题目分析：
略。
选项分析：
A选项：划线部分最后的习惯搭配有误，我们通常会用“上升到一个等级（raise the levels to xxx）”，而不说“上升在一个等级上（raise the levels at xxx）”，也就是说把一个等级给升到什么地方，而不会用at。
B选项：Correct. 本选项在语法和逻辑上均是正确的。
C选项：介词短语at investing the new money需改为不定式短语to invest the new money，这点考查了不定式和ing的区别。用之于本题，eager的意思是“急切渴望”，显然对其宾语所讲的事件的约束力较强，因此，be eager后面要加to do而不能加at doing。
D选项：were not eager应该改成现在完成时have not been，这是因为这件划线部分的事情应该是到现在为止发生的事情，而不是在过去发生的事情。另外划线部分最后一个介词at应该改成to，该错误同选项(A)。
E选项：时态错误同选项(D)。介词短语at investing the new money需改为不定式短语to invest the new money，该错误同(C)。
were not eager应该改成现在完成时have not been，这是因为这件划线部分的事情应该是到现在为止发生的事情，而不是在过去发生的事情
