Dear Linda,
I’ve got a problem and as I don’t know what to do,I think I’d write to you and ask for your advice.I have worked at a 51 factory for about two months till now.It’s a part-time job,so I only work in the evening.I’ve recently52 that one of my workmates is stealing.From time to time,I notice that he puts a piece of meat under his trousers just 53 he leaves the factory.Now the manager has found that things are 54 But he says that all this 55 after I started work.What should I do?Maybe I 56 tell that workmate I knew 57
he was doing.Or possibly I should go to the manager and tell him who was 58 meat.I think I’m
in a(n)59 position.Please tell me how I can solve this problem.I’d like to have your 60
Best wishes!
Yours,
Carl

指出错误说明为什么,

现在经理发现东西丢了,那应该在lose和miss中选择一个
两者都有“失去、遗失、丢掉、不见了”的意思.是普通词语,有时可以互换.但lose指失去某人或某物,不再拥有的意味,多含“不可复得”之意.而miss指在某时候或需要的时候却发现（发觉）遗失不见了某人或事物.
而且,什么东西丢了,应该用 sb. lose sth. 或者sth be missing
个人观点,望对你有帮助,谢谢!
