问题 单项选择题

据交通部去年对全国十个大城市的统计,S市的汽车交通事故率最低。S市在前年实施了汽车特殊安检制度,提高了安检的标准和力度。为了有效降低汽车交通事故率,其他大城市也应当像S市那样,对本市的汽车实施特殊安检。
以下哪项如果为真,最能削弱题干的叙述

A.在上述十个大城市中,在S市行驶的汽车中外地汽车所占的比率最低。

B.在上述十个大城市中,在S市行驶的汽车交通事故中外地汽车肇事所占的比率最低。

C.在上述十个大城市中,在S市行驶的汽车的总量最少。

D.S市去年的汽车交通事故的数量少于前年。

E.在上述十个大城市中,H市也实行了和S市同样的特殊安检制度,但去年其交通事故率要高于S市。

答案

参考答案:B

解析: B选项指出,在其他城市的交通事故中,外地车肇事的比例都比S市高,而安检只是对本市车辆进行的,因此其他城市效果未必如S市好。A和B的区别在于,没有把对象缩小为肇事车辆,如果外地车都很安全,则其比例多高并不重要。C无法削弱,因为不知道S市的车辆具体有多么少,是否能少到影响交通事故率的地步。E削弱力度很低,因为不清楚H市的其他交通情况如何。如果想用反例来削弱,必须指出这个城市用了该措施之后,和自身往年数据比较,事故率没有下降。

阅读理解

You may not have heard the words “freshman fifteen” before, but they are very important for students who are entering university(大学). A freshman is a first-year college student. “Fifteen” means fifteen pounds---the fifteen pounds added to a student’s weight in his or her first year. There are a number of reasons why first-year university students gain(增加) weight; but it’s encouraging to know that freshmen don’t have to add these harmful fifteen pounds.

Mistakes choosing food

University kitchens serve(供应) many kinds of food. Some students choose unhealthy food, because now their patents are not nearby to help them choose. Some students visit the kitchen many times while studying. Late at night, some students get harmful fast food such as fish and chips with Coke to drink. Students also have less time for walking, running, and doing sports because of their schoolwork.

Eating right

If you’re careful, you don’t have to add fifteen pounds. Here are some ideas:

Think more about what you eat.

Eat plenty of vegetables and healthy meats.

Don’t eat desserts full of sugar; have fruit after dinner.

Try not to eat so much unhealthy food while you study.

It’s all right to have a little fast food sometimes---but not often.

Write down the foods you eat.

Walk, run, do sports---move and you will feel better!

Remember that the “freshman fifteen” can happen to anyone. Talk to your friends about it. Together, try to eat healthy food and not to eat unhealthy food. Walking, running, and playing sports is always more fun with friends. Help each other and you can have a healthy and happy freshman year.
