10、.wait for的意思为等待,等候.其它两个介词与wait不构成词组.2,语境题.本句的意思为这个闹钟,叫做sleepsmart,测量你的睡眠周期,并等待你进入你睡眠的最轻的阶段,叫醒你_.分析该句话后可知,本句是讲这个闹钟的作用,由常理可知,必然是在闹钟叫醒你之前.所以应该选before.3,词汇搭配题.本题主要是考察意思比较相近的词汇的辨析.第一组是ensure和assure.ensure意为确保某种行动或动因的结果一定会发生,常用句型为ensure that.保证.,ensure sb.sth.保证某人得到某物.assure指以十分肯定的语气向别人保证,某事一定会发生.第二组是requ

11、ire和request,这两个词都有要求的意思， 但是require与request的区别就在于前者还可表示客观上的需求，比如说building requires woods.而request只能表示主观上的要求，不能表达客观上的需求.由此分析可知正确答案为ensure.意思为它确保你睡醒时感觉神清气爽.4,词汇搭配题.本题考查动词pass与介词构成的词组的意思的辨析.pass through的意思为通过,经过,穿过;经历.pass into的意思为进入.pass on的意思为去世,传递.pass about无此搭配.由此可知应该选择through.这句话的意思为当你睡着时,你经历一个睡眠状态

12、的顺序-轻度睡眠,深度睡眠,rem睡眠.5,语境题.本题的解答有赖于对前一句话的理解.注意到前一句中的a sequence of sleep states,意思为一个睡眠状态的顺序,再结合本句的every 90 minutes.可以确定应该选择含有重复意思的repeat,即这个睡眠状态的顺序每九十分钟重复一次.6和7,语境题.对这两个空所在的句子进行深入分析:the point in that cycle at which you wake can _6_ how you feel later, and may _7_ have a greater impact than how much o

13、r little you have slept.首先用到我们之前讲到过的标志词法,找到and,and连接的是两个分句,我们知道and引导的两个句子只有可能是并列结构或者是递进结构.再分析第二个分句,明显是一个省略句,我们把第二句还原the point in that cycle at which you wake may _7_ have a greater impact than how much or little you have slept.注意到第二句中的a greater impact可知这两句话应该是递进的关系,即第一句讲某物有影响,第二句又讲有更大的影响.所以第一个空应该选择含

14、有影响意思的动词,即affect.又因为知道了两句话之间的递进关系,由此可以确定第七题应该选择表示递进关系的even,意思为甚至.8,词汇搭配题.选项四个词汇都是比较常见的,将选项四个词汇带入空格,可以很容易选出含有意味着意思的mean.我要说一下本题的另外一个作用,在完型填空中常会用到一种叫做复现结构的解题方法,也就是在上下文中重复的讲一件事.本句话讲在轻度睡眠时被叫醒意味着你被叫醒时会精力充沛.回想到第二题,可以很容易的验证应该是在叫醒你之前让你进入轻度睡眠状态.9和10,词汇搭配题.分析该句话sleepsmart _9_ the distinct pattern of brain wav

15、es _10_ during each phase of sleep,对前半部分,其主语为sleepsmart,宾语为the distinct pattern of brain waves,由此可确定应该选择记录意思的record.后半部分,由所填动词引导的部分在句中作定语,修饰the distinct pattern of brain waves,其意思为在在睡眠每一个阶段_的脑电波,由此可确定应该选择含有产生意思的produce.11,词汇搭配题.本题考查固定搭配equip with,意思为装备,配备.12和13,词汇搭配题.选项12主要考查固定搭配the same.as.,由句子some

16、 machines used for medical and research _13_,并考察四个选项,很容易选出含有目的意思的purpose.14,词汇搭配题.分析you _14_ the clock with the latest time的主谓宾,主语为you,宾语为the clock with the last time,所填入的动词做谓语,即你.闹钟,考察选项的四个词汇,program作动词时的意思为编制程序,在此处引申为调,即调闹钟.15,词汇搭配题.本题考查定语从句的先行词,由空格前的at,很容易选出which.16,语境题.本题实际上是考查两个句子之间的逻辑关系.分析句子yo

17、u _14_ the clock with the latest time at _15_ you want to be wakened, and it _16_ duly (适时地) wakes you during the last light sleep phase before that.前一句话的意思为你把闹钟调到你想要被叫醒的最近的时间,后一句话并且它可以在你所定的时间之前的一个轻度睡眠阶段叫醒你.由此可以确定两句话是递进关系,所以应该选择then.17,语境题,根据句中的invented并考察四个选项,可以确定应该选择concept,它指形成这个闹钟的这种想法.利用复现结构,看到

18、本文的最后一句a company created by the students to develop their idea.中的idea.18,语境题,本题主要是考察一个时间上的逻辑关系.前面讲闹钟这个想法被发明,后面讲一个朋友抱怨睡醒后很累并且测试的表现很不好.由此可判定闹钟的发明应该是在朋友的抱怨之后,即应该选择after.19和20,分析句子“_19_ sleep-deprived people ourselves, we started thinking of _20_ to do about it,”前半句话在句中作状语,关键是他到底做什么状语?由前半句中的ourselves,以及后半部分中的we,可以确定前半句话作方式状语,即用as引导的方式状语.本句话是对整个文章的一个总结,结合上下文,空格20应该选择what,整句话的意思为作为我们这些被剥夺睡眠的人,我们开始考虑关于它该做点什么了.翻译答案及解析:1,consider the quality of humans sleep.解析:本题考查consider一词的用法,2,one
