【知识点1】英语数词的构词规律
数字的拼写大部分是有一定规律的。
数字1~12的英文拼写没有什么共同的规律,需要我们记住。

除了13, 15和18, 其余分别是在4, 6, 7, 9的英文单词four, six, seven, nine后面加teen构成, 而13是thirteen, 15是fifteen, 18是eighteen。

【知识点2】How many …?询问对方物品数量的句型
【原文】How many stickers do you have? 你有多少贴纸? (18)
解析:·how many意为“多少”,用于询问可数事物的数量,后接复数名词。

·回答时可直接用基数词回答。
问句句型:How many + 可数名词复数+ do you have?
答语:I have + 基数词+ 可数名词. / 基数词.
典例:—How many rubbers do you have? 你有多少块橡皮?
—Two./I have two rubbers. 两块。
/我有两块橡皮。
注意:how many和how much 都可以用来询问物品的数量,区别如下:
how many + 可数名词的复数
how much + 不可数名词
例:--How much milk(do you want)?(你想要)多少牛奶?
--How many cars do you have? 你有多少量小汽车?
