What would you think if someone suggested knocking down St Paul’s cathedral to widen the road,or pulling down Big Ben to make way for a car park? It’d be ridiculous,right? But when it comes to devastation(毁灭)of the natural world,we aren’t so easily shocked.But we should be...or we’ll be in a lot of trouble!

Nature is shrinking by the day.Ancient forests are destroyed.Wetlands are becoming dry.Woodland is disappearing,all in the name of progress.This is bad in itself,but it’s devastating for biodiversity.

Biodiversity refers to the variety of plants,animals and other living things which are all inter-connected.The ecological services provided by biodiversity are vital to everyday life.The air we breathe is a product of photosynthesis(光合作用)by green plants.In fact,all life on earth exists thanks to the benefit of biodiversity.More than 90 percent of the calories consumed by people worldwide are produced from 80 plant species.And 30 percent of medicines are developed from plants and animals.Maintaining a wide diversity of species in each ecosystem is necessary to preserve all living things.

The loss of biodiversity could be devastating.“It is wrong to think that biodiversity can be reduced indefinitely without threatening humans,” said Harvard University biologist Edward O Wilson,known as “the father of biodiversity”.He warned,“We are about to reach a critical point beyond which biodiversity loss will be unavoidable.”

But what can we do? The problem is that the concept of biodiversity is so vague.People might care about giant pandas,but it is much harder to excite them about the fate of tiny sea creatures which are being boiled to death in the cooling systems of power stations along coastlines.The Guardian newspaper is trying to help.It has started the Biodiversity 100 campaign to try to convince governments around the world to take action to deal with the widespread concerns about biodiversity.This includes persuading the UK government to create a series of marine reserves to change the decrease in the sea-life caused by industrial fishing,stopping fishing sharks by the Japanese fishermen and banning the killing of dingoes in Australia,among many other things.

There is a lot to do.And we’d better act quickly if we don’t want to end up with a planet that can’t support life!

One day I was in the back yard teaching my little nephew how to play football. He said that play football was something easier. His words immediately bring back memories of my childhood. As a little boy, I told my uncle I wanted to become football star like him. However, he taught me how to kick the ball. After some practice, I told him it was hardly for me to kick the ball the way he kicked them. He talked to me about not giving up on how I really wanted to do. Thank to his guidance and encouragement, and I’ve become a football star in my school.

Many kids help out around the house with chores(家庭杂务), such as sweeping the floor, emptying the dishwasher, taking out the trash and so on. 【1】

Paying kids for chores is one of the most hotly debated parenting topics, especially at a time where everyone is more concerned about their finances. The logic behind tying allowances to chores is clear. 【2】 So they should pay kids to do their jobs.

【3】 Susie Walton, a parenting educator and family coach, believes that by rewarding kids, parents are sending a message that work isn’t worth doing unless you get something in return. “Running any kind of household is a team effort.” Susie said. “A home is a living space for everyone in the family. It’s important for kids to see that we all have responsibilities in the house, and that families decide together how they want their home to look, and how they are going to keep it looking like everyone wants it to look.”

【4】 They believe that getting a cash allowance or other rewards motivates kids to do chores, and it also teaches them real world lessons about how we need to work to earn money. “Our goal is to encourage kids to earn rewards,” says Chris Bergman, founder of Chore Monster. “ 【5】 ”

A. Many people hold the view.

B. In exchange, they get some pocket money or other rewards.

C. Other people think differently.

D. But some people do not think that kids should get rewards for doing chores.

E. Grown-ups get paid to do their jobs.

F. Kids need positive reinforcement（强化）to help motivate them.

G. Pay kids is sending a bad message.

The kings of ancient Egypt planned strong tombs to keep their bodies safe after death and to hold their treasure.The Great Pyramids along the Nile are on its west bank.The ancient Egyptians compared the rising of the sun to the beginning of life and the setting of the sun to the end of life.This is why their dead bodies were buried on the west bank of the Nile.

The people of Mexico also built pyramids.They did not build the pyramids for tombs.They used to build a pyramid and then a temple on top of it.The pyramids of Mexico are not as high as the pyramids of Egypt,but they are bigger.Each of the pyramids has a wide stairway(楼梯) that goes from the bottom to the top.

The biggest pyramid in Mexico is almost 2,000 years old.Scientists think it took 10,000 men more than ten years to build it.On the top they built a temple of the sun.The temple is no longer there,but people still call it the Pyramid of the Sun.Near it is another huge pyramid,the Pyramid of the Moon.

Researchers are placing robotic dogs in the homes of lonely old people to determine whether they can improve the quality of life for humans.Alan Beck,an expert in human-animal relationship,and Nancy Edwards,a professor of nursing,are leading the animal-assisted study concerning the influence of robotic dogs on old people’s depression,physical activity,and life satisfaction.“No one will argue that an older person is better off being more active,challenged,or stimulated(刺激),” Edwards points out.“The problem is how we promote that,especially for those without friends or help.A robotic dog could be a solution.”

In the study,the robot,called AIBO,is placed for six weeks in the homes of some old people who live alone.Before placing AIBO in the home,researchers will collect baseline data for six weeks.These old people will keep a diary to note their feelings and activities before and after AIBO.Then,the researchers will review the data to determine if it has inspired any changes in the life of its owner.

