Because we’re cleverer than people. They have to work harder. 因为我们比人聪明。他们不得不更努力工作。 【知识点 1】clever adj. 聪明的，灵巧的，精明的 近义词：smart / bright 反义词：stupid / silly / foolish 比较级：cleverer 最高级：cleverest cleverly adv. 聪明地 cleverness n. 聪明 例：My sister was always a lot cleverer than I was. 我妹妹向来比我聪明许多。 Her cleverness seems to get in the way of her emotions. 她好像聪明有余，激情不足。 She would cleverly pick up on what I said. 她会非常聪慧地领悟我所说的话。 【知识点 2】have to 意为“必须，不得不”，后接动词原形。 第三人称单数 has to；过去时态 had to；将来时态 will have to。 We have to walk home. Jim has to stay at home and look after his little sister. 【辨析】have to 与 must have to 侧重客观上的“必须”，有时态和人称的变化，否定形式要借助助动词来构成，即 don't have to / doesn't have to / didn't have to / won't have to，意为“不必”。 must 侧重于个人意志和主观上的“必须”，无人称和数的变化，可用来表示现在和将来的时态，否定形 式是 mustn't，意为“禁止，不许”。 【知识点 3】work harder 意为“更加努力工作”，这里的 harder 是一个副词 hard 此处用作副词，意为“努力地”。harder 是 hard 的比较级。 We should study hard. 【拓展】 ① hard 可作形容词，意为“困难的；坚硬的”。意为“困难的”时，其同义词为 difficult，其反义词为 easy。 It's hard to answer these questions. 回答这些问题很困难。 The stones are too hard. 这些石头太硬了。 ② hard 作副词时, 还可意为“大量地；费力地”。 雨下得很大。 It's raining hard. 1．He isn’t as A．clever as you．What do you reckon?
