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.，^，

1.From the first paragraph, we can learn in 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

2.Zhao Maosheng really worried that__ .

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

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

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

Companion planting is the idea that some kinds of plants can help each other grow. Plants that are compatible together generally have similar needs in terms of nutrients, soil and moisture levels.

Advice about which plants are compatible is sometimes based more on tradition than proof. But experts say there is evidence to support certain combinations. These can improve harvests, reduce disease and help with pest control by attracting helpful insects.

For example, some kinds of soil bacteria take nitrogen from the air and make it into a form that plants can use. The plants hold the nitrogen in their roots. Legumes（豆科植物）are especially good at this nitrogen（氮）-fixing. Then any crops that share the same space with the legumes can get the nitrogen when the roots are broken down.

Beans and potatoes can also share territory well because their roots reach different levels in the soil. Deep-rooted vegetables get nutrients and moisture from lower down in the soil, so they do not complete with plants with shallower roots.

But some plants placed together may harm each other’s development. For example, tomatoes do not like wet soil but watercress does, so you would probably want to keep them separated.

Some kinds of produce should be kept apart even after being harvested. This is because of ethylene gas（乙烯气体）. Ethylene is a plant hormone（激素）that can cause some foods to ripen too quickly. Apples release ethylene gas. Apricots, melons and tomatoes also release a lot of ethylene. Some vegetable are easily affected by ethylene, including asparagus, broccoli, cabbage and cucumbers.

This risk of ripening too soon is why markets often separate high ethylene-producing foods from those that are sensitive to the gas. But if you put an apple in a bag with a green banana, the ethylene from the apple will make the banana ready to eat sooner.

What about peaches, plums and nectarines? These kinds of fruit do not need any help from an apple—they release enough ethylene to ripen themselves. But that does not mean there is no way to get the job done faster.

Growers suggest placing the fruit in a fruit bowl or in a paper bag with the top folded over. Keep the fruit at room temperature, out of direct sunlight. Once the fruit is soft enough, either use it or put it in the refrigerator to keep it from getting too ripe.

1.Companion planting refers to the idea that ________

A. some crops can grow together to benefit each other.

B. some crops have the similar needs of nutrients, soil and water level.

C. some plants can damage each other if grown together.

D. a good farming method to prevent natural disasters.

2.According to the text, ________cannot grow together.

A. beans and potatoes　　 B. tomatoes and watercress

C. legumes and corns　　 D. rice and sugarcane

3.What is the function of ethylene?

A. To improve the quality of fruits.　　 B. To produce a poisonous gas.

C. To keep vegetables fresh.　　 D. To make fruits ripe earlier.

4.The text is most likely to be taken from ________.

A. a newspaper of medicine　　 B. a magazine of biology

C. a journal of agriculture　　 D. a travel report

There is a growing number of kidults---or adults who wear the mask of maturity but prefer to pander(迎合) to their inner child.

They feel ill equipped for parenthood, because they don’t see what values or lessons they could honestly pass on to their young, besides self-centeredness and a passion for the good things in life. They are trying to live by not acting their age.

As Ms Jane put it in her letter: I’m married, in my late 20s and enjoy a lifestyle other married graduate couples enjoy: winning and dining, tasteful clothes, travel and a career. Why give up all these for a baby?

It is reported that when asked whether they were adults, most people in their 20s answered they were not sure. This reflected a global economy in which people chased more papers to get better jobs that would comfortably support middle class living.

Being a kidult is not all about being selfish, though. With the untold uncertainties of war, fluctuating(波动)markets, disease and terrorism, many see this world as a poor place to live in—let alone bring kids up in. This seems especially so in urban living. All anyone wants after a long, hard day at work is some peace and quiet.

My classmate, Jenny, mused(沉思)recently how our friends living in small Malaysian towns were onto their second or third kids. Maybe they just loved having children around. Or maybe, in their own way, they wanted to leave the world a better place than they found it.

That’s how you, I and everyone know we have the chance to breathe air, touch grass and see sky. I think out parents understand that just being alive is an experience worth passing on.

1.What is a kidult in the writer’s opinion?

A. A person who doesn’t have a child

B. An adult who actually has a psychology of a child

C. A child who doesn’t want to grow up

D. A person who doesn’t know that what values he has

2.What does the underlined word “paper” in Para. 4 mean?

A. money

B. reputation

C.qualification

D. power

3.The author explains the kidult phenomenon by ________.

A. presenting research findings

B. making comparison

C. showing her own experience

D. using examples

4.We can learn from the text that kidults________.

A. know little what they can pass on to their children

B. are sure of their abilities for good life

C. living in urban can enjoy more peace

D. living in small towns know well what they’re living for
