understanding 词义：名词：谅解，理解；理解力；协议。形容词：了解的；聪明的；有理解力的。动词：理解；明白。固定搭配：Understanding definitions 释义说明。用法：作宾语，被引用。They have to have a basic understanding
对……有更好的了解的英语短语是have an better understanding of。understand：一、读音：英 [ˌʌndə'stænd]，美 [ˌʌndər'stænd]二、意思：v. 懂得；明白；理解
For在这里是“就……而言”的意思,而第二个选项要抓住信息词still在此处的妙用,它是用来修饰比较级的,加上上文的cold,在此处就不难选择colder了。4、D 本题考查不定代词的本意区别及其与语境综合运用。此处none指的是not any vinega
clothes统指各种衣服,谓语动词永远是复数, cloth指布,为不可数名词 clothing 服装的总称,指一件衣服用a piece of, an article of 2. incident, accident incident指小事件, accident指不幸的事故He was killed in the accident.
当这种抽象词被形容词修饰的时候,可以用a.比如 a long history,a strong feeling等等
第一个空我不知道，但是第二个空应该填A ， A DEEP UNDERSTANDING 的意思是一个深刻的见解，所以填A；另外根据语感，你不觉得has the 很怪吗？
高三英语题:我第二个空有疑问。understanding 是理解里的意思,是不可数名词啊,可是为什么还用a修饰呢?
当knowledge指一个人对某一具体事物或具体学科的知识时，可以与不定冠词a连用（不管有无定语）如：He has an wide knowldge of history.当knowledge泛泛地指知识的时候，它是个不可数名词，不能与不定冠词a连用 如：Knowle
have a good knowledge of 精通；掌握；对…很熟悉 I have a thorough knowledge of the English language.我精通英语.I have a knowledge of astronomy.我懂一点天文学.He has a good knowledge of London.他对伦敦很
知识本身不可数 但是加了a good就是“对知识有一个很好的见解”的意思了,所以是可以用a的 不知解释清楚了没,如果还有问题问我
表示掌握了什么东西，是这样表达的，如 he has a good command of English他精通英语。a good knowledge of English,physics,French
a good knowledge???
must 还可以做名词和形容词 n 1.必须做的事;不可少的事物 A walking stick is a must for me now.如今我行走离不开手杖了。2. 一定要看(或听、读)的东西 a.1. 绝对必要的,必须的 此处的must 前面填a或不填
4. “may(might) + have + 过去分词”表示对过去发生的行为的推测。如: He may not have finished the work.[编辑本段]must和have to的用法 1. 表示必须、必要。(must表示主观多一些而have to则表示客观多一些)如: You mu
这是口语里很常见的用法，must在这里就是名词，表示必须做的事。意思就是做某事是很必要的。
knowledge在这里并不表示知识，而表示知道，了解，掌握 have a knowledge of就是最常用的一个词组表示掌握某事，这个a是这个词组里的固定搭配 在这个句子里，掌握英语这个短语被拿来用作名词充当主语，所以去掉上面的动词have
must可以表示名词和情态动词两种词性，在这个句字中是名词。所以要加a
有It is a must.这种说法，不用去a。must 可以做名词，也可以做动词。1、must做名词，为可数名词，复数形式为musts。意为一件必须做(或看、买等)的事。因此，在It is a must.中，名词must需要不定冠词a ，即a 不
must 在这里不是助词，是名词，意思是必须具备的，不可或缺的东西。在这种用法中它是可数名词。目前还没见到过用作复数。
It's a must to have a good knowledge of English nowadays.(must前面为什么要用a)
根据上述两条+选项是动词，空格处需要选为非谓语动词，因为英语的语法规定：简单句只能有一个谓语，即只能为一个“主系表”或“主谓宾”结构，如果需要使用其他动词，可以变成并列句、从句或非谓语。本句根据第2点，没有
1 朋友，就你的句子来说，没有一个选项是正确的。正确的表达必须是：As we know, __/__knowledge is a must in ___/__ international trade today.这里的knowledge是不可数名词，泛指各种各样的知识，所以不需要
选A 第一个 我想买 一些 东西。第二个 anything 可以表示任何事物，你什么都买得到，在那里。所以 答案是 A
第一空用an，有两个原因。1.application form是可数名词，必须有冠词，所以C排除。2.这个地方是泛指任何一张申请表application form，也就是你随便拿一张填写都行，所以肯定用不定冠词。现在我们剩下A、B两个可能选项。第
1.Be it ever so late, I must do another experiment.属于as, though 引导让步状语从句时Be谓语动词前置的倒装句。所以要选择A。2.as, though 引导让步状语从句时谓语动词的倒装。Try as he might, he didn't pass
sound在本句中用作系动词，意思是 听起来，后面一般跟形容词作表语。选项C和D均为副词，不符合。选项B用作形容词意思是 身体好的，不符合题意。故选项A正确。

It's bad for Chinese couples to have only one child.Because if there is only one child in the family, the child must be lonely.In the other country, each family have two or three children.The children in the family can play with others.That is good for their healthy. I think if there are two child in the family,the family must be happy and the children mustn't be lonely.一对夫妇只有一个孩子不好，因为孩子会感到孤单。在国外，一个家庭会有两到三个孩子。孩子们可以一块玩耍。我认为如果一个家庭有两个孩子，这个家庭一定幸福，孩子也不会因为没有人陪她玩而孤单。 