The moment I was born, I seemed to be part of a set, as if my twin brother David and I were a package deal. We faced constant comparisons in our physical appearance. People were always comparing our personalities and academic performances as well! These constant comparisons made me decide not to go to the same university as my twin brother. That is not to say we didn’t have good academic experiences in the past or didn’t get along. In eleventh grade, we were placed in the same class. I recall arriving early to the first class and being a bit disappointed when I saw David already seated at his desk. It was hard to avoid comparisons when we were in the same class. However, we found that we actually worked well together, in our own way. We would argue about the best way to solve a problem and debate its answer. As the year went on, I noticed that our teacher kept moving us closer and closer together. Our argument was actually productive. However, we were two very different individuals. I was very involved in after-school activities, while David had better test scores than I did. I’m fond of writing while David enjoys playing computer games. I am currently studying English and French at McGill University, while David is studying computer science at Union College. Besides escaping comparisons, there have been other benefits to going to different universities. The first one is that we are forced to talk to each other, as we no longer see each other every day. This is healthier for our relationship. The second, also the more important one, is that after having so many similar experiences together we can have our own experiences separate from one another. Going to a different university has benefited me thus far. It allows for more personal growth, and I’m not attached to the label of being a twin. 【1】What did the author think about the constant comparisons? A.He was bored with them. B.He cared little about them. C.He tried his best to study them. D.He forced himself to accept them. 【2】What was beneficial when the author was in the same class with David? A.Strict teachers. B.Productive arguments. C.Performing in his own way. D.Classmates ignoring the twins. 【3】Why does the author think it a wise choice to go to a different university? A.He can escape arguing with David. B.He can avoid David in everyday life. C.He can be less dependent on David. D.He can pursue a personal experience. 【4】What question is the passage mainly intended to answer? A.Why did people like to compare me with my twin brother? B.What are the main benefits of being twin brothers at school? C.Why did I choose a different university with my twin brother? D.How can twin brothers get along well with each other at school? |

For the first time since local extinction in 1996, Nubian giraffes have returned to Pian Upe Wildlife Reserve in northeastern Uganda. Fifteen of this vitally endangered animals were moved over 400 km from Murchison Falls National Park in October 2019. The 11 female and 4 male giraffes are aged two to four: “We chose younger giraffes because they have a longer reproductive lifespan,” says Robert Aruho, a doctor of Uganda Wildlife Authority (UWA), who let the move. Northern Uganda is home to Nubian giraffes. They have large, rectangular blotches (矩形斑点) set irregularly against a cream background. The lower legs are noticeably white and not patterned. Pian Upe’s grassy land held large numbers of giraffes in the 1960s before conflict in the Karamoja region saw them hunted illegally. “The habitat is perfect, and effective anti-hunting measures are now capable of supporting at least 700 individuals,” explains Aruho. Nubian giraffes are Uganda’s only giraffe species and most of them inhabit Murchison Falls. “We can’t have all our eggs in one basket,” Aruho says, “We have a unique opportunity to act now to prevent them dying out.” Back in 2015, the UWA moved 15 Nubian giraffes from Murchison Falls to Lake Mburo National Park. After that, 9 of the 10 females quickly became pregnant. From a little over 300 Nubian giraffes in the mid 1990s in Uganda there are now about 1,650. A further 25 giraffes will move from Murchison to Pian Upe in October 2020. “In Uganda we continue to work closely with the UWA to increase numbers and populations of threatened Nubian giraffes. Boosting existing populations is vital for securing their future in the country,” Aruho says. 【1】Why were younger giraffes moved to Pian Upe Wildlife Reserve? A.They were in greater danger than the older. B.It was easier for them to adapt to a new habitat. C.They would reproduce more in future. D.It cost less to move younger giraffes there. 【2】Why did the author say “return” in Para. 1? A.The local didn’t support the movement at first. B.The giraffes used to live in Pian Upe in the 1960s. C.The giraffes’ habitats were built a long time ago. D.People moved all giraffes to escape local conflict. 【3】What is the original intention of the move according to Aruho? A.It’s better for giraffes to live in different places. B.700 giraffes is a point of what the reserve affords. C.Measures should be taken to stop local conflicts. D.Nubian giraffes look so attractive as to be hunted illegally. 【4】Which chart can describe the move of Nubian giraffes since 2015? P= Pian Upe L=Lake Mburo M= Murchison Falls A.  B. C.  D. |

