总之，which与as引导定语从句的区别要在实践中多体会，体会多了，才能正确运用

The shed in our garden, in which we often played, has lasted for a long time.我们经常玩耍的花园里的那个棚子，已经有很长时间了。

The Thames, which is now clean enough to swim in, was polluted for over a hundred years.泰晤士河，现在已经很干净，可以在里面游泳，它曾被污染了一百多年。

As was natural, this inordinate hope was followed by an excessive depression.这种过分希望之后，接着是极度的沮丧，是很自然的事。
