19.One day,around Christmas time,fishermen off the west coast of Peru started on their traditional fishing trip.Much to their surprise,there were no fish!They knew immediately what had happened.Tales from years gone by had told them this was the result of El Nino which sometimes stop fishing for many months!
El Nino is a warm current that comes and goes along the west coast of South America.It got its name from fishermen in Peru more than a century ago.Every few years,they noticed a sudden warming in the normally cool Pacific water where they fished.Because this warming often came about around Christmas,they called it El Nino,which is Spanish for the"Christ Child".Generally,El Nino occurs every three to seven years and lasts only a few weeks to a month or more.
El Nino warms the water it flows through.Because the fish and sea birds need cold water to live,many of them die when El Nino comes through.El Nino also causes both floods and droughts.It is believed that El Nino may have caused the 1993Mississippi and 1995California floods.And at the same time,it may have caused droughts in South America,Africa and Australia.
El Nino has occurred thirteen times within the last fifty years,bringing natural disasters to many countries such as Indonesia and Peru.However,El Nino does not often trouble China.During this period China was badly hit by El Nino only once.In 1998,North China had a terrible drought,while South China was troubled by floods.

32.The underlined word"current"(in Paragraph 2)most probably refers to"A".
A.water  B.wind C.a(chǎn)tmosphere D.climate
33.According to the passage,which of the following is TRUE about El Nino?D
A.It happens in November and December.
B.It was named by some Spanish fishermen.
C.It only happens in South America.
D.It lasts a few weeks or more.
34.If El Nino happens,the following will take place EXCEPTB.
A.rises in temperature of the sea water
B.diseases spreading around the world
C.floods and droughts 
D.death of fish and sea birds
35.The purpose of this passage isC.
A.to discuss the prevention of El Nino 
B.to explain how El Nino trouble farmers
C.to let us know about El Nino 
D.to tell us how to prepare for El Nino.

分析 本文是一篇說明文,讓人們了解更多關(guān)于El Nino暖流現(xiàn)象的知識.

解答 32.A 詞義猜測題.根據(jù)后面that comes and goes along the west coast of South America.m沿著南美西部海灣流動.第三段第一句El Nino warms the water it flows through.El Nino使溫暖的水流過.可推知劃線單詞的意思最有可能是:水流.故選A.
33.D 細(xì)節(jié)理解題.根據(jù)最后一段最后一句El Nino occurs every three to seven years and lasts only a few weeks to a month or more.El Nino每3到7年發(fā)生一次,持續(xù)幾周到一個月或更長時間.故選D.
34.B 細(xì)節(jié)理解題.第三段第一句El Nino warms the water it flows through.El Nino使溫暖的水流過,也就是讓海水的溫度升高;排除A;根據(jù)El Nino also causes both floods and droughts.El Nino也帶來洪水和干旱.可排除C;根據(jù)Because the fish and sea birds need cold water to live,many of them die when El Nino comes through.魚和海鳥需要冷水,所以當(dāng)El Nino經(jīng)過時他們當(dāng)中很多會死去的.可排除D.故選B.
35.C.主旨大意題.縱觀全文,介紹El Nino的情況就是為了讓人們了解更多關(guān)于El Nino.故選C.

Rowan's dad was a hardworking man who wanted to give his son the best life he could.It was why Rowan's mother,Julie Van Stone,said Joseph joined the Navy and went to MIT to get two masters degrees.
While at school in Boston,he would often write to Rowan.Even when he left school and was driving back to Colorado,he would send postcards from each state he stopped in.Those postcards were sent in 2007."I remember him saying he had sent 5or 6,and I only got 3or 4in the mail.But I never thought anything of it,"Van Stone said.

