They can 1 earn your preferences and schedules, and then adjust the temperature according!y. They* re better-looking and more enjoyable to use than the basic pieces of plastic that occupy most households. Their very presence wi11 probab1y make you more conscious about saving energy. And once you, re able to heat up or cool down your house from your phone, wi thout having to get out of bed, you won , t want to go back.If you live in a larger household, the ecobee3 can be much more convenient-provided you pick up a couple more remote sensors. Yes, it gets pretty expensive at that point, but having those gives you effective control over the temperature in different rooms around your house. In comparison, other thermostatsJ measurements are largely limited to the area in which they* re installed （安装）.If you live in a smaller place, that, s no big deal; the ecobee3 still has distinct advantages. It is touch-enabled and more spacious, making it less annoying when you want to enter a WiFi password, see weather information, and so on. Still, all the smart thermostats are pretty great. Which one is best just depends on whether you need a whole-home solution or a more straightforward one. For now, if it* s the former, go with the ecobee3.Ecobee3 Smarter WiFi Thermostat with Remote Sensor, available at al 1 shopping websites.21.

They have to show that they will be able to pay for each year of study. Students have to consider not only the tuition, the cost of classes, but also meals and a place to live in, which is known as room-and-board. They also need money for books and supplies. And they need money to spend on social activities and other things.Educational advisers say foreign students should have enough money in a local bank to pay for at least two months of expenditure. So how much will a year at an American school cost? Generally speaking, the answer is: a lot. A leading state university in the Pacific Northwest will serve as an example. The University of Washington says foreign students are paying more than $36, 000 this year. This major research university currently has 2,600 foreign students from more than one hundred countries. There are many schools that cost less, but also others that cost more. Its web site says the University of Washington doesnot offer financial assistance to international students. This is generally true of American schools, especially at the undergraduate level.The international application for the university includes a Statement of Financial Responsibi 1 ity that must be signed. Students must also provide a bank letter or statement from within the past six months. And they have to name someone who wi 11 help wi th payments. These people must send proof from a bank to show that they have the money. Your government or employer may be able to help you pay all or some of the college costs. A good idea is to ask at least eighteen months before you want to start classes in the United States.Our Foreign Student Services, including links to web sites discussed in our reports, can be found at . To learn more about higher education in America, the StateDepartment has a special web site: educationusa. state, gov.24.Students who are going to study in America mustA.buy their own textbooks themselvesB. prove that they can pay for their studyC. find a living place with a kitchenF). find someone to pay for their college fees25. Who is thisspeech probably givento?A.Studentswhoare going to graduatefrom col leges.B.Studentswhoare going to college in the US.C.Studentswhoare going to apply for room-and-board.D.Studentswhocan* t pay for their college study by themselves.26. What isNOTa must if you, a foreign student, apply for the university in the US?A. Apply eighleen months before you want to start.B. A signed Statement of Financial Responsibility.C. People who will help you pay for the study should provide a bank proof.D. A bank letter from within the past six months.27. What is the speaker* s purpose in this speech?A. To tell foreign students that money is the most important thing in the US.B.To advise foreign students to apply as soon as possible so as to have more chances.C. To state some requirements that foreign students should pay attention to when applying for colleges.D. To tel 1 people about the present situation of foreign students in the US.Imagine, one day, getting out of bed in Beijing and being at your office in Shanghai in only a couple of hours, and thereafter a full day of work, going back home to Beijing and having dinner there.Sounds unusual, doesn' t it? But it' s not that unrealistic, with the development of China's highspeed raiIway system. And that , s not al 1. China has an even greater high-speed railway planto connect the country with Southeast Asia, and eventuallyEastern Europe.China is negotiating to extend its own high-speed railway network to up to 17 countries in 10 to 15 years, eventually reaching London and Singapore. China has proposed three such projects. The first would possibly connect Kunming with Singapore via Vietnam and Malaysia. Another could start in Urumqi and go through Kazakhstan and Uzbekistan, and possibly to Germany. The third would start in the northeast and go north through Russia and then into Western Europe.If China* s plan for the high-speed railway goes forward, people could zip over from London to Beijing in under two days. The new system would still follow China's high-speed railway standard. And the trains would be able to go 346 kilometers an hour, almost as fast as some airplanes. China's bul let train（高速客车），the one connecting Wuhan to Guangzhou, al ready has the world's fastest average speed. It covers 1,069 kilometers in about three hours. Of course, there are some