Living History at Jamestown Settlement
A woman in Native American clothes is sitting in the sun,sewing a dress from skin.Inside a building,a colonist is making a wooden chair,using very simple tools.And all around,tourists are taking pictures with their digital（数码的）cameras. This is Jamestown settlement today.
Jamestown,Virginia,was one of the first place in the world where people from Europe, American,and Africa came together in 1608 .Today,it is a living history museum,where chil- dren and adults come to experience history. In a living history museum,actors wear clothes and adults form the past and demonstrate many of the activities of daily life back then.The actors also talk to the visitors and explain everything they do.
At a living history museum,there are always many things to touch,hear,and smell. Visitors at Jamestown settlement can walk through copies of the three small sailing ships that carried colo-nists to Virginia and even lie down in a colonist's bed!The colonists stayed on the crowed,dan-gerous ships for more than four months.When they got to Virginia,they built an area of houses with a high wall around it. In today's fort(堡垒）,you can see houses, a church, and even a gar-den with foods that the colonists ate.Women in long dresses work inside their homes,and visitors can help them with their sewing and cooking.
There is also an Indian Village at Jamestown settlement,and it books very different from the fort. It shows how the Indians lived in long houses and grew corn and other crops in large fields. Actors there make pottery（陶器）and teach visitors how to play Indian games. You can even help them make an India boat from a tree!
Today,the living history museum of Jamestown is very popular,especially with children and families.People come here to have fun,but also to learn. Many school classes visit to experience old ways of getting things done .A living history museum is the best way to understand how people lived in the past.

At a living history museum,visitors cannot touch any of the things on display.

The Cold Places

The Arctic is a polar region.It surrounds the North Pole.
Like Antarctica,the Arctic is a land of ice and snow. Antarctica holds the record for a low temperature reading一125 degrees Fahrenheit below zero.Reading of 85 degrees below zero is common in both the Arctic and Antarctica. Winter temperatures average 30 degrees below zero in the Arctic. At the South Pole the winter average is about 73 degrees below zero.
One thing alone makes it almost impossible for men to live in Antarctica and in parts of the Arctic.This one thing is the low temperature一the killing chill of far North and the polar South.
To survive,men must wear the warmest possible clothing. They must build windproof shelters. They must keep heaters going at all times.Not even for a moment can they be unprotected against the below-zero temperatures.
Men have a way of providing for themselves.Polar explorers wrap themselves in warm coats and furs.The cold makes life difficult. But the explorers can stay alive.
What about animals?Can they survive?Do we find plants?Do we find life in the Arctic and in Antarctica?Yes,we do.There is life in the oceans.There is life on land.
Antarctica,as we have seen,is a cold place indeed.But this has not always been the case. Expedition scientists have discovered that Antarctica has not always been a frozen continent. At one time the weather in Antarctica may have much like our own.
Explorers have discovered coal in Antarctica. This leads them to believe that Antarctica at one time was a land of swamps and forests.Heat and moisture must have kept the trees in the forests alive.

Despite the hostile environment,both animals and plants can be found in the oceans and on land in polar areas.
A:Right
B:Wrong
C:Not mentioned

Touring the Antarctic Brings Danger

1 Ship tourism to Antarctica is on the rise.More than 35,000 tourists are expected to visit Antarctica
this spring and summer. In 1992一1993,6,750 visited Antarctica,according to the Antarctic Treaty
Secretariat. All of this tourism,however,is posing great danger to both tourists and the environment.
2 Among the tourist ships that visit the continent,the Explorer,a Canadian ship,was one of the first.
Launched in 1969,it was built to ferry tourists to Antarctica.Last week,however,it became the first commer-
cial passenger ship to sink beneath the polar region's waters.Fortunately,all of the passengers and crew
members were evacuated（撤离）from the ship. However , the sunken ship threatens the Antarctic'S fragile
environment.The ship was estimated to be holding 48,000 gallons of marine diesel fuel.
3 The accident was not unanticipated.Both the US and the UK had warned at a conference of Antarc-
tic treaty nations in May that the tourism situation in the region was a potential disaster. The US said in a pa-
per,"People should take a hard look at tourism issues now,especially those related to vessel safety.""The
increasing number of ships operating in Antarctica means that ships are under greater pressures to meet the
time slots for visiting key sites,"the British government wrote in a paper at the meeting of treaty nations.
4 Although the Antarctic seas are relatively calm,floating ice poses a potential threat to ships.The
owner of the Explorer attributed the sinking to a fist-size hole in the hull created by ice.Many of the other
large cruise ships now visiting Antarctica have little or no ice reinforcement in their designs.Such ships
generally can only come to the continent at the height of summer. But the tourist rush is pushing vessels into
dangerous situations.
5 As a natural frontier,Antarctica is in a legal muddle.There are no obvious answers as to who is re-
sponsible for dealing with the threat that tourism may cause to human life and the environment.
6 Jim Barnes,executive director of the Antarctic and Southern Ocean Coalition,told the New York
Times,"There'S no military or coast guard for Antarctica."He asked,"Do we want this(the Antarctic)to
become Disneyland,or do we want some controls?"
