    關(guān)于Learning how to relax yourself is essential to being happy.解析說:is essential to ,to是介詞,所以加了being happy.但不是有詞組是It is essential to do sth.為什么這里就是essential加to do?

    優(yōu)質(zhì)解答
    being happy整個(gè)可以做sth,it is...這個(gè)固定用法并不適用于這個(gè)句子,整個(gè)句子主語是Learning how to relax yourself 謂語是is,然后to being happy是做賓補(bǔ),to要作介詞用,介詞后面動(dòng)詞為ing形式.那在it is essential to do sth里面其實(shí)真正的主語是 to do sth,這句話就是 to do sth is essential?
    現(xiàn)在的句子 sth is essential to sth ,然后to 是介詞,后面加ing?可以這么說。
