New analysis of the arm bones of Lucy, an early hominid, suggests she was a tree climber. Lucy’s remains were uncovered in Ethiopia in the 1970s, with the 3.18 million-year-old skeleton(骨骼)being the most complete of any upright, walking human ancestor. Since she was discovered, researchers have debated whether she spent her life in the trees or spent time walking on the plains as well.The new evidence from scans of her arm bones proves she spent time climbing and used her arms to pull herself up. The scans were compared with cross sections of humans and chimpanzees, which spend a mixture of time in trees and walking on all fours on the ground. They found that the arm bones were more heavily built, similar to those of chimps, while her lower limbs(下肢)would have meant she walked less efficiently than modern humans. Professor John Kappelman, atUniversityofTexas, believes the advantage of his study was that it focused on characteristics that reflect actual behavior during life, suggesting that evenwhen Lucy walked upright, she may have done so less efficiently than modern humans, limiting her ability to walk long distances on the ground.Previous studies suggested that Lucy was just 4 feet tall and weighed just 65 pounds. Combining the new data paints a picture of an ancestor who may have spent a great amount of her time in trees. It also expands on evidence from earlier this year which claimed that Lucy may have died from a fall, most likely from a tree. The evidence suggests Lucy may have spent time on the ground, returning to the safety of the trees for food and to sleep, to avoid her enemies.4. What did the researchers argue about after Lucy was discovered?A. Where she lived.B. How long she lived.C. What she ate.D. How she worked.5. How could people tell Lucy spent time climbing?A. By her walking style.B. By her heavily built arm bones.C. By her strong lower limbs.D. By her large cross sections.6. When Lucy walked, she may________.A. have walked with bigger stepsB. have walked at a faster speedC. have walked more efficiently than usD. have walked a shorter distance than us7. What is the main idea of the last paragraph?A. Guesses about Lucy’s characteristics.B. Some evidence of Lucy’s health.C. The safety of Lucy.D. The ancestor of Lucy.CBack about 20 months ago I started college and just struggled with everything, such as classes and friends. I quickly became depressed and angry at myself for not being about to do better in school, in addition to lack of friends due to poor social and communication skills.This went on for months until my 19th birthday. My parents sent me a cake, which was a great cake. But I remember having this large cake and ly no one to share it with. I ended throwing out the cake after having one piece, with about 90 % of it leftover. That night I was depressed that I decided to go outside to the freezing temperature of the winter and run. I put my earphones in, went outside and ran about 2 miles at 11 p.m. on my birthday.When I got back inside I was content. I was proud of what I was able to do. The next night I did the same. I wasn’t quick or fit but you know that I went outside and did something. This continued for about 2 months until I finally worked up the courage to go to the gym, where I started swimming again as I used to in high school. A month went by and I started lifting weights and continually running.Looking back I can see that exercise helped cure my depression but it didn’t only do that. At the gym I met new friends and back at my dorm I grew confidence to go to the end of the hall seeing people playing Super Smash Brothers and ask if I could join.So go forward to present now. I exercise every day and look forward to that hour and a half I get daily to do what I love with people who love it as well. I hope this helps someone who may be or have been in a similar situation.8. What made the author decide to run at night?A. His l9th birthday.B. His parents’ cake.C. His loneliness.D. His friends.9. Which of the following best describes the author?A. Traditional.B. Determined.C. Humorous.D. Generous.10. What is the biggest benefit of the author’s running?A. Regaining his confidence.B. Losing his weight.C. Playing with his brothers.D. Joining other activities.11. Why do you think the author wrote this passage?A. To recall his life in college.B. To show his gratitude to his parents.C. To emphasize the importance of friendship.D. To share his experience of dealing with hardship.DTo show empathy is to identify with another’s feelings. It is to emotionally put yourself in the place of another. The ability to empathize is directly dependent on your ability to feel your own feelings and identify them.If you have never felt a certain feeling, it will be hard for you to understand how another person is feeling. If you have never put your hand in a flame, you will not know the pain of fire. If you have not experienced jealousy, you will not understand its power.Readingabout a feeling and intellectually knowing about it is very different than actually experiencing it for yourself.Among those with an equal level of emotional intelligence, the person who has actually experienced the widest range and variety of feelings — the great depths of depression and the heights of fulfillment, for example, — is the one who is most able to empathize. On the other hand, when we say that someone “can’t relate” to other people, it is likely because they haven’t experienced, acknowledged or accepted many feelings of their own.Once you have felt discriminated against, for example, it is much easier to relate with someone else who has been discriminated against. Our innate emotional intelligence gives us the ability to quickly recall those instances and form associations when we encounter discrimination again. We then can use the “reliving” of those emotions to guide our thinking and actions. This is one of the ways nature slowly evolves towards a higher level of survival.For this process to work, the first step is that we must be able to experience our own emotions. This means we must be open to them and not distract ourselves from them or try to numb ourselves from our feelings through drugs, alcohol, etc.Next, we need to become aware of what we are actually feeling — to acknowledge, identify, and accept our feelings. Only then can we empathize with others. That is one reason why it is important to work on your own emotional awareness and sensitivity — in other words, to be “in touch with” your feelings.12. How does the author explain the feelings of empathy?A. By giving examples.B. By having classification.C. By making comparison.D. By providing data.13. Which statement may the author agree with?A. Low level of empathy leads to fewer varieties of feelings.B. The deeper one’s feelings are, the more empathetic one is.C. Empathy is a way we recently picked up for better survival.D. Rich experiences may not go with a high level of empathy.14. What’s the purpose of the last two paragraphs of the text?A. To advise a sincere attitude to one’s experiences.B To suggest a right understanding of empathy.C. To require a realbond with one’s emotions.D. To call for true acceptance of one’s feelings.15. What is the best title for the text?A. How Empathy UnfoldsB. Be Open to Your EmotionsC. Why Is Empathy ImportantD. Accept Your True Self第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

