It is well known that Einstein was the father of the famous Theory of Relativity. But do you know it owes a great deal to Marits, Einstein’s former wife?In 1896, 17-year-old Einstein went to Zurich to study physics. There he met a girl from Hungary. They studied in the same class. The same interest brought the two together and the young man fell in love with Marits. In 1903, when Einstein was 24 years old, he married Marits, who was 4 years older than he.After their marriage, Einstein devoted himself to the research of the great theory. To give her husband more help, Marits gave up her own work, and became a good wife and assistant. She tried her best to encourage him whenever possible and she was sure that her husband would succeed. They often discussed the theory while walking outside or sitting together in the room. They even discussed it in their letters when one of them was away from home.In 1914, the Einstein moved to Berlin and settled there. At that time, Einstein’s theory proved to be correct and he had become famous all over the world. Marits was very proud of him and his success. But it was not long before the First World War broke out. Marits as well as her two sons, who were all on holidays in Switzerland, couldn’t come back to Berlin. The war not only stopped Einstein’s work but broke up the warm, happy family. In 1919, Einstein and Marits had to get divorced.Einstein himself, however, later said that Marits was really an outstanding woman.小题1:From the first paragraph, we can infer that the passage is mostly about __________.A．Einstein’s former wifeB．Marits’s love for EinsteinC．Einstein’s famous theoryD．the life of Einstein and his former wife小题2:Einstein fell in love with Marits mainly because they ________.A．were in the same schoolB．wanted to do research togetherC．had the same interestD．came from different countries小题3:By the year of 1914, Einstein had _________________.A．become famous all over the worldB．been proud of his successC．suffered from the 1st World WarD．lost touch with Marits小题4:Einstein and Marits got divorced because ________________.A．they no longer loved each otherB．the 1st World War broke outC．Marits went away with the childrenD．Einstein had become famous

The German government isn't just banning some children's smartwatches - it's telling people to "destroy" the gadgets (小玩意) already popular around the country． On Friday， Germany's telecom regulator the Federal Network Agency announced that a number of these devices， designed for ages 5to 12， can allow someone to remotely tap into the watch's microphone and spy from remote locations． The regulator isn't just concerned about the potential of people spying on children - it's concerned that the devices can be used to spy on anyone． And in Germany， it's illegal to record private conversations without permission． "According to our investigations， parents were using the watches， for example， to listen in on teachers during class．" said Federal Network Agency President Jochen Homann in a statement． Smartwatches that make phone calls， like the Apple Watch， are legal in Germany． The problem with many of the children's smartwatches， however， is that the devices have a classic snooping (监听) function， similar to a baby monitor， which can be easily activated just by using an app． "Via an app， parents can use such children's watches to listen unnoticed to the child's environment and as such， they are to be regarded as an unauthorized transmitting system，" said Homann． The German regulator is so serious about destroying these devices； it's asking citizens to record the watches' destruction and to file evidence online． Once the watches are destroyed， the regulator will provide a "certificate of destruction"， confirming the deed was done． This isn't the first time the Federal Network Agency told German citizens to destroy a consumer device． In February， the regulator prohibited the doll "My Friend Cayla" and treated it as an "spy device．" Apparently， the dolls were fitted with radio transmission technology that could allow children to be spied on． Beware consumer tech producers： The German government won't just ban devices that make spying possible； they'll demand the devices be destroyed with hammer (or whatever means of destruction one prefers) - even if they're dolls． 58． We can know from the passage that ． A． smartwatches can be used to spy on anyone except children B． it is legal for parents to listen in on teachers via smartwatches C． people needn't worry about the snooping function of smartwatches D． the destruction of smartwatches can be confirmed by a certificate 59． By mentioning the doll "My Friend Cayla"， the author aims to show ． A． the popularity of radio transmission technology B． the determination of the German government C． different forms of spy devices in Germany D． German citizens' trust in their government 60． Where can you probably find the passage？ A． In a news report． B． In a tourist brochure． C． In a research paper． D． In a technology magazine．

Coping with Climate Change What we have learned so far about climate changes is affecting our global environment. Studies show that it adversely affects human and natural systems by reducing biodiversity, impairing biological and chemical circles and making it more difficult to restore degraded ecosystems. Climate is not the only factor in the deterioration of natural systems. We are making big changes to the landscape, altering land use and land cover in major ways. These changes combined present a challenge to environmental management. Adaptive management is a scientific approach to managing the adverse impacts of climate and landscape change.Nature and Impacts of Climate Change Every week it seems there is an article about global warming in the news media. It may be difficult for some to grasp the big picture of the issue, but in general, climate change has already or is expected to ・ increase temperatures, particularly in the interior of continents, toward the poles and in winter; ・ boost precipitation(降水量) in wetter areas and suppress precipitation in drier areas; ・ increase rain and decrease snow; ・ lessen peak spring runoff and cause more even year-round flow of water, thereby reducing water availability during summer irrigation and navigation seasons; ・ increase evaporation of water during the summer; ・ enhance the likelihood of lower mean lake levels, drier wetlands, and water shortages, particularly in mountain regions; ・ raise the frequency and magnitude of extreme weather events, such as hurricanes, tornadoes, and floods; ・ raise global sea levels, causing some populated coastal areas to become inundated(被淹没的) ; ・ reduce the extent and duration of Arctic sea ice with adverse consequences for marine mammals; ・ increase the losses of glaciers in middle and equatorial latitudes, including premier mountain ecosystems such as Glacier National Park in Montana. Global average temperature had increased by about 0.6℃ over the past 100 years, with a major warming upswing in the 1970s. Warming is the result, in part, of rapid increases in emissions of greenhouse gases(GHG), particularly