新年快乐哦,我来回答:
(1)一般现在时:A.句型结构:主语+be(am/is/are)+名词 eg:He is my broyher.
B.或是:主语+动词原形+其他成分 eg:I I go there by bus.
用法:当表示一经常发生的习惯性动作,没有明显的时间界限时,用一般现在时.
(2)现在进行时:A.句型结构:主语+be(am/is/are)+动词的ing形式(现在分词) eg:He is doing his homework now.
用法:表示当下正在进行的行为,常常有明显的时间词作标志,如now,at this moment等.
(3)现在完成时:A.句型结构:主语+助动词(have/has)+过去分词 eg:I have finished my homework.
用法:表示已经完成的事情,并且结果对现在造成了影响,为了加强语气,常可加already(已经),yet(还没),ever(曾经),never(从未)等.(特别强调:never已经表示否定,不能与否定同时使用 eg:I have not been there before./I have never been there before.)
(3)现在完成进行时:A.句型:主语+have/has+been+doing eg:I have been working busily all morning.(我从早上一直忙到现在)
用法:表示从之前到现在一直在做某事,也许到现在还未完成.强调动作的延续性.
(4)过去进行时:A.句型:主语+be(was/were)+doing eg:I was playing basketball yesterday when you called me out.
用法:表示过去正在发生的事.
(5)过去完成时:A.句型:主语+had+done eg:I arrived there but he had gone already.(他到达是过去,但他走比他到达还早,是过去的过去)
用法:表示事情发生在过去的过去.
(5)过去将来时:A.句型:主语+would/should+do eg:I would go there by bus.
用法:表示站在过去计划未来的事,如,你在昨天计划今天要做的事.
(6)there be句型:表示客观存在的人或物.eg:There is a tree in front of our house.(谓语动词采用就近原则)
(7)含情态动词的句子:情态动词:can/may/must/could/might...
情态动词无人称和数的变化.用过去时更表委婉.
eg:Can I borrow your pen?/Cpuld I borrow your pen?
若用后种问法,别人会更乐意借给你!
