() 1.—What happened to Tom?
—He was crossing the street ______ a motorbike hit him from behind.

A.while
B.when
C.until
D.because

B

根据语境，“他正在过马路时，一辆摩托车从后面撞了他”。when引导时间状语从句，主句用过去进行时，从句用一般过去时，符合“be doing...when...”结构；while引导时间状语从句时，主从句通常都用进行时；until表示“直到……”，because表示“因为”，均不符合句意。

() 2.I enjoy learning English ______ it takes me a lot of time.
A.unless
B.though
C.because
D.for

B

分析句子结构可知，句子前后两部分存在转折关系，即“我喜欢学习英语”和“它花费我很多时间”之间存在让步关系。unless表示“除非”；though表示“尽管”；because表示“因为”；for作连词时表示“因为”。根据句意，只有though符合语境，表示“尽管学习英语花费很多时间，但我还是喜欢学”。

( ) 3.Read the sentence. "Since he can't answer the question, you'd better ask someone else." The underlined word "Since" is used to ______.
()
A.show time
B.express a result
C.show a reason
D.give an example

C

在这个句子“Since he can't answer the question, you'd better ask someone else.”中，"Since"引导的是一个从句，说明主句“you'd better ask someone else”的原因，即“因为他不能回答这个问题”。选项A表示时间，但"Since"在此处不是用来表示时间的；选项B表示结果，但"Since"引导的是原因状语从句，不是结果状语从句；选项D表示举例，但"Since"在此处并不是用来举例的。因此，"Since"在这里是用来表示原因的，与选项C相符。

( ) 4.—How long have you been away from your hometown?
— two years ago.

A.Since
B.For
C.In
D.From

A

问句是询问离开家乡多久了，答句中有“two years ago”（两年前），这是一个时间点。“since + 时间点”用于现在完成时，表示从过去某个时间点开始一直持续到现在的动作或状态；“for + 时间段”表示动作或状态持续的时长；“in + 时间段”常用于一般将来时；“from”单独使用不能表示这种时间关系。这里用“since two years ago”符合语境。

() 5.All except Tom have passed the exam because he ______ lots of classes.
A.left
B.forgot
C.missed
D.lost

C

根据语境“除汤姆外所有人都通过了考试”，原因应是“他缺了很多课”。“miss classes”表示“缺课”，符合语境。left（离开）、forgot（忘记）、lost（丢失）均不符合“缺课”的含义。

() 6.—Why did you come back so late today?
—______ it was raining heavily when the meeting was over, we had to wait until it came to a stop.

A.As
B.Since
C.For
D.Because

D

此处回答why引导的问句，强调直接原因，应用Because。As和Since引导原因状语从句时，语气较弱，常置于句首；For表示补充说明的原因，一般不置于句首回答why。
