    1．The population of this city, forty percent of which 15% in the last three years. A. are Germans; has risen by B. are Germen; has fallen by C. is Germans; have increased to D. are Germans; have been reduced by 分析:本题旨在考查本单元的词汇population的用法以及主谓一致.population强调人口是多少时.若作主语.谓语动词用单数形式.population强调人口的身份或特征.若后面作表语的名词是复数时.谓语动词则要用复数形式.据题意.第一空中Germans 用复数.则谓语动词用复数.B.C两项可排除.而the population of this city强调人口.谓语动词需用单数.故本题最佳答案为A. 2．You will be late you leave immediately. A. unless B. until C. if D. or 解析:本题考查连词的用法.unless"除非......".与本题中"除非立刻就去.不然你会迟到的"意义相符.而until"直到......才......"常表示延续动作或状态直到某时结束.or表示"或者""否则".如选D.原题应为leave immediately, or you will be late,这属于另一种句型.故选A. 3． him and then try to copy what he does. A. Mind B. Glance at C. Stare at D. Watch 解析:本题考查动词的辨析.本句句意是"先仔细观察.然后照他那样去做".mind"介意.在乎".glance at"粗略的看",stare at "盯着.凝视",watch"观察.观赏".因而不难选出答案.答案选D. 4．I can hardly hear the radio, would you please ? A. turn it on B. turn it down C. turn it up D. turn it off 解析:本题考查动词词组的辨义.题中的信息是"收音机声音太低.听不清楚".故可知应"调大音量".A项为"打开".B项为"把......调低".C项为"把......调高".D项为"关闭".故选C. 5．The boy wanted to ride his bicycle in the street, but his mother told him . A. not to B. not to do C. not do it D. do not to 解析:本题考查不定式作宾补的用法.事实上是直接引语转为间接引语的用法.本题理解为The boy's mother said "Don't ride in the street",转为间接引语后为:The boy's mother told him not to ride in the street. 然后再根据英语中避免重复的原则,将前面出现的ride in the street省略.选出答案A. 【查看更多】
