【合作探究】

1.DO you have anything valuable in your schoolbag?翻译此句子

___________________________________________________________

注:anything valuable一些贵重的东西。形容词修饰不定代词anything, nothing, something等时,形容词要后置。

[拓展]-able是形容词后缀,加在原来的单词后面,表示---的;能---的;具有---的性质。类似的有:comfortable 舒服的countable可数的 allowable 允许的believable可信任的

2.Somebody must have picked it up. I’ll call them now to check if anybody has it. 翻译此句子 ______________________________________________

注:pick up捡起,捡到。它为动副型短语,当名词作其宾语时放在pickup之间或up之后均可;但代词作其宾语时只能放在pickup之间。即代中名后。

【拓展】pick sb up接某人。I’ll pick you at the airport.我会去机场接你。

3. the rest of 其余的,剩余的(P582d

“the rest of+名词作主语时,谓语动词的单复数取决于of后的名词的单复数形式。
