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：

Listen to part of a lecture in a meteorology class.

Now, Earth’s atmosphere is sort of like a giant weather machine, right?
Uh...with air and water being its key component, a machine powered by energy from the Sun.
So we need to consider the role that air, or more specifically, wind, plays in this machine, so wind is really nothing more than moving air, right?
Now, as air is heated and becomes warmer, it expands, becomes less dense.
When air in a particular area is heated, you get a concentration of warm air in an area of low pressure.
Likewise, when you get a concentration of cold air, that air’s gonna be very dense, so it’s gonna create an area of high pressure.
If you have an area of high pressure next to an area of low pressure, the colder, high pressure air will start moving toward the area of low pressure. Right?
And the warmer air will move away, rising above the cooler air. Okay? Uh...yes. Linda?
So wind is actually generated by the Sun?
Well, Earth’s rotation plays a role, and there are other factors and we’ll come back to all that.
请听气象学课上的部分内容。
地球的大气层有点像一个巨大的气象仪器，对吗？
一个以空气和水为关键成分，靠太阳能提供动力的机器。
所以我们要考虑空气的作用，或者更具体地来说，风在这台机器中所起的作用，风只是运动着的空气而已，对吧？
空气受热，温度升高时会膨胀，密度变得更小一些。
一个具体区域的空气受热时，暖空气就会集中在一个低压区域。
同样的，当冷空气汇集时，那片空气的密度就会变得很大，所以就会创造出一片高压区域。。
如果在一个低压区域旁边有一个高压区域，空气越冷，越多的高压空气就会开始朝着低压区域移动，对吧？
而暖空气便会离开，上升到冷空气之上。Linda，请说？
所以风实际上是由太阳产生的咯？
地球的循环也起了作用，而且还有其他因素，我们稍后都会讲的。


2. 阅读包答案：

虽然我们习惯于将1927年以前的电影叫做“无声电影”，但是就“无声’’这个词的完整意义上说，电影从未真正的无声过.
