Complete these sentences with these words.;4.Listen and read;;;;;Listen again and answer:;1. Finally, turn on the computer. 最后，打开电脑。 (1) turn on打开；turn off关闭。 (2)on和off都是副词。若代词作宾语，要放在动词和副词的中间；而名词作宾语时的位置比较灵活，可放在中间，也可以放在后面。; 完成句子 ①请打开书翻到第20页。 Please ________ your books and turn to Page 20. ②请关上电视, 让我们出去散散步吧。 Please ________ ________ the TV set. Let’s go out for a walk. 【点拨】①open ②turn off ;2. First, open a new document. 首先打开一个新建文件夹。 (1)本句为祈使句，省略了句子的主语you, 句中的谓语动词用原形，表示命令、邀请、请求等语气。 (2)first“首先，第一”，是one的序数词。 first (首先), next (然后，其次), then (然后), finally (最后)是表示顺序的副词。在英语中，我们可以在句首加这些词来表示动作的先后顺序。 这四个词的先后顺序是： first→ next→ then→ finally ; ①Open the door, please. (改为否定句 ) ________ ________ the door, please. ②先打开一个新建文件夹，然后把你的作业写在新文件里。 ________ , open a new document. ________ , write your homework in the new document. 【点拨】①Don’t open ②First, Next/ Then (1)祈使句由肯定句变为否定句时往往在动词之前加don’t构成否定句。(2)Then, next都表示接在某种动作或情况之后，它们单独使用时都可放在first后面。; 3. 特殊疑问句 = 特殊疑问词(What, Where, When, Which, Who, How …) + 一般疑问句 1.
