Question

    Don't drive your kids to school. Let them ride a bike to school.

In England 8.3 million children travel to school every day. It is reported that only a small number of pupils cycle to school (under 2%), although one in three children would actually like to.

Experts say that to stay healthy, children need at least one hour of moderate (适度的) exercise every day. But only six out of ten boys and four out of ten girls get that. One of the reasons is that parents have developed a habit of driving their children to school when they could just walk or ride a bike to school.

Teachers often say that children who walk or ride a bike to school are more ready to listen to their classes, ask and answer questions in class than those driven by car, and the school journey is a good chance for children to learn about road safety and other life skills. Also, for many children, riding a bike is more fun than going to school by car.

Most parents know the benefits. Then what's stopping them from letting their kids ride a bike? Safety is the number one worry for them. But actually riding a bike is not as dangerous as parents think it is.

When you decide to buy a bike, you should be aware (意识到) that a bike that is too big or too small is dangerous. Don't try to get a bike that your child will “grow into”. Get the right size in good working order. Generally, 20­ inch wheels are on bikes for 5-8 year old; 24 ­inch wheels are for 9-11 year old; 26 ­inch wheels are suitable for those over 11, and some older children should even take bikes with 28 ­inch wheels, but the main thing is that the bike fits your child.

【解析】

这是一篇说明文。本文提出要让学生骑自行车去上学，而不是家长开车送学生去上学。同时介绍了不同人对于此观点的看法，如专家、教师、大多数的家长。最后，作者为家长给学生买自行车提出建议即选择适合学生的自行车。

1.推理判断题。由第一段“Don't drive your kids to school. Let them ride a bike to school.”及最后一段“When you decide to buy a bike, you should be aware (意识到) that a bike that is too big or too small is dangerous. Don't try to get a bike that your child will “grow into”.”可知，作者给家长们提出不要开车送孩子上学而是要让孩子骑自行车去上学，并且在最后一段给读者也就是家长们提出购买自行车的建议。所以本文是写给那些开车送学生上学的家长们的。故选C项。

2.细节理解题。由“Experts say that to stay healthy, children need at least one hour of moderate (适度的) exercise every day.”可知，专家认为适度锻炼可以保持健康，及下文中提到只有少数学生能适度锻炼，因为家长选择开车送孩子。由此判断A项正确；由第三段“Teachers often say that children who walk or ride a bike to school are more ready to listen to their classes, ask and answer questions in class than those driven by car...”可知，老师们认为骑车上学的孩子在课上更积极，由此判断B项正确；由第三段最后“Also, for many children, riding a bike is more fun than going to school by car.”可知，孩子们认为骑车比坐车去学校更有趣，由此判断D项正确。因此错误选项是C。故选C项。

3.细节理解题。由第四段“Safety is the number one worry for them.”及上下文可知，家长不让孩子骑车上学的原因主要是担心孩子的安全问题。故选B项。

4.细节理解题。由文章最后一段24 inch wheels are for 9-11 year old可知，24英寸的轮子适合9到11岁之间的孩子骑。题目中问10岁的孩子适合多大尺寸的自行车，10岁在9到11岁的范围内。故选B项。
