Earth's core is about as hot as the surface of the Sun, so hot that it melts the rocky layers above it into magma, or liquid rock. Wouldn't it be great if we could tap into all that energy? In some places, we do!The Geysers is an area north of San Francisco in California where magma's heat turns a reservoir of underground water into steam. This region is home to 18 geothermal power plants. The steam rises up through spaces between the rocks underground, a bit like how steam pours from a teakettle boiling on a stove. The power plant has pipelines that send the steam into the turbines (涡轮机) where electricity flow is generated. Once the steam leaves the turbine, it goes into a cooling tower where it turns back into liquid. Then it's piped back into the reservoir to be reheated again. Other kinds of geothermal power plants pump hot groundwater into the power plant. Then thepressure is reduced, causing the liquid to flash into steam that turns the turbine and generates electricity flow. Once the steam cools and turns back into liquid, it's pumped back down into the reservoir to begin the cycle again.So why don't we all heat our homes with free steam from the earth? First, the heat has to be close enough to the surface for us to reach it. Next, there has to be plenty of underground water to be heated. Finally, there has to be a layer of rock that water or steam can flow through. So in places where all three of those things come together, geothermal energy can be a powerful renewable energy source. Besides, when a geothermal plant returns water back into the hot rocks of a reservoir, it makes the rock crack a bit, which can cause small earthquakes. There's another danger that comes with drilling near magma-pipes and other equipment might melt if they hit a pocket of magma or are caught in an eruption. One geothermal plant in Hawaii was partially buried by lava in 2018. But engineers are hopeful that the repaired plant will generate even more power. Geothermal energy isn't the answer for everywhere, but it's a piece of the puzzle to help slow climate change.2.In which part of power plants is the electricity made?A. The turbine.B. The reservoir.C. The pipeline.D. The tower.3.What prevents free steam from being widely developed according to paragraph 3?A. Hard surface and possible earthquakes.B. Changeable climate and unqualified equipment.C. Limited underground water and thin layers of rock.D. Unsuitable geological conditions and potential dangers.4.Why is the buried geothermal plant in Hawaii mentioned?A. To demonstrate the great effort that engineers made.B. To show the power that the repaired plant can generate.C. To illustrate the danger caused by drilling near magma.D. To praise the engineers who repaired the generate plant.5.What is the author's attitude towards geothermal energy?A. Unconcerned.B. Unclear.C. Doubtful.D. Approving.BBiological fieldwork can mean trips to exotic places. The most common method is to send a few eager graduate students armed with camera traps and several weeks of spare time. But perhaps not for much longer. A paper published in Current Biology suggests an easier method: simply swabbing(擦拭) nearby leaves for DNA.The DNA in question is called "environmental DNA" (eDNA for short). It refers to all the genetic information that animals leave behind as they go about their daily business: breathing, urinating, or interacting with their environment in any way. In recent years, genesequencing(基因测序) technology has become quick and sensitive enough to pick out genetic sequences from particular animals including humans from this eDNA.One way of doing so is simply to blow air through filters(过滤器), and then analyse them to see which animals live nearby. Drs Gogarten and Lynggaard wondered if there might be a simpler approach. Air-sampling systems can take days to do their work. Maintenance must be done, and filters must be changed. But given that eDNA is literally blowing around ecosystems, the searchers wondered if it might be collecting on leaves.The leaves of many plants are waxy(蜡质的) and somewhat sticky. The researchers theorised that eDNA might end up stuck to leaves and that it could subsequently be collected by swabbing them. They tested their theory in the dense rain forests of Kibale National Park, in Uganda. Using simple cotton swabs, and wearing masks and gloves to prevent polluting the samples with their own DNA, they visited three areas of the park and collected eight swabs at each site, and then took them back to Copenhagen for analysis.The swabs revealed the presence of 26 birds, 24 mammals, one amphibian and one fish, with each swab containing DNA from eight animals on average. More than half the samples were good enough to work out the precise species they came from.Swabbing for animals, then, seems to work. Moreover, it is cheap, easy and fast. Graduate students will have to be content spending less time sample-hunting in distant parts of the world.6.Who will benefit most from the research findings?A. Forest farmers.B. Biological graduates.C. Ambitious scientists.D. Environmental activists.7.Why was the researchers armed with masks and gloves?A. To protect the leaves.B. To avoid getting stuck.C. To stay safe from wax.D. To ensure the quality of samples.8.How is eDNA method compared with the common ways?A. More animal-friendly.B. Free of complex analysis.C. More accurate and effective.D. Economical in time and money.9.What serves as the best title for the text?A. Swabbing leaves: an easier method to track animalsB. Testing eDNA: a useful tool for animal detectionC. What the function of leaves isD. How the field work goesCBegin your global journeyAt University of Wisconsin (UW) -Eau Claire, you'll find your investment pays off well before you graduate.

