在托福考试中,大多数学生一提到听力,就会感到头痛。听力的过程是对心理和生理的多重破坏,但在听力中,当大多数学生听到这句话时,“listen to a part of lecture in astronomy class“,会进入痛苦的谷底,仿佛每个单词都穿过自己的大脑,但没有留下任何痕迹,但无论是在训练还是前几年,天文学讲座的概率都很高,换句话说,学生应该熟悉相应的专业词汇,也要了解一定的学科知识背景,下面由新航道的沈阳托福培训小编为您解答!
首先,我们从八大行星的核心和太阳开始
太阳是太阳系的中心,是一颗巨大的行星(star),但在托福听力中,经常提到的一个争论点是太阳是中心,也就是日心,还是地球是中心,你可以试着听tpo21的内容
The ancient Greeks believed that what we called the solar system was in fact the entire universe and that the universe was geocentric. Geocentric means Earth-centered. So the geocentric view holds that the Sun, the planets and the stars all revolve around the Earth, which is stationary. Of course we now know that the planets, including Earth, revolve around the Sun, and that the solar system is only a tiny part of the universe.
Solar system 太阳系
Geocentric 以地球为核心
Planet 行星
Revolve 转动
Stationary 固定的;静止的
对于两种理论的争论,托福听力会考虑以下几点
首先,为什么古人对地心如此执着?
其次,古人为了保持日心说的地位做了些什么?
反驳地心说的证据是什么?
最后,对日心说有什么评价?
接下来,
它是八大行星之一,
水星Mercury
水星是离太阳最近的行星。由于这种亲密接触,水星的温度与它的名字相差甚远,而太阳风则远离太阳(solar wind)吹啊吹,这也造成了水星那稀薄的空气,而这稀薄的空气给水星带来的礼物就是大大小小的坑(crater)
Mercury's thin atmosphere consist of trace amounts of hydrogen and helium. The atmospheric pressure is only about 1 x 10-9 millibars; this is a tiny fraction (about 2 trillionths) of the atmospheric pressure on Earth.
Since the atmosphere is so slight, the sky would appear pitch black (except for the sun, stars, and other planets, when visible), even during the day. Also, there is no "greenhouse effect" on Mercury. When the sun sets, the temperature drops very quickly since the atmosphere does not help retain the heat.
Hydrogen 氢气
Helium 氦气
Atmosphere pressure 大气压
Pitch black 漆黑一片
Greenhouse effect 温室效应
它的名字与它的旋转速度有很大关系。希腊罗马神话中的主神宙斯有很多谣言,其中一个很好色。而且怕老婆赫拉,典型的老婆管严,所以每次去世都不是因为真面目。有时候变成公牛,老鹰,有时候公羊。遇到美女,不是直接出来追,而是写情书,一个接一个地传递。玛丽是罗马神话中的信使之王,是神话中跑腿最好的,所以最胜任这份工作。
Mercury was named after Mercury, the mythical Roman winged messenger and escort of dead souls to the underworld. It was named for the speedy Mercury because it is the fastest-moving planet.
Escort 护卫队
Winged 飞行;快速的
Underworld 炼狱
托福对水星的调查相对较少,但这些相关的知识点,我们可以记住自己的脑海哦!
接下来是九大行星中的维纳斯。因为它在这个宇宙中散发出白色的光辉,人们赋予它美神的名字,而这个亚马逊的白色号码实际上是由盐酸云反射太阳光引起的。
Venus is the second planet from the sun in our solar system. It is the hottest planet in our Solar System. This planet is covered with fast-moving sulfuric acid clouds which trap heat from the Sun. Its thick atmosphere is mostly carbon dioxide. Venus has an iron core but only a very weak magnetic field.
Sulfuric acid 盐酸
Thick 厚的
Iron 钢材
Core 核
