Unit3 语法2024-2025学年外研版英语七年级下册

外研七下新教材Unit3 语法——系动词 系动词，也称为连系动词，是用来连接主语和表语的动词。它们本身有词义，但不能单独用作谓语，其后必须跟表语，构成系表结构说明主语的状况、性质、特征等情况。跟在系动词后做表语的有名词短语，介词短语，形容词。 系动词的分类： （1） be 动词：用来表示主语的状态。 She is a teacher.她是一名教师。 He is so angry. 他很生气。 Mike is in the classroom. Mike在教室里。 （2） 感官动词：表示感觉和知觉的系动词，后跟形容词等构成系表结构。感官动词主要包括look看起来，smell闻起来，taste尝起来，sound听起来，feel摸起来 You look tired. 你看起来很累。 This cloth feels soft. 这布摸起来很软。 The idea sounds great. 这个主意听起来很棒。 The biscuits tastes sweet. 饼干吃起来甜甜的。 The milk smells sour. 牛奶闻起来有股馊味。 · 注意事项 ① 感官系动词常用物做主语，feel，look等的主语既可以是人，也可以是物。 ② 感官系动词没有被动语态，且不能用于进行时态。 ③ 包含感官系动词的句子变否定句和一般疑问句时，要借助于助动词do, does, did等。 （3） 变化系动词：表示主语变成什么样，主要有get, turn, become, go. · get‌多用于口语，强调逐渐变化的过程，常接形容词的比较级形式。 The sky gets darker every minute. 天每分钟都变得更暗了‌。 · ‌turn‌常用于描述颜色和天气的变化，强调变化的前后对比。 The sky turned red at sunset. 夕阳时天空变红了。 · ‌become‌较为正式，可用于描述各种状态的变化。 He became a successful businessman. 他成为了一名成功的商人。 · ‌go‌常用于描述从好变坏的过程 The meat went bad. 肉变坏了。 （4） 持续系动词‌：用来表示主语继续或保持一种状况或态度，主要有keep, remain, stay He always keeps silent at meeting. 他开会时总保持沉默。 Her room remains clean and tidy. 她的房间一直保持干净整洁。 【练习】 1. —Daniel, try this strawberry cake. — It ________ delicious.
