55.Withoutyourhelp,I＿＿＿＿theexamlastterm.

A.failedinB.wouldhavefailed

C.wouldn’tpassD.wouldfail參考答案及解析

1.C。will在此表示“應(yīng)諾”。

2.B。MayI...?中的may用以表示“允許、許可”。

3.A。shall用于第二、三人稱的肯定句或否定句，表示說(shuō)話人的意愿，有“命令、警告、威脅、強(qiáng)制、允諾、決心”之意。

4.C。may表示“允許”?；卮餸ay引起的問(wèn)句，肯定式一般用Yes,ofcourse.／Yes,certainly.／Sure.／Yes,youmay.否定式用No,youmustn’t.

5.A。needn’t表示“不必要”；mustn’t表示“禁止”；wouldn’t表示“拒絕”。

6.A。can表示“可能性”，通常用于否定句或疑問(wèn)句中，且有時(shí)還帶有“驚奇、不相信”等感情色彩。

7.B。must表示說(shuō)話人的主觀愿望，而haveto多表示客觀需要。

8.D。wouldhavedone表示對(duì)過(guò)去已發(fā)生的事情的推測(cè)，表示“可能……”。

9.B。shouldn’thavedone表示“過(guò)去本來(lái)不應(yīng)該做某事而事實(shí)上已經(jīng)做了”。

10.D。should／shouldnot＋do，表示“（現(xiàn)在）應(yīng)該／不應(yīng)該……”。

11.B。Let’sdosth.表示“建議做某事”，含聽(tīng)話一方在內(nèi)，故用shallwe。如果用Letusdosth.結(jié)構(gòu)，則用willyou?表示請(qǐng)求對(duì)方允許。

12.A。情態(tài)動(dòng)詞dare的過(guò)去式為dared，常用于否定句、疑問(wèn)句及條件句中，沒(méi)有人稱和數(shù)的變化，否定式是在dare后接not，再接動(dòng)詞原形。dare作為實(shí)義動(dòng)詞時(shí)，有人稱和數(shù)的變化，構(gòu)成否定句時(shí)，前要加助動(dòng)詞，后接帶to或不帶to的動(dòng)詞不定式。13.D。need作為情態(tài)動(dòng)詞，一般用于否定句、疑問(wèn)句及條件句中，后接動(dòng)詞原形。表示“現(xiàn)在不必干某事”,用neednotdosth.；表示“過(guò)去不必干某事”，用neednothavedone。need作為實(shí)義動(dòng)詞,與其它動(dòng)詞用法相同，用于否定句或疑問(wèn)句要加助動(dòng)詞。

14.C。“musthavedone”結(jié)構(gòu)，表示對(duì)過(guò)去發(fā)生情況的肯定推測(cè)。

15.B。can’thavedone，表示對(duì)過(guò)去發(fā)生情況的否定推測(cè)，意為“不可能已經(jīng)……”。

16.B。musthavedone表示對(duì)過(guò)去發(fā)生情況的肯定推測(cè)，句中帶有明確的過(guò)去時(shí)間狀語(yǔ)，故附加疑問(wèn)句用“didn’tthey”。17.C。should／ought
