Cooperation(合作研学) 14 The story of Xi Wang At four months old, she outside for the first time. When she was six months old, she bamboo. When she was 20 months old, she herself. 动词不定式: ‘to’ -infinitives Verbs + started to go began to eat learnt to look after Cooperation(合作研学) agree to do sth. 同意做某事 begin/start to do sth. 开始做某事 decide to do sth. 决定做某事 fail to do sth. 做某事失败 forget to do sth. 忘记做某事 hope to do sth. 希望做某事 1.在英语中某些及物动词后接动词 不定式作宾语, 常用的此类动词有: Cooperation(合作研学) learn to do sth. 学着做某事 plan to do sth. 计划做某事 prepare to do sth. 准备做某事 remember to do sth. 记得做某事 try to do sth. 尝试做某事 want to do sth. 想要做某事 Cooperation(合作研学) More verbs + to do (作宾语): need wish promise seem choose refuse like/dislike love stop would like can't wait try one's best Cooperation(合作研学) 注意: 动词不定式的否定形式是“not to + 动词原形”。如: You must promise not to be late again. 你必须保证不再迟到了。 Cooperation(合作研学) More about wild animals (P62) Dad: Do you know anything special about wild animals? Amy: Yes, Dad. For example, dolphins are clever. They can (1) (learn, work out) easy maths problems. Dad: What do you know about bats?

The teacher is coming. stop to have Stop talking 1. 当我们猜测某件事发生的可能性时,常 用may来表示“也许”、“可能”。 2.当句子中已经有谓语动词,而我们又要表达不止一个动作的概念时,其余的动词可以用非谓语形式表达。动词不定式是动词的一种非谓语形式,其基本形式是“to+动词原形”,否定形式是“not to+动词原形”。无人称、数和时态的变化。 summary Summary(归纳拓学) 1. — Don’t forget _ your homework, John. — Ok, I’ll do it right now.
