  • 人教版新目标初中英语八年级上册How do you make a banana milk shake教案2篇

    1. First, ... then, ... next, ... finally, ...首先,……然后,……接着,……最后,……这是英语中表达做某事的步骤的一种说法。如果步骤较多,还可以说:first-next-after that-later on-finally/at last通常你会听到说英语国家的人在说 first, next, then, finally 和后面的内容时,他们会做一些停顿。这样就能提前告诉听者接下来讲的是一系列的步骤。这一点在朗读和听力中应特别注意。2. how many, how much均为疑问词,同是“多少”,但用法不同。请看:how many修饰可数名词复数,how much修饰不可数名词。但在用法上,同学们常犯如下错误:1) [误] How many are there bananas on the table?[正] How many bananas are there on the table?[析] how many, how much 中的many,much是形容词,常修饰名词作定语,故后面跟名词。2) [误]How much tea are there on the table?[正]How much tea is there on the table?[析] how much修饰不可数名词时,谓语动词用单数。how many与how much的区别可简记为:前how many:问“多少”,复数名词后面跑;how much问“多少”,不可数名词单数好。前者答语用基数词,后者答语用数量关系。
