1.听写包 答案：

Now, there are other ways we can describe mixtures, and one of these is by properties, uh, variable properties.

A real simple example of this is the taste and color of a cup of coffee.
The more coffee that’s dissolved in the water, the stronger the taste of the coffee, and the darker the color, the darker the solution.
So, color and taste, these are two variable properties.
And these variable properties, they vary of course, because of the relative amounts of the components, and the melting or freezing points of liquids too.
A solution of salt water, for example, will have a different freezing point depending on how much salt is dissolved in the water.
我们还有其他方式描述这些混合物，其中之一就是通过性能，变性质。
一个很简单的例子就是一杯咖啡的味道和颜色。
溶解在水中的咖啡越多，咖啡的味道就越强烈，颜色也就越深，
所以，颜色和味道，这是两种变性。
而这些变性质，它们当然是不同的，因为这些成分的相关数量不同，还有液体的融点和冻点也不一样。
比如一个盐水的溶解物会有不同的冻点，这取决于水中溶解了多少盐。

2.阅读包答案：

这个例子有效地说明，不管我们面临何种挑战，我们绝不应该夸大困难，低估自己的能力。

3.写作包答案：

A Chinese new law stipulates that adults must regularly visit and take care of their parents. If they don't do so,they break the law.The new law, however, has given rise to a public debate on whether it is feasible.Many people doubt whether the law is enforceable, because it does not clarify how often people have to visit their parents.In addition, working people who live far away from their parents will find it difficult to take leave to go home regularly.Some scholars have praised the law,though, because it is aimed at arousing people's awareness of loving the elderly and reminding them to always keep their obligations in mind.