Automated voice son phones and machines suck the contact and relational element out of day-to-day life, so much so that experts say that we are experiencing a loneliness disease.According to Dr. Lalitaa, loneliness is the feeling we get when our need for rewarding social contact and relationships is not met. But loneliness is not always the same as being alone. Loneliness is a state of mind linked to wanting human contact but feeling alone. People can be alone and not feel lonely, or they can have contact with people and still experience feelings of loneliness.Loneliness is a universal human emotion that is both complex and unique to each individual. There are many contributing factors to loneliness, such as illness, relationships breaking down, moving country, changing jobs ornot being understood by co-workers, retiring, starting university, etc.We cannot underestimate the impact loneliness can have on our physical and mental wellbeing. According to research, loneliness has comparable health risks to smoking 15cigarettes a day, and people who feel lonely are more likely to die earlier and suffer from heart attacks. Dr. Lalitaa says, "People often say to me, 'It's too late to meet new people as an adult.' Having human connect ion can look different for each person, but this can become a block, stopping them going out, trying new things and connecting with new people. Remember, it is never too late to make good, meaningful connections."However, don't put pressure on yourself. A meaningful relationship takes time. It is not just created overnight. Also, take some time to sit with yourself and venture(冒险) into some of the things that you like doing. "The first thing I would say is not to deny or distance the feeling. Acknowledge it and then you can choose to focus on ways to help yourself," says Dr. Lalitaa.13.How does the author clarify what loneliness is?A. By stating arguments.B. By giving examples.C. By making comparisons.D. By employing figures.14.Why is smoking cigarettes mentioned in the text?A. To explain the causes of loneliness.B. To illustrate the harm from loneliness.C. To overestimate the impact of loneliness.D. To emphasize the universality of loneliness.15.What does the underlined word "this" in paragraph 4 refer to?A. Lack of appealing reward.B. Dependence on the network.C. The regret for the passing youth.D. The idea of being too late for new relations.16.What does Dr. Lalitaa consider as priority when dealing with loneliness?A. Having new experience.B. Telling it from being alone.C. Being aware of and recognizing it.D. Making friends from all walks of life.EThere is a festival in China that has three names. Itˈs known as the Chongyang Festival. Also, it is called the Double Ninth Festival because it falls on the ninth day of the ninth month of the Chinese lunar calendar (阴历). Finally it has been Seniorˈs Day (老人节) since 1989. This year, it fell on Oct 23rd.There are many traditions for this festival. In the past, people climbed mountains, drank chrysanthemum (菊花) wine, and wore a plant called zhuyu to celebrate it. Climbing mountains in autumn brings people close to nature and itˈs good for health. Both chrysanthemum and zhuyu are also clean plants and they can clean houses and make people healthy.In China, nine has the similar pronunciation with the word "forever", meaning long life. So the Chinese government set the day as the Seniorˈs Day in 1989—a day to respect the old. Many companies and communities organize autumn trips for old people. Young people bring elders to the countryside to enjoy nature. They also give them gifts.In China, it is a tradition to respect old people. In the past, if young people didnˈt take good care of their parents, they would be seriously punished. Now we have the 24 Filial Exemplars (《新二十四孝》). It includes 24 things we should do for elders, such as calling them up every week and going to see them more often. On this three-named festival, remember to show your love to your elders.17.Which is NOT a name for the festival?A. Chongyang Festival.B. the Double Ninth Festival.C. Seniorˈs Day.D. Youth Day.18.Which was not a tradition for this festival in the past?A. Climbing mountains.B. Calling them up every week.C. Drinking chrysanthemum wine.D. Wearing a plant called zhuyu.19.What does the underlined word "respect" in Paragraph 3 mean in Chinese?A. 思念B. 尊重C. 保护D. 照顾20.What is the main idea of the passage?A. History of Chongyang Festival.B. Introduction of Chongyang Festival.C. Traditions of Chongyang Festival.D. Symbols of Chongyang Festival.21.We can read the passage from a magazine called ______.A. American HistoryB. Chinese HistoryC. Western FestivalsD. Traditional Festivals三、阅读七选五（本大题共5小题，共12.5分）How to Be More Present Many people have a tendency to live in the past or the future. They constantly think about the past and worry about the future, and thus find it difficult to enjoy the good things in life in the here and now. You might unfortunately be one of these people. (22) Here are some tips that might help you.Notice Your SurroundingsOne way to be in the present moment is by noticing your surroundings. How often do you take time out of your day to actually look around and see what's going on? Now close your eyes and take a deep breath. (23) When you do, it's easier to be more present in the moment.Be Grateful for What You Have Now(24) If you are constantly focused on things you don't have, you aren't taking the time to appreciate what you have at this moment. One way to practice gratitude is to write a list of things you are grateful for and review that list on a daily basis. Try to write at least three things you are grateful for in your life right now.Show AcceptanceIf you want to learn how to be more present, you need to let go of how you think things should be and accept them for what they are. (25) Sometimes life is going to be different than how you want it to be. Practicing acceptance will help you let go of the things in your life that are out of your control.Find Positive Social SupportThe kind of social support you have in your life can also play an important role. Surrounding yourself with positive, supportive people will increase your own positivity and happiness levels. (26)A. Then open them and really take in where you are.B. You should focus your attention on one thing at a time.C. You cannot control everything that happens around you.D. This is one way to distance yourself from what you are enjoying.E. In turn, this will allow you to focus on what is going on right now.F. Part of living in the present moment is to appreciate what you have now.G. So learning how to live in the moment can greatly improve your well-being.四、完形填空（本大题共15小题，共15分）In the fall of 2008, I was looking to leave my current job in a doctor's office to explore something more (27) .

