You can answer the questions like these: A.Yes,we should. B.No,we mustn't. 1.Should we drop litter in the park? 2.Should we drop litter in the library? 3.Should we drop litter in the cinema?
Now look at the picture,and make sentences with the following wdrds.
• You must ... • You mustn't ... drop litter jump shout kick pick paint run play eat talk wash climb sleep fish draw ride bounce
Revision:There be 句型
• There are + 可数名词复数 • There is + 可数名词单数/不可数名词
• 记忆口诀： There be句型有特点，主语跟在be后面。 单数主语用is，复数用are也不难。 多个主语并列时，be随第一主语变。 否定be后加not，疑问be在there前。 介词短语表地点，“有”是“存在”记心间。
