For many years scientists have said that the earth is getting warmer. Now they have found something new-hot cities! In the southern US, they have found that cities become very hot in summer. For example, the city of Atlanta in Georgia has roof(屋顶) temperature of up to 50oC while it is 27℃ in the streets! At night, the outside of buildings stays so hot that the heat of the city causes storms over the city!
China also has the same kind of problems. Every year more farmland is used for factories or offices. More housing is needed, too. As people become richer, they buy more cars. New roads are needed and new car parks are built in the city centers. This all makes cities hotter.
It isn’t easy to change the situation. City planners say that we should plant more trees in the middle of cities. Every new street should have trees on both sides, they say. Trees make the temperature lower, so we should have more trees in our parks and squares. We should also paint our roofs white. If we do this, they do not become so hot. Every roof in a hot and sunny country should have solar(太阳的) roof panels. The electricity from these can be used to run the air conditioners (空调)in the buildings.
People continue to cut down forests around the cities. This makes the problem worse. Cities are growing faster and faster. By the year 2025, four fifths(五分之四) of the population will be living in cities. If we go on like this, there will not be enough farmland to feed everyone in the world

A.Cities won’t grow very fast
B.We will not have enough food
C.Most people will move to the countryside
D.People will plant more trees outside the cities

Biodiversity(生物多样性), or biological diversity, is a wide-ranging concept that covers all the different kinds of plant and animal species present on earth. Environmentalists believe that many millions of species exist. As all these living organisms are dependent on each other in some way, biodiversity is desirable. Any loss to the planet is actually a loss for mankind as well, and it is our responsibility to try and save Earth’s biodiversity.
Biodiversity has a vital role to play in the evolution(演变)of species. Species become extinct, but new species evolve, and this is how a balance is maintained. This may sound pretty simple, but it takes millions of years for changes to take place.
Biodiversity is also very important to the stability of food webs. Damage to them can mean disaster for an entire ecosystem. The extinction of a single animal species can put huge pressure on the numerous other species dependent on it.
Biodiversity also has an important role to play in human society. Apart from being the most intelligent species on earth, human beings are also the most dependent. We depend on nature to meet our basic needs. When we change the balance of nature to create our cities and bring about our technical advances, we knowing or unknowing cause great damage to the ecosystem. This must be understood, and the damages must be reversed(颠倒)in any way they can to ensure that the balance of the ecosystem is maintained.
小题1:We learn from the first paragraph that_________.
A biodiversity can be seen
B all living species are found on earth.
C people everywhere are aware of the importance of biodiversity
D the loss of any species can affect humans
小题2:Why can change in food webs lead to disaster?
A Because it can make people suffer from disease
B Because it can put huge pressure on some species
C Because it takes a long time for such changes to take place
D Because it will damage ninety-nine percent of species
小题3:What does the underlined word probably mean?
A 画线  B Peace  C Strength  D Variety
小题4:We learn from the last paragraph that __________.
A humans are as independent as they are intelligent
B the balance of the ecosystem is easily maintained
C nature has given us a lot
D nature is taking revenge on us
小题5:Which of the following may be the best title for this passage?
A Food Webs are Closely Related to Biodiversity.
B Biodiversity Plays a Very Important Role in Evolution
C How Biodiversity Affects Human Society.
D Understanding Biodiversity and Its Importance.
What’s your dream vacation? Watching wildlife in Kenya? Boating down the Amazon? Sunbathing in Malaysia? New chances are opening up all the time to visit the world. So we visit travel companies, compare prices, and pay our money.
We know what our vacation costs us. But do we know what it might cost someone else? It’s true that many poorer countries now depend on tourism for foreign income. Unfortunately, though, tourism often harms the local(本地的) people more than it helps them.
It might cost their homes and lands. In Myanmar, 5,200 people were forced to leave their homes among the pagodas(佛塔) in Bagan so that tourists could visit the pagodas.
Tourism might also cost the local people their jobs and dignity(尊严). Local workers often find only low-paying jobs in the tourist industry. And most of the money do not help the local economy(经济). Instead, money return to the tour operators in richer countries, When the Maasai people in Tanzania were driven from their lands, some moved to poor places of the city. Others now make a little money selling things or acting for photos.
Problems like these were noticed more than 20 years ago. But now tour operators and local governments are working together to begin correcting them. Tourists, too, are putting on the pressure.     
The result is “ethical(合乎职业道德的)tourism”. Ethical tourism has people at its heart. New international agreements and rules can help protect the people’s lands, homes, economies and cultures. The beginnings are small, though, and the problems are complex(复杂的).
But take heart. The good news is that everyone, including us, can play a part to help the local people in the places we visit. Tour operators and companies can help by making sure that local people work in good conditions and earn the money they should get.
They can make it a point to use only locally owned hotel, restaurants and guide services. They can share some money to help the local economy. And they can help the local people plan and manage tourism.
What can tourists do? First, we can ask tour companies to provide information about the conditions of local people. We can then make our choices and tell them why. And while we’re abroad, we can:
Buy local foods and products.
Pay a fair price for goods and services and not bargain for the cheapest price.
Ask before taking photographs of people.
They are not just part of the scenery!
Let’s enjoy our vacation and make sure others do, too.
小题1:Which of the following is not mentioned?
A.Local people protected the pagodas in Bagan well.
B.Tourists may stay in hotels opened by local people.
C.Local people are mainly provided with low-paying work.
D.Tourists had better not bargain with local people for a cheap price.
小题2: The underlined phrase "take heart" means"      ".
A.pay attentionB.take careC.cheer upD.give up
小题3: According to the passage, the writer thinks          .
A.tourism is not a promising industry
B.dream vacations should be spent abroad
C.the problems caused by tourism are easy to settle
D.tourists should respect local customs and cultures
小题4:What is probably the best title for the passage?
A.Tourism Causes Bad Effects.B.Tourism Calls for Good Behavior.
C.Vacations Bring a Lot of Fun.D.Vacations Cost More Than You Think.
