三、知识点。
1. 情态动词。
情态动词有：can,must(必须),should(应当),would,may(可以),will(将要),shall.
2.使用方式：情态动词+行为动词原形(不受时态，人称的影响)
肯定句：he can speak english. they should go home now.
否定句： he can't speak english. they shouldn't go home now.
一般疑问句： can he speak english should they go home now
特殊疑问句：where can we go what should we do
注：be动词，助动词，情态动词为三种结构词。每个句子都会有其中一种，若要对句子进行否定与疑问的改动时，只要寻找这三类词。
3) 比较： 情态+动词原形 (i can swim)
like+ 动词ing (i like swimming)
would like/want + to + 动词原形 ( i would like to swim)
2. what does it mean？ it means ….
what do they mean ？they mean ….
3. different +名词复数= different things
the same thing(s) (same前面必须有the)
4. no+ doing = no smoking
not + do = you should not smoke.
5. a lot of与a lot用法的区别。
a lot of一般用来修饰名词；a lot一般用来修饰动词。
例如：a lot of things learn a lot
6. some, something用于肯定句；any,anything用于否定句和一般疑问句。
例：there is some water in the glass. i can see something.(肯定句)
there isn't any water in the glass.. i can't see anything.(否定句)
is there any water in the glass can you see anything (一般疑问句)
特例：would you like some orange juice
(表示邀请，征求别人意见，并希望得到肯定回答)
