    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(yīng)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(fù)數(shù),how much修飾不可數(shù)名詞。但在用法上,同學(xué)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(fù)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(guān)系。