导航卫星的原理就是不断地向地面播发导航电文，电文的核心内容就是位置坐标和相应位置的时间等信息。

为了实现信息足够高的精度，卫星本身要有非常精确的计时功能，这种计时功能是由原子钟来实现的。

原子钟是一种精密测量设备，它是利用某种元素原子的能级跃迁来实现精确计时的。

原子是由原子核及围绕它旋转的电子组成的。

有些原子拥有相当多数量的电子，分成不同的电子层。

当原子从某一个能量高的层次跃迁到低一点的能量层次时，它就会释放出电磁波。

某一种元素的原子，它的能级跃迁变化频率是固定的。

1956年，美国科学家生产出了实用化的原子钟，它所用的元素是金属铯。

铯有一个很大的优点，用它来制作原子钟非常方便。

铯的共振频率是9192631770赫兹，规定它的原子核振动这么多次所用的时间就是一秒钟。

随着技术的发展和进步，人们还开发出了用铷、氢元素作为原料的原子钟，体积越来越小。

目前最先进的成果是用金属铝来制造原子钟，精度比前三种原子钟都高。

北斗导航卫星携带了四台中国自行研制的高精度原子钟。

其中两台工作，两台备份。

原子钟之间相互校准，免得工作的那一台发生了超过设计指标的误差。

卫星在太空中围绕地球做圆周运动，飞行轨迹就是卫星轨道。

我们知道北斗星座是几个全球卫星导航系统当中轨道设置最复杂的，包括三种轨道类型，即地球静止轨道、地球倾斜同步轨道和中圆轨道，能够最大限度地给用户提供良好的服务。

卫星导航系统的工作主力是运行在中圆轨道上的卫星，它们在这个轨道上不断地向地面发射信号。

但是因为种种原因，包括宇宙射线、电离层和大气层的干扰，用户在使用中圆轨道卫星所提供的信号的时候多多少少会存在一定程度的误差。

为了尽量减小误差，就需要提供改正信息。

无论在GPS、格洛纳斯、还是伽利略系统的建设中，出于控制成本的考虑，都没有设置这样的轨道，改正信息是由第三方通过其他类型或者地面手段来实现的，而北斗卫星为了从一开始就尽最大努力来提高用户的信号精度，在系统设计当中就考虑了三种类型的轨道。

