语义重复的词汇

一些词有时候离的远了，就看的印象不深了，所以总结起来，加固记忆吧，欢迎大家补充，然后我会修改帖子的

Ban 和cannot

Must和ensure

can和potential

regain和again

may和possible

explain和because, because of

there be…that

near和close

while和 simultaneously

after 和 subsequent

Now 和 currently

Require 和 have to

Additional和 another

per 和 single。。。但是要注意：

The yield per acre of coffee berries varies enormously in that a single tree, depending on both its size and on climate and altitude, could produce enough berries to make between one and twelve pounds of dried beans a year.

(A) enormously in that a single tree, depending on both its size and on climate and altitude, could produce

(B) enormously in that a single tree, dependent on its size and also on climate and altitude, is able to produce

(C) enormously, because a single tree, depending on its size and on climate and altitude, is able to produce

(D) enormously, because a single tree, being dependent on its size, climate, and altitude, is capable of producing

(E) enormously, because a single tree, dependent both on its size as well as on climate and altitude, could produce

第一二句，都是per acre …varies in a single tree.就是明显的重复，逻辑上也是不好的。

can和have the capability

possible和may
