句尾可以有两个介词吗我想说：“我要和小明一起通过EMS寄一个文件”我可以说 I will send email to y

可以啊

had ＋been（过去分词）是过去完成式.
have dinner是固定用法,have的过去分词是had.
所以就是had had dinner.

时间一般放句首.如果都放句尾,先地点,后时间

句尾句首都有,情况不同,自己看例句吧!
at any rate
adv.
无论如何, 至少
例句
At any rate one mosquito less.
又一只蚊子灭绝了.
At any rate they might help.
不管怎样,它们可能会有好处.
At any rate, orders must be obeyed.
但是,命令是要执行的,指挥是要服从的.
She was provided for , at any rate.
她的生活总算有了着落.
At any rate the task must be fulfilled.
无论如何,任务总得完成.

also,as well,either
also不能用在句末,只能在句首或者句中
比如I also have a car./Also I have a car.
as well可以和too一样放在句首
比如I have a car as well.
either是用在否定句中表示"也..."
比如I don't have any money either.

要看句子的.给两个例句你.The place is good to live in.这句中live in后面指的是place,也就是说这句话还可以说成 It is the good to live in the place.没有live place这个说法的,要用live in.另外一个句子：It is hard for them to live.这句话中live后面接的是hard,live hard 生活困难,这里就不需要加in.什么时候加什么时候不加要看live后面接的是什么,稍微分析下句子就能知道了.

上面你提到的知识点是“反义疑问句”,核心词：前肯后否 、 前否后肯
He is never late,is he?---前面的never表否定,后面要用肯定语态
He is often late,isn't he?---反之前面肯定,后面用否语语态
Tom seldom watches TV,does he?---为什么这里会多了个does he?而不是Is he 或 isn't he?
要用到另外的知识点,be动词和助动词; 然后反义疑问句的动词应于主干句的动词保持一致.
,明白没?

我不是专业解答,不过我认为冒号和上引号留在句尾时应该是2,顿号在末尾应该是1,破折号在末尾这个得分情况,因为破折号占两个格,如果写完破折号前的最后一个字已经没有格了,那就另起一行,如果还剩一个格或两个格就写在末尾.
建议你还是找语文老师具体问问吧.

After 11:00 at night,somehow i can't fall asleep.
晚上11点后 不知为什么我睡不着
somehow 放在句尾句首都可以.比如：
1. 由于某种未知的原因;不知怎么的
Somehow he was afraid of her.
不知怎的,他怕她.
2. 以某种方式;用某种方法;从某种角度
I'll have it out with him somehow.
我总是要跟他决一雌雄的

a c

句尾

方式副词不一定放在句尾的.不同的方式副词有不同的位置,而且有些方式副词的位置也是不确定的,有多种位置的.We were deeply moved by the movie.我们被这部电影所深深地打动.My legs were so weak I could hardly sta...

一般很少用.
他一般是表示"经常",放在BE动词后,实意动词前.
但放在最后也不是不可以.
eg.They don't go to the park very often.

示例：音乐没有手指，却能拨动人们的心弦；音乐没有双翅，却能飞越时空的距离；音乐没有身躯，却凝结着人类情感的晶体。（答案不唯一）

每至晴初霜旦,林寒涧肃,常有高猿长啸,属引凄异,空谷传响,哀转久绝.
视 听
抓住景物特征来写是这篇课文的最主要的写作特点.从自然形成的角度来看,三峡是离不开山水的,因此突出其山水,是不言而喻的.但山水中有四季的变化穿插其间,这就不能写一时一处的景色,而是要在四季变化中展现三峡奇异诡谲的美景,寓静态于动态之中,动静结合,写出三峡的整体的富于动感的景色,这就是典型化的手法.没有典型化的手法,是写不出三峡的美景的.
抒发对祖国的热爱之情

一般是在句尾.
如：He is trying to go home as quick as possible.

