May I have you attention please? I have few things to tell you. When you have class here in the language lab, please be here a little early. Change your shoes before enter the lab. Don’t bring anything here except your text books. When you are into, please don’t touch these machine without permission. Always do as the teacher tell you to. In class you should only speak the English, not Chinese. Recorders can be used make a copy of the listening materials. When class over, turn off your machines and leave the lab one by one.
That’s all. Thank you.May I have you attention please?中的you→your

(答案→)May I have you attention please?中的you→your 解析：【小题1】attention是名词，所以前面用物主代词your而不是人称代词you 【小题2】few表否定，a few才表肯定【小题3】上课用have a class【小题4】早一点用a little earlier表示，a little后面接比较级【小题5】before是介词后面接doing或者before是连词后面接句子，则在enter前面加you【小题6】后面没有宾语所以用in副词来表示【小题7】前面有these修饰复数名词，所以machine应该用复数machines【小题8】主语是the teacher单数第三人称形式，所以谓语动词应该用tells单三式【小题9】“说英语”表达方式为speak English，中间不加冠词【小题10】class主语后面缺少谓语部分，整句话是主系表结构，需补充be动词，所以加上is

我也是这个答案
