Unit 3
Could you please clean your room
Tony, could you please help out with a few things 托尼,你能帮忙做几件事吗?
help out (with something) 是一个动词短语, 表
示在某人繁忙或是遇到困难时“给予帮助”。
本单元中这句话:
You watch TV all the time and never help out
around the house!
你老是看电视,从不帮忙干家务。
Language points
I think two hours of TV is enough for you!
我认为你看两个小时电视就足够了!
此处,two hours of TV虽为复数,但却表达一种整体的观念。英语语法规定,当时间、长度、距离或其他可数名词表示一个完整的整体概念作主语时,其后的谓语动词用其单数形式。
Two months is quite a long time.
两个月是挺长的一段时间。
Thirty students is not a big number for a class.
30人对一个班来说算不上是大数目。
…because Mom will be back from shopping any minute now. …
因为妈妈随时都会买完东西回来。
any minute now 是一种常见口语表达,相当于“随时;马上;在任何时候”的意思,minute 还可替换为“second, moment, time”等。
e.g. we are expecting them any moment now.
我们期待他们随时到来。
And she won’t be happy if she sees this mess.
如果她看到这么乱会生气的。
mess意为“脏乱状态;凌乱状态”,一般用单数。
Your hair is a mess. 你头发很乱。
与mess搭配的常用短语有:in a mess, make a mess, clean up the mess 以及What a mess!
What a mess! Let’s clean it up!
好乱啊!咱们把它整理一下。
Could you please do sth.?
请你(做)……好吗?
Could you please not do sth.
请你不要(做)……好吗?
有礼貌地提出请求句型:
For one week,she did not do any housework and neither did I.整整一个星期她都没做任何家务,我也没做。
neither did I是“neither+be动词/助动词/情态动词+主语”倒装结构,表示前者描述的否定情况也适用于后者。该结构中的neither也可用nor代替。
【易混辨析】neither与so
neither+be动词/助动词/情态动词+主语 表示前者描述的否定情况也适用于后者。
so+be动词/助动词/情态动词+主语 表示前者描述的肯定情况也适用于后者。
neither+主语+be动词/助动词/情态动词 陈述前面的否定情况。意为“确实如此”。
so+主语+be动词/助动词/情态动词 陈述前面的肯定情况。意为“确实如此”。
“What happened ” she asked in surprise.
他惊讶的问道:“发生什么事情了?”

He looked at me in great surprise and asked for a
long while, “Don’t you just leave for Australia this
morning ” 他极其惊讶地看着我,好久才问道:
“你不是今早才离开去澳大利亚了吗?”

【易混辨析】pass与past

children. 在家中给他们的孩子提供一个干净、舒适的环境是家长们的事情。

and …for their children.

看作一个固定句型,表示“做某事是
人的职责”

And anyway, I think doing chores is not so difficult. 反正我觉得干家务也不太难。
anyway 是个副词,置于句首时,其后常常用逗号与其他成分隔开。意为“反正,仍然,依然”

because it didn’t pay well anyway.
anyway还可以表示“不管怎样,无论如何”

in order to意为“为了;目的是”,表示目的,后接动词原形,其否定形式为in order not to。它可位于句首或句中。
【拓展延伸】如果后接目的状语从句,则可用in order that或so that。
【易混辨析】spend,take,pay与cost

【易混辨析】be ill与fall ill
be ill 生病(强调持续状态)
