【题目】The planet is getting greener, and we are responsible. Carbon dioxide generated by human activities is promoting photosynthesis (光合作用) and causing a beneficial greening of the Earth’s surface.
For the first time, researchers claim to have shown that the increase in plant cover is due to this “CO2 fertilisation (肥沃化) effect” rather than other causes. However, it remains unclear whether the effect can reduce any negative effects of global warming, such as the spread of deserts.
To home in on the effect of CO2, Randall Donohue of Australia’s national research institute, the CSIRO in Canberra, monitored vegetation (植被) at the edges of deserts in Australia, southern Africa, the US Southwest, North Africa, the Middle East and central Asia. These are regions where there is plenty of warmth and sunlight, but only just enough rainfall for vegetation to grow, so any change in plant cover must be the result of a change in rainfall patterns or CO2 levels, or both.
If CO2 levels were constant, then the amount of vegetation per unit of rainfall ought to be constant, too. However, the team found that this figure rose by 11 per cent in these areas between 1982 and 2010, mirroring the rise in CO2 emissions (排放). Donohue says this lends strong support to the idea that CO2 fertilization drove the greening.
The extra plant growth could have knock-on effects on climate, Donohue says, by increasing rainfall, affecting river flows and changing the likelihood of wildfires. It will also absorb more CO2 from the air, potentially damping down (抑制) global warming but also limiting the CO2 fertilization effect itself.
Donohue cannot yet say to what extent CO2 fertilisation will affect vegetation in the coming decades. But if it proves to be significant, the future may be much greener.
【1】According to the author, the increase in plant cover _____.
A. will speed up global warming
B. results from human activities
C. will stop the spread of deserts
D. promotes the CO2 fertilization effect
【2】What does the underlined phrase “To home in on” in Para 3 probably mean?
A. To hold back. B. To cut down.
C. To improve. D. To observe.
【3】 The amount of vegetation in those monitored areas rose with _____.
A. the rise in CO2 emissions B. annual rainfall
C. the temperatures around D. the amount of sunlight
【4】What’s the best title of the text?
A. More rainfall, less CO2 emission
B. How to deal with carbon emissions
C. Positive effects of global warming
D. CO2 emission making Earth greener

【题目】A: Taking care of yourself is not being selfish. By caring enough to treat your body well, you will be in better shape to take care of those around you. No one can take care of your health except yourself;
B: Believe in yourself and your ability. Have a “can-do” attitude. Make a list of successful changes that you have made in the past. It is easier to achieve a goal when you are optimistic. Use humor and laugh off occasional lapses (过失). Have confidence that you can get back on track with your healthy routine.
C: Seek out a friend or co-worker who will make you feel comfortable. You will find out making friends is a happy thing in the world. Regular phone calls, emails or visits over coffee could help you keep a good contact with them. Perhaps your cheerleader could become your exercise buddy.
D: Reward yourself as you make simple changes that in the end will result in achieving your overall goal. Celebration is part of successful change. Create a list of incentives that will keep you motivated.
E: Adopt eating and physical activity habits that can become part of your lifestyle. Have a backup plan for those days when your plans to eat well and be active are challenged. If you can’t walk due to the weather, have an exercise video to use. If you have no time to pack a healthy lunch, choose a small fast food sandwich and side salad.
F: Go on a trip. Work and family are two most important things in people’s lives. People try to tackle the two things at once, but most of them fail. Just as an old saying goes: People who know how to rest know how to work. Go out with your family and have a good time.
