care

1.care用作“忧愁”解用单数形式或复数形式都可以，用作“小心”解只可用单数形式。

2.take care of在英国只作“当心保护”解，它的宾语总是该被保护的东西，如Take care of your health和We must take care of public property。在美国往往用作“提防”或“对付”解。例如：You must take care of all possible obstacles和Can he take care of this problem?有时竟然有“杀掉”的意思。例如：They had many snakes to take care of in laying out the garden.

3.care of或in care of作“由…收下保管而转给他人”解，如I wrote to Mr Williams (in) care of Mr Cooke（我写信给Williams先生，是请Cooke先生转交的），在信封上习惯写作c/o或。例如：

Mr A. B. Williams

c/o Mr C. D. Cooke

注意c/o...是“由…转交”，不是“转交给…”，A c/o B是“由B转交给A”，不是由A转交给B。

4.I don't care作“我不放在心上”或“不以为意”解，但后面接了不定式便作“我不肯”或“我不愿意”解，如I don't care whether you will go or not是“我不管你去不去”，I don't care to go是“我不肯去”。但I don't care if I...却又作“我愿…”解，如I don't care if I go是“我愿去”。（这句直译作“即使我去，我也不以为意”，就是说“我不妨一去”。）

5.I don't care for（欢喜）novels比I don't care about novels普通。I don't care（肯）to go比I don't care about going语气重些。注意不可说I don't care for going。

6.可以说I don't care for you to see me。（我不要你见我。）

7.care to ...主要用在否定句、疑问句和表示条件的从句里。例如：

• I don't care to go. Do you care to go?
• If you care to go, I will go with you.

通常不说I care to go。但对于Do you care to go?可以回答说I care to go。也可以说That is all he cares to speak about。

8.I don't care what you say是“不论你说什么，我都不关心”，I don't care about（或for）what you say是“对于你所说的话我不关心”，但也可能跟前句意思相同。

9.Take care what you are doing是“留心你正在做什么（不可做你不该做的事）。”Take care in what you are doing是“对于你正在做的事，（你该）小心去做。”Take care of what you are doing可能有上面两句中任何一句的意思。

10.下面每组里的三句意思相同：

• We must take care that the fuel lasts out the winter.
  We must take care that the fuel shall last out the winter.
  We must take care that the fuel may last out the winter.
• We took care that the fuel lasted out the winter.
  We took care that the fuel should last out the winter.
  We took care that the fuel might last out the winter.

11.take care and ...=take care to ...（不定式），是美国用法。例如：Take care and get it done today.

12.可以说Owing to poor health he lived for some time in care of an old friend，但这里用in care of不及用under the care of普通。
