问题 单项选择题

加利福尼亚当局要求司机在通过某特定路段时,在白天也要像晚上一样使用头灯,结果发现这条路上的年事故发生率比从前降低了15%。他们得出结论说,在全州范围内都推行该项日间开灯的规定会同样地降低事故发生率。
下列哪项,如果正确,最能支持作者的论断

A.由于可以选择其他路线,因此所测试路段的交通量在测试期间减少了。
B.司机们对在该测试路段使用头灯的要求的了解来自于在每个行驶方向上的三个显著的标牌。
C.在某些条件下,包括有雾和暴雨的条件下,加利福尼亚的大多数司机已经在日间使用了头灯。
D.全面地推行该项目间规定后,对头灯灯泡的损耗速度要高于现在的水平,因此将需要更频繁地更换灯泡。
E.该测试路段在选取时包括了在加利福尼亚州驾车时可能遇见的多种路况。

答案

参考答案:E

解析:论证论据范围是“某特定路段”,因此,存在论据的普遍性不足的缺点。E选项的信息弥补了这一缺点,所以最能加强。

beep …beep … There went the bell! Robbie opened his eyes. He had been sitting in the room for a whole day, and now it was time for him to do something.

Robbie looked out of the window. It was still snowing heavily and there was ice on the window. It was another cold day. Robbie was told to turn the heat on before the family got home. And he did it.

Then Robbie was told to do some cleaning work at once. It was an easy job for him, but a tough one for his master, Helen. He kept on working until every room was clean and tidy.

For now, he had to cook supper for the family.

The first thing Robbie did was to get the big pot(锅) in the kitchen. Then he put some water in the pot and put it on the stove. He used one of his hands to cut up a chicken and added the pieces to the water to make a good soup. Then he got some tomatoes, cabbages and carrots to make a vegetable salad.

At ten past eight he laid the table. Then he put some bread, the chicken soup and the salad on it. What a sweet smell! The moment he turned on the lights, the whole family came home.

“The soup smells great, Victor,” said Helen. “You really know how to tell Robbie what to do.”

Robbie is one robot that really saves the family a lot of work.
