语 境 自 主 领 悟 先观察原句 ①Both of these medicines have proved beneficial to mankind since they were invented. ②Within a short time，aspirin became the best-selling medicine in the world for pain relief. ③He noted that a dish in which he was trying to grow bacteria for an experiment looked abnormal. ④Another drug that has helped increase the standard of people's health is penicillin. ⑤Many people has fallen ill because of the cold weather. ⑥It turned out that my judgement was right. ⑦It seems as if he has lost interest in his new job again. ⑧Please keep silent at the meeting unless you're allowed to talk. 后自主感悟 1.以上各句中的黑体词均为系动词。系动词本身有一定词义，但是不能单独作谓语。其中例句④的be是最常用的系动词。 2.例句③中的look为“感觉感知”类系动词。 3.例句⑧中的keep为“状态持续”类系动词，而例句①中的prove、例句⑥中的turn out和例句⑦中的seem为“主观判断”类系动词。 4.例句②中的become和例句⑤中的fall为“状态变化”类系动词。 系动词本身有词义，但不能单独作谓语，它后面必须带有表语(如名词、形容词、副词、介词短语、不定式、动名词、过去分词或从句等)形成“系表结构”。
一、系动词的种类 1．“状态持续”类系动词

4．有些系动词如seem，appear，prove可以和to be连用，to be常被省略。 She appeared (to be) happy at the news. 听到这个消息她好像很高兴。 The rumour proved (to be) false. 这个传闻原来是假的。
