A、relax
B、diminish
C、vanish
D、cover
答案：D
解析：cover his nervousness
A. that be
B. as to be
C. as be
D. as being
解析：参考解析:译文:现在笔记本电脑还很贵，不是人人都买得起。考点:固定搭配。”so+形容词/副词+as+不定式"属于固定搭配，表示”如此...以至于”，故选B。
A. whether
B. where
C. what
D. whom
解析：参考解析:连词用法。本题关键是看连接词在表语从句中担当什么成分。从句we should go there so early tomorrow中不缺少主干成分，所以连接词在从句中只能作状语或者不担当任何成分。只有whether作为连接词时在从句不作成分，符合题意。B项where在从句中作地点状语，但是从句中不缺地点状语;C项和D项是关系代词，在从句中只能作名词成分，不作状语。句意:我们现在讨论的第—个问题是明天我们是否应该那么早就到那儿。
A. got tired of
B. got up
C. got hold of
D. got rid of
解析：参考解析: get tired of意为"厌倦，厌烦"; get up意为"起床"; get hold of意为"抓住、把握住"; get rid of意为"摆脱、去掉”。根据题意，故选D。
A. whatever
B. whichever
C. whenever
D. however
A. who
B. that
C. which
D. whom
解析：参考解析:当定语从句的先行词前有the only，the very，thee last，the same等表示特定概念的修饰词时,定语从句的引导词只能用that，故选B。
A. is
B. are
C. have
D. has
解析：参考解析:由who引导的定语从句中先行词是the only one，关系代词在从句中作主语，所以动词应该用单数形式，且应该是主动语态，故选D。
A. does
B. did
C. should do
D. will do
A. against
B. with
C. to
D. for
解析：参考解析:题中ratio与介词to是固定搭配，the ratio of A to B的意思为"A与B之比率."，故选C
A. incredible
B. probable
C. imaginable
D. impossible
A. blamed
B. be blamed
C. would blame
D. to blame
解析：参考解析:不定式。to blame表示"为发生的某种坏事受指责”，常以主动形式出现却表示被动含义。句意: 关于打碎杯子的事，妈妈不知道该批评谁。
