Pair work. Talk and write.
Let’s learn.
Danny, candy isn’t good for your teeth.
丹尼,糖果对你的牙齿不好。
这是表示某物对某人/某物(没)有好处的句型。
be good for意思是“对……有好处”, 其反义词组be bad for 意思是“对……有害处”。主语可以是名词,可以是动名词。其否定句要在be 后加not。
句型结构:主语 + be + (not) good for + 宾语.
Let’s learn.
How about some fruit 买些水果怎么样
how about的意思是“(建议时说)怎么样;好吗”。
后面可以跟名词、代词宾格、动名词等。
句型结构: How about + 其他
如: How about this book 这本书怎么样
How about singing 唱歌怎么样
Let’s learn.
how about = what about 两者都表示“……怎么样”。两者一般没什么区别,只是how about 更倾向于建议。
如: I want some water. What about you 我想来些水。你呢
Let’s learn.
Danny, don’t use that bag.
丹尼,不要使用那个袋子。
这是一个祈使句的否定形式。祈使句表示命令、请求、建议的语气。这里可以翻译为“别……”。我们知道,祈使句通常省略主语you,以动词原形开头。因此它的否定句要借助助动词do 来完成。句型结构: Don’t + 动词原形 + 其他.
如：Don’t run!
Don’t play on the street!
Let’s act.
游戏规则：和爸爸妈妈讨论去买东西的情景。可根据所给句型适当发挥。
如：
A: What do you want to buy
B: I want to buy …
A: How about some …
B: OK, let’s buy some …
