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 explore the world. So we visit travel agents, compare packages and 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 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 livelihood and dignity. Local workers often find only menial（卑微的）jobs in the tourist industry. And most of the profits do not help the local economy. Instead, profits return to the tour operators in wealthier countries. When the Maasai people in Tanzania were driven from their lands, some moved to city slums. Others now make a little money selling souvenirs or posing for photos.
Problems like these were observed more than 20 years ago. But now some non-government organizations, tour operators and local governments are working together to begin correcting them. Tourists, too, are putting on the pressure.
The result is responsible tourism, or“ethical tourism.”Ethical tourism has people at its heart. New international agreements and codes of conduct can help protect the people’s lands, homes, economies and cultures. The beginnings are small, though, and the problems are complex.
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 reasonable wages.
They can make it a point to use only locally owned hotels, restaurants and guide services. They can share profits fairly to help the local economy. And they can involve the local people in planning and managing tourism.
What can tourists do? First, we can ask tour companies to provide information about the conditions of local citizens. We can then make our choices and tell them why. And while we’re abroad, we can:
★Buy local foods and products, not imported ones.
★Pay a fair price for goods and services and not bargain for the cheapest price.
★Avoid flaunting(炫耀) wealth.
★Ask before taking photographs of people. They are not just part of the landscape! Let’s enjoy our vacation and make sure others do, too.
【小題1】.
．What is probably the best title for the article?

A．Tourism Causes Bad EffectsB．Tourism Calls for Good Behavior
C．Vacations Bring a Lot of FunD．Vacations Cost More Than You Think
【小題2】.
The underlined phrase“take heart”means“     ”.
A．pay attentionB．take careC．cheer upD．calm down
【小題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 culture

Deep in the Amazon forest, thousands of people still live in isolation from the rest of the world.
In a recent press release, the Brazilian government confirmed the existence of another isolated tribe of about 200 people living in the Vale do Javari reservation. The 200 people living in the Vale do Javari reservation. The reservation, located near the Peruvian border, is about the size of Portugal. At least another 14 isolated tribes, with a total population of about 2000, call the area home.
The newly observed group lives on four large straw-roofed buildings and grows corn, peanut and other crops.
Brazil’s National Indian Foundation (BNTF) first noticed the reservation in the forest using satellite maps, but it wasn’t until April that an airplane expedition was able to confirm the tribe’s existence. “The work of finding and protecting isolated groups is part of Brazilian public policy,” said the BNIF officer for Vale do Javari, Fabricio Amorim. “To confirm something like this takes years of hard work.”
BNIF estimates there are 68 isolated tribes living in the Amazon. The organization uses airplanes to avoid disturbing the tribes through personal contact, but that doesn’t mean others are so respectful of their right to privacy.
Illegal fishing, woodcutting and hunting bring people into the protected area. Oil exploration on the Peruvian side of the border is another threat. All kinds of criminals also invade the lands of the local groups, said Amorim. The outsiders can damage the land and influence the cultures of indigenous(土著的)peoples. They can also bring diseases which can wipe out the whole population that still lack even basic antibiotics(抗生素).
Brazil’s indigenous peoples won the legal right to their traditional lands in Brazil’s 1988 Constitution, which stated that all indigenous lands shall be divided and turned over to tribes within five years. Indigenous groups now control 11 percent of Brazil’s territory, including 22 percent of the Amazon.
Allowing indigenous groups the right homelands is not just a matter of human rights. The rest of the world can benefit from their knowledge. Mark Plotkin has spent years living with the people of the Amazon and learning from their traditional healers. In his lecture, he pointed out that many useful materials and knowledge, including numerous drugs, can be gained from listening to the indigenous groups of the Amazon. Besides this, they are also more effective at protecting the land, and less expensive, than hired rangers(護林人).
【小題1】The underlined word in the first paragraph probably means “a state of            ”.

A．separationB．interaction
C．satisfactionD．excitement
【小題2】From the passage we can learn that the tribes in the Amazon forest             .
A．only live on a reservation designated for them
B．prefer straw-roofed buildings to wooden ones
C．keep contact with the outside world through airplanes
D．have the legal right to the land they live on
【小題3】Which of the following is TRUE according to Amorim?
A．Privacy violation is common among the Amazon tribes.
B．The laws dividing the lands of the tribes are far from enough.
C．Modern civilization endangers the tribes and their cultures.
D．It is hard to make public policy to protect primitive tribes.
【小題4】The last paragraph is mainly about              .
A．the lost human rights of the indigenous peoples
B．the benefits of protecting the primitive tribes
C．the value of traditional healing
D．the indigenous peoples as guardians of the Amazon forest

         Scientists in the United States say plant life has increased on Earth in the past twenty years and that in every area of plant growth the increase is the result of weather conditions.

         Eight scientists from across the United States did the study. The space agency NASA and the Department of Energy paid for it. The findings were published in the magazine Science.

         The researchers spent one and a half years examining weather satellite information. The information was recorded from 1982 to 1999. That period was one of the warmest on record. Researchers found that rainfall generally increased during that time.

         The satellites measured the number of leaves on plants and the amount of sunlight taken in. The scientists used that information to estimate what is called net primary production. This is total amount of carbon stored in land plants.

         The scientists report a 6% increase in stored carbon since 1982. They say gains were high in equatorial areas, especially around the Amazon River in South America. The area alone had a 1% increase in the net primary production.

Ramakrishna Nemani of the University of Montana in Missoula headed the study. He says reduced cloud cover led to growth in Amazon area. He also says the lack of clouds allowed more sunlight to get through. More sunlight meant increases in photosynthesis(光合作用). That is the process by which plants use energy from sunlight to produce the chemicals they need to grow.

         Northern Canada, the north-central United States and northern Europe were second in increased plant growth. Ramakrishna Nemani says a rise in temperature helped plants there.

         All together, the report says 25% of areas of plant life on Earth experienced increases. But the scientists also note increase in the number of people on Earth and carbon dioxide levels in the atmosphere. Ranga Myneni of Boston University in Massachusetts, another study scientist says humans use about half the net primary production on Earth. And he notes that the world population grew by 36% during the period of time studied.

 

1.Which of the following is in charge of the study?

         A. The space agency NASA of the US.

         B. The Department of Energy of the US.

         C. Ramakrishna Nemani in Missoula.

         D. Ranga Myneni in Massachusetts.

2.What’s the main cause of the plant growth put forward by the study?

         A. Growth in population.

         B. Regional features.

         C. Seasonal variation.

         D. Weather conditions

3. Why do scientists believe that reduced cloud cover has led to the plant growth in           the Amazon area?

         A. Because plants could take in more sunlight.

         B. Because plants could get more rainfall.

         C. Because plants could enjoy cooler air.

         D. Because plants suffer less from natural disasters.

4. Which of the following descriptions about the years from 1982 to 1999 is TRUE?

         A. It was the warmest on record.

         B. Rainfall decreased little by little.

         C. World population grew by 25%.

         D. Stored carbon increased by 6%.
