动词的过去式都是用在一般过去时态里面planted,而动词的过去分词是用在过去完成时和现在完成时里面。动词的过去分词还用在被动时态里面。

The trees were planted on the hill . ( were planted )

have /has+过去分词:现在完成时

Have you finished your homework?(have finished )

had+过去分词:过去完成时

He said that he had been there twice. (had been )

名词+过去分词:过去分词做后置定语

The girl named Mary is my classmate. ( The girl named )

过去式是过去的时态,过去分词是表示被动 ,也可表示完成时,

例如do-did-done

I did the job。过去时;

I have done the job,完成时:

the job is done,被动

grow和plant都可表示“种植”,但其含义和用法不同.

1.plant着重指“种植”这一行为.How many trees have you planted this year?你们今年植了多少棵树?Have you planted any trees yet?你种树了吗?

2.grow着重指种植以后的栽培、管理过程.The farmer grows wheat in this field.那位农民在这块田里种植的是小麦.He grew some flowers in the garden.他在花园里种了花.{注意}:某人plant之后树是死是活不一定管,但某人grow a tree则包括培育管理,使其生长的过程.

西瓜英文是watermelon 例句: I like to eat peach and watermelon, I like to eat mango and pineapple too. 我喜欢吃桃子和西瓜,我也喜欢吃芒果和菠萝。 We have watermelon juice, orange juice and cucumber juice. 有西瓜汁、橙汁和黄瓜汁。 They planted some watermelon. 他们种了些西瓜。

两句话是有区别的,第一句是:我(过去)种的那棵树(现在)已经比那房子高了。第二句是:我(过去)种了一棵比现在房子还高的树,显然后一句不成立。关键是要知道定语从句是来修饰一名词或代词的,要把从句译到这一词之前,但后一句,即你要问的那句可以改为 I planted a tree, which is taller than the house.这是一非限制性定语从句,主句与从句是并列关系。这时是可以的。译为:我(过去)种了一棵树,它(现在)已经比那座房子高了。
希望你能明白。