With many Americans tracking their stepsvia new fitness-tracking wearables, or even just by carrying their phone, more and more people use the 10,000-step rule as their marker for healthy living. Dr. Dreg Hager, professor of computer science at Johns Hopkins, decided to take a closer look at that 10,000-step rule, and he found that usingitas a standard may be doing more harm than good for many.“It turns out that in 1960 in Japan they figured out that the average Japanese man, when he walked 10,000 steps a day burned something like 3,000 calories and that is what they thought the average person should consume so they picked 10,000 steps as a number” Hager said.According to Hager, asking everyone to shoot for 10,000 steps each day could be harmful to the elderly or those with medical conditions, making it unwise for them to jump into that level of exercise, even if it's walking. The bottom line is that 10,000 steps may be too many for some and too few for others. He also noted that those with shorter legs have an easier time hitting the 10,000-step goal because they have to take more steps than people with longer legs to cover the distance. It seems that 10,000 steps may be suitable for the latter.A more recent study focused on older women and how many steps can help maintain good health and promote longevity (长寿).The study included nearly 17,000 women with an average age of 72. Researchers found that women who took 4,400 steps per day were about 40% less likely to die during a follow-up period of just over four years: Interestingly, women in the study who walked more than 7,500 steps each day got no extra boost in longevity.4. What does the underlined word "it' in Paragraph 1 refer to?A. The phone recording.B. The 10,000-step rule.C. The healthy living.D. The fitness-tracking method.5. What does Paragraph 2 mainly talk about?A. How many steps a Japanese walks.B. How we calculate the number of steps.C. If burning 3,000 calories daily is scientific.D. Where 10,000 steps a day came from.6. Who will probably benefit from 10,000 steps each day according toHager?A. Senior citizens.B. Young short-legged people.C. Healthy long-legged peopleD. Weak individuals.7. How many steps may the researchers suggest senior citizens take each day?A. 4,400 steps.B. 10,000 steps.C. 2,700 steps.D. 7,500 steps.CThe world's largest iceberg is floating toward South Georgia in the southernAtlantic Ocean. Scientists fear the iceberg could crash into the island and block major feeding areas for a large population of penguins and seals. If the iceberg hits the island, it could prevent the penguins and seals from reaching food supplies.The huge iceberg is named A68a. It broke away fromAntarctica's Larsen C Ice Shelf in 2017. Satellite images show the iceberg has remained in one piece. It is estimated to be about 150 kilometers long and 48 kilometers wide. It is traveling at one kilometer per hour and is on a path to hitSouth Georgiain around 30 days.This is the time of year when seals and penguins spend a lot of time caring for their young. The distance that parents have to travel to find food is crucial. That means they have to go a lot further or go around the iceberg to find sources of food.Ecologists say an iceberg crash would also disturb materials settled on the seabed, possibly polluting the surrounding seas. As the iceberg melts, it would also release large amounts of fresh water into the ocean. This could affect krill（磷虾）populations that are a major source of food for the island's wildlife. The iceberg could remain for up to 10 years and change the area's whole ecosystem. These are globally significant populations of these species. If these species fail in this particular area, then the numbers globally are going to go down quite dramatically.Professor Geraint Tarling, an ecologist at the British Antarctic Survey, said, "The breaking off of icebergs fromAntarcticais a natural process. But the process is changing with climate change. What we're seeing with models and some observations now is that this is happening at an increasing rate. And so, this might become more of a usual thing in the future."8. Why are the scientists worried about the coming iceberg crash?A. It will bring extremely cold weather.B. It will destroy the feeding areas of the animals.C. It will put wildlife on the island at risk of starving.D. It will prevent animals from moving to other places.9. What is paragraph 2 mainly about?A. The characteristic of the iceberg.B. The importance of the iceberg.C. The traveling speed of the iceberg.D. The forming process of the iceberg.10. What damage can an iceberg crash bring according to paragraph 4?A. Using up much fresh water.B. Polluting the surrounding farms.C. Changing the world's ecosystem.D. Affecting the number of certain species.11. How does Tarling think of the breaking off of icebergs fromAntarctica?A. It may slow down in the near future.B. It may become common in the future.C. It has a great influence on the climate.D. It helps scientists conduct a sea study.DImagine the feeling of swinging at a baseball going 100 miles per hour—without leaving your living room, or being in race car as it roars down the track, while you are sitting on the couch.These are just some of the ways that sports business leaders say virtual reality (VR) will revolutionize how people train for and experience sports. Virtual and augmented（增强的）realities are together known as mixed reality (MR). “American footballers are already using VR to better train their minds andread the field,” Ludden said. “This can allow players to perfect their skills without risking injury.”Canadian company D-BOX Technologies designs and produces moving seats found in cinema and theme parks. It is now moving into sports, and shows its Formula One (F1) racing simulator（模拟器）. The seats stimulate the force of gravity, speed and every shaking as Fl champion Lewis Hamilton zips around city streets.A simulation seat uses pre-programed data now. Someday, though, it could use real-time information sent by the car. “They couldbroadcast live content through a network in pop-up theaters around the world,” Ludden said. Say you want to experience the true stress of a batter being up against major-league baseball pitcher. “You can have a heartbeat added to the sensation on the seat and then you can feel it, boom, boom,” Maheu explained. “When he swings and hits the ball, you can have an impact.”One day, fans around the world could physically experience every game from their favorite player in real time. Ludden said that current and near-future technology could create “augmented stadiums” for live audiences. Panasonic launched its “Smart Venue” plans which included the overlaying of graphics, advertisements, player statistics and replays on the field of play at a pro football game. “If you are seated in the cheap seats, you can see this really useful.” “Fans may someday join in stadium wide games, using the field as a virtual gaming platform,” Ludden added.12. What does the underlined phrase “read the field” in paragraph 2 mean?A. Get off the playing field.B. Build up a football court.C. Judge the situation on the field.D. Ask players to play on the spot.13. What does Maheu think audiences can do in the future baseball game?A. Enjoy live content in any theater.B. Program the simulation seats in advance.C. Control the force and speed of the baseball.D. Experience the real time game with the player.14. What does Ludden mainly describe in the last paragraph?A. The origin of VR.B. A future stadium.C. An advertisement platform.D. The expectations of audiences.15. What is the main idea of the text?A. VR can improve players' skills for sports.B. VR increases fans' joy in the baseball game.C. VR can improve sports experience for players and fans.D. VR promises a new future for football players and games.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

