A new study that followed a chimpanzee community in the forests of Uganda has found that quality time with close companions significantly decreased stress hormone levels in the primates whether they were resting, grooming or facing off against rival groups.The findings, described this week in the journal Nature Communications, shed light on the physiological effects of close companionship on chimpanzees and could have implications for human health too.Researchers have long known that stress can worsen health and raise the risk of early death in humans as well as other social mammals. “It can have effects on immune function, cardio function, fertility, cognition, and even your mood，” said study coauthor Kevin Langergraber, a primatologist at Arizona State University.Maintaining close social bonds can help these animals (humans included) reduce some of that stress, potentially minimizing some health risks. But scientists have yet to pin down the exact physiological mechanisms at work.“Social bonds make you survive and produce better but how do they do that？” Langergraber said.To find out, the international team of researchers studied members of the Sonso chimpanzee community in Ugandas Budongo Forest, a group consisting of 15 males, 35 females and 28 juveniles and infants during the study period from February 2008 to July 2010.Like humans, chimpanzees tend to have besties bond partners with whom they appear to feel close. The researchers wanted to see whether interactions with these bond partners led to lower stress levels during particularly stressful situations, such as when fighting rival groups, or whether time spent with friends helped lower stress levels more generally, throughout the day.The scientists observed the chimpanzees perform three types of activities: resting, grooming or quarrelling with other groups of chimpanzees. The researchers kept track of whether the chimpanzees were doing any of these three things with their bond partners or with other chimpanzees in their group.A team of up to six observers watched the chimpanzees and followed them around to collect urine (尿液) samples. The samples, collected from nine adult male and eight adult female chimpanzees, were tested to see how much of the stress hormone cortisol they contained.The scientists found that chimpanzees levels of urinary cortisol were 23% lower, on average, during the activities when they were with their bond partner. This was especially true for stressful activities, such as the intergroup rivalries, where any chimpanzee on the front line might face physical harm or even death.The findings in chimpanzees, some of our closest living relatives, could shed light on the role such close social relationships play in human health too, he said. Such friendships may be just as important during good times as bad though more research needs to be done before any conclusions can be drawn.“This has interest for a lot of people in a medical context as well，” Langergraber said.1The scientists carried out research into a chimpanzee community in Uganda _.Ato seek evidence of benefits of social bonds from physiological anglesBto uncover whether social bonds make humans surviveCto study how chimpanzees perform three types of activitiesDto train chimpanzees to maintain close social bonds with each other解析：选A推理判断题。根据第五至七段内容可推断，科学家们对黑猩猩群落进行研究是为了从生理角度寻求能证明社会关系的益处的证据。故选A项。2.What does the underlined word “they” in Paragraph 10 refer to?AObservers.BChimpanzees.CUrine samples.

He has been working as a custodian (管理员) there for the last eight years, cleaning the floors, vacuuming the carpets, wiping the blackboards and picking up the trash. But last month, Michael picked up something he really wants to obtain all his life a degree in mechanical engineering.In the year 2008, Michael, a businessman, with two decades of successful business, felt his world crashing down around him. Fewer phone calls were coming in, but he tried not to panic. Then customers stopped calling completely and he had no choice but to apply for bankruptcy. Soon, his home was foreclosed (取消抵押品赎回权). And without his income to support his wife, her vending machine (自动售货机) business eventually went under as well. He and his family had to move from their big house to a tiny apartment. Michael started looking for jobs with construction companies, but no one had the intention to hire a man in his age.The only work he could find was to be a custodian at a local college.The pay was about half what he used to make, but the benefits were good, so he told himself that he would take advantage of the benefits offered by the school, to feel like he was making more money. One of the added job benefits was tuitionfree classes, so he decided to make good use of them as well. Michael would take the classes by day and clean up after his schoolmates at night. “I was angry. I was depressed. But as the semester went on, I thought, Oh geez, this is taking my mind away from everything，” the happy graduate said. “When I got my first A, I thought, This is really nice.”But it didnt all go smoothly. His new job wasnt something that he was especially proud of. Besides, the failure of his business still crowded his mind, which challenged him most. “When you lose everything like that, you dont trust your ambition. Youre just trying to get through the day，” Michael said. “It was hard to look my kids in the eye. I couldnt tell them to work hard and theyd be successful . because I did that, and I lost.”In spite of the hardships Michael had to go through, he kept going to classes, and after three years into his studies he realized he was well on his way to a college degree. He felt awkward attending school along with students at his kids age, but the support of the other students turned out to be a big factor in his unbelievable achievement. “I realized it was more my own judgment than anyone elses，” he said.