副词一般用来修饰“实意动词”（能够做出来的动作例,play,sing；当然think,like也算这一类）、“形容词”及“副词”.
the moon shone clearly.这里clearly修饰实意动词shone（shine的过去式）.
I have got many collections of snow globes .you may take (one) if you like.
泛指“一个”,其它不合题意.
I like the teacher (whose) classes are very interssting and creative.
如果把这个句子改成I like the teacher (the teacher's) classes are very interssting and creative.是不是更好理解呢?whose即表示“老师的”.
The population of China is larger than (that) of China.
that 本题最后一个词不应该是China.that指population,为了避免重复所以用that,且不是指同一个地方,所以不用it.
I find time (goes by) very quickly when I do something interesting.
find后面接“宾语从句”time是单三作主语,所以填goes
