请大家帮我汉译英一些句子啊

【前言】讲课用啊，那可要口语化一些哈。
【翻译】
1. Look at my mouth carefully.
2. Now, I'll make a correction.
3. Please make a self-introduction one by one.
4. You may tell us your name, age and hobbies, things like that.
5. Now listen to me carefully, while paying attention to the performance in your books.(?)
6.Well, I need a group of boys and a group of girls to come here.
7. What color is it, boys and girls?
【说明】有的意译，有的根据课堂环境加了一些成分，如最后一句。

【翻译】stands up：起立；站起来。
【说明】一般用祈使句：Stand up!(起立！)
【尾声】多提宝贵意见！

1 Please notice my mouth.
2 I will correct my mistake.
3 Please do self introduction one by one.
4 You can give us an introduction such as your name,age,habbit est.
5 Please listen to me carefully.while you are listening,you should pay attention to the pictures.
6 Now I would like to invite some girls and boys to show in front of us.

最后那该是stand up吧，最常用的意思是起立，还有支持某人观点的意思。
