The Earth has warmed by about half a degree(0.50℃)over the last 100 years.It could be getting warmer on its own,but many scientists think that people are making the Earth warmer by making a greenhouse effect(温室效应).The greenhouse effect is important. Without it,the Earth would not be warm enough for us to live on.But just a little warmer than it is now could cause(引起)problems for humans,plants and animals.
Many of the things we do every day can change the Earth’s temperature by sending greenhouse gases(废气) into the air.We send greenhouse gases into the air When we watch TV,turn on lights,dry hair,play video games,wash or dry our clothes or drive cars.The rubbish(waste) from factories and homes also produces greenhouse gases.
Even a small change in temperature can affect ( 影响) our weather.This can cause changes in the sea levels,the air,flooding,and our fresh water.
The change in the temperature can also cause changes in the living places for animals and plants,endangering many animals.
Global warming(全球变暖) is a big problem,and every little bit we do can help.We can save electricity.We can save energy in other ways such as by taking buses or walking rather than driving cars.We can recycle to reduce the rubbish and save natural resources such as trees,oil and metals.We can buy products that don't do bad to the environment and we can turn to solar energy.Remember the little bit that you do will bring a better world.
1.Which of the following does not send greenhouse gases into the air?

Have you ever wondered?
1. Why do airplanes take longer to fly west than east?
It can take five hours to go west-east from New York (NY) to London but seven hours to travel east-west from London to NY. The reason for the difference is an atmospheric phenomenon known as the jet (喷射) stream. The jet stream is a very high altitude wind which always blows from the west to the east across the Atlantic. The planes moving at a constant air speed thus go faster in the west-east direction when they are moving with the wind than in the opposite direction.
2. What would happen if the gravity on Earth was suddenly turned off?
Supposing we could magically turn off gravity. Would buildings and other structures (建筑物) float away? What happened would depend on how strongly the things were attached to the Earth. The Earth is moving at quite a speed, moving at over a thousand miles per hour. If you turn something around your head on a string (细绳), it goes around in a circle until you let go of the string. Then it flies off in a straight line. ‘Switching off’ gravity would be like letting go of the string. Things not attached to the Earth would fly off in a straight line. People in buildings would suddenly shoot upwards at a great speed until they hit the ceiling. Most things outside would fly off into space.
【小题1】What information can we get from the first passage?
A.It is the jet stream that affects how fast airplanes fly. |
B.Planes go slower when they are moving with the wind. |
C.It takes more time to fly from NY to London than from London to NY. |
D.The jet stream always blows from the east to the west across the Atlantic. |

C.come out | D.grow quickly |
A.buildings and other structures would float away |
B.trees and buildings would not so easily fly off |
C.something around your head would not float away |
D.everything outside buildings would fly off into space |
A.It takes seven hours to travel from London to New York. |
B.The earth is moving at a high speed |
C.Everything on the earth will float away if there’s no gravity. |
D.Everything not attached to the earth would fly off in a straight line. |
A.In a research paper. |
