2010年6月英语四级全真预测试卷及答案详解(6)

　　This step can be accomplished at home with a rock salt/ice mixture for freezing and a hand or electric cranked dasher to mix and scrape off the ice crystals.

　　Once the ice cream has come out of the ice cream maker, the process isn't finished. At this point, the mixture is frozen, but still soft. Large chunks of candy and other goodies are now added. Then the ice cream is placed into containers. Factory machines pour it straight into cartons or buckets, or it can be extruded(挤压出)into shapes that have wooden sticks placed into them for individual treats.

　　Now the ice cream needs to be reduced to a very low temperature, zero degrees Fahrenheit or below. Factories make it even colder since they need the ice cream to stay frozen while it is packaged and loaded onto trucks. It needs to be very cold to freeze the ice cream quickly and prevent the formation of large ice crystals. This process is known as hardening. "Soft-serve" is often simply ice cream that has not gone through this process.

　　We'll learn about the ice cream industry in the next section.
