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.，，

I climbed the stairs slowly，carrying a big suitcase，my father following with two more. By the time I got to the third floor，I was 1 and at the same time feeling lonely. Worse still，Dad 2 a step and fell，sending my new suitcases 3 down the stairs. “Damn!”he screamed，his face turning red. I knew trouble was ahead. Whenever Dad"s face turns red， 4 ！
How could I ever 5 him to finish unloading the car without screaming at me and making a scene in front of the other girls，girls I would have to spend the rest of the 6 with？Doors were opening and faces peering out(探出)，as Dad walked with difficulty close behind. I felt it in my bones that my college life was getting off to a(n) 7 start.
“Enter the room quickly，”I thought. “Get him into a chair and calmed down.” But then again，would there be a chair in Room 316？Or would it be a(n) 8 room？
Finally I turned the key in the lock and 9 the door open，with Dad still 10 about a hurting knee or something. I put my head in， 11 the worst. But to my 12 ，the room wasn"t empty at all！It had furniture，curtains，a TV，and even paintings on the walls.
And there on a wellmade bed sat Amy，my new roommate，dressed neatly. Greeting me with a nod，she said in a soft voice，“Hi，you must be Cori.” Then，she 13 the music and looked over at Dad. “And of course，you"re Mr.Faber，”she said， 14 .“Would you like a glass of iced tea？”Dad"s face turned 15 less red before he could bring out a “yes.”
I knew then that Amy and I would be friends and my first year of college would be a success.

Let’s analyze this remarkably unsophisticated metaphor concerning love and the rose to see what it offers. Because the poet uses a comparison with a rose, first we must examine the characteristics of that flower. A rose is spectacular in its beauty; its petals(花瓣) are nicely soft, and its smell is pleasing. It’s possible to say that a rose is actually a feast to the senses of sight, touch, and smell. The rose’s appearance seems to border on(近似于)perfection, each petal seemingly symmetrical(对称的) in form. Isn’t this the way one’s love should be? A loved one should be a delight to one’s senses and seem perfect. However, there is another dimension added to the comparison by using a rose. Roses have thorns(刺). The poet wants to convey the idea that roses can be tricky(机警的). So can love, the metaphor tells us. When one reaches out with absolute trust to touch the object of his or her affection, ouch, a thorn can cause great harm! “Be careful,” the metaphor warns: Love is a feast to the senses, but it can overwhelm us, and it can also hurt us and cause acute suffering. This is the poet’s perception of love--a warning. What is the point? Just this: It took almost 14 sentences to clarify what a simple metaphor communicates in only four words! That is the artistry and the joy of the simple metaphor.
小题1:According to the passage, what is a metaphor?
| A．A comparison between two different objects with similar features. |
| B．A contrast between two different things to create a vivid image. |
| C．A description of two similar objects in a poetic way. |
| D．A literary device specially employed in poetry writing. |

| A．protect the rose from harm | B．symbolize reduced love |
| C．add a new element to the image of love | D．represent objects of one’s affection |
| A．love is a true joy | B．true love comes once in a lifetime |

The Millennium Seed Bank Project, run by Kew Gardens—one of the oldest botanical gardens—will officially deposit the 24,200th species on Thursday, a pink, wild banana from China.
More than 50 countries are now on board with Kew"s giant task but vast places of the globe, including India and Brazil, still need to join in and donate seeds, director Paul Smith said.
The seed bank is one of the largest and most diverse in the world with more than 1.5 billion seeds. Its goal is to help protect the planet’s bio-diversity during a time of climate change.
The wild banana seed is under threat of extinction(灭绝) in southwest China from agricultural development. It is a vital food source for Asian elephants and important for growing bananas for human consumption.
Stored at minus-20 degrees centigrade, so they can last for thousands of years, the seeds await the day that scientists hope never comes—when the species no longer exist in the wild.
It is a race against time, Smith said, because in the last decade alone, 20 plants held in the bank have already been wiped out in the wild. He estimates that between a third and a quarter will become extinct this century.
"It is urgent a
nd it is happening now. An area, the size of England, is cleared of primary vegetation（植被）every year." Smith said. Because most of the world"s food and medicines come from nature, protecting wild plant species is quite important, scientists say. There are already many other seed banks safeguarding food crops, which only account for 0.6 percent of plant diversity.
For Kew"s next goal—to collect a quarter of wild varieties by 2020—the botanists need 10 million pounds a year, or a further 100 million pounds on top of the 40 million they have already been granted.
小题1:What’s the final purpose of the Britain’s seed bank?
| A．To collect enough money for the project. | B．To safeguard food crops. |
| C．To protect wild plants from extinction. | D．To help scientists study wild plants. |
| A．the expanding of farming work | B．the climate change in this area |
| C．the large number of Asian elephants | D．human’s large consumption |
| A．the seeds in the bank can be used now and then all over the world |
| B．India and Brazil haven’t joined in the Seed Bank Project at present |
| C．there is only one seed bank in the world at present |
| D．the wild plants in places like India and China will never die out |
| A．The extinction of plant species. | B．The Millennium Seed Bank Project. |
| C．Britain’s seed bank. | D．Kew Gardens’ next goal. |
| A．The global partnership of collecting wild plant species. |
| B．The temperature condition of the conservative wild plant species. |
| C．The government’s financial support for the seed bank project. |
| D．Scientists’ concern on the extinct wild plant species. |
But experts are now warning that the current shoe fashions will be causing teenagers discomfort in the short term and storing up years of foot, knee and back pain in the future.
Here, the experts identify the problems caused by teenagers" shoe choice.
KEDS/VANSSlip-on shoes with elastic (弹性的）sides are particularly popular among teenage boys - with Keds and Vans the most sought-after brands.
The main problem is that they are just too flat—so flat that the heel, which strikes the ground first, also becomes damaged and painful.
BALLET PUMPS
The worst shoes of all are such light and thin dolly shoes. The problem is partly their flatness, as with Keds and Vans. However ballet pumps, which have no string or heel, have other specific problems. “As the shoe has no fastening device, it relies on the toes to keep the shoe on, causing an awkward gait（步法）, this leads to short- and long-term problems such as calluses（茧子）, heel and knee pain.”
WEDGES AND STILETTOS
These shoes can also cause problems with gait. They may look good, but the heels on these are so high they can force the wearer"s body weight forward, making them very unstable.Teens who wear these shoes regularly are also in danger of joining those millions of women with constant back pain.
SCHOOL SHOES
So what do podiatrists（足科医生）have on their wish list, especially for everyday wear?
Something in a natural, breathable fabric, with a string to hold it on, with a small heel and a deep toe-box that does not press the toes, such as Clark"s, Marks & Spencer or Rhino.
If your teen insists on wearing "bad" shoes, get them some simple foot orthotics(矫形器) in the shoes. These support and correct the movement of the foot and, properly fitted by a podiatrist, can often transform their walk and halt the damage.
小题1: Of all the shoes mentioned in the passage, which can cause the worst problems?
A．Marks & Spencer . | B．Wedges & Stilettos. |
| C．Keds and Vans. | D．Ballet Pumps. |
小题3: The underlined word “halt” in the last paragraph probably means _______.
| A．increase | B．worsen | C．stop | D．cure |
| A．trendy shoes may ruin teenagers’ health |
| B．fashionable shoes all have orthotics in them |
| C．experts are strongly against wearing popular shoes |
| D．podiatrists are expert at producing branded shoes |
| A．Sports. | B．Science. | C．Health. | D．Shopping. |
