　　[00:18.34]This section is designed to test your ability to understand spoken English.

[00:25.73]You will hear a selection 1 of recorded materials

[00:30.54]and you must answer the questions that accompany them.

[00:35.03]There are three parts in this section,Part A,Part B and Part C.

[00:43.44]Remember,while you are doing the test,

[00:48.82]you should first put down your answers in your test booklet.

[00:53.71]At the end of the listening comprehension section,

[00:58.41]you will have 5 minutes to transfer all your answers

[01:03.22]from your test booklet to ANSWER SHEET I.

[01:08.21]If you have any questions,you may raise your hand NOW

[01:14.92]as you will not be allowed to speak once the test has started.

[01:20.40]Now look at Part A in your test booklet.

[01:26.02]Part A Listen and complete the sentences in questions 1-5.

[01:35.82]with the information you have heard.

[01:39.42]Write not more than 3 words in each numbered box.

[01:45.01]You will hear the recording 2 twice.

[01:48.72]You now have 25 seconds to read the questions.

[01:54.60]It has been said that farming in America today

[02:00.19]is three fourths paper work and one fourth physical labor 3.

[02:05.88]Because of this,American farmers are now able to work for more years.

[02:12.39]In the past,most were old and tired by the time they were about 40.

[02:19.18]Today,however,the average age of the American farmer is 48

[02:26.00]five years older than the average of the other American workers.

[02:31.69]Almost all new farmers in the United States

[02:36.19]have completed at least 12 years of school,

[02:40.57]and many young Americans study agriculture at a state university.

[02:46.77]The federal government provided for the establishment of these schools

[02:52.25]in a law signed by President Abraham Lincoln in 1862.

[02:59.04]Today there is a so-called land-grant university in each state.

[03:05.63]The land-grant law also created the co-operative extension service.

[03:11.92]This is a series of local offices around the country

[03:16.91]that inform farmers about the latest developments in agriculture.

[03:22.71]Extension agents test soil,give advice and answer questions.

[03:30.00]They help big farmers,small farmers,

[03:34.18]and people in cities who just want to grow some fruitsand vegetables

[03:39.09]behind their homes.

[03:41.88]In addition to the co-operative extension service ,

[03:46.38]American farmers also get information

[03:50.66]from the many agricultural publications in the Unites States.

[03:56.36]Farmers also join organization

[04:00.77]where they and their families can exchange information.

[04:05.55]Today's Agriculture Report was written by Chris Johnson.

[04:10.72]Questions 1-5 according to Part A

[04:14.90]1.Farming in American today is three-fourths paper work

[04:20.31]and one-fourth (  )labor.

[04:24.31]2.Today,average American farmers can work (  )years longer.

[04:30.11]3.Many young Americans study agriculture at a (  ) university.

[04:35.62]4.The land-grant law created the co-operative (  ).

[04:41.31]5.In 1862,the law that provided for

[04:47.01]the (   )of the agriculture schools was signed by President Abraham Lincoln.

[04:53.51]Part B Answer questions 6-10 while you. Listen

[05:02.71]Use not more than 5 words for each answer.

[05:07.51]You will hear the recording twice.

[05:11.41]You now have 25 seconds to read the questions.

[05:17.20]Now the daily Special English Science Report.

[05:24.70]Doctors say as many as 20% of all children in the United States

[05:31.39]suffer from some form of the learning disorder 4 called dyslexia.

[05:36.20]Experts on dyslexia say that the problem is not a disease.

[05:42.60]They say that persons with dyslexia

[05:46.70]use information in a different way.

[05:50.28]One of the world's great thinkers and scientists

[05:54.95]Albert Einstein was dyslexic.

[05:58.56]Einstein said that he never thought in words,

[06:02.27]he thought in pictures instead.

[06:05.66]Other famous persons who had dyslexia include Leonardo da Vinci,

[06:12.35]the American inventor Thomas Edison

[06:15.82]and former American Vice-President Nelson Rockefeller.

[06:21.00]Dyslexia first was recognized in Europe

[06:25.78]and the United States more than 80 years ago.

[06:30.79]Many years passed before doctors discovered

[06:34.58]that persons with the disorder were not mentally slow or disabled.

[06:40.48]Doctors found that the brains of persons with dyslexia are different.

[06:46.28]In most people,the left side of the brain--

[06:51.09]the part that controls language,is larger than the right side.

[06:56.68]In persons with dyslexia,the right side of the brain is bigger.

[07:02.27]Doctors are not sure what causes this difference.

[07:06.66]However,research has shown

[07:10.37]that dyslexia is more common in males than in females,

[07:15.64]and it is found more often in persons who are left-handed.

[07:20.84]No one knows the cause of dyslexia,

[07:25.13]but some scientists believe it may result from chemical changes

[07:30.93]in a baby's body

[07:35.03]Doctor Samuel Orton fifty years ago was one of the first persons

[07:40.54]to develop ways to teach persons with dyslexia.

[07:44.64]In 1940,a year after his death,doctors,teachers

[07:51.14]and other experts formed the Orton Dyslexia Society to continue his work.