carbon dioxide(CO2), which is a byproduct of the combustion of fossil fuels, such as coal, oil, and natural gas, used for power generation and transportation. When global temperatures rise and precipitation patterns change, it is expected there will be consequences on ecosystems, such as an increase in the spread of exotic species, redistributing of plants, animals, energy, water and nutrients; alteration of natural processes and the structure and function of ecosystems. Northerly latitudes are particularly vulnerable to climate change. The Arctic Council, an intergovernmental forum for Arctic nations and indigenous people, reported that the northern ice cap is warming at twice the global rate and the Arctic region is expected to warm a two or three times the rate for rest of the world. Arctic warming will have serious consequences on human and ecology.Nature and Impacts of Landscape Change Landscape change results from natural disturbances and human activities. Natural disturbances include fire, windstorms, avalanches, landslides, tree fall, floods, and insect epidemics. Human activities causing landscape change include conversion of forestland to agriculture, drainage of wetlands, and forest fragmentation form road construction and timber harvesting. Human activities often have a more significant effect on landscapes than natural disturbances because they alter the availability of energy, water, and nutrients to ecosystems; increase the spread of exotic species; accelerate natural processes of ecosystem change; and adversely affect the structure and functioning of ecosystems. Human-induced landscape change has accelerated during the past several decades because of rapid population and economic growth, particularly in countries such as China, India, and Brazil. Landscape change had contributed to a dramatic 1.000-fold increase in species .extinctions over the past 400 years. On a global basis, nearly 1.2 million km2 of forest and woodland and 5.6 million km2 of grassland and pastureland have been converted to other uses. During the last three centuries, 12 million km2 of cropland were lost. Between 1982 and 1997, 121000 km2 of non-federal land were urbanized in the United States. More than 90 percent of the land in the lower 48 states has been logged, plowed, mined, grazed, paved, or otherwise modified from previous conditions. Human-induced landscape change significantly affects wildlife. For example, between 1970 and 2000, rural residential development in the Montana and Wyoming portions of the Greater Yellowstone Ecosystem increased 400 percent. Consequently, current and potential grizzly bear habitat on private lands in the ecosystem has been degraded and fragmented. Double-digit growth in residential subdivisions adjacent to the National Elk Refuge in Jackson, Wyoming, has diminished winter range for the 10000 elk that use the refuge and displaced corridors that elk use to reach summer range in Yellowstone and Grand Teton National Parks. Another example of significant impacts from landscape change is the Crown of the Continent Ecosystem. This ecosystem covers the Rocky Mountains in British Columbia and Alberta, Canada, and western Montana, United States. Here are some specifics: ・ Most old-growth forests that once existed outside of protected parks and wilderness areas have been harvested. ・ Many rivers in the region have been altered by hydroelectric power development. ・ Significant farm, ranch, and forest acreage has been converted to homes and commercial developments. ・ Lakes and streams have been polluted by agricultural and urban runoff. ・ Fish and wildlife habitats have been degraded. ・ Active and proposed energy developments threaten protected areas. ・ Large areas have been invaded by normative species. The desire to preserve the outstanding wildlife( especially large carnivores) and environmental amenities(舒适 ) from the negative effects of rapid economic growth and development in the northern Rocky Mountain region prompted creation of the Yellowstone to Yukon Conservation Initiative. The initiative involves 300 conservation organizations and covers an area larger than the states of California and Texas combined, including the Greater Yellowstone and Crown of the Continent Ecosystem.Coping with Climate and Landscape Change Although climate and landscape change has positive effects on human and natural system, it is expected to have many adverse impacts that deserve attention. Ecosystems have an inherent capacity to resist climate and landscape change, known as ecological resilience(复原能). When this capacity is exceeded, the ecosystem can change in ways that may not be socially and ecologically acceptable. So what can be done Mitigation strategies can reduce ecosystem vulnerability. Mitigation strategies are actions to prevent, reduce, or slow climate and/or landscape change. The Kyoto Protocol to the United Nations Framework Convention on Climate Change, which took effect in February 2005, is a prime example of a climate change mitigation strategy. The protocol commits 36 industrialized countries to curb GHG emissions, especially CO2. Limiting increases in global temperature by 2℃ would require keeping atmospheric concentrations of CO2 below 400 parts per million(ppm). Current concentrations are about 375 ppm. Benefits from the Kyoto Protocol may be limited because it does not include some developed countries, which emit substantial GHGs, and developing countries where rapid population and economic growth is expected to dramatically increase GHG emissions. Other mitigation: strategies include increasing the use of alternative energy sources and technologies (clean coal, renewable energy, ethanol, hybrid vehicles, and nuclear power). Although the United States did not sign the Kyoto Protocol, 28 states have programs to curb CO2 emissions, and at least 166 U. S. cities have agreed to apply the Kyoto emission reduction standards to their communities. Other initiatives, like the Apollo Alliance, bring together labor unions, environmental and business groups, and activist: organizations with the mission of sharply reducing U. S. dependence on fossil fuels. The alliance is seeking ways to do the following: ・ power the economy with hydrogen produced from renewable energy resources; ・ implement green construction codes; ・ revitalize urban centers to reduce urban sprawl; ・ determine how industry can store rather than emit carbon into the atmosphere. The Apollo Alliance expects to invest 300 billion in new energy technologies and energy conservation over 10 years as a way to eliminate U. S. dependence on foreign oil and create millions of good-paying jobs. There funds would be raised using tax incentives, public bonds, capital strategies, and other mechanisms.Which of the following is NOT the result of landscape change in the Crown of the Continent Ecosystem A. Old forests once existed in the protected park have been cut down.B. Hydroelectric powers affect the river.C. A mass of land has been converted to residential and commercial regions.D. Lakes and rivers have been polluted by rural and urban runoff.
