Article: In the late 1500s, a large powerful gun was placed on top of the Signal Hill, in prefix = st1 /Newfoundland, to prevent attacks from the outside. Flags were also flown there to warn sailors of bad weather. It's fitting, then, the Italian Gulielmo Marconi should have chosen this site to receive the world's first radio signal -- in Morse code -- from England on December 12, 1901. Marconi, combining earlier ideas with his own, led us to a new communications age. For the next 50 years, until the appearance of television, radio ruled the air waves. Today, it's the TV that rules. No single person can say to have invented television. In 1884, the German Paul Nipkow invented a device that sent pictures mechanically , and in 1906, Boris Rosing, a Russian, used a ray and a disc to create the world's first TV system. Then in the early 1920s, another Russian, Vladimir Zworykin,invented a picture display tube. He took out a patent for color1 TV, even though it wouldn't be developed for another 25 years. In 1924, a Scot entered the scene -- John Logie Baird. He first succeeded in sending a moving picture and a year later got the first actual TV picture. In 1926, Baird showed TV in aLondonlaboratory. Two years later inNew York, Felix the Cat became the first TV star. TV excited everyone's imagination, but hardly anyone had a set, with just two thousand in use worldwide in the mid-1930s. Since the late 1940s, TV technology has developed very quickly. Computers may finally be combined with all televisions to give people a total all-in-one communications network. Today, it's possible to sit and watch TV in the middle of a forest or in the Arctic. It's surprising when one considers that Marconi was on Signal Hill in the same century. Question: We can learn from the text that Signal Hill was once used as _ . - a site of communication - a weather station - a factory to produce weapons - a battle field to fight enemies from the outside
a site of communication

Read the following article and select the best answer. Article: Square dancing is a form of entertainment and physical exercise, which is a good thing. However, a group of senior Chinese ladies dancing in New York's Sunset Park were recently faced with noise complaints from nearby residents. The local court even served a summons related to a certain Ms. Wang. The news soon caused heated discussion across China, with many believing the incident to involve a cultural conflict between the East and West,while others view it as a form of discrimination against Chinese in the United States. The United States is a diverse society, and in many cases, Chinese dancers are tolerated and even appreciated. Meanwhile, the United States is a society based on the rule of law, and due to cultural differences, local regulations seem to be very different from those in China. As a result, some old Chinese ladies dancing in New York's Sunset Park found themselves caught in an embarrassing situation. Locals and immigrants from other nations view such noise as a violation of their right to enjoy _ . Calling the police is regarded as the most efficient way to solve such a problem. Before, these ladies probably did not understand local customs and rules. However, since the incident took place, they should perhaps know a little better next time and keep the noise to a minimum. People from different nations are often supposed to reach compromises, respecting and tolerating each other. Whatever your choice of entertainment, it is important not to affect other people's lives. Square dancing is only one of many activities during which people should mind their behavior. As for U.S. police practice, there might still be some room for improvement. Some were said to be rather rude, leading to the so-called "racial discrimination," which is a sensitive topic in U.S. society. If the involved parties could be more tolerant, and solve such problems without involving the court, perhaps immigrants would mix more. Question: What will the senior Chinese ladies most probably do after the incident? - Go back to China. - Fight for their right. - Ask America to change its law. - Keep the noise lower.
Keep the noise lower.

Q: Read the following article and select the best answer. Article: On Friday, Japanese researchers announced a population clock that showed a dangerous situation that the Japanese nation would disappear in 1,000 years if the falling birth rate kept the present level. Researchers in the northern city of Sendai said that Japan's population of children aged up to 14, which now stands at 16.6 million, was falling at the rate of one child per 100 seconds. It would lead to a terrible result that there would be no children left in Japan in 1,000 years. "If the rate keeps falling at that rate in our country, there will only be one child who is able to enjoy the following Children's Day left on May 5th, 3011," said Hiroshi Yoshida, a professor at Toholu University. "But 100 seconds later, a national disaster that there are no children left in Japan will happen," he added, "The nation's people will disappear for the birth rate has fallen to the level that every woman has no more than two children, which started in 1975." Yoshida said they created the population clock to make Japanese people pay close attention to that problem for their nation's future. Another study showed that Japan's population was expected to fall to one third of the present population amount: 127.7 million in the next century. The Japanese government predicted that the birth rate would just become 1.35 children per parents within 50 years. At the same time, Japanese life expectancy which is expected to ascend from 86.93 years in 2010 to 90.93 years in 2060 for women and from 79.64 years to 84.19 years for men has already been one of the highest in the world. More than 20 percent of the Japanese are aged 65 or over. It means that Japan has become one of the countries with aging populations in the world. The problem of aging populations is a headache for the government and the Japanese economy because there are fewer and fewer workers who can make money for the country. However, the government has to face the terrible situation that it needs to offer a growing number of pensions. Question: According to the passage, what will happen in Japan in the following 100 years? - The life expectancy will be 90.93 years for women. - The government will receive a growing number of pensions. - The birth rate will be 1.35 children per family. - The population of Japan may only be about 42 million.
A: The population of Japan may only be about 42 million.

When I went to the kitchen for breakfast, there was no cereal. I decided to have some toast instead, but I burned it. I had to eat it anyway because there was no more bread. There was no juice, either. I just had a glass of water. When I was almost at the bus stop, I realized that I had forgotten my wallet, so I had to go back home and get it. Of course, I missed the bus and had to wait for the next bus. I was late for school and the teacher told me to stay in the classroom at lunchtime to catch up on the schoolwork I had missed. After lunch, it was the time to give the teacher our homework. I reached into my bag to get it but it wasn't there. I had left it at home. I was in trouble again.
