Students use computers to... Language points 通过对比“过去（Then）”和“现在（Now）”来介绍电脑的发展。描述过去发生的事情或过去的状态，动词要用一般过去时（如 was, did not have, used）；描述现在的情况、客观事实或经常发生的动作，动词要用一般现在时（如 are, use）。在一般过去时中，含有实义动词的否定句要用助动词 didn't，且后面的动词要还原为原形。 Language points 句型结构： 过去肯定句：主语 + was/were + 其他. / 主语 + 动词过去式 + 其他. 过去否定句：主语 + didn't + 动词原形 + 其他. 现在肯定句：主语 + am/is/are + 其他. / 主语 + 动词原形/第三人称单数形式 + 其他. Language points as... as... 同级比较（描述事物的特征） It was as big as a room. And it was as heavy as four elephants. Language points as... as... 是英语中非常常用的同级比较句型，意思是“和……一样”。两个 as 中间必须使用形容词或副词的原级，不能使用比较级。 句型结构： A + be动词 + as + 形容词原级 + as + B. Language points 情态动词 must 的用法（表达规则、必要性与义务） A laptop must be used on a person's lap. Don't let your computer get too hot. Language points must 是情态动词，表示“必须、应该”，常用来表示规则或强烈的建议。情态动词最大的特点是没有人称和数的变化（不管主语是 I、He 还是 They，都用 must），且后面必须直接跟动词原形。 句型结构： 肯定句：主语 + must + 动词原形 + 其他. 否定句：主语 + mustn't (must not) + 动词原形 + 其他. Language points 动词不定式作目的状语（表达用途） Scientists used the early computer to do difficult maths tasks. Students use computers to write emails... People use the mouse to click and enter text. Language points 当我们想表达“用某物来做某事”（即表达目的或用途）时，通常使用 use... to do... 结构。这里的 to 是动词不定式符号，后面必须接动词原形。 句型结构： 主语 + use(s) + 名词(工具/物品) + to + 动词原形 + 其他. Language points 1.The first computer didn't have a mouse.