一.instead意为“代替”“替代”,作副词用,通常位于句尾.如位于句首时常用逗号与后面阁开.instead 在顺接句子中作“代替”讲,而在转折（或逆转）句子中作“然而”讲.
例如：1.Lily isn't here.Ask Lucy instead.
Lily不在这儿,去问Lucy吧.[注意]当instead在祈使句中时,只能位于句末.
2.she didn't answer me,instead,she asked me another question.
她没有回答我,反而问了我另外一个问题.
二.instead of是介宾短语,其意与instead相同,不同之处在于它后面常接宾语,起宾语多由名词、代词、介词、短语、动词 + ing 形式充当.
例如：1.We'll ask Li Mei instead of Mary.
我们将去问李梅而不问玛丽.
2.I'll go instead of her.
我会替她去.
三.instead 与instead of的转换.
例如:1.He didn't answer me,instead,he asked me another
question → He asked me another question instead of answering me.
2.I'll of instead of her.→She won't go.I'll go instead

如果以这个助词结束句子,这么理
显得语气柔和、委婉,不把话说死,留有余地、意犹未尽.
请参考!

没见过放句中的,放句中整个句子怎么会通顺.一般在句首或句尾.

可以直接放在句首,不用加逗号

后面省略了一个宾语him

完成时态

as可用作连词,引导比较、时间、原因及方式等四种状语从句,应注意的是,引导的比较状语从句往往有省略；引导的时间状语从句一般用一般现在时而不用一般将来时；引导原因状语从句时与“Because”和“since”引导的从句比较起起来语气最弱.
as作介词,意思时“作为”,“以……身份”.例如：He came to China as a tourist five years ago.
而表示像…一样时,like通常作介词用,而介词后面通常接名词,代名词和动名词.
as in Australia“和在澳大利亚一样”.
as……as
AS +adj(原级)+AS
AS +adv(原级)+AS
as soon as 一……就
as soon as possible 尽可能快地
as early as possible 尽可能早的
as carefully as you can 尽可能认真地
as careful as you can 尽可能认真的
1.as是连词,表示“随着”的意义.lives是life的复数,意义是“生活”.

2.as是连词,表示“因为,由于”的意义.wanting是现在分词,表示主动意义,wanting to buy cars=who want to buy cars.
As的用法小结
as可以作连词、介词及关系代词和副词.现将其用法小结如下:
（一）、 as作连词的用法:
1.作“在-------期间,当----的时候”引导时间状语从句.注意与when、 while的用法区别.
①下列情形时,只用as,而不用when或while.
1)用于表示同一个人的两种动作交替进行,指一边----一边.如:
The girl sings as she goes to school.
He looked behind occasionally as he went forward in the forest.
2)表示两个同步发生的动作或行?意思是随着-----的发展.如:
As time went on / by,she became more and more beautiful .
As children get older,they become more and more interested in everything.
3)表示两个短暂行为或事情几乎同时发生.如:I watched her as she read the book.
I thought of it just as you opened your mouth.
Just as the flying worm hit her face,she gave a loud cry.
4)接在名词后面表示某一个年龄段时.如:
As a young man,he was active in sports.
②when作"当……的时候"解,可以指较短的(一点)时间,也可指一段时间.如:When I was at college,I could speak several foreign languages.When the clock struck twelve,I had slept for 2hours.
③ while常表示一段较长的时间或一个过程,强调主句谓语动词与从句谓语动词同时发生.如:Work while you work.Play while you play.
2.As =Since 作"既然"、"由于"解,引导原因状语从句,常用来表示已为人们所知或显而易见的原因或理由.如:As he’s been ill for ages,I will help him.
As / Since you're not feeling well,you may stay at home.
As he wasn't ready ,we went without him.
3.As =in the way that作"像"、"按照……的方式"解,引导方式状语从句.如:
Do as I told you.
Remember,you must do everything as I do.
4.用于as--- as或not / so/ as ---- as中,前一个as是副词,后一个as是连词,引导比较状语从句.如:They helped the old as much as possible.
I don't speak English so/ as well as she does.
5.表示虽然,尽管 等,引导让步状语从句,常用倒装语序,模式为:
adj./adv./ n.+as +主语+谓语+主句.如:Young as he is,he knows much.
Tired as they were,they walked on.
6.表示也------一样.She is a doctor,as was her husband.
（二）、 as作关系代词,引导定语从句,表示正如,这一点.如:
He is very careful,as we all know.
As is well-known,Taiwan belongs to China.
另外,当先行词被the same,such等词修饰时,常用as来引导定语从句.如:
Such a clever girl as she can learn anything quickly.
I was reading the same book as he bought yesterday.
（三）、as作介词的用法.
1.表示好像.如:He dressed as a policeman.
2.表示作为当作.如：I found a job as a guide.
3.当某人是某身份时.如：As a child ,she was sent to abroad.
4.as引导的介词短语大多用作状语,as译为"作为";少数情况可引起宾语补足语.如:
As a Party member,I'll take the lead in everything.(状语)
She works as a model.(状语)
She has me as one of her best friends.(引起宾语补足语)
（四）、作副词的用法 1 表示与------等同.如：This dress is twice as expensive as that one.2 像,如等.如：As before,he remained unmoved.
总之,通过以上的分析,我们对as的词性和用法有了比较全面的理解和把握,才能在实际的运用中做到心中有数,应付裕如.

