问题 单项选择题

工学院学生的数学考试成绩比商学院学生的数学考试成绩要好。因此,工学院的数学教学方法比商学院的要好。
以下各项,如果是真的,都能削弱以上的结论,除了;

A.工学院的数学试题比商学院的容易。

B.商学院学生的基础普遍不如工学院。

C.商学院的数学教科书要比工学院的难。

D.商学院的数学教师比工学院的数学教师普遍工作更勤奋。

答案

参考答案:D

解析:选项A可以削弱题干的结论,因为工学院的数学试题比商学院的容易,那么,工学院学生的数学考试的成绩好于商学院学生数学的考试成绩就是理所当然的事情,丝毫也说明不了工学院的数学教学方法比商学院的要好;选项B指出不是因为教学差距,而是学生不同,是削弱选项;选项C说因为教材难度不同,也能削弱;选项n说的是商学院的数学教师比工学院的数学教师普遍工作更勤奋,但学生考试的成绩反而不如别的学校,这正说明了商学院数学教师的教学方法不如工学院的好,这不是削弱而是强化了题干的结论。

     One Sunday a few of us decided to take advantage of the first sunny day we'd have for ages to take a

trip down to the coast to visit the penguins again. Last time I went down there was a couple of months ago

and it was a dull cold day. Sunday couldn't have been more different-clear skies and sunshine made it feel

like summer, although it was still -25°C.

     Six of us drove to the coast. It was the first time we'd been off the base on our own without our field

assistant, so it had a slightly different feeling-more like a few friends going to the seaside than an Antarctic

field trip! When we reached Windy Creek, we luckily caught sight of quite a few small flying seabirds, which

are seldom seen there.

     Once on the sea ice we found that some of the more curious penguins had wandered over from the main

group to come and check us out. We'd been told that then they were nursing their chicks (刚孵出的幼雏)

and they would be more careful and nervous than last time, but that didn't seem to be the case. We walked

across to the main group which were stretched for a couple of miles along the coast. We sat down for some

sandwiches and soon found ourselves surrounded by many curious observers. Without any attackers on land,

they were very brave and came within a meter of us to pose (摆姿势) for photos.

     Before heading back, we spent a few hours on the sea ice watching the penguins and their chicks, which

had grown dramatically (明显地) since our last visit. It was such a nice day.

1. When did the trip most probably happen?

A. On a dull Sunday.

B. On a warm Sunday.

C. On a summer Sunday.

D. On a winter Sunday.

2. It can be inferred from the second paragraph that the six people _____.

A. felt a little nervous

B. felt a little excited

C. were left all by themselves on their Antarctic base

D. got bored with staying with their field assistant

3. What does the writer mean by saying "but that didn't seem to be the case"?

A. They were told a lie.

B. A wrong decision was made.

C. The truth was the opposite.

D. They didn't believe what they were told.

4. The six people did the following during the trip EXCEPT _____.

A. feed the penguins

B. take pictures of the penguins

C. enjoy watching flying seabirds

D. watch the young penguins
