Question

1．他太虛弱了，讓他一直在電腦前工作是不可能的．
He isso weak that it's impossible to keep him working in front of the computer．

Answer 1

分析 so weak that it's impossible to keep him working．

解答 答案：so weak that it's impossible to keep him working．這里是說(shuō)客觀事實(shí)用一般現(xiàn)在時(shí)，表示如此…以致于，用so/such…that，這里是用形容詞weak，表示如此虛弱，故用副詞so來(lái)修飾weak，故so weak that，表示做某事是怎么樣的用it作為形式主語(yǔ)，動(dòng)詞不定式作為真正主語(yǔ)的句型it's+adj+to do sth，形容詞不可能的impossible，讓某人一直做某事keep sb doing sth，故 keep him working，故答案是so weak that it's impossible to keep him working．

點(diǎn)評(píng) such…that作"如此…以致"解，連接一個(gè)表示結(jié)果的狀語(yǔ)從句．與so…that 意思相同，但用法不同．如：so…that這一結(jié)構(gòu)中，so后邊可加形容詞或副詞，
而such后邊要用名詞（這個(gè)名詞前面可以帶形容詞，也可以不帶）He has made such great progress that the teachers are pleased with him．
