在浏览器窗口顶部，应该有一个标有 F ile的菜单.在该菜单下有一个 P rint菜单项.选择它.
如果没有可见的菜单，请查找带有打印机图片的工具栏按钮.
Up at the top of you browser window, there should be a menu labeled File. Under that there is a Print menu item. Select it.
If you don''t have the menu visible, look for a toolbar button with the picture of a printer on it.

We don''t do homework for people. You need to do your own homework, or tell your teacher you''re too dumb for the course.
