參考答案：
　　1． D[解析]rough意為粗糙的、艱苦的，rough time指困難時(shí)刻，與difficult time意思一樣。long意為長(zhǎng)的；short意為短的；happy意為幸福的，與rough意義相反。
　　2． C[解析]give up是"放棄"的意思。如：In view of the circumstances，we should giveup the plan．考慮到情況的變化，我們應(yīng)該放棄這項(xiàng)計(jì)劃。abandon也是"放棄"的意思。如： After the age of about thirty he abandoned individual ambition．他一過三十就放棄了個(gè)人的雄心壯志。lost的意思是丟失；create意為創(chuàng)造；take意為拿。
　　3． D [解析]concrete意為具體的，它的同義詞是specific。如：In painting art，the expressed most specific theme and image is often the most abstract thinking．在繪畫藝術(shù)中，體的主題和形象所表達(dá)的往往是最抽象的思想。special的意思是特殊的；good，好的；real，真的。
　　4． A[解析]convert的意思是轉(zhuǎn)變、改變，change也是"改變"的意思。drop的意思是掉下、落下，而短語drop in意為順便走訪，如：Can you drop in at my office?你能順便到我辦公室來一下嗎?reduce是"減少"的意思；leave的意思是離開。
　5．C[解析]identify是"識(shí)別、認(rèn)出"的意思。如：We must also identify and nurture newtalent．我們也必須識(shí)別和培養(yǎng)新的人才。recognize也是"認(rèn)出"的意思。discover指發(fā)現(xiàn)，如： Columbus was one of the first Europeans to discover North America．哥倫布是最早發(fā)現(xiàn)北美洲的歐洲人之一。touch，觸摸；miss，錯(cuò)過、想念。
