A low-carbon lifestyle means cutting carbon dioxide emissions and living a life characterized by low-energy use, low consumption and low spending. This way of living is being accepted by a growing number of average people in China.
Before low-carbon became a popular word here, some environmentally conscious people known as "Lohas" had already devoted themselves to living green, low-carbon lifestyles. Lohas is for "lifestyles of health and sustainability." It was first introduced in 1998 by American sociologist Paul Ray and later became a popular lifestyle in western countries. After this concept was introduced into China a few years ago, Lohas was translated into a proper Chinese word "lehuo," meaning happy living.
Zhang Tao from a joint venture in Beijing is a Lohas supporter and follower. He and some others set up a Lohas club two years ago. They often get together to share their experiences about living green lifestyles or to volunteer for environmental protection activities.
Zhang says Lohas is both a lifestyle and an attitude towards life rather than just a fashion or slogan.
"A Lohas lifestyle means a natural and healthy life with low costs. We don't drive cars, and we try our best to save water and electricity. Some people misunderstand us as being too stingy. But in fact, most of us are well-paid. We don't do it to save money, but for the sake of the environment. Living a rich life doesn't mean you can waste resources. We hope what we do can help save energy and reduce the pressures on earth. I know our personal strength is too small, but the changes will be great if everyone can make a little contribution."
64. A low-carbon lifestyle has the following features except_______.
A. low energy B. low wages C. low consumption D. low spending
65. A Lohas is most likely to_______.
A. drive a car to work every day B. save money to live a better life
C. turn off the tap when not using D. leave the light on day and night
66. What does the word “stingy” mean in the last paragraph?
A. generous B. mean C. rich D. willing
67. In Zhangtao’s opinion, _________.
A. Lohas is just a fashion or form B. one shouldn’t get well paid
C. one should live a happy life D. environment protection depends on everyone

We all think plants were expected to get larger with increased carbon dioxide in the atmosphere, but changes in temperature, humidity(湿度)and nutrient availability seem to have trumped the benefits of increased carbon dioxide” said researchers from the National University of Singapore.
45 percent of the species studied now reach smaller adult sizes than they did in the past. The researchers pointed out that warmer temperatures and changing habitats, caused by climate change, are possible reasons for shrinking creatures.
“ We do not yet know the mechanisms(机制)involved, or why some organism are getting smaller while others are unaffected,” the researchers said. “Until we understand more, we could be risking negative consequences that we can’t yet quantify. ’’
The change is big in cold-blooded animals. Only two decades of warmer temperatures are enough to make retiles (爬行动物)smaller. An increase of only 1 degree centigrade caused nearly a 10 percent increase in metabolism(新陈代谢). Greater use of energy resulted in tiny tortoises and little lizards. Fish are smaller now too. Though overfishing has played a part in reducing numbers, experiments show that warmer temperatures also stop fish growing.
Warm-blooded animals aren’t immune(免除)from the size change caused by climate change. Many birds are now smaller. Soay sheep are thinner. Red deer are weaken And polar bears are smaller, compared with historical records.
This is not the first time this has happened in Earth’s history. 55 million years ago, a warming event similar to the current climate change caused bees, spiders and ants to shrink by 50 to 75 percent over several thousand years. That event happened over a longer time than the current climate change.
The speed of modem climate change could mean organisms may not respond or adapt quickly enough, especially those with long generation times climate change will be shown in the future.
1.What does the text mainly talk about_______
A. Why some species become smaller.
B. How climate changes in Earth’s history?
C. Climate change has many negative effects.
D. Species are becoming smaller as climate gets warmer.
2.The underlined word “trumped” m the first paragraph probably mean_________.
A. strengthened B. gained
C. beaten D. equaled
3.Researchers from the National University of Singapore believe that________
A. they have found the exact causes for creatures getting smaller.
B. all the animals on the earth have become smaller.
C. climate change has more negative effects on warm-blooded animals.
D. increase in energy use can lead to creatures getting smaller.
4.What does the author feel about the climate change?
A. Disappointed B. Optimistic
C. Worried D. Shameful

Rising levels of carbon dioxide in the atmosphere are a major cause of climate change, and now a new study has confirmed that atmospheric CO2 is also affecting the ocean chemistry and potentially harming sea life.
Montana State University scientist Robert Dore has been researching the water in the Pacific Ocean for almost two decades.
"We've been going to the same spot in the Pacific Ocean, and we try and characterize long-term change in the open ocean environment. And one of the key things that we measure is CO2 levels. And we've been able to record this increasing quantity of atmospheric CO2 into the ocean."
Scientists expected that as atmospheric CO2 increased, more and more of the carbon dioxide would be absorbed into the ocean, affecting the chemical balance of the sea water, with a potentially harmful impact on shellfish and coral in particular.
"As carbon dioxide dissolves(溶解) in the water, or seawater in this case, it forms a weak acid, carbonic acid," Dore explains. "And therefore, as the concentration of CO2 in the atmosphere goes up and that exchanges with the surface seawater, it drives the pH down, and makes it more acidic."
The seawater Dore and his colleagues have analyzed confirms what the theory predicts.
The effect was particular striking at about 250 meters down, and again at 500 meters. Dore and his colleagues came up with two possible explanations. It could be that surface water picked up CO2 and then moved to those depths. Or there could be a biological explanation.
"It's important to realize that the oceans are really becoming acidic. And it can have negative impacts on a whole variety of sea life from fish to coral. It's potentially catastrophic."
1.What can be the best title of the passage?
A.Sea Life Facing Danger B.Climate Change Affecting Seawater
C.Oceans Becoming More Acidic D.Scientist Researching Seawater
2.Which of the following shows the process of the impact of atmospheric CO2 on sea life?
a.Sea life is endangered.
b.CO2 goes into the surface water.
c.The ocean chemistry is affected.
d.CO2decreases the PH and makes the seawater more acidic.
e.CO2 levels in the atmosphere go up.
A. a → b → c → d → e
B. e → b --→ c → d → a
C. a → e -→ b → c → d
D. e → d -→ c → b → a
3.Scientist Robert Dore came to the conclusion based on________ .
A.his research and analysis
B.a major cause of climate change
C.some former theory
D.the expectation of other scientists
4.What does the passage want to tell us most?
A.It takes time to make a scientific study.
B.Atmospheric CO2 is doing harm to sea life.
C.Robert Dore is a committed and serious scientist.
D.Measures should be taken to prevent the potential catastrophe.
