帮忙改写一下.. 英语解释句子.

在JIM班里没人比他歌唱的更好了。
JIM在他班里唱歌最好了。

Jim is the best singer in his class.
No one sings better than Jim in his class.
Jim is the top singer in his class.
Jim sings better than any other one in his class.

Jim sings best in his class.

Jim sings best in his class.
Jim sings better than anybody else in his class.
Jim sings better than any other people in his class.
None of the people sings better than Jim in his class.

从语义指向看 in his class 既可以指向 nobody 也可以指向 Jim

假设这个虚指的nobody是A 那么句中所指的class跟A和Jim将有如下三种可能：

1.A is in the class ， Jim is not in the class.

2.Jim is in the class , A is not in the class.

3.A and Jim are in the same class.
