小题3: Wait a moment , please

小题5:open your e—mail program
1. 根据答句I’ m sending an e—mail to one of my good friends（我正在给我的好朋友们发邮件）可知，A是问B Xiaoming正在做什么，时态要一致，故用What are you doing now？
2. 从Could you please teach me how to do it ?（你能教我怎么发邮件吗）可知A不知道如何发邮件，故答案为：I don’t know how to send an e—mail。
3. 根据下文Well , I have finished sending it （我刚把邮件写完）可知B是叫A先稍等，故可填：Wait a moment , please。
4. 前面Is it easy to send an e—mail ?是个一般疑问句，从下面的显示来看，发邮件很简单，故用：Yes , it is 。
5. 常识题。讲的是发邮件的过程，首先要打开你的邮件程序，再点击，故用：open your e—mail program。
