情態(tài)動(dòng)詞專項(xiàng)練習(xí)與解析一【練習(xí)解析】1．C從原題中Youcankeepittillnextweekifyoulike這一信息句可知，“你不必現(xiàn)在還”。2．D從原題中Whereismypen這一信息句可告訴考生，“筆丟了”，丟的動(dòng)作是過去發(fā)生的。因此用must+havedone表示對(duì)過去事實(shí)的肯定猜測。3．C原題中的yesterday這一信息詞告訴考生，在wish后的賓語從句中，用過去完成時(shí)，表示與過去事實(shí)相反的愿望。4．B從原題中的Ididn’thearthephone.這一信息可以判斷出，用musthavedone表示過去事實(shí)的準(zhǔn)確的肯定猜測。5．A從原題中l(wèi)astSaturday這一信息詞可知，條件句中用表示與過去事實(shí)相反的過去完成時(shí)，主句用would+havedone。6．Amighthave+過去分詞，在次是虛擬語氣，表示“本來可以給你更多的幫助”，而事實(shí)則是幫助較少。7．C從原題中的yesterday這一信息詞暗示考生，該句應(yīng)選用與過去事實(shí)相反的過去完成時(shí)，Ifithadnotbeenfor…“要不是因?yàn)椤薄?．D原題中的Withoutelectricity相當(dāng)于一個(gè)條件句：Iftherewerenoelectricity,故主句用humanlifewouldbequitedifficulttoday.9．Acan可以表示一種客觀上的能力，本句can’t，表示“不能，不會(huì)”。10．B從原題總的“Iwonderwhyshechangedhermind”“我不知道為何他改變了主意了?！边@句話告訴考生Janny沒有守諾言。因此，用should+havedone，表示“過去本應(yīng)該做某事，而實(shí)際上沒有做”。11．C可參看10題。意思是：“昨晚本應(yīng)該學(xué)習(xí)，但是卻去聽音樂會(huì)了?！?2．C原題中的could不是過去時(shí)，而表示一種委婉、客氣的禮貌用語。因此用could提問時(shí)，用can回答。同樣用would，might提問，用will和may回答。[注意]①—Wouldyouratherdosuchathing—Yes,Iwould.②—Wouldyoulikesometea—Yes,Iwould.這兩個(gè)對(duì)話中的wouldrather，wouldlike是慣用法，故不能用will來回答。因?yàn)樵谶@兩個(gè)句型中，will不能去替換would。13．A可參看10、15題。該句意思是：“湯姆本來不該告訴我你的秘密，但他沒有傷害你的意思?！眔ughtnottohavedone=shouldn’thavedone14．B從答語中的Luckilyhewassenttothehospitalimmediately這一信息句可提示考生，條件句應(yīng)填表示與過去事實(shí)相反的時(shí)態(tài)。15．B從原題中的butheisn’tverysureyet這一信息句可暗示考生，Peter當(dāng)晚來的可能性不大。A是“準(zhǔn)來，肯定來”，D是“將要來”。16．C可參看10、11、13題。“本應(yīng)該”而事實(shí)上沒有……17．D從原題中Ididn’tseeyoursisteratthemeeting和后文shewouldhavemetmybrother這兩個(gè)信息句可知，if條件句中應(yīng)填與過去事實(shí)相反的過去完成時(shí)?？蓞⒖?、7、14題。18．A你不必告訴他。因?yàn)镮’vetoldhimalready這一信息句已暗示考生了。19．C當(dāng)asif引導(dǎo)虛擬語氣的句子是，如果主句與從句中的謂語詞所表達(dá)的動(dòng)作同時(shí)發(fā)生時(shí)，asif后接一般過去時(shí)。例如：Hewalkedasifhewerelame.如果從句中的謂語動(dòng)作發(fā)生個(gè)在主句謂語動(dòng)作之前，則用過去完成時(shí)。例如：Hetalkedasifhehadknownthesecret.不論主句中的謂語是現(xiàn)在時(shí)還是過去時(shí)。20．C只要考生抓住nearly一詞和后文atanymoment（隨時(shí)的意思）這兩個(gè)信息詞語，就能很快選出C項(xiàng)，表示邏輯推測，意思是“快七點(diǎn)鐘了，杰克一會(huì)兒就該到了。”21．D根據(jù)句意，是對(duì)過去情況的推測?！爱?dāng)時(shí)決不可能是一次舒服的乘車?！眒ust表示對(duì)過去的推測只能用于肯定句。22．Bmustn’t表示“禁止”；may表示“有可能”。句子的意思是：“你不可以玩刀，可能會(huì)傷你自己。”23．D該題在考考生could與wasableto之間的區(qū)別。Wasableto表示在困難的情況下，經(jīng)過一番周折而“能……”，并且成功地做了。24．B該題考查情態(tài)動(dòng)詞should表推測的用法。Can和might都可以表示可能性，用might則語氣更加不肯定。Need表示“需要”、“必需”。Should可以表示推測，結(jié)合實(shí)際，合乎邏輯，意為“應(yīng)當(dāng)”、“該”。根據(jù)第一個(gè)說話者說的Ineedthemtomorrowafternoon的語境，可以確定正確答案為B。25．A該題在考查“情態(tài)動(dòng)詞+不定式的完成式”的用法，從會(huì)話的語境看，空白處應(yīng)填“could+have+過去分詞”表示過去本來能做到的事而事實(shí)上沒有做到。26．B該題考查表示請(qǐng)求的英語口語，用will來向第二人稱提問的疑問結(jié)構(gòu)，是表達(dá)一種意愿和請(qǐng)求，是以疑問的形式來表達(dá)較為婉轉(zhuǎn)的祈使語氣，意思是“請(qǐng)你……，好嗎”，對(duì)于這種問句的肯定答語可用Sure!Certainly!Yes,ofcourse.I’dbegladto等；否定回答通常是I’msorry,Ican’t.No,I’mafraidIcan’t.I’msorry,but…I‘dliketo,but…等。27．Dmight表示“可能性”。28．C意思是“我會(huì)的”。對(duì)祈使句的肯定回答。29．Bshouldn’thavedone為本來不該做某事，而事實(shí)上做了。30．D用maynot可表示“可能不”。而cannot則表示斷然的否定推測“不可能”。A，C意思不符。專項(xiàng)練習(xí)二答案與解析
