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 (全球變暖).
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 (顯示器) for 40 hours a week may only save $ 5 a month, but it reduces CO₂by 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(替換)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.
小題1:How many ways are mentioned(提及) in the passage?

A．Two.	B．Three.
C．Four.	D．Five.

小題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 CO?.

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.

小題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.

小題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.

小題5:What is the best title for the passage?

A．Ways toSave Money	B．Waysto Be Earth-Friendly
C．Ways to End Global-Warming	D．Waysto Limit Carbon Dioxide

小題1:D
小題2:B
小題3:A
小題4:C
小題5:C

Paul Nicklen waited patiently on a sheet of ice in the Arctic. He was there to take pictures for National Geographic. Finally, he saw something big and white. It was a polar bear, swimming towards him in the icy water.

When disaster (災難) happens, you might find yourself without water, gas and electricity. You might even need to leave your home right away. So you are supposed to plan for the bad situations before the disaster comes. Here are some suggestions：
First, have a family meeting. Plan a way to get your family members together if they can't find each other after the disaster. Choose two places for everyone to go to if it isn't safe to return home. The first should be near your house. You can go there in an emergency(緊急情況) like a fire. The second meeting place should be outside your neighborhood.
Next, choose a person outside your area who can help your family get in touch with each other. After a disaster, it is often easier to communicate over a long-distance call than a local one. The person can pass messages between your family members.
Then, get a family disaster kit ready. It should include things your family needs. It can help you survive (生存) at least for three days like bread, water, medicine and things like that. Put them in a bag so you can carry it if you leave in a hurry. When doing it, remember that different people have different needs. Include special things necessary for elderly or young members of your family.
