“特殊疑问词+动词不定式”的用法归纳
一.由两部分构成:
疑问词和动词不定式(wh-+todo)。
疑问词部分包括疑问代词who,whom,what,which和whose以及疑问副词when,where和how。
此外,连接词“whether”也适用.它主要具有以下几种功能:
⑴当主语,如:
●Whentoholdthemeetinghasnotyetbeendecided.
●Wheretoliveisaproblem.
⑵当宾语,常接在forget,findout,discuss,decide,tell,teach,know,learn,wonder,remember等动词之后作宾语如:
●Wemustknowwhattosayatameeting.
●Hecouldnottellwhomtotrust.
●Doyouknowhowtoplaybridge?
⑶当表语,如:
●Theproblemiswheretofindthefinancialaid.
●Thequestioniswhotoelect.
⑷当名词同位语,如:
●Tomhadnoideawhichbooktoreadfirst.
●Thequestionwhethertoconfesstroubledthegirl.
⑸用于宾语补足语,双重宾语。
某些动词后可接“sb.+疑问词+不定式”构成的双重宾语,这类动词常用的有advise,ask,show,teach,tell等如:
●Icantellyouwheretogetthisbook.
●IaskherhowtolearnEnglish.
●Hewilladviseyouwhattodo.
●Willyoushowmehowtousethemachine?
(6)作介词宾语:
某些介词后面可接"疑问词+不定式"作宾语,这类介词常用的有about,as,from,in,of,on,with等。
例如:
Hehasnoideaofhowtoanswerthisquestion.他不知道怎样回答这个问题。
Dellahadonly$1.87withwhichtobuyJimapresent.德拉仅有$1.87为来吉姆买一件礼物。
(which是关系代词)
Youhaveanumberoftopicsfromwhichtochoose.你有很多题目可以选择。
(which是关系代词)
二“特殊疑问词+动词不定式”这种结构可以把复合句转为简单句。
如:
Idon’tknowwhatI’lldonext.=Idon’tknowwhattodonext.
Thedoctortoldhimwhenheshouldtakethemedicine.=Thedoctortoldhimwhentotakethemedicine.
同样,因为“特殊疑问词+动词不定式”这种结构相当于一个名词性从句,所以可用同等成分的从句代替,从而把简单句转换为复合句。
改写时只需在疑问词后加上适当的主语,并把不定式改为适当的形式的谓语即可。
如:
Whichtochooseisimportant.=Whichweshouldchooseisimportant.
Thequestioniswheretogo.=Thequestioniswhereweshouldgo.
三、“特殊疑问词+动词不定式”这种结构可构成独立问句。
如:
Whattodo?
怎么办?
Howtogetridofthetrouble?
如何摆脱困境?
按照英语语法的习惯,疑问副词why 后不直接跟动词不定式,如:
误:
Idon’tknowwhytochoosethatdictionary.
正:
Idon’tknowwhyyoumustchoosethatdictionary.
但它可以接不带to的动词不定式,即动词原形,构成whydosth./whynotdosth.肯定形式是表示某动作是不必要的或没有意义的,而否定形式是表示向某人提建议和表达看法,相当于祈使句。
TodayisSunday.Whynotgoouttorelaxyourself?
Whypaymoreatothershops?
Wehavethebestvalue.
