as many=a number that is equal to another number 表示同样的数字
As early as 不是比较,而是规定时间范围的固定用法
able/unable to be done的结构错误
Ability to do (for doing 和of doing错)
Act as-----表功能
Act like---跟人
Aid in doing
Affect优于have an effect on
Aim at doing/ with the aim of doing
Allow sb to do(不能用虚拟语气should)
Appear to be/appear as +n./appear +adj./appear that
As being一定错
As...so/ just as .....so
as be the case (with)…,是 as the case be 的倒装形式,其常见的错误用法包括:as it be;than be the case;as in/with the case of;
Based on不能放句首,改为because of
Being可能正确的情况
infected does not make you sick.
例2 the judges saw the horses being led to the stables.
but后面本应该加句子的,但是在助于相同的情况下可以省略主语。如:
This class is heard to be useful ,but then proved useless.
Between A and B(不用with)
Among(several items) --后不接with, and
because of与on account of:
because of意为"由于,因为",强调因果关系,在句中仅作状语。because of 既可表示好的原因,也可表示坏的。大多数情况都是用于造成不太好结果的原因。
on account of与because of同义,但语气较为正式。on account of 非常客观的表示原因,适用于任何情况,可作状语、表语,不作定语。
Because of 并不是一定错,关键是Because of结构后面要紧跟核心原因
其他条件都满足的情况下,一般表示原因用because,当后面的原因是推测的时候用for最合适,当后面的原因是大家看到就知道(顺其自然)时用as/since最合适。
当 because of, by doing, because, due to, by + 名词等在选项句首,第一选择是 because连词,其次是 by doing,因为动词比名词更能表达的意思更完整。
capability of X-ing/in X-ing是wordy/awkward的
conclude的固定搭配:
conclude by doing sth./ conclude with sth.:以……结束,借此后面接的是结束的方式
She concluded by saying she was prou
