　　Ⅱ.单项填空

　　1．The reason why the goods are sold at such low prices is that the manufacturers are willing to ________ prices in return for big volume of purchases.

　　A．cast down　　　　　　 　B．break down

　　C．settle down D．bring down

　　解析：选D　句意：货物被以如此低的价格卖出的原因就是厂商愿意降低价格来换取大批量的采购。bring down"降低"，符合句意。cast down"使沮丧"；break down"分解"；settle down"安定下来"。

　　2．-He ________ love with Mary for 8 years up till now.

　　-They'll get married sooner or later.

　　A．has fallen in B．has been in

　　C．fell in D．is in

解析：选B　句意："到目前为止，他与玛丽相爱8年了。""他们迟早会结婚的。"fall in love with强调动作，不与表示时间段的状语连用；be in love with表示状态，可与表示时间段的状语连用，排除A、C两项；根据时间状语up till now可知用现在完成时，故选B。
