leading-edge technology.Low-cost,dependable and small modern cameras are a big help.Cameras placed in hard-to-reach places have taken videos of everything from small desert cats to larger snowloving felines（猫科）in the northern Rocky Mountains.These cameras are important tools to learn new information on wildlife.Some videos help scientists see the effects of climate change.For example,the desert animal javelina and the treeloving coatimundi（长鼻浣熊）have been caught on cameras north of their normal home.This could mean global warming is enlarging their living area northward.Researchers use cameras along with global positioning systems,or GPS.They attach GPS devices（设备）to mule deer and antelope （羚羊）in and around Yellowstone National Park.Then they can record their movements,or migrations（迁移）.These cameras can be left in very rural（荒里予的）areas for days,weeks or even months.They can provide information on how many animals are moving over a given period of time.Rural video can show details about animal behavior,such as the calls made by migrating mule deer.Also,some cameras record animal life,showing everything from bison in Saskatchewan,Canada,to the underwater weed forest off California ' s Channel Islands.However,rural cameras have their problems too.Animals such as wolverines and bears sometimes attack them.Scientists do not know if the attacks are the results of anger or interest.Also,the devices have become popular tools to help hunters look for animals.Some people argue that it is unfair to use the cameras that way.Even with such problems,rural cameras are clearly an important scientific tool in researching wild animals.1.Which of the following helps scientists know about climate change?A.How active animals are.B.Where animals go.C.What animals eat.D.When animals move.答案:B解析:细节理解题。

高中英语学习材料madeofjingetiejiUnit 4 Wildlife ProtectionⅠ.阅读理解A体裁：说明文话题：动物词数：296 时间：6′Lions are family animals and truly social in their own communities.They usually live in groups of 15 or more animals called prides.Prides can be as small as 3 or as big as 40 animals.In a pride，lions hunt food，raise little lions，and defend their territory(领地) together.In prides the females do most of the hunting and care for little ually all the females in the pride are related—mothers，daughters，grandmothers，and sisters.Each pride generally will have no more than two adult males.While the females usually live with the pride for life，the males often stay for only two to four years.After that they go off on their own or are evicted(逐出) by other males who take over the pride.When a new male becomes part of the pride it is not unusual for him to kill all the little lions，making sure that all future little lions will have his genes.The main job of males in the pride is defending the pride's territory.A male's loud roar(吼叫)，usually heard after sunset，can carry for as far as eight kilometers.The roar warns off intruders(入侵者) and helps round up small members of the pride.Hunting generally is done in the dark by the females.They often hunt in groups of two or three，using teamwork to surround，and kill other animals.Females aren't the most successful of hunters，because they usually score only one kill out of several tries.After the kill the males usually eat first，females next and the little lions get what's left.Males and females defend against any outside lions that attemptto join their pride.【语篇解读】狮子是百兽之王。

To get to the other side.Most people know this joke.But recently, some people have been much more worried about how the grizzly bear and the mountain lion can cross the road.“Millions of animals die each year on the US roads，” the Federal Highway Administration reports.In fact, only about 80 ocelots, an endangered wild cat, exist in the US today.The main reason? Roadkill.“Eco­passages” may help animals cross the road without being hit by cars.They are paths both over and under roads.“These eco­passages can be extremely useful, so that wildlife can avoid road accidents，” said Jodi Hilty of the Wildlife Protectio n Society.But do animals actually use the eco-passages? The answer is yes.Paul Beier of Northern Arizona University found foot marks left by mountain lions on an eco-passage that went under a highway.This showed that the lions used the passage.Builders of eco-passages try to make them look like a natural part of an area by planting trees on and around them.Animals seem to__be__catching__on．Animals as different as salamanders and grizzly bears are using the bridges and underpasses.Next time you visit a park or drive through an area with a lot of wildlife, look around.You might see an animal on an overpass!1．The writer uses the example of ocelots to show that ________．A．wild animals have become more dangerousB．the driving conditions have improved greatlyC．the measure for protecting wildlife fails to workD．an increasing number of animals are killed in road accidents2．