    题目列表(包括答案和解析)

    When you look at your food, some ingredients are easy to see. For example, there is cheese on your pizza and butter on your bread. But our meals are also filled with ingredients you can’t see. And you might be surprised to learn just how much those hidden (隐藏的) ingredients affect your health.
    Salt is a perfect example of an ingredient that you might not notice, even when you eat a lot of it. More than 75% of the salt we eat is hidden in restaurant meals, fast food and processed (加工过的) food , such as French fries, hot dogs and even biscuits.
    Salt is important to us. It keeps our muscles (肌肉）working and our nerves (神经）sending  messages through the whole body. Salt can be used to clean teeth, to make our skin smooth or added to a relaxing bath. Salt is also used to help make food last (持续) longer.
    However eating too much salt can cause heart problems. For a long time, heart trouble has been regarded as an adult problem, but new research shows that salt is starting to affect kids. Then how much salt is safe for kids every day? Let's look at the following chart:
         Ages
    		   Amount of Salt Every Day
    1—3 years old
    		2 grams
    4—6 years old
    		3 grams
    7—10 years old
    		5 grams
    11 or more than 11 years old
    		6 grams
    Kids should not eat more than that.
    【小题1】The underlined word “ingredients” means “__________” in Chinese.
    A．配料B．热量C．营养D．脂肪

    阅读下面短文，然后根据短文内容选择最佳答案。

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

    　　In northern China during spring, big sandstorms often make trouble for students and everyone else．

    　　‘When we had a sandstorm last week, I had to get up half an hour earlier so I wouldn't be late for school,’said Xing Wei, a Junior 1 boy at Yaohua Middle School in Tianjin．

    　　Xing usually gets up at about seven and needs 20 minutes to get to school．But on sandstorm day, he needs 40 minutes．When the sky is dark with sand, buses and cars all move much more slowly．Sometimes, people can't even see for 200 metres．

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

    　　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．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 becomes looser．Strong winds take the loose sand into the sky．

    　　Sandstorms are bad for people's health．If people breathe 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 farmers' houses down．

    　　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 danger of sandstorm, and ask your government to stop them from cutting．
