Please listen to a story of the dodo and how it disappeared from the earth.二•阅读理解ALittle did I know that the boy I knew in middle school was depressed （抑郁的）. Never did it occur to me that he had just missed the knock of death.It all happened before a biology class, when my friend sitting next to me asked if I knew what had happened to Jack the night before. I said no. She then pulled up her Facebook page in her mobile phone, and showed me Jack，s post: he stole his brother^ car and crashed （撞）it against the wall on the highway一on purpose.In America, whatever is posted on Facebook is for everyone to talk about, and today's topic, of course, was about Jack. To me, however, I felt a responsibility to achieve. As an editor of my high schooPs newspaper, I thought it was my duty to cover what had happened. I would use this power to spread the awareness of depression （抑郁症）.I began to write my article. I researched into depression. I collected real life stories. At first I was afraid that it would be difficult to interview the students who were suffering from depression, but they reached out to me, and gave me in-depth answers. They described how bad they might feel and what they would suddenly feel like doing一however terrible it could be.I also managed to speak to Jack. It was a bit embarrassing at the beginning, because the air around seemed to be still. Finally, I cut through the silence by asking directly: "How did this all start?^^While writing the article, I was serious- The stories and the feelings I had learned from my schoolmates were too much to me. However, I knew this article was going to change lives.1.What did Jack do the night before the writer knew it?A.He was caught stealing a car.B. He almost killed himself.C. He put on a live show on Facebook.D. He suddenly fell seriously ilk2.What responsibility did the writer feel?A.To raise public awareness of depression.B.To run a special newspaper on depression.C.To find better treatments for depression.D.To use his power to spread more happiness.3.The writer did a lot to achieve his responsibility EXCEPT _____ .A.doing careful research into the illnessB. telling people how to cure the illnessC. collecting real life stories from sufferersD. writing an article about the illnessBOrganic （有机的）foods have had a pretty good rise in popularity over the course of the last decade. And it seems that in the near future the trend will steadily continue. From 2004 to 2014, American organic food production increased by 240%. Natural and organic sales reached $81.3 billion in 2014, up 13.5% from the year before.It seems like everywhere you go, you see organic products. However, is this trend actually a good thing? Are the benefits of organic foods grounded in scientific fact?The sign "Organic"is given to products by the United States Department of Agriculture （USDA）. The foods with the sign have to maintain a certain standard of production. For example, the food should not be grown or raised using any pesticides （杀虫齐ll）or fertilizers （化I］巴）.Probably the major reason why people are encouraged to buy organic foods is that they are told: “Organic foods are better for you.”But is this really the case?According to some studies, although organic foods have higher levels of vitamin C and minerals （矿物质），the differences are little ― these may have no influence on the overall nutrition （营养）.Besides, there's really very limited information on actual health outcomes with eating these products. Comparing organic foods and those produced in traditional ways, we don't know enough to say which is better than the other.But these studies have not provided any final say on either of them. If anything,it's only added fuel to the heated debate over whether organic products are really worthy of their popularity and prices.4.What's the trend discussed in the article?anic foods are getting more and more welcomed.anic foods are winning popularity in most countries.C.Foods produced in traditional ways are dying away.D.The ways of producing foods will be more scientific.5.WhaFs true about organic foods according to some studies?anic foods only sound healthie匚B.People get healthier by eating organic foods.C.They are different in outcomes from other foods.D.They have the highest levels of overall nutrition.6.What can we know from the last paragraph?A.The studies lead to more discussions about organic foods.B.The studies provide clear advice on what food to choose.anic foods dorf t deserve such popularity and prices.anic foods will lose ground to other kinds of food.7.What is the articled attitude towards organic foods?A.
