问题描述:

1.For breakfast he only drinks juice from fruit____ on his farm.
A grown B growning c being grown
答案给出的是 A,但我觉得为什么B 不行啊,水果不是主动生长吗?为什么要用过去分词?grown不是也有生长的意思吗
2.I have been working all day,but I feel as if I___nothing.
A.have achieved B had achieved C achieved 希望有讲解,
3.---What have you been doing recently?
-----I___ a trip to shanghai and have just returned.
Ahave taken B took
B 为啥 A不行,已经对现在造成影响了啊,

1 水果是被人种植 此处的GROW 是种植的意思 2 A 时态一致 3 have just returned标明已经回来 TAKE A TRIP 在此动作之前

1, 过去分词做定语2 AS IF+ 虚拟语态(过去+HAD DONE//现在+DID)ACHIEVEVED
3 通过AND HAVE JUST RETURNED 知道,前面动作发生了,故过去时

1 选A。过去分词作定语,水果是"he"种在农场的,要用被动态。
2 选B。虚拟语气。
3 选B。跟后面半句and have just returned有关,后面是现在完成,前面要用过去式。
其实太分析语法没什么大用,还是多读,培养语感更事半功倍。

我也很想帮你,可是我并没有学这些类容,抱歉!

1.A过去分词表状态,作定语,跟主被动无关
2.虚拟语气
后面时态比前面要早,所以B
3.这是一个口语对话
想回答我去了上海,仅仅是想表示过去干什么了
跟现在时无关
而且后半句也给了提示已经回来了
