Next, put the bananas in the blender.
Then, pour the milk into the blender.
Finally, turn on the blender.
How many bananas do we need？
We need three bananas.
How much yogurt do we need？
We need one cup of yogurt.
1. How many bananas do we need？
我們需要多少香蕉？
How many 是疑問詞，表示“多少”，后面需跟復數名詞。
詢問多少人或物的句型是：
How many +復數名詞 + 一般疑問句？
如: How many women can you see?
你能看到多少位女士?
How many classes are there in your school?
你們學校有多少個教學班?
How many chairs are there on the floor?
地上有多少椅子?
2. How much 對不可數名詞進行提問，表示“多少”，后面跟不可數名詞。如：
— How much milk do we want?
我們要多少牛奶?
— We need one bottle of milk．
我們需要一瓶牛奶。
How much butter does the cook want？
廚師想要多少黃油？
How much money are there in the purple？
紫色的有多少錢？
注意: money 是不可數名詞。
3. 英語中量的表達方法分為三種類型：
① 表示容器的名詞 + of
a cup of tea, three bottles of milk
② 表示單位的名詞 + of
a piece of paper seven piles of rice (七堆米)
③ 其他詞 + of
some of the apples
4. 可數名詞有單數和復數兩種形式，如：bananas, tomatoes
不可數名詞沒有單、復數形式；
可數名詞單數前面可用不定冠詞a (an)；
不可數名詞前不能有a (an)；
可數名詞復數可用 a few, many 等修飾；
不可數名詞則用 a little, much 等修飾。
詢問可數名詞的“多少”用how many
詢問不可數名詞的“多少”用 how much
英語中個體名詞是可數名詞，它們所表示的人或物可以用數來計數。如：banana, apple, blender, watermelon …
物質名詞一般是不可數名詞，它們所表示的事物不能用數來計數。如：milk, yogurt, honey…
祈使句的用法
本單元的語法重點是祈使句的使用。
祈使句用來表示請求、命令等，沒有主語，動詞用原形。否定的祈使句要在動詞前加 don’t 構成。例如：
Peel the apple, please. 請削掉蘋果皮。
Don’t wake me up tomorrow morning.
明天早上不要吵醒我。
2. 有時候吩咐別人做的某件事要分步驟來完成，并且有一個先后順序，這時候可以適當地使用 first, next, then 和finally，既能使說話人喘口氣，又能使聽話者感到句子的連貫性。
First...（首先……）, next...（接下來……），
then...（然后……）, finally...（最后……）.
Summary
1、用祈使句表達說話者的要求:
Peel the bananas.
Pour the milk in the blender.
2、用 “first, next, then…”等來表達順序:
First, cut up the bananas; then…; next…; last…
3、用“how many,how much”對名詞數量提問
How much milk do we want?
How many chairs are there on the floor?
