教你简单的吧
首先,你应该要知道什么是noun,verb,adjective,adverb
noun名词 table, Ali, father.....
verb动词 很多种类的动词, 但是必须知道的是 is,am,are,have,has,had都是动词,还有普通一点的就是play,talk
adjective形容词, beautiful, pretty,nice
adverb 形容动词的形容词 slowly, gently
I drive carefully.
i = noun
drive= verb
carefully= adverb
is, are
was,were
has written, have driven - present perfect , 过去做过的事情 i have eaten breakfast. 我吃过早餐
had chosen, had said - past perfect 这个是过去的过去 He had stolen a ring before Ali opened the door.
present and past perfect 的动词不是past tense,是past participle
我的英文也不是很好,只是懂这些。。不明再提问吧~
