七年级英语下册Unit3语法讲义 系动词 一、什么是系动词? 在英语中,有些动词后面不能直接跟宾语,也不能单独作谓语,而是要在后面接形容词或名词等,用来补充说明主语的状态或特征。这类动词叫作 系动词。 最常见的系动词是 be(am/is/are/was/were)。例如: I am a student. (我是学生。) The sky is blue. (天空是蓝色的。) 除了 be 动词,还有一些感官动词和其他动词也可以用作系动词。 二、感官系动词 感官动词表示通过感官感受到的状态,后面常接形容词作表语。 系动词 含义 例句 feel 摸起来 This bed feels hard. taste 尝起来 The biscuits taste sweet. look 看起来 You look tired. smell 闻起来 The milk smells sour. sound 听起来 The idea sounds good. 小练习:用合适的感官系动词填空(feel, taste, look, smell, sound)。 1. The soup ________ delicious. I want more. 2. Your hands ________ cold. Put on your gloves. 3. That music ________ beautiful. 4. She ________ happy today. 5. The flowers ________ nice. 三、表示“变化”的系动词 有些系动词表示主语状态的变化,常译为“变得……”。 系动词 含义 例句 get 变得 It was getting very dark. become 成为,变得 Leaves become yellow in autumn. go 变得(常指变坏) The meat goes bad. 例句: He becomes excited before the match. (比赛前他变得兴奋。) The weather gets colder and colder. (天气越来越冷。) Milk goes sour easily in summer. (夏天牛奶容易变酸。) 小练习:用 get, become 或 go 的适当形式填空。 1. In autumn, the leaves ________ yellow. 2. Don’t eat the food. It ________ bad. 3. It ________ dark. Let's go home. 四、表示“保持”的系动词 有些系动词表示主语状态的持续,没有发生变化。 系动词 含义 例句 remain 保持 Her room remains clean and tidy. 例句: He remains calm in trouble. (遇到麻烦时他保持冷静。) The shop remains open until 10 pm. (这家店一直营业到晚上10点。) 小练习:用 remain 的适当形式填空。 1. The old man ________ healthy although he is 90. 2. Please ________ quiet in the library. 五、系动词的否定句和疑问句 对于 be 动词,否定和疑问直接在其后加 not 或提到句首: 肯定:She is happy. 否定:She is not happy. 疑问:Is she happy? 对于 其他系动词(feel, taste, look, smell, sound, get, become, go, remain),它们的否定句和疑问句要借助助动词 do/does。 结构: 否定句:主语 + do/does + not + 系动词原形 + 形容词 疑问句:Do/Does + 主语 + 系动词原形 + 形容词? 例句: The dishes do not smell very nice. (否定) Does he look worried? (疑问) The cake does not taste very good. (否定) Does she get angry? (疑问) Life does not remain the same. (否定) 小练习:将下列句子改为否定句或疑问句。 1. The soup tastes good. (改为否定句) → The soup ________ ________ good. 2. He looks tired. (改为一般疑问句) → ________ he ________ tired? 3. They get excited. (改为否定句) → They ________ ________ excited. 4. She remains calm.
