　　考查近義動詞的語義及搭配用法。各選項的意思及用法是：選項A)separate使分開，區(qū)分，區(qū)別，常用結(jié)構(gòu)是“separate A from B”。如：separate cause from effect區(qū)分因果關(guān)系;選項B)isolate使隔離，使孤立，常用于isolate…from結(jié)構(gòu)中。如：Several towns have been isolated from the outside world by the flood.有好幾個城鎮(zhèn)因洪水與外界隔絕了。選項C)contrast對比，對照，常用于“contrast A with B”結(jié)構(gòu)中。如：contrast Europe with America將歐美兩洲做一番比較;選項D)distinguish區(qū)分，辨別，常用于“distinguish A from B/distinguish between A and B”結(jié)構(gòu)中。如：distinguish between right and wrong/distinguish right from wrong明辨是非。根據(jù)題干中的介詞及句意，可判斷出選項D)應(yīng)為正確答案。全句意思為“眾所周知，色盲的人很難區(qū)分紅色與綠色”。

　　2.A)

　　考查副詞語義。各選項的意思分別是：選項A)exceedingly非常地，十分地;選項B)excessively過分地，過多地;選項C)extensively廣闊地，廣大地，廣泛地;選項D)exclusively獨有地，獨享地;排斥地。根據(jù)題意，不難判斷出選項A)應(yīng)為正確答案。全句意思是“你的建議對他將非常有價值，他現(xiàn)在已智窮計盡”。

　　3.A)

　　考查易混動詞的語義及搭配用法。除透項D)direct(把……對準(zhǔn)，針對)以外，其余均表示“集中”的意思，均可和介詞on搭配。除常規(guī)意思外，這三個單詞還有一些特殊意義。選項A)concentrate聚集，集結(jié)，如：Birds concentrate in places where food is abundant.鳥類聚集在食物豐富的地方。選項B)focus聚集;聚焦于，如：All the eyes are focused on him.所有的眼睛都注視著他。選項C)renter集中于，如：His interests are centered around his family.他關(guān)心的事情全離不開他的家庭。根據(jù)題意可知選項A)為正確答案。全句的意思為“政府已計劃把新的工業(yè)集中建在高失業(yè)率區(qū)”。

　　4.C)

　　考查形容詞語義。各選項的意思是：選項A)resistant抵制的，抵抗的;選項B)intense強烈的，劇烈的;選項C)urgent緊急的，緊要的;選項D)instant立即的，即刻的。根據(jù)題意可判斷選項C)應(yīng)為正確答案。全句的意思為“由于問題極其緊急，我們立刻進行了處理”。

　　考查名詞的語義辨析。根據(jù)句意可判斷這兒應(yīng)填入表示“范圍，程度”意思的詞，由此可排除選項B)rank(職銜;地位，社會階層)和選項D)limit(限度，限制)。選項C)range表示“變動范圍，變化幅度”，如：The speech covered a wide range of topics.這次演講涵蓋了一系列話題。The subject is outside my range.這個題目超出我所學(xué)范圍。顯然選項C)不符合句意。選項A) scale規(guī)模，程度，大小，如：They are preparing for war on：large scale.他們正在為戰(zhàn)爭做大規(guī)模的準(zhǔn)備。從原文來看，選項A)scale符合題意。全句的意思是“當(dāng)上層領(lǐng)導(dǎo)試圖掩蓋流行病的規(guī)模并輕視其影響時災(zāi)難變得更加嚴(yán)重了”。
