at this time 在这时
Liz came to see me at ten/ teatime.
莉兹10点/在茶点时来看我了。
(4)during后必须跟一个名词,可以指整个一段时间。它有时可以用in替代:
It was very hot during the summer.
那年夏天很热。
He has phoned four times during the last half hour.
在这半小时内他打了4次电话。
但在下面的例句中则不可用in替代during:
I met him sometime during the week.
我是在这一周的某天遇见他的。
During the whole winter it never snowed.
整个冬季一直没下雪。
(5)from…till…指一段明确的时间:
The tourist season runs from June till October.
旅游季节从6月一直到10月。
(6)当所用动词只表示一个短暂的动作(如finish, leave)时,则只能在否定句中用till/ until:
I won't leave till/ until Monday.
我要到星期一才离开。
2.否定句的两种形式:not any与 no
对于一般疑问句,可以有两种否定的回答:
--Did you buy books?
--你买书了吗?
--No, I didn't buy any books./No, I bought no books.
--没,我没买书。
否定词no比not any的语气要强,但这两种否定的意义是相同的。no可构成复合词nobody, none, nothing, nowhere; any可构成复合词anybody, anything和anywhere。
在一个句子中通常只能有一个否定词(包括never, hardly等词):
It seems that nobody understands me.
好像没有一个人理解我。
I hardly go to school these days.
这些日子我几乎不去上学。
而除黑人英语外一般不说"I can't get no eggs."
