注意：在口语中，dare的各种形式常与不带to的不定式连用。如：Do you dare tell her what I said?
你敢告诉她我说的话吗？I didn’t dare look at him.我不敢看他。
7. shall的用法：
shall表示征求对方意见（多用于第一、三人称），如：Shall we go out for a walk?我们出去散步好吗？
在英语中，我们可以用其他多种方式提出我们的建议或征求对方意见。
(1).用“Let's do...”来提出建议。如：Let's go for a walk after supper.
(2).用“What/How about...?”来提出建议；about后接名词或动词ing形式。如：What about/How about a drink? What about/How about taking Tom with us?
(3).用“Why not...?”来提出建议，表示“何不 ”not面后接动词原形。“Why not...?”实际上是“Why don't you/we...?”的简略形式。如：Why not meet at the school gate at eight? Why don't we stay here another day?
(4).用“Would you like...?”来提出建议，意思是“你想要 吗?”Would you like后可接名词或不定式。如：Would you like a cup of tea? Would you like to go and see her?
因此，如果我们说：“去游泳好吗?”英语中可有这样几种表达法：Shall we go for a swim? Let's go for a swim，shall we? What about/How about going swimming? Why not go for a swim? Would you like to go for a swim? What do you think of going for a swim?
8. should的用法：
（1）.should意为―应该‖，可表示劝告、建议、义务、责任等。如：We should protect the environment.我们应该保护环境。
（2）Should have done表示对过去动作的责备、批评。如：You should have finished your homework.
你应该已经完成作业了。（事实上你没有完成。）
9. will的用法：
will表示意愿、意志、打算，可用于多种人称。如：I will help you if I’m free this afternoon.今天下午如果我有空，我就会帮你。
注意：
1、will在there be句型中的形式及其句式变换。
由于“一般将来时”的结构可以用“will+动词原形”来表示，所以there be句型的一般将来时的形式就是there will be。（一定不能说there will have）例如：There are many students in our
school.→There will be many students in our school. There will be a sports meeting next week.一定不能说：There will have a sports meeting next week.
