Because I always make digital payments, I never carry my wallet. as = because（语气较弱），引导原因状语从句 I was so tired that I gave up on cooking. I was too tired to cook. so...that... = too...to...（主语一致时可转换） They stood still instead of moving across a screen. They stood still and did not move across a screen. instead of doing = and not do Phones have an effect on our life. Phones affect our life. have an effect on = affect（动词） My mum asks me to read more books.

My parents allow me to use the phone. let sb. do sth. = allow sb. to do sth.（让/允许某人做某事） 四、语法精讲（Grammar） 4.1 什么是宾语补足语 【中考考频】动词不定式作宾语补足语是中考高频考点，集中在单选、完形和句型转换中。重点考查 make/let sb. do（省略 to）的用法。 宾语补足语（Object Complement）用来补充说明宾语的动作、状态或身份，使句意完整。基本句型为：主语 + 谓语动词 + 宾语 + 宾语补足语。 动词不定式（to + 动词原形）作宾语补足语时，用来表示宾语要做的动作。例如：My mum asks me to read.（me 是宾语，to read 是宾补，说明 me 要做的事。） 4.2 常见接"to do"作宾补的动词 这类动词后接"宾语 + to do"，to 不可省略。常见动词按意义可分为以下几组： 动词 含义 用法 例句 ask 要求 ask sb. to do sth. 要求某人做某事 My mum asks me to read more books. tell 告诉；吩咐 tell sb. to do sth. 吩咐某人做某事 The teacher told us to finish the homework. allow 允许 allow sb. to do sth. 允许某人做某事 My parents allow me to use the phone. encourage 鼓励 encourage sb. to do sth. 鼓励某人做某事 The teacher encourages us to try new apps. invite 邀请 invite sb. to do sth. 邀请某人做某事 She invited me to join the club. expect 期待；预料 expect sb. to do sth. 期待某人做某事 I expect you to be on time. advise 建议 advise sb. to do sth. 建议某人做某事 The doctor advised me to rest. want 想要 want sb. to do sth. 想要某人做某事 I want you to help me. wish 希望 wish sb. to do sth. 希望某人做某事 I wish you to be happy. order 命令 order sb. to do sth. 命令某人做某事 The officer ordered them to stop. warn 警告 warn sb. (not) to do sth. 警告某人（不）做某事 The sign warns us not to touch it. teach 教 teach sb. to do sth. 教某人做某事 My father taught me to ride a bike. 4.3 省略 to 的情况：使役动词 使役动词 make / let（使/让） 公式：make/let + sb. + do sth.（省略 to）。使役动词后接动词原形作宾补，to 必须省略。 动词 用法 例句 make make sb. do sth. 使某人做某事 Apps make us live more conveniently. / Sad movies make me cry. let let sb. do sth. 让某人做某事 My parents let me use the phone after dinner. 4.4 help sb. (to) do sth.：to 可省可不省 help 后的宾语补足语用带 to 的不定式，但 to 可以省略，意义不变。美式英语中常省略 to。 例句：Smartphones help us (to) connect with others. / The app helps me (to) save time. 两种写法都正确。 拓展：help (to) do sth. 中的 to 也可省略。例如：The new app helps (to) make life easier. 4.5 高频考点总结 1. 使役动词 make/let + sb. + do（主动省 to）：My parents let me use the phone.（正）My parents let me to use the phone.（误） 2. ask/tell/allow/encourage/invite/want 等动词后 to 不可省略：The teacher encourages us to try.（正）The teacher encourages us try.（误） 3. help sb. (to) do 中 to 可省可不省：The app helps me (to) save time. 两种写法均正确。 4. 否定形式：not 放在 to 之前。如 ask sb. not to do / tell sb. not to do / warn sb. not to do。My mum asks me not to play games too long. 5. 区别"to do 作宾补"与"to do 作目的状语"：作宾补紧跟宾语，作目的状语修饰整句。I went to the store to buy an app.（目的状语）I asked him to buy an app.（宾补） 五、单元话题写作（Writing） 5.1 写作任务：介绍一款未来数字产品 本单元写作任务是以"Digital life in the future"为主题，介绍一款你设计的未来数字产品（如 smart life helper 智能生活助手），说明它的功能、使用方式和给生活带来的改变。要求：80-120词，结构清晰，可适当使用动词不定式作宾补。 5.2 写作框架 段落 内容 可用句型 示例 第一段 引出产品名称与定位 I would like to design... / It is a kind of... / ...will help people to...

It will make life easier, save us time, and connect us with others. I hope my dream will come true in the future. 5.4 写作好词好句积累 类别 表达 适用场景 介绍产品 I would like to design... / It is a kind of... / It looks like... 引出产品名称、外形与定位 描述功能 It can help sb.

(to) do 不接 doing；C 正：let sb. do sth. 让某人做某事，省略 to；D 错：ask sb. not to do，not 后应有 to。 26 allow; me; to let sb. do sth. = allow sb. to do sth.（让/允许某人做某事），allow 后接带 to 的不定式。 27 Because as = because（语气较弱），引导原因状语从句。注意首字母大写。 28 too; to so...that... 与 too...to... 转换：so + adj. + that 从句 = too + adj. + to do（主语一致时）。too tired to cook = 太累而不能做饭。 29 affect have an effect on = affect（动词），主语 Phones 复数，affect 用原形。 30 did not play instead of doing = and not do（用 and 连接两个并列动作，not 后接动词原形）。did not play = 没有玩。 学科网（北京）股份有限公司 $
