1.
你感觉一下下面这两个句子的感觉
i have a skirt similar to yours.
my skirt has a similar design as yours.
当similar做名词的时候接to
当similar做形容词的时候接as
i have a skirt similar to yours 此时是名词
my skirt has a similar design as yours 此时是形容词 用来形容design的
2.l love swimming,说的是游泳的这个特定动作.口语中可以这么说,但是并不代表这个说法是正确的.
I love to swim,说的是习惯性的喜欢,我喜欢游泳.这个说法是技术上最标准的说法.
你可以体会一下,i love to eat,和i love eating的感觉,love doing something给人的感觉就是我就喜欢这个特定的动作.
3.it wasn't long before he left in a hurry,这个是说他很快就离开了,你可以先把in a hurry去掉来看这个句子,it wasn't long before he left,意思就是说他没多久就离开了.it wasn't 形容的是他在离开前的时间.
同样你如果说it wasnt long after he left 感觉这个话没有说完,因为他离开后的时间段到现在都还没有结束一直在进行着,那么就不应该是not long 是很long.如果你加上 it wasnt long after he left that Lucy called me就可以了,意思是说他离开后不久lucy就打电话给我了.
上面说过了 it wasn't说的是他离开前的时间段 C里面的then完全把意思改变了 而且then 的前面和后面都接动作句子 比如 he fell down then broke his legs 或者 i went to China then fell in love with it.而it wasnt long不是动作句子
同样when前后接的句子应该是 比如
it was 1994 when John married Mary.
it wasn't 1994 when John married Mary.
或者
i was doing homework when my brother called me.
i wasn't doing homework when my brother called me.

everything is serious,isn't it 是反问句 not 加在了is的后面 构成反问
nothing is serious,同样 把not加在is后面 构成反问句 isnt' it
但如果是not everything is serious的时候,反问就说 is it,因为前面已经有一个not了 做一后面反问的时候不加not了
反问句的not是加在你前面那个be动词的后面 跟be动词前面的词没有关系
但是这里有个例子
i have never smoked before,have
这个时候不是把not加在have的后面是因为
i have never 可以看做 i have not yet,i havent yet 已经有not 在have的后面了 所以反问的时候把not 去掉
