1.答案:C
参考译文:知道有相当多的流行的英语表达来自圣经是有好处的。

题目分析:本句的语法结构比较简单,前半部分是固定句型,It’s good to do sth.做...是有好处的.后半部分为know引导的宾语从句.
考点讲解:
由题干可知,要求所填的动词可以和from搭配,由此可以直接排除及物动词acquire和obtain,derive from 由...起源,result from 因..引起,由词义可知选C.derive from为四六级考试中常考的词汇.
注意:要区别acquire和obtain当表示获得词义时的区别.acquire表示用于通过不断的学,问等慢慢地获取学问,技术等较抽象的事物.obtain表示经过相当长的时间或经过很大的努力,获得期望已久的东西.
2.答案:B
参考译文:Tom，你是否曾经想过会因为考试作弊受到处罚了吗
题目分析:本题主要考查了一个固定搭配it occurs to sb. that...，意思为某人想起了...,本题的题干为该固定搭配的一般疑问形式。

从句部分的结构比较简单。

考点解析：
根据题干所填空前的it以及后面的to you，可以排除happen，reflect以及strike。

需要注意的是，happen和strike均有比较类似的结构。

happen：it happened that...意为碰巧...或发生...
strike：it strikes sb. that...(=it occurs to sb. that...)意为使某人忽然想起...
本题所涉及的三个固定搭配希望大家能够牢记,尤其要注意其细微差别。

3.答案:D
参考译文:在美国，88%的吸烟者在十八之前就开始吸烟了，尽管出售香烟给18岁以下的人是不合法的
题目分析,前半句In the U.S. 88 percent of smokers had started before they were 18,句子的主干部分为88 percent of smokers had started,In the U.S.和before they were 18均为状语.注意后半句the fact that it is illegal to sell cigarettes to anyone under that age.为同为语从句,而不是定语从句.
考点解析
关于liable,注意liable的两个搭配,be liable for 对...有责任,be liable to 易于...
irrational 由否定前缀ir与rational构成.rational意思为理性的,理智的;合理的.另外在此处需要辨析rational和reasonable词义上的区别,rational指理性的,区别于动物无理性
的(irrational),指理智的,区别于感情用事的(emotional).reasonable指(人)讲道理的或(事物)有道理的,公平合理的.
illegal为否定前缀il与legal构成.legal意思为法律(上)的;合法的,法定的.
4.答案:A
参考译文:根据重要目击者的描述，特别大的鼻子是这个犯人面部的最令人难忘的特征。

题目解析:本题结构比较简单,a peculiarly big nose is the criminal’s most memorable facial feature.为主句,According to the key witnesses为状语。

考点解析:
本题主要是对四个选项的词义的辨析.feature意思为特征,原指面貌等显著的部分,用以指心中所留印象的显著部分.注意与characteristic相区别,characteristic意为特征,指与他物区别的特征.
注意:1,hint两个搭配，give/drop sb. a hint给人暗示;take a hint会意.
2,signature与sign词义的区别：sign作名词时意为符号,记号,姿势,手势,标识,牌示,征兆,迹象;signature的意思为签字，签名.
5.答案:B
参考译文:巴西的宪法规定军队禁止使用核能。

题目解析:本题题干为一简单句。

考点解析:
此题也是四个选项词义的辨析。

从上文constitution(宪法)可知，下文的the military use of nuclear energy是其所禁止的，所以选forbids
注意:当表示禁止，阻止意思时，可以表示为
stop/prevent/hinder/prohibit/restrain+from doing sth.
而forbid的用法为:forbid sb. to do sth.或forbid sb. sth.
object的用法为:object to doing sth.(to为介词).
