25、before既可作介詞(后接名詞或代詞)、連詞(后接句子)也可作副詞(不接句子成分)，通常用于一般過去時的句子中。shortly after意為“之后不久”。very fast意為“很快”，主要指速度上的快。3A考查非謂語動詞。此題中使役動詞get后接的賓語car與作賓語補(bǔ)足語的動詞wash之間為被動關(guān)系，構(gòu)成短語：get sth done。故答案選A。句意：在驅(qū)車進(jìn)城之前，你必須將你的車洗了。4B考查動詞辨析。句意：如果我們想要獲得成功，知識和學(xué)習(xí)很重要。但是它們或許會限制我們的思維。direct指示， 指引，導(dǎo)演(戲劇或電影)；指揮(管弦樂隊)；limit限制；change改變；impro

26、ve改進(jìn)，改善。根據(jù)句中but的轉(zhuǎn)折，選B。5A句意：我頭痛得很厲害，我必須找個醫(yī)生咨詢一下。consult咨詢，請教，商量。6A考查省略用法。在含有ought to句子的簡略回答中， 表示過去動作的have不能省略。7C考查動詞辨析。句意：如果他能把自己的才能和勤奮結(jié)合起來，必定會很成功。combinewith把和結(jié)合起來。8A考查固定搭配。on a diet 節(jié)食。9B考查動詞短語辨析。get away with 逃脫懲罰。make use of 利用；get rid of 除掉；end up with 以而告終。10B考查動詞短語辨析。throw away 扔掉； put away 收起

27、來； give away 泄露(秘密)，捐獻(xiàn)； carry away 拿走。11D考查動詞短語辨析。cut down 削減。 cut up 切碎； cut off 切斷；cut out 切除。12A句意：眾所周知，邁克相當(dāng)清楚他自己的優(yōu)缺點(diǎn)。strength強(qiáng)項，長處，與weakness相對應(yīng)。value價值；technique技術(shù)；energy精力，能量。13B考查形容詞辨析。句意：你對她所做的事情感到滿意嗎？非常滿意，她做得再好不過了。 not a little 非常，所以下文應(yīng)是“她做得再好不過了”。 better 與 not 連用表示最高級含義。14Bhave sth to do 有某

28、事要做； have sth done 讓別人做某事。句意：即將到來的周末我有很多事要完成，因此我抽不出時間休息。故選B。15A句意：越來越多的中國人已經(jīng)意識到他們應(yīng)該均衡飲食，每天鍛煉身體。diet是可數(shù)名詞，表示泛指要用不定冠詞a，go on a diet表示“節(jié)食”。do exercise鍛煉身體，exercise前不用冠詞。.白領(lǐng)是令人羨慕的一族，可是他們也有苦惱，與工作無關(guān)的海量信息讓他們苦不堪言。16D細(xì)節(jié)理解題。根據(jù)Buried with emails中的最后一句可知一些白領(lǐng)每天要閱讀至少100封電子郵件。17D推理判斷題。Bothered with calls中的最后一句提到員工可能要放下更加重要的工作來處理電話事務(wù)，由此可推斷打電話可能會導(dǎo)致工作程序的改變。18C細(xì)節(jié)理解題。根據(jù)文章最后一段前半部分中的內(nèi)容可知一些公司解決問題的辦法是為員工提供更加先進(jìn)的設(shè)備。19C主旨大意題。本文是一篇調(diào)查報道，結(jié)合全文尤其是文章第一段的內(nèi)容可知本文的主要內(nèi)容是白領(lǐng)深受信息泛濫之苦。.2024CBGEF