The issue of whether to have a second child is one of the most difficult issues that parents nowadays face. There is a common argument agaist having just one child is that an only child may be more spoiled than one with siblings.Many people believe that a single child will not have learned to negotiate with others,and respect the give-and-take involved in many relationships.Some think this may leave the child less capable of interracting well with people his or her own age than one who has been raised with siblings. For some single-child parents,particularly those with busycareers,the pressures of devoting time and energy take care of their child,so it's necessary to have a second child to care each other. Many single-child parents feel a stigma associated with their decision to have only one child.There are no other children in the family for the child to associate with,and this mat lead to the children feel lonely at times,eapecially during vacations. Even more,we have no the right to break off the child's born right. Unfortunately,there is no simple answer to the question of whether or not to have a second child.The circumstances affecting each set of parents are unique,and what is appropriatefor one family may not be for another.The important thing,in the end,is to make a decision that both you and your spouse feel confident about.
According to the topic about if it's necessary to speak english in class, we had a debate. In my opinion, it's very necessary. There're 3 based on my views, check it as below: 1. English is the universal language now, and it has been widely used in the public places. And there're around 171 countries use english. There're english news, songs, movies etc. So based on this, why not speak as much english as possible in our class while we are in such an english environment? 2. Someone probably say their english is not good enough to grasp all what they teacher said in english, naturally they may not be able to get a good mark during the exams. well, I was wondering did you get a very good score, or did you grasp it well when all the knowledge was taught by your mother tongue? Like the old saying, Rome is not built in one day. If you are in such an environment at a very young age, then you will have no doublt to accept this education model, do you? 3. Most of people are interest in the western culture, and when you travel to a foreign country. Do you think you will have a very hard time, just for the reason that your english is not good to communicate with others? I think the answer is absolutely. The difference in language will cause alot of trouble and inconvience for us, and if we practice and speak alot in our classes, I bet there's no similar confussion any more. Like the old saying goes, Every coin has two sides. I can not 100 percent for us attending class all in english, it will also have some disadvantage for us. According to your(the opposite side) opinion, it shows repect to both our mother tongue and our culture when we use our own langauge instead of Englsih, to be honest, I am totaly agree with you over this, coz it will be a bit weird when you learn a native article, you have to translate it into English first Anyway, in nowadays, English is very important to us in a certain aspect. So, I think it would be a good practice for us to have class all in English. -------------- p.s.: 可能没有完全根据原文进行翻译哈，说实话，对于这段话，我个人的观点是，如果说只有英语课全部用英文来教学的话，这会是一个不错的尝试，但是如果其他学科也都用英文的话，首先不说我们能否理解一些专业术语，估计其他科目的任课老师也未必可以全部用英文吧，除非你们是全外教授课。 以上翻译仅供参考和交流学习！
