Passenger pigeons（旅鸽）once flew over much of the United States in unbelievable numbers. Written accounts from the 18th and 19th centuries described flocks（群）so large that they darkened the sky for hours.
It was calculated that when its population reach its highest point, there were more than 3 billion passenger pigeons – a number equal to 24 to 40 percent of the total bird population in the United States, making it perhaps the most abundant birds in the world. Even as late as 1870 when their numbers had already become smaller, a flock believed to be 1 mile wide and 320 miles (about 515 kilometers) long was seen near Cincinnati.
Sadly, the abundance of passenger pigeons may have been their undoing. Where the birds were abundant, people believed there was an ever-lasting supply and killed them by the thousands. Commercial hunters attracted them to small clearings with grain, waited until pigeons had settled to feed, then threw large nets over them, taking hundreds at a time. The birds were shipped to large cities and sold in restaurants.
By the closing decades of the 19th century, the hardwood forests where passenger pigeons nested had been damaged by Americans’ need for wood, which scattered（驱散）the flocks and forced the birds to go farther north, where cold temperatures and spring storms contributed to their decline. Soon the great flocks were gone, never to be seen again.
In 1897, the state of Michigan passed a law prohibiting the killing of passenger pigeons, but by then, no sizable flocks had been seen in the state for 10 years. The last confirmed wild pigeon in the United States was shot by a boy in Pike County, Ohio, in 1900. For a time, a few birds survived under human care. The last of them, known affectionately as Martha, died at the Cincinnati Zoological Garden in September 1, 1914.In the 18th and early 19th centuries, passenger pigeons _______.

Growing strawberries in pots
·The best way to start growing strawberries is to buy pot-grown strawberry plants m spring：5 plants are plenty for a hanging basket and 10 for the average 13 inch-sized pot．
·Plant them immediately in soil-based compost（混合肥料） and they will produce a modest crop in their first year．The second year should see a bumper（特大的）crop，followed by a slightly lower yield（产量）the third summer ．Then start again with fresh stock ．
·Careful watering and feeding are essential If you are to harvest a good crop，you must never let the compost dry out, particularly when the fruit is forming and ripening；if you do．most of your crop will drop off血e bush almost immediately．
·Water well then leave the pots for up to 3 weeks，until they reach the point of drying out be careful not to overwater them during the winter months．
Pruning apple trees
·A one-year-old tree is known as a “maiden”．It has a single stem when purchased．Immediately after planting, cut it back by about half to leave 4 good buds at the base of the stem．．This will force growth from the base or the plant during the summer．
·In the second year ,prune in winter by cutting all side branches back by about one-third, Make sure each cut is made cleanly just above an outward-facing bud．In the third and fourth years, new side branches will have emerged from the previous year’s growth．Cut back all these new side branches by a third, pruning to an outward-facing bud．
·By the fifth year the tree should have a well-balanced shape．From then on ,cut back all new branches by one-third in winter．Remove any diseased wood and broken branches, and ensure the centre is open to air circulationThe two pieces of advice probably appear in_________
| A．a scientific repot | B．a gardening guide |
| C．a book review | D．a fashion column |

