2. Ann: All the campers at Camp Winnehatchee go to Tri-Cities High School

Bill: That’s not true. Some Tri-Cities students are campers at Camp Lakemont.

Bill’s answer can be best explained on the assumption that he has interpreted Ann’s remark to mean that

(A) most of the campers at Camp Lakemont come from high schools other than Tri-Cities

(B) most Tri-Cities High School students are campers at Camp Winnehatchee

(C) some Tri-Cities High School students have withdrawn from Camp Lakemont

(D) all Tri-Cities High School students have withdrawn from Camp Lakemont

(E) only campers at Camp Winnehatchee are students at Tri-Cities High School

我选的是d，而正确答案是e。请解释？是不是d中的withdrawn from导致意思不对的？

题中只说some students are campers at Camp Lakemont,没有说ALL，所以无法推出D呀。

A说：All campers at Camp Winnehatchee go to Tri-Cities High School

B说：That’s not true. Some Tri-Cities students are campers at Camp Lakemont.

由此可见：B 否定A的理由是：因为有些Tri-Cities students 是 campers at Camp Lakemont，所以A说的所有的campers at Camp Winnehatchee 到Tri-Cities High School这一命题是不对的，那么B的前提必须是，每一个Tri-Cities student都必须是a camper at Camp Winnehatchee.只有E有这个意思。

表达能力不太好，罗嗦了一点，不知说清了没有

唉,这个题都问了这么长时间了,也没有人给出一个明确一点的答案,我脸皮厚,来试试吧.

A说:所有的CW的营员都去了T学校

B说:不见得,一些T学校的学生是CL的营员.

B把A的意思理解反了,B理解为"所有T学校的学生都是CW的营员."  Icyeye mm理解这个肯定没有问题.

而E选项正是这个意思,即:只有CW的营员在T学校.因此T是对的.

至于D选项, 首先,A 没有提到CL,我们就不能妄加推论认为A的表述里面暗指CL,这就已经能够排除

其次是withdraw from 的意思,意思是"从...退出". A没有说过吧.

因此E选项是正确地.
