    期中复习之单元语法精讲精练100题 (Unit 1-Unit 3) (时间:80分钟,满分:100分) Unit 1 The secrets of happiness 一般过去时 Unit 2 Go for it 不定代词 Unit 3 Food matters 系动词 一、一般过去时(Simple Past Tense) 1. 核心规则回顾 用法:描述过去发生的动作或存在的状态,常搭配过去时间状语(yesterday, last year, in 2020)。 动词变化: 规则动词:直接加-ed(played, watched)。 不规则动词:需单独记忆(go→went, eat→ate, see→saw)。 句型: 否定句:主语 +did not (didn’t) + 动词原形(He didn’t go home.) 疑问句:Did + 主语 + 动词原形?(Did you finish your homework ) 2. 易错点 动词未变过去式:She play basketball yesterday. She played basketball yesterday. 疑问句中误用过去式:Did she went to school Did she go to school 二、不定代词(Neither/None/Both/All/Either) 1. 含义与用法对比 代词 含义 适用数量范围 搭配结构 例句 both 两者都 两者 both + 复数名词 Both books are interesting. all 三者及以上都 三者及以上 all + 复数/不可数名词 All students passed the exam. either 两者中任意一个 两者 either + 单数名词 Either answer is correct. neither 两者都不 两者 neither + 单数名词 Neither shirt fits me. none 三者及以上都不 三者及以上 none of + 复数名词 None of the apples are fresh. 2. 特殊规则 both...and... /either...or... /neither...nor...: Both Tom and Jerry like cartoons.(两者都) You can choose either tea or coffee.(二选一) Neither henor I am wrong.(两者都不) none 与no one 区别: none 可指人或物(None of the food was eaten.) no one 仅指人(No one knows the answer.) 3. 易错点 Both of the answers is right. Both of the answers are right.(both + 复数动词) Either the teacher or the students is responsible. Either the teacher or the students are responsible.(就近原则) None of the money are missing. None of the money is missing.(不可数名词用单数动词) 三、系动词(Linking Verbs) 1. 核心功能 连接主语与表语(形容词/名词),描述状态或性质,不可单独作谓语。 常见系动词: be(am/is/are/was/were) 感官动词:look(看起来), sound(听起来), smell(闻起来), taste(尝起来), feel(感觉) 状态变化:become(变得), get(变得), turn(变成), grow(逐渐变得) 2. 用法规则 系动词 + 形容词(不可用副词修饰): The flowers smell sweet.( sweetly) She looks happy.( happily) 系动词 + 名词(表身份或性质): He became a doctor. This is a secret. 3. 易错点 The soup tastes deliciously. The soup tastes delicious.(形容词修饰系动词) She looked the picture carefully. She looked at the picture carefully.(实义动词需加介词) 一、单项选择(本大题共70小题,每小题1分,共70分) 1.They _____ a picnic last Sunday. A.have B.had C.will have D.are having 【答案】B 【详解】句意:他们上周日去野餐了。 考查时态。根据“last Sunday”可知,此句应用一般过去时,have a picnic“去野餐”,动词短语,have为动词原形,其过去式为had。故选B。 2.My family _____ a picnic in the park last Sunday. A.had B.have C.are having D.will have 【答案】A 【详解】句意:我的家人上星期天在公园野餐。 考查动词时态。根据“last Sunday”可知,本句是一般过去时,动词用过去式,故选A。 3.She _____ the piano at 9:00 am yesterday. ... ...
