    To me, music is food and water. Life without music would not be 1. I know this is not true for everyone in the world. It is because a lot of people get along quite well without 2 concerts or listening to records. But music plays a(n) 3 part in everyone's life, whether he or she realizes it or not. Try to 4, for example, what films or TV plays would be like without music. Would the feelings and the moving stories be so exciting or dramatic (戏剧性的)? I'm not sure about that. Now, we have been speaking of music in its more common 5 —the kind of music we hear in the concert hall. But if we look at some parts of music more closely, we will 6 it in our daily life too —in the rhythm (节奏) of the sea, the melody (曲调) of a bird and so on. So music 7 has meaning to everyone, in some way or another. And, of course, it has special meaning to those who have spent all their 8 playing or writing music. Through music a child enters into a 9 of beauty, expresses himself from his heart, feels the joy of doing things alone, learns to take care of others, develops his mind and makes his body 10. So, enjoy your favorite music in your free time. You will find something special in it.

    There was a new restaurant in the street. The restaurant said it had the longest menu in the world. The manager also said that the restaurant could provide any dish, no matter how unusual it was. If they couldn't offer it, people could choose any prize from the restaurant. A man was happy to hear it and walked into the restaurant.

    The man studied the menu carefully and decided to make sure if (是否) it was true. He would like to order a very unusual dish.

    When a waiter came up to take his order, the man said, "You say you can provide any dish. Really?"

    "Of course, sir. We never disappoint our customers (顾客)."

    "Well," the man said, "I want to have a sandwich with apples from a giant's house."

    The waiter wrote down the man's order. "Very good, sir," he said. "That shouldn't take long." The waiter walked away quickly. A few minutes later, the man became happy again as he saw the waiter return with nothing in his hand.

    "You disappoint me this time, don't you?"

    The waiter made an apology. "I'm so sorry, sir. We have fewer waiters today," he said, "so I'm afraid you need to join us to take your food out of the kitchen."

    Dogs are known for their sense of smell. They can find missing people and things. Now a study shows that the animal can even find bladder cancer (膀胱癌).

Cancer cells can produce chemicals with unusual smells. Scientists think dogs have the ability to smell these smells, even in very small amounts, in urine (尿).

    For example, a dog showed great interest in the growth of its owner's legs. The man was later found to have skin cancer. Carolyn Willis and some scientists trained different kinds of dogs for the experiment. The study used urine collected from bladder cancer patients (病人), from people with other diseases and from healthy people. Each dog was tested 8 times. In each test there were 7 examples for the dog to smell. The dog should show the one from a bladder cancer patient by lying down next to it.

    Their results later appeared on the British Medical Journal. In all, 36 bladder cancer patients and 108 other people attended. During the training, all the dogs even found cancer in a person who had been tested healthy before the study. Carolyn Willis said dogs could help scientists find the chemicals produced by bladder cancer. The information could then be used to develop machines to test for the chemicals. The team also plans to use dogs to help find other kinds of cancer.

    In 1997, a spaceship called Cassini was sent to explore Saturn (土星) and its moons. Now Cassini's mission (使命) has come to an end. Scientists made it fall and bum up in 2017. But before that happened, the spaceship had made many trips between Saturn and its rings, sending photos and other information back to the Earth.

    Cassini was a project carried out by NASA, the European Space Agency and the Italian Space Agency. It took Cassini about seven years to reach Saturn.

    Scientists have learned many exciting things from Cassini. In 2005, Cassini sent a space probe (探测器) to Saturn's largest moon, Titan, so scientists could get a closer look at the moon's surface. One of the most important discoveries Cassini made was that there is warm liquid water (液态水) under the ice that covers one of Saturn's smaller moons, Enceladus. Scientists believe con­ditions on Enceladus could be similar to the conditions that led to the development of life on Earth.

    Cassini's mission was supposed to be ended in 2008, but because it was still in good shape, scientists increased its life to 2017. Cassini per­formed the last task of its mission on September 15, 2017.

    When Cassini ran out of its fuel (燃料) and entered Saturn's atmosphere (大气层), it burned up. Scientists said it was necessary for Cassini to be totally destroyed (毁坏) so there was no chance that microbes (微生物) from the Earth could be harmful to any possible life on Saturn.
