Not "How much apples do you want?" — say "How many apples do you want?". 苹果是能数的（one, two, three），所以用 How many。
试一试: ___ students are in the class? (How many / How much) 答案: How many — 学生是能数的（one, two, three），所以用 How many。How much 留给不能数的东西。
How much：不能数的东西
How much 用在不能一个一个数的东西上：water, time, rice。
How much water do you drink?
How much time do we have?
How much rice do we need?
Not "How many water do you drink?" — say "How much water do you drink?". 水没法一个一个数，所以用 How much。
试一试: ___ water do we need for the pot? (How much / How many) 答案: How much — 水没法一个一个数，所以用 How much。How many 是给能数的东西用的，比如几杯水。
容易搞错的那个
Money 是容易搞错的那个。dollar 和 cent 可以数，所以感觉它是可数的，但 money 本身是不能数的，所以用 How much。
How much money do you need for the market?
How much money is in your bag?
Not "How many money do you need?" — say "How much money do you need?". dollar 和 cent 可以数，但 money 本身不能数，所以用 How much。
试一试: Wei: I want to buy the vegetables for the class. Camila: ___ money do you have with you? 选出合适的说法： (How much / How many) 答案: How much — Money 是容易搞错的一个：dollar 可以数，但 money 没法一个一个数，所以用 How much。
much 还是 many？
这两个问法你都已经会了。拿不准用哪个的时候，就试着数一数这个词：one, two, three。Tomatoes 能数，所以用 How many。Bread 不能这样数，所以用 How much。
tomatoes → one, two, three → How many tomatoes?
bread → you cannot count it → How much bread?
money → you cannot count it → How much money?
试一试: Camila: We need onions for the class today. Amina: ___ onions do you want? 选出合适的说法： (How many / How much) 答案: How many — 如果你选了 How much，那是用于不能一个一个数的东西。Onions 可以数，one, two, three，所以这个问题用 How many。
How much is it?
你已经会用 How much is it? 问价钱了。这里 How much 还有第二个用法：后面紧跟一样东西时，问的是数量。
How much is it? → Three dollars.
How much are the tomatoes? → Two dollars.
How much water do you want? → A glass, please.
Not "How much water is it? when you want the price of the water." — say "How much is it? when you want the price.". How much 后面紧跟 is 或 are 时，你问的是价钱。
试一试: Hiroshi: This bag of potatoes looks good. ___ Camila: The tag says four dollars. 选出合适的说法： (How much is it? / How much do you want? / How many are there?) 答案: How much is it? — Camila 读出的是价钱，所以 Hiroshi 问的是价钱，而问价钱时 How much 后面紧跟 is。How much do you want? 问的是数量，How many are there? 问的是个数，这两个的回答都不会是多少 dollars。
a lot of
东西很多的时候，就说 a lot of。能数的和不能数的都能用，所以你不用再选。
There are a lot of tomatoes on the table.
There is a lot of water in the pot.
We have a lot of time before dinner.
试一试: Lars: The crate on the counter is full of fruit today. Camila: Yes, we have ___ apples this week. 选出合适的说法： (a lot / a lot of / much) 答案: a lot of — 放在东西前面时，要保留 of：we have a lot of apples。把 of 丢掉是这里常见的错误，而 much 用于不能一个一个数的东西，所以不跟 apples 搭配。
