what's the differents between assignment and homework?Thank

the differents of lives between the british and chinese high school students could be symbol as the paradise and hell.The Chinese high school is much harder,and more strict. The British high scool were easier,and relaxible.
The Chinese students both at school and home were around the books all the time.This cause the chinese students to have lack of physical strength,and poor adaptability.the chinese educational system cause the chinese students to have limit of thought,and idea.
The british students got more time to play and contact with sports,and society. the british students learn more about the real world early. the british educational system give the british students more chance to think more differently, the british students were more creative ,and got more chance to win a Nobel prize!

我觉得应该是This is a different kinds fo animal.
这句话的意思大概是:这是一只不同种类的动物.
如果kind of中的kind不加s,那么前面一定要有a,也就是a kind of,
如果没有a,那么一定是kinds of
而句子开头的This is a……中的a,修饰的是animal,所以animal不加s,意思是:一只动物

different kinds of是正确的,表示：不同种类.
different是形容词,不加s用的

differents应该为different,each dream is different from the others.

B

verb Transtive 是及物动词,后一个是不及物动词.
及物动词就是后面可以加一个名词如 I do my homework
而不及物动词就是不能加名词,如 I must go .
do 后有名词my homework
go 后没有名词.
