However, the last of the ladybirds was late in getting back. He hadn't managed to reach the lake. Everyone criticized him, and they prepared to continue their journey the next day. Following their new guide, they spent a morning walking northwards until they reached some tall thick grassland, where they stopped. There were no clear waters or flowers in front of them. The heavy rain had turned the place into a huge green puddle . Everyone understood what had happened. When the ladybirds had gone out looking for the lake, they had gone in the wrong direction.

Article: Signs in Chinese will be set up in public areas such as airports, to benefit Chinese travelers, the Italian Government announced in late February. _ . Despite the different languages, travel across Europe has never been so simple. Just five years ago, if you wanted to visit Germany in the north and Spain in the south in one trip, you had to wait for weeks to apply for different visas from the two countries. You also needed a calculator because both countries had different money. Today, with a Schengen Visa issued by any member country, you can travel across 15 European countries without stopping. Since 2002, within most of the EU, there is now just one type of money called the Euro. The Euro was designed to be the only money in the EU, and already makes it easier to shop around. If you drive, your driving license and car insurance policy are valid in the other European countries. And you can use your mobile phone everywhere. All the countries in the continent are melting into a united Europe under the EU. For Europeans and visitors, the result is that it is more convenient to travel back and forth between the different countries. Question: It can be inferred from the passage that _ . - an increasing number of Chinese tend to travel to Europe - Chinese has become an important language in Europe - the Euro is the only money used in the EU now - it is always necessary to unite many countries into one

Ques: Read the following article and select the best answer. Article: Richard Wagner was a German musician has been a very controversial person, but he has gained great fame by writing opera, a form of performance combining singing, music on instruments, and drama. While he wrote excellent music, many people think his operas are too dark and serious, lacking the fun common in operas written before his time. Wagner, on the other hand, thought the opera of his time was too simple.He wanted to make opera a serious form of art that combined drama and music to tell deep stories that would have a strong effect on the audience. Some people thought Wagner's new kind of music was too different from the operas they were used to hearing.Wagner agreed with them.In fact, he didn't call his works "operas" at all, using instead a German word that means "Musical Festival" or "Musical play". While many people today still do not like Wagner's operas, they cannot deny that Wagner has had a lot of influence on opera as a form of art.Wagner invented the tradition of turning off the lights before starting a play.He also was the first person to make the whole audience sit down for an entire play.Today, almost all operas are performed in this manner. Wagner as a man was even more controversial than Wagner as a writer of music.He hated Jewish people, and made many people angry, which we would today think of as evil.Some would say he was a good musician, while others would say that he was a bad musician.But it would be difficult to say he was not an important person in music and in the world. Question: Why did Wagner write what is considered serious music? - He wanted to influence people with deep stories. - He wanted to make his music simple to follow. - He wanted to make it suitable for his deep voice. - He was greatly influenced by previous musicians.
Ans: He wanted to influence people with deep stories.

Read the following article and select the best answer. Article: Dogs are known for their sense of smell.They can find missing people and things like bombs and illegal drugs.Now a study suggests that the animal known as man's best friend can even find bladder cancer. Cancer cells are thought to produce chemicals with unusual odors .Researchers think dogs have the ability to smell these odors, even in very small amounts, in urine .The sense of smell in dogs is thousands of times better than in humans. The study follows reports of cases where, for example, a dog showed great interest in a growth on the leg of its owner.The man was later found to be skin cancer. Carolyn Willis led a team of researchers at Amersham Hospital in England.They trained different kinds of dogs for the experiment.The study involved urine collected from bladder cancer patients, from people with other diseases and from healthy people. Each dog was tested 8 times.In each test there were 7 samples for the dogs to smell.The dog should signal the one from a bladder cancer patient by lying down next to it.Two cocker dogs were correct 56 percent of the time.But the scientists reported an average success rate of 41 percent. The British Medical Journal published the research.In all, 36 bladder cancer patients and 108 other people took part.During training, all the dogs reportedly even identified a cancer in a person who had tested healthy before the study.Doctors found a growth on the person's right kidney . Carolyn Willis says dogs could help scientists identify the combined chemicals produced by bladder cancer.That information could then be used to develop machines to test for the chemicals.The team also plans to use dogs to help identify markers for other kinds of cancer. Question: What's the general idea of the text? - Dogs have a good sense of smell - Dogs can help cure cancer - Dogs can smell cancer - Dogs help perform experiments
Dogs can smell cancer