双音节：嗟乎,呜呼.
单音节：哉,也,兮,乎,焉,耶.

as...as中间用原级,不能用比较级和最高级

mine是名词性物主代词,意为“我的”,可以作表语、主语、宾语.
LS所举的两例It's mine.His book is Chinese,mine is maths.分别对应前两种情况.
再在字典里翻些例句：
She's an old friend of mine.（介宾结构）
另外mine作名词可以解释为“矿井”“地雷”.

什么时态,都可以,看下面例句 1. The man was so genial, so I was drawn to him at once. 这人这么和蔼, 我立刻为他着迷. dict.cn 2. We agreed to leave at once. 我们同意立即离开. dict.cn 3. Since she is seriously ill, we have to send for a doctor at once. 既然她病得厉害, 我们要马上去请医生. dict.cn 4. We determined to go to the railway station at once. 我们决定立刻去火车站.

可以啊 比如 you are handsom or you are beautiful handsom 和 beautiful都是形容词 意思是 英俊的和漂亮的

可以
也可以放在句中
例子：I have too much pressure.我有太多的压力
He boasts too much.他的大话说得太多了

焉:一般前边有了动词,后边没有做宾语的名词或代词等.
如:积土成山,风雨兴焉.

不一定,要看前面有没有动词的宾语,没有,就不加,有,要加

magnificant
spectacular
最常用的了

放在句首,表示强调,给人一种先声夺人的艺术效果,增强了作品的吸引力.放在句末未必有这种效果.

either放在句尾,用于否定句

one day的意思是“过去/将来某一天,既可指过去也可指将来,表示不确定时间的“某一天”.例如: One day last
week,she rnet a friend of hers in the street.(过去)· 上星期的一天,她在街上见到了她的一位朋友. We
have lost 100 times,but one day we shall win.(将来) 我们输了100次,但总有一天我们将会赢.one day 在句子中的位置比较灵活,可放句首 句中 句尾,影响不大.

句尾
eg:
I hope you give the score to me right away.

对,重音在前面,末尾轻声造成音变.蒙古语满语都有这种现象
比如末尾的a音因为轻声因变成e,再轻读尾音脱落（如果末尾后面没有辅音）,如afan-afen；e音轻度脱落,比如muse（咱们）-mus~还有o-u-e这类的音变,一般都是因为末尾轻声,或者是说得很快的原因导致的.
以上均是以满语为例

都可以
如果强调这个频率"有时"可以放在句首 没有什么特别大的区别

用客气的语气表示祈使句时,可在句首或句尾加上please,但如果在句尾加please,那在please之前一定要加一个逗号“,”.===基本上是没有区别的

cost

in fact

etween them
There is no room between them.
它们之间没有空隙.

