The amount of carbon taken in by growing plants increased from 1982 through 1999 as
temperatures rose and the amount of carbon dioxide in the atmosphere increased. But a new study
in Friday ’ s edition of the journal Science found a drought - related decline in such plant growth
from 2000 to 2009，even though temperatures continued to climb.
As drought caused by warming reduces the land ’ s ability to take in carbon，the result could
be more carbon dioxide left in the atmosphere，and thus more warming，Zhao Maosheng from the
University of 
Montana explained in a telephone interview.
“This is a pretty serious warning that warmer temperatures are not going to endlessly improve
plant growth ’” co - author Steven Running，also from the University of Montana ’ said in a
statement. “ We see this as a bit of a surprise，and potentially significant on a policy level because
previous interpretations suggested global warming might actually help plant growth around the
world, “ he said.
Instead, he and Zhao found a small but measurable decline of about 1%，compared to a6%
increase in the past decade.
Their study，based on the data collected by NASA satellites，found that north areas continued
to increase plant growth，thanks to warmer temperatures and a longer growing season.
Someone commented, "This past decade’ s net decline in earthly productivity suggests that a
complex relationship between temperature, rainfall, cloudiness, and carbon dioxide, probably in
combination with other factors such as nutrients(营养）and land management，will determine
future patterns and trends in productivity.，，
【小题1】From the first paragraph, we can learnin 
the recent decade or so.
| A．the emission(排放)of carbon hasn’ t been reduced |
| B．draught has been causing loss of soil and water |
| C．carbon dioxide levels have been rising |
| D．the rise of temperature doesn' t promote the plant growth |
E. more and more land will be abandoned
F. the climate becomes warmer and warmer
G. the emission of carbon dioxide increases
H. draught further reduces the number of the plants
【小题3】Steven Running made his statement to .
I. confirm Zhao' s views on the influence of temperature rise
J. urge the government to take necessary measures
K. warn the people to strengthen the plant protection
L. support Zhao* s views on lhe plant production
【小题4】We can infer from the passage that .
| A．global warming will determine the future productivity |
| B．various factors play a key role jointly on future productivity |
| C．earthly productivity actually increased in the past decade |
| D．temperature rise has had no effect on future producticity patterns |
根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项。
When I was a little girl, my mom would say, “Half the fun of doing anything is sharing it with others.” 1 Friends and mates allow us to enjoy our successes and our joys, comfort us in our hard moments, and provide a mirror for us to learn more about ourselves. I’ve always looked at friends as the family we choose. They enrich our lives. As Robert Louis Steven once said, “ 2 ”
To be a good friend or partner, it’s important to be a good listener. Hear what your friend or mate has to say first rather than jump to conclusions or get defensive. 3 When they hear their words repeated back to them, it can help them to realize what they said was not exactly what they meant to say.
4 You know the old golden rule, “Care for others the way you would like them to care for you.” The support of a friend during a tough time could make the difference between success and failure. Encouragement and confidence are the gifts that can help change a person’s life.
Take care, though, with whom you choose to have close relationship, for they can have a great effect on yourself – respect and life path. As someone once told me “ 5 They will either take you up or down.”
| A．I am afraid so. |
| B．It is quite true |
| C．Friendship is the most important factor. |
| D．Sometimes it is useful to be their mirror. |
F．The attitudes of your friends are like the buttons on a lift.
G．Patience, sympathy and understanding are also important qualities.
