Question

You may use the room as you like,         you clean it up afterwards.

A．a(chǎn)s if

B．so long as

C．now that

D．a(chǎn)s far as

Answer 1

B

試題分析：考查連詞。A.as if似乎，好像B.so long as只要 C.now that=since，既然 D.as far as遠(yuǎn)及。句意：你可以隨便用這個房間，只要你過后把它打掃干凈。
點(diǎn)評：本題四項(xiàng)均是從屬連詞，引導(dǎo)狀語從句。尤其注意now that引導(dǎo)的是原因狀語從句，相當(dāng)于since，表達(dá)“既然”之意。
即學(xué)即練：He won't change his mind ______ you go and try to persuade him yourself.
A．Since    B．Until      C．a(chǎn)s if      D．even if
選D，考查 even if引導(dǎo)讓步狀語從句。
