解题思路： The centre has 300 scientists devoted to finding measures that will stop desertification. devoted 在句中用作后置定语，修饰scientists. 整个句子等于The centre has 300 scientists who are devoted to finding measures that will stop desertification. be devoted to : 致力于--- , to 为介词，所以是finding ，而不是to find. 再举个例子：The school has 200 students interested in music. =The school has 200 students who are interested in music.
解题过程：
同学你好，如你所言，该题应该是devoted,而非devoting.
