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.

Renewable Energy Sources
Today petroleum provides around 40%of the world's energy needs,mostly fuelling automobiles .Coal is still used,mostly in power stations,to cover one-quarter of our energy needs,but it is the least efficient,unhealthiest and most environmentally damaging fossil fuel.Natural gas reserves could plug some of the gap from oil,but reserves of that will not last into the 22nd century either.
Most experts predict we will exhaust easily accessible reserves within 50 years.We could fasi reach an energy crisis.We need to rapidly develop sustainable solutions to fuel our future.Lesspolluting renewable energy sources offer a more practical long-term energy solution.They may benefit the world's poor too."Renewable"refers to the fact that these resources are not used faster than they can be replaced.
The Chinese and Romans used watermills over 2,000 years ago. But the first hydroelectric dam was built in England in 1870.Hydroelectric power is now the most common form of renewable energy,supplying around 20%of world electricity. China's Three Gorges Dam,which has just been completed,is the largest ever. At five times the size of the US's Hoover Dam,its 26 turbines will generate the equivalent energy of 1 8 coal-fired power stations.It will satisfy 3%of China's entire electricity demand.Surprisingly,some argue that hydroelectric dams significantly contribute green- house gases.
In 2003,the first commercial power station to harness tidal currents in the open sea opened in Norway .It is designed like windmill,but others take the form of turbines.
As prices fall,wind power has become the fastest growing type of electricity generation-quadrupling worldwide between 1999 and 2005 .Modern wind farms consist of turbines that gener- ate electricity.Though it will be more expensive,there is more than enough wind to provide the world's entire energy needs. Wind farms come in onshore and offshore forms.They can often end up at spots of natural beauty,and are often unpopular with residents.And turbines are not totally benignthey can interfere with radar and leave a significant ecological footprint,altering climate and killing sea birds.Migrating birds may have more luck avoiding them.Scotland is building
Europe's largest wind farm,which will power 200,000 homes.The UK's goal is to generate one- fifth of power from renewable sources,mainly wind,by 2020 .But this may cause problems,be- cause wind is unreliable.

A.There is plenty of wind to provide the world's entire energy needs.
B.It is the most rapidly growing type of electricity production.
C.It may not he reliable.
D.All of the above.
