3、牛奶包装的大小

在描述牛奶大小时，除了big和small，我们加上表示容积的单位，就更加清楚喽：

- Do you have anything smaller, like a small carton?
- 有更小点的吗？一小盒的那种？

If you go to an American grocery store, you'll notice that there are a ton of different sizes of milk to choose from.
如果去美国的超市，你会发现牛奶种类多到挑花眼。

Milk is sold in gallons, 1/2 gallons, quarts, and cartons.
牛奶有加仑，1/2加仑，夸脱和盒。

Gallon
加仑

The largest amount of milk you can buy is a gallon jug.
能买到最大瓶的牛奶是一加仑的大桶。

The whole amount of a jug of milk is 128 ounces! This is about 4 litres. Buying a gallon of milk is best if you have a bunch of people drinking it.
一加仑的大桶有128盎司，大概有4升（8斤）。如果喝的人多的话一加仑是最划算的。

1/2 gallon
1/2加仑

That's right! You guessed it! A half gallon of milk has 64 ounces or 2 litres of milk in it.
没错，猜对了，1/2加仑的牛奶有64盎司，大概2升（4斤）。

This size is best for maybe one or two people.
大概一到两个人喝最好。

Quart/Litre
夸脱/升

A quart of milk equals a quarter of a gallon. So, with this in mind, a quart of milk would be 1/4th the size of a gallon, so 32 ounces! This is also about the same size as a litre of milk or 2 斤。
一夸脱牛奶=1/4加仑。32盎司！跟1升或2斤牛奶差不多大。

Carton
盒

There are also cartons of milk. This basically means that the milk is in a paper box or cardboard.
售卖的也有盒装的牛奶。基本上是说牛奶装在一个硬纸盒。

Cartons of milk can come in a lot of different sizes, but usually it's for smaller amounts of milk.
盒装的牛奶也有不一样的尺寸，但通常都是比较少量的牛奶。

For example, cartons of milk can come in quarts (which 1 L), half of a quart (which is 500 mL), and 1/4th of a quart (which is 250 mL).
比如盒装牛奶有1夸脱的（1升），半夸脱（500毫升）和1/4夸脱（250毫升）

The smallest carton size comes in 4 ounces, or about 1/10th of a litre. This is the best if you just want to drink milk with one meal.
最小的盒装牛奶是4盎司的，大概是100毫升。如果你只是吃饭时想喝的话最合适了。

I heard even in England they are using the metric system with litres and kilograms. We are probably the last country who is using the imperial system with quarts and gallons.
我听在英国都用升和公斤这种公制单位。美国可能是仅剩的使用加仑夸脱这种英制单位的人了。
