Q: Read the article and select the best answer. Article: Around the world coral reefs are facing threats brought by climate change and great changes in sea temperatures. While ocean warming has been the primary focus for scientists and ocean policy managers, cold events can also whiten corals. A new study by scientists compared damaged to corals exposed to heat as well as cold stress. The results show that cool temperatures can cause more damage in the short term, but heat is more destructive in the long run. Climate change is widely known to produce warming conditions in the oceans, but extreme cold-water events have become more frequent and serious as well. In 2010, for example, coral reefs around the world faced on of the coldest winters and one of the hottest summers on record. During a unique experiment, corals under cold temperatures suffered greater damage in just days compared with heat treated corals. Yet the researchers found that corals were eventually able to adjust to the cold conditions, make their health stable and continue to grow. However, over the long term corals subjected to heat suffered more greatly than those in cold, with evidence of severe whitening and growth stoppage, which leads to death. The coral's ability to adjust to cool temperatures surprised the researchers, who say the study's results show the complexities of monitoring coral health in response to different environmental factors . "Global warming is associated with increases but also decreases of temperatures," said Deheyn, one of the researchers. "Not much has been known about the comparative effects of temperature decrease on corals. These results are important because they show that corals react differently to temperature differences, which is important for future management of coral reefs in the field of climate change." Question: Scientists reached the conclusion through _ . Options: A: news report B: scientific study C: great imagination D: natural conditions
A: B

Q: Read the article and select the best answer. Article: It's true to say that technology makes our lives easier. However, increasingly scientists are saying that we need to give ourselves a break-----otherwise we put ourselves at risk of developing hundreds of health problems. Over the summer the days are longer and sunnier. Why not put this free time to good use and do something away from technology? You could learn a new skill. There are hundreds of possibilities: cooking, a musical instrument or a new sport. Haven't you always wanted to learn how to knit ? You could use your free time to practice these new things, which might lead to an exciting opportunity in the future. If you just want to relax, why not head to a beach? Take along your favorite book and relax on the sand, or go for a walk along the coastline. If you don't live near a beach, you could go to your local park. Why not have a picnic, or try to explore some of the local wildlife? You could even get involved in the latest craze : adult coloring books! Coloring is a surprising thing to help you relax, and it can be a nice way to escape from the stress of modern life! Whatever you choose to do, try something new! You might surprise yourself and find a hidden gift within you; you might make new friends along the way. Next time you find yourself changing TV channels from one to another without a clear purpose, think about what else you could spend your time doing. Question: According to the text, technology _ . Options: A: makes our life harder B: may bring us illness C: keep us busy D: gives us a break from work

Q: Read the article and select the best answer. Article: On October 23, 2011, David Pologruto, a high school physics teacher, wasstabbed by his smart student Jason Haffizulla. Jason got straight A's and was determined to study medicine at Harvard, yet this was his downfall. His physics teacher gave Jason a B, a mark Jason believed wouldundermine his entrance to Harvard. After receiving his B, Jason took a butcher knife to school and stabbed his physics teacher. How can someone as smart as Jason do something so dumb? Studies show there is little or no correlation between IQ and emotional intelligence. During my early university years, I regarded myself as an intelligent guy. I got good marks in mathematics, physics, and other subjects. I thought such skills would surely give me a bright future. After one year of study with decent marks, I began to see two major classes of students. The first category of students turned up to few lectures, partied every weekend, enjoyed a great social life, and did minimal work to pass courses. The second category of students were intelligent and hard workers who got good grades and were very focused on their studies. Surely would these intelligent and hard-working students find the great jobs before the other lazier class of students? Not so. Students are often shocked upon graduation that their qualifications are not as important as they once thought. Graduates enter the workforce only to realize that co-workers hate them and less intelligent people are the ones receiving promotions. Educational skills are useless in some industries when interpersonal skills are absent. You can have great ideas, theories, and solve complex problems, but if you cannot effectively communicate in a persuasive and exciting manner by relating to your fellow humans, you will face an uphill battle in whatever challenges you encounter. It's not that people dislike you because of your intelligence; it's that people dislike you because you're rude and not understanding. The intelligent person with poor communication skills is insensitive or unaware of... Question: Jason Haffizulla stabbed his physics teacher because _ . Options: A: he was unfairly treated by his teacher B: he was disappointed with his downfall C: he was not smart enough at studies D: he got a worse mark than usual
A: D

Q: Read the article and select the best answer. Article: In 1896, Einstein went to Zurich to study physics. There he met a girl from Hungary. They studied in the same class and the same interest in physics brought them together and they became good friends. Before long they fell in love. In 1903 when Einstein was 24, he married Merits, who was 4 years older than he. After their marriage, Einstein devoted himself to the research of the great theory. To give her husband more help, Merits gave up her own work, and became a good wife and assistant. She tried her best to encourage him whenever possible. She was sure that her husband would succeed. They often discussed the theory while walking outside or sitting together in the room. They even did that in their letters when one of them was away from their home. In1914, Einstein moved to Berlin and _ there. At that time his theory proved to be correct and he had become famous all over the world. But it was not long before the First Would War broke out. Merits as well as her two sons, who were on holiday in Switzerland, couldn't come back to Berlin any more. The war not only stopped Einstein's work but also broke up the warm, happy family. In 1919, Einstein and Merits had to get divorced . Question: In which year was Merits born? _ Options: A: 1896 B: 1875 C: 1883 D: 1879
