10、nBAt first, Michael Surrell didnt see the black smoke or flames shooting from the windows of his neighbors home. He and his wife had just parked the car when they got a call from one of his daughters: “The house next door is on fire!” He went to investigate. “The babys still in!” one of the women cr
11、ied. Though the fire department had been called, Surrell, aged 64, immediately ran inside. “The baby” was 8-year-old Tiara Roberts, the womans granddaughter. The thick smoke burned his eyes, and made it impossible to breathe. The conditions would have been harmful to anyone, but for Surrell, who has
12、 a lung disease, they were life-threatening.After a few minutes in the smoke-filled house, he ran outside to catch his breath. “Where is Tiara?” he asked desperately.“The second floor.” her aunt shouted back. Taking a deep breath, he went in a second time. Still unable to see, Surrell fell to his kn
13、ees on the hot wood floor, feeling around for any sign of the girl. Finally, he got Tiara who wasnt breathing. He fought through the smoke and ran blindly into the blackness. The next thing he knew, he was at the front door, then outside. Surrell put Tiara down and started CPR. Soon Tiara opened her
14、 eyes and took a breath on her own. Their eyes met. Surrell hugged her tight and said, “Uncles got you.” Soon after, his throat closed off. Surrell woke up in the hospital a couple of days later, having suffered severe burns to his windpipe and the upper portion of his lungs. As a result, he took ex
15、tra medication that helped open his airways. “Its a small price to pay,” he said. “Id do it again in no time and wont give it a second thought.”24.

18、fter seeing the dentist and can eat spicy chilies without any discomfort.She thought little of it until she sought treatment for an ankle problem at the age of 65. Doctors were astonished to find that she experienced no pain despite severe worsening in her ankle. A year later, she said she felt no p
19、ain after experiencing whats typically a very painful operation on her hand for osteoarthritis(关节炎). She doesnt take any medication and is fit and active, with no medical conditions apart from arthritis.Her doctors decided to analyze whether her lack of pain sensitivity was due to genetics and found
20、 it was caused by a mutation(突变) in a previously unidentified gene. Researchers found Cameron had two obvious mutations in her genetic makeup, one in the FAAH gene and another in what the scientists dubbed (复制)FAAH-OUT, which has been little studied by scientists.In a case study published Thursday,
21、researchers explained the discovery could help guide new treatments for a range of conditions, from post-operative pain to anxiety. The study said that Camerons mother and daughter appear to perceive pain normally. However, her late father had little need for painkillers, and her son reported having
22、 some degree of pain insensitivity, but not to the same extent as her. Now that we are uncovering how this newly identified gene works, we hope to make further progress on new treatment targets, Cox said. We need to learn from people who are suffering from pain but also those who are less sensitive
23、to pain, said Keogh, who is also the director at the universitys center for pain research.The implications of these findings are of great value, said Dr. Devjit Srivastava, who diagnosed Cameron.One out of two patients after surgery today still experiences severe pain, despite all advances in painki
24、ller medications, he added.The findings point towards a novel painkiller discovery that could potentially offer post-surgical pain relief and also accelerate wound healing. We hope this could help the 330 million patients who have surgery globally every year. 28. How did Cameron find she was lack of
25、 pain sensitivity?A. By seeing a dentist B. By eating chilies C. By seeking treatment D. By taking painkillers 29. What does the underlined world mean?A. understand B. feel C. know D. see 30. What can we conclude from what Keogh said? A. They are uncovering the secrets of mutation. B. They have made
26、 great progress in this gene. C. Their study merely focuses on the treatment targets D. More than one person is less sensitive to pain.31. From the view point of Dr. Devjit Srivastava , we can know_. A. The findings have discovered a new painkiller. B. Patients who have operations no longer suffer p
27、ain. C. The findings may be important to discover a new way to relieve pain. D. Most patients after surgery today still suffer great pain.DThe summer is so hot and sticky, why would we want to sweat even more by exercising? Or is it just me who thinks like that? Sweat and clothes sticking to our bod
28、ies as we move make exercise seem rather uncomfortable. What can be done to fix it? Researchers at MIT have come up with a solution. Theyve developed a workout suit with flaps that open as the wearer begins sweating. As the person cools off, the flaps shrink until they assume their original position
29、. Sounds cool, sounds practical. These flaps are lined with live, microbial (微生物的)cells. These cells can detect when the body is heating up too much, and in response, expand. Its just as if they were working within any other organism, recognizing patterns of heating and cooling, then responding appr
30、opriately to maintain body temperature. It seems kind of strange to have living cells (that arent your own) on you, right? Not to fear, these cells have been believed safe. Plus, theres a material in the suit that helps the flaps/cells hover ever so slightly above the exercisers skin. The flaps star
