Transplant (移植) recipient John Bell knows exactly where to find his first heart-the damaged one he lived with for 72 years. It’s floating in a container of formaldehyde (福尔马林) at a large storage facility at Baylor University Medical Center, along with hundreds of other human hearts. When he returns to the hospital for a checkup with his cardiologist (心脏病专家), Bell expects to stop by to pay his old heart a visit. Why? Because at Baylor, he can do something almost no one else in the world has ever done. He can hold his heart in his hands. “It was fairly emotional, that first encounter,” says Bell. “I can’t actually explain why.” Bell is one of more than 70 heart-transplant patients who have participated in Baylor’s Heart-to-Heart program. It was launched in 2014 by William C. Roberts, MD. Baylor is unique in allowing transplant patients to “meet” their old hearts. “Probably 99.5 percent of hospitals throw the hearts away after they send out a report,” Dr. Roberts says. “We keep them all.” They are used for further research. The Heart-to-Heart program happened almost by accident. With all those organs stored on the hospital’s shelves, Dr. Roberts would sometimes take a curious patient to visit his or her old ticker. But the doctor discovered that the visits could provide a kind of teachable moment. “Many of the patients are overweight, and I show them the fat on the heart,” says Dr. Roberts. “Some people have so much fat on their hearts that they float in a container of water.” There’s a larger lesson too. “I try to stress to these people that they are very lucky. They are one of the few that get a heart,” he says. There are an estimated six million Americans living with heart failure, but only 2,000 to 3,000 receive hearts each year in the United States. 【小题1】Why does Bell want to visit his old heart? A. He intends to take it back home. B. He expects to observe and hold it. C. He wants to compare his with that of others. D. He thinks it is a good chance to learn about oneself. 【小题2】Which of the following is closest in meaning to the underlined word “ticker”？ A. Friend. B. Enemy. C. Heart. D. Part. 【小题3】It can be inferred from the last paragraph that . A. Dr. Roberts is an excellent teacher B. Most people are overweight in the U.S. C. The Heart-to-Heart program is important D. Hearts are in great need in the U.S. |

If you have flown with JetBlue or Delta airlines lately, you might recall a new program that allows passengers to board their flights with a facial recognition scan. However, you might not have known that these systems were also the first stage of the Department of Homeland Security’s (DHS) “Biometric Exit” program, which has been in place since June of last year, Slate reports. According to Slate, the DHS has partnered with Delta to make face recognition scans mandatory (强制的) for certain international flights leaving Atlanta and New York. DHS is also working with JetBlue to develop a similar system for travelers flying from Boston to Aruba. So, how does it work? Essentially, computers “match passport and visa photos of U.S. visa holders to photos taken at the airport from which they’re departing the country,” Mashable says. “This helps the U.S. make sure the people getting on the plane are the same people who hold those visas.” Still, the two programs are slightly different. The Delta system compares a photo of the passenger’s face, taken by a kiosk (信息服务亭) at the boarding gate, to photos from State Department databases. It also checks passengers’ citizenship or immigration (移民) status. If you’re flying with JetBlue, you can voluntarily get your face scanned instead of using a physical ticket. And these systems aren’t going away anytime soon; in fact, the program is expected to expand in the coming years. Homeland Security is currently negotiating to make face recognition a common feature across all American TSA security checkpoints, says U.S. Customs and Border Protection executive John Wagner. 【小题1】Who should go through the new security system? A. Passengers who fly from Boston to New York. B. All passengers entering the U.S. C. Passengers of certain international flights. D. All American passengers. 【小题2】What does “these new systems” refer to? A. The metal detectors. B. The airport security lines. C. TSA security checkpoints. D. The facial recognition systems. 【小题3】What can be inferred from the last paragraph? A. The two systems are to be perfected. B. There will be no privacy for passengers. C. JetBlue will be more efficient than Delta. D. More airlines will be involved in the program. 【小题4】For what purpose does the author write this passage? A. To warn travelers of the danger of taking certain flights. B. To inform traveler of the new program for some flights. C. To make a positive comment on the new systems. D. To protest against the new systems. |

We get used to how we smell, according to science. And it works both ways. Things that smell good begin to smell less good the longer we smell them, while things that smell bad tend to smell less bad over time. This trend toward neutral is known as “olfactory fatigue”(嗅觉疲劳). So then how is anyone supposed to know if they’ve got body odor (体味)? The answer is simple: If you’re capable of sweating, you should assume you’ve got B.O. That’s because virtually every human has sweat glands that produce chemicals that emit a scent when they interact with bacteria (细菌) that naturally occurs on the skin. In fact, it’s been estimated that only 2 percent of the population may not have to worry about body odor, at least under their arms, according to a 2013 study. The fact that you probably have armpits that produce a scent is not necessarily a bad thing. Our unique scents can make us seem more attractive to potential partners. And aspects of our personalities are revealed through our scents, although cosmetic use can affect assessments of others based on body odor. So the question really isn’t whether or not you have B.O., but how to get rid of body odor when it’s bad. The first line of defense against bad B.O. is, of course, a good regular cleansing, because “persistent body odor can be caused by poor hygiene,” says James Wantuck. “Poor hygiene leads to a buildup of bacteria on your skin, and those bacteria break down your sweat into malodorous (难闻的) chemicals causing the smell.” So, the obvious take-away is to keep your skin clean and fresh. What we put into our bodies affects our body odor as well. “We have all experienced the smell of excessive garlic intake.” Dr. Wantuck notes. 【小题1】Why do things that smell bad tend to smell less bad over time? A. The bad smell disappears gradually. B. We get accustomed to the smell. C. People try to get rid of the bad smell. D. We are too tired to notice the smell. 【小题2】What is the main cause of body odor? A. Sweat. B. Bacteria. C. Garlic intake. D. Unhealthy skin. 【小题3】Which of the following might be the best title for the passage? A. The Definition of Olfactory Fatigue. B. The Mystery of Body Odor. C. Body Odor and Health. D. Food and Body Odor. |
