22.The senior official was the person______.（  ）

A.whose honor the ball was given

B.whom the ball was given for him

C.for him the ball was given

D.in whose honor the ball was given

22.D【解析】句意：这场舞会为了纪念这位高级官员而举办。分析句子可知，the person为先行词，在后面的定语从句作honor的定语，所以关系代词为whose，排除B和C。in one’s honor指“为了庆祝或纪念某个人”，排除A。故D选项正确。

23.The instrument as well as other spare parts ______ going to be airlifted soon.（  ）

A.be

B.are

C.is

D.will

23.C【解析】当主语后有no less than， with， along with， together with， accompanied by， as well as， rather than， including， besides， in addition to， except等时，谓语动词的单复数仍与主语的单复数保持一致。本题主语instrument为单数名词，谓语用is。故选C。

24.A vaccum tube is a glass tube from which most of the air has been removed，______an almost complete vaccum.（  ）

A.is creating

B.creates

C.creating

D.it creates

24.C【解析】句意：真空管是一种玻璃管，其中大部分空气已被抽离，造成一个接近真空的状态。“造成真空状态”是伴随主句“大部分空气被抽离”这个动作的状态，是同时发生的，因此要用动词ing形式。故选C。
