Unit 16 What a good, kind girl!
Look! The children are still watching TV. 瞧!孩子们仍然在看电视。
3.情态动词与动词原形之间。如:
You could still ask him about it. 你仍能问他那件事。
4.作“还要、更”解时,用在形容词或副词的比较级前,表示程度,相当于even。
Jim's kite flies high, his brother's flies still higher. 吉姆的风筝飞得高,他哥哥的飞得更高。
辨析in time和on time
两个短语都有“按时、准时”的意思。
1)in time指“及时”,表示动作“在老人家时间内或提前发生”。如:
You'll get there just in time. 你将会正好及时到那儿(没误事)。
When he was hungry, I sent the bread to him in time.他饿时,我及时送了面包给他。
2)on time 强调“准时、按时”,即at the right time。如:
Please be come on time. Don't be late. 请准时来,别迟到。(不早不晚)。
The train came in on time.火车准时进站。
辨析So it is. / So is it.
1) So it is. “它确实是这样”。这种结构中的主语通常与上文的主语相同,主谓语不倒装,用于对上文的进一步肯定和确认。句型为:so+主语+be(have, 助动词或情态动词)。如:
—The students work hard. 学生们努力学习。
—So they do. 确实是这样。
2)So is it. “它也是”。这种结构中的主语与上文的主语不同,表示前句所说的情况也适用于另一个人(或物)。句型是:So + be(have,助动词或情态动词)+主语,意为“……同样/也那样。”如:
—English people eat a lot of potatoes. 英国人常吃土豆。
—So do we. 我们也是。
辨析maybe/ may be
1)maybe是副词,意为“也许,大概”。它通常放在句子的开头,在句子中作状语。如:
Maybe they won't come here tonight. 他们大概今晚不会来这儿。
Maybe she is happy. 也许她是幸福的。
2)may be是情态动词may加动词原形be构成的,在句中做谓语,意为“可能是、大概是”,后接形容词、介词短语或名词作表语。如:
She may be at home. 她可能在家。(也可以说:Maybe she is at home.)
You may be right. 你可能是对的。(也可以说:Maybe you are right.)
正误例析
你的钢笔可能在你的口袋里。
误:Your pen maybe in one of your pocket.
正:Your pen may be in one of your pockets.
Maybe your pen is in one of your pockets.
解析:maybe为副词“或许,可能”之意,在句中作状语;may be为情态动词may加系动词be构成,在句中作谓语,one of后面须接可数名词的复数形式。
关于not until用法分析
You mustn't eat anything until you see the doctor. 你在看大夫前,一定不能吃任何东西。
not…until…意为“直到……才……,在……以前不……”。在这个句型中,主句的谓语动词为非延续性动词,表示这个动作直到何时才发生。例如:
I won't leave until / before you come back. 你回来以前我不离开。(直到你回来我才离开。)
until用于肯定句中,主句的谓语动词为延续性动词,表示这个动作一直延续到何时为止。例如:
Go on until you reach the end. 你走下去一直走到头。
He waited until I came back. 他一直等到我回来。
