Read the following article and select the best answer. Article: Imagine life without the Internet -- not being able to chat with your friends or look up information for your homework or research project. That is the reality for nearly two-thirds of our world's population, either because they cannot afford WiFi access or are located in remote, inaccessible areas. Now Google has decided to do something about that. Google's Project Loon will attempt to send balloons high up into our earth's atmosphere in 2015. Each balloon will be equipped with a mini computer and a WiFi radio that will send Internet signals over the places it is floating over. The network equipment on Google balloons will communicate with a special antenna attached to each user's home. These antennae are in turn connected to a local Internet Service Provider. Each balloon will also communicate with each other to hand over signals as one floats out of an area, and another floats in. The balloons are 15 meters wide and made of a material that is three times thicker than the plastic bag at the supermarket. This helps them defend themselves against cold temperatures and changing air pressure. Google balloons will circle the earth at a height of 20 kilometers-- in a layer of our atmosphere known as the stratosphere . This is higher than the altitude at which planes fly. Once the balloons reach the desired altitude after being released from the earth, they will ride on air currents. What keeps these balloons from flying away? They will be controlled by people at the Project Loon command center. A pump operating on solar power will fill the balloon with gas to raise it or let gas out to lower it, based on instructions. This allows the balloon to float on different air currents which are moving either clockwise or anti-clockwise. There is no doubt that this technology can bring education to many children, weather information to farmers, and communication to natural disaster areas. However, one big question remains -- will some countries be comfortable with balloons above their heads? There could be concerns... Question: What's the purpose of Google's Project Loon? - Sending Internet signals to other planets in space. - Making it easier for astronauts to communicate. - Allowing people to connect to the Internet easily. - Helping us learn more about the earth's atmosphere.

They show a strong interest in the bones of their own kind.They are often seen gently touching the bones with their trunks and feet while remaining very quiet.Sometimes elephants completely unrelated to the dead will still visit their graves. Elephant researcher Meredith recalls something in his book about a typical elephant death ritual.The entire family of a dead elephant,including her young baby,were all gently touching her body with their trunks,trying to lift her. The elephant herd were all rumbling :The baby elephant was even observed to be weeping and made sounds that sounded like a scream,but then the entire herd fell incredibly silent.Then they began to throw leaves and dirt over the body and broke off tree branches to cover her.They spent the next two days quietly standing over her body.They sometimes had to leave to get water or food,but they would always return. Events of elephants behaving this way around human beings are common throughout Africa. On many occasions,they have buried dead or sleeping humans or helped them when they are hurt. An old woman fell asleep under a tree.When she woke up,there was an elephant standing over her,gently touching her.She kept very still because she was frightened.As other elephants arrived,they began to scream loudly and buried her under branches.She was found the next morning by the local people,unharmed. George Adamson also recalls when he shot all elephant from a herd that kept breaking into the farmers'gardens.George gave the:elephant's meat to 1ocal men and then dragged the rest of the body miles away.That night,the other elephants found the body,took the leg bones,returned them to the exact spot the elephant was killed,and made the death ritual. Question: The elephant watched the woman because _ . - it thought she was sleeping - it thought she was dead - it tried to protect her - it wanted to wake her up

Q: Read the following article and select the best answer. Article: Arthur Miller (1915--2005) is universally recognized as one of the greatest dramatists of the 20th century. Miller's father had moved to the USA from Austria-Hungary, drawn like so many others by the "Great American Dream". However, he experienced severe financial hardship when his family business was ruined in the Great Depression of the early 1930s. Miller's most famous play,Death of a Salesman,is a powerful attack on the American system, with its aggressive way of doing business and its insistence on money and social status as indicators of worth. In Willy Loman, the hero of the play, we see a man who has got into trouble with this system. Willy is "burnt out" and in the cruel world of business there is no room for sentiment: if he can't do the work, then he is no good to his employer, the Wagner Company, and he must go. Willy is painfully aware of this, and at a loss as to what to do with his lack of success. He refuses to face the fact that he has failed and kills himself in the end. When it was first staged in 1949, the play was greeted with enthusiastic reviews, and it won the Tony Award for Best Play, the New York Drama Critics' Circle Award, and the Pulitzer Prize for Drama. It was the first play to win all three of these major awards. Miller died of heart failure at his home in Roxbury, Connecticut, on the evening of February 10, 2005, the 56th anniversary of the first performance ofDeath of a Salesmanon Broadway. Question: What is the text mainly about? - Arthur Miller and his family. - The awards Arthur Miller won. - The hardship Arthur Miller experienced. - Arthur Miller and his best-known play.

When they saw their baby, they both cried out, "My goodness! How small it is! It's hairless and toothless! It's a monster!" They sent for all the doctors in the country and ordered them to prepare some medicine for her. "When she drinks your medicine, she must grow to the right size and have hair and teeth," the king said, "If you don't do this, you'll have a beating." The doctors thought it impossible, but they dared not say anything against the king's order. Just then and old doctor stepped forward. "Oh, we shall certainly obey your order," he said, "but it takes time. We have to dig a mineral from the Kun Lun Mountains when the snow melts for the second time. The snow melts on those mountains only once in six years. So we need twelve years." At last the king agreed and the doctors took away the little princess. On her twelfth birthday, they brought her back to her parents with long black hair and beautiful teeth. The king and queen were very happy and gave the doctors expensive presents.
