综合考察

now many Chinese go to America,because they think America is a place where hard work is( ) A reliable B awarded Crewarded

解题思路： 如下
解题过程：
选C。
reliable 是形容词，意思是“ 可靠地,可信的” ，而该句的主要是hard work,选A意思不通顺；
用作动词时，award的意思是"授与"、"颁发"、"判给"；reward则表示"报答"、"酬谢"之意。例：

He was awarded the first prize for Outstanding Industrial Design．

他获杰出工业设计一等奖。

We judge awarded him twenty thousand dollars as damages．

法官判给他二万元作为赔偿费。

You should reward them according to their deserts．

你应该对他们论功行赏。

Is that how you reward me for my help？

你就是这样来报答我给你的帮助吗？
句意是：现在许多中国人都去美国，因为他们认为美国是一个付出努力就有所回报的地方。根据句意可知，应该用reward的被动形式，表示“努力被回报”之意。
最终答案：略
