考查数词辨析。
英语中一般直接用基数词表示年龄，不用序数词，可排除C项。
用“基数词+ years old”表示年龄时，注意years是复数形式，而“基数词—year—old”相当于形容词，year用单数形式。
根据句意语境，可知选A。
2．C解析：C【解析】句意：我认为我们迄今为止已经学了好几百个英语单词。
hundred“百”有数词修饰，表示具体数字时，不加s；表示约数时，与of连用，hundreds of好几百，故选C。
3．A解析：A【解析】试题分析：句意:-这台电脑多少钱？-大约三千元。
thousand 千，它主要有两个用法，一是和数词连用表示具体数量时，不用复数形式；二是构成短语thousands of ，成千上万的。
这里考查的是第一个用法。
故选A。
考点：考查数词。
4．C解析：C【解析】句意：——我听说今年九名外国学生将来我们的学校。
——对。
他们是第九批交换生。
第一空表示九名学生，故用基数词nine。
第二空根据定冠词the，表示第九批交换生，故用序数词ninth，故选C。
