Unit 3 Food matters 语法讲解及专练（含PPT解析）【外研2024版七下英语】

/ 让教学更有效 英语学科 Unit 3 Food matters 语法讲解及专练 系动词 语法精讲 系动词，是用来辅助主语的动词，本身有词义，但是不能直接作谓语，后面必须跟表语，常跟在系动词后做表语的有名词短语，介词短语，形容词。常考的系动词有：be， become， get， turn，grow，go, keep（保持）， seem（似乎，好像是）， smell， sound， taste， feel，look 等。 注意：系动词不能有被动语态，也不能用于进行时态。 【拓展】系表结构：有系动词的句子结构就叫做系表结构，用来说明物质的一个性质，而不是一个动作之类，。如 I am 、he is 等。我们最常见的be动词am、is、are都是系动词。此外我们学过的几个表示“变化”的词也是系动词-become, get, turn, go, grow等。还有两个表示“保持”的keep, remain，seem, stay也是系动词。 【辨析】become， get， turn，grow，go这几个“变化”的区别 ① become（较正式）和get（较口语）主要是指一个人暂时性的身心变化或永久性的自然变化。例become/get angry, mad, strong, cold, dark . ② go常指由强到弱，由好到坏的状态变化。 The food goes bad.食物变质（馊）了。 ③ go后面也可接人或事物颜色的变色，此时与turn的用法相同。 ④ 系动词turn后面多接表示颜色的形容词作表语，也可接表示天气的形容词，侧重“变得与以前完全不同”。 He went/turned blue with cold. 他冻得发青。 The leaves turn yellow in autumn. 树叶在秋天变黄。 ⑤ grow主要表示逐渐变化，强调变化的过程。 It began to grow dark。天渐渐变得黑了。 语法精练（共计50小题，每小题2分，总分100分。） 1.The dish smells delicious, but it ____a little salty.
