assume的用法

assume与presume都有“假定”的意思，但是前者只是一种假设，后者是认定是正确的，真实的，在等待被认定；

assume后常接that，而presume后不接that。

I assume that you can do it.

我假定你能做。

I presume you can do it.

我认定你能做。

使用assuming时，不用指明它是属于哪个固定的词。

Even assuming a great willingness on the part of all our friends to help, we must

not forget that few of them are properly prepared for it.

尽管我们假设只有部分朋友是情愿帮忙的，但我们不能忘了他们中的少数是真的准备了的。

Even assuming a great willingness on the part of all our friends to help, few of

them are properly prepared for it.

上面两个表达方式都是正确的。
