Question

Everyone tries to get to school on time. But when bad weather gives you trouble（麻煩）, can you still make it before the bell rings?

In northern China during spring, big sandstorms（沙塵暴）often make trouble for students and everyone else. When the sky is dark with sand, buses and cars all move much more slowly. Sometimes, people can’t even see for 20 metres.

Sandstorms usually happen in spring. This year, sandstorms started in late March. They have happened in more than 10 provinces (省) in northern China this year. More than 70 million people have had problems in those places because of the sandstorms.

People in southern China don’t have to worry about this kind of bad weather. Most of the sand comes from Gansu and Inner Mongolia（內蒙古）. In northern China, lots of places have few trees and don’t get much rain. People there have been cutting down too many trees. When there aren’t many trees, the ground can’t keep enough water. Over the years, the ground dries up and turns to sand. When spring comes and the ice melts（融化）, the ground becomes looser（更松散的）. Strong winds take the loose sand into the sky.

Sandstorms are bad for people’s health. If people breathe（呼吸） too much sand, they could cough or have asthma（哮喘）.

Sandstorms also give farmers lots of problems. Sometimes their sheep get lost in the storms and never get back home. The winds also tear down farmers’ houses.

What can you do to stop sandstorms? Here’s an idea: Ask your parents to help you plant some trees this spring.

If you see people cutting down too many trees, tell them about the dangers of sandstorms, and ask your government to stop them from cutting.

【解析】

試題分析：本文主要討論惡劣天氣即沙塵暴，給人所帶來的麻煩以及不便，尤其在中國北方的春天，大范圍的沙塵暴會給學生及每個其他的人帶來麻煩，公交車和私家車行動緩慢，能見度不足20米；沙塵暴對人的健康也會帶來危害，如哮喘�。簧硥m暴，也給中國的農民帶來很多問題，有時他們的羊會消失在沙塵暴中，有時他們的房屋會被大風吹倒�。患热簧硥m暴給我們的生活帶來各個方面的麻煩，作者也提出了阻止或者減少沙塵暴危害的一些辦法。

1.1】細節信息題。此題根據問題In which season do sandstorms usually happen? 詢問沙塵暴經常發生在哪個季節？定位到信息句Sandstorms usually happen in spring. 故可推知答案。故選：A。

2.2】細節信息題。此題根據問題Which of the following provinces in China is often hit by sandstorms? 以下中國的哪個省經常受到沙塵暴襲擊，定位到信息句，Most of the sand comes from Gansu and Inner Mongolia（內蒙古）可以推知，大部分沙塵來自于甘肅省和內蒙古即可推知答案。故選：D。

3.3】詞義猜測題。此題根據問題定位到tear down所在的句子，The winds also tear down farmers’ houses，根據常識，大風會刮倒房屋，即可推知答案。故選：B。

4.4】推理判斷題。此題根據問題what cannot be caused by sandstorms需要尋找沙塵暴所不能破壞的東西，A. Health problems，文中在第此段提出哮喘病Sandstorms are bad for people’s health. If people breathe（呼吸） too much sand, they could cough or have asthma（哮喘）推知此項正確； B. Traffic problems. When the sky is dark with sand, buses and cars all move much more slowly，推知沙塵暴也影響了交通問題，推知此項正確；C. The loss of farm animals. Sometimes their sheep get lost in the storms and never get back home，推知沙塵暴期間動物也會消失；推知此項正確；故選D。Noise pollution，文中未有出現。

5.5】推理判斷題。此題根據問題Which is not stated in the passage尋找文中沒有敘述的東西，使用排除法。A. Trees can help keep enough rain water 根據文中此句When there aren’t many trees, the ground can’t keep enough water.推知A項正確； B. More trees need to be planted 根據文中此句Ask your parents to help you plant some trees this spring. 推知B項正確；C. Some people are doing harm to the environment. 根據文中此句In northern China, lots of places have few trees and don’t get much rain. People there have been cutting down too many trees. When there aren’t many trees, the ground can’t keep enough water. Over the years, the ground dries up and turns to sand，推知人類對環境進行了多年的破壞推知C項正確； D. Sandstorms are the main cause of asthma（哮喘），此句在文中沒有直接說明，故此句錯誤。故選：D。
