8、ut cultures C.They are related to nature D.They are intended for the young B When an animal species is considered endangered,it means that the International Union for Conservation of Nature(IUCN)has evaluatedit as nearly extinct,which means that a majority of its population has already died off and

9、the rate of birth is lower than the speciesdeath rate.Today,more and more animal and plant species are on the way to extinction because of a variety of major factors that cause a species to become endangered,and as you might expect,humans play a role in quite a few of them in fact,the biggest threat

10、 to endangered animals is human encroachment(侵入)on their habitats.Every species needs a habitat,where an animal finds food,raises its young.Unfortunately,humans destroy animal habitats in a number of different ways:building houses,clearing forests to getlumberand to plant crops,draining rivers to br

11、ing water to those crops,and making streets and parking lots.In addition,human development pollutes the environment with all kinds of chemicals,which destroys food sources and shelters for the creatures and plants of that area.As a result,some species die out while others are pushed into areas where

12、 they cant find food and shelters to make matters worse,when one animal population suffers,it affects many other species in its food web,so more than one speciespopulation is likely to decrease.Habitat destruction is the number one reason for animal endangerment,which is why conservation groups work

17、cted to double in the next 40 years.Clearly,the planet cannot stand such a high rate of forest loss.The second great problem with paper is what happens once it is no longer useful.A large amount of wastepaper ends up in landfills,where it can produce harmful gases and finally contribute to global cl

18、imate change.One simple solution can greatly reduce both of these problems:paper recycling.Instead of cutting down trees,recycle existing paper to feed the paper-making process.Paper is mainly made from cellulose(纤维素)，which can be used repeatedly in papermaking.Unfortunately,it also means that paper

19、 waste takes a surprisingly long time to break down in landfills.So far,trees are the only source(来源)of cellulose that can fill the great demand for paper products.Therefore,recycling paper is simply one of the best ways to save trees.Thanks to advances in processing,recycled paper need not be the d

21、ling,more effective recycling systems can be developed.The need is real.The massive loss of trees affects everybody on earth.Everyone should do their part to recycle paper and encourage government and industry to do the same.The world will be a better place for it!8.What can we infer from the text?A

24、ns and data.C.By discussing problems and solutions.D.By comparing strengths and weaknesses.D Imagine turning on the GPS and seeing an image of your car from above.As the car drives,the map follows along in real time,alarming you to any traffic,pedestrians,animals,or other things nearby.Routes and na

25、mes of roads appear over the live stream.Its like the map has come to life.This type of map isnt available yet.But it could be soon.In 2014,the Worldview-3 satellites was launched into space.Even though it orbits Earth at more than 370 miles（600 km）away,it can capture images of objects on Earth that

27、te and other US spy satellites have the technology to take even sharper images,with a resolution（分辨率）of up to around 4 inches（10cm）.ButUS law forbids making these super-sharp pictures public,to prevent enemies from using them.But the idea that anybody might be able to spy on the entire Earth in such

28、 detail may seem horrible.Live,high-detail satellite mapping could possibly be used to monitor anybody at any time.Ray Purdy of University College London told CNN that he is concerned about what this could mean for privacy.Most satellites are commercially owned,so if you have money you can buy that

29、imagery.“It means anyone can spy on anyone,”he said.At the same time,live,detailed maps of Earths surface could be useful in amazing ways.Live maps of a disaster area could quickly discover people in need of rescue as well as the safest routes in or out.Satellite images are already helping catch ill

30、egal logging and fishing operations.Higher detail may make it possible to catch other criminals in the act.The images could also make it easier for farmers to watch over their crops.What do you think?Do you wish everyone could access high-detail live maps of Earths surface?12.What does the underline

31、d word in paragraph 2 mean?A.Seeing B.Standing C.Walking D.Hearing 13.Why does US law forbid making super-sharp pictures public?A.to protect the technology.B.for the sake of safety.C.to protect the environment.D.to threat other countries.14.Which of the following statements is true according to the
