先科普一下:太阳系有八大行星
Our planet, the Earth is the third planet from the Sun.
(Earth是专有名词,所以首字母要大写)
It’s a beautiful, rotating sphere.
(rotating作形容词,只限定于放在某个名词前,表示旋转的物体。)
The side facing the Sun is in daylight.
(facing the Sun用来修饰前面的名词side, 后置定语)(in daylight:在白天)
The side facing away from the Sun is in darkness.
(indarkness:在黑夜)
For example, when it’s daytime in the US, it's nighttime in China.
In fact, there's a 12-hour time difference between Boston and Shanghai.
(in fact:事实上,用于陈述观点或客事实)
When it’s midnight in Shanghai, it’s noon in Boston.
我们的星球,地球是离太阳第三远的星球。它是一个美丽的旋转的球体。面朝太阳的一面在白天。背对太阳的一面在黑暗中。例如,在美国是白天,在中国是晚上。事实上,波士顿和上海之间有12个小时的时差。上海是午夜,波士顿是正午。
The earth rotates from west to east. (rotate:【v.】旋转)
To know which direction is east or west, watch the Sun.
The Sun travels through the sky from east to west.(travel through:经过)
The Sun comes up in the east and goes down in the west. (come up:升起,go down:落下)
Again, this is because the earth rotates.
It takes 24 hours for the earth to make a complete rotation.
(it takes+一段时间:做……事情需要多少时间)(rotation[n.]旋转)
And that is the length of one day.
地球从西向东旋转。要知道哪个方向是东,哪个方向是西,就看太阳。太阳从东到西穿过天空。太阳从东方升起,从西方落下。同样,这是因为地球在自转。地球自转一周需要24小时。这是一天的长度。
Because of the earth’s rotation, the Earth is divided into time zones.
(be devided into:被分成)------被动语态:主语是动作的承受者,结构是:be+动词过去分词
Some countries, such as the US, have several time zones. (time zone:时区)(such as:例如)
When it’s 10:00 am in New York, it’s 7:00 am in San Francisco.
Europe and the US are separated by several time zones.(be separated by:被……分离)
When it’s 5:00 pm in Paris, it’s 11:00 am in Boston.
So there is a 6-hour difference between Paris and Boston.
One large country, China, has just one time zone for the whole country.
(the whole country整个国家,the whole world:这个世界)
As a result, at the same time, some parts of the country can be dark and other parts can be light.
(as a result:因此)
由于地球的自转,地球被分成了时区。一些国家,如美国,有几个时区。当纽约是早上10点,旧金山是早上7点。欧洲和美国被几个时区分开。巴黎是下午5点,波士顿是上午11点。巴黎和波士顿之间有6个小时的时差。有一个大国,中国,整个国家只有一个时区。因此,在同一时间,这个国家的一些地区可以是黑暗的,而另一些地区可以是光明的。
As you travel around the earth, the time changes.
The time of day depends on your location on the planet.
(depend on:取决于)
When you travel east or west, you may cross several time zones.
For example, if you travel from Beijing to Los Angeles, you cross 8 time zones.
(travel from sp. to sp.:从……到……)
That means, when it’s noon on Sunday in China, it 8 pm on Saturday in Los Angeles.
For travelers, this means it can be very difficult to sleep after a long flight.
The clock may say 8:00 pm, but for your body, it’s noon. (say:说明,指示)
This is called jet lag.(be called:被称为,被叫做)(Jet lag:时差)
当你绕地球旅行时,时间会改变。一天的时间取决于你在地球上的位置。当你向东或向西旅行时,你可能跨越几个时区。例如,如果你从北京到洛杉矶旅行,你要跨越8个时区。这意味着,在中国周日中午的时候,洛杉矶周六晚上8点。对于旅行者来说,这意味着长途飞行后很难入睡。时钟可能是晚上8点,但对你的身体来说,现在是中午。这就是所谓的时差反应。
