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。

---Have you moved into        new office?

---No, the building is under          construction.

a; the

the; /

/; the

/; /

考查冠词。--你搬到新办公室了吗？--没有，大楼正在建设中。new office 谈话的双方都知道，所以是特指，需要用定冠词the,第二句under construction 指“正在建设中”，是固定搭配。故选B项。

The teacher was so pleased with the progress that I had        in my study this term that she sent me an English-Chinese dictionary.

made

had 

kept

graded

考查动词辨析。句意：老师对我在这学期在学习上取得的进步非常满意，寄给我一本英汉词典。分析可知hat I had        in my study this term 应是之前名词the progress的定语从句，先行词在从句中属于固定结构make progress“取得进步”的宾语。故选A项。

We’ll make the final decision on our scheme. ______ you change your mind, please inform us as soon as possible.

Should

Were

Would

Had

考查虚拟语气的省略。句意：我们将对我们的计划做最后决定。如果你改变主意，请尽快通知我们。根据语境，此处用虚拟语气，表示与将来相反，从句用should+动词原形，省略if，should提前，陈述句是：If you should change your mind……。故选A。

         Jixi today is more beautiful now. Mr.Jakson said he would visit it         third time.

The; /

The; the

/; a

The; a

考查冠词。句意：今天的鸡西市更漂亮了。Jakson先生说他将又一次来到这里。第一空“鸡西市”应用定冠词；第二空“不定冠词a/an+序数词+名词” 强调在已知数量上在累加一个，且 third为辅音音素开头的单词，应用a。故选D项。

Though ____ the dangers of smoking to their health, smokers still find it hard to give up smoking.

aware of

are aware of

be aware of

考查状语从句的省略：句意：虽然很多经常吸烟的人已经意识到抽烟对他们健康造成了很严重的后果，但是他们仍然发现很难戒烟。Though引导的让步状语从句是省略句，完整的句子是：though smokers are aware of the dangers of smoking to their health。当主从句的主语一致的时候，可以省略从句的主语和be动词，选B
