范例探究

【例1】Do you have any idea ______ is actually going on in the classroom?

A.that

B.what

C.as

D.which

解析：what引导同位语从句,从句中缺少主语,要用what引导.

答案：B

规律点拨

同位语从句通常由that引导,但是疑问代词who,which,what和疑问副词where,when,why,how也可以引导同位语从句,但是,疑问代词和疑问副词前面的名词比较特殊.

【例2】Danby left word with my secretary ______ he would call again in the afternoon.

A.who

B.that

C.as

D.which

解析：that引导同位语从句,具体说明word的内容.

答案：B

规律点拨

为了考查学生判断能力,设计题目时往往绕圈子,如本句中同位语从句有时与从句分开,做题时一定要注意.

【例3】It was ______ back home after the experiment.

A.not until midnight did he go

B.until midnight that he didn’t go

C.not until midnight that he went

D.until midnight when he didn’t go

解析：这是一个强调句,对not until midnight进行强调,要用that连接.

答案：C

规律点拨

如果题目很难一眼就发现其中奥妙,要从源头递推,层层推出,更容易解题.如本题所示:“not...until”句型→“Not until+时间”在句首的普通句式→“Not until+时间”作为被强调部分的强调句.

【例4】I didn’t make great progress in my English study ______ my teacher had given me some advice on how to learn the language well.

A.unless

B.before

C.until

D.when

解析：本题考查连词区别,when都不能与否定词连用,先排除;虽然unless和until都能与否定

词连用,但unless常与将来时态连用,而until常与过去时或者将来完成时连用.

答案：C

规律点拨

unless和until在考查中经常形影不离,掌握二者用法的区别是高考必备.就是如果表示过去的情况就用not...until...,而表示将来的情况就用not...unless....把复杂的知识点简单化,是学习语法的好方法.

【例5】The ______ why Mr Smith didn’t turn up was not known by others.

A.cause

B.truth

C.reason

D.matter

解析：此处是一种逻辑方面的理由,即用来解释某种现象或者结果的理由,应当用reason.

答案：C

规律点拨

reason作先行词时,后面的关系词未必都是why,应当由动词决定,如:This is the reason that he told me.在句中reason作told的宾语,关系词为that 而不是why.

【例6】Everyone ______ Tom’s brother was able to swim across the river after b eing trained.

A.beside

B.besides

C.except

D.and

解析：beside表示“在……旁边,在……附近”;and不通,首先排除这两项.besides表示“除了……还有”,常与other,else,also,still等词搭配.而except相当于but,except意思为“除了……外没有”,一般与all,every,no以及它们构成的合成词等搭配.

答案：C

规律点拨

与except相关的短语有:except for说明整个基本情况后,对细节加以纠正;后面一般接名词.except that用来表示理由或者细节,修正前面所说的情况,后面必须接从句.except when后面接表示时间的句子,表示“除了某时间外、除了当……时”.

【例7】It was raining heavily.Little Mary felt cold,however,so she stood ______ for her mother.

A.close

B.closely

C.closed

D.closing

解析：close作动词的意思是“关”;作形容词或者副词的意思是“近（的）地;接近的（地）”.根据动词stood可以确定close作副词,为正确答案.

答案：A

规律点拨

在英语词类中,有许多形容词作副词用,而且表示具体的含义,而后面ly则表示抽象意义.wide（宽地）,widely（广泛地）；deep（深地）,deeply（深深地）；high（高地）,highly（高

度地）；close（近地;接近地）,closely（密切地）.

【例8】Having a trip abroad is certainly good for the old couple,but it remains ______ whether they will enjoy it.

A.to see

B.to be seen

C.seeing

D.seen

解析：It在句子中作形式主语,真正主语是主语从句; remain是系动词,后面跟表语.

答案：B

规律点拨

不定式作表语时,表示将来的动作,其否定式是在不定式的前面加not或者never;但是如果表示将来被动的动作,就用不定式的被动式.

【例9】—How far apart do they live?

— ______ I know,they live in the same neighborhood.

A.As long as

B.As far as

C.As well as

D.As often as

解析：as far as I know 表示“据我所知”,符合句意.所以选择B.

答案：B

规律点拨

as...as...是高考中的常考题型,要注意as...as...结构的拓展意义:as well as和,与……一样好; as far as远达,就……而言; as long as和……一样长,只要; as many/much as和……一样多,多达; as good as和……一样好,几乎等于.

【例10】He came to visit me and his smile on the face ______ that he was very pleased to see me.

A.insisted

B.described

C.declared

D.suggested

解析：根据题意“他脸上的笑容表明他见到我很高兴”,此处为“表明,暗示”,后面的宾语从句不使用虚拟语气.

答案：D

规律点拨

suggest表示“建议”时,后面跟虚拟语气,和insist一样表示一种“看法、说法”,后面的宾语从句使用陈述语气和相应的时态,意思为“表明,暗示”.
