You have been learning French for 5 years, haven’t you? 3）构成修辞倒装： Nowhere can he obtain any information about his sister. Hardly had he arrived when she started complaining. 4）代替限定动词词组：A: Who can solve this crossword puzzle? B: Tom can. B: Yes, do. 语气和态度。 1. 后面一般+动词原形 2. 一般没有人称和数的变化即第三人称单数不加-s 3. 一般只有现在式和过去式两种形式，但可以表示现在时间，过去时间和将来时间。 4. 情态动词没有非谓语形式，即没有to do, doing, done等形式 现代英语语法还将be able to(能够), had better(最好), would rather(宁愿),used to(过去常常)等列为情态动词。
