I find them very helpful in increasing my konwledge of English .这一 句那里错了.

问题描述:

I find them very helpful in increasing my konwledge of English .这一 句那里错了.

冰淇淋是对的.
没争议!!

I find they are very helpful in increasing my kowledge of English 这样是不是会更好些 ,那中说法好想没太听过

楼上说的不对,这里楼主的语法用错了.
这里是过去时,所以find应该改为found.
I found them very helpful in increasing my knowledge of English .
