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

The crisis at the damaged Fukushima Dai-Ichi Nuclear Power Station in northern Japan has raised worries about radiation risks. We spoke Tuesday with Jonathan Links, an expert in radiation health sciences. He is a professor at the Johns Hopkins Bloomberg School of Public Health in Maryland.
Professor Links says workers within the nuclear plant are the only people at risk of extremely high doses of radiation.
JONATHAN LINKS: "Of course, we don't know what doses they've received, but the only persons at risk of acute radiation effects are the workers."
For other people, he says, there may be a long-term worry. People can get cancer from low doses of ionizing radiation, the kind released in a nuclear accident.
Professor Links says scientists can use computers to quickly model where radioactive material has blown and settled. Then they measure how large an area is contaminated. He says if the situation is serious enough, officials could take steps like telling people not to eat locally grown food or drink the water.
JONATHAN LINKS: "But that would only be the case if there was a significant release and, because of wind direction, the radioactive material was blown over the area, and then settled out of the air into and onto water, plants, fruits and vegetables."
The reactors at Fukushima are on the Pacific coast. But Professor Links says people should not worry about any radioactive material leaking into the ocean.
JONATHAN LINKS: "Even in a worst-case scenario accident, the sea provides a very high degree of dilution. So the concentration of radioactivity in the seawater would still be quite low."
Japan is the only country to have had atomic bombs dropped on it. That memory from World War Two would create a stronger "psychological sensitivity" to radiation exposure, Professors Links says.
Next month is the twenty-fifth anniversary of the explosion and fire that destroyed a reactor at Chernobyl in Ukraine. The nineteen eighty-six event was the world's worst accident in the nuclear power industry.
A new United Nations report says more than six thousand cases of thyroid cancer have been found. These are in people who were children in affected areas of Belarus, Russia and Ukraine. The report says that by two thousand five the cancers had resulted in fifteen deaths.
The cancers were largely caused by drinking contaminated milk. The milk came from cows that ate grass where radioactive material had fallen.

根據(jù)短文內(nèi)容，從短文后的七個(gè)選項(xiàng)中選出能填入空白處的最佳選項(xiàng)。選項(xiàng)中有兩項(xiàng)為多余選項(xiàng)。
A 7．0 magnitude（級(jí)）earthquake killed more than 230,000 people in Haiti．Then an 8．8 magnitude quake killed more than 900 people in Chile．And few weeks later, a 6．0 magnitude quake struck rural eastern Turkey, killing at least 57 people．
The earthquakes kept coming hard and fast． 【小題1】  It’s not．The problem is what’s happening above ground, not underground, experts say．
【小題2】  They’re rapidly putting up buildings that can’t stand up to earth quakes, scientists believe．
And news reports and better earthquake monitoring make it seem as if earth quakes are increasing all the time．
On average, there are 134 earthquakes a year that have a magnitude between 6．0 and 6．9．So far this year there have been 40 earthquakes—more than in most years for that time period．But that’s because the 8．8 quake in Chile caused a large number of strong aftershocks．
Also, it’s not the number of quakes, but their destructive effects that gain attention．The death is largely due to building standards,  【小題3】   Paul Earle, a US seismologist, called for better building standards in the world’s big cities．
Of the 130 cities worldwide with populations of more than I million, more than half are likely to be hit by earthquakes． 【小題4】 “If you have a problem feeding yourself, you’re not really going to worry about earthquakes,” said Paul．
The earthquakes made everyone start to think 【小題5】  “People are paying attention to the violent planet we’re always living on．Come back an another six months if there has been no earthquakes, most people will have forgotten it again,” said US disaster researcher Dennis Mileti．

A．But it won’t last．
B．More people are moving into big cities．
C．Earthquakes don’t kill people, buildings do．
D．There have been more deaths overt the past decade from earthquakes．
E．Many people began to wonder if something terrible is happening underground．
F．While it seems as if the are more earthquakes occurring, there really aren’t．
G．But developing nations with growing populations don’t pay attention to earthquake preparedness．
