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 a 6%

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.，^，

From the first paragraph, we can learn in the recent decade or so.

the emission(排放)of carbon hasn’ t been reduced

draught has been causing loss of soil and water

carbon dioxide levels have been rising

the rise of temperature doesn' t promote the plant growth

Zhao Maosheng really worried that  .

more and more land will be abandoned

the climate becomes warmer and warmer

the emission of carbon dioxide increases

draught further reduces the number of the plants

Steven Running made his statement to   .

confirm Zhao' s views on the influence of temperature rise

urge the government to take necessary measures

warn the people to strengthen the plant protection

support Zhao* s views on lhe plant production

We can infer from the passage that    .

global warming will determine the future productivity

various factors play a key role jointly on future productivity

earthly productivity actually increased in the past decade

temperature rise has had no effect on future producticity patterns

The amount of water in the world is finite(有限的). The number of people is growing fast and water use is growing even faster. Global water consumption rose six times between 1900 and 1995—more than double the rate of population growth.

As important as quantity is quality—with pollution increasing in some areas，the amount of useable water declines.

And the wider effects of water shortages are just as frightening as the prospect of having too little to drink.

Seventy percent of the water used worldwide is used for agriculture. Much more will be needed if we are to feed the world's growing population. And consumption will rise further as more people expect Western－style lifestyles and diets—one kilogram of grain－fed beef needs at least 15 cubic metres of water，while a kilo of cereals(谷物)needs only up to three cubic metres.

New technology can help，however，especially by cleaning up pollution and so making more water useable，and in agriculture，where water use can be made far more efficient.

Drought－resistant(抗旱的)plants can also help.

The optimists say“virtual water”may save the day—the water contained in crops which could be exported from water－rich countries to dry ones. But the amounts involved would be huge，and the energy needed to transport the water would be enormous(巨大的).

In any case，it is not just us who need water，but every other species that shares the planet with us. We have to rethink how much water we really need if we are to learn how to share the earth's supply. While dams and other large－scale schemes play a big role worldwide，there is also a growing recognition of the value of using the water we already have more efficiently rather than harvesting ever more from our rivers. For millions of people around the world，getting it right is a matter of life and death.

1. Which of the following statements on water consumption is NOT true?

A. Agriculture consumes more than haft of the water used in the world.

B. The growing population worsens the water shortage situation.

C. Lifestyles play an important role in water consumption.

D. The Western way of agriculture uses more water than the Asian way.

2. “Virtual water” refers to the water that ________.

A. is hidden in crops

B. is saved in agriculture

C. can be transported

D. can be reused with the aid of the Internet

3. In the last paragraph，the author mainly ________.

A. criticizes big projects such as dams

B. criticizes the use of river water

C. calls for the protection of other species

D. calls for the more efficient use of water

4. What's the main idea of the text?

A. Water is mainly wasted in agriculture.

B. Water pollution is threatening our health.

C. Shortage of water is a very serious problem.

D. Population growing influences water use.

The area of child psychology is one of the most significant and well studied of all the branches of psychology. It aims to help with achieving a greater understanding of the behavior of children through an understanding of their minds. It deals with children who range from the prenatal(出生前的)stage right up to the stage of adolescence.
The psychologist Jean Piaget (1896-1980) has been credited with making a major breakthrough in this area when he put forward his idea that children were not actually less intelligent than adults, rather they just thought in a different way. Preciously the development of children right from birth through to adulthood was an area that was almost completely neglected. In fact very little work was done in this area. However, interest in this field has now developed to the point of being one of the most debated of all the areas of psychology.
Despite popular belief that factors such as genetics or personal characteristics are the only determining factors that influence a youth’s behavior, this is not in fact the case. In reality, development actually includes many more factors than those contained within an individual. Factors such as environment, which can include social relationships and the surrounding culture, also play important roles. Relationships with both peers and adults will no doubt affect how children think and learn, and therefore develop. These relationships can include those that are found not only within families but also in schools and peer groups.
Culturally speaking, this factor will contribute greatly to how children develop their personality concerning the values they end up holding (perhaps for a lifetime) as well as how they view such things as traditions and customs.
Nowadays, psychologists have agreed that a child’s psychology is both unique and highly complex. However, there are debates on many different points in this field and many viewpoints exist.

C．compare some of the areas of psychology.

The world of the science-fiction 3-D film Avatar is so perfect that the line between fact and fiction has become somewhat blurred (模糊) .

Movie-goers have admitted being annoyed by depression at not being able to visit the planet Pandora. Set in the future when Earth’s resources have been used up, director James Cameron’s film tells the story of a company trying to exploit a rare mineral on a new planet. The humans clash with the natives—a peace-loving race of 7-foot-tall, blue-skinned creatures called the Na’vi, who exist in perfect harmony with nature.

Fans have flooded the Internet with their confused feelings. On the site Avatar Forums (论坛), the topic “Ways to deal with the depression of the dream of Pandora not being able to come true” has more than 1,000 posts. In a similar forum, Louis, one user, wrote: “When I woke up this morning after watching Avatar for the first time yesterday, the world seemed grey. It just seems so meaningless. I still don’t really see any reason to keep doing things at all. I live in a dying world.” On the Avatar site Naviblue, a fan calling himself Jorba has even asked others to join him in starting a real Na’vi tribe.

This fantasy world, with its wonderful plants and animal life, is brought to life by using impressive special effects. Many people believe that 2010 is the breakthrough year for the technology helped by 3-D movies such as Avatar. “It has taken the best of our technology to create this virtual world and real life will never be as perfect as it seems on screen. It makes real life seem more imperfect.”
