初中时期必学英语时态所有结构?
一、一般现在时
(1)有 be 动词时:(be 有 am,is,are 三种形态,在此仅以 is 为例举例)
陈述句:Michael is a student.
否定句:Michael isn't a student.
疑问句:Is Michael a student?
回答:Yes, he is. / No, he isn't.
(2)有情态动词时:(以 can 为例)
陈述句:Jane can speak Chinese well.
否定句:Jane can't speak Chinese well.
疑问句:Can Jane speak Chinese well?
回答:Yes, she can. / No, she can't.
(3)当谓语动词为“实意动词”时:(以 go 为例)
陈述句:Tom goes to school by bike. / They go to school by bike.
否定句:Tom doesn't go to school by bike. / They don't go to school by bike.
疑问句:Does Tom go to school by bike? / Do they go to school by bike?
回答:Yes, he does. / No, he doesn't. / Yes, they do. / No, they don't.

二、现在进行时
结构:主语 + be + v-ing
标志:居首一般有 Look! / Listen! 句尾一般有 now / at the moment.
举例:
陈述句:He is doing his homework now.
否定句:He isn't doing his homework now.
疑问句:Is he doing his homework now?
回答:Yes, he is. / No, he isn't.

三、一般将来时
结构:
主语 + be going to do sth.
主语 + will / shall do sth.
举例:
陈述句:We are going to have a math test next week. / She will go to Beijing tomorrow.
否定句:We aren't going to have a math test next week. / She won't go to Beijing tomorrow.
疑问句:Are you going to have a math test next week? / Will she go to Beijing tomorrow?
回答:Yes, we are. / No, we aren't. / Yes, she will. / No, she won't.
(特例)
在“主语 + be going to do sth.”结构中,当动词为 come,go,leave,start,move 时,则用现在进行时的结构表达一般将来时的含义.在此以 go 为例:
陈述句:I'm going to Canada in five days.
否定句:I'm not going to Canada in five days.
疑问句:Are you going to Canada in five days?
回答:Yes, I am. / No, I'm not.

四、现在完成时
结构:
主语 + have / has + 过去分词
标志:already / yet 等
以动词 finish 为例:
肯定句:Maria has finished her homework already.
否定句:Maria hasn't finished her homework yet.
疑问句:Has Maria finished her homework yet?
回答:Yes, she has. / No, she hasn't.
(注意)
在现在完成时中,当动词为“非延续性动词”时(例如 open / close / leave / borrow / die 等),不能与表示一段时间的状语连用,但可以采用其他方式表达相同的含义.现以 die 为例:
翻译:他已经去世二十年了.
(错误表述)He has died for twenty years.
(正确表述)He has been dead for twenty years.
(正确表述)He died twenty years ago.
(正确表述)It has been twenty years since he died.
