in the case of，就...來說, 關(guān)于,。意思跟上面兩個(gè)不一樣了,。一般表示轉(zhuǎn)而提及另一件事情。比如 In the case of woman,，they have more difficulty in their job,。就女性來說，她們在工作中會(huì)遇到更多的困難 

in this case:在這個(gè)場合

in that case:（短語）若是那樣的話 例：YOU don't like this place? In that case, why don't you leave?

=================================== 

In case of 和for fear of的用法區(qū)別 

1. 作“提防”,，“惟恐”這個(gè)意思講，in case of 和for fear of 是同義詞,，但不一定能通用：in case of 只能用來引導(dǎo)名詞,，for fear of 多半引導(dǎo)動(dòng)名詞短語。

 例如：In case of fire, break the bottle. 如果發(fā)生火災(zāi),，請把瓶打破,。 

      I always put some money in my pocket in case of need. 我總是要在口袋里放一點(diǎn)錢以備需用。 

2. 短語in case 是個(gè)連接語,，作“假如”,、“萬一”講。

 例如：And now Hercules began to consider what he should do, in case Atlas should be drowned in the sea.

      You’d better take an umbrella with you in case it rains.

 3. 同if不一樣,，用作連詞引導(dǎo)條件句時(shí),，in case這個(gè)短語通常用于陳述句，不用虛擬語氣,，而且意思也不一樣,。 

例如： 

In case I ask for leave, will she agree? 如果我請假，她會(huì)答應(yīng)嗎,？ 

If I were to ask for leave, would he agree? 如果我請假,，他會(huì)答應(yīng)嗎？ 

4. 即使主句是將來時(shí)態(tài),，由in case 引導(dǎo)的從句,，仍然使用現(xiàn)在時(shí)態(tài)。 

例如： 

In case the weather is fine tomorrow, we shall hold a meeting. 如果明天天氣好的話,，我們將召開一次會(huì)議,。 

Henry will resign in case you drive him too hard. 如果你欺人太甚的話，亨利就會(huì)辭職不干,。 

5. 作“以防”來講,，in case相當(dāng)于for fear that, 并可以通用。 

例如： I wrote it down in case/ for fear that I should forget it. 我已把它抄下了,，免得忘記,。 

       I must stay at home this morning in case/for fear that he comes to see me. 我今天上午必須呆在家里，恐怕他會(huì)來看我,。 

6. In case這個(gè)短語,，英美英語中的意思有時(shí)候并不相同,。 

例如：I will come in case I am wanted.  我會(huì)來的，因?yàn)橐苍S有人要找我,。（英式英語） 

     I will come in case I am wanted.  我會(huì)來的,，只要有人找我。（美式英語）

=============================

一,、case作名詞的用法: 

1. case有"情況,、事實(shí)"之意。如: 

Is it the case that you have lost all your money? 你的錢全都損失了, 是真的嗎?ed

The police have a clear case against the prisoner. 警察有充足的事實(shí)對付那個(gè)囚犯,。 

case作此義時(shí),常用于以下一些固定短語:

① in that / this case  如果那樣/這樣(的話);在那種/這種情況下

In that case, we'd better hold a discussion about the problem. 那樣的話,我們最好對這一問題展開討論,。

He may not be back at six. In this case we won't wait for him. 他可能六點(diǎn)鐘回不來。要是這樣,我們就不等他了,。 

② in case of  如果, 萬一,后接名詞,、代詞或動(dòng)名詞。如:

Take a spare tyre along in case of need. 帶只備用輪胎去,以備不時(shí)之需,。

Turn off the TV set in case of thunderstorm. 在雷雨時(shí),關(guān)上電視機(jī),。

In case of fire, dial 119 at once.  如果發(fā)生火災(zāi),立即撥打119。 

而in the case of則是"就……來說",。如:

Failure is no shame in the case of a scientist. 就科學(xué)家來說,失敗并非羞恥事,。

③ in case 萬一, 以防, 如果,引導(dǎo)條件狀語從句,。如::

In case he arrives before I get back, please ask him to wait. 萬一我回來前他先到了,請叫他等我。

Please remind me of it again tomorrow in case I forget. 請你明天再提醒我一下,免得我忘記,。

注意: in case引出的條件從句所表示的意義是"預(yù)防某種情況的出現(xiàn)";如果從句說的是一般的假設(shè)或條件,則要用if,。請比較:

I'll tell him about the matter if I meet him.  (不用in case)vw

Take an umbrella in case it rains.  (不用if )

在上下文意義很明確時(shí),有時(shí)可省去in case后從句的內(nèi)容。如:

I don't think it will rain, but I'll take an umbrella in case (it rains)

④ in any case 無論如何,相當(dāng)于whatever happens. 如:A`

You should finish your composition before school is over in any case. 無論如何,你必須在放學(xué)前完成作文,。"A]

In any case, I'll come over to the office tomorrow.  無論如何,我明天會(huì)來辦公室的,。`!

⑤ in no case決不,置于句首時(shí),須用倒裝語序。如:

In no case shall we allow smoking in the classroom. 教室里決對不允許吸煙,。y^'

In no case shall you break the rule.  你決不能違反紀(jì)律,。

⑥ such being the case 既然如此,情況既然是這樣Z

Such being the case, I have no more to say. 既然如此,我再無話可說。~;Ilw

Such being the case, we were very lucky to have a house of our own.  既然如此,我們能有一幢自己的房子就算很幸運(yùn)了.

2. case作名詞還有以下一些常見的意義:

There is a beautiful jewel case on the desk.  (盒子)

This is a case of fever.   (病例)Y4q^lG

There are five cases of flu among the staff.  (病人;患者)

When will the case come before the Court?  (案件)6unu

 二,、 case作動(dòng)詞,是及物動(dòng)詞,意為"將……裝入箱子",。如:

The goods have been cased up for transport.  貨物已裝箱待運(yùn)。

另外,be cased over with 則是"在……上另加一層物質(zhì)",。如:

The copper was cased over with silver.  銅上鍍著銀,。

The brick wall is cased over with cement.  磚墻上涂了一層水泥。

===========================================
