参考答案及解析
1. A错，应改为made it possible。it是形式宾语，真正宾语是to引导的不定式结构。
2. B错，应改为have been given。根据句意，顾客应该是被给予找回的钱，所以应该用被动语态。
3. C错，应改为the larger。因为前面提到有两个基金（funds），两者中较大的应该用被动语态。
4. A错，应改为that。引导同位语从句应该用that。
5. A错，应改为little evidence。evidence是不可数名词，不能用few修饰。
6. C错，应改为enjoy。help sb. do sth. 是固定搭配。
7. C错，应改为are confused。confused是过去分词，指被弄糊涂了，符合句意；confusing是现在分词，指使糊涂。
8. D错，应改为would have put。跟过去完成时搭配的虚拟语气应用could have ＋done的形式。
9. C错，应改为shaking。shaking hands和going into the kitchen是介词of的并列宾语，形式应该一致。
10. C错，应改为live。alive指活着的，live指实况、现场（转播）。
