【人教新目标九全英语 I used to be afraid of the dark.】
1 million 的三种用法
【教材原文】This old man had a million collars.这位老人有一百万美元(P26)
million 的用法与hundred. thousand 和 billion 的用法:
(1)与具体的数字连用,不加-s.
The book sold more than two million copies.这本书售出了二百多万册。
(2)不与具体数字连用,要加-s,并与of连用,表示"数以百万计的"
Dinosaurs disappeared millions of years ago.恐龙数百万年前就消失了。
(3)与 a few,several,many等数目不很具体的词连用时,带不带复数词尾s均可。若不带复数词尾s,其后的of可以省略;若带复数词尾s,则of不能省略。
【温馨提示】百、千、百万用法奇,基数词来修饰，直接单数莫迟疑;若是效目不确切,此时必须用复数,of在后别忘记，

A. Thousand B.thousand of C.thousands of D.two thousand of

About people took part in the sports meeting.
2 "把它纷某人"的正确说法
【教材原文】This old man had a million dollars,and he gave it to charity,这位老人有一百万美元,他把它报给了慈善机构。(P26)
give sth.to sb.=give sb.sth.,意为"把某物纷某人;给某人某物",其中sb.是间接宾语,sth.是直接宾语;如果直接宾语思代词it,them等时,通常只能用give sth.to sb.,而不能用give sb.sth.
I gave some money to him.
=I gave him some money.我给了他一些钱。
Please give it to your mother.请把它给你妈妈。
与give用法类似,能够接双宾语的动词还有show,lend,teach,send等,直接宾语如果是代词it,them等时,则通常用show/lend/teach/send sth,to sb..

3 "调查"research
【教材原文】I'd give it to medical research.我会把它献给医学研究。(P26)
(1)research在此作名词,意为"研究;调查",通常为不可数名词,常与动词(词组)do.make,carryout等连用,表示"做或进行研究的工作",其后跟介词on或onto,再接研究的内容。
He has done a good deal of research on this subject.他对这一课题进行了大量的研究。
(2)research还可用作不及物动词,表示"对进行研究",后接介词into或on。

4 If是"是否"还是"如果"
【教材原文】He doesn't know if he should bring a present，他不知道他是否应该带份礼物。(P27)
(1)本句中if意为"是否",引导的思一个宾语从句,可用 whether替换,
He asked if/whether I could speak English.他问我是否会说英语。
She asked me if/whether she could come in.她问我她是否能进来，
(2)f作连词,还可意为"如果,假如"。引导条件状语从句,而且在复合句中如果主句时态是一般将来时,if引导的条件状语从句用一般现在时表将来，
I'll come here if it doesn't rain tomorrow.如果明天不下雨我就来这儿。
If you work harder, you'll pass the exam.
(=Work harder,and you'll pass the exam.)如果再努力些,你就会通过考试。

5 "其他的"用法也有差异
【教材原文】What If everyone else brings a present 如果其他人都带了礼物怎么办 (P27)
else与other都有"其他的"之意,但两者的用法是有区别的,一起看看吧!
单词 用法 示例
else 作形容词,意为"别的;其他的",通常用于疑问代词what,who,which或不定代词之后 Who else wants to join the English club 谁还想参加英语俱乐部
作副词,意为"另外,其他",通常用于疑向副词when,where,why 之后 Is there anything else in the box 箱子里还有别的东西吗 Where else did you go last night 昨晚你还去哪了
other 作形容词,用于名词之前 There are more other ways to improve your English. 还有更多别的提高你的英语的办法。

(2)Are there any ways to solve this problem
(3)You can ask somebody to help you.
6 总爱担心后果的what if
【教材原文】What if I don't know anyone 如果我不认识任何人怎么办 (P27)
本单元出现了很多以what if开头的问句,你知道如何使用what if吗
What if... "如果...该怎么办 ",这是一个固定搭配,相当于What would happen if... 故what if引导句子的谓语动词应该用一般现在时。What if常用来询问将来如果发生什么事(通常是令人意外或惊恐的事)的时候，"我们/我"该怎么办。
What if he can't come 如果他不能来怎么办
What if the weather is really bad 要是天气真的不好怎么办

7 乐于助人的"help with"
【教材原文】The foods you eat could help with this problem.你吃的食物可能会帮助你解决这个问题。(P28)
help with sth.意为"帮助做某事"; help sb.with sth.相当于 help sb.(to)do sth.意为"帮助某人做某事"
He is helping with the housework.他正在帮忙做家务。
He often helps me with my English.他经常帮助我学习英语
He often helps the old walk across the road.他经常帮助老人过马路。
【精练】

You have to the washing up.
(2)我经常帮助她学习中文。
I often her her Chinese.
(3)在周末,他帮助他妈妈做家务吗
Does he his mother to housework on weekends
8 初涉"定语从句"
【教材原文】If I were you,I'd talk to someone who looks friendly.如果我是你,我会和看起来很友好的人交谈。(P28)
在这个句子中,有一个定语从句who looks friendly修饰不定代词 someone,翻译时应把它放在 someone 之前，即"看起来很友好的人"。修饰名词或代词的从句叫定语从句,被修饰的词叫先行词。在本句中,someone是先行词,关系代词who引导定语从句。引导定语从句的关系代词有who, whom, whose, that, which等。
(1)由who.whom,whose引导的定语从句在这类定语从句中,who充当主语或宾语,但多作主语:whom 充当宾语;whose充当定语。
This is the doctor who saved my life.这就是那个救了我的命的医生。
The man (whom) we wanted to visit is an artist.我们想要拜访的那个人是一位画家。
The boy whose father is a pilot comes from Beijing.爸爸是飞行员的那个男孩来自北京。
(2)由that,which引导的定语从句
that 既可指人,又可指物,指物时经常可与which互换,在从句中作主语或宾语,而which则指物,不指人。
This is the book that/which tells about computer.这是一本介绍计算机的书。
