But while for me they represent treasured memories, to others they are more often than not simply a collection of boring, badly composed, out-of-focus pictures. So this year I decided to do something about this by booking myself on a trip to Rome which included photography lessons.The first time I went to Rome, I remember thinking that it was a fantastic place for photographers with a wonderful photo opportunity lying around every corner. Yet by myself I didn't have a clue how to go about getting some good shots. Added to this was the fact that there were crowds of tourists everywhere, blocking all the best views. But this second time things were different. Antonio, my photography tutor, was on hand to give expert advice every step of the way. The first thing Antonio told our group was that the secret to creating a good photographic image rather than just a snapshot(快照)is to first take a long look at what you want to photograph. Our first port of call was Piazza Navona, where Antonio gave us advice about how to photograph the Fountain of Neptune. For the next couple of hours, we wandered around the historic center visiting many of Rome's architectural highlights. I didn't get at all tired, even though I was on my feet for such a long time. And I felt that I was really able to appreciate the sights as I had to look at each one so carefully in order to get good pictures. It felt like a whole new world had opened up to me.I learnt an incredible amount over the next two days, as well as having a thoroughly enjoyable time in one of the world's most beautiful cities. Maybe my friends and family will show a little more enthusiasm when I show them my holiday snaps from now on!4、What motivated the author to book a photography trip to Rome?A. Her interest in trying out a new hobby.B.Her desire to explore the city of Rome.C.Her dissatisfaction with her photography skills.D. Her hope of finding inspiration for her photography.5、Which words can best describe the author's first experience in Rome?A.Confusing and disappointing.fortable and uneventful.C. Fantastic and adventurous.D.Relaxing and interesting.6、What did Antonio suggest concerning photography in Rome?A.Taking multiple snapshots of each subject.B.Observing the subject before taking a photo.C. Avoiding crowded areas for better pictures.D.Looking at surroundings to unlock their secrets.7、How did the author benefit from her photography tour of Rome?A.She began to see things in a new light.B.She understood her friends and family better.C. She was able to appreciate beautiful photos.D. She became more enthusiastic about snapshots.Small sensors powered only by sunlight could float (漂浮) in the sky forever and make weather-related measurements.Flat objects with two sides can be kept up in the air by what is called photophoresis (光泳现象).This occurs when one of the sides absorbs lots of light and the other very little, creating a difference in temperature. Just like how temperature differences in the atmosphere cause winds, this difference makes molecules(分子) move in such a way as to create a lifting force on the object.Benjamin Schafer at Harvard University and his coworkers designed a device that could use photophoresis to lift small weather sensors into the air and wouldn't need motors or batteries to keep up the height.Their device consists of two discs. Each disc is only 100 nanometers thick --- one-thousandth the thickness of a sheet of paper --- and very small holes cover nearly half of the surface, making it very lightweight and easy for heat to flow through it. To maximize the lifting forces on the device, the team decided to cover the top disc with a coating that lets visible but not infrared light (红外线) pass through it, while a coating on the bottom disc did the opposite. This would produce enough lift to keep the device in the stratosphere(平流层) and it would never fall to Earth. The researchers calculated that the device could carry a 300-milligram load of equipment, such as temperature and pressure sensors.Schafer and his coworkers suggest a weather balloon could deliver hundreds of these devices to the stratosphere where they could measure stratospheric winds, which are usefulto Mars, where they could collect data abour the Martian atmosphere.Karen Aplin at the University of Bristol, UK, says that the device might be helpful for solar geoengineering."However, the device's 300-milligram mass allowance (限额) may challenge its practicality. Many instruments would have to be powered by solar cells and adding those, together with other elements, could limit how many more instruments can be added,"she says.8、What makes photophoresis happen?A.Wind force.B.Molecule difference.C. Object shapes.D.Temperature difference.9、How did the designers give the device the strongest lifting force?A.By making holes all over it.B.By coating its discs in the opposite way.C.By increasing its surface area.D.By sending it to the stratosphere.10、What does the underlined word "viable" in paragraph 5 mean?A.Practical.B.Distant.C.Legal.D.Accurate.11、What does Karen Aplin imply about the device?A. Its high costs challenge its practicality.B. It is better than battery-powered sensors.C. It can hardly resist extreme temperatures.D. Its mass allowance may limit its application.As an ecologist and consultant, I have been involved with a range of ecosystem restoration(修复) projects. It is clear to me, as it will no doubt be clear to readers, that ecosystem restoration is crucial. As we seek to ease and adapt to climate change, and work to reverse (逆转) biodiversity losses, restoration is an important part of the global solution. But while it is widely understood that ecosystem restoration is the right thing to do, there is far less understanding about what exactly it means, and how it is to be achieved.One of the most obvious misunderstandings about ecosystem restoration is that it is all about action, especially planting trees. It is important to understand that forest and woodland ecosystems are not the only crucial environments to restore. Ecosystem restoration consists of a huge range of different systems from farmland soils and grassland systems to our seas andoceans.Ecosystem restoration