四、作介词,

1. 表示 “好像(某人)”,例如:

They entered the building disguised as cleaners. 他们化装成清洁工人的模样进入大楼。

2. 表示“作为,当作”,例如:

I found a job as a teacher. 我找了一份教师的工作。

3. 表示“当某人是(某身份)时。例如:

4. 表示“因某人是(某身份)”,例如:

As her private secretary he has access to all her correspondence. 他是她的私人秘书,能接触到她所有的信件。

注意1:as引导的介词短语大多用作状语,as译为"作为",少数情况可引起宾语补足语。例如:

As a Party member, I'll take the lead in everything. (状语)

She works as a nurse. (状语)

Tom has me as one of his best friends. (引起宾语补足语)

注意2:as和like都可以作介词,但意义不同。as表示“以实际的身份或地位”。 like则表示“与…相似,以与…相类似的方式”。例如:

(1). He spoke as a teacher.

(2). He spoke like a teacher.

句(1)的意思是:“他作为老师发言”或“他以老师的身份发言”。句(2)的意思是:“他讲话很像是老师”。

五、用于一些固定搭配

2. as if /as though 似乎;好像

另外,as if可以接一个动词不定式短语。例如:

3. as well as 同(一样也);和;还
