答案及解析：
1. 【解释】much more等于still more，意为“更不用说”，用于肯定句;much less也就是still less ,意思相同，但用于否定句。故答案为D。
2. 【解释】考查名词性从句。第二句话中what little he knows about it作整句话的主语，其中what用做little的定语，意思是“所……的一点点”。
3. 【解释】would(had) rather, would as soon, would sooner
或would prefer 所引导的从句中要求使用虚拟语气，另外，对过去
事实的虚拟应用过去完成时，所以选A。
4. 【解释】在以lest和for fear that引导的状语从句中，谓语动词多用虚拟语气，通常构成是：should +动词原形；本题用should+ have done的形式，表示动作发生在她“担心”这个动作之前并已完成。故答案为B。
5. 【解释】but用作连词时，不引导虚拟语气的句子，但可以同前半句是虚拟语气的句子连用。如果前半句是对过去事实的虚拟，but 后用一般过去时；如果是对现在事实的虚拟，but后用一般现在时。故答案为A。
大学英语四级考试语法：—定语从句
大学英语四级考试语法：—定语从句 很多同学在大学英语四级考试中会存在一些误区，认为语法不那么重要，其实英 语语法是学习英语的指南，对我们帮助很大。以下是小编给大家整理的大学英语四级 考试语法：—定语从句，希望可以帮到大家 1、mary is a beautiful girl. 名词的扩展靠限定，最基本的就是在名词的前面增加一个形容词这样的定语，上 面的句子就是表语girl的前面加了一个形容词。显然，如果只是mary is a girl这样的 句子会让人觉得非常枯燥，没有什么意义，所传递的信息量极其有限。所以，名词前 面加定语，可以使被限定的名词更加生动，更加形象而富有生命。如果要对名词给出 更多限定，挖掘更多内部信息，我们可以在名词前面加多个定语来限定，如mary is a beautiful chinese girl. 放在名词前面起到限定作用的定语有很多种形式，形容词，名词，动词现在分词，动词过去分词等。虽然形式多样，但是这类定语还是比较好理解，只要顺着句子的顺序，就基本可以明白是怎么回事。 2、the computer that i bought yesterday works well. 有时候，我们需要对名词给出很多的说明，用大量的信息来限定名词。这时，如 果还是把长长的限定成分放在名词前面，就会头重脚轻，所以英语中会用跟在名词后 面的定语从句来限定前面的名词。根据定语的功能还可以分为限制性定语从句和非限 制性定语从句。两者的区别在于前者与被限定名词之间没有逗号，而后者则有逗号隔开;前者起到限定作用，不可或缺，后者起到补充作用，舍去后对剩余部分影响不大。 本句子通过“that i bought yesterday”这个that引导的定语从句，使得主语the computer得到限定而明确，是我昨天买的计算机而不是别的。如果明白了这个名词可 以通过后面加定语从句来扩展，我们的句子马上可以变得复杂起来，请看下例：another popular spectator sport, which is known as the sport of kings, is horse-racing, which is controlled by the jockey club. 译文：另一种以特大型运动著称的流行观赏运动是赛马，这种比赛由赛马总会控制。

2016 年12 月大学英语四级考试真题及 答案 【篇一：2016 年12 月大学英语四级翻译作文题目及答 案】 翻译一： 在中国文化中，红色通常象征着好运、长寿和幸福。在春节和其他喜庆场合，红色到处可见。人们把现金作为礼物送给家人或亲密朋 友时，通常放在红信封里。红色在中国流行的另一个原因是人们把 它与中国革命和共产党相联系。然而，红色并不总是代表好运与快 乐。因为从前死者的名字常用红色书写，用红墨水写中国人名被看 成是一种冒犯行为。 as a symbol of good luck, longevity and happiness in chinese culture, the color of red can be seen everywhere during springfestive and other festive/ joyous occasions. cash is usually put in red envelopes as gifts for relatives and close/intimate friends. also, red is much-welcomed / fashionable in china because of its association with chinese revolutions and the communist party. however, red does not always represent / equal to good luck and joy. red was previously used to write the names of the deceased so it is seen as an offence to write chinese people ’s names in red ink. 翻译二 随着中国的改革开放，如今很多年轻人都喜欢举行西式婚礼。新娘 在婚礼上穿着白色婚纱，因为白色被认为是纯洁的象征。然而，在 中国传统文化中，白色经常是葬礼上使用的颜色。因此务必记住， 白花一定不要用作祝人康复的礼物，尤其不要送给老年人或危重病 人。同样，礼金也不能装在白色信封里，而要装在红色信封里。 with the reform and opening-up of china, a great many young people nowadays prefer to hold western-style wedding: the bride wears white wedding gown because the color is considered to symbolize purity/is considered as the symbol of purity. however, in tradition chinese culture, white is often used on funerals. so, do bear in mind that white flowers should never be used as a gift to celebrate someone ’s recovery, especially not for the aged or those who are seriously ill.

