3、2018北京，12)A.need B.shouldC.can D.must答案C解析根據(jù)句意可知應(yīng)該選C項(xiàng)。can在此表示可能性，意為“可能，會(huì)”。need需要；should應(yīng)該；must必須，以上三者均不符合句意。句意為：在如今這個(gè)信息時(shí)代，數(shù)據(jù)的丟失可能會(huì)給一個(gè)公司帶來嚴(yán)重的問題。4.They might have found a better hotel if they a few more kilometers.(2018北京，13)A.drove B.would driveC.were to drive D.had driven答案D解析根據(jù)主句的謂語形式以及語境可知，if條件句應(yīng)該

4、用過去完成時(shí)，表示與過去事實(shí)相反的虛擬語氣。與過去事實(shí)相反的虛擬語氣的結(jié)構(gòu)：主句謂語用“should/would/could/mighthave done”，從句謂語用“had過去分詞”。5.I cant find my purse.I it in the supermarket yesterday，but Im not sure.(2018天津，10)A.should leave B.must have leftC.might leave D.could have left答案D解析句意為：我找不到我的錢包了。我昨天可能把它落在了超市里，但我不確定。根據(jù)句中的時(shí)間狀語yesterday可知空

5、格處是對(duì)過去發(fā)生事情的推測，需用“情態(tài)動(dòng)詞have done”，B、D兩項(xiàng)符合；再根據(jù)句中的but Im not sure排除B項(xiàng)“一定落在”，故選D項(xiàng)。若C項(xiàng)改為might have left，也是正確的。6.If we the flight yesterday，we would be enjoying our holiday on the beach now.(2018天津，15)A.had caught B.caughtC.have caught D.would catch答案A解析句意為：如果我們昨天趕上了航班的話，我們現(xiàn)在就在海灘上享受假期了。根據(jù)前半句中的時(shí)間狀語yesterday

6、以及后半部分中的would be enjoying及時(shí)間狀語now可知，這是一個(gè)錯(cuò)綜時(shí)間條件句。從句表示與過去事實(shí)相反的假設(shè)，故用“had動(dòng)詞的過去分詞”。7.Do you have Bettys phone number?Yes.Otherwise，I able to reach her yesterday.(2017天津，15)A.hadnt been B.wouldnt have beenC.werent D.wouldnt be答案B解析句意為：你有貝蒂的電話號(hào)碼嗎？有。不然我昨天就聯(lián)系不上她了。由空前的otherwise及句意可知應(yīng)用虛擬語氣，此處表示與過去事實(shí)相反的情況，謂語動(dòng)詞用

8、,7,8解題方法方法1意義判斷法所謂意義判斷法就是分析語境并確定應(yīng)填情態(tài)動(dòng)詞的含義。因此熟練掌握每個(gè)情態(tài)動(dòng)詞的意義和用法是做題的前提。方法2句型判斷法有些情態(tài)動(dòng)詞需要用在特定的句型中，如may表示推測時(shí)，往往用在肯定或否定句中；must表示推測時(shí)只能用于肯定句中。運(yùn)用此法就是通過分析所給句子的句型特點(diǎn)，選用具有特定句型特點(diǎn)的情態(tài)動(dòng)詞。方法3語氣判斷法情態(tài)動(dòng)詞主要表示說話人的語氣、情感或態(tài)度，所以在解答此類試題時(shí)，一定要注意說話者的語氣(這也是解題的難點(diǎn))，這就要求正確理解句子，從說話者的角度去考慮問題，結(jié)合具體的語境來分析和判斷，最后確定所需情態(tài)動(dòng)詞是否符合特定的情感需要。方法4人稱判斷法有些

9、情態(tài)動(dòng)詞在表達(dá)某個(gè)意義時(shí)，要與特定的人稱連用，這為我們選擇正確答案提供了方向。方法5特定詞匯、句型提示法虛擬語氣可以用在狀語從句、名詞性從句、定語從句中，在不同的從句中，虛擬語氣用不同的動(dòng)詞形式來體現(xiàn)，如if非真實(shí)條件句(分三種情形)，wish后的賓語從句等。所以，掌握了各類從句中虛擬語氣的動(dòng)詞形式，就基本上掌握了虛擬語氣的用法。另外，某些詞、句如if it were not for/had not been for，but for.，if only.，without等，往往也要采用虛擬語氣?？键c(diǎn)1情態(tài)動(dòng)詞的基本用法 1.My book，The House of Hades，is missin
