例句解析
1. I think I’ll take the bus to the party.
If you do,you’ll be late.
我想我将乘公汽去聚会。如果你那样做，你将迟到。
在英语中，为了避免重复，常用do/does/did代替上文中的实意动词，这是助动词do的一个用法。
2. If they have it today, half the class won’t come.
如果他们今天举行，将有一半的学生不会来。
half the class= half of the class
(1) half作名词，意思是“一半，半个”复数形式是halves。常用于“half a/an+名词”结构；表示一个半时，可以用one…and a half或one and a half…+名词复数结构。Eg:It’ll take you half an hour to walk there.
(2) half作代词常与the,one’s连用，构成half the/one’s +名词
= half of the/one’s +名词。作主语时，谓语动词的数要有half后接的名词决定。Eg: half the students like math.
Eg: half the book was written by him.
3. If we ask people to bring food,they’ll just bring potato chips and choclate.如果我们要人们带食物，他们将仅仅带炸薯条和巧克力。
（1）ask sb to do sth要求某人做某事。Eg:The teacher ask us to study hard.
(2)bring带来，常构成短语“bring…to…”“把……带来……”，“take…to”“把……带走”。
