Even if you are a good high-jumper, you can jump only about seven feet off the ground. You cannot jump any higher because the earth pulls you hard. The pull of the earth is called gravity.

You can easily find out the pull of the earth. If you weigh yourself, you will know how much gravity is pulling you.

Since there is gravity, water runs down hill. When you throw a ball into the air, it falls back down. Because of gravity, you do not fall off the earth as it whirls (旋转) around.

Then, can we get away from the earth and go far out into space? Now you can do it, because spaceships have been invented. Then spaceship will go so fast that it can escape (逃出) the earth’s gravity and carry you into space.

1.In this passage, the word “gravity” means.

A. the pull of everything.

B. the force of attraction(吸引) among objects.

C. the force which attracts objects towards the centre of the earth

D. the force which attracts the earth towards the sun.

2. When you slip(滑) you always fall to the ground because

A. the earth always turns round.

B. the earth has gravity

C. the earth’s gravity is greater than your weight.

D. you are careless.

3. Gravity is strong that

A. it can throw a ball into the air.

B. it makes you jump only seven feet.

C. it can let you fly away from the earth.

D. it can keep everything on earth.

4. Because of gravity,

A. water flows everything.

B. we can go everywhere by ship.

C. water always flows downwards.

D. fish can live in water.

You can be proud of yourselves, even if you can only make one or two of these green changes. The goal here is to limit carbon dioxide and other greenhouse gases, which are closely connected to the big problem of global-warming (全球变暖).

WAY 1: Bring your own cup to Starbucks. You’ll get a 10-cent discount, and it’s one less paper cup to end up in a dustbin. The store won’t create more waste when they throw away a cup.

WAY 2: Turn off your computer. When in standby mode, your PC is still using energy. Turning off a monitor (显示器) for 40 hours a week may only save $ 5 a month, but it reduces CO2 by 750 pounds.

WAY 3: Reuse plastic bags. Instead of throwing away 100 billion plastic bags a year, try and get a second, third, or tenth use out of them. Better yet, next time you shop, try a reusable bag. The amount of oil it would take to make just 14 plastic bags would run your car for one mile.

WAY 4: Use recycled paper in the bathroom. Most of the toilet paper we use is made from trees found in forests. If every family replaced(替换)one roll of toilet paper with a recycled one, 424,000 trees would still be standing.

WAY 5: Plant a tree. Adding green to your garden is beautiful and earth-pleasing. Just one tree will help make cleaner air and save the environment from 5, 000 pounds of hot carbon dioxide each year.

1.How many ways are mentioned(提及) in the passage?

A. Two.            B. Three.                C. Four.                D. Five.

2.What will happen if our PC is turned off when it isn’t in use?

A. It will help to save a large amount of money.

B. It will help to reduce a great deal of CO₂.

C. It will save the amount of oil that runs your car for a mile.

D. It will be like planting 1.7 million acres of new trees.

3.Which ways suggest recycling or reusing of things?

A. Ways 3 & 4.         B. Ways 2 & 3.

C. Ways 3 & 5.       D. Ways 2 & 4.

4.How do these ways do good to our environment?

A. They all help reduce the use of energy like electricity.

B. They all cut down the number of the use of paper.

C. They all produce less greenhouse gases as a result.

D. They all help protect our trees and forests.

5.What is the best title for the passage?

C. Ways to End Global-Warming                 D. Ways to Limit Carbon Dioxide

Growing mushrooms(蘑菇) is probably the easiest thing you can do even if you are new to mushroom growing. It is becoming more common because restaurants are starting to create more dishes that include mushrooms.
