真诚地希望得到诸位的帮助，谢谢你们。

1/可以改写为only some students show interest in ...
这里要注意be interested in 的interested是个过去分词做的表语，而show interest in 中的interest则是show 的宾语，是个名词。所以，你的改写不正确。
改成not all students have interest in 就可以了，
2.题目本身句子有逻辑错误，as a result of是由于的意思，后面接原因而不是接结果，所以题目本身意思就错误的成为他们努力工作，由于他们成功了。
They succeded because worked hard.句子结构正确，后半句省略了they 。
3、你的改写正确。注意sb run out of sth,sth run out这两个短语。