Crowds celebrate with viewing parties,flockingto the most popular locations to take photos and have picnics underneath the branches.But this year, cherry blossom season has come and gone in the blink of an eye, in one of the earliest blooms on record. Scientists warn it’s a symptom of the larger climate crisis threatening ecosystems everywhere.Yasuyuki Aono, a researcher atOsakaPrefectureUniversity, has gathered records fromKyotoback to 812 AD from historical documents and diaries. In the central city ofKyoto, cherry blossoms peaked on March 26, the earliest in more than 1,200 years, Aono said. And in the capitalTokyo, cherry blossoms reached full bloom on March 22, the second-earliest date on record.The peak bloom dates shift every year, depending on numerous factors including weather and rainfall, but have shown a general trend of moving earlier and earlier. InKyoto, the peak date stayed around mid-April for centuries, but began moving into early April during the 1800s. The date has only dipped into late March a handful of times in recorded history.“Sakura blooms are very temperature sensitive,” said Aono. “Flowering and full bloom could be earlier or later depending on the temperature alone,” he said. “The temperature was low in the 1820s, but it has risen by about 3.5 degrees Celsius to this day.”This year’s seasons in particular influenced the blossom dates, he added. The winter was very cold, but the spring came fast and unusually warm.4. What is the best title of the passage?A. Cherry blossom celebrations.B. Warning of a climate crisis.C.