Colleges taking another look at value of merit-based aid Good grades and high tests scores still matter—a lot—to many colleges as they award financial aid. But with low-income students projected to make up an ever-larger share of the college-bound population in coming years, some schools are re-examining whether that aid, typically known as “merit aid”, is the most effective use of precious institutional dollars. George Washington University in Washington, D.C., for example, said last week that it would cut the value of its average merit scholarships by about one-third and reduce the number of recipients(接受者), pouring the savings, about $2.5 million, into need-based aid. Allegheny College in Meadville, Pa., made a similar decision three years ago. Now, Hamilton College in Clinton, N.Y., says it will phase out merit scholarships altogether. No current merit-aid recipients will lose their scholarships, but need-based aid alone will be awarded beginning with students entering in fall 2008. Not all colleges offer merit aid; generally, the more selective a school, the less likely it is to do so. Harvard and Princeton, for example, offer generous need-based packages, but many families who don’t meet need eligibility(资格)have been willing to pay whatever they must for a big-name school. For small regional colleges that struggle just to fill seats, merit aid can be an important revenue-builder because many recipients still pay enough tuition dollars over and above the scholarship amount to keep the institution running. But for rankings-conscious schools in between, merit aid has served primarily as a tool to recruit top students and to improve their academic profits. “They’re trying to buy students,”says Skidmore College economist Sandy Baum. Studies show merit aid also tends to benefit disproportionately students who could afford to enroll without it. “As we look to the future, we see a more pressing need to invest in need-based aid,”says Monica Inzer, dean of admission and financial aid at Hamilton, which has offered merit scholarships for 10 years. During that time, it rose in US News & World Repor t’s ranking of the best liberal arts colleges, from 25 to 17. Merit aid, which benefited about 75 students a year, or about 4% of its student body, at a cost of about $ 1 million a year, “served us well,”Inzer says, but “to be

大学英语四级常考语法总结
大学英语四级常考语法总结 一、虚拟语气。应着重复习能引起虚拟语气的某些介词、介词短语和连词(如lest, in case, otherwise等);一部分表示建议、主张、命令等概念的词语，由于本身隐含说话人的主观愿望，其后的主语从句、宾语从句、同位语从句往往采用“should+动词原形”;虚拟倒装句;在would rather, wish, as if, it’s time that等句型中使用适当形式表达主观愿望;混合虚拟句。 二、独立主格题。一般说来，在句子中没有连接词的情况下，逗号是无力连接两个句子的，其中一个分句要么是非谓语形式，要么是独立主格结构。两种结构都做状语，不同的是独立主格结构有自己的逻辑主语。 三、时态。英语中共有16个时态。四级考试中出现最多的是将来完成时、现在完成时、过去完成时和完成进行时。 四、名词性从句。形容词性的定语从句是考核的重点，用什么引导词，引导词前面的介词形式，引导词在从句中做什么成分，从句的语序等均有可能成为考点。此外，主语从句、同位语从句、宾语从句也应适当复习。 五、主谓一致。这类考题灵活性大，需要根据实际情况判断谓语动词的单复数形式。一部分具有生命意义的集合名词做主语时谓语动词多采用复数形式，如people, poultry, militia等;用and连接的成分表单一概念时谓语动词用单数;就近原则：主语中含有某些连词(如as well as, besides, in addition to等)时，谓语动词的数同第一个主语保持一致。
六、倒装结构。分为全部倒装和部分倒装。那些否定词(组)、介词短语能引起倒装句，部分倒装和全部倒装有和区别，as在倒装结构中的用法及意义等等，都是考生应当重视的地方。 七、非谓语动词。①根据非谓语动词同其所修饰的名词或逻辑主语的一致关系，确定使用主动语态或被动语态，然后考虑采用现在分词、现在分词被动式或过去分词;②非谓语动词同主句谓语动词动作发生的先后关系。动作正在进行的用现在分词进行式，同时发生或不分先后发生的用现在现在分词一般式或过去分词;在主句谓语动词之前发生的用现在分词完成式、不定式完成式;发生在主句谓语动词之后的多用不定式一般式;③表状态多用分词，表目的多用不定式。
