As a young man,he spent much of his life exploring the beauty of the wilderness.He walked more than a thousand miles across the country,through fields and woods.John Muir liked writing about the places he visited,describing their beauty. Muir also wrote about problems.In order to create more farmland for sheep and cattle, rnany trees were being cut down.This made Muir unhappy and worried,because he knew that trees were important to forests and to the animals that lived in them.Muir believed that nature should be conserved instead of being changed by human beings.He wrote articles in magazines and newspapers to spread the word about conserving forests.Soon,others began to listen. Muir wrote letters to important people,such as President Theodore Roosevelt.The president admired Muir's love for nature.When Roosevelt came to visit Muir in California. Muir convinced the president to go camping with him for three nights under the trees so they could talk about conservation.Later,President Roosevelt set aside 148 million acres of land for national forests and established five national parks.National parks are large areas of land that are protected from development. This means that people cannot build homes or businesses there. One of these parks is Yosemite National Park,the area that is featured on the back of the California quarter. Though it has been almost one hundred years since John Muir died,people continue his work today.His work as a conservationist helped us to see the beauty of our natural world.John Muir made us understand the importance of protecting our earth and our resources---then,now,and for the future.

Q: Read the following article and answer the question. Article: A city without cars would be very strange , right ? But Venice is such a city . Venice is in the northeast of Italy. It wasn't built on land, like Beijing or Shanghai, but on more than 110 islands. Seawater is everywhere around the city. Even so, travel isn't that difficult. The waterways have always been the best way to get around. There are 117 waterways and more than 400 bridges that can guide you where you want to go. People in Venice move from place to place by boat. Water makes the city special, but it is also a big problem. Sometimes tourists will have such strange experiences . One moment they walk across the Rialto Bridge , and there's nothing special . But when they come back to the bridge an hour later , it's underwater and everyone is wearing rain shoes . Once, people used too much underground water. This made the city get lower little by little. Now the city has gone down by 23 centimeters. Another problem is the rising seawater. The temperature has risen over the years. This has made ice of the Arctic Ocean melt . Every year, high waters hit the city in autumn and winter. When a lot of water comes, more than half of the city is underwater. Scientists are trying different ways to stop the city from getting even lower. The Italian government has asked some of Italy's biggest companies to build the MOST project , which was planned to be built under the seawater to stop the rising water . Anyway , this project is helping solve the problem . Question: Venice has gone down by 23 centimeters because _ . Answer:

Read the following article and answer the question. Article: Our school doesn't have many parties, but this year Ms Cipriano said we could have one. The fourth grade wanted the theme to be "Under the Sea", but the fifth grade wanted it to be "Outer Space". After a long discussion, it was decided to be the former one. Everyone had to be on a team, and everyone had to help do something. My team was in charge of special effects. Gary came up with a great idea. He got two big, old fishing nets which were once used by his father when he went fishing on the sea. Gary, Jemma, and I used ropes to tie the nets to the ceiling of the dining hall, and it looked really great. Then we cut out fish shapes from colored paper and stuck _ on the nets. Everyone seemed to go to the party in one of three costumes: some kind of fish, a mermaid, or Neptune -- the "King of the Sea". The dining hall looked great. Jemma's father had put up colored lights for us. We were feeling proud of our work when the disaster happened. The nets fell down. We were all caught in the fish nets. We were laughing so hard that we couldn't stand up. We truly felt as if we were "under the sea". This wasn't the effect we imagined, but it was special! ,. Question: What does the passage mainly talk about? Answer:

- Gary is a clever boy.

input with options: Read the following article and answer the question. Article: Many hospitals have blood banks. In these banks, blood of all types is stored. When blood is needed, it is taken from the bank. Healthy people then give blood to the bank to replace the blood that is used. Blood can be kept in the fridge for about three weeks with a kind of chemical. When people lose much of their blood because of operations or accidents, they may need transfusions . Some people may need transfusions because of illness. Sometimes only a part of the blood is used for transfusions. Plasma , the liquid part of the blood , may be given alone. Transfusions of plasma are often given when people have been badly burned. When a person gets a transfusion, he gets blood of the same type as his. Or there may be a bad reaction . To make it safer, before a transfusion is given, the blood to be used must be tested with the blood of the person who is to receive it. This testing is called cross matching of the blood. Oswald Robertson, an American doctor, was the first one to give transfusions. He used blood that had been stored for some time to help wounded soldiers in 1918 in World War One. Question: Blood banks get blood from _ . Answer:
OPTIONS:
- healthy people
- operations
- accidents
- transfusions
output:
healthy people
