保护野生动植物恐龙因一次意外事件而灭绝，但是今天的野生动植物却是因为人类的伤害而消失或处在危险中。

例如，老虎被猎杀以获取做地毯的皮毛，以致它们只能生活在安全的保护区里；草地被毫不怜悯地破坏，以致沙尘暴开始影响遥远的城市。

去年，科学家观察到猴子在身上擦某种昆虫来保护自己不受凶猛的蚊子的叮咬。

根据检查的结果，他们发现这种昆虫含有一种具有强大效力的药物，于是，当地的农民都被雇来抓虫子。

结果是，这种昆虫从这整个地区都消失了。

当被告知说这是整个人类的损失时，农民们都突然大笑着回应道：“我们减少的收入才是我们真正的损失呢！”我们应该意识到自然平衡的重要，更加注意野生动植物的保护。

直到我们成功让野生动植物安详平静地生活，我们自己才能如释重负地笑开颜。

In fact, about 96 percent of those surveye d said people with a sense of humor do better.The survey went on to point out that the results suggest that a sense of humor may help light­hearted employees k eep their jobs during tough times. And, what's more, it may pushthem up the corporate ladder past their humorless colleagues. Why? It seems that those with a sense of humor are better communicators and better team players.Studies have shown that happy workers are more productive. In fact, a researcher at California State University found that humor could help the employees to release tension. Research done by psychologist Dr. Ashton Trice at Mary Baldwin College in Virginia showed that humor helps us think. When people feel stuck on important projects, they tend to feel angry or depressed. According to Dr. Trice's research, taking time out to laugh can help us to get rid of negative feelings and allow us to retur n to a task or move on to another project unaffected by past defeat.If humor is really this important, then why don't we use it more often on the job? Most likely, the main reason is that many people are unaware of the positive effects of humor in the workplace. However, it is important to realize that some humor is not suitable for the workplace, and that it is often used at wrong times.1. Most people think a sense of humor can ________.A. help you to do your work betterB. make you have a rich lifeC. make you pleased with your workD. help you to make more friends2. Many people don't use humor more in the workplace because ________.A. they like keeping silent when workingB. they don't know the positive effects of humorC. they think they should obey the rulesD. they don't like joking or laughing3. A person without a sense of humor is easier ________.A. to feel surprisedB. to get along withC. to be worriedD. to be successful4. What is probably the best title for the article?A. People with a Sense of HumorB. Humor Is Important in the WorkplaceC. Humor and HumorlessD. Everyone Likes Humor题二十：Several times my daughter had tel ephoned to say, “Mum, you must come and see the daffodils (水仙花) before they are over.” I wanted to go, but it was a two­hour drive from Lake Arrowhead. “I will go next Tuesday,” I promised, a little unwillingly, on her third call.The next Tuesday dawned cold and rainy. Still, I had promised, and so I drove there. When I finally walked into Carolyn's house and hugged and greeted my grandchildren, I said, “Forget the daffodils, Carolyn! The road is invisible (看不见的)in the cloud and fog, and there is nothing in the world except you and these children that I want to see！”My daughter smiled calmly and said, “We drive in this weather all the time, Mum. You will never forgive yourself if you miss this experience.”After abo ut twenty minutes, we turned onto a small road and I saw a small church. On the far side of the church, I saw a hand-lettered sign that read “Daffodil Garden”.We got out of the car and each took a child's hand, and I followed Carolyn down the path. Then, we turned a corner of the path, and I looked up and gasped. Before me lay the most beautiful sight! There were five acres of flowers! “But who has done this？” I asked Carolyn. “It's just one woman,” Carolyn answered. “That's h er home,” C arolyn pointed to a well-kept A-frame house that looked small and modest in the midst of all that glory. We walked up to the house. On the patio (庭院), we saw a poster. “Ans wers to the Q uestions I Know You Are Asking” was the headline.The first answer was a simple one. “50,000 bulbs (鳞茎),” it read. The second answer was, “One at a time, by one woman.” The third answer was, “Began in 1958.”I thought of this woman whom I had never met, who, more than fifty years before, had begun — one bulb at a time — to bring the beauty and joy to the mountain top.1. The author didn't go to see the daffodils at first because ________.A. she was not interested in themB. they were growing on the mountain topC. the weather was not good enoughD. it was not easy for her to drive there2. What do we know about the woman living in the A-frame house?A. She must be out of mind.B. She acted as a gardener there.C. It took her great determination to grow the daffodils.D. She was poor and made her living by selling daffodils.3. What could the author probably learn from this experience?A. Nothing is too difficult if you put your heart into it.B. We must put the interests of others above our own.C. We can change the world by growing flowers.D. It's never too late to learn.4. W hat would be the best title for the passage?A. An Unforgettable ExperienceB. Beautiful DaffodilsC. One Bulb at a TimeD. I Love DaffodilsUnit4 Wildlife protection(二)课后练习参考答案题一：D解析：本句意为：据报道现在在灾区许多新房子正在被建造。

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。

Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.Why should people care? Because we need animals. And because once they are gone, there will never be any more.Animals are more than beautiful or interesting or a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems.For example, when farmers killed large numbers of hawks (鹰), the farmers' stores of corn and grain were destroyed by mice. Why? Because hawks eat mice. With no hawks to keep down their numbers, the mice multiplied quickly.Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger.Quite a few countries have passed laws. These laws forbid the killing of any animal or plant on the danger list. Slowly, the number of some animals in danger is growing.【文章大意】本文是一篇关于动物保护的说明文。

Ⅱ.阅读理解You probably know that frogs hop.But did you know that there's a small frog in the Pacific Northwest that bellyflops(肚子先落水)? It's called a tailed frog.Dr Rick Essner, who has been studying tailed frogs for the past few years, says, “ I've looked atthousands of jumps and have never seen them land on their feet like other frogs.” Most of the time, tailed frogs land on their stomachs and then bring their back legs in to prepare for another jump.Essner first noticed these frogs because of the way they swim.Other frogs kick both of their back legs at the same time.But when a tailed frog swims, it pushes first with one leg and then the other.To try to find out why tailed frogs bellyflop, Essner and other scientists collected and filmed different kinds of frogs.They found that all of the frogs start their jumps the same way: they hold out their legs.The change comes in the landing.Tailed frogs can't move their back legs as quickly as other frogs do.Maybe they don't need to.Tailed frogs live around water and quickly jump into the water to escape danger.Early frogs developed around watery areas and could jump quickly into the water to escape danger.Scientists think those frogs blended in with (与……融合在一起) the green plants on the side of the rocky rivers, just like today's tailed frogs.“Ι would guess that other animals would have problems detecting them, ” explains Essner.When other animals find those early frogs, t he frogs could jump into the river.They didn't need to continue hopping.Tailed frogs and other kinds of frogs went their own ways about 200 million years ago.Tailed frogs stayed by rivers.Other kinds of frogs moved to places where new hopping skills allowed them to survive.1．What's special about the tailed frog?A．It has a long tail.B．It jumps on one foot.C．It starts its jump differently.D．It lands differently from other frogs.2．Why do tailed frogs bellyflop?A．They have never left the water to live.B．They have trouble in holding out their legs.C．Their back legs can't catch up while jumping.D．Their front legs develop better than the back ones.3．The underlined word “detecting” in Paragraph 5 means “________”．A．eating B．killingC．using D．discovering4．When they are in danger, the tailed frogs would ________．A．jump into the water for protectionB．hop around quicklyC．hide in the green plants near the riverD．jump into the rocksⅢ.写作第一节应用文写作请你以李华的名义给China Daily写一封信，倡议人们保护野生动物。
