鲁教(五四学制)英语七下Unit4语法讲解及习题 be going to表将来、不定式作宾语 一、语法讲解 语法一:Future with be going to(be going to 表将来) 1. 核心含义 本语法主要用于谈论未来的计划、打算,也可根据现有迹象推测即将发生的事,语气侧重“有明确计划或依据”,常与梦想职业、新年决心、周末计划等话题结合。 例句: I’m going to work hard at maths.(我打算努力学习数学。) Are you going to read more books about IT?(你打算读更多关于信息技术的书吗?) I’m going to take art lessons.(我打算上美术课。) 2. 基本结构 be going to + 动词原形(do),其中be动词(am/is/are)的形式由主语的人称和数决定,不可遗漏或误用,具体对应如下: 主语人称/数 be动词形式 示例 第一人称单数(I) am I am going to be a writer.(我打算成为一名作家。) 第一人称复数(we) are We are going to make New Year’s resolutions.(我们打算制定新年决心。) 第二人称单/复数(you) are You are going to take acting classes.(你/你们打算上表演课。) 第三人称单数(he/she/it/人名) is John is going to read more books about IT.(约翰打算读更多关于信息技术的书。) 第三人称复数(they) are They are going to live in the countryside.(他们打算住在乡下。) 3. 句式转换 (1)否定句:在be动词后加not 结构:主语 + be + not + going to + 动词原形 原句:He is going to work hard at maths. 否定句:He is not(isn’t)going to work hard at maths.(他不打算努力学习数学。) 补充:am not 不可缩写,are not缩写为aren’t,is not缩写为isn’t (2)一般疑问句:将be动词提到句首,首字母大写,句末加问号 结构:Be + 主语 + going to + 动词原形? 原句:I am going to be an IT engineer. 一般疑问句:Are you going to be an IT engineer?(你打算成为一名信息技术工程师吗?) 肯定回答:Yes, 主语 + be. (Yes, I am.) 否定回答:No, 主语 + be + not. (No, I’m not.) (3)特殊疑问句:特殊疑问词 + 一般疑问句? 常用特殊疑问词:what(什么)、how(怎样)、when(什么时候)、where(哪里) 1.

When are you going to read more classics?(你打算什么时候读更多名著?)—I’m going to read them this weekend.(我打算这个周末读。) 4. 用法细分及例句 (1)表示“计划、打算、准备”做某事( 主观有安排) 1. Fu Xing is going to read more classics.(傅兴打算读更多名著。) 2. I am going to join the school music club.(我打算加入学校音乐俱乐部。) 3. Tina is going to practise her drawing skills every day.(蒂娜打算每天练习她的绘画技巧。) (2)表示“根据迹象推测”即将发生的事 1. Look at the black clouds. It is going to rain.(看那些乌云,快要下雨了。) 2. The sky is getting dark. We are going to go home soon.(天快黑了,我们很快就要回家了。) 5. 易错点提醒 易错点1:遗漏be动词或be动词与主语不一致(高频错误)。 错误:I going to be a doctor. / She are going to take art lessons. 正确:I am going to be a doctor. / She is going to take art lessons. 易错点2:be going to 后面接动词原形,不可接动名词(doing)。 错误:He is going to reading a book about AI. 正确:He is going to read a book about AI. 易错点3:特殊疑问句句式混淆,忘记将be动词提到句首。 错误:What you are going to do this weekend? 正确:What are you going to do this weekend? 易错点4:there be句型与be going to连用,结构为There is/are going to be...(简单补充)。 例句:There is going to be a class meeting tomorrow.(明天将会有一场班会。) 语法二:Infinitives as objects(不定式作宾语) 1. 核心含义 不定式(to + 动词原形,部分可省略to)放在及物动词后面,作该动词的宾语,即“动词 + to do sth.”(或“动词 + do sth.”),常与“想要做某事、希望做某事、计划做某事”等表达结合。 例句: What do you want to be when you grow up?(你长大后想成为什么?) I want to be a writer when I’m older.(我长大后想成为一名作家。) Try to set mini-goals to help you achieve your resolution.(努力设定小目标来帮助你实现决心。) 2. 基本结构 主语 + 及物动词(vt.) + 不定式(to do / do) 说明:不定式作宾语的核心是“及物动词”,不及物动词后面不能直接接不定式作宾语;重点掌握三类动词。 3. 动词分类及例句 (1)后接“to + 动词原形”的动词 核心动词:want(想要)、hope(希望)、plan(计划)、decide(决定)、try(努力、尝试)、learn(学习)、promise(答应) 1. I want to be a fireman when I grow up.(我长大后想成为一名消防员。) 2. She hopes to improve her English this year.(她希望今年提高她的英语水平。) 3. They plan to have a picnic on Sunday.(他们计划周日去野餐。) 4. He decides to take up a new hobby.(他决定培养一个新爱好。) (2)后接“动词原形”的动词(必须省略to ) 核心动词:let(让)、make(使、让)、help(帮助,可省可不省to) 1. Let me help you make a plan.(让我帮你制定一个计划。) 2. My teacher makes me work hard at English.(我的老师让我努力学习英语。) 3. She helps me (to) practise singing.(她帮我练习唱歌。)(to可省可不省) (3)后接“to do 或 doing”的动词 核心动词:like(喜欢)、start(开始) 1. I like to read books about IT.(我喜欢读关于信息技术的书。) 2. He starts to learn to cook.(他开始学习做饭。) 4. 句式转换 (1)否定句:在谓语动词(及物动词)前面加don’t/doesn’t(主语是三单用doesn’t,动词变原形) 原句:I want to be an actress. 否定句:I don’t want to be an actress.(我不想成为一名女演员。) 原句:He hopes to read more classics. 否定句:He doesn’t hope to read more classics.(他不希望读更多名著。) (2)一般疑问句:将助动词do/does提到句首(主语是三单用does,动词变原形) 原句:She wants to take art lessons. 一般疑问句:Does she want to take art lessons?(她想上美术课吗?) 肯定回答:Yes, she does. 否定回答:No, she doesn’t. 5. 易错点提醒 易错点1:混淆“带to”和“不带to”的动词,如let、make后面误加to。 错误:Let him to clean the room. 正确:Let him clean the room. 易错点2:want、hope等动词后面误接动名词(doing),忘记接to do。 错误:I want being a teacher. 正确:I want to be a teacher. 易错点3:help后面的to可省可不省,无需刻意添加或省略,两种形式均正确。 例句:She helps me carry the box. / She helps me to carry the box.(两种形式都对) 二、语法习题 第一部分:单项选择 从A、B、C、D四个选项中,选出可以填入空白处的最佳选项。 1. —What are you going to be when you grow up? —I _ be an IT engineer.
