初中英语必备知识
1、宾语从句的语序问题
以上介绍了三种宾语从句,同学们一定要注意,在疑问词或if/whether引导的'宾语从句中,一定要用陈述句语序。
e.g.She asked how old I was.
We don’t know where her office is.
My teacher wanted to know if I like English.
2、宾语从句的时态问题
一般情况下宾语从句的时态必须和主句的时态保持一致:
当主句的谓语动词是一般现在时时,宾语从句中的谓语动词不受时态限制。
e.g.She says that she is a student.
She says that she was a student two years ago.
She says that she will be a college student soon.
She says that she has been a college student for 3 years.
当主句的谓语动词是过去时时,宾语从句中只能用过去的某种时态。
e.g.He told me that he would leave soon.
He said that he was watching TV.
He didn’t tell me whether he had finished this homework.
但如果宾语从句中讲述的客观事实、一般真理或自然现象时,则不受它限制。
e.g.My teacher told us that Yangtze River is the longest river in our country.
Father said (that) the sun always rises in the east.
1.get used to sth./ doing sth.习惯于……
2.as a matter of fact事实上
3.break out爆发
4.live a hard life过着艰难的生活
5.in need of需要
6.provide sb. with sth.= provide sth. for sb.提供某物给某人
7.one’s success in doing sth.成功完成某事
8.obey strict rules遵守严格的规则

10.aim to do sth.目的是
11.in the past sixteen years在过去的十六年里
12.at home and abroad在国内外
13.pay for付款
14.thousands of成千上万的
1. must
(1)must 表示主观看法,意为“必须”。
如:You must stay here until I come back.
Must I hand in my homework right now?
对must引导的疑问句,肯定回答为must,否定回答为needn’t 或don’t have to .
如:—Must I finish my homework?
—No, you needn’t.
(2)must也可以表示有把握的推测,意为“ 一定,肯定”,用于肯定句。
如: The light is on, so he must be at home now.
其否定形式mustn’t表示“禁止,不许”。
如:You mustn’t play with fire.
You mustn’t be late.
2. could
(1)can的过去式,意为“能、会”,表示过去的能力。
如:He could write poems when he was 10.
(2)could在疑问句中,表示委婉请求的语气,此时could没有过去式的意思。
如:Could you do me a favour?
—Could I use your pen?
—Yes, you can.(注意回答)
3. might
might为may的过去式。might表示推测时,表示可能性低于may(此时might没有过去式的意思),当请求讲时,比may的语气更委婉。
如:He is away from school. He might be sick.
Might I use your dictionary?
4. can
(1)表示能力,一般译为“能、会”,尤其指生来具备的能力。
