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 bestselling 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。
