阅读下面的短文,从每题所给的A、B、C、D四个选项中选出最佳选项。
A
Want to have some tasty ice cream? Try making it by yourself at home. It is much easier than you may think. Just "shake" your way to it!
Ingredients:
2 small plastic bags, 1 big plastic bag, ice, a towel(毛巾), salt, milk, sugar, cream
Steps:
1. Put the cream, milk and sugar in one small plastic bag. Seal(密封) it to keep air out.
2. Put this bag inside the other small bag. Seal it again. Using two bags can keep the mix from spilling(溢出) on other things.
3. Put the two-bagged mix into the big bag. Add the ice and the salt to the big bag. Seal it well.
4. Hold the bag with a towel. Shake and rub the bag. Keep doing this for 5 to 8 minutes. Then, open the bags and enjoy your ice cream.
Science behind shaking:
Milk has fat, protein and water. If you put the mix in the fridge, the water turns into large chunks(块) of ice. This makes it hard to get creamy ice cream. But when you shake and rub the mix, water can stay inside the milk and mix well with the other things.
(
A. Ice cream.
B. The salt.
C. A towel.
D. The water.
(
A. To help the water turn into ice.
B. To make the mix have more water.
