I'm taking a test and have to guess the right answer to the question after the article. Article: Hong Kong is one of the most densely populated cities in the world, but with night skies around 1,000 times brighter than globally accepted levels, it gains a bad reputation for its light pollution. A study by Hong Kong University found that brightness levels in the southern Chinese city's popular shopping district of Tsim Sha Tsui were 1,200 times greater than the international dark sky standard. The crowded city of 7 million residents , full or residential high-rises, towering office blocks and neon advertisements, has no laws to control outdoor lightning. The result is that light pollution is thought to be much worse than in other large cities, including London, Sydney, Tokyo and Shanghai. "In Hong Kong , you can't go anywhere outdoor in the evening without your eyes being blinded by this really disturbing outdoor lightning," the light pollution survey's head Jason Pum told AFP. "The fact that we have all this light in the sky means energy is wasted," he said, adding that too much artificial lightning also affects nightly wildlife. Research has suggested that light pollution can cause a number of harmful health effects in humans, including sleeplessness and headaches and can also interrupt body clocks and hormones . The university survey, the result of five million measurements taken from points across the city, was released just days before the start of the annual Earth Hour event, organized by the World Wildlife Fund. People around the world will be encouraged to turn off the lights for an hour on Saturday night to raise awareness of climate change. Last year, a number of Hong Kong's major buildings along Victoria Harbour went dark to mark Earth Hour. "Anyway, we should do our best to reduce the amount of lightning and adjust it for the benefit of the environment." Question: .We can know from the passage that _ Options: A: light pollution in Hong Kong is among world's worst. B: light pollution is the biggest problem in Hong Kong. C: Earth Hour is simply organized to reduce pollution. D: light pollution is the primary causes of sleeplessness.

I'm taking a test and have to guess the right answer to the question after the article. Article: Work your brain! Between 2 and 3 pounds of wonder, it controls everything we say, do or think, who we are and what we care about, the way we walk or laugh or figure out things, what we like and the talents we possess, how we see and talk and run and jump and process our food. The brain uses 20 percent of our body's oxygen and 20 percent of its blood. Somewhere within its protein, fat, 100,000 miles of blood vessels and 100 billion nerve cells, it helps us remember where we put our gym shoes. Change our temperature so we don't die because of the heat or cold. Speed us up or slow us down. Help us choose between orange juice or orangeflavored drinks. Its complexity are stunning, far beyond anything most of us can imagine. To keep this work of art as polished as possible we need to eat right, exercise and keep mentally stimulated. Good nutrition helps brain cells communicate with each other. Exercise stimulates a hormone in our brain that improves memory. Mental stimulation keeps you sharp even as you age. "It's very important that we tell people to be physically active and mentally active," said neurologist Malcolm Stewart. "People cannot stop aging, but you're able to reduce the damage; you're able to keep the function up." Following are Dr.Stewart's advice for improving brain health: l Nutrition Avoid fast food. Follow the old adage : For breakfast, eat like a king; for lunch, like a queen; for supper, like a beggar. l Exercise Do a combination of stretching aerobic and musclestrengthening every day. l Mental games Try to have a sense of hope about the future. Do puzzles. Listen to music. Reach out to others to make their lives better. Question: In order to keep brain healthy,we should avoid _ . Options: A: eating a good lunch B: doing puzzles C: eating a large supper D: taking aerobic exercise

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: From bankers to factory staff, employees in the West face a cold _ of losing their jobs as a global recession starts to bite. For colleagues in the East, the pain is more likely to come through a pay cut. Human resource experts say cultural differences explain why Asian companies try harder to preserve jobs in difficult times, which will prevent unemployment and may help Asian economies survive at a time of slowing exports. The East Asian attitude may also make it easier for companies to recover quickly from the economic downturn since they will not need to rehire or train new staff, but build up a more loyal and devoted group. "In the Confucian mindset , the right thing to do is to share the burden , which is the sense of collective responsibility. While in the West, it's more about individual survival," said Michael Benoliel, associate professor of organizational behavior at Singapore Management University (SMU). In contrast, local Western companies from General Motors to Goldman Sachs plan to lay off workers by the thousands, but at the Asian units of Western multinationals or western units of Asian groups, job cuts will probably be less severe. Japan's jobless rate was 4 percent in September, up from 3.8 percent in January, while Hong Kong's was flat at 3.4 percent. But US unemployment is expected to have jumped to 6.3 percent last month from below 5 percent in January. Experts say that while there are noticeable differences in labor practices in East and West, the gap will narrow as more firms become more multinational and competition forces firms to adopt the best practices of rivals from abroad. Question: The passage mainly tells us _ . Options: A: the difficulties all the companies around the world will meet with today B: the different labor solutions of Asian and Western in global recession C: the ways to cut down the cost of the companies in economic downturn D: the cultural differences between Eastern and Western world at present
A: B
Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Speakers of different languages not only describe the world differently but think about it differently too, according to a new study. Researchers used a cartoon cat Sylvester to study how language was reflected in the gestures people made. Dr. Sotaro Kita of the University of Bristol's Department of Experimental Psychology , showed the cartoon to a group of native English, Japanese and Turkish speakers and then watched their gestures as they described the actions they had seen. He found speakers of the three different languages used different gestures to describe the same event, which appeared to reflect the way the structure of their languages expressed that event. For example, when describing a scene where the cat swings on a rope, the English speakers used gestures showing an arc trajectory and the Japanese and Turkish speakers tended to use straight gestures showing the motion but not the arc. Dr. Kita suggests this is because Japanese and Turkish have no proper verb to express the English meaning "to swing". While English speakers use the arc gesture as their language can readily express the change of location and the arc-shaped trajectory, Japanese and Turkish speakers cannot as easily express the idea of movement with an arc trajectory so they use the straight gesture. Dr. Kita said, "My research suggests that speakers of different languages cause different spatial images of the same event in a way that matches the expressive possibilities of their own languages. In other words, language influences spatial thinking at the moment of speaking." Question: 69. After watching the gestures of speakers of the three different languages, Dr. Kita concluded that _ . Options: A: Japanese and Turkish people couldn't express the meaning of "swing" B: English was obviously better than Japanese and Turkish C: no word in Japanese and Turkish could express some ideas of English D: every language had its own special way to describe things
A: D
