Grammar Focus
1.连词 and
(1) and 连接两个并列成分
① “和”，否定句中用or。但如果前后名词都用no修饰，则可以用and。
The air was so warm and bright. It has no feet or legs.
It has no eyes and no ears. I have no sister or brother.
② “然后”。用于连接两句有时间上先后的句子。
She washed the dishes and dried them.
③ 表示目的，意图。用于go, come, stop, run, stay等动词后。
Come and have a drink. Go and buy one.
④ “只要……就会……”“如果……那么……”，
用于祈使句后，表示条件与结果的关系， “祈使句， + and + 句子”。 Knock on the door, and it will be e late again, and you’ll be fired.
2.连词 but
① 表转折“但是，可是，而，却”。
He is in poor health, but he still kept working.
② 用在表示歉意的话后，引起一个分句，这个but通常不译成汉语。 Excuse me, but can you tell me how to get to the railway station
③ 不与although/though (“虽然，尽管”) 连用。
Though he is old, he works hard.
He is old, but he works hard.
④ 作介词，表示“除了 之外”。
She did nothing but watch TV.
3.连词 because
because是连词，意为“因为”，可以用来引导原因状语从句。汉语中的“因为……所以……”常常连用，但在英语中because和so不能同时连用。如：
因为数学有趣所以我喜欢它。
Because Math is interesting, I like it.
= Math is interesting, so I like it.
The book is very interesting, so we all like it.
这本书很有趣，我们都很喜欢它。
= Because the book is very interesting, we all like it.
