中。 eg: There is nothing to do with you.

17. I can well remember that there was a time when a deep blue sky, the song of the birds, moonlight and flowers could

never have kept me spellbound.

(1) 这是一个较复杂的主从复合句。主句为I can well remember，后面是that引导的一个宾语从句，在宾语从句中又

含有一个定语从句。句中的a time为先行词，意为“一段时光”；when为关系副词，引导定语从句，修饰a time。 eg: It was a time when / in which there were few TV sets.

(2) 句中could never have done表示对过去发生的事情的否定判断推测，意为“(过去)不可能 ”。

eg: I could never have met him before. I know nothing about him.

can / could表示推测时，一般只能用于否定句和疑问句中，could比can可能性小。(could可以用于肯定句中)

18. …I stayed awake on purpose until half past eleven …

(1) until conj.&prep.其后可接名词或句子。

eg: I didn’t go to bed until midnight. (主句谓语动词为非延续性动词)

I worked on the farm until it got dark. (主句谓语动词为延续性动词)

当主句为否定句时，常把not until引导的部分提至句首，同时把主句部分中的助动词提到主语前，构成半倒装。 eg: Not until midnight did I go to bed.

(2) stay为连系动词，意为“保持” eg: How does sea water stay clean?

19. …I happened to be upstairs at dusk when the window was open.

happen to do意为“碰巧，恰好”。其后常跟不定式：to do(一般时)，to be doing(进行时)， to have done(完成时)。

eg: You happened to be out when I called on you yesterday. (不在家的一种状态)

My cousin happened to be sleeping when I went to visit him.

I happen to have been there, so I can act as your guide.

20….it was the first time in a year and a half that I’d seen the night face to face…

It / This / That is (was) the first / second / … time that…该句型常与完成时态连用：如果主句是一般现在时，从句用现

在完成时；如果主句是一般过去时，从句用过去完成时。

eg: It is the first that I have seen such a big fish.

That was the third time that he had been to the United States.
