Dan Bebber is a senior research fellow at the University of Exeter in Britain. He says research has shown that wild plants and animals are moving toward Earth's North and South poles as the planet warms.
Mr Bebber wanted to know if the same thing was happening with organisms that attack agricultural crops. He examined reports of first sightings of new insects and diseases around the world. The records came from CABI - the Centre for Agricultural Bioscience International. He says the group began collecting information from developing and industrialized countries years ago.
Dan Bebber and his research team studied 612 different organisms - from viruses and bacteria to insects like beetles and butterflies. They found that since 1960, crop pests and diseases have been moving toward the poles at an average rate of about 3 kilometers each year. Mr Bebber says this puts the most productive farmland in the world in danger.
"As new species of pests and diseases evolve and potentially the environment for them becomes more amenable at higher latitudes, the pressure on the breadbaskets of the world is going to increase."
Farmers face other threats. Invasive species passed through trade are also causing problems. Gene Kritsky is an Entomologist at the College of Mount St. Joseph in Ohio. He specialises in the study of insects. He says climate change may improve conditions for some invasive species.
“It means that species in other parts of the world that might do well in warmer temperatures can now do well in the breadbasket of America.”
Another Entomologist Christian Krupke of Purdue University says the effects of these changes will depend very much on the crop, the insect and the disease. But he says the research is a warning sign that people should care about climate change and do something about it.The purpose of Dan Bebber’s research was to find ______.
A.if farmland could be moved to colder places thanks to global warming |
B.if diseases and insects harmful to crops were going towards colder areas |
C.if organisms were moving to the north and south poles |
D.if the number of crop pests was increasing |
According to Dan Bebber, if crop pests keep moving towards the poles, ______.
A.it will be hard for farmers to kill them |
B.the most productive farmland will produce more crops |
C.the earth will not produce enough food to support the world |
D.the conditions for some crops may be improved |
Which of the following is not a threat that farmers have to face?
A.Climate change helps crop pests to adapt to new environment. |
B.Foreign species are brought in by trade. |
C.Invasive species doing well in warmer places might do well in America. |
D.The impacts of the climate and species changes on crops are not easy to determine. |
The underlined word “amenable” in the fourth paragraph most probably means ______.
A.agreeable | B.terrible | C.unfriendly | D.changeable |
My mother loves flowers. As soon as warm weather comes around, you will find her planting, watering and weeding over everything .For many years we lived next door to each other, and she spent as much time in my garden as she did her own. After the flowers became plentiful each summer, she would cut colorful bouquets(花束)to enjoy inside the house—both hers and mine . I would often come home from work and find a beautiful arrangement(布置)of fresh flowers on my coffee table.
Shortly before Christmas one year, a local flower shop offered a bouquet-a-month special. It seemed to be a great way to thank her for all of the flowers she had given me through the years.
After the holidays, in early January, I drove her to the flower shop to pick up her first month’s bouquet. the small fresh colorful bouquet would hardly fill a small vase(花瓶).
I was so embarrassed(尴尬的).However, after we returned home, she began to arrange the flowers she had received.“Mom, I’m sorry, ”I told her.“I can’t believe how skimpy that bouquet is.”She looked at me and smiled.“It’s okay,”she said“It allows me to better enjoy the beauty of each one.”
Mom’s words helped me to realize something bigger and more important—when we have too many good things, we often fail to enjoy the beauty of each one.

Thousands of taxi drivers in Shenyang, Liaoning province, reportedly blocked streets with their vehicles on Sunday in protest against unlicensed vehicles using taxi-hiring apps(打车软件) and apps-based car rental companies providing passenger services, including high-end cars. Although the drivers also complained about the withdrawal of the fuel subsidy by the government, their main complaint was the loss of business because of the rising number of Internet-based car services companies.
On Wednesday, news reports came that Beijing transport authorities will take measures to stop the illegal “taxi business” of private cars through the newly rising Internet apps, following the footsteps of Shenyang and Nanjing.
It is not yet clear how the Shenyang city government will handle the issue and whether it will declare the services offered by market leaders such as Didi Dache, a taxi-hiring app provider backed by Tencent Holdings, and Kuaidi Dache illegal. But Shanghai transport regulators have set a rule, by banning Didi Zhuanche, or car services offered by Didi Dache in December.
Such regulations will cause a setback to the car-hiring companies and investors that are waiting to cash in on the potentially booming business. Just last month, Didi Dache got $700 million in funding from global investors, including Singapore state investment company Temasek Holdings, Russian investment company DST Global and Tencent. Besides, the market is uncertain that Kuaidi Dache is about to finalize its latest round of funding after getting $800 million from global investors.
Regulatory uncertainties, however, could cast a shadow on the future of the Internet-based car-hiring services, which have become popular in most of China’s big cities. To be fair, these companies’ business model is anything but bad. For example, Didi Zhuanche works side by side with established car rental companies to provide high-end car service mainly for businesspeople through the Internet and mobile phone apps.
Every link in this business model chain has legal companies and services. Hence, it is hard to define it as illegal and ban it.Why did taxi drivers in Shenyang block the streets with their vehicles?
A.Because they wanted the government to increase their driving allowances. |
B.Because they wanted to be educated how to use the taxi-hiring apps. |
C.Because they wanted to make their main complaints known to the government. |
D.Because they wanted to call on passengers not to hire the private cars. |
The author’s attitude to banning internet car-hiring service is______.
A.positive | B.negative | C.neutral | D.unclear |
Which of the following statements is false according to the passage?
A.The problem referred to in the passage exists in all cities |
B.App-based car rental is helpful to some degree |
C.The government should regulate the app-based car rental market |
D.Didi Dache is a China-foreign joint company |
From the passage we learn ___________.
A.Shenyang banned apps-based car rental companies |
B.Shanghai is the second city banning Didi Zhuanche |
C.some international investment companies have faith in the future of apps-based car rental companies |
D.it is easy to describe the apps-based car rental companies illegal |
Jacqueline Bouvier Kennedy Onassis was one of the most private women in the world, yet when she went to work as an editor in the last two decades of her life, she revealed(展现)herself as she did nowhere else.
After the death of her second husband, Greek shipping magnate(巨头)Aristotle Onassis, Jacqueline’s close friend and former White House social secretary Letitia Baldrige made a suggestion that she consider a career in publishing. After consideration, Jacqueline accepted it. Perhaps she hoped to find there some idea about how to live her own life. She became not less but more interested in reading. For the last 20 years of her life, Jacqueline worked as a publisher’s editor, first at Viking, then at Doubleday, pursuing(追求)a late-life career longer than her two marriages combined. During her time in publishing, she was responsible for managing and editing more than 100 successfully marketed books. Among the first books were In the Russian Style and Inventive Paris Clothes. She also succeeded in persuading TV hosts Bill Moyer’s and Jose Campbell to transform their popular television conversations into a book, The Power of Myth. The book went on to become an international best-seller. She dealt, too, with Michael Jackson as he prepared his autobiography(自传), Moonwalk.
Jacqueline may have been hired for name and for her social relations, but she soon proved her worth. Her choices, suggestions and widespread social relations were of benefit both to the publishing firms and to Jacqueline herself. In the books she selected for publication, she built on a lifetime of spending time by herself as a reader and left a record of the growth of her mind. Her books are the autobiography she never wrote. Her role as First Lady, in the end, was overshadowed by her performance as an editor. However, few knew that she had achieved so much.We can learn from the passage that Jacqueline _________

