题目内容
19．The Changjiang River is the third _____in the world．（ ）| A． | long river | B． | long rivers | C． | longest river | D． | longest rivers |
分析 长江是世界上第三最长的河流．
解答 答案：C
根据"in the world"可知，此处是在拿长江跟世界上所有的河流相比较，故这里应该用形容词的最高级形式，故排除AB；再由主语"The Changjiang River"为单数可知，这里的"river"也应为单数，故排除D，答案为C
点评 做这样的题时，要先根据句中词语确定形容词的适当形式，然后根据选项选出正确答案．
