28、厲害，我必須找個醫(yī)生咨詢一下。consult咨詢，請教，商量。 6．A　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。 7．C　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。combine…with…把……和……結(jié)合起來。 8．A　考查固定搭配。on a diet 節(jié)食。 9．B　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。 10．B　考查動詞短語辨析。throw away 扔掉； put away 收起來； g

30、ave sth to do 有某事要做； 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。 15．A　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。 Ⅱ.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。 16．D　細節(jié)理解題。根據(jù)Buried with e-mails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。 17．D　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。 18．C　細節(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的設(shè)備。 19．C　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。 Ⅲ.20～24　CBGEF
