cellular calls require emergency operators to determine the location of the caller

(C) lines, thus automatically informing the operator of the location and phone number of the caller, the location of the caller on a cellular phone has to be determined by the operator (D) lines, and thus automatically inform the operator of the location and phone number of the caller, emergency operators have to determine the location of the cellular phone caller (E) lines, thus automatically informing the operator of the location and phone number of the caller, emergency operators receiving a cellular call have to determine the location of the caller

考点: 比较（Comparison） 逻辑表达（Logical Predication）

1) thus一般和and连用,来连接表示因果关系的结构

2) 用逗号将句子隔开,使得逗号前后两个句子变成独立的句子,每个句子都要有自己的主谓宾

3) unlike比较结构，要求比较对象对等。

(A) 关系代词where修饰lines,逻辑错误.

(B) 正确, and前后平行,travel… and thus automatically inform共同修饰calls

(C) 比较双方不对等,emergency calls和the location of the caller没有可比性; thus automatically

informing表达错误,这里不应该用伴随结构,而应该用and thus来连接两个存在因果关系的句子

(D) and前面有逗号,说明and后面应该是一个完整的句子,应该补出主语they,但这样会使得句子变得复 杂,直接去掉逗号构成动词的并列更好;比较双方不对等,emergency calls和emergency operators没有

可比性

(E) 比较双方不对等;句子不完整,整个句子的结构为:Unlike emergency calls…, emergency

operators receiving…整个句子没有谓语动词; thus automatically informing表达错误,这里不应该用伴

随结构,而应该用and thus来连接两个存在因果关系的句子

句子结构 : Unlike emergency calls that travel…and thus automatically inform…, cellular calls

require…to determine…

补充说明:

当句子中出现 like, unlike 等比较结构的时候,读选项时首先读 like, unlike 比较双方,中间的修饰等干扰 成分可以直接跳过,发现 like, unlike 比较双方不对应,直接排除该选项. 在出现 like, unlike 等比较结构 的题目中,比较双方的对应可以说是一定会出现的考点,因此可以先应用这一点,直接排除 2-3 个选项, 从而节省时间.
