最佳答案。

【1】People who have allergies may ________ according to the text.

A.be likely to have cancerB.find it hard to fall asleep

A.Few people are allergic to animals.
