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 they, like other types of electromagnetic wave, can travel basically anywhere, through a vacuum, or through atmosphere or water.
Now, radio waves can be detected. For example, very low frequency radio waves can be detected with a special type of radio receiver
called a very low frequency radio or VLF radio, which can pick radio waves with very low frequencies, from 3 to 30 kilohertz,
which aren’t really picked up by a regular household or car radio.
So VLF radios pick VLF radio waves and convert them to sounds we can hear.
Um, on Earth, the main source of naturally occurring VLF emission is lightning, which generates a pulse of radio waves every time it flashes. Yes, Laura.
Since you almost always get lightning with thunderstorms. We can pick up VLF waves pretty often, right?
You just have to wait until there is a thunderstorm.
Ah, do you? Have to wait? VLF receivers are very sensitive and VLF waves travel very far.
So you can pick up emission from lightning that’s far away.
所以它们,和其他类型的电磁波一样,基本上可以在任何地方穿梭,可以穿过真空环境或者空气或水。
无线电波是可以探测到的。比如说,很低频次的无线电波可以用一种特别类型的无线电接收器探测到,
这种接收器叫做非常低频次的无线电接收装置或VLF无线电装置,它能接收到很长低频次的无线电波,从3千赫到30千赫,
这个范围内的无线电波不会被寻常家用的或车载无线电装置接收到。
所以VLF无线电装置会接收到VLF无线电波,并且把它们转变成我们能听到的声音。
在地球上,自然释放VLF的主要来源是闪电,它每一次闪现时会产生一个脉冲的无线电波。Laura,请讲。
既然在雷暴中几乎总是会有闪电,那我们可以经常接收到VLF电波,对吗?
你只需要等到有雷暴就行了。
是吗?要等吗?VLF接收器非常敏感,而且VLF电波传播得非常远。
所以你从很远的地方就能接收到闪电释放的电波。
2.阅读包答案:
而且,人类还有能力改变自己的生存环境,从而 让所有其他生命形态服从人类自己独特的想法和想象。
3.写作包答案:
Although ancient Chinese mythology does not have relatively complete plot and mythological figures don't have systematic genealogy, they have distinct features of oriental culture, among which the spirit of esteeming virtue is particularly significant.When compared with Western mythology, especially Greek mythology, this spirit of esteeming virtue is even more prominent.In Western mythology, especially Greek mythology,the criteria for judging whether a god is good or not are mostly the god's wisdom and strength,while in ancient Chinese mythology, the criterion lies in morality. This way of thinking is deeply rooted in Chinese culture.For thousands of years, this spirit of esteeming virtue has affected people's comments on historical figures and expectations of real people.