介词是一种用来表示词与词、词与句之间的关系的虚词,在句中不能单独作句子成分.介词后面一般有名词代词或相当于名词的其他词类,短语或从句作它的宾语.介词和它的宾语构成介词词组,在句中作状语,表语,补语或介词宾语.介词可以分为时间介词、地点介词、方式介词、原因介词和其他介词,
我们常常听人家说：不要把介词（prepositions）放在句尾,以免削弱句子的气势.
实际上,英语的介词是可以在句尾出现的；有时还是非在句尾不可.请看这句：
“I may give you financial aid.But it all depends on what the money is for .”
这句话的介词“for”在句尾出现.如果把“for”移到宾语之前,就不合句法了：
*“……But it all depends on for what the money is.”
这么看来,英语介词是可以放在句尾的.既然如此,在什么情况下,英语介词才可以放在句尾呢?
常见的情况有下面 4 种：
一当疑问代词或疑问副词作为介词的宾语时,理论上要在介词后面出现,但在实际用法上,它被转移到疑问句前头,介词则留在句尾.例如：
① What are you dreaming of?
② Where are you from?
①不能改为“Are you dreaming of what?”也不能是“Of what are you dreaming?”②不是“Are you from where?”,更不是“ From where are you?”
二介词不能移到限定性形容词分句中的关系代词（the relative pronoun in the restricted adjective clause）之前；因此,我们可以③表示心意,但不能用④这样的句子：
③ Is this the book that you asked me for?
*④ Is this the book for that you asked me?
同样的,⑤是对的,⑥是错的：
⑤ This is the goal that we are striving towards.
*⑥ This is the goal towards that we are striving.
三在不可分开的片语动词（the inseparable phrasal verb）里,如果介词在句尾,也只好随遇而安,不便移动.例如：
⑦ This is something which I refuse to put up with.
⑧ Such a matter should be immediately dealt with.
⑨ An 8% increase in salary is not to be sniffed at.
⑩ The rising cost is really a thing to be reckoned with.
四当带介词的不定式动词修饰名词而又出现在句尾时,这介词只好保留在原位.例如：
11.David is a nice person to work with.
12.I like to have someone to talk to.
13.This is not a comfortable place to live in.
14.Give me a good pen to write with.
15.Is this a box to put coins in?
16.There is some useful information for you to refer to.
综上所述,英语介词不但可以在句尾出现,有时还非在句尾不可!
除了所举的情况之外,尽量避免把介词放在句尾.例如17－19虽没有什么问题,但不如20－22好和自然：
17.Can you tell me whom do you share your office with?
18.This is the last way which the idea can be pushed through.
19.What reason have you chosen this scheme for?
20.Can you tell me with whom do you share your office?
21.This is the best way through which the idea can be pushed.
22.For what reason have you chosen this scheme?

though放句尾.区别：①although和though同义,在一般情况下,可以互换使用.只是though较普遍,常用于非正式的口语或书面语中,而although则较为正式.另外although语气比though重,常用以强调让步概念.e.g.Though/Although...

我认为可以

auch nicht eben um die Ecke liegen = 不是拐个弯就到得了的
上下文可以理解为：
明天我一定要打足精神,因为要出差去Magdeburg,这地方说远不远,说近倒也不近.

当刻意强调这个时间时,放在句首并加上逗号 不刻意强调这个时间时,放在句末即可

A
finish+doing

这两个词放在句首或句尾在用法上是一样的,只是族在句首,就是两个句子,放在句中,就是一个句子,也就是说是用if或unless将两个句子连接成一个句子.
例:If it were not for your help,I would not have succeeded.要不是你的帮忙,我是不会成功的.
= I would not have succeeded if it were not for your help.
unless = if.not用来引导否定的条件句,也就是说用来代替否定的if从句.
例:If Max doesn't come on time,we will leave without him.如果Max没准时来,我们就不等他先走.
=Unless Max comes on time,we will leave without him.
not+unless=only...if 表示"如果...的话"
例:Venus won't come unless Nancy does.Venus不会来,除非Nancy有来.
=Venus will not oonly come if Nancy does.
注意,这里的only只是用来强调if ,与 if only(要是...就好了) 意思不同喔~