“They thought what I was doing was really great.”On May 14, 2016, eight years after taking his first class at WPI, Michael walked out on the stage to pick up his diploma, under the proud eyes of his family and colleagues. He continued to work as a custodian at WPI, but he was also looking forward to the day when he could pick up a job in engineering. On the big day, Michael wrote “OLD DOG HAS NEW TRICKS” on the top of his mortarboard (学位帽), and on each corner inscribed a single letter: a “J” for Joyce, his wife; a “P” for Paul, his son; and an “A” and “N” for Amanda and Nicole, his daughters a perfect gift to his supportive family.Michaels ambition and insistence have inspired the entire custodial staff at WPI. Over the years, other members of the staff had attended the free classes offered by the school like him, but none of them could achieve their goals to the extent he did. “When people say my story inspires them, I know what that means on the other side. From time to time, other peoples stories got me through unpleasant times. Im glad I can be that person，”Michael said.语篇解读：本文是一篇记叙文。迈克尔生意失败后到Worcester Polytechnic Institute当管理员。他一边工作一边学习。八年之后，持之以恒的他获得了机械工程学位。5What happened to Michael in 2008?AHe failed in his business.BHe was cheated by his partner.CHe was divorced for lack of money.DHe launched a vending machine business.解析：选A细节理解题。从第二段的内容可知，2008年，迈克尔的客户越来越少，他生意失败，不得不申请破产。故选A项。6What was the biggest challenge facing Michael as a custodian?AHe couldnt get the pay he expected.BHe had difficulty coping with schoolwork.CHe couldnt set a good example to his kids.DHe couldnt get out of the shadow of failure.解析：选D细节理解题。根据第四段的“the failure of his business still crowded his mind, which challenged him most”可知，他一直无法走出生意失败的阴影，这是他面临的最大难题。故选D项。7.What does the underlined word “it” in Paragraph 5 refer to?AMichaels achievement in getting a college degree.BMichaels embarrassment of being an old student.CThe difficulty Michael went through.DThe support of other students.解析：选B代词指代题。从第五段的“He felt awkward attending school along with students at his kids age，but the support of the other students turned out to be a big factor in his unbelievable achievement.”可知，迈克尔觉得与他的孩子们同龄的学生一起上学很尴尬，但是其他同学的支持结果证明是他取得令人难以置信的成就的一个重大因素。由此可推知，画线词所在句指的应是迈克尔意识到他作为一个年龄较大的学生去上学的尴尬是他自己的判断，而不是其他人的看法。故选B项。8What did Michael do after obtaining the degree?AHe worked as an engineer.BHe stayed at the previous post.CHe got a teaching position at WPI.DHe devoted himself to further study.解析：选B细节理解题。根据第六段的“He continued to work as a custodian at WPI, but he was also looking forward to the day when he could pick up a job in engineering.”可知，迈克尔继续在WPI当管理员，但是他也盼望着有一天能够得到一份与工程学有关的工作。故选B项。9What did Michael really want to say in the last paragraph?ASome time should be spent in reading inspiring stories.BPeople should understand the true meaning of success.COnes inspiring stories can be of great value to others.DThere is no need for his colleagues to follow him.解析：选C推理判断题。人们称迈克尔的故事能激励他们，而有时，人们的故事也会使迈克尔度过不愉快的时期。由此可知，迈克尔想说的是一个人的鼓舞人心的故事对其他人有很大的作用。故答案选C项。10What can we learn from Michaels story?AEveryone has their price.BThere is no time like the present.CThe grass is greener on the other side.DNothing is impossible for a willing heart.解析：选D推理判断题。根据文章的内容可知，尽管迈克尔生意失败，但在他找到新的工作后，他一边工作一边学习。八年之后，持之以恒的他获得了机械工程学位。故选D项，表示“心之所愿，无所不能”。A项意为“重赏之下，必有勇夫”；B项意为“机不可失，时不再来”；C项意为“草是那边绿；这山望着那山高”。C(2017江苏省六市高三联考)HIV is a tricky virus that escapes typical immune responses. During a successful immune system response to a foreign body, white blood cells produce antibodies that target the foreign body. These antibodies then mark the foreign body for destruction by other immune cells. For the most part, HIV escapes these immune defenses, but rare individuals develop antibodies that effectively block the virus. Researchers are now showing that these antibodies can also act as treatments in other HIV patients. HIV has several ways of escaping the immune response. Unlike most viruses, HIV specifically attacks a type of white blood cell that is critical to our immune system. During reproduction, the HIV virus also picks up many new mutations (变异), which often change it enough that any antibodies produced earlier during the infection no longer recognize it. These rare antibodies can also keep the virus from infecting new cells, which could make them an effective treatment. In animal studies, injection of low concentrations of these antibodies could act as a vaccine (疫苗) and provide protection against infection.Injections can even control active infections when combined with additional antibodies that target other molecules (分子) on the HIV surface. These findings led to humans phase 1 clinical trials to evaluate a specific antibody that targets HIV. This study revealed that a single injection of the antibody typically reduced the presence of HIV in the blood of patients who have viruses that were sensitive to the antibody.After performing testtube studies showing the effectiveness of the antibody, the researchers evaluated its safety in humans in a small trial. The study included two groups of participants: 14 uninfected individuals and 19 individuals with an HIV1 infection. The researchers then tracked the clearance of the antibody by following its levels in the participants blood.Consistent with previous studies, HIV1 infected individuals exhibited faster clearance of the antibody, with a halflife of 12.8 days compared to 24.0 days for uninfected participants.Despite the fast clearance, however, the antibody appeared to be effective. Thirteen HIV1 infected participants with the highest levels of virus received the highest dose (剂量) of the antibody. Eleven of them showed a rapid decline in HIV levels. Tracking the infection through the first weeks after treatment revealed the evolution of multiple viruses that were no longer affected by the antibody. However, these new variants (变体) generally remained sensitive to antibodies targeting ot
