小组讨论
We often call Switzerland “Green Switzerland”. Do you understand the meaning of “green” here 四人一组讨论。
●In Switzerland, things like glass, plastic and paper are separated into different groups and then recycled. 在瑞士,像玻璃、塑料和纸这样的东西都被分为不同的类别,然后再循环利用。
separate在此处是不及物动词时,意为“分开,隔开”。 例如:
His parents separated when he was very young. 在他很小的时候,他的父母就分开了。
【拓展】separate作不及物动词时,意为“分开,隔开”。separate into“把……分成,分离成”;separate... from... “把……和……分开(离)”。例如:
My mother is separating the good apples from the bad ones. 我妈妈正在把好苹果和坏苹果分开。
【辨析】separate和divide
separate 通常指把构成整体的人物、团体、机构或部件等拆开或分散,或指由于事物的阻隔而彼此分离,常用结构有“separate into”或“separate...from...”
divide 常指把某物分成部分、块或组等,或把某物切割分成若干份,也可用于抽象意义的划分、割裂,常用结构有“divide...into...”,意为“把……分成……”
[做一做]根据所给提示完成下列各题。

is separated
● Otherwise, we will be punished. 否则,我们将会被惩罚。
punish在此处是及物动词,意为“处罚,惩罚”,后接名词或代词作宾语,常用于被动语态中。例如:
If you cut down a tree, you’ll be punished and will have to plant another tree in its place. 如果你砍倒一棵树,你会受到处罚，而且你得在原地再种一棵树。
【拓展】be punished for “因……受罚”;be punished with “用……来处罚”。例如:
He was punished for speeding. 他因超速驾车而被罚。
【注意】punish的基本意思是“罚,处罚”,指因违背法律、违抗权威或做错事而对其强制惩罚，引申义为“粗暴地对待,痛打”。
