assume
1.assume和presume略有不同。I assume that you can do it是“我假定你能做它”，assume后面通常有that，I presume you can do it是“我相信你能做它”，presume后通常没有that。
2.assuming不必属于固定的某词，如下面第二句也不算错：
- 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.
- Even assuming a great willingness on the part of all our friends to help, few of them are properly prepared for it.
