8、Backpacking through Africa, I always carried some food with me 1 I couldn’t find something to eat．
I was 2 through a local market one day when I 3 upon a jar of 4 jam．I could find tins of apple and strawberry in every corner store but this was the first time I had seen peach．I took it．
For the next few weeks, when I was feeling the need for a little 5 , I would carefully 6 the lid and spoon a bit on to a biscuit．Mum, delicious．I didn’t 7 it with anybody．It sat safely in my 8 , taken out on only special 9 ．
One cold and cloudy afternoon, while I was waiting for a local bus, it started to rain．Everybody scattered for 10 and so did I．But I was already wet through so I quickly searched through my pack for some 11 clothes．
In my hurry to 12 further discomfort, I forgot that the jar of jam was 13 in my clothing．One forceful yank（猛拉）and my 14 jar of jam crashed to the concrete ground, smashing into pieces．
I was so sad that I almost cried．And then, in the corner of my eye, I noticed an old woman in rags 15 ．Without hesitating, she bent down and picked up the half of the jar that still looked 16 ．
Still 17 , she stuck two fingers into the jar, scooped out the 18 jam and placed it into her toothless mouth．Carefully, like fish bones, she 19 the pieces of glass．She studied the broken container 20 she was certain that there was nothing left．Then she left．
My bus arrived shortly after and, as we drove off, I wondered if the jam would taste the same to me．

7、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 ago．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 heating 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 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 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 Strats at Home B．Changing Our Habits Begins at Work
C．Changing Climate Sounds Reasonalbe D．Reducing Emissions of CO2 Proves Difficult
6、Many people think the search for cleaner energy leads only to renewable resources like sun, wind and water．But it also leads to a fossil fuel．Natural gas is considered the cleanest of the fossil fuels, the fuel created by plant and animal remains over millions of years．Burning it releases fewer pollutants than oil or coal．The gas is mainly methane （甲烷）．It produces half the carbon dioxide of other fossil fuels．So it may help cut the production of carbon gases linked to climate change．
Russia is first in what are called "proved reserves" of natural gas．The United States is sixth．Over the years, big oil and gas companies recovered much of the easily reached supplies of gas in America．They drilled straight down into formations where gas collects．As these supplies were used up, big drillers looked for similar formations in other countries．
But now the industry is taking a new look．Companies are developing gas supplies trapped in shale （页岩） rock two to three thousand meters underground．They drill down to the shale, then go sideways and inject high-pressure water, sand or other material into the rock．This causes the rock to fracture, releasing the gas．Huge fields of gas shale are believed to lie under the Appalachian Mountains, Michigan and the south-central states．Gas shale exploration is being done mainly by small to medium sized companies．Eric Potter, a program director, says more than half the gas in the United States is now coming from these new reserves．
But hydraulic （液压的） fracturing can also produce debate and anger over the risk of groundwater pollution．This method of drilling is not federally supervised under the Safe Drinking Water Act．Some in Congress want to end that exemption （豁免） from the law．
Natural gas provides Americans with about one fourth of their energy．And, unlike oil, most of it is produced in America．Gas producers invested heavily in reaching new supplies when prices were high．But prices are down sharply now because the depression cut demand for energy．So energy expert Eric Potter says it is too early to know how the changing market prices will affect the market for gas shale exploration．
1．We can learn from the first paragraph that ________．
A．natural gas releases methane and carbon dioxide
B．natural gas is considered as the cleanest energy
C．natural gas is more environmentally friendly than other fossil fuels
D．natural gas is a renewable source of energy
2．The word “fracture” in Paragraph 4 probably means _______．
A．create B．break C．change D．decrease
3．Gas shale exploration may cause disagreement because ______．
A．it may cause water pollution B．it brings too high profits
C．it breaks the law D．it is out of states’ control
4．According to Eric Potter, the new gas shale exploration ______．
A．will provide America with about one fourth of their energy
B．will increase demand for energy
C．will make gas producers invest a big sum of money
D．may be influenced by the changing market prices
