Cut out pieces of card with a pair of scissors. cut out 剪下 e.g. There is an interesting article in the newspaper and I'll cut it out. 报纸上有一篇有趣的文章，我要把它剪下来。 拓展：cut out 除了“剪下”还有“删除”、“关掉”、 “停止，戒除” 等意思 e.g. You should cut out the word. 你应该删掉这个词。 e.g. Can you cut out the machine. 你能关掉这台机器吗？ e.g. I decide to cut out smoking and drinking. 我决定戒烟戒酒。 23002 祈使句 当我们向他人发出命令、提出要求或建议时，常使用祈使句。如： Be quiet, please! 请保持安静！ Don't be late again! 不要再迟到了！ 注意：祈使句的主语通常不明确表示出来。 23002 祈使句的肯定形式以动词原形开头；其否定形式是在动词原形前加do not / don't。 为了显得更为客气和礼貌，我们常在祈使句中加上please。当please用在句末时，必须用逗号与其余部分隔开。如： Please pass me the ball. 请把球传给我。 Open the window, please. 请把窗户打开。 23002 用should和had better提建议 当我们给他人提建议时，可以用had better和should，表示“最好”或“应该”做某事，had better的语气比should强一些。如： You had better water the flowers as soon as possible. 你最好尽快给花浇水。 All of us should take part in this activity. 我们每个人都应该参加这个活动。 23002 注意：had better和should都是情态动词，后接动词原形， 而且均没有人称和数的变化。 had better中的had常缩略为'd。如“ We'd better leave before it rains. 我们最好在下雨前离开。 had better和should的否定形式是：had better not和should not / shouldn't。如： You had better not play computer games now. 现在你最好别打电脑游戏。 He shouldn't be late for school again. 他不该再迟到。 23002 当堂检测 翻译下列句子。 1. 你总是犯一些错误。你应该更认真一点。 2. 你看上去很累。你最好休息一下。 3. 不要再上学迟到了！ 4. 请安静！ You always make some mistakes.