technical chailenges to overcome. There are so many issues that need to be settled, such as safety, rail gauge （轨距），maintenance of raiIway tracks. So, it's important to pay attention to every detail.But the key issue is really money. China is already spending hundreds of billions yuan on domestic railway expansion. China prefers that the other countries pay in natural resources rather than with capital investment. Resources from those countries could stream into China to sustain development. It' 11 be a win-win project. For other countries,the railway network will definitely create more opportunities for business, tourism and so on, not to mention the better communication among those countries.For China, such a project would not only connect it with the rest of Asia and bring some much-needed resources, but would also help develop China' s far west. We foresee that in the coming decades, millions of people will migrate to the western regions, where the land is empty and resources unused. With high-speed trains, people will set up factories and business centers in the west once and for all. And they*11 trade with Central Asian and Eastern European countries.28. China ' s new high-speed raiIway plan wi11 be a win-win project because.A. China will get much-needed resources and develop its western regionsB. China and the countries involved will benefit from the project in various waysC. China will develop its railway system and communication with other countriesD. the foreign countries involved will develop their railway transportation, business and tourism29. According to the passage, the greatest challenge to the new high-speed railway plan is.A. technical issuesB. safety of the system1. financial problemsD. maintenance of railwaytracks30. Which of the fol lowing words best describes the author,s attitude towards China* s high-speed raiIway plan?A. Critical.B. Reserved.C. Doubtful.D. Positive.31. Which of the following might be the best title for the passage?A. New Railway StandardsB. Big RaiIway DreamsC. High-speed Bullet TrainsD. International RaiIway NetworkDThe largest genetic study of mosquitoes has found their ability to resist insecticides（杀虫剂）is evolving rapidly and spreading across Africa, putting millions of people at higher risk of contracting malaria（疟疾）.British scientists who led the work said mosquitoes, growing resistance to control tools such as insecticide-treated bed nets and insecticide spraying, which have helped cut malaria cases since 2000, now threatens “to disturb malaria control" in Africa.“Our study highlights the severe challenges facing public efforts to control mosquitoes and tomanage and limit insecticide resistance, n said Martin Donnelly of the Liverpool School of Tropical Medicine, who worked on the study with a team from Britain, s WeiIcome Trust Sanger Institute.Latest World Heal th Organization （WHO） data show that 216 million people were infected last year with the malaria parasite（寄生虫），which is transmitted by blood-sucking Anopheles mosquitoes. The disease killed 445, 000 people in 2016, and the majority of them were children in sub-Saharan Africa.To understand how mosquitoes arc evolving, the researchers scqucnccd the DNA of 765 wild Anopheles mosquitoes taken from 15 locations across eight African countries. Their work, published in the journal Nature on Wednesday, created the largest data resource on natural genetic variation for any species of insect.Analyzing the data, the scientists found that the Anopheles gamblae mosquitoes（冈 比亚疟蚊）were extremely genetically diverse compared with most other animal species. This high genetic diversity enables rapid evolution, they said, and helps to explain how mosquitoes develop insecticide resistance so quickly.The data also showed the rapid evolution of insecticide resistance appeared to be due to many previously unknown genetic variants（变体）within certain genes. The scientists said these genetic variants for insecticide resistance were not only emerging independently in different parts of Africa, but were also being spread across the continent by mosquito migration.Michael Chew, an expert at Britain' s Wellcome Trust global health charity which helped fund the research, said the finds underlined the importance of pushing scientific research ahead to control malaria.Global efforts to control malaria through effective vaccine, insecticides and the best drug combinations require urgent, united action by scientists, drug companies, governments and the WHO.32. Which of the fol lowing is scientists* headache?A. The number of mosquitoes in Africa is growing rapidly.B Some genetic variants of mosquitoes are still unknown.C. The existing insecticides aren' t as effective as they used to be.1） . Millions of African people have resistance to medicines for malaria.33. Malaria cases can be cut by .A. threatening drug companiesB. spraying insecticidesC. limiting blood donationD. transmitting data34. What CANNOT be concluded from the passage?A. Children are more likely to be bit by mosquitoes.B. Many previously unknown variants are found in the study.C. The mosquito migration conlribules lo Ihe spread of variants.D. Anopheles mosquitoes have great genetic diversity.35. Which is FALSE about the genetic study of mosquitoes?A. It created the largest data on natural genetic variation for any insect species.B. It found the possible causes for the rapid evolution of insecticide resistance.C. It discovered where the genetic variants emerged and how they were spread.D. It highlighted the public efforts and appealed to limit the use of insecticides.E七选五阅读。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。选项中有两项 为多余选项。Choosing a major is a very important thing in our life.
