Yesterday a school boy WAS daydreaming in class.Not knowing WHAT he was doing ,he put a pen cap into his mouth .A few minutes LATER ,he was terrified to find that he had swallowed it !The teacher was SHOCKED when the boy stood up and said,"I've just swallowed a pen cap."He was quickly sent TO the nearest hospital .There a doctor examined him and said the best treatment WOULD BE to take some MEDICINE so that the pen cap could pass NATURALLY .Three hours later the boy successfully made it ."She is really lucky ." said the doctor ."It 's not rare that small children put things into their mouths for FUN .It's very DANGEROUS.

Helen's 是“Helen(海伦)”的所有格,意思是“海伦的”,也就是说“ 's”表示“的”的意思.
而 her(她的),当然不必加“ 's”

选C our已经是 我们的 的意思了.
ours后面不需要跟名词了.
记住如果后面有名词就要用C 意思是Miss Li是我们的音乐老师.
这句话选D是行不通的.如果你要用D就成了 Miss Li是我们的.

正确答案应是C
首先根据上下文可知,当他朋友问他怎么了时他还在想这件事,说明该动作从过去持续发展到现在,是延续性的动作,所以只能是过去进行式.在这里需要搞清楚,过去式只表示过去所做过的事情,而过去完成式表示过去所做的事情对现在的影响.他们都没有延续的意思.

I’m going to shop.
I’m going shopping.
这两种都是正确的表达方式.
be going to + 动原,和be + doing sth 都可以表示将要做某事.

美国确实是信用卡的海洋.美国人几乎买任何东西都用它,因为用卡有不小的好处.首先,使用现金越少,被偷的就越少.人们只需用卡支付,而不用从账户里取出现金.其次,人们还能打电话订购商品或服务,并通过提供卡的号码来进行支付.那可比签支票简单迅捷多了.然而,信用卡的使用也困扰了不少美国人.如果持卡人在当月底没有还透支的钱,他就已经欠债了.知道他还清为止,都要付很高的利息,通常都是20%.由于用卡买都是一个月之后才需要支付,很多人都无节制地花钱.当最终帐单送到手里,他们会发现自己根本没有那么多钱.[最后一句不完整]

选A
这是电话用语选A 是固定句式

主动词是increased,stationed为过去分词短语作后置定语（属于非谓语动词的用法）,限定missiles（不是任意的missiles,而是部署在西欧的missiles）,可变为定语从句：missiles that were stationed in Western Europe.

A
这是部分否定
不习惯用B,除非说Nobody/ No one
Only some people
Just some people

就谈一下对这句话的体会吧：
Does real beauty mean looking like everyone else?
i dont think so.
why would you want to look like everyoen else? We all have our imperfections. It's what makes us human!
sometimes we might be so self conscious because we look so different. just remeber nobody is perfect and we r all beautiful.
Never be bullied into silence. Never allow ourself to made a victim. Accept no one's definition of our life; define ourself.

人的生命是短暂的,然而如果是过的是卑鄙不如意的生活,则太久了.----威廉姆斯莎士比亚

主语：the sad mother
谓语动词：sat
处所状语：on the roadside,（指 sat 的地方是“在路边”）
伴随状语：shouting as she was crying （表示 sat 的同时伴随着“一边哭一边喊叫”）


注：


分词短语可以作时间、原因、条件和伴随方式状语.
连词 as 表示“在…的过程中”
这个句子也可以改写为The sad mother sat on the roadside and,at the same time,shouted as she was crying.

PS：弱弱的附一句,这些句子貌似是我们以前翻译课的练习啊...

1.a(2b-1)
2.5/3
3.(3x-5)(5-2x)=-6x^2+25x-25 所以a=-6,b=25,c=-25

1、few的意思是几乎没有,表示数量极少,修饰名词的时候相当于否定,谓动用单三.如果改成a few years,后面的谓语就要用have了；
2、the＋形容词,表示具有这一类特征的人或事物,比如：the young年轻人.

1.第一个回答就是了
2.标况下,气体都是22.4L/mol,二氧化碳就是0.5mol,原子数1.5mol,氢气是2g/mol,所以是1.5倍
3.分别看摩尔质量,看看每个原子所含质子数,算一下吧.会了吧.这种只能硬算,没有捷径.
4.(AL)=Bmol,溶质是（AL)2(SO4)3,所以是B/(2A)
5.假设分别是1升,那一共有0.3mol氯了,2L溶液,所以是0.15mol/L

我想说点什么,但是该如何开口?我总是在等待某个人,但是这太难了.你知道这有多困难.现在我决定保持沉默.因为如果我有所牵挂,我就不能前行.我会停留下来.然后我认识到,在梦想和现实中间,没有平衡.

第一句的宾语从句里有would,说明是过去时态.从句意看,期望是在他没有修好之前,而没有修理也是在过去,过去的过去,过去完成.
第2句中,句意是他本来想好这个星期修,但是这个星期太忙了.后面并列句中I've been too busy说明是预期在先,自己很忙在后.所以用过去完成.

从语法上看,第一句是正确的.意思是：两个学校中的任何一个都有其他学校所没有的东西.
第二句语法有问题：既然是否定词Neither开头,且作为副词使用,就应该用倒装形式,且school前加上the句子更通顺流畅,正确的写法有两种并且意思也不同.
第一种是倒装形式,：Neither has the school anything the other hasn't got.这句话的意思是：“这个学校也同样没有其他学校所没有的东西”,由于此句neither是否定副词故而倒装.
第二种是不倒装的,：Neither of the school has anything the other hasn't got.这句话的意思是：两个学校都没有其他学校所没有的东西,由于此句neither所连接的是of the school的名词词组,将neither of the schol作为整体一个名词来看待,故而不倒装.
但是要注意!这两句的意思是不同的,前者对象只有一个学校,后者对象是两个学校.
记住,一旦句子的开头是否定词,且作为否定副词,一定不能忘了倒装,这是考试中常考的也是比较容易错误的一类.

轴对称和中心对称不一样.中心对称是指一种对称关系.
对称中心是指在这种关系中,函数是以这个中心对称的.

It是主语是第三人称单数所以用takes
这是常用语法不用天才就知道了

ising living与inflation并列 ,此时rising为adj,表示日益增加的,而不是单独与check并列

as 引导从句的时候,本身就起到主语的作用.

1 What are , going ,do with your
2 Why not go
3 too, to
4 I am going to do what I want to do.
5 Don't open

正确答案确实是C.
在这个句子中,"having been addressed" 是作状语,补充说明主语"My letter"; 而在状语中,没有主语的情况下,助动词必须得变成动名词,所以这里必须用having.
全句的意思是:我的信写错了号码,所以很晚才被送达(到他手中).
