It is closely linked to serious lung injury. H7N9 patients with higher levels of angiotensin carry more viral load (病毒载量), said Li Lanjuan, researcher at the Chinese Academy of Engineering and a specialist in H7N9 prevention. “It is particularly obvious in the second week of human infection. The angiotensin level of patients in critical condition keeps going up, while that of mild cases tends to drop，” Li said.Li added the new finding could help in clinical practice. Medical personnel could adopt more effective and reliable treatment measures for patients suffering different conditions. “This study will provide a new perspective to H7N9 pathology (病理) and potential treatment for future cases，” said Ed Gerstner, executive editor of Nature Communications.The study was led by researchers of the First Affiliated Hospital of Zhejiang University, Chinese Academy of Medical Sciences and Chinese Center for Disease Control and Prevention. They collected plasma from 47 H7N9 patients in cities of Hangzhou, Shanghai and Nanjing and analyzed the connection between angiotensin and viral load.H7N9 was first reported in China in March 2013. The virus causes severe disease in humans, including acute and often fatal breathing failure.语篇解读：本文是说明文。文章讲的是中国科学家发现了一种人体血浆蛋白与H7N9病死率有关。1What does the passage mainly talk about?AChinese scientists found a human blood protein associated with the H7N9 death rate.BChinese scientists have made a new medical discovery.CA new perspective to H7N9 pathology provided by a medical study.DA report of H7N9 death rate.解析：选A主旨大意题。纵观全文可知本文讲的是中国科学家发现了一种人体血浆蛋白与H7N9病死率有关，故选A。2The underlined word “critical” in the third paragraph most likely means _.AunimportantBmistakenCurgent Dsuccessful解析：选C词义猜测题。根据第三段最后一句话中的“in critical condition keeps going up, while that of mild cases tends to drop”可知critical condition与mild cases进行对比，故critical与mild意思应该相反，表示“危急的”，故选C。3According to the passage, which of the following statements is NOT true?AH7N9 patients with higher levels of angiotensin carry more viral load.BAngiotensin is a human protein to regulate blood pressure.CH7N9 virus may cause human breathing failure.DThe researchers collected plasma from 47 H7N9 patients in the city of Hangzhou and made the discovery.解析：选D细节理解题。根据倒数第二段最后一句话可知D项错误，故选D。4You can probably find this article in _.Aa booklet Ba newspaperCa guide book Dan advertisement解析：选B文章出处题。a booklet“小册子”； a newspaper“报纸”； a guide book“旅行指南”； an advertisement“广告”。根据文章内容可知本文是一则关于医学研究发现的新闻报道，应该在报纸上见到，故选B。.语法填空The “suspended coffee” project began in Italian cafs as a way to help the poor.The idea was for caf customers to buy an extra cup of coffee and reserve it for _1_ (that) who were unable to afford a hot drink.Since then it _2_ (gain) popularity in Europe, and now the idea has reached Shanghai.Chiato Coffee, _3_ operates in Pudong Library, began offering suspended coffee last Tuesday.On the first day, the shop sold 31 cups of the _4_ (reserve) coffee, but only four were drunk.The manager said the first customer for suspended coffee was a man in his 40s, who felt it was an _5_ (interest) idea and worth trying.Cao Jie, the cafs owner, says few people have taken up the offer _6_ they dont know about it.But she believes that the program will be very _7_ (practice) in China, and she hopes the concept can be spread to other businesses.Ma Lingling, a tea specialist