A team of researchers at Brigham and Women’s Hospital, Harvard Medical School, has developed a system to use a smartphone camera to test for viral infections. In their paper published in the journal Science Advances, the group describes their system, which involves the use of an external microchip device and a smartphone system that uses a trained deep-learning algorithm. As the pandemic has gripped the world for most of this year, scientists have been looking for ways to slow the spread of the next one. In this new effort, the team has developed a smartphone-based system that can be used by non-medical people to test for a variety of viral infections. The system is made up of a smartphone, an external microchip device and software. Body fluid samples are placed into a channel on the microchip device, which is then dipped in a small amount of H2O2. The resulting reaction leads to the formation of bubbles. The bubbles develop in unique patterns based in part on viruses in the fluid sample. The user points their smartphone camera at the bubbling sample and starts the deep-learning algorithm that has already been trained to identify the patterns and therefore recognize the presence of viruses. The whole process takes about 50 minutes. The researchers have thus far taught their system to recognize just three viruses, Zika and Hepatitis B and C. But testing shows the system to be 99% accurate. They note that their system is more portable and cost-effective than other solutions in the works. The researchers suggest that their system could be rapidly trained to recognize new viruses if the need arises, and the microchip device could be sent to hot spots in the future. Such technology, the researchers suggest, could help to stop future pandemics if used widely. The researchers also note that the system could be immediately useful in infection prone areas lacking testing labs. 【1】What’s the purpose of the text? A.To advise people to use a new smartphone camera. B.To introduce the development of deep-learning algorithm. C.To explain the invention of a new microchip device. D.To show a new finding about testing for viral infections. 【2】Why did the researchers develop the new system? A.To educate ordinary people with medical skills. B.To help prevent the pandemic from spreading fast. C.To try to treat an illness with a smartphone camera. D.To make smartphones more portable and powerful. 【3】Which is the right working order of the system? ①Bubbles of a liquid sample are formed. ②Samples react with H2O2. ③Fluid samples are collected in a special device. ④Viruses in bubbles are recognized automatically. ⑤The software is started to examine the bubbles. A.③②①⑤④ B.③①②④⑤ C.②③①⑤④ D.②①③④⑤ 【4】What is the attitude of the researchers to the new system? A.Indifferent. B.Doubtful. C.Confident. D.Curious. |

How to stop mindlessly eating Are you trying to manage your weight or a health problem, but find yourself guzzling a bag of crisps?【1】 Put down the devices. It’s too common to chat through your phone as you have your meal, but it can make for mindless eating. Studies have found that we can put away as much as 25 per cent more calories if we concentrate on a phone, tablet or television at the same time. 【2】So eat at a table, preferably with a partner, friend or the whole family. 【3】 Do you tend to choose the prepackaged (包装食品), which are believed to be healthy foods like cereal bars and low-fat ready meals? These meals and snacks aren’t always as nutritious as you might think, even if they seem to be beneficial to your diet. Stop right there. 【4】And ask yourself whether you’re still hungry or close to being full. Are you enjoying the taste of what you’re eating, rather than just eating it up? I once went to a French wedding where the guests had six courses over six hours, with a break for entertainment between each one. I never felt full. There was something about the slow speed of the meal that made it more satisfying but less full. It takes around 20 minutes for your brain to realize that your stomach is full.【5】You’ll also enjoy your meal more. If you do find yourself overeating, stop and ask yourself if you are bored, worried or depressed. Once you identify the reason behind your mindless eating, you’re in a better position to put a stop to it. A.Know what you’re really hungry for. B.Here’s how to really focus on the right food in the right amounts. C.So if you eat more slowly, you tend to eat less and feel ready to eat again sooner. D.Be aware of the “healthy” choice. E.And when you’re dining out, simply be more interested in the food. F.To be really aware of the food you’re eating, stop halfway through your meal. G.Worse still, it is most likely that you eat more later in the day. |

阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。续写的词数应为150左右。 We were three thousand miles away from home on a Random Acts of Kindness and Volunteerism Road Trip. Our funds were running low, so we had two goals today. Firstly, try out our new “Smile!” signs and see how much kindness and joy we could spread. Secondly, raise a pitiful $20 a piece by doing street performances. Singing, drawing cartoons, storytelling… as long as it is enough for the trip to Portland. We weren’t sure how people would react to our signs. I nervously raised one up and shouted “Hi there!” to a young couple. They looked over, momently confused, then read my sign and broke into smiles. It worked. Before long, our signs were popular. Strangers stopped to ask us about them. The signs are more than an invitation to “Smile!”. They’re an excuse to connect with strangers and to remember this world is full of good people. We got so wrapped up in our “Smile!” project that we forgot our other goal. Before we knew it, the sun was setting, and we had no money for our trip to Portland. Then we noticed that a blind musician was playing guitar when suddenly a passing crowd kicked over his change jar. Change and cash scattered everywhere. Before we could run over, another man rushed to collect all the money for him. And we met the dogooder, Jared. “We want to praise you on your good deed,” I said. Jared looked at my signs curiously. We told him about our road trip, which reminded him of something similar he did when he was young. He seemed moved. |
