 Unit 1 金牌导学案 Time to Relax 金牌导学案 金牌导学案 Period 3　Grammar Focus(4a－4c) 2 课堂小测 1 单元语法讲练 一、不定式（to do） 1．不定式作目的状语 （1）核心定义 不定式（to do）用来修饰谓语动词（说明动作的“目的”），相当于一个“副词”的功能。 单元语法讲练 Period 3　Grammar Focus(4a－4c) （2）常见用法 不定式（to do）意为“为了……”，常可转换为 in order to或so as to do（so as to 不用于句首）。 例如：She gets up early to catch the bus.她早起是为了赶公交。 →用“to catch”说明“gets up early”的目的。 I study hard in order to pass the exam.为了通过考试，我努力学习。 →用“to pass the exam”说明“study hard”的目的。 单元语法讲练 Period 3　Grammar Focus(4a－4c) （3）关键判断依据 去掉“to do”后，句子的“主语＋谓语”是完整的。比如 “She gets up early”（她早起）本身是完整句子，“to catch the bus”只是补充 “早起”的目的，这就是状语的作用。 2．不定式作宾语补足语 （1）核心定义 当句子中有 “主语＋谓语＋宾语” 后，宾语的动作或状态还不完整，需要用 “to do（或省略 to 的 do）” 来补充说明，这个 “to do/do” 就是宾语补足语（简称 “宾补”）。 单元语法讲练 Period 3　Grammar Focus(4a－4c) （2）常见结构与标志 常用 “谓语动词＋宾语＋to do”（部分动词可省略 to），常见动词分两类： 动词类型 代表动词 结构特点 例句 接“to do”作宾补 ask（要求）、tell（告诉）、want（想要）、teach（教）、encourage（鼓励）、advise（建议） 必须带“to” My mom asks me to clean the room.妈妈让我打扫房间。 →宾语“me”的动作是“to clean”，补充说明我要做的事。 单元语法讲练 Period 3　Grammar Focus(4a－4c) （3）关键判断依据 去掉 “to do/do” 后，句子的 “宾语” 会显得 “意义不完整”——比如 “My mom asks me”（妈妈让我），没说 “让我做什么”，加上 “to clean the room” 才完整，这就是宾补的作用。 动词类型 代表动词 结构特点 例句 接“do”作宾补（省略to） let（让）、make（使）、have（让）、see（看见）、hear（听见）、watch（观看） 主动语态中省略 “to”，被动语态需补回 “to” He let his son play outside.他让儿子在外面玩。 →宾补“play”省略“to”，补充儿子的动作。 被动：His son was let to play outside.（需补回“to”） 单元语法讲练 Period 3　Grammar Focus(4a－4c) 一、判断下列句子中不定式的作用。（作宾语补足语或目的状语） 1．She asked me to open the window.　　　　　 ______________　　　　　　　　　 2．He went to the library to borrow some books. ______________ 　　　　　 3．The teacher told us to be quiet in class. ______________ 　　　　 4．She went to the store to buy some food. ______________ 　　　　 5．My mother wants me to learn the piano. ______________ 　　　　 宾语补足语 目的状语 宾语补足语 目的状语 宾语补足语 课堂小测 Period 3　Grammar Focus(4a－4c) 二、请从方框内选择适当的词并用其正确形式填空，使文章完整、连贯。注意每空一词，每词仅用一次，有两词为多余项。 My twin brother and I look alike, but we are so different in our personalities and hobbies.I am very active and outgoing, and I often meet my friends in the park to 　1　 football or tennis. 1._________ about 　countryside 　at　 instead　 difference　 or　 Saturday　 all　 play 　 go　 a　 chat play　 课堂小测 Period 3　Grammar Focus(4a－4c) My brother joined us to play football once 　2　 twice, but he decided not to come after that.He doesn't like sports very much! 　3　， he prefers staying at home.He enjoys watching movies, listening to music, reading books, and 　4　 with friends online.Our parents were a little worried 　5　 him staying home too much. 2. _________ 3. _________ 4. _________ 5._________ about 　countryside 　at　 instead　 difference　 or　 Saturday　 all　 play 　 go　 a　 chat or Instead chatting about 课堂小测 Period 3　Grammar Focus(4a－4c) They also wanted us to spend more time together as a family.So, now they let us do our favourite activities on 　6　.But on Sundays, we all 　7　 on an outing together.Last Sunday, we visited a small museum in the 　8　. 6._________ 7._________ 8.___________ about 　countryside 　at　 instead　 difference　 or　 Saturday　 all　 play 　 go　 a　 chat Saturdays　 countryside　 go　 课堂小测 Period 3　Grammar Focus(4a－4c) It was an interesting experience for 　9　 of us.My brother even said he had a great time.I think it's good to have 　10　 interests, but it's also important to share some time with family. about 　countryside 　at　 instead　 difference　 or　 Saturday　 all　 play 　 go　 a　 chat 9._________ 10._________ different all　 课堂小测 Period 3　Grammar Focus(4a－4c) 重点知识积累（英译汉） 1．alike _______________　　　　　　　　　　　　　　　　 2. be worried about _______________　　　　　 相像　 担忧；担心 课堂小测 Period 3　Grammar Focus(4a－4c) 三、语法选择。 Lucy always looks forward to weekends—she can enjoy different leisure activities.
