For many years,Indian rhinos were in great danger.People hunted them for their horns,which were used in traditional medicine.Farmers also took over their land for farming.By the early 1900s,fewer than 200 Indian rhinos remained.Luckily,the governments of India and Nepal made laws to protect them.They set up national parks and punished hunters.Thanks to these efforts,the number has increased to over 3,700 today However,the rhinos still face problems.Climate change is making their habitats drier. Invasive plants are replacing the food they eat.And some people still hunt them illegally.If we want to save the Indian rhino,we need to stop using rhino horns and protect their homes.Every small action can make a big difference. ()1.What is special about the Indian rhino compared to African rhinos? A.It has thicker skin. B.It has only one horn. C.It lives in swamps. D.It eats different food. ()2.Why were Indian rhinos in great danger many years ago? A.Because farmers protected their land. B.Because people hunted them for horns. C.Because there were too many rhinos. D.Because the climate became too cold. ()3.What helped the rhino population increase to over 3,700? A.Farmers offering them food. B.People moving to other places C.Government laws and national parks. D.Climate change making land wetter. ()4.What problem do Indian rhinos still face today? A.They have no food at all. B.Their horns are no longer useful. C.Some people still hunt them illegally. D.They cannot live in national parks. ()5.What is the best title for this passage? A.How to Protect Rhino Horns B.The Indian Rhino:Past and Present C.African Rhinos vs.Indian Rhinos D.A Letter from a Rhino B篇 Did you know that elephants can "talk"to each other from far away?They use sounds that humans cannot hear.These low-frequency sounds,called infrasound,can travel through forests for several kilometers.Scientists have discovered that elephants use infrasound to warn each other about danger,find a mate,or tell the herd where to find water. Elephants also communicate with their bodies.When an elephant flaps its ears,it might mean it is angry or excited.A gentle touch with the trunk is a way of saying hello.Mother elephants use soft rumbles to comfort their babies.If a baby gets lost,it will make a high-pitched call,and the whole herd will answer. But elephants are in trouble.In Asia and Africa,people hunt them for their ivory tusks. Habitat loss is another problem.As forests are cut down,elephants have less space to live and find food.Today,there are only about 40,000 Asian elephants left in the wild. Many countries have banned ivory trade,but illegal hunting continues. Some organizations are working hard to save elephants.They use cameras to watch for hunters and help local people find other ways to make money.Scientists are also studying elephant communication to better protect them.If we want to keep these amazing animals on Earth,we need to act now. ()1.What is infrasound? A.A very loud sound that humans can hear. B.A low-frequency sound that travels far. C.A sound made only by baby elephants. D.A sound that elephants use to find food. ()2.How do elephants communicate besides using sounds? A.By waving their trunks. B.By using body movements and touch. C.By making high-pitched calls only. D.By flapping their ears to say hello. ()3.Why are elephants in danger according to the passage? A.Because they cannot make infrasound. B.Because people hunt them for ivory and destroy their homes. C.Because they have too many babies. D.Because scientists study them too much. ()4.What can we infer from the last paragraph? A.Elephants are no longer in danger. B.Scientists have already saved all elephants. C.People are trying different ways to protect elephants D.Cameras can stop all illegal hunting. ()5.Where would you most likely read this passage? A.In a travel guide. B.In a science magazine C.In a storybook. D.In a sports newspaper. 二、完形填空 A long time ago,a lion was sleeping in the forest.A small mouse ran across his nose and woke him up.The lion was very angry and caught the mouse."I'll eat you!"he shouted."Please don't eat me!"cried the mouse."If you let me 1.,I will help you someday."The lion laughed."How can a tiny mouse help a big lion?"But he let the mouse go.

I think we should take action right now.First,the government should make stricter laws against hunting.Second,we should create more nature reserves where animals can live safely.Third,we can help by not buying products made from animal fur or bones. I also believe that education is important.If children learn to love and respect wildlife, they will grow up to protect it.Our school has started a "Wildlife Club".We put up posters and give talks to other students.I hope more schools will do the same. Yours sincerely, Li Ming 1.Why does Li Ming write this letter? 2.What are the two reasons why snow leopards are in danger?
