三、语法学习
1、had better 的形式和用法
1）固定短语had better具有情态意义，也可以看作情态动词。译为“最好”，它只有一种形式，没有人称和数的变化，后常跟动词原形，是给人提出建议的一种方式。如：
You had better go to see the doctor你最好去看医生。
You`d better eat a lot of fruit and drink plenty of water.你最好多吃水果，多喝水。
2）Had better的否定结构为 _________________。如：
______________________________你最好别吃辛辣的食物。
You`d better ____________ work today.你今天最好别工作。
2、shall的用法
1）作助动词时，英式英语中表示将来，可与第一人称连用，但在口语中所有人称都用will。如： this time next week Ishall/will be in New York.下周这个时候我就在纽约了。
拄：美语则不管什么人称，一律用will。
2）作情态动词时表征询意见，用于第一人称的疑问句中。如：
Shall Itake you to the hospital?要不要我带你去医院？
What shall we do this weekend?这个周末我们要作什么呢？
