ever用作副词,意为“曾经、以前、无论何时、总是”等。其用法比较灵活,现归纳如下:

一、用于一般疑问句,意为“曾经、这以前”现代汉语中一般不译出。

Does she ever go outat night?她通常晚上外出吗?

Have you ever beento Beijing?你曾去过北京吗?

When you wereworking there,did youever meet a foreigner?你在那里工作时曾见过外国人吗?

注意1.ever用于疑问句时,其答语中不用ever,若否定则用never,如:Have you ever heardthe song sung?Y es,Ihave.(No,Never.)

have 可以作为动词,译为:有,怀有,拿有,进行

作为助动词时,译为:已经

当动词用时,一般疑问句用do提问,例如:Do you have this book?你有这本书吗?

当助动词用时:

1)have +过去分词,构成完成时态,例如:

He has left for London. 他已去了伦敦。

Has he left for London?

2)have + been +现在分词,构成完成进行时,例如:

I have been studying English for ten years.

我一直在学英语,已达十年之久。

Have you been studying English for ten years?

3)have+been +过去分词,构成完成式被动语态,例如:

English has been taught in China for many years.

中国教英语已经多年。

Has English been taught in China for many years?

have been to 曾经去过(某地),(现在已不在那儿);可以与表示次数的词来连用。。

I have been to guangzhou many times.我去过广州好多次。

have been in +表示地点的名词,若要用here,there则省略in:

How long have you been here?你来这里多久了?

I have been here for three years.我来三年了。

Mary has been in China for two months.玛丽来中国两个月了。

注意:若要表达玛丽两个月前到北京的,则应用come的一般过去时:Mary came to China two months ago.
