1 2 Unit 3 Food matters 第2课时 Understanding ideas 5-8 3 语法专项 一层 句境练基础 二层 语篇练综合 4 语法专项 系动词 一、常见系动词的分类及含义 1.感官系动词 感官系动词包括 taste（尝起来）、smell（闻起来）、look（看起来）、feel （摸起来/感觉）、sound（听起来） 。它们用于描述事物给人的感官感受，后接 形容词等作表语，可生动展现事物特征。比如 “This ice-cream tastes sweet.” （这个冰淇淋尝起来很甜。），用 taste 描述味道；“The rose smells fragrant.” （玫瑰闻起来很香。），用 smell 描述气味；“The baby looks cute.”（宝宝看起 来很可爱。）用look 描述外观；“The silk feels soft.”（丝绸摸起来很柔软。）， 用feel 描述触感；“The music sounds wonderful.”（音乐听起来很棒。），用sound 描述声音感受 。 返回目录 5 2.变化系动词 become（变得）：强调事物从一种状态转变为另一种状态。如：When you cook scrambled eggs with tomatoes，the egg mixture becomes golden yellow.当你 做西红柿炒鸡蛋时，鸡蛋混合物会变成金黄色。 3.保持系动词 remain（仍然是；保持）：表示继续保持某种状态。如：The smell of coffee remained strong.咖啡的味道仍然很浓烈。 返回目录 6 二、系动词的语法特征 1.系动词后接表语 系动词不能单独作谓语，必须和其后的表语一起构成谓语部分。表语通常由形 容词、名词、介词短语等充当，用来描述主语的特征、状态等。例如“My sandwich tastes delicious.” 中，“delicious” 是形容词作表语，说明三明治尝起来的 味道；“The dish looks a kind of traditional food.”中“a kind of traditional food” 是名词短语作表语，描述菜的类别。 返回目录 7 2.系动词没有被动语态和进行时态 因为系动词主要是表示主语的状态、特征等，而不是一个具体的动作，所以不 存在被动和进行时态。例如不能说 “The soup is being tasted delicious.”，只能说 “The soup tastes delicious.”。 返回目录 8 微语篇练语法 阅读短文，用括号内所给词的适当形式填空。 Hello，everyone!
