Q: I'm taking a test and have to guess the right answer to the question after the article. Article: When Christopher Columbus landed on a land without name in 1502, he saw many Indians wearing gold earrings. So he thought the land must be rich in gold. He named the place Costa Rica, which means "rich coast" in Spanish. Though little gold was found, Costa Rica today is indeed rich with coffee and bananas. Coffee is the most important product in Costa Rica and most of it is exported to other countries like America and West Germany. Bananas are the country's second most important export. Costa Ricans also grow many other crops such as fruits, corn and beans for their own use. Costa Ricans love colors and their houses are painted in bright colors. Education is very important to the Costa Ricans. Almost every village has a school and education is a must for children between seven and fourteen years of age. Boys and girls go to separate schools. Classes begin in March and end in November. The other three months of the year are harvest time and the children have to help their parents to pick coffee beans. Question: The Costa Ricans may NOT paint their houses _ . Options: A: pink and red B: grey and black C: blue and green D: yellow and orange

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Chemicals used for industrial processes often create dangerous forms of waste. The amount of these chemicals has risen heavily in the past few years, as more areas of the world industrialize and new products are produced. Over 80,000 different chemicals are used in industries world wide. Around the world hundreds of millions of tons of harmful waste are produced each year. Often, it is difficult and expensive to get rid of these chemicals or to store them in a way that does not endanger human life and the environment. Every year, major health problems result from harmful waste. Sadly, it is often when someone has died or, become seriously ill that governments will take action and reduce levels of dumped harmful waste. In 1989, a school inprefix = st1 /New Jerseyhad to be closed because students there had suffered too much exposure to chromium. It was later learned that large amounts of chromium had been dumped nearby and blown over to the school area. Research has been done to provide information on the effects of every chemical. Because waste chemicals often mix together, it will also be necessary to learn how the combinations of these chemicals affect human health. Some governments have realized how serous the problem is and are making laws to get rid of harmful waste. They are also trying to limit the amount of waste industries are allowed to produce. Not only governments but the public as well must form part of the solution. They can choose not to buy those products which require the production of harmful waste, attempt to affect policymakers, and produce less harmful waste themselves. Many scientists think that waste production can be cut. The waste can be reduced by at least one-third using existing technologies and methods. Question: What is mainly discussed in the text? Options: A: The effect of every chemical. B: Problems of harmful waste. C: Chemicals used for industrial processes. D: Events related to waste chemicals.

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: The new high-speed railway line between Urumqi,capital of the Xinjiang Uygur self-governing region,and Lanzhou,capital of Gansu province,has cut train travel time by half to less than 12 hours. The dramatic improvement will benefit many families planning reunions for Spring Festival. "For the first time,I feel home is not that far away after all,"said Liang Shaofu as he boarded a high-speed train in Urumqi with six members of his family. The 35-year-old left Lanzhou to set up a dry fruit business in Xinjiang eight years ago,and he has now settled in Urumqi. The 1,776-km line,which passes through Qinghai province and is the country's first high-speed railway to be built in a high-altitude region,came into service on Dec 26. "We normally drive home for Spring Festival to avoid the difficulties of buying seven train tickets for the whole family during the peak season,"Liang said."Driving can be very tiring and dangerous sometimes,so one year we even decided not to go back to Lanzhou simply to avoid the trip." More than 600,000 passengers traveled on the line during its first month,and the Urumqi Railway Bureau said the introduction of high-speed services will ease transport pressure during the Spring Festival peak season. The existing usual railway line could no longer support Xinjiang's development.All passenger trains will gradually shift to the new link,leaving the old one to be used for goods.As a result,Xinjiang's annual goods ability could reach 200 million metric tons from the current 70 million. The line passes through areas that experience high winds,and it also crosses parts of the deserted Qinghai-Tibet Plateau and the bone-dry sands of the Gobi Desert. The project could help China to promote its high-speed railway technology abroad,said Ma Xi zhang,director of the Lanzhou-Xinjiang railway project's _ management department in Xinjiang. Question: From the passage we can learn _ . Options: A: Xinjiang's annual goods ability can increase nearly four times B: the new railway technology may help more railway lines to be built abroad C: the high-speed railway lines can't be built across the bone-dry sands D: the old railway lines can only carry goods now
A: B

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Google is testing its newest high-tech device, Google Glass. Most of the technologies for Google Glass are already available on smart phones. Google has taken those same technologies and added them to eyeglass frames . The company describes the glasses as wearable computers that would change the way people view others and the world. "Google Glass is a tiny computer that sits in a lightweight frame, and rests neatly above your eye and it makes exploring and sharing the world around you a lot easier," said Chris Dale, the Senior Manager of Communications for Google Glass. The glasses have a tiny video screen and a camera that connect wirelessly to the Internet through WIFI, a smartphone, or a tablet computer. You can make and receive calls, send and receive texts, take pictures, record video or search the web. You control Google Glass using your voice, and a touchpad on the right arm of the frame. Professor Marcia Dawkins is among a select group of people who have been given a chance to test out Google Glass. "I thought this is something I definitely need for my classroom and hopefully for my personal life too." The Professor's Google Glass looks like a pair bright orange glasses, without the actual glass. But there's a tiny rectangular glass at the top right-hand corner. Through that glass, she has been recording video while biking. She also has been able to talk to her sister in Thailand, and she plans to use the device to teach a public speaking class. But not everyone is excited about Google Glass. Some are concerned about possible risks to privacy. John Simpson is the director of the privacy project at Consumer Watchdog. "It is going to allow people to come in and spy on you and record that, without you knowing what is going on." Filmmaker Chris Barrett showed just how easy it is to record people without them knowing it. His glass captured a man getting arrested after a fight. He shared the video on You Tube. Also some are concerned about the use of facial recognition technology on Google Glass. But Google... Question: What can be inferred from the passage? Options: A: Google has done what it can to protect people's privacy. B: Google Glass may be used for bad purposes. C: Most people feel worried about the use of the Glass. D: Google Glass is more useful than smartphones.
