单元综合检测(二)unit 2the environment(时间：100分钟；满分：120分).阅读理解(共15小题；每小题2.5分，满分37.5分)aresearchers at stanford university have developed a new material that can move heat out of buildings and into space.the researchers say the material can cool buildings even on hot days.the cooling material is a very thin sheet with many layers that could be placed on a roof like solar panels(板)however, instead of turning sunlight into energy as solar panels do, the material turns heat into infrared(红外线的)radiation.shanhui fan is an electrical engineering professor at stanford university.he says that the panels have a layer of material that is like sand.the panels act like a mirror.they take heat out of buildings and reflect the light from the sun.and he says both the heat and sunlight are sent 100 kilometers into outer space.its a structure that cools itself without electricity input, even under the sun.so, what it does is basically radiate heat to outer space and also reflect the sunlight so it doesnt get heated up by the sun.mr.fan says it is like having a window into space.the heat is sent directly into space without increasing the air temperature.he says buildings in developing countries that do not have electricity or air conditioning could use the panels.“in areas where electricity is out of reach for many people, there is a potential benefit for storing medicine or even food.in many of these situations, being able to reduce the temperature is important.and this would provide a way to do it.”the researchers say the main problem is creating actual cooling systems using the hightech panels.they say it may be possible to develop a cooling spray(喷涂)that could be used on present solid structures.they believe the cooling spray technology could be developed in the next three to five years.they say as much as 15 percent of the energy used in the united states is spent providing power to air conditioning systems.【语篇解读】本文介绍一种被用来使建筑物降温的新材料。这种新panel既环保又节能，它仍在研究中。1what is

african elephant is to a great extent the builder of its environment.as a big planteater, it largely shapes the forestandsavanna(大草原) surroundings in which it lives, therefore setting the terms of existence for millions of other animals that live in its habitat(栖息地)it is the elephants great desire for food that makes it a disturber of the environment and an important builder of its habitat.in its continuous search for the 300 pounds of plants it must have every day, it kills small trees and underbushes, and pulls branches off big trees.this results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the african savannas.in these open spaces are numerous plants in various stages of growth that attract a variety of other planteaters.take the rain forests for example.in their natural state, the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor.by pulling down trees and eating plants, elephants make open spaces, allowing new plants to grow on the forest floor.in such situations, the forests become suitable for large hoofed planteaters to move around and for small planteaters to get their food as well.what worries scientists now is that the african elephant has become an endangered species.if the elephant disappears, scientists say, many other animals will also disappear from vast areas of forest and savanna, greatly changing and worsening the whole ecosystem.【语篇解读】文章主要讲述了非洲大象对生态的影响，并解释了具体原因。8what is the passage mainly about?adisappearance of african elephants.bforests and

chief.globally，pollution was linked to one death in eight in 2018，new who research found.the biggest pollution related killers were heart disease，stroke，pulmonary(肺的)disease and lung cancer.the hardesthit regions of the globe were what the who labels southeast asia，which includes india and indonesia，and the western pacific，ranging from china and south korea to japan and the philippines.together，they accounted for 5.9 million deaths.the global death toll included 4.3 million deaths due to indoor air pollution，chiefly caused by cooking over coal and wood stoves and so on.the toll from outdoor pollution was 3.7 million，with sources ranging from coal heating fires to gas engines.many people are exposed to both indoor and outdoor pollution，the who said，and due to that overlap(重叠)the separate death toll attributed to the two sources cannot simply be added together，therefore the figure of seven million deaths.the new figure is shocking，neira told reporters.when it last released an estimate for deaths related to air pollution，in 2008，the agency had put the figure related to outdoor pollution at 1.3 million，while the number blamed on indoor pollution was 1.9 million.but a change in research methods makes comparison difficult between the 2014 estimate and the 2018 figures，neira said.in the past，for example，the who did not take into account the overlap between exposure to both forms，and only assessed urban pollution.satellite imagery has made it easier to assess rural pollution，and new knowledge about the health impact of exposure has enabled a better count.【语篇解读】本文是说明文。文章主要分析了全球空气污染的原因及其造成的后果。12we can infer from paragraph 1 that aair pollution only comes from cooking fires and vehicle smokebair pollution has caused a big disaster to the
