????正確答案為A. as 。本題涉及到as作連詞的用法。

代詞。下面就as引導(dǎo)的各類從句 和慣用法，試作歸納，供同學(xué)們學(xué)習(xí)時(shí)參考。
??? 一、表示比較，意即"象……一樣"。
????1. Harry is unusally tall,as are his brothers.
??? 哈利也象他的弟兄們一樣，身材奇高。
??? 2.Army and people are as inseparable as fish and water.
??? 軍民關(guān)系，親如魚水。

起的從句強(qiáng)些。２）表語(yǔ)一般放 在本從句之首；如有可數(shù)名詞單數(shù)，前面也不
要冠詞。

??? Things are not always as they appear.
??? 事情不一定總是它們表現(xiàn)出來的那樣。
??? 七、引導(dǎo)定語(yǔ)從句。
??? １）as引導(dǎo)非限制性定語(yǔ)從句，常指主句所表達(dá)的整個(gè)事情，可置句首、
