单选题18.I will not spend so much money on that fur coat, for I don't think it is______.
【正确答案】
A
【答案解析】be worth doing sth是固定用法,意思是“值得做某事”,worth是介词,后面多跟名词或动名词,不跟不定式,例如:This coat is worth the money.这件大衣的确值这些钱。worthy是形容阋,作表语时跟介词of连用,例如:That is very worthy of our attention.那件事很值得我们注意。另外,worthy后面也可以跟不定式,例如:He is worthy toreceive the honor.(=He is worthy of the honor.)他应得到这个荣誉。
