We already know the fastest, least expensive way to slow climate change: Use less energy. With a little effort, and not much money, most of us could reduce our energy diets by 25 percent or more—doing the Earth a favor while also helping our wallets.

Not long age. My wife, PJ, and I tried a new diet—not to lose a little weight but to answer an annoying question about climate change. Scientists have reported recently that the world is bending up even faster than predicted only a few years ago, and that the consequences could be severe if we don’t keep reducing emissions（排放）of carbon dioxide（CO₂）and other greenhouse gases that are trapping heat in our atmosphere.

We decided to try an experiment. For one month we recorded our personal emissions of CO₂^. . We wanted to see how much we could cut back, so we went on a strict diet. The average US household（家庭）produces about 150 pounds of CO₂ a day by doing common-place things like turning on air-conditioning or driving cars. That’s more than twice the European average and almost five times the global average, mostly because Americans drive more and have bigger houses. But how much should we try to reduce?

For an answer, I checked with Tim Flannery, author of The Weather Makers: How Man Is Changing the Climate and What It Means for Life on Earth. In his book, he had challenged readers to make deep cuts in personal emissions to keep the world from reaching extremely important tipping points, such as the melting（融化）of the ice sheets in Greenland or West Antarctica. “To stay below that point, we need to reduce CO₂ emissions by 80 percent,” he said.

Good advice, I thought. I’d opened our bedroom windows to let in the wind. We’d gotten so used to keeping our air-conditioning going around the clock. I’d almost forgotten the windows even opened. We should not let this happen again. It’s time for us to change our habits if necessary.

1.Why did the author and his wife try a new diet?

A. To take special kinds of food          B. To respond to climate change.

C. To lose weight                      D. To improve their health

2.The underlined words “tipping points” most probably refer to

A. freezing points       B. burning points       C. melting points     D. boiling points

3.It can be inferred from the passage that

A. it is necessary to keep the air-conditioning on all the time

B. it seems possible for every household to cut emissions of CO₂

C. the average US household produces about 3,000 pounds of CO₂ a month

D. the average European household produces about 1,000 pounds of CO₂ a month

4.Which of the following would be the best title for this passage?

A. Saving Energy Starts at Home

B. Changing Our Habits Begins at Work

C. Changing Climate Sounds Reasonable

D. Reducing Emissions of CO2 Proves Difficult

My sister Jodie and I are always traveling for work. As jewelry designers, we need to go to a lot of shows. We can’t pack lightly and usually bring about four suitcases filled with our work.

Most of our stuff is made from heavy materials and metals. So part of the routine for us when we fly is getting stopped by security. Our jewelry sets off the alarms, and we’ve become accustomed to arriving early to go through private screenings. Most of the time, it’s not troublesome.

However, on our recent trip to a Paris trade show, we were stopped at security and asked to empty our bags. One of the agents walked over to another agent and they started whispering to each other. Both gentlemen came back, and one of them then told us that it seemed that we were carrying a very dangerous object.

My sister and I just said, “Huh?” Of course, we were a little concerned, thinking that maybe someone put something dangerous in one of our bags when we weren’t looking.

One of the agents then started to unpack our bags. I kept asking what he was looking for and then the object in question finally appeared. It was our Cosima necklace. It’s a piece of jewelry, with large, metal triangular spikes.

My sister and I looked at each other and breathed a huge sigh of relief. We started laughing and explained to the two male agents that it was just a necklace from our collection, not a weapon of mass destruction. They thought we were lying, and one agent kept repeating that he believed it was a weapon.

I tried to explain that we were jewelry designers going to a trade show, and this was simply a piece from our collection. But the agents didn’t buy it. Then a few women guards came over to assist. One of the women guards was holding an earring up to her ear and another was trying on a ring. Apparently, they liked our stuff.

It was only at this point that the male guards gave up. And I think they also got tired of listening to a bunch of women talk about jewelry. They let us through.

We took the names of the women agents and sent them a piece of jewelry when we got back to say thanks.

1.When the object in question finally appeared, the writer and her sister felt _______.

A. anxious　　         B. relieved　　　         C. excited　　　         D. frightened

2.The writer and her sister were stopped by the agents because ________.

A. their suitcases were too heavy

B. the agents wanted to play a joke on them

C. they were suspected to carry dangerous objects

D. the agents wanted to admire the jewelry inside the suitcases

3.The underlined word “buy” in Paragraph 7 probably means ________.

A. doubt　　　　         B. believe　　　　         C. purchase　　         D. understand

4.The writer sent the women agents a piece of jewelry in order to ________.

A. persuade them to buy her jewelry later

B. get help from them next time

C. show them her talent in designing jewelry

D. show them her gratitude for their assistance

5.According to this passage, which of the following statements is NOT true?

A. Someone put something dangerous in one of the writer’s bags.

B. The male agents didn’t believe the writer at first.

C. The female agents liked the jewelry.

D. The writer is always travelling on business.