4."Keep out or I'll chase you out!This is my property!"
You hear this every spring.It is a long musical sound---a bird song!Birds use their songs to communicate different messages to one another.People who study bird sounds are learning their meanings.
Usually it is the male that sings.Early in spring he sings to say that he has picked out a piece of property.He sings to attract a female of his same kind.Together they will raise a family in his territory (領(lǐng)地).He sings to tell all other birds of his kind to keep out.
Each kind of bird has its own type of song.Cardinals sing something that sounds a little like"What cheer,cheer,cheer."Towhees sing,"Drink your tea."
Most of the time,birds pay attention only to the songs of birds of their own kind.Cardinals answer cardinals,and song sparrows answer song sparrows.A cardinal knows that a song sparrow will not try to steal its mate.So you can see one reason why a cardinal may chase away another cardinal but will not bother a song sparrow.
Most different kinds of birds eat different things.To find enough to eat,a bird needs a big piece of land to search in.Many kinds of birds have some ways of dividing up the land into territories.Song sparrows,cardinals ovenbirds,and white-throated sparrows are some of the birds that have territorial systems.
Especially in early spring,birds work out the boundaries between their territories by singing"keep out"threats and by chasing and fighting each other.The birds continue singing to tell females that they have set up territories.Neighboring birds seem to agree that there are make believe fences between their pieces of property.Then they do not have to waste energy chasing each other instead of taking care of their young.
Scientists guessed that some birds could recognize their neighbors by small differences in their songs.Two scientists who studied white-throated sparrows found that these birds can even tell the difference between songs of individual birds of their own kind.White-throated sparrows have songs that seem to say"I'm your neighbor"or"I'm a stranger"or"I'm your neighbor to the west."Other kinds of birds could tell neighbors from strangers by their songs,too.

32.What is the article mainly about?B
A.How birds build up their territories.
B.How birds sing to communicate.
C.How male birds chase after females.
D.How scientists recognize birds'songs.
33.A cardinal may not keep a song sparrow out of its territory becauseC.
A.they sing different songs              
B.they have separate territories
C.it feels no threat from a song sparrow    
D.song sparrows are friendly to other birds
34.Some birds have their own territorial systems so thatA.
A.they don't need to fight or chase each other
B.they often work together against threats
C.they build up fences to protect their property
D.they find a big piece of land to search for food
35.What can we conclude from the article?C
A.Male birds use their songs to communicate more than females.
B.Scientists have learned the meanings of all white-throated sparrows sing.
C Not all birds can recognize their neighbors by small differences in their songs.
D.White-throated sparrows are the smartest birds the scientists ever found.

11.Some people think only school children do not agree with their parents,however,it is not true.
Communication is a problem for parents and children of all ages.If it's hard for you to communicate with your parents,don't worry about it.Here are some advice for you to bridge the generation gap.
Don't argue with your parents.Don't get to your parents when you are angry.Your parents probably won't consider your ideas if you are shouting at them.And you can't express yourself well if you are angry.Go someplace to cool off.Make sure you understand why you are unhappy.Then think about what you want to say to your parents.If you don't think you can speak to them at the moment,try writing a letter.
Try to reach a compromise.Perhaps you and your parents disagree on something.You can keep your disagreement and try your best to accept each other.Michael's mother didn't agree with him about buying a motorcycle.They argued over it.But they finally came to a compromise.Michael bought the motorcycle,but only drove it on certain days.
Of course,your parents might refuse to compromise on something.In these situations,it is especially important to show love and respect to them.Showing respect will keep your relationship strong.
Talk about your values.The values of your parents are probably different from those of your own.Tell your parents what you care about,and why.Understanding your values might help them see your purposes in life.
A good relationship with your parents can make you a better and happier person.It is worth having a try!
4.According to the passage who have a communication problem?D
A.parents and other people      
B.only school kids and their parents
C.teachers and their students      
D.parents and children of all ages
5.How many pieces of advice does the writer give us to bridge the generation gap?C
A.5.B.4.C.3.D.2.
6.If the values of your parents are different from those of yours,you'd betterD.
A.a(chǎn)rgue with them     
B.keep away from them
C.a(chǎn)gree with them all the time  
D.tell your parents what you care about
7.From the passage we learn thatC.
A.parents and children should not have a generation gap
B.parents should show love and respect to their children
C.there are some good ways to bridge the generation gap
D.there are so many serious problems in families today.

9.There was once a lonely girl who longed so much for love.One day while she was walking in the woods she found two starving birds.(36)E She cared about them with love and the birds grew strong.Every morning they greeted her with a wonderful song.The girl felt great love for the birds.
(37)F The larger and stronger of the two birds flew from the cage.The girl was so frightened that he would fly away.As he flew close,she grasped him wildly.Her heart felt glad at her success in capturing(捕捉) him.
(38)B She opened her hand and stared in horror at the dead bird.It was her desperate love that had killed him.

Remember,the fastest way to lose love is to hold on it too tightly;the best way to keep love is to give it wings!