It can help you manage weight, keep blood sugar levels down and reduce risk factors for heart disease.Now, a new study suggests that regularly playing sports, especially badminton or tennis, is not only healthy but also reduces your risk of death, at any age, by approximately 50%. This is a big scale population study to explore the health benefits of sports in terms of death rate. The study evaluated responses from 80, 306 adults aged 30 and above inEnglandandScotland, who were surveyed about their health, lifestyle and exercise patterns.After adjusting factors such as age, sex, weight, smoking habits, alcohol use, education and other forms of exercise besidesthe named sports, the researchers compared the risk of death among people who took part in a sport to those who didn’t. The percentage of reduced risk of death was found to be: 47% for racket（球拍）sports, 28% for swimming and 15% for cycling.In addition to this, the study didn’t find any significant reduction in the risk for sports like running and football. The findings also exposed that over 44% of the participants met the guidelines for the recommended exercise levels to stay fit and healthy, which amounts to 150 minutes of moderate(适度的) physical activity in a week.Does this mean you stop running or playing football and switch to tennis instead? Every kind of sport and physical activity has different physical, social and mental benefits attached to it. The apparent lack of benefits of running and football could result from several variables that were not taken into account.Being active helps you feel happier and live longer. So, the most important step is to take part in any kind of sport that you are likely to enjoy and follow in the long term.8. How is the study conducted?A. By doing comparative experiments.B.

The US government has long viewed globally competitive Chinese high-tech companies including Huawei as a threat and done whatever it could to crack down on（打击）them in the name of “national security”.The US government has not introduced any specific policy against TikTok only threatened it through a number of unclear statements.According to the latest media reports, Microsoft is prepared to press ahead withthe negotiations to take over TikTok’s US operations and complete the negotiations by Sept 15, following talks between Microsoft CEO Satya Nadella and US President Donald Trump.This means that TikTok will have to hand its fate over to some unpredictable power, and even have to sell its assets without the option of setting a price.The US government has failed to find a reasonable legal excuse to deal with TikTok. All private data of TikTok’sUS users are stored in the US and are unlikely to be transferred. Considering the US government is trying to deal with TikTok in a political way, TikTok should consider incorporating（合并）the dispute into the US legal process to assert（坚持）its legal rights and interests.TiKTok’s core value lies in its unique algorithms,a product of artificial intelligence that represents the expertise of Chinese engineers and programmers with high-value intellectual property.The US government’s move, which has forced ByteDance to sell TikTok to a US company, is similar to a forced technology transfer and an example of the US’ openseizureof Chinese intellectual property.If ByteDance sells TikTok to a US company for “security reasons", that would set a dangerous precedent, motivating other countries where TikTok operates to follow the US administration's example and cause a chain reaction.ByteDance is a young Chinese private company that cannot deal with a political game played by the US. But as a Chinese company that has gone global, ByteDance has reasons to take up legal means to defend its legal rights. The Chinese government can also consider examining whether the technology transfer in the deal violates China’s law and harms the country’s national interests.12. What is the most valuable as for TikTok?A. Its global popularity.B. Its artificial intelligence.C. Its registered global mobile internet app.D. Its private data of TikTok’s worldwide users.13. Why does the American government force the Chinese company to hand over TikTok’s US operations to a US company?A. Out of so-called political reasons.B. Out of so-called debt reasons.C. Out of so-called technical reasons.D. Out of so-called security reasons.14. What does the underlined word “seizure”probably mean in Para. 8?A. An untrue spoken statement about someone.B. The use of legal authority to take sth from sb.C. The crime of stealing sth from a person or place.D. The act of trying to hurt somebody using physical violence.15. What can be the best title for the news report?A. TikTok must defend its rights legallyB. TikTok is seen as a threat to FacebookC. ByteDance has to sell TikTok to a US companyD.
