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 (湿室效应).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 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.
B. Walking to school.
C. Driving a car.
D. Watching TV.

The Internet, mobile phones and Ipads are part of our lives now. Technology is greatly affecting all ways of our lives, from the ways we work to the ways we play. And it even causes a number of social problems such as cloning humans.
We have had lots of technology and it has changed our lives a lot. There is no doubt that humans will continue to use more and more technology. Here are some examples of modern technology that will change our ideas and will affect our lives greatly.
Global positioning system (GPS) (全球定位系统)
It’s a system that uses radio signals from satellites to show exact(精确地) information. It tells you where the user is on the earth in all weather conditions. It’s made up of three parts: satellites, control equipments (设备) on land and receivers.
Space Technology
Russian and American scientists have worked together for the international Space Station (ISS) for a long time. They hope the ISS will provide a long-lasting lab. Such a lab will bring humans limitless(无限的) advantages. It’s even hoped that one day space technology will take humans to their new houses in space.
Underwater Robot
Hercules is a kind of underwater robot with some high technology equipments. It will be used to search for ancient ships which were destroyed into the deep sea during their journey long ago.
The world is changing so quickly that it’s hard for us to catch up with all the new inventions because they seem to come out every month. It’s important for us to learn about new technology and the role that it plays in our lives. So we should be willing to accept modern technology, or we will fall behind the times.
