英语中情态动词的形式和时态是什么 What is the form and tense of modal verbs in English? Unlike other verbs, modal verbs have only one form, the base form, and only one tense, the present simple. You will be seeing her on Friday at Jackie’s house.I may be late home tomorrow evening.I might go to visit Grandma on Saturday. They do not have a to infinitive. They have no -s inflection in the 3rd person singular. He will be seeing her on Friday.She may be late home. o Since modal verbs do not have past tense forms, you have to use other verbs to provide some of the modal meanings in the past, e.g. past necessity is expressed by had to instead of must. I must visit Auntie May today.I had to visit Auntie May yesterday. o The modals shall and will are usually contracted to ’ll in spoken English. All the negative forms can be contracted to form a single word such as can’t, won’t, wouldn’t. These contracted forms are common in both spoken and written English. o o I will/shall = I’ll We will/shall = we’ll You mustn’t say things like that, Jane.John can’t come to my party. There are other contracted forms such as he’ll, we’ll, shan’t, and they’ll, which are common in spoken English but rare in written English. 本文来源：https://www.wddqw.com/doc/2bcdcda4adf8941ea76e58fafab069dc51224779.html
