各位同学们，为了督促帮助大家持续提升英语能力，培君老师们特意给大家准备了托福每日一包。每天覆盖听说读写内容，坚持完成两周以上，就能见到自己的英语能力不断上涨哟。

1.听写包 答案：

So the mixture contains only one phase, even though two phases went into it.

It now contains one phase and we can’t detect any boundary between the water and the alcohol once they’re mixed together.
The two portions combined to form a single phase.
Now, if homogeneous mixtures are ones that are the same throughout, then what do you suppose heterogeneous mixtures are?
Right. Mixtures that are different throughout.
If you mix oil and water together, the mixture contains two liquid phases because the oil will float on top of the water because of the oil’s lower density.
They are not going to mix together like alcohol and water do.
You can see the boundary between them and in fact, they are mechanically separable.
The same is true for soil, which is a mixture of solid materials.
So if you look closely at a sample of soil, you are going to see bits of sand, some black matter, maybe even pieces of vegetation.
Since you can see all the different components, detect distinct boundaries, we’ve got multiple phases.
And in fact, you can pick out the components, the various portions can be mechanically separated.
所以这种混合物只包含了一种状态，虽然有两种状态进入了其中。
它现在只包含一种状态，一旦水和酒精混合到了一起，我们就发现不了它们之间的界限了。
这两部分结合起来形成了一个单独的状态。
如果同质混合物是输量相同的混合物，那你们认为异种混合物是什么呢？
没错，输量不同的混合物。
如果你把油和水混合在一起，这种混合物就会包含两种液体状态，因为油会浮在水上面，因为油的密度更低。
它们不会像水和酒精那样混合在一起。
你能看到它们之间的界限，而且事实上，它们在物理上是可以分离的。
这同样也适用于泥土，泥土是固体材料的混合物。
如果你仔细看一个泥土样品的话，会看到一些沙子、一些黑色的物质，也许甚至还能看到几片植物。
既然你能看到所有不同的成分，发现明显的界限，那我们就有了多种状态。
事实上，你可以把里面的成分挑出来，这些不同的部分在物理上是可以分离的。

感谢您花时间阅读我的来信，盼望不久后能见到一些改变。

3.写作包答案：

Being ready to help others is one of the fine traditions of Chinese nation.By helping others，one not only offered help to others,but also expressed one kind of self-respect.To help others,one should give up selfishness and shouldn't consider his own interest all the time.Think more of others and initiatively give a hand to those that need help.To be ready to help others,one should live happily and avoid asking for trouble.When helping others, one can get happiness at the same time and enjoy the pleasure of life.To be ready to help others,one should take action actively instead of just saying it.Be down-to-earth, and offer service to others with passion.Even for the simple things,just start doing them bit by bit.