易错点01 地球与地图易错题【01】无法分清大圆和最短航线若两地的经度差不等于180度，则经过这两点大圆不是经线圈，而是与经线圈斜交，其最短航线不经过极点，具体分为两种情况：①甲地位于乙地的东方，从甲到乙最短航程为：同在北半球，先向西北，再向西，最后向西南；同在南半球，先向西南，再向西，最后向西北；位于不同半球时，需要讨论哪一段为劣弧段。

②甲地位于乙地的西方，从甲到乙最短航程为：同在北半球，先向东北，再向东，最后向东南；同在南半球，先向东南，再向东，最后向东北；位于不同半球时，需要讨论哪一段为劣弧段。

易错题【02】无法正确处理等高线和坡度的相互关系根据等高线疏密，判断坡度陡缓。

等高线稀疏的地方表示缓坡，密集的地方表示陡坡，间隔相等的地方表示均匀坡。

等高线的凸出部分指向低处表示山脊，其最大弯曲处的点的连线，表示为山脊线，也叫分水线。

等高线凸出部分指向高处，表示为山谷，其最大弯曲处点的连线，表示为山谷线，也叫集水线。

判断两点间可否通视，可通过绘制地形剖面图判断。

等高线上疏下密表示凸形坡，一般不可视；等高线上密下疏表示凹形坡，一般可视，在等高线图上判断河流流向时，要注意等高线的弯曲方向与河流流向相反。

易错题【03】不会描述地形特征根据等高线判定地貌特征可以从“以何种地形为主”“地势的高低起伏”“各种地形的分布（此条只大范围地区用）”等方面回答。

01无法分清大圆和最短航线西北通道是指从北大西洋经加拿大北极群岛进入北冰洋，再进入太平洋的航道。
