day. The Internet brings the outside world closer to people"s homes. Some people say the world is smaller than
before because of the Internet.
What"s going on in other countries? How do people live in places far away? Is there a good sports game somewhere? What"s the life like in the deepest part of the sea? If you want to answer all these questions just come to
the Internet. Of course people can also learn through reading or listening to the radio. But with the Internet they
can learn better and more easily. A lot of information (信息) can be collected at a great speed.
Can we go shopping without leaving home? Can we see a doctor without going to the hospital? Can we study without going to school? Can we draw money without going to a bank? All these things seemed to be impossible but now they have become quite possible. The Internet helps us open our eyes. The Internet also helps us open
our minds. The Internet often gives us new ideas. In a word it helps us in many ways. Great changes have taken place in our life since the use of the Internet.
B. the Internet makes the earth smaller in size
C. the Internet brings the outside world closer to them

your hands. In the second basin mix hot water with cold water. Fill the third basin with cold water from the

"day" to mean 24 hours. But when we talk about day and night, we are using "day" to mean the time
between sunrise and sunset. Since the earth looks like a ball, the sun can shine on only half of it at a time.
Always one half of the earth is having day and the other half night. A place is moved from day into night
and from night into day over and over by the spinning (旋转)of the earth. At the equator (赤道) day and
night are sometimes the same length. They are each twelve hours long. The sun rises at 6 o"clock in the
morning and sets at 6 o"clock in the evening. For six months the North Pole is tilted (倾斜) toward the sun.
In those months the Northern Hemisphere (半球) gets more hours of sunlight than the Southern
Hemisphere. Days are longer than nights. South of the equator nights are longer than days. For the other
six months the North Pole is tilted away from the sun. Then the Southern Hemisphere gets more sunlight.
Days are longer than nights. North of the equator nights are longer than days. Winter is the season of long
nights. Summer is the season of long days.
B. the pulling
C. the spinning
D. the passing
sit, gravity holds you down. When you lie down, gravity holds you to the bed.
We know gravity is everywhere even though we can"t see it.We know it pulls on every stone and every
drop of water. It pulls on everything.
The gravity of the earth pulls everything towards the center of the earth.You know this when you try to
lift a heavy stone. Gravity pulls it down. The more the stone weights, the more gravity pulls on it. To lift
the stone, you must pull up harder than gravity pulls down.
The earth has gravity and the moon also has gravity. The moon has less gravity than the earth has. This
means the moon"s gravity does not pull as hard as the earth"s gravity.
Do you weigh 60 kilograms? That means the pull of the earth"s gravity on you is 60 kilograms. If you
were on the moon, you would weigh only 10 kilograms. The pull of the moon"s gravity on you would be
only 10 kilograms.
A. 物体质量
B. 物体重量
C. 万有引力
D. 宇宙能量
moon in the night.
The sun is much bigger than the earth, and the earth is bigger than the moon. So the sun is the biggest

The moon is our satellite (卫星). It is also our neighbor. It goes round the earth all the time. The moon
goes at 8 kilometers a second. The moon can"t give out light or heat itself, and nothing can live on it.
