英語問題

1.as, which 引導(dǎo)的非限定性定語從句，as和which可代整個主句，相當(dāng)于and this或and that。As一般放在句首，which在句中。
我再補充下，就是不可以說 which is known，只可以說as is known
先行詞前面有最高級用that 不可以用which
還有先行詞是抽象詞的比如information 等等也只能用that，而且用了that，主從句間 不可以有逗號
2.pleasure是名詞，pleased是形容詞
it's my pleasure
i am pleased

你第一個問題很難答，這得根據(jù)情況了。
如a flim that is directed by 是物用了that.
the way which brings you home 這就用which，用that也可以。
這個問題就要你自己做題是根據(jù)語境了。

would like to do sth.
would rather do sth. than do sth.
had better do sth.
feel like doing
would you like 就是would like to do

pleased 是形容詞，解釋為開心的，跟在am，is，are ，feel等類似詞后面
pleasure是名詞，解釋為樂意做的事情。如It is my pleasure.這是我樂意的事，可翻譯為 不用謝。

as, which 引導(dǎo)的非限定性定語從句，as和which可代整個主句，相當(dāng)于and this或and that。As一般放在句首，which在句中。

would like doing
would rather do
had better do
feel like doing
would you like to do/doing

pleased是形容詞
pleasure是名詞

1.通常情況下，which和that可以通用，但主語被the only，the same，以及形容詞和副詞的最高級修飾時（先行詞前有這些），只能用that，當(dāng)先行詞前有介詞時，只能用which，例如in which，介詞提前。
2.would like to do/would rather do/had better do/feel like doing/would you like to do.
3.pleased 基本翻譯
adj 高興的
pleasure ['ple??]
基本翻譯
n. 高興,愉快
my pleasure:我的榮幸!
