In one of the strongest indications of the power of the mind to influence the body, a growing collection of evidence finds that people who are depressed have a greatly higher risk of developing heart disease. In a study of almost 3, 000 men and 5, 000 women, depressed men were 70 per cent more likely to develop coronary   heart disease than those who weren't depressed. While depressed women were just 12 per cent more likely to develop heart disease, those who were severely depressed were 78 per cent more likely. In fact, a 1998 study found that women who are depressed have a risk of dying from heart disease equal to that of women who smoke or who have high blood pressure. The link works the other way around, too: While about 1 in 20 American adults experience major depression in a given year, that number jumps to about one in three among those who have survived a heart attack. The more severe the depression, the more dangerous it is to your health. But some studies suggest that even mild depression, including feelings of hopelessness experienced over many years, may damage the heart. Other studies suggest depression may affect how well heart disease medications work. Researchers are n' t sure what the connection between depression and heart disease is, but theories exist. One is that people who are depressed tend not to take very good care of themselves. They' re more likely to eat high-fat, high-calorie "comfort" foods, less likely to exercise, and more likely to smoke. But beyond lifestyle, there is probably also a physiological link between depression and heart disease. Recent studies found that people with severe depression tended to have a lack of heart-healthy 0-3 fatty acids. People who are depressed also often have high levels of stress hormones  . These keep the body primed for fight or flight, raising blood pressure and causing the heart to beat faster, all of which put additional stress on coronary arteries   and prevent the body' s natural healing mechanisms from working properly. A whole branch... Which of the following can be the best title of the passage? A) Depression--Heart Disease Risk Factor. B) Heart Disease--Health Killer. C) Depression--Mental Health Enemy. D) Heart Disease--Depression Factor.

It was when I was attending high school that I first read Asimov's stories. At the time, a few science fiction magazines began to introduce this author, and to translate a few pieces from his "Robot Series". Of Asimov's works, the one that left the deepest impression on me was Pebble in the Sky. This novel directly influenced my early science fiction writing. Asimov was one of the leading writers of western science fiction's Golden Age, so although his writing may not have a direct influence on writers of today, his underlying   influence on many levels is undeniable -- the famous Three Laws of Robotics, and many classic writing techniques, for example. Asimov's novels are marked by a fully integrated   logical system, and his stories are a pleasure to read. This is the reason his novels still attract readers today. Naturally, western science fiction has few people these days who follow Asimov's creative methods. But still the majority of Chinese science fiction readers would rather read the classic works of Asimov. Compared with the "Robot Series", Asimov's "Foundation Series" is a little less well-known in China. In fact, the "Foundation Series" creates an entire world, even grander than that of the "Robot Series"; this science fiction had a direct influence on later western science fiction, the most famous example being Star Wars. In the writer's opinion, Asimov's "Foundation Series"   _  . A) was not as successful as his "Robot Series" B) is better known to readers than his "Robot Series" C) was more logically organized than his "Robot Series" D) was written better than his "Robot Series" in some ways

Mail lay scattered across the kitchen table. I couldn't put off sorting through it any longer. I checked the envelopes, putting aside the ones addressed to my husband. It had been over three years since Bob had died. To friends and family it looked like I had moved past the worst of my sorrow. I took care of my house, socialized and kept up with community. On the outside everything appeared to be normal. But inside I was anything but I worried I would never get better, never be myself again. They say sorrow has no set time limit, but I was so tired of feeling empty and hopeless. My sorrow was sharp and fresh as ever. It was like a wall of pressure in my chest, pressing my heart. I picked up a piece of Bob's mail and held it out to tear in half, but stopped myself from cutting up the envelope. The letter was from an organization that funded a Haitian orphanage called _ . Its founder, Carol Hawthorne, had given a presentation at our church. Bob and I had donated, and Bob ended up on the mailing list to receive the newsletter   with updates on the children. I hadn't read one since Bob died. But just three months before, in January 2012, the country had been hit by a terrible earthquake. In my depressed state, it hadn't even occurred to me to wonder whether the orphanage had survived. I opened the newsletter and was surprised to find out that My Father's House was still standing. Of course now it was more crowded than ever. At the bottom of the page was an announcement about an upcoming trip to visit the orphanage in person. "I should go." The thought wouldn't leave me. I contacted Carol Hawthorne."What would I do if I go?" I asked."Build houses?" "The Haitian people there are eager to work and they know what they're doing," said Carol. "What they need are raw materials, and we provide them. We also visit with the children. We go to clinics and schools, pass out supplies. You'll be very busy, I promise!" I reserved a seat but didn't mention it to any of my friends. Just a few weeks later, I was at the airport... The writer enjoyed herself at   _  . A) driving over the roads B) viewing the landscape C) seeing the expressions on children's faces D) observing water buckets on women's heads