is not always about actively intervene (干预). In many instances, passive intervention can be just as effective, if not more so, than active. This involves simply letting nature take the reins(掌管). But there are situations in which humans have damaged the environment to such a degree that natural restoration is impossible. This is when carefully designed action is required.Another key thing to remember is that we cannot succeed in ecosystem restoration without local people's involvement or, ideally, their leadership. When a community feels a sense of belonging and a deep connection with the land, this provides a firm foundation for future conservation and restoration work.While I dislike taking an overly human-centered view, environmental issues cannot be separated in our complex modern world from socio-economic ones. We need to look at people and the planet as a whole and appreciate the complex web of human life and its interaction with the natural world in order to form practical restoration solutions. It is only when we consider the natural environment and human society as interconnected that we can really continue to make progress.12、Which shows the proper understanding of ecosystem restoration?A. Community-led efforts should be reduced.B. Ecosystem restoration involves a variety of systems.C. Direct action on forest ecosystems should be avoided.D.The more trees we plant, the better the ecosystems will be.13、In what case is active intervention a must?A.Nature fails to restore itself to health.B.The cost of passive intervention is high.C. A large population relies on natural resources.D. Active intervention can improve the local economy.14、According to the last paragraph, what should be done to make practical restoration plans?A. Focusing on the interests of humans.B. Making nature conservation a top priority.C. Conducting a survey of local natural resources.D. Taking both social factors and nature into account.15、What is mainly talked about in the text?A.How people can benefit from ecosystem restoration.B.What challenge people face in ecosystem restoration.C.Why ecosystem restoration becomes increasingly urgent.D. How we can repair damaged ecosystems more effectively.二、七选五16、How to Handle an Argument with Your Family MembersWe've all been there. A relaxed evening with our family members. A lot of laughing. And then, as if someone had sat on the TV remote and changed the channel, the mood shifts. No more warmth. Suddenly there's shouting, a ping-pong of accusations(指责), deadly stares, and hostility(敌意) streaming from eyes like red laser pointers. Having a conflict with your family members is frustrating, and you may feel sad and depressed. ①________ Do remember that as much as it might feel this way, you're not in a court of law with your family members. ②________ .It is to restore kindness and connection. Think of it this way —if somebody wins, both parties lose.Do try to be an advocate of others'feelings. ③________ try to stand in the shoes of your family members. Try to understand their immature ways.④________ ,This might frighten your family members, making them feel accused and in turn, act defensively. Example:"I was on the phone with my sister and then suddenly you started acting like crazy out of the blue."Talk about the way you felt instead. Example:"I was on the phone with my sister and then I suddenly felt scared when I saw you looking at me like I was in trouble."Don't try to explain yourself. You often want to explain yourself when having conflicts with your family members, but you don't have time. You're being cut off and attacked again. ⑤________.The more you talk, the less your family members seem to understand and the further away you get from an agreement.A. If you are looking for a new relationshipB. Don't attempt to prove yourself in the face of your loved onesC. The point of an argument isn't to prove the others guilty or to winD. Rather than going in circles about what you think and how you feelE. Each accusation strikes deeper and deeper into your sense of justiceF. Don't talk about what happened as though you're simply stating the factsG.

Patience is a word that has appeared in many forms over the past two months.I don't see myself as being the most patient person in the world but there was something that struck me on my first week of work. I had just finished a session with two students and just as they were leaving the classroom, one of the students turned back and said, "Thank you for your patience." That was an early reminder of the importance of being patient as a teacher. It also made me reflect on the language teachers that I have had over the years, ones that demonstrated a high level of patience and understanding that has shaped my language learning path. Moreover, it helped me to realize the importance of demonstrating patience in the classroom as it can be the difference between building someone's confidence in a language or breaking down their confidence entirely.Living my life constantly in French is not easy but the people of Quebec are very patient. They repeat things several times and they are more than happy to wait while I find the correct words to express myself and find the correct word order. It's a learning process but with the patience of others, the process is slightly less nervous. At the end of the day, making mistakes shows you are trying and I think that is greatly appreciated by Quebecers.When I first arrived in Matane I kept getting headaches from having to concentrate all the time due to the language and even overhearing other people's conversations was hard work! I had to keep reminding myself that it would take time, and two months later the headaches are a distant memory and my ears have become more tuned to their accent. The key is to be patient with yourself.4.What is important as a teacher according to Paragraph 2?A.Understanding.B.Patience.C.Confidence.D.Help.5.In a small town called Matane, which language do the local people speak?A.English.B.Spanish.C.French.D.Italian.6.What about the author when hearing the student's words?A.She felt kind of surprised.B.She thought he was wrong.C.She realized she needed more patience.D.She was at