The test is easy enough for him (to do).為什么不是to do it,請詳細解釋一下，并說明考點，謝謝!

熱心網友

do 的邏輯賓語是 the test , 若再加 it 就重復了考點就是 sb is + 形容詞 + enough to do sth sth is enough for sb to do He is old enough to understand it. The book is easy enough for him to understand.

熱心網友

it代的test 所以do后沒必要再加it謝謝不知我的回答你滿意嗎

熱心網友

就是這樣說的啊,it是省略的,be+adj.+enough (for sb.)to do
