(2007梅州二模)解析：結(jié)合前段內(nèi)容，特別是the的提示，可知要用bad的最高級(jí)worst，表示“最嚴(yán)重的”。如：[例41]…there was a lot of information about the city’s wellknown tourist ___34___ (attract)… (2008年廣州一模)解析：盡管attract是動(dòng)詞，但這是考查詞類(lèi)轉(zhuǎn)換的；在句中作介詞about的賓語(yǔ)，用名詞，故填attraction。[例40] Your mistake caused a lot of ________ (necessary) work in the office.解析：在名詞前作定語(yǔ)，仍用形容詞形式；但根據(jù)句意可知，錯(cuò)誤是引起不必要的麻煩事，故填unnecessary。技巧14：括號(hào)中所給詞有可能是要求詞義轉(zhuǎn)換，詞類(lèi)不一定要變，主要是考查具有與詞根意義相反的派生詞，需根據(jù)句子意思及前后邏輯關(guān)系，在詞根前加un—, im—等，在詞根后加—less等。[例37] There must be something ___40___ (serious) wrong with our society. (2008潮州期末)解析：要求填的詞修飾形容詞wrong，作狀語(yǔ)，用副詞，故填seriously。如：[例36] [例35] With the large numbers of students, the ________ (operate) of the system does involve a certain amount of activity.解析：在冠詞后，要用名詞，故填operation。技巧12：在形容詞性物主代詞后，或者在“冠詞(+形容詞)”后，用名詞形式。[例32] These people have made great ___39___ (contribute) to China with their work. (2007年茂名二模)解析：在句中作及物動(dòng)詞have made的賓語(yǔ)，要用名詞形式；表示“作貢獻(xiàn)”，其前面沒(méi)有不定冠詞時(shí)，習(xí)慣上用復(fù)數(shù)，故填contributions。技巧11：作主語(yǔ)、在及物動(dòng)詞或介詞后作賓語(yǔ)，用名詞形式。[例29] In a ________ (danger) part of the sea off the coast of New Zealand, they learnt to…解析：在冠詞與名詞之間，要用形容詞，作定語(yǔ)，故填dangerous。具體方法有：技巧10：作表語(yǔ)、定語(yǔ)或補(bǔ)語(yǔ)，通常用形容詞形式。[例27] Lessons ___39___ (learn) in sports can help us in our dealing with other people. (廣東考試說(shuō)明)解析：因句中已有謂語(yǔ)can help，所以learn應(yīng)為非謂語(yǔ)動(dòng)詞；又因lesson與learn是被動(dòng)關(guān)系，要用過(guò)去分詞短語(yǔ)作定語(yǔ)，故填learned。(4)不論非謂語(yǔ)動(dòng)詞在句中作何種成分，若判斷需要用分詞，與邏輯主語(yǔ)是主動(dòng)關(guān)系用—ing形式，是被動(dòng)關(guān)系用—ed形式。如：[例24] He saw the stone, ___37___ (say) to himself: “The night will be very dark.” (2008年?yáng)|莞一模)解析：句中已有謂語(yǔ)saw，所給動(dòng)詞與saw不是并列關(guān)系，應(yīng)當(dāng)是非謂語(yǔ)動(dòng)詞；又因He與say是主動(dòng)關(guān)系，故填saying作伴隨狀語(yǔ)。[例23] Some people say that oldest children, who are smart and strongwilled, are very likely ___33___ (succeed). (2008年佛山一模)解析：因在形容詞likely后作狀語(yǔ)，要用動(dòng)詞不定式，故填to succeed。(2)作目的狀語(yǔ)或者在形容詞后的作狀語(yǔ)，一般用不定式。如：[例20] …but it is not enough only ___35___(memorize) rules from a grammar book. (2007年佛山一模)解析：因it是形式主語(yǔ)，后面用不定式作真正的主語(yǔ)，故填to memorize。技巧9：若句中已有謂語(yǔ)動(dòng)詞，又不是并列謂語(yǔ)時(shí)，所給動(dòng)詞就是非謂語(yǔ)動(dòng)詞。[例18] That was definitely not an attractive idea so I politely declined her Invitation, ___40___ (close) my book and walked away. (2008年廣州一模)解析：雖然句中已有謂語(yǔ)動(dòng)詞declined，但由and walked可知，所填詞與declined和walked是并列關(guān)系，所以也用一般過(guò)去式closed。技巧8：若句中沒(méi)有別的謂語(yǔ)動(dòng)詞，或者雖然已有謂語(yǔ)動(dòng)詞，但需填的動(dòng)詞與之是并列關(guān)系時(shí)，所給動(dòng)詞就是謂語(yǔ)動(dòng)詞；若是謂語(yǔ)動(dòng)詞，就要考慮時(shí)態(tài)語(yǔ)態(tài)。(2) 給出了動(dòng)詞的試題的解題技巧首先，判斷要填的
