用文本框太麻烦
而且不容易对齐
还要一直添加
用表格最方便
插入,表格,就可以啦
写完后,把表格边框选为“无”
就OK啦
而且你可以一段一段翻译
对齐非常容易
如果表格中,你想要回车
别忘了是用“ALT+回车”
而不是简单的用回车
如果觉得我的答案好
要记得给我加分哦

C.Make your voice a little lower than normal. Listeners like to listen to a relatively(相对) deep voice.
D.When you talk, try to be as natural as possible. Don’t try to memorize your words and read or recite them to your audience. You can use short notes to help you remember the important points.
E. You should know you and most of the people you talk to are different in many ways. Some of them may not know what you are talking about. Then speak to them on their terms and in their languages.
F. Concentrate on what you want to say. If you are always paying attention to gestures(手势),you will feel uncomfortable.
G. It’s true that there are some differences between American English and British English, but they’ll not cause much difficulty for listeners, so just speak the way you’re used to.
