When you watch TV and play video games you make global(全球的) warming worse! It may seem hard to believe, but when electricity is made, so are greenhouse gases(温室气体). This means that every time you use electricity you help make global warming worse!
Cars are also making global warming worse. They burn fossil fuels(化石燃料) in their engines, and send lots of greenhouse gases into the air.
Global warming may be a big problem, but we can all help stop it. People can try to drive their cars less. Or even get ones that run on sunlight! You can also help. Let’s try one of these top ideas:
(1) Try to use less electricity. Turn off lights, your television, and your computer when you’ve stopped using them. To make electricity, fossil fuels are burned in big factories. But burning fossil fuels also makes greenhouse gases. You should also try to watch less TV.
(2) Plant trees. Not only is it a fun thing to do, but it is also a great way to lower the number of greenhouse gases in the air. Trees take carbon dioxide out of the air when they grow.
(3) Don’t throw away your rubbish, try to recycle it. If rubbish is not recycled, it is put in the ground. There it rots(腐烂) and makes a greenhouse gas called methane(甲烷).So try to recycle cans, bottles, plastic bags and newspapers. It’ll make you feel great! And it’ll help the Earth.
1.If we _____, we may make global warming worse.
A. use less electricity B. drive a car on sunlight
C. plant trees D. throw away rubbish
2. ______ will make global warming worse.
A. Methane B. Cans C. Newspapers D. Bottles
3.Using less electricity does good to global warming because_______.
A. the less electricity is used, the more greenhouse gases are produced
B. the more electricity is used, the more greenhouse gases are produced
C. more electricity is used, less greenhouse gases are produced
D. less electricity is used, more greenhouse gases are produced
4.Which is the following is NOT TRUE according to the passage?
A. Driving cars on sunlight helps to stop global warming.
B. When cars burn fossil fuels, they produce greenhouse gases.
C. When trees grow, they send carbon dioxide into the air.
D. By planting more trees, we can lower the number of greenhouse gases in the air.
Don’t throw away the waste paper. It needs so that it can be reused.
A．to destroy B．destroying C．to collect D．collecting
A wise man used to go to the ocean to do his writing. He had a habit of walking on the beach every morning.
One day, when he was walking along the shore（海岸）, he saw a young man moving like a
dancer. He smiled to himself at the thought that someone would dance on the beach. So he began to walk faster to catch up.
As he got closer, he saw that the young man wasn’t dancing, but instead he was reaching down to the shore, picking up something and very gently throwing it into the ocean.
He called out, “Good morning! What are you doing?” The young man stopped, looked up and replied, “Throwing starfish in the ocean.” “I guess I should have asked, why are you throwing starfish in the ocean?”
“The sun is up and the tide（潮汐）is going out. And if I don’t throw them in, they’ll die.”
“But, young man, don’t you realize that there are miles and miles of beach and starfish all along it. You can’t possibly make a difference!”
The young man listened politely. Then he bent down, picked another starfish, and threw it into the sea, and said, “It made a difference for that one.”
There is something very special in each and every one of us. We have all been gifted（赋予）
with the ability to make a difference.
We must each find our starfish. And if we throw starfish wisely and well, the world will be better.

D．Helping the young man pick up starfish.
2.Why did the young man throw the starfish into the ocean?
A．To have fun.
B．To study starfish.
C．To feed some fish.
D．To save starfish.
3.What can we learn from the story?
A．Each of us should learn to protect starfish.
B．People living on the shore always try to save starfish.
C．Each of us has the ability to make an important effect on something.
D．People can come up with some good ideas when walking on the shore.
Oriole’s Nest
Picky, Picky
Scientists have no idea exactly why birds choose certain objects to build their nests. But scientists know that the main reason birds build nests is to keep their babies safe, warm and healthy.
Baby birds grow faster and are healthier when they are warm. They also learn to fly and leave the nests sooner than birds without warm homes.
What A Yarn (纱)
Yarn is big on an oriole’s shopping list during nest building. Scientists are still trying to work out why so many birds choose white yarn over other colors for nest building.
Scientists think that the white objects remind birds of cotton fluff (绒毛) they find in the wild.
Do It Naturally
Even though birds can help us recycle some of our junk by using it to build nests, they also need to use lots of natural things. Long grass, dried sticks, spider’s silk and mud are some of the natural ingredients that are good for nests, too.
You can make a collection box of things to leave for birds so they can help themselves. Hang a small plastic box with holes on a tree branch. Fill the box freely with nest building goodies. Hang the box on a tree and watch birds climb on board to pick through the junk to find their treasures.
Warning: Don’t let the birds turn into a tasty treat. Keep your bird station away from places where cats hang out.
For The Birds!
Stop! Don’t throw all that garbage out! Give some to the birds. Look and see how your old junk can help beautify and warm a bird’s new home.
1.The baby birds with warm homes are able to _____.
A. choose right objects B. leave the nests sooner
C. build good nests D. learn to fly higher
2. What can people make for birds to build nests?
A. Holes on the tree. B. Food out of the rubbish.
C. A warning board. D. A collection box of things.
3.What can we learn from the passage?
A. Birds build nests to store things.
B. Birds regard white objects as cotton.
C. Birds and humans can help each other.
D. Birds and cats fight against each other.
