对话

A: Today we need to debate whether schools should ban smartphones. I'll support the ban, and I claim that phones do more harm than good in class.
　　今天我们需要辩论学校是否应该禁止智能手机。我将支持禁令，并且我主张手机在课堂上的弊大于利。
debate→v.辩论 | support→v.支持 | claim→v.主张 | ban→v./n.禁止

B: I'll oppose that view. Smartphones can be useful learning tools if we guide students properly.
　　我将反对这个观点。如果正确引导学生，智能手机可以是有用的学习工具。
oppose→v.反对 | guide→v.引导

A: My main argument is that phones distract students from class. There is plenty of evidence showing lower test scores when phones are allowed.
　　我的主要论点是手机会分散学生上课注意力。有大量证据表明允许使用手机时考试成绩更低。
argument→n.论点 | distract→v.使分心 | evidence→n.证据

B: That is a strong point. However, phones also help students access online dictionaries and educational videos.
　　这一点很强。然而，手机也帮助学生使用在线词典和教育视频。

A: But those benefits don't require phones in the classroom. Schools could provide tablets instead. And any policy without clear rules won't convince parents.

B: Fair enough. Nevertheless, banning phones may create tension between students and teachers.

　　为了说服听众，我会说：“如果我们真的关心学习，就应该限制干扰。”
persuade→v.说服 | audience→n.听众 | distraction→n.干扰

B: And to counter that, I would ask: "Shouldn't we teach students self-control instead of removing the tool?"
　　为了反驳，我会问：“我们难道不应该教学生自控，而不是移除工具吗？”
counter→v.反驳 | self-control→n.自控

语法讲解

【语法59】高级条件句与隐含条件

除了常见的 if 条件句，英语中还常用隐含条件、倒装条件句和混合条件句来表达假设与辩论。

类型 结构 例句
混合条件句 If + 过去时, would + have done（现在条件→过去结果）
If + had done, would + do（过去条件→现在结果）		 If I were rich, I would have bought that house.
If you had studied medicine, you would be a doctor now.
隐含条件（介词/副词） But for / Without + 名词 But for your help, I would have failed.（要不是你的帮助）
隐含条件（otherwise/or） otherwise / or + 主句 Hurry up, or we'll miss the train.
倒装条件句（正式） Were I... / Had I known... / Should you need... Were I in your position, I would accept.
Should you need help, call me.

注意： - 混合条件句的主从句时间不一致，需分别判断时态。 - Were I / Had I known / Should you need 是 If I were / If I had known / If you should need 的正式倒装，多用于书面或演讲。 - But for / Without 后接名词，表示“如果没有”。
