一、have表示“有”1用have直接表示“有”。如:I have a new watch我有一块新手表。2用have got 表示“有”,have got=have 。如:Have you got a ruler?你有一把尺子吗?当表示“有”时,have, has或 had的疑问式和否定式有两种构成方法。第一种方法是不用助动词。把have,has或 had提到主语前面构成疑问式,在 have, has或 had后加 not构成否定式。如:Has Wei Hua any storybooks?韦华有故事书吗?They haven’t any paper.他们没有纸。第二种方法是用助动词do,does或 did构成其疑问式和否定式。如:Do you have any bananas here?你这儿有香蕉吗?I don’t have a pencil-box我没有文具盒。英国人多用以上两种方法,美国人多用第二种方法。应当注意,用哪种形式提问,必须用同样的形式回答。如:-Have you a map?-Yes, I have(No, I haven’t)-Do you have a map?-Yes, I do(No, I don’t)注意:have表示“有”时,不能用于进行时态。不能说 I’m having an apple.,而应说I have an apple.。二、have用作助动词(无具体意义,只起语法作用),和过去分词连用,构成现在完成时或过去完成时。如:They haven’t seen the film yet他们还没有看过这部电影呢。Has he gone to the Great Wall?他已去长城了吗?三、have用作行为动词,可因后面所跟的名词的不同而有多种含义。如:We’re not going to have any classes next week下星期我们不上课。 When did you have a meeting?你们什么时候开的会?此外,还有have a rest 休息一会儿,have a swim 游泳,have a look 看一看,have an accident 出事(故),have a cough 咳嗽等。
First, “have” said “have” 1 “have” directly with “have.” Such as: I have a new watch I have a new watch. 2Use had got to say “have”,have got=have. Such as: Have you got a ruler? Do you have a ruler? There are two methods of constructing the question and negative expressions of have, has, or had when the expression “has”. The first method is to use no auxiliary verbs. Having had, has, or had mentioned the subject in front of it constitutes an interrogative, and adding not to a have, has, or had constitutes a negative. Such as: Has Wei Hua any storybooks? Wei Hua has a story book? They haven’t any paper. They have no paper. The second method uses the auxiliary verb do, does or did to form its interrogative and negative forms. Do you have any bananas here? Do you have bananas here? I don’t have a pencil-box. I don’t have a pencil case. The British use the above two methods, and Americans often use the second method. It should be noted that in which form questions are asked, they must be answered in the same way. Such as: -Have you a map?-Yes, I have(No, I haven’t)-Do you have a map?-Yes, I do(No, I don’t) Note: have means When there is “”, it cannot be used to perform tense. Can’t say I’m having an apple. I should say an apple. Second, has been used as an auxiliary verb (no specific meaning, only grammatical function), and used in conjunction with the past participle, constitutes now when completed or completed in the past. Such as: They haven’t seen the film yet They have not seen this movie yet. Has he gone to the Great Wall? Has he already been to the Great Wall? Third, has acted as a behavioral verb, but it can have multiple meanings because of different nouns. Such as: We’re not going to have any classes next weekWe don’t go to classes next week. When did you have a meeting? When did you meet? In addition, there was a rest for a while, have a swim for a swim, have a look to have a look, have an accident (have), have a cough cough and so on.
