Read the following article and select the best answer. Article: An American spacecraft is moving closer to a dwarf planet called Ceres . The American space agency's Dawn spacecraft is set to reach the planet-like object in March. Space agency scientists will then place Dawn in an orbit around the dwarf planet. Agency scientists want to know more about ice on Ceres. The spacecraft will gather clues about whether Ceres may have once had conditions to support life as we know it. Dawn left Earth more than seven years ago on a trip to explore Ceres and another dwarf planet, called Vesta . Both dwarf planets are in the main belt of asteroids , a group of large objects, between the planets Mars and Jupiter. Marc Rayman is the chief engineer and director of the Dawn mission. Scientists call Vesta and Ceres "protoplanets ". Mr. Rayman says they were in the process of becoming full-size planets when, in his words, "their growth was terminated ." Scientists believe Ceres is made of rock, and covered with ice. The Dawn mission is based in Los Angeles, California. Scientists there send second-by-second commands to the spacecraft. They direct its every move, including telling it what pictures to take. Dawn will make a map of the dwarf planet. It will also try to discover how Ceres' surface has changed. Carol Raymond is the deputy principal investigator of the project. He says Dawn made an unexpected discovery while orbiting Vesta. "Instead of being bone dry, which we expected, there were _ on the surface of Vesta that showed significant amounts of water bound in the rocks and possibly even free water that could have flowed on the surface in the past." She says that if Earth's water came from wet worlds like Vesta and Ceres, then life could have developed there, too. If Dawn finds that the environment of Ceres could have supported life, scientists may seek to explore the dwarf planet with other scientific instruments. Dawn will gather information about Ceres until the middle of 2016. It will then continue to orbit the small planet. Question: Which of the following about spacecraft Dawn is true? - It was sent into space in 2008. - It is orbiting around the dwarf planet Ceres. - Its destination is just the dwarf planet Ceres. - It will gather information about Ceres until early 2016.
It was sent into space in 2008.

Read the following article and select the best answer. Article: An African proverb says that a single hand cannot tie a bundle. Everyone needs companions to help them sail through the rough seas of life. Even the strongest and richest person still needs friends. Our money and strength would have no value if we had no friends to share with us. The best friendship is a give-and-take relationship. We need the support of our family, friends and the community. In turn we also give support to the society, our friends and our family. The word "friend" has many meanings. It could be the bus driver who takes you to and from work every day. It could be a parent, a colleague, a wife or husband, a brother or sister, or even the unknown person who helped you just once when you could not find your way. Real friends share not only our happiness but our sorrows as well. This may explain why we have the expression "a friend in need is a friend indeed". Friendship is like the sunshine that keeps us warm. It is like the refreshing raindrops on the fields that give the farmers hope of a good planting season. Without friends our life would be like a desert where our only friend would be loneliness and sadness. The most fortunate person is the one who has friends from all levels in the society. A driver might find friends not only among his colleagues but among farmers, bankers, traders, students, politicians or teachers. We should never forget our old friends when we make new ones. We should treasure each of our friends whether poor or rich, beautiful or not. Each friend is _ in his or her own way. And all together, they enrich life and make it very colourful. Question: What is the main topic of the passage? - How to sail through the sea of life. - Friends and friendship. - A friend in need is a friend indeed. - Never forget old friends when making new ones.
Friends and friendship.

Read the following article and select the best answer. Article: The man who invented Coca-Cola was not a native Atlanta, but on the day of his funeral every drugstore in town shut up the shop in honor of him. He was John Styth Pemberton, born in 1833 in Knoxville, Georgia, eighty miles away. Pemberton was a chemist, sometimes known as Doctor, who, during the Civil War, became an officer and led a cavalry troop. He settled in Atlanta in 1869, and soon began making such patent medicines as Triplex Liver Pills and Globe of Flower Cough Syrup. In 1885, he registered a trademark for something called French Wine Coca-Ideal Nerve and Tonic Stimulant. A few months later, he formed the Pemberton Chemical Company, and hired an accountant named Frank M. Robinson, who had not only a good head for figures, but, attached to it, so unique a nose that he could judge the ingredients of a batch of syrup merely by sniffing it. In 1886 --- a year in which, as contemporary Coca-Cola officials like to point out, the English writer Conan Doyle made Sherlock Holmes known publicly and France found the truth about the Statue of Liberty --- Pemberton invented a syrup that he called Coca-Cola. It was a change of his French Wine Coca. He had taken out the wine and added a bit of caffeine, and, when the end product tasted awful, had thrown in some cola nut oil and a few other oils, mixing the mixture in a three-legged iron pot in his back yard and swishing it around with an oar. He distributed it to soda fountains in used beer bottles, and Robinson, with his elegant account's script, instantly designed a label, on which "Coca-Cola" was written in the style which is still employed. Pemberton looked upon his mixture less as a drink than as a headache cure. One morning in 1886, a man suffering from a headache dragged himself into an Atlanta drugstore and asked for a bottle of Coca-Cola. According to usual practice, druggists should pour a teaspoonful of syrup into a glass of water, but at that time, the man on duty was too lazy to walk to the fresh-water tap. Instead, he mixed the syrup with some soda... Question: How did Pemberton change French Wine Coca formula to make it taste delicious? - He mixed it with several oils instead of water. - He put some beer into the mixture. - He added more coffee into the mixture than before. - He added some cola nut oil and a few other oils.
He added some cola nut oil and a few other oils.
