范例探究
【例1】If anyone happens to drop in while I am out,______ him or her leave a message. A.have B.get C.ask D.tell
解析：have后面接不带 to的不定式作宾语补足语,have sb.do sth. 让某人做某事.get,ask 和tell都后接带 to的不定式作宾语补足语. 答案：A
规律点拨
have sb.doing sth. 让某人做某事,让某种情况发生;have sb.do sth.使、让、叫某人干某事;have sth. done 请某人把某事做好;have sth. to do有事要做.
【例2】I have lost one of my gloves.I _____ it somewhere. A.must drop
B.must have dropped C.must be dropping
D.must have been dropped
解析：首先考虑主动,因为已经丢失,属于过去事实,从而推测过去一定丢在某处. 答案：B
规律点拨
对过去发生的事情推测,其肯定形式为must have done,may/might have done,但是must have done比另外两个语气强烈得多,表示特别有把握的推测,而其他表示“或许”,没有把握.
【例3】Do you remember one afternoon ten years ago ______ I came to your house and borrowed a necklace of yours? A.that B.which C.what D.when 解析：首先要知道ten years ago为插入语,解题时结合定语从句用法和插入语可以忽略原则判断应选D项. 答案：D
规律点拨
当引导定语从句的关系词与先行词之间有其他词组相隔时,我们称之为分割式定语从句,这种题型是高考的热点,判断这类定语从句关键是先将插入语忽略不计,然后找准先行词,从而顺利解题.
【例4】—I was riding along the street and all of a sudden,a car cut in and knocked me down. —You can never be ______ careful in the street. A.much B.very C.so D.too
解析：can not...too,can never...too意思为“怎么……也不为过”或者“越……越好”,表示肯定意义.
答案：D
规律点拨
用too表示肯定意义的有： (1)too...not to句式
(2)too...to句式(too后面接ready,inclined,apt等形容词或者前面有否定词)
(3)only too...to句式(too后为表示愉快心情的形容词,如:glad,pleased,willing等)
【例5】Helen was much kinder to her youngest son than to others,_____ of course,made the others envy him. A.who B.that C.what D.which 解析：从句子成分分析,本题考查的是非限制性定语从句的引导词;从题意看,引导词指代的是前面整个主句的意思:Helen对小儿子比对待其他人更好. 答案：D
规律点拨
引导非限制性定语从句时,which在定语从句中既可以作主语(不可以省略),也可以作宾语(可以省略);可以指代主句中的某个部分,也可以指代整个主句的内容.
【例6】On hearing the news of the accident in the coal mine,she _____ pale. A.got B.changed C.went
D.appeared
解析：本题考查系动词的用法.根据题意:她听到煤矿里发生事故的消息,脸一下子变得苍白.get,go均可以用作连系动词,表示变化,go表示“变得(不好、不妙等)”,符合题意;而appear用作系动词意思是“看上去似乎(而实际并非如此)”,不合题意.change不能用作连系动词. 答案：C
规律点拨
连系动词有两类;一是be,一是由行为动词转化而来的:look, seem, appear, taste, smell, sound,become,grow,turn,fall,run,prove,remain,lie等.如： The weather turned out fine.
His knowledge of English remains to be weak. It feels like glass.
【例7】 There’s _______ cooking oil left in the house.Would you go to the corner store and get _______. A.little;some B.little;any C.a little;some D.a little;any
解析：本题考查具体语境中的代词用法.由题意可知,第一个空需要否定意义的词,排除C、 D两项;第二个空表示肯定意义,排除B项. 答案：A
规律点拨
做这类题目的关键是要看清题意,明确代词使用的场合,具体表示什么意义.如:Sometimes Miss Li lets her favorite student do little jobs for her.本句中的little 却相当于small,是指老师让她的学生替她做点力所能及的小事情.
【例8】Stand over there ______ you’ll be able to see it better. A.or B.while C.but D.and
解析：本题考查固定句型结构“祈使句+and + 陈述句(一般将来时)”.句首出现动词原型可以判断该句是祈使句,而空格前后的意思顺承一致,含有因果意味,所以使用and.祈使句相当于一个条件句,and之后的陈述句表达结果. 答案：D
规律点拨
解答这类题目要掌握固定句型,并明确句子的意思.若意思逆反,则连词用or,副词用otherwise.如:Hold the handle tightly,or/otherwise you’ll fall off the motorbike.(抓紧把手,不然的话,你会从摩托上掉下来.)
【例9】 Sarah,hurry up.I’m afraid you wouldn’t have time to ______ before the party. A.get changed B.get change C.get changing D.get to change
解析：get changed是被动语态的另一种形式,相当于 be changed. 答案：A
规律点拨
在考试中考生往往对这类试题比较陌生,但是get +done是常用形式,如:get lost,get separated,get missed,get burnt,get paid,get burnt,get caught,get hurt等. 【例10】—Shall I give you a ride as you live so far away? —Thank you._______. A.It couldn’t be better B.Of course you can C.If you like D.It’s up to you
解析：根据回答中的“谢谢”可以推断回答为高兴的语气,It couldn’t be better再好不过了. 答案：A
规律点拨
这是一种特殊句式,为比较级的否定形式,形式是比较级,意义是最高级.另外,can’t...enough与can’t...too...也是用否定形式表示肯定意义.
