三个英语助动词造句

英语造句如何用BE动词和助动词？~

What you have said does not relate to what we are concerned with now. (注：原题的标点符号有误）

英语中，改否定句或疑问句时，应该注意用好be动词、情态动词、助动词。规律是：先找be、情、助，无则“都打的（do, does, did）”。

即：1、如果原句中有be动词、情态动词或者助动词，就以相应的be、情、助为准。例如：
(1)He is at home. （有be动词）
He isn't at home.
Is he at home?
(2)I can work it out.(有情态动词)
I can't work it out.
Can you work it out?
(3)He has been there three times.(有助动词)
He hasn't been there three times.
Has he been there three times?
2.如果原句只有行为动词，那就要借助于助动词do,did或者did。例如:
（1）My grandpa lives in a villige.(注意动词还原)
My grandpa doesn't live in a villige.
Does your grandpa live in a villige.
（2）They had a good time there.(注意动词还原)
They didn't have a good time there.
Did they have a good time there?
(3) We work six hours a day.
We don't work six hours a day.
Do you work six hours a day?
您的这个句子的主语是What you have said ，即一个主语从句，从句子中我们知道谓语部分要用一般现在时态，故谓语动词要用现单三形式。

不知这样解释可否？

英语中，be动词选用单数还是复数，要由主语来定，主语是单数，就用单数，反之用复数。
◆ 句中含有be动词时：
肯定句： 主语＋be ＋ 其他
否定句： 主语＋ be ＋ not ＋ 其他
一般疑问句： Be ＋主语＋其他 ＋？
特殊疑问句： 疑问词（what / who / when / where） ＋ be ＋主语 ＋ 其他 ＋？
I am a teacher. You are right.
She is 16 years old. My father is at home.
The students are playing games. My teacher was ill yesterday.
There is a picture on the wall.
There are two books on the table.
★ be动词用法歌：
我用am，你用are，is 连接他她它。 单数名词用is，复数名词全用are。
变疑问，往前提，句末问号莫丢弃； 变否定，更容易，be后not莫忘记；
疑问否定任你变，句首大写莫迟疑。
★ be动词作谓语，它后面一般跟名词、形容词或介词短语。

2、助动词的用法。
英语句子按正常语序是“什么人或事物” + “做什么”，即，我们常说的“主语 + 谓语 + 其他”。
① 主语为I 或复数名词、代词时：
肯定句： I / We / They / The students ＋ 动词原形 ＋ 其他 ＋ 。
We watch TV every night.
变否定： 主语＋ don’t ＋ 动词原形 ＋ 其他 ＋ 。
We don’t watch TV every night.
一般疑问句 Do + 主语 + 动词原形 + 其他 + ？
Do you watch TV every night?
Yes, we do. / No, we don’t.
特殊疑问句：疑问词 + do + 主语 + 动词原形 + 其他 + ？
How often do you watch TV?
② 主语为单数名词或代词时：
肯定句： 主语 + 动词第三人称单数形式 + 其他 + 。
He watches TV every night.
否定句： 主语+ doesn’t+动词原形+其他+。
He doesn’t watch TV every night.
一般疑问句：Does + 主语 + 动词原形 + 其他 + ？
Does he watch TV every night?
Yes, he does. / No, he doesn’t.
特殊疑问句：疑问词 + does + 主语 + 动词原形 + 其他 + ？

助动词本身无词义,它仅仅是用来帮助主要动词构成各种时态、语态、语气以及否定和疑问结构。
1)由be，have，shall(should)，will(would)构成除现在一般时和过去一般时外的全部时态。如：
I shall be here any minute. 我将随时到达这里。(由shall构成将来一般时)
The train is now rapidly approaching the city of Beijing. 火车现在正迅速临近北京城。(由is构成现在进行时)
We shall be having rain, rain, and nothing but rain. 我们会有没完没了的雨。(由shall be构成将来进行时)
The roads were full of people, which we hadn't forseen. 路上都是人，这是我们事先未料到的。(由had构成过去完成时)
Soon they would have reached their time limit and must return to the camp. 不久规定的时间就要到了，他们就得回营地了。(由would have构成过去将来完成时)
He has been scoring plenty of goals this season. 在这个(足球)赛季里，他踢进了许多球。(由has been构成现在完成进行时)
2)由be构成被动语态。如：
One is not guilty until he is proven. 在没有证明有罪之前，人都是无罪的。(现在一般时的被动式)
She almost felt that she was being mocked. 她几乎感觉到她在被嘲弄。(过去进行时的被动式)
I suspected that I had been followed and watched since I arrived in London. 我怀疑我到伦敦以后就已被跟踪和监视。(过去完成时的被动式)
I know he hates being interrupted. 我知道他不喜欢别人打断他的话。(动名词的被动式)
3)由had，should，would，should have，would have等构成各种虚拟语气。如：
If I had Jim’s build, I’d go out for the wrestling team. 假如我有吉姆那样的体格，我早就去参加摔跤队了。
The soup would’ve been better if it had had less salt. 假如少放点盐，这汤会好喝得多。
4)由do构成现在一般时和过去一般时的疑问结构。如：
When do we meet again? 我们什么时候再见?
Did you know the hot dog did not originate in the United States, but in Germany? 你知道“热狗”不是来源于美国，而是来源于德国吗?
5)由do+not构成现在一般时和过去一般时的否定结构。如：
Don’t knit your brow like that. 别那样皱眉头。
We didn’t think we’d be this late. 我们没想到我们会到得这么晚。
当两个或两个以上包含相同助动词的谓语动词并列时，后面的助动词通常省略。如：
The letter will be typed and sent off immediately. 这封信将立即打好并发出。
Having explained the rule and given a few examples, the teacher asked the students to write some exercises at home. 教师在解释完规则并举出几个例子后，要求学生回家做一些练习。
助动词在句中一般不重读，但当它在句尾代替前面的动词或强调动词的意义时则应重读。如：
—Do you speak English? 你会说英语吗?
—Yes, I do. 是，我会说。
But I have done it. 但是我把它干了。

如下：

1、To see a world in a grain of sand. And a heaven in a wild flower.

从一粒沙子看到一个世界，从一朵野花看到一个天堂。

2、Hold infinity in the palm of your hand. And eternity in an hour.

把握在你手心里的就是无限,永恒也就消融于一个时辰。

3、Life is a chain of moments of enjoyment, not only about survival.

生活是一串串的快乐时光，我们不仅仅是为了生存而生存。

4、To the world you may be one person, but to one person you may be the world.

对于世界而言，你是一个人;但是对于某个人，你是他的整个世界。

5、Never frown, even when you are sad, because you never know who is falling in love with your smile.

纵然伤心，也不要愁眉不展，因为你不知道是谁会爱上你的笑容。

助动词 do , He doesn't want to go to school today. 他今天不想去上学
助动词 be , I thought she was driving when the earthquake happened. 我以为地震发生的时候她正在开车
助动词 used to , I used to have a lot of money. 我曾经很有钱

do用于第三人称单数，did用于其他一些动词，does用于非第三人称单数。
