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 |
Jane Austen, a famous English writer, was born at Steventon, Hampshire, on December 16,1775, and died on July 18, 1817. She began writing early in life, although the prejudices (偏见) of her times forced her to have her books published anonymously (匿名 ).
But Jane Austen is perhaps the best known and best loved of Bath’s many famous local people and visitors. She paid two long visits here during the last five years of the eighteenth century and from 1801 to 1806, Bath was her home. Her deep knowledge of the city is fully seen in two of her novels, Northanger Abbey and Persuasion, which are largely set in Bath. The city is still very much as Jane Austen knew it, basically keeping its streets and public buildings in the original shape, just like what she described in her novels. Now the pleasure of learning Jane Austen’s Bath can be enhanced (增强)by visiting the Jane Austen Centre in Gay Street. Here, in a Georgian town house in the heart of the city, you can find out more about Bath in Jane Austen’s time and the importance of Bath in her life and work.
The Centre has been set up with the help and guidance of members of the Jane Austen Society. After your visit to the Centre, you can look round the attractive shop, which offers a huge collection of Jane Austen related books, cards and many specially designed gifts.

Food sometimes gets poisoned with harmful things. A person who eats such food can get an illness called food poisoning. Food poisoning is usually not serious, but some types are deadly, The symptoms ( 症状) of food poisoning usually begin within hours of eating the poisoned food. Fever is one of the most common symptoms.
Certain microorganisms (微生物) cause most types of food poisoning. Bacteria and other microorganisms can poison eggs, meat, vegetables, and many other foods. After entering the body, these tiny living things release (释放) poisons that make people sick.
Some chemicals can also cause food poisoning. They are often added to food while it is being grown, processed, or prepared. For example, many farmers spray chemicals on crops to kill weeds and insects. Some people may have a bad reaction to those chemicals when they eat the crops.
Some plants and animals contain natural poisons that are harmful to people. These include certain kinds of seafood, grains, nuts, seeds, beans, and mushrooms.
When people handle food properly, the risk of food poisoning is very small. Microorganisms multiply rapidly in dirty places and in warm temperatures. This means that people should never touch food with ditty hands or put food on unwashed surfaces. Food should be kept in a refrigerator to stop microorganisms from growing. Meat needs to be co
oked thoroughly to kill any dangerous microorganisms. People should also wash foo
d covered with chemicals before eating it. Finally, people should not eat wild mushrooms or other foods that grow in the wild. Some of these foods may contain natural materials that are poisonous to humans. In addition, some types of fish can be poisonous.
Most people recover from food poisoning after a few days of resting and drinking extra water.
If people eat natural poisons, they must go to the hospital right away to have their stomachs emptied. Which of the following statements is NOT true?
| A．Food poisoning means death |
| B．When poisoned, food can make people sick |

People in the United 
States honour their
parents with two special days: Mother’s Day, on the second Sunday in May, and Father’s Day, on the third Sunday in June.These days are set aside to show love and respect for parents. They raise their children and educate them to be responsible citizens. They give love and care.
These two days make us think about the changing roles of mothers and fathers. More mothers are now working outside home. More fathers must help with the children care.
These two special days are celebrated in many different ways. On Mother’s Day, people wear carnations. A red one symbolizes a living mother, while a black one shows the mother is dead. Many people attend religious services to honour parents. It is also a day when people whose parents are dead visit cemetery ( 墓地). On these days, families get together at home, as well as in restaurants. They often have outdoor barbecues for Father’s Day. These are days of fun and good feelings and memories.
Another tradition is to give cards and gifts. Children make them in school. Many people make their own presents. These are valued more than the ones bought in stores. It is not the value of the gift that is important, but it is the thought that counts. Greeting card stores, florists, candy makers, bakeries, telephone companies and other stores do a lot of business during these holidays.Which of the following is NOT a reason for parents show love and respect for parents?
| A．Parents bring up children |

Dear Mom and Dad,
I'm afraid I have some very bad news for you. I have been very naughty and the school master is very angry with me. She is going to write to you. You must come and take me away from here. She does not want me in the school any longer. The trouble started last night when I was smoking a cigarette in bed. As I was smoking, I heard footsteps coming towards the room .I did not want a teacher to catch me smoking, so I threw the cigarette away. Unfortunately, the cigarette fell into the waste-paper basket. It caught fire.
There was a curtain near the waste-paper basket. It caught fire too. Soon the whole room was burning. The master phoned the fire brigade. The school is a long way from the town and before the fire brigade arrived, the whole school was on fire. The master said that the fire was all my fault and I must pay for the damage. She will send you a bill for about a million dollars.
I'm very sorry for this.
Much love

When it comes to eating out, we can't help thinking of big meals in the restaurants, which usually contain much more fat and less fibers. Whether it is a business meeting over lunch or a fast food meal with the kids, eating out is a part of our lives. We eat out to save a lot of time, like grabbing a bite at fast food restaurants, or we take dining out as a favorite way to relax and socialize with friends.
Eating out can be fun but many people still like eating at home more because it is healthier. When my dear wife does not prepare foods for me, I would rather cook some instant noodles and eat at home! However, we go out to eat once in a while for holidays or on special occasions.
More and more people want to make healthy food choices nowadays. Some are watching calories, while others want to keep their cholesterol(胆固醇)under control or eat less fat. Plan ahead and choose wisely, you will find foods that fit into your meal plan and make eating out both healthy and enjoyable.
Here are some pointers to remember that can help you make wise choices when eating out: go for balance, watch portion sizes and drink water or low-fat milk. Keep the ground rules of good nutrition in mind. Eat a variety of foods in moderate(适中的)amounts, limit the amount of fat you eat, and watch the amount of salt in food. If you develop the skills to make healthy choices now, your body will thank you later.
Eating out can be one of life's great pleasures. Make the right choices, ask for what you need, and balance your meals out with healthy meals at home. You can enjoy yourself and take good care of yourself at the same time. From the passage, we can infer that often eating out______________ .