a loss what to do.7.What can we infer according to the last paragraph?A.The key to success is patient with yourself.B.Don't be always talking with others ina new place.C.It takes two months to master a new language.D.The headache left the author a poormemory.CGenerating electricity from thin air may sound like science fiction, but a new technology basedon nanowire(纳米线) bacteria does just that —as long as there's moisture(水分) in the air. A new study shows that when fashioned into a film, these wires —protein lines that send electrons(电子) away from the bacteria —can produce enough power to light a light-emitting diode(二极管). The film works by simply absorbing humidity from the surrounding air. Though researchers aren't sure exactly how these wires work, the tiny power plants make a great difference: Seventeen devices linked together can generate 10 volts, which is enough electricity to power a cellphone.The new method should be considered a "milestone advance" says Guo Wanlin, a materials scientist at Nanjing University who wasn't involved with the work. Guo studies hydrovoltaics, a molecular approach to harvesting electricity from water.The way hydrovoltaic devices work is still a bit of a mystery. When water droplets interact with certain kinds of graphene (石墨烯) or other materials, an electric charge is generated, and electrons move through the materials. Many questions remain about exactly how these devices generate electricity, however. "I think a deeper understanding… is needed," says Dirk de Beer, a microbiologist developing microsensors at the Max Planck Institute for Marine Microbiology.Researchers are also just starting to learn how electron-conducting bacteria function. More than 15 years ago, co-author Derek Lovley, a microbiologist at the University of Massachusetts(UMASS), Amherst, and his colleagues discovered that a bacterium called Geobacter shuttles electrons from organic material to metal-based mixtures, such as iron oxides. Since then, he and others have learned that many other bacteria make protein nanowires to transfer electrons to other bacteria or deposits in their environments. This transfer creates a small electrical current, which researchers have tried with varying degrees of success as clean energy. Using water vapor is "a revolutionary technology to get renewable, green, and cheap energy directly from atmospheric wetness," says Qu Liangti, a materials scientist at Tsinghua University.8.What do "the tiny power plants" in Paragraph 1 refer to?A. Electrons.B. Protein nanowires.C. Seventeen devices.D. Light-emitting diodes.9.What is the purpose of the second and third paragraphs?A. To explain what hydrovoltaics is.B.To introduce Dirk de Beer’sdoubts.C. To stress the new method's advance.D. To tell how electron-conductingbacteria function.10.W hat can we learn from the text?A. Guo Wanlin is a co-author of Derek Lovley.B. Researchers are sure how protein nanowires work.C. Graphene mixed with iron oxides can make electricity.D. Researchers sometimes fail to get electricity from bacteria.11.W hich of the following is the best title for the text?A. Water Vapor is a Green and Cheap Energy.B.Molecular Harve Electricity fromWater.C. Electric Bacteria Create Currents out of Air.D. Hydrovoltaic and Nanowire DevicesRequire Power.DA completely new type of cooling panel has been created by researchers at Stanford University. The new structure works to reflect significant amounts of sunlight back into space even in full sunlight.To explain the breakthrough in specific terms: "a typical one-story, single-family house with just 10 percent of its roof covered by radioactive cooling panels could make up for 35 percent its entire air conditioning needs during the hottest hours of the summer."As the press release from Stanford University's Engineering site states it, "Tapping the cold sky of outer space to cool the planet. Science fiction, you say? Well, maybe not any more.""People usually see space as a source of heat from the sun, but away from the sun outer space is really a cold, cold place," says Shanhui Fan, professor of electrical engineering and the paper's senior author. "We've developed a new type of structure that reflects the vast majority of sunlight, while at the same time it sends heat into that coldness, which cools human-made structures even in the day time."The engineering "trick" that makes this possible is the crossing of an important thresh-hold. The reflector needs to be effective enough that it absorbs only a very low minimum of sunlight, and avoids heating up at all as a result. The other important factor is that the structure needs to be very efficient at reflecting heat back into outer space. "Thus, the structure must send out heat radiation very efficiently within a specific wavelength range in which the atmosphere is nearly transparent (透明的). Outside this range, Earth's atmosphere simply reflects the light back down." You're probably already familiar with this effect, it's commonly known as the greenhouse effect.The new cooling panel, made from nano-structured quartz and silicon carbide (碳化硅), fulfills both of these requirements. It's very effective at reflecting most sunlight, while also very effectively sending heat radiation in the wavelength range necessary to escape the Earth's atmosphere.12.W hat can the new solar structure be used to do?A.To turn light energy into electric energyB.To reflect amounts of sunlightbackC.To provide information for researchersD.To extend the hours of sunlightin winter13.A ccording to Shanhui Fan we can know that ____________.A.the earth will be cooled by outer spaceB.human beings are fightingagainst natureC.no one is capable of living in outer spaceD.such structures will be sent tospace14.W hat is the function of the reflector?A.To support and fix a thresh-hold.B.To take in sunlight effectively.C.To play a trick in the process.D.To keep the wavelength in order.15.W hat can we conclude from the passage?A.The solar structure can lower our bills.B.A majority of sunlight can berefused.C.The Earth's atmosphere will disappear.D.Humans can rule out greenhouseeffect.第二节（共5小题；每小题2.5分，满分12.5分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
