谢谢!!!

1.I can e-mail my family and friends back home for free.这里back是副词,修饰home,意思是回家,而back home本身也是个时间状语表示我回家后。
2.I told you to be home by 6 o’clock。这里也可以加at,但这里的home是动词,回家的意思;at home 是把home当名词。
3.They arrive back from vacation a day earlier than expected.她们提前到达,是跟之前的预测作比较,所以expect比arrive发生得早,所以是过去式。
4.Two hours won’t make a difference. 固定搭配。
5.base on和be based on 这里,base是及物动词,语法base sth on...它的被动语态就是be based on
6.The result is very important.It is supposed____a secret between you and me.A.to be kept B.to keep
答案是A,为什么不是B?因为这个秘密是被你和我守住,这里it作形式主语,主语不是人
7.---James didn’t turn up last night,did he?
---No.虚拟语气的问句只看最后,最后问did he?就是问有没有turn up? 回答no,就是没有turn up.
8.Children are B____by experts to take more exercise.A.suggested B.advised
9.What for?为什么 So what?怎么养?
10.The boy did a good deed and deserved_____.为什么to be praised值得被表扬,praising值得被表扬,praise应受到表扬
用法:【 1.deserve+n. 应受... 2.deserve doing 值得被做3.deserve to do 值得做...4.deserve ill/well of 有罪于/有功于】

11.They didn’t allow_____loudly there and people were also forbidden____there.
A.to speak;smoking B.speaking;to smoke答案是D,为什么不选C
嗯CD你都没给出来呢?我觉得答案应该是B。
allow 作“许可”,“允许”讲,只可搭配动名词短语作宾语,不可直接搭用动词不定式作宾补,即只可说 allow doing sth.
forbidden to do 固定搭配 禁止做某事

1。back是副词 用来修饰 my family and friends ,修饰宾语,指送XXX回XX
2。因为home是一个特例,前面不加at.比如 go back home
3。expected是期望,预想的意思,这里是比预料的早到
4。 make a difference。前面有定冠词a,所以不用加s
5。其实绝大部分都是用后者的,因为以。。为根据建立的,通常都是被动形式,比如 the novel is based on his story of life.
6。这里it 指代 前面的 the result,结果被守密,所以用被动。
7。回答者的全文应该是 No,he didn't.他没出现
8。A建议
9。前者可以看做 ”为什么“。
比如 -- lend me some money please. --what for? -借我点钱好吗。-为什么?(可以理解为,你拿这钱去干什么?) So what 是 【那又怎样】的意思。比如 --I am rich. --So what?
10。to be praised指被提升,to 与前面的deserve连用
praising用作名词,所以可行,praise应该也是可以当做名词形式的
deserve: 值得,应受到。。的奖励或惩罚。比如
you deserve to be awarded你值得被奖励。 you deserve it指 你活该
11。D 和C 呢?

打得这么辛苦,采纳吧。

1 back 是是副词,修饰home,意思是回家,而back home本身也是个时间状语表示我回家后
2at home是在家的意思这句话意思是“我告诉你6 点前回家”at home意思不通
3这是省略句,省略they are
4difference.既是可数也是不可数make a difference是固定短语“产生不同”
5翻译相同,后者较正式用于句子中
6主语是It即secret不是人,秘密是被保护的
7是的,他没出现,反义疑问句的用法
8选 B suggest只有主动式advise有主、被动
9What for为什么相当于why?what for是有怎样
10deserve doing/to be done /名词praise
11allow doing were orbidden是被动 要加to
希望我的回答对你有帮助,再祝你学业有成,加油哦!

1.back home是一起的,就是" 家乡的" 的意思
2.两者都可,be home,home 是adv ,at home, home 是名词
3.expected是预计的意思,比预计回来的早
4.是可数名词亚,他用了a了。
5.一个是主动一个是被动,被动用的较多。
6. 秘密是被保密的,SO是A,被动式
7。no,he did not turn up.没有出现。只要记住no 后面不可能是no,he turned up就可以了。yes 后面也不可能是yes, he didn't turn up.
8.b suggested语气太轻,建议 experts应该是 advised,告诫
9。what for 这是为何? so what这又怎么样!
10.to be praised=praising 就像need to be done=need doing是一样的道理。praise 则是名词了
11.forbid doing sth.

太吃力了。最好分开来问,这是我的建议。

1.back作为副词,在这里作为状语
2答案有误,副词不能作为表语
3这里用了省略句,原文是than it is expected
4.这里是固定搭配,make a difference意为有区别
5.前面base作为名词,后面是作为表语或者状语,比如
Our school has a large date base on the internet,
based on these proofs,we can draw a conclusion that
my evaluation on this plan is based on the last meeting
6.it是形式主语,代替secret ,和keep构成动宾关系
7詹姆斯作为没有出席,不是吗————不,他出席了
8A
9,意思是那又怎么样?
10deserve doing,或者deserve to do
11固定搭配,allow to do
