[Q]: Article: Let's pretend we're sailing down the Rhine River on a pleasure boat. The Rhine is one of the main waterways of Germany, and the river traffic is heavy. It's interesting to watch the many boats going up and down the river. But the river traffic is not nearly so interesting as the beautiful scenery along the banks and hillsides. The boat is passing many old castles. We can see people working in the vineyards on the hillsides. There are vineyards as far as the eye can see. Wine from the Rhine Valley is famous all over the world. Suddenly our boat slows down and begins to turn a little. We are coming to a sharp bend in the river. On our right we can see a rocky cliff over 400 feet high. At first it looks quite ordinary, but there is nothing ordinary about it. There are many stories, poems, and songs about the cliff. We are looking at the Lorelei. Then someone on the boat begins to sing in German, the song of the Lorelei. It is a song about a beautiful siren who has lured many sailors to their deaths. The siren is supposed to sit on the rock combing her long golden hair and singing. The sailors who hear her forget to steer , and the current of river hurls their boats on the rocks and dashes them to pieces. Soon other people on the boat begin to sing. The beautiful song adds to special magic to the moment, and you begin to realize why so many people have made this trip down the Rhine to see the rock of the Lorelei.

[Q]: Article: In the market of luxury brands, Chinese consumers are only second to the Japanese in the world. Across the globe it's clear that the young generation are increasingly relying on expensive brands for their self-image. Personally I am a fashion-lover, at least in spirit. I love to look at clothes and shoes. But I don't understand why people spend large amounts of money on designer labels. Certainly, young people, whether in China or elsewhere, should be building their self-confidence in other ways. When a young woman shows off a handbag worth two months' salary, that's a scary thing. What are the psychological factors forcing young people to take on debt for designer items? The desire to say, "Hey, look at me. I'm wealthy. I have social status." Scientists have found the acquisition of luxury brands doesn't lead to happiness. Study after study has shown that, although we are born to desire material possessions, when we get them, we don't suddenly become "happy people". In fact, a series of studies by Leaf Van Boven at the University of Colorado, US, have shown that individuals who invest in travel and other experiences get more pleasure than those who invest in material things. That's because experiences are more easily combined into a person's identity. If I travel to Yunnan, that adventure affects how I think. My memories entertain my friends and colleagues. It follows, then, that investing in experiences improves my chances for successful social relationships. Moreover, as Van Boven has observed, young people who pursue happiness through "things" are liked less by others than young people who seek happiness through experiences. This research is pretty solid, but I suspect it won't persuade young people not to desire a style. It's natural to want to express yourself through your appearance. So my advice is, create a look that isn't tied to a designer label. You don't have to _ to send a message about who you are. Take a trip. Go out into the world. Then come back and confidently create your own signature look.
Question: This passage is written here in order to _ .
Options: (A) encourage young people to travel (B) persuade young people to seek experience happiness (C) report the result of a series of researches (D) advise young people to save money

[Q]: Article: The Beginning of the Civil Rights Movement In 1955,bus seats for African Americans and whites were separated in parts of the U.S.. On December 1,1955,in the city of Montgomery,Alabama,a conflict,or disagreement,started when an African American woman named Rosa Parks refused to give her bus seat to a white man and go to the back of the bus. The police took 42yearold Parks to jail. The African American community was extremely angry. They had a meeting and decided to work together to protest discrimination. They agreed to boycott the buses on the day that Parks went to court. The day was a success. Empty buses drove through the streets. The city lost money. The community decided to continue the boycott. They elected a man named Martin Luther King,Jr. to be the leader. The boycott continued. It was difficult for African Americans to get to work without buses,but they didn't stop the boycott. The city continued to lose money. Finally,the U.S. Supreme Court decided that Montgomery's bus laws were unfair and gave the African American community equal right. On December 21,1956,the bus boycott ended. The Montgomery Bus Boycott was the beginning of the Civil Rights Movement. The movement eventually led to the Civil Rights Act in 1964,a set of laws that made discrimination a crime. During the Montgomery Bus Boycott,people worked together to change the government. Today,people in the U.S. continue to work together for a change. Now hundreds of organizations and community groups work to protect the rights of U.S. citizens and residents.