“I talk to him all the time,and he responds to my voice,”says a seventy-year-old lady.“When I’m watching TV,he’ll stay in my arms until he wants down.He has a mind of his own.”

The AIBOs respond to certain orders.The researchers say they have some advantages over live dogs,especially for old people.Often the elderly are disabled and cannot care for an animal by walking it or playing with it.A robotic dog removes exercise and feeding concerns.

“At the beginning,it was believed that no one would relate to the robotic dog because it was metal and not furry,” Beck says.“But it’s amazing how quickly we have given up that belief.”

“Hopefully,down the road,these robotic pets could become more valuable health helpers.They will record their masters’ blood pressure,oxygen levels,or heart rhythms.AIBOs may even one day have games that can help stimulate older people’s minds.”

【1】The purpose of Beck and Edwards’ study is to .

A.understand human-animal relationship

B.find the causes of old people’s loneliness

C.make lonely old people’s life better

D.promote the animal-assisted research

【2】In the research,the old people are asked to .

A.note the activities of AIBOs

B.keep AIBOs at home for 12 weeks

C.analyze the collected information

D.record their feelings and activities

【3】What is the advantage of AIBOs over live dogs?

A.They can watch TV with their owners.

B.They can help the disabled people.

C.They respond to all the human orders.

D.They are easier to keep at home.

【4】The author seems to suggest that the future robotic dogs may .

A.keep old people active

B.cure certain diseases

C.change people’s beliefs

D.look more like real dogs

Backpacking in Europe is a wonderful experience for young people around the world.After high school or university,you can plan a European backpacking trip.

Packing

As you plan the things you will carry,bring warm clothes and a raincoat or umbrella to deal with changing weather in different European countries.Europeans like dressing nicely,and good clothes will make you feel less like a dusty(满是灰尘的) backpacker.It is not worth taking the trouble to bring a hair dryer or shampoo,as you can buy basic necessities(必需品) in Europe.

Hostels

The cheapest places to sleep when backpacking in Europe are hostels(where people can stay and eat fairly cheaply).Most hostels have a lot of information about low-cost ways to see local attractions,and many offer tours.The cost for hostel beds differs from country to country.In Paris,you might pay 30 euros,but in Bulgaria,you can get a bed for 10 euros.In general,hostels are more expensive in large,popular cities such as Paris,Rome and London.

Many backpackers use rail passes(火车通票),which allow unlimited(不受限的) travel within country groups over a period of time.If you have the time to travel by train and will be traveling in a country group,this can be a good deal.Otherwise,you may consider point-to-point tickets,local trains,buses and airlines such as Ryanair,easyJet and Wizz Air,which offer cheap flights.

Food

Eating out in Europe can come with a high cost,and the best way to cut your food budget(预算) is to cook meals in the shared kitchens in hostels.You can make several meals into picnics to take advantage of Europe’s parks.When shopping for your picnic,try and buy at a local market.You save some euros while supporting the local industry at the same time.When eating out,choose restaurants away from tourist attractions.

【1】Which of the following is an advantage of hostels?

A.They are often built in popular cities.

B.They are mainly open to young people.

C.They usually provide tour information.

D.They always ask the same price for their beds.

A.Traveling. B.Shopping.

C.Entertainment. D.Transportation.

【3】To make a cheap trip in Europe,you’d better .

【题目】A rising population is one of the main reasons that there is global warming. Between 1650 and 1850 the population increased by 0.75 billion people going from 0.25 billion to one billion. From 1930 to the end of the century the population rose from two billion to over six billion. In just a third of the time the population rose by more than five times what it did before. It is expected that this trend in the changing population will continue and could even heighten. The growing population requires increasing amounts of energy. These energy demands and other supplies require production, which almost always involves the emission of greenhouse gases. The more the population increases the more greenhouse gases that are produced and the greater the increase in temperature.

The burning of fossil fuels is one of the best-known causes for global warming. The major reason for fossil fuels contributing so much to global warming is the release of carbon that occurs during the burning of fossil fuels. When people burn fossil fuels, they release large amounts of carbon by way of the release of carbon dioxide. The carbon dioxide in the air then leads to global warming.

Another source of carbon dioxide comes from deforestation. In forests there is a large amount of carbon that is stored in the trees and other plants. This carbon is out of the atmosphere because the trees consume the carbon from carbon dioxide. When people cut down trees, they are frequently burned. This burning releases the carbon dioxide into the atmosphere that was stored in organic matter. Even when new trees are planted, it can take up to one hundred years to make up for the carbon that was released. It is commonly thought that because trees absorb more carbon dioxide, the atmosphere experiences positive effects.

Sophie Armstrong, the writer of Earth Care put it, “There’s no doubt that the earth is becoming warmer because of human activity rather than a random but natural phenomenon.

【1】Which of the following titles goes with the text?

A. A Rising Population

B. Saving Sources of Energy

C. Global warming: The causes

D. Carbon Dioxide

【2】The underlined word “deforestation” means________ .

A. rising population B. burning of fossil fuels

C. greenhouse gas D. cutting down or burning trees.

【3】To sum up from the passage, it is_________ that has caused global warming.

A. human activity B. sources of energy

C. natural forces D. the polluted atmosphere

【4】Which column of a website might the passage come from?

A. Economy. B. Art C. Environment D. Health
