() 2.We’ll go out for a walk as soon as it .

A.stops raining
B.raining
C.stop to rain
D.rain

A

题干意思为“一旦雨停了，我们就出去散步”，“as soon as ”引导时间状语从句，在时间状语从句、条件状语从句中，若主句是一般将来时，从句用一般现在时表将来，根据该原则本题从句应使用一般现在时，同时根据题意应该选择“stop doing”表示停止正在做的事情。it为第三人称单数，stop需加s。

() 3.You mustn’t get off the bus the bus stops.

A.although
B.if
C.then
D.until

D

本题考查连词的用法，根据题意“直到公共汽车停靠，你才能下车”，“直到…才…”的英语表达为 “not...until...”，因此选择until符合题意，其他选项although（虽然），if（如果），then（然后）均不符合题意。

() 4.Tommy afraid of speaking English, but now he can speak English fluently.

A.uses to be
B.uses to being
C.used to be
D.used to being

C

根据"but now"可知前半句描述过去情况，"used to do sth"表示过去常常做某事，be afraid of是固定搭配，所以用"used to be"。

() 5.— you be very naughty, Peter?
— Yes. I always played tricks on others.

A.Were; used to
B.Did; used to
C.Were; use to
D.Did; use to

D

根据答句"Yes. I always played tricks on others."可知问句是询问过去是否常常做某事，应用"used to"结构。"used to"的一般疑问句需借助助动词"Did"，且"used"要还原为"use"，即"Did...use to..."。选项D符合要求。

() 6.If you free tomorrow, we won’t go for a picnic.

A.aren’t
B.won’t be
C.weren’t
D.don’t

A

本题考查条件状语从句中时态的用法。在条件状语从句中，如果主句是一般将来时，从句要用一般现在时表将来。此句中主句“we won’t go for a picnic”是一般将来时，所以从句“If you...free tomorrow”要用一般现在时，free是形容词，主语是you，其前应使用系动词are，否定形式为aren’t。

() 7.What was Jim doing the teacher came in?

A.while
B.and
C.when
D.but

C

本题考查连词when和while的区别用法。when表示突然或恰在那个时候，常用于“be doing...when...”结构，意为“正在做某事时，突然...”；while表示“与...同时，在...期间”，强调两个动作同时发生。本句表达“老师进来时，Jim正在做什么”，应用when。and表示并列或顺承关系；but表示转折关系，均不符合题意。

() 8.— The boy failed the English exam.
— he didn’t work hard.

A.If
B.Because
C.When
D.So

B

第一句说男孩英语考试不及格，第二句说明原因“他不努力学习”。Because表示“因为”，符合语境。If表假设，When表时间，So表结果，均不符合。

() 9.I’ll go swimming with you if it tomorrow.

A.won’t rain
B.doesn’t rain
C.will rain
D.rain

B

if引导条件状语从句，遵循“主将从现”原则，主句用一般将来时（I’ll go），从句用一般现在时。主语it是第三人称单数，否定句用doesn’t+动词原形，故选B。

() 10. Jim was a little boy, he liked playing basketball very much.

A.When
B.If
C.Before
D.After

A

分析句子，前半句“Jim was a little boy”描述过去的时间状态，后半句“he liked playing basketball very much”说明在该状态下的行为。“When”表示“当……时候”，符合“当吉姆还是个小男孩时，他非常喜欢打篮球”的语境。“If”表假设，“Before”表之前，“After”表之后，均不符合。
