Only when he returned ________ that the war had ended and the army had come back.

we tell

we told

did we tell

were we told

考查倒装句型。Only放在句首时，句子要用倒装语序；根据句意“我们被告知”可知，此处要用were we told。故答案选D。

It was last night ________ I saw the comet.

the time

when

that

which

强调句的结构是：It＋be＋强调部分＋that(who)＋主谓句。强调句的连词只有两个，that和who。当强调的部分是人，且为句子的主语时，才用“who”，其余用that。因此选C。

used to

used to be

used to do

was used to

考查词组和省略式，used to do“过去常常’,be used to do “被用来做”，句意是：--你现在是志愿者吗？--不但我过去是，去年我为市运动会工作。可以排除D项，因为这是省略句，完整的是I used to be a volunteer。英语中如果不定式的部分是重复上文可以省略to后面的内容，但是如果to后面是be动词或助动词have，就不省略。选B。

Inside the window hangs a         carved out of this piece of wood by the artist.

decoration

destination

departure

discipline

考查名词辨析。句意：窗户边上挂着一幅被艺术家由这块木头雕刻的装饰品。A. decoration装饰，装饰品；B. destination目标； C. departure 离开；D. discipline纪律。窗边应挂着装饰品。故选A项。

— Is it my age ________the boss minds?
—I’m afraid so. He will consider ________ necessary to have an experienced assistant.

which；it

that；it

which；that

that；that

考查强调句型和it的用法。第一空that与it is构成强调句型。第二空it是一个形式宾语，真正的宾语是不定式to have an experienced assistant，选B。

One of the man holds the view          the book said was right.

that

whether

what that 

that what

考查同位语从句及主语从句。句意：其中一个人认为这本书说的是对的。分析句子可知，the view后面接了一个同位语从句（     the book said was right.），从句句子成分齐全，应使用that 引导，连接词在从句中不做成分，无意义。在同位语从句中又有一个主语从句（     the book said），在主语从句中said 缺少宾语，应用what 引导，指代“......的（事情，东西）”。故选D项。
