参考答案

1.D)

考查近义动词的语义及搭配用法。各选项的意思及用法是：选项A)separate使分开，区分，区别，常用结构是“separate A from B”。如：separate cause from effect区分因果关系;选项B)isolate使隔离，使孤立，常用于isolate…from结构中。如：Several towns have been isolated from the outside world by the flood.有好几个城镇因洪水与外界隔绝了。选项C)contrast对比，对照，常用于“contrast A with B”结构中。如：contrast Europe with America 将欧美两洲做一番比较;选项D)distinguish区分，辨别，常用于“distinguish A from B/distinguish between A and B”结构中。如：distinguish between right and wrong/distinguish right from wrong明辨是非。根据题干中的介词及句意，可判断出选项D)应为正确答案。全句意思为“众所周知，色盲的人很难区分红色与绿色”。

2.A)

考查副词语义。各选项的意思分别是：选项A)exceedingly非常地，十分地;选项B)excessively过分地，过多地;选项C)extensively 广阔地，广大地，广泛地;选项D)exclusively独有地，独享地;排斥地。根据题意，不难判断出选项A)应为正确答案。全句意思是“你的建议对他将非常有价值，他现在已智穷计尽”。

3.A)

考查易混动词的语义及搭配用法。除透项D)direct(把……对准，针对)以外，其余均表示“集中”的意思，均可和介词on搭配。除常规意思外，这三个单词还有一些特殊意义。选项A)concentrate聚集，集结，如：Birds concentrate in places where food is abundant.鸟类聚集在食物丰富的地方。选项B)focus聚集;聚焦于，如：All the eyes are focused on him.所有的眼睛都注视着他。选项C)renter 集中于，如：His interests are centered around his family.他关心的事情全离不开他的家庭。根据题意可知选项A)为正确答案。全句的意思为“政府已计划把新的工业集中建在高失业率区”。

4.C)

考查形容词语义。各选项的意思是：选项A)resistant抵制的，抵抗的;选项B)intense强烈的，剧烈的;选项C)urgent紧急的，紧要的;选项D)instant立即的，即刻的。根据题意可判断选项C)应为正确答案。全句的意思为“由于问题极其紧急，我们立刻进行了处理”。

5.A)

考查名词的语义辨析。根据句意可判断这儿应填入表示“范围，程度”意思的词，由此可排除选项B)rank(职衔;地位，社会阶层)和选项D)limit(限度，限制)。选项C)range表示“变动范围，变化幅度”，如：The speech covered a wide range of topics.这次演讲涵盖了一系列话题。The subject is outside my range.这个题目超出我所学范围。显然选项C)不符合句意。选项A) scale规模，程度，大小，如：They are preparing for war on：large scale.他们正在为战争做大规模的准备。从原文来看，选项A)scale符合题意。全句的意思是“当上层领导试图掩盖流行病的规模并轻视其影响时灾难变得更加严重了”。
