题目内容

【题目】Rather than tell your kid to stop doing something repeatedly, you should find out ________ they are doing it.

A. whoB. whyC. what D. whether

【答案】B

【解析】

试题分析：考查宾语从句连接词。本题_____ they are doing it.是介词后的宾语从句。这个宾语从句：they作主语，系动词are doing, it作doing的宾语，而who, what在宾语从句中作主语、宾语、表语，故此处排除AC；why“为什么”在宾语从句中作原因状语；whether“是否”在宾语从句中不作句子成分；句意：你应该弄明白为什么你的孩子这样做，而不是反复地叫他们不要这样做。故B正确。

Dear Miss Wang,

Knowing that our library is going to buy books, I’ d like to give some advices.

Popular science books is what we need most. Usually popular science books explain basic principles of nature in a simple and interesting way. They helped us understand science better and arouse our curiosity scientific discoveries.

In addition to read for knowledge, we read for fun and inspiration. That is why I recommend other category of books: literary books. Classic works, written by masters, present great thoughts through fascinated stories and language. They not only offer us a joy and excitement, but also encourage us to think critical.

I’ll be glad whether you can consider my recommendation.

This year, our school called on us students to make a good use of our time and do some socially practice during the holiday, so I found a job and began to work in a small restaurant. I thought it was easy, and it turned out to be a hard one by a matter of fact. I spend the whole morning washing dish and setting tables. I didn’t have lunch until it was two in the afternoon. After lunch, I immediately began to work again, does the same things until 11 pm. It took myself more than ten hours in a day to work there! However, through the hard work, I’ve come to understand the value of hard work. I’ve also realized what difficult it is my parents to support the family. Therefore, I am now determined to study harder to repay my parents.

【题目】Where do you keep ice? In the freezer, of course. That's what scientists might have thought when they were looking for a safe place to store ice from mountain glaciers from around the world. They’ve decided to store ice in Antarctica because global warming is causing some of the glaciers in places like the Alps to melt.

Jerome Chappellaz of the French National Centre for Scientific Research is involved in creating an ice vault (地下室）there. He says: “We are probably the only scientific community whose sample (样本) is in danger of disappearing from the face of the planet. If you work on rocks or on tree rings, the raw material is still here and will be for many centuries."

And why do scientists need to study ice from the Alps？Ice formed on the top of a mountain is made of snow accumulated over thousands of years. Trapped air bubbles (气泡) contain samples of the atmosphere that existed when that ice was formed. Ice is a record of climate. By examining ice, we know carbon dioxide in the atmosphere is higher now than in the last three million years. Researchers use this kind of data to build computer models and try to predict what might happen in the future.

The ice vault will be housed in a snow cave at the Concordia Research Station, which is operated by scientists from France and Italy. The ice samples will be sealed in bags and placed 10 meters below the surface at a constant temperature of -50*C. This will put the scientists’ minds at rest. Losing the ice samples would be a disaster, and nobody wants to see a mine of scientific knowledge lost forever in a giant pool.

【1】What is the researchers' purpose of studying ice?

A. To learn about climate.

B. To learn about the Alps.

C. To trap air bubbles.

D. To reduce carbon dioxide.

【2】Jerome compares ice with rocks and tree rings to state that ________.

A. ice should be stored at home

A. Its large mountains.

B. Its function as a freezer.

A. They consider it an easy job.

B. They’re not optimistic about it.

C. They think it will cause disasters.

D. They think it’s a reliable way.
