1．—What do you think of the furniture on sale？
—Pretty good. But _______ what you bought with the samples, I don’t think it _______ the money. (河南)
A．comparing；worth B．compared；worth
C．compare；worthy D．comparing；value
答案：A
解析：
——你认为正在出售的这件家具怎么样？——很好。但把你买的那件和这些样品相比较，我想这件不值那么多钱。设空处所在句子既无并列连词又无从属连词，由此可知第一空考查分词作状语，排除C项；主句主语I与compare之间为逻辑上的主动关系，排除B项；It is worth后可跟价钱或表价钱的名词，故选A项。
2．You may use the room as you like ________ you clean it up afterwards. (北京)
A．so far as B．so long as
C．in case D．even if
答案：B
解析：
你可以任意使用这个房间，只要你之后打扫干净。so far as就……而言；so long as=as long as表示唯一条件“只要”：in case以防，万一；even if即使，尽管。
3．—Why does the lake smell terrible？
—Because large quantities of water ________.(福建)
A．have polluted B．is being polluted
C．has been polluted D．have been polluted
答案：D
解析：
——这湖水怎么这么难闻？——因为大量的水已经被污染了。本题考查时态、语态及主谓一致问题。water与pollute为被动关系，故排除A项；B表“正被污染”，故排除；large quantities of后加名词，谓语动词应与quantities保持一致，故排除C项，答案为D项。
