There is nothing more important to life than the sun.Without the sun,all living things on the earth will die.

brightest of all the stars.The distance of the sun from the earth is as much as 150 millionKilometers.Most of the stars are thousands of light years away from the earth.
Do you know the light years?Nothing in the world travels faster than the light.It trarels 30000 kilo meter a second.And one light year means the distance that light trarels in oneyear.

The earth is not the only body that travels around
the sun. With it are eight other planets (行星), fellow members of the sun's
family.
Two of them are nearer while the other six are farther from the sun than the
earth is. The farther they are, the longer trips they make around the sun.
People noticed long ago that these traveling bodies moved around in the sky in
fixed paths. It is a force called gravity (重力) that holds them in their paths.
We know that every little bit of matter in the universe (宇宙) pulls upon every
other bit of matter. Because the sun is so large, the pulling between the sun
and the planets must be very great. If it were not for this pulling, the planets
would fly off into space. In the same way there exists a pull between the earth
and the moon, which keeps the moon traveling in its orbit (轨道) around our
planet, the earth. Gravity holds you to the earth's surface, and pulls the ball
you throw into the air back to it. Of course, the ball also pulls on the larger
earth but the earth is so much larger that the pull is not noticed.
Now remember that large bodies bring to bear a greater pull on any body that
contains less material. But each object in the universe, no matter how small,
pulls on all other objects to some degree.

today food travels thousands miles from the farm to the consumers.what is the reason?is it a positive or a negative trend?
in the contemporary world,technology,as a symbol of 21st century,accelerates the progress of our society on varies fronts.thanks to the improvement of transportation,people nowadays have more choice on food,even foreign food.in this essay i will analyze the causes of this trend and give my own perspective to this situation.
first of all,the improvement of transportation makes the long distant transportation come true.as is known to all,the fruits and vegetables get rotted and bad easily.now the air transportation can deliver the food to the destination in several hours.for example,people living in north part of china can enjoy the food produced in the south and even abroad due to the convenient transportation.also people can enjoy anti-seasonal fruits and vegetables.
secondly,there are economic benefits to both the exporting and importing areas.people can make a lot of money and enjoy a more comfortable life through transporting food to a long distance away from the farm.meanwhile,the *** can have more revenue.the *** can use this extra money to improve its people’s living standard.
from what has discussed above,people can get a clear understanding of the causes of this trend.however,many people assert that the long distant transportation is a waste of fuels and human labor.the food transported to a long distant far away from the farm can be more expensive.many people can not afford that.but in my opinion the consumers themselves will decide what to buy.
all in all,from my own perspective,it is a positive trend.people can enjoy a more comfortable life and the *** can have more money to improve its people’s living standard.
