第一节:单项填空(共15小题;每小题1分,满分15分)

  从每题所给的A、B、C、D四个选项中,选出可以填入空白处的最佳选项。

  1.Eating too much fat and sugar can ________ heart disease and high blood pressure.

  A.result from       B.attend to

  C.devote to D.contribute to

  解析:选D 句意:吃太多的脂肪和糖会引发心脏病和高血压。result from"产生,起因于";attend to"照料,处理";devote ... to"专心于";contribute to"引发"。故D项符合句意。

  2.The system has been designed to give students quick and easy________to the digital resources of the library.

  A.access B.passage

  C.way D.approach

  解析:选A 句意:新设计的系统能够让学生便捷、容易地搜索到图书馆的电子资源。这里give ... access to ...是固定词组,表示"能得到,能进入",所以选A。

  3.He delayed ________ her the news, waiting for the right moment.

  A.to tell B.telling

  C.to have told D.having told

  解析:选B 句意:他没有马上把消息告诉她,等待适当的时机再说。delay后接动名词而不跟不定式作宾语,可排除A、C两项;tell 并非发生在delay之前,可排除D项。

  4.(天津高考)It was not until near the end of the letter ________ she mentioned her own plan.

  A.that B.where

  C.why D.when

  解析:选A 句意:直到将近信的结尾她才提及了自己的计划。本题的题干为强调句型,被强调部分为not until near the end of the letter,故选A。

  5.We don't have enough books for ________; some of you will have to share.

  A.somebody B.anybody

  C.everybody D.nobody

  解析:选C 句意:我们没有足够的书给每一个人,你们中的一些人将不得不共用。根据后半句可知,此处应用everybody, everybody与not连用构成部分否定。
