人教版新目標初中英語八年級上冊How do you make a banana milk shake教案2篇
1. First, ... then, ... next, ... finally, ...首先，……然后，……接著，……最后，……這是英語中表達做某事的步驟的一種說法。如果步驟較多，還可以說：first-next-after that-later on-finally/at last通常你會聽到說英語國家的人在說 first, next, then, finally 和后面的內(nèi)容時，他們會做一些停頓。這樣就能提前告訴聽者接下來講的是一系列的步驟。這一點在朗讀和聽力中應特別注意。2. how many, how much均為疑問詞，同是“多少”，但用法不同。請看：how many修飾可數(shù)名詞復數(shù)，how much修飾不可數(shù)名詞。但在用法上，同學們常犯如下錯誤：1) [誤] 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是形容詞，常修飾名詞作定語，故后面跟名詞。2) [誤]How much tea are there on the table?[正]How much tea is there on the table?[析] how much修飾不可數(shù)名詞時，謂語動詞用單數(shù)。how many與how much的區(qū)別可簡記為：前how many：問“多少”，復數(shù)名詞后面跑；how much問“多少”，不可數(shù)名詞單數(shù)好。前者答語用基數(shù)詞，后者答語用數(shù)量關系。
