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 associated to the big problem of global-warming.

Strategy 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.
Strategy 2: Turn off your computer
When in standby mode, your PC is still using energy.
Turning off a monitor for 40 hours a week may only save $ 5 a month, but it reduces CO2 by 750 pounds.
Strategy 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.
You're reducing pollution. The amount of oil it would take to make just 14 plastic bags would run your car for one mile.
Strategy 4: Use recycled paper in the bathroom
Most of the toilet paper we use is made from  trees found in forests previously untouched by humans.
If every household replaced one roll of toilet paper with a recycled one,424,000trees would still be standing. Look for eco paper towels too.
 Strategy 5: Buy energy-efficient appliances(電器)
Replace the old fridge with an Energy Star appliance and you'll use 15 percent less energy. It might be a little expensive to buy, but  you'll save money on your electricity bills and help the environment.
If we all used one Energy Star appliance at home, it would be like planting 1.7 million acres of new trees.
Strategy 6: 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】What is the best title for the passage?
A．Strategies to Save Money
B．Ways to be Earth-Friendly
C．Strategies to End Global-Warming
D．Ways to Limit Carbon Dioxide
【小題2】According to the writer, what will happen if our PC is switched off when not 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.
【小題3】Which strategies suggest recycling or reuse of things?
A．Strategies 1 & 3.B．Strategies 2 & 5.
C．Strategies 3 & 6.D．Strategies 4 & 5.
【小題4】What benefits do these strategies have in common?
A．They all help reduce the use of energy like electricity.
B．They all cut down the amount of the use of paper.
C．They all result in producing less greenhouse gases.
D．They all aid to preserve our trees and forest.

Besides calling 911, here is what to do in some life-threatening emergencies when no one is around to help.
Lost in the wilderness
First, you’ve got to acknowledge you're in trouble. Stay where you can be seen, clearly and remember to rest. Keeping a sense of humor helps too -- it reduces strum and helps creative thinking. In a wide open area, make a colorful cress out of rocks to show your present position.
Choking
Aim to hit the top of the chair against your stomach, in the soft part below the bony upside-down V of the ribs (肋骨). Make a sudden push against the chair. If you still can’t breathe after six tries, call 911, even if you can’t talk. Write the word “choking” somewhere nearby, and leave the line open until help arrives.
Severe bleeding
Use your hand or clean cotton, or paper towels, or a scarf, or any cloth you can find, and push down on the wound until the bleeding stops. But if you put a band around your leg tightly, you’re going to close the vessels (血管) to the entire leg. In this way, you could loose foot.
Bear attack
If yon surprise a bear, don't run away. That invites an attack. Instead, stand up and back away slowly, without looking the bear in the eyes. If it does charge (猛沖) at you, stick out your chest, raise your arms, and spread your legs. Shout at the bear, to frighten it. If it's going to attack, lie facedown, with your hands held firmly behind your neck. Play dead until you're sure the bear is gone.
1. When you see a colorful cross made of rocks in the wilderness, you know ______.
A. someone is bleeding                  B. someone is choking
C. someone is lost                      D. someone is attacked by a bear
2. If you are still choking after six tries, you should ______.
A. keep a sense of humor                 B. call 911 and leave the line open
C. use your hand our clean cotton         D. lie down with your hands behind your neck
3. Don't tie around your bleeding leg tightly, or you could ______.
A. stop bleeding  B. reduce stress   C. loose your foot      D. cause breathlessness
4. The passage is mainly teaching us how to ______.
A. survive the emergencies                      B. avoid a bear attack.  
C. deal with a choke                         D. find our way

Ted doesn’t like cars. He wants people to stop driving because cars make the air dirty. Ted had an idea. He said,“I’m going to cycle around North America. I want to show everyone that cycling is a fun way to get around. If more people ride bikes, the air will be cleaner.”
He left his hometown with $160 in his pocket. When he got to San Diego, he met another cyclist. The cyclist invited Ted to speak at a big meeting about the environment. He said,“We’ll pay your airfare to Texas and we’ll pay you to talk about your cycling trip.”Two hours later, Ted was on a plane to the environmental conference and to a big surprise!
While he was at the conference, he met Deanna. It was love at first sight! They talked for six hours straight.

“It was difficult at first,”said Deanna. “Ted got up every morning at 6:00 a.m., but I wanted to sleep until noon.”After a few days, they started having fun.

On their way back to Vancouver, they stopped in Edmonton to visit Ted’s relatives. During the stopover, they got married. People tied a “Just Married”sign and tin cans to the backs of their bikes.

科目：高中英語 來源：2014屆黑龍江哈爾濱第四中學(xué)高三上期第二次月考英語卷（解析版） 題型：閱讀理解

Collecting information about pre-employment and filling out an application form are closely connected, However, filling out an application form is much easier because you have total control and have enough time to think and plan.

　　That you are given a form to fill out does not necessarily mean that you have to answer all the questions in it. If the form contains unclear questions or terms and conditions, you can make some changes before signing(簽約)it, or refuse to answer some of the questions. What you must realize is that those terms and conditions have been written by highly paid lawyers. Each word is important, or it would not be there; and you can be sure that there is not anything there that is written with your interests in mind.

　　I know what I speak of because, as a lawyer for Litton Industries. I wrote the terms and conditions that were printed on the back of order forms, I wrote the most tiring terms and conditions anyone has ever seen. Still, 90 percent of the buyers would just sign on them without questioning anything. If anyone questioned them, we would reach an agreement on something that was acceptable to both sides.

　　So when you see a preprinted application that contains questions or terms and conditions, read it all and read it slowly. If you don’t like something, you can simply change the parts you don’t like, Remember that everything can be settled by discussion. To what degree it can be settled depends on your position, of course, and that is something only you can determine.

1.Filling out application forms is much “easier” because_______.

A. everything connected with application forms is easier

B. you can control the form filling with enough time

C. you can plan and have control of the needed time

D. it is easier to collect information about pre-employment

2.We can learn from the underlined part “Each word is important” that _______.

A. questions in a form must be answered

B. everything in a form must be read carefully

C. the conditions that interest you are changeable

D. something of your interests is most important

3.It can be inferred from the 4th paragraph that_______.

A. you must change a preprinted application before it is discussed

B. questions in a form are more important

C. you have little right to determine the conditions you like most

D. it depends on yourself to settle things in a form