Alice’s mother died when Alice was five years old. Alice, who grew up to be my mother, told me that after her mother’s death her family was too poor to even afford to give her a doll.
In December 2012, I had a job at a local bank. One afternoon, we were decorating the tree in the bank lobby(大厅). One of my customers approached me with her beautiful handmade dolls. I decided to get one for my daughter, Katie, who was almost five years old. Then I had an idea. I asked my customer if she could make me a special doll for my mother—one with gray hair and spectacles(眼镜): a grandmother doll. And she gladly agreed.
A friend had told me that his dad who played Santa Claus would be willing to make a visit on Christmas morning to our home to deliver my Katie her presents, so I made some special arrangements.
Christmas Day arrived and at the planned time; so did Santa Claus. Katie was surprised that Santa had come to see her at her own house. As Santa turned to leave, he looked once more into his bag and found one more gift. As he asked who Alice was, my mother, surprised at her name being called, indicated that she in fact was Alice. Santa handed her the gift, with a message card that read:
For Alice:
I was cleaning out my sleigh(雪橇) before my trip this year and came across this package that was supposed to be delivered on December 25,1953. The present inside has aged, but I felt that you might still wish to have it. Many apologies for the lateness of the gift.
Love,
Santa Claus
My mother’s reaction was one of the most deeply emotional scenes I have ever seen. She couldn’t speak but only held the doll she had waited fifty-nine years to receive as tears of joy ran down her cheeks. That doll, given by “Santa”, made my mother the happiest “child” that Christmas.【改编】Why couldn’t the writer’s mother have a doll when young ?_________.

【原创】In the " Mystery Spot" in California, you will be able to experience what it's like to live in a gravity-free world, without ever leaving the earth.
Discovered in 1939, the area where Mystery Spot is located was originally marked for a summer cabin. But when people tried to chart the plot, their instruments started going out of control. Investigators that were sent to look into the strange phenomenon reported feeling light-headed as though some invisible force was trying to knock them off balance. The decision to build the summer cabin was abandoned. Instead, the owners decided to build a structure that they called the Mystery Spot and open it to the public so that everyone could experience it.
Over the years, thousands of tourists have flooded to the 150-square-foot area to see short people appear the same height as tall ones and experience leaning at impossible angles without falling over.
So what causes these strange things to happen? Some believe that it is because the area is an electromagnetic(电磁的) hotspot, while others are convinced that there are some unknown geological forces at work to contradict the law of gravity.
Rational scientists have thrown cold water on all these theories. In 1981, Ray Hyman, a psychology professor, conducted a study on this and other similar mystery spots that have been " discovered" in various parts of the country. His conclusion? It's because of the way the structures have been constructed.
Though they appear to be normal structures, they are like funhouses, filled with floors that are not level, corners that are not squared and walls that are not vertical.
Some experts believe that mystery spots such as the one in Santa Cruz are a product of the Great Depression, when the only industry that was growing in America was entertainment.What can we do in the " Mystery Spot" in California?
A.To experience what it is like to have no gravity. ' |
B.To make preparations to leave the earth for space. |
C.To communicate with astronauts in space. |
D.To look for answers to many mysteries. |
What does the underlined word "it" refer to in Para. 2 ?
A.Charting a place with advanced instruments. |
B.Being made light-hearted and happy by some force. |
C.What it's like to have no gravity in a place. |
D.Seeing short people grow tall. |
What's the explanation of some rational scientists to the strange phenomenon?
A.The Mystery Spot is located in an electromagnetic hotspot. |
B.There are some unknown geological forces underground. |
C.The Mystery Spot is a normal structure like funhouses. |
D.The Mystery Spot was built in a special way, |
After the Mystery Spot was built, it _________.
A.has become a spot where hot movies are made |
B.has become a tourist attraction |
C.has been a place where short people always go |
