1、His sister left home in 1998, and ______ since.
A. had not been heard of
B. has not been heard of
C. had not heard of
D. has not heard of
答案：B
解析：考查时态和语态。hear of表示“听说”，后面应该有宾语，故此处应为被动语态，排除C和D。前句意思是“他妹妹1998年离开的家”， 说明1998年前有音信，由此可判断下句意思是“她妹妹从1998年到现在以来一直没有音信”，因此是现在完成时态，故选B。
2、She brought with her three friends, none of ______ I had ever met before.
A. them
B. who
C. whom
D. these
答案：C
解析：考查定语从句。句意：她带来了三个朋友，我以前一个也没有遇见过。本定语从句的先行词是her three friends，后面是由“none of+关 系代词”结构引导的定语从句，关系代词指代人（friends）且充当of的宾 语，故需用whom。
3、Could I speak to ______ is in charge of International Sales please?
A. who

5、Edward, you play so well. But I ______ you played the piano.
A. didn’t know
B. hadn’t known
C. don’t know
D. haven’t known
答案：A

答案：B
解析：考查部分倒装。句意：将计算机应用于教学。结果，不仅教师能节约精力，而且学生也对课程更感兴趣。在not only... but also...结构 中，not only放在句首时，not only部分倒装，but also部分不倒装。

8、One of the most important questions they had to consider was ______ of public health.
A. what
B. this
C. that
D. which
答案：C
解析：考查代词。句意：他们不得不考虑的最重要的问题之一就是公 众健康问题。分析句子结构可看出they had to consider是定语从句，可见 was是主句谓语部分的系动词，根据选项可判断后面不是句子，不需要 疑问词，排除A和D。通过对句子结构的分析，空格应指代上文中 question这个名词，而that指代上文，this指代下文，故本题选C。
9、Everybody was touched ______ words after they heard her moving story.
A. beyond
B. without