When the writer says that animals seem “to be catching on”，he means ________．A．animals begin to realize the danger on the roadB．animals begin to learn to use eco-passagesC．animals are crossing the road in groupsD．animals are increasing in number3．This passage is written to ________．A．protect the endangered animalsB．call on drivers to be careful when seeing animals on the roadC．introduce a new way to help protect wild animalsD．tell us the main reason for the killing of animals in the USBFood webs throughout the ocean are in trouble because of overfishing.About one billion people rely on seafood for protein.However, people are fishing more species faster than those fish can reproduce(繁殖)．By 2048, says the World Wildlife Fund, the number of all present food fish could reduce by 90%.So few fish would remain in the world that people couldn't depend on them for food.Climate changes will most likely trouble food webs further.As average global temperatures rise, the ocean gets more carbon dioxide.That makes the ocean more acidic, which does harm to the lives in the ocean.Fewer of those lives will grow stronger, leaving less to eat.There will be more effects on the food web.Aquaculture—raising fish and seafood in farms—isn't necessarily the answer to these problems. Sometimes companies destroy mangrove(红树林) forests and other sensitive habitats in order to build fish farms. Habitat destruction also leaves coastal areas easily flooded.“A lot of our freshwater comes from the ocean as rain，” says Shannon, an ocean scientist. Rain helps crops grow and provides drinking water.But it__can__have__a__dark__side，as when hurricanes cause flooding and blackouts even in inland states, such as Ohio, Missouri, and New Mexico.The ocean affects the air, too.“Half the oxygen that we breathe comes from photosynthesis(光合作用) of sea plants in the ocean，” adds Shannon.That sea air reaches from coast to coast.All those reasons suggest that we have to protect the ocean before it is too late.4．By saying “it can have a dark side”，Shannon means ________．A．rain can make drinking water darkB．rain can have a bad effect tooC．rain can get crops grow darkD．rain can become dark itself5．Which of the following is RIGHT according to the passage?A．By 2048, about one billion people will not depend on seafood any longer.B．Climate changes will most likely cause a lot of trouble to food webs.C．Aquaculture is necessary to solve these problems.D．The ocean and the seafood affect our surroundings.6．The purpose of this passage is to ________．A．prove the advantages of seafoodB．introduce the serious sea pollutionC．explain the formation of food websD．call on people to protect the oceanCWhen I first entered high school, I knew no one at my school.All my friends in middle school went to other schools.I wanted to make some new friends.However, I was shy and wasn't good at making new friends.On my first day at school, I looked at others who were talking in groups happily.How I wish I were one of them!I guess I was very lucky then.At lunch in the dining hall, when I was eating at a table alone, a girl came t o me.“Excuse me, is this seat taken？” she asked.I immediately shook my head.She smiled and sat down opposite to me.I felt a little awkward and didn't know what to say at all, but I really wanted to communicate with her.It was a good opportunity to make friends with her.When I looked up, I found she was smiling at me.Her smile calmed me down.“I really like this school.It's beautiful, but I don't know anyone here.All my friends went to other schools，” said the girl.Hearing her words, I immediately said, “My f riends are not here either.Can we be friends？”I was surprised.I couldn't believe I would say something like that, and to my surprise, that girl immediately said “yes”．We both smiled.We became very good friends.Now it's the beginning of a new term again.Many students may have no friends at their new schools.If you are also as shy as I used to be, please don't be afraid to talk to others.You may get a surprise and make a new friend.After all, others want to make new friends, too.7．We know on her first day at school, the author ________．A．hoped she could make some new friendsB．only knew a few people at her schoolC．met some old friends at her new schoolD．hoped she could go to her old friends' schools8．The underlined word “awkward” in Paragraph 2is closed in meaning to “________”．A．bored B．excitedC．interested D．embarrassed9．After the girl sat down opposite to the author, the author ________．A．immediately shook her handB．immediately said something to keep calmC．wanted to talk with herD．wanted her to go away at once10．What's the author's purpose in writing the passage?A．To show that high school is really exciting.B．To encourage shy people to talk to others.C．To tell us how lucky she was in high school.D．To advise us to have a good first day in high school.Ⅳ概要写作阅读下面短文，根据其内容写一篇60词左右的内容概要。
