题目内容
4．-I know Jack has already collectedthousands of stamps（成千上万的邮票）．-Yes，he's crazy about it．
分析 --我知道Jack已经收集了成千上万的邮票．
--是的，他对此很着迷．
解答 答案：thousands of stamps．
根据提示汉语结合语境推测句意是"我知道Jack已经收集了成千上万的邮票．"，设空处短语"成千上万的"表示一个不确定的数目，用thousands of，名词"邮票"为stamp，是可数名词，由于放在短语thousands of 后面所以用复数形式，故案是：thousands of stamps
点评 做这类题型，首先根据所给汉语明确句子所要考查的单词或短语的拼写，再结合相关语法知识对单词或短语做出形式上的变化．
