Language Focus
1.What did you have for breakfast
你们还记得助动词do和does吗 did是do和does的过去式。第二单元我们学习了行为动词一般过去时的陈述句表达，本单元我们将学习它的疑问句和否定句表达。这都少不了did 帮忙哦!
一般现在时 一般现在时(三人称单数) 一般过去时
否定句 We don't play football every day He doesn't play football every day He didn't play football yesterday
一般疑问句 Do you play football every day Does he play football every day Did he play football yesterday

No,we don't No,he doesn't. No,he didn't.
特殊疑问句 What do you usually do every day What does he usually do every day What did he do yesterday
2.healthy的意思是“健康的”,health(健康)是它的名词，而unhealthy则是指“不健康的”。英语中，形容词前面加上un-常常表示否定或相反。类似的词还有：happy—unhappy,fair--unfair(不公平的)。
3.食物类的名词可分为可数名词和不可数名词，我们可以在前面加a little. a lot of、some 、many 、much等来表示量的多少。a little 只可以修饰不可数名词，它相对应的a few (一点)修饰可数名词复数。a lot of 和some 既可以修饰可数名词复数，也可以修饰不可数名词。
许多 一些 许多 一点儿 示例
a lot of some many a few 可数名词：eggs,carrots,tomatoes,pies,sandwiches,hamburgers,pizzas
much a little 不可数名词：chicken(鸡肉),rice,meat, water,soup,milk,bread,fish (鱼肉)
