Question

If ________, please pay a visit to me and have a further discussion of the issue.

A．you are convenient	B．it is convenient
C．it at your convenience	D．it is convenience

Answer 1

B

試題分析：句意：如果方便的話，請(qǐng)來看望我，我們對(duì)這個(gè)問題進(jìn)行一次更深地探討。at your convenience在你方便的時(shí)候，選項(xiàng)C沒有謂語動(dòng)詞；convenience 是名詞；convenient不能用人做主語，一般需用it做主語，it is+形容詞convenient；故選B。
點(diǎn)評(píng)：本題難度適中。固定句式是近幾年的高考的熱點(diǎn)，不僅在單選中考查，還會(huì)出現(xiàn)在完形和短文改錯(cuò)中。
即學(xué)即練：I will come when________ to you.
A. you are convenient                  B. it is convenient
C. it at your convenience             D. it is convenience
解析：B。句意：我會(huì)在你方便的時(shí)候來的。
