10． 活到200岁 live two hundred years old.

三．重点句型1have fun doing sth.
【句型介绍】 意为\"做某事有乐趣"，其中have fun 相当于enjoy oneself，表示过得愉快。【句式比较】 have a good / nice / wonderful time doing sth. / with sth.
Did you have a good / nice / wonderful time visiting that country?访问那国家你们快乐吗？
另表“做某事费力”have trouble/ difficulty/ problems/ a hard time doing sth./ with sth.
【特别提醒】 句中fun及trouble 为不可数名词，前不能用冠词。可用great、much、a lot of，lots of等修饰。
习题 1.it’s fun （swim）in the sea, we had great fun （go swimming）there.
2. what fun they had (visit) that amusement park.
3. Noneknows what great trouble we had (find)your house.
4． We had fun playing computer games. 我们玩电脑游戏很愉快。
2 英语中集体名词，如family, class,team等作主语时，若作为一个整体看，其后的谓语动词用单数；若强调其组成成员，谓语动词用复数。类似还有police和the+形容词表一类人时
My family is a happy one. My family are all watching TV.
3 在比较级中，要注意than后面人称代词的格。
1）当句中的谓语动词是不及物动词时，than后代词用主格还是宾格，意思上通常没有区别。如： He runs faster than I / me. 他跑得比我快。
They get to school earlier than we / us every day. 他们每天都比我们到校早。
2)句中谓语动词是及物动词时，than后面人称代词用主格还是宾格在意思上就有差别了。试比较： I like you more than he. (=I like you more than he likes you.) 我比他更喜欢你。
I like you more than him. (=I like you more than I like him.) 你和他相比，我更喜欢你。
在比较句型中，than后面的谓语动词常常省略。也可以用相应的助动词来代替与前面相同的谓语动词，以避免重复。如：
Tom does better at the lessons than I (do). 汤姆功课比我好。
She ate less than I (did) for breakfast. 她早饭吃得比我少。
4． 不定式作定语时，应放在被修饰词的后面，一般指一个还没有发生的动作。
如： Do you have anything to say about this? 有关这件事你有没有什么要说的？
5． You\'d better ... 是You had better ... 的缩写形式。 had better 为固定短语，意为\"......\"，后接动词原形，常用来提出建议或劝告，其否定形式是\"had better not + 动词原形\"。You\'d better not stay there too long. 你别在那里呆得太久。
6. Such作形容词，意思是“如此的”“这样的”，修饰各种名词。
Such这样的。如It is such bad weather.天气如此恶劣。
Such常和表示结果的that从句搭配，表示“如此….以至于…”如
It was such a hot day that we all had to stay at home.
Such…that…和so…that…都可用来引出一个结果状语从句。由于such是形容词，所以that从句前有一个受such修饰的名词；而so 是副词，用以修饰形容词或副词，因此that从句前一般不出现名词。如
They are such kind-hearted teachers that people in the village all respect them.
The exam was so difficult that many students failed to pass it.
a)如名词是可数名词的单数形式，such和so位置不同：
such+a/an+形容词+单数名词=so+形容词+a/an+单数名词即such a nice girl=so nice a girl
b) 如果名词是不可数名词或名词复数，只可用such,不能用so.:
such+形容词+不可数名词或复数名词，如：such good weather， such clever kids
c)如果被修饰的不可数名词被much, little, 或复数名词被many, few等表示量的形容词修饰时，用so，不用such.
语法要点一般将来时的用法：1）表示将要发生的动作或情况；2） 不以人的意志为转移，肯定要发生的事情。The day after tomorrow will be National Day.后天是国庆日。
3. in/after:in是指以现在时间为起点的“在一段时间以后”。也可以表示“在将来多少时间之内”，句子中的谓语动词要用一般将来时态，对此提问用how soon
after常指以过去时间为起点的“一段时间之后”，所以它与过去时态连用。当after指某个特定的未来时刻或日期之后，或指以将来某一时间为起点的若干时间之后时，它可以与将来时态连用。用”be going to +动词原形”也可表示将来时，表示将要发生的事，打算或决定要做的事。
4.more, less, fewer的用法区别：more为many, much的比较级，意为“更多”，可修饰可数与不可数名词。Less是little的比较级，意为“更好，较少”，修饰不可数名词。Fewer是few的比较级，意为“更少”，修饰可数名词复数。
【注意】few, little表示否定“几乎没有”==hardly any或not many/not much。
a few==several a little表示肯定“一点，几个”= a bit of ……。
5.would like sth意思为“想要某物“； would like to do意思为“想要做某事”。回答would like句型的一般疑问句时，其肯定回答为 “Yes, please.”;否定回答“No, thanks”或 “I’d like /love to, but….”
d) 当little表示“年纪小的”时，可用such+little+名词。