The breaking news of Mo Yan's Nobel Prize in Literature on Thursday evening soon aroused public curiosity of the 57yearold Chinese writer: Why was it him that was favored by the Swedish Academy?
Born in 1955 into a rural family，Mo dropped out of school and became a farmer when he was a teenager．He joined the military and devoted himself to writing after the Cultural Revolution （1966－1976）．
Less than half an hour after the announcement，Mo's works turned to soldout status at China's major online book sellers．One lucky buyer wrote in an online comment: “Rushed to purchase，but to my shame，I have not read any of his novels．”
Although Mo was entitled one of the top domestic literature awards before the Nobel Prize，he is not the most popular novelist in China，in either the book market or in reputation．
Mo's novel “Big Breasts & Wide Hips，” translated by Howard Goldblatt，tells a story of a mother who struggled and suffered hardship and intertwined fates with Chinese people in the 20th century．His more recent work “Frog” more directly criticized China's onechild family policy，which helped control the country's population explosion but also brought tragedies to rural residents in the past 60 years．
“I think the reason why I could win the prize is because my works present lives with unique Chinese characteristics，and they also tell stories from a viewpoint of common human beings，which is above differences of nations and races，” Mo said on Thursday evening to Chinese journalists．Mo also said many folk arts originated from his hometown，such as clay sculpture，paper cuts，traditional new yearpaintings，have inspired and influenced his novels．
With more Chinese writers like Mo，the world could learn a more real China．Perhaps，this is another reason for the Swedish Academy's choice．What can we conclude from the second paragraph?
| A．Mo's life experiences． |
| B．Mo's family life． |
| C．Mo devoted himself to writing． |
| D．Mo had a gift for writing． |
What can we infer from the passage?
| A．Mo didn't got any national awards before he won the Nobel Prize． |
| B．Mo was the top novelist in China before he won the Nobel Prize． |
| C．Mo's novels have attracted many people to read． |
| D．Mo's novels are all based on his daily life． |
Which of the following have no effect on Mo's novels according to the passage?
| A．Clay sculpture． | B．Paper cuts． |
| C．Folk arts． | D．Beijing opera． |
According to the passage，we know that________．
| A．Big Breasts & Wide Hips' leading role is one happy mother |
| B．Big Breasts & Wide Hips criticized China's onechild family policy |
| C．Frog came out earlier than Big Breasts & Wide Hips |
| D．Frog shows benefit as well as shortcoming of one China's policy |
The kindly “Chinese Fortune Grandpa” wearing Han Chinese clothing and holding a fortune bag debuted （亮相） at the Imperial Ancestral Shrine in Beijing on the day after Christmas．The final image of the Chinese gift-giver was selected through a global design competition against “Santa Claus”，according to a report by Guangming Daily．
Many Chinese cities have been filled with Christmas neon lights，Christmas songs，Christmas trees，and the images of “Santa Claus”in recent days．As a matter of fact，foreign festivals are becoming more popular than certain traditional Chinese festivals among the Chinese people，particularly the youth．“Certain traditional festivals have died out because people have forgotten their spiritual meanings，”said noted writer Feng Jicai．More and more Chinese people are beginning to exchange gifts on Valentine's Day and Christmas．However，many of them know nothing about Chinese New Year pictures or sugarcoated figurines（小糖人），and have never heard suona music．Certain folk customs on the Dragon Boat Festival，Tomb Sweeping Day，and other traditional festivals have gradually disappeared．Under such circum-stances，even the “Chinese Fortune Grandpa” is unlikely to defeat “Santa Claus”．
However，it is not a bad thing to some extent．It constantly reminds people to restore the “true face” of traditional festivals．China has listed traditional Tomb Sweeping Day，Dragon Boat Festival and Mid-Autumn Festival as legal holidays，which brings more paid leaves to the public，and helps to awake the public awareness of traditional festivals．
In modern society，festival is a carrier of culture and its meaning largely depends on their understandings and usages by people．Compared with foreign festivals，traditional Chinese festivals are not inferior （次于） in cultural meanings，but lack of fashion sought by modern people．If people do not appreciate the historical culture contained by traditional festivals，and only take pleasure-seeking as the most important，the significance of traditional festivals will fade away and the inheritance （继承） of fine traditional culture will be cut off．
The second paragraph implies that______________________．
| A．traditional festivals should co-exist with foreign festivals |
| B．all the Chinese festivals are disappearing in the near future |
| C．western festivals are constantly impacting on our festivals |
| D．the Chinese people have the public awareness of traditional festivals |
We can learn from the passage that______________．
| A．an image designed by the Chinese people will be displayed |
| B．the Chinese gift-giver was intended to symbolize traditional culture |
| C．many foreigners know nothing about Chinese festivals |
| D．the Chinese are beginning to exchange gifts on the Mid-Autumn Festival |
Many Chinese youth dislike traditional festivals because they think______________．
| A．traditional festivals are out of fashion now |
| B．the historical culture is more difficult to understand |
| C．western festivals contain more cultural meanings |
| D．the inheritance will cut off their contact with western festivals |
What would be the best title of the passage?
| A．Gone are Chinese Traditional Festivals |
| B．True Face of Chinese Traditional Culture |
| C．Foreign Festivals Popular with Chinese |
| D．Chinese Fortune Grandpa VS．Santa Claus |

Centuries ago, man discovered that removing moisture(潮湿)from food helps to store it, and that the easiest way to do this is to expose the food to sun and wind. In this way the North American Indians produce pemmican(dried meat ground into powder and made into cakes), the Scandinavians make stockfish and the Arabs dried dates.
All foods include water—cabbage and other leaf vegetables contains as much as 93% water, potatoes and other root vegetables 80%, lean meat 75% and fish, anything from 80% to 60%, depending on how fatty it is. If this water is removed, the activity of the bacteria(细菌)which cause food to go bad is checked.
Fruit is sun-dried in Asia Minor, Greece, Spain and other Mediterranean countries, and also in California, South Africa and Australia. Various methods are used, but in general, the fruit is spread out on trays in drying yards in the hot sun.
Nowadays most foods are dried mechanically. The method of such dehydration(脱水)is to put food in chambers through which hot air is blown at temperatures of about 110℃ at entry to about 43℃ at exit. This is the usual method for drying such things as vegetables, minced(切碎的)meat, and fish.
Dried foods take up less room and weigh less than the same food packed in cans or frozen, and they do not need to be stored in special conditions. For these reasons they are invaluable to the climbers, explorers and soldiers in battle, who have little storage space. They are also popular with housewives because it takes so little time to cook them. Usually it is just a case of replacing the dried-out moisture with boiling water.According to the text, the open-air method of drying food .
| A．is the one most commonly used today |
| B．was invented by the American Indians |
| C．has been known for hundreds of years |
| D．tends to be unhealthy |
Bacteria which cause food to go bad .
| A．cannot live in sunlight |
| B．are killed by drying |
| C．are in no way dependent on the water contained |
| D．have their activity greatly reduced by drying |
Today vegetables are most commonly dried .
| A．on hot and sunny days | B．in hot-air chambers |
| C．in the sun and wind | D．using the open tray method |
Housewives like dried foods because they .
| A．are quick to prepare |
| B．taste better than fresh foods |
| C．can be packed in a case |
| D．look fresh when cooked |