[07:58.12]Doctor Silvia Richardson is a member of the Orton Society ,

[08:04.31]She says that after dyslexic persons solve their problems with language,

[08:10.11]they often show themselves

[08:13.30]to be especially intelligent or creative.

[08:17.19]She said they think differently and need special kinds of teaching help.

[08:23.17]But Doctor Richardson said

[08:26.04]it is important to help these people develop skills in every area possible.

[08:32.52]Question 6-10 according to Part B

[08:36.34]6.What kind of disorder is dyslexia?(  ).

[08:40.33]7.When was dyslexia first recognized in Europe and U.S.A.? (  ).

[08:44.93]8.In persons with dyslexia,which side of the brain is larger?(  ).

[08:49.53]9.In what kind of people can dyslexia commonly be found? (  ).

[08:57.34]10.According to Dr.Silvia Richardson,

[09:03.14]what are the characteristics of the dyslexic persons?(   )

[09:12.23]Part C You will hear three dialogues or monologues 5.

[09:19.93]Before listeningto each one,

[09:23.12]you will have time to read the questions related to it.

[09:27.69]While listening,answer each question by choosing(A)(B),(C) or(D).

[09:36.47]After listening,you will have time to check your answers.

[09:42.16]You will hear each piece once only.

[09:47.05]( 1 ) W:Exercise,exercise,exercise.

[09:54.96]We hear so much about it these days,

[09:58.54]yet even the experts can't agree on which exercises are best.

[10:04.24]Now some doctors are strongly encouraging arm exercises.

[10:09.93]M:Arm exercises? Is that because our arms are too fat or flabby?

[10:17.04]W:Actually,that's not the main reason.

[10:20.62]They say that arm exercises are an ideal way to become physically 6 fit.

[10:27.91]M:But don't arm exercises raise your blood pressure?

[10:32.79]W:That they do.But the article I read mentioned ways to compensate 7 for that

[10:39.48]M:How?W:By adding leg exercises,so the arms don't do all the work.

[10:46.09]Arm exercises alone aren't enough to increase metabolism 8 before fatigue 9 sets in.

[10:53.37]The more of the body that's involved in the exercises,the better.

[10:58.78]M:And in turn.

[11:01.08]I'm sure that there's a great chance of losing weight.

[11:05.36]W:Sounds right to me.

[11:07.85]M:So what exercises do the experts recommend?

[11:12.76]W:They mentioned quite a few,

[11:15.45]but some of the more popular ones are cycling with special bicycles

[11:20.86]that make you use both your arms and legs.

[11:24.46]And walking vigorously 10 while you wear arm weights.

[11:29.06]M:I must try that.I like to walk a lot.

[11:32.95]Questions 11-13. according to Part C (1)

[11:37.05]11.According to the conversation,what is one problem with arm exercises?

[11:41.05](A)They don't get rid of flabby arms. (B)They can damage arm muscles.

[11:45.65](C)They are not acceptable 11 to most people.

[11:50.84](D)They can raise one's blood pressure.

[11:55.13]12.How did the woman obtain the information about arm exercises?

[11:58.84](A)By talking to an expert.

[12:02.52](B)By reading an article.

[12:06.23](C)By attending an exercise class. while swing your arms back and forth 12.

[12:10.83](D)By listening to the radio.

[12:14.93]13.Which of the following exercises is suggested?

[12:19.13](A)Wearing arm weights while you are swimming.

[12:23.63](B)Jogging vigorously in one place for a long time.

[12:27.83](C)Using bicycles that require you to use both your arms arid 13 legs.

[12:32.33](D)Walking slowly while swing your arms back and forth.

[12:36.92]( 2 )The British Museum originated 14 in the private collections of Sir Hans Sloane,

[12:48.03]which he left to the nation on his death in 1753.

[12:53.62]He was a rich physician who devoted 15 his whole life

[12:58.40]to collecting curiosities from all parts of the world.

[13:03.70]These curiosities,together with George the Second's library,

[13:08.90]were reopened to the public as the British Museum in 1759.

[13:15.51]Many valuable legacies,especially private libraries and collections of art,

[13:22.19]have been left to the Museum at different times.

[13:26.48]An entire reconstruction 16 of the original building of the Museum

[13:32.38]was begun in 1828,and was finished in 1852.

[13:39.49]Within the building is a large hall,

[13:43.77]from which opens out passages and stairways to the various departments.

[13:49.67]The treasures of the British Museum are so numerous

[13:54.48]that even so large a building could not hold everything,

[13:58.97]and the scientific and zoological collections

[14:03.89]have been housed in a separate building in Kensington,

[14:08.48]known as the Natural History Museum.

[14:12.38]Within the British Museum itself housed the archaeological departments

[14:18.07]and the library,consisting of more than two million printed volumes

[14:24.37]with thousands of manuscripts 17.

[14:27.76]Questions14-16.according to Part C (2)

[14:32.15]14.What is the   origin of the   British Museum?

[14:36.36](A)The private   collection of   Sir Hans Sloane.

[14:40.95](B)The royal library   of George.

[14:44.35](C)The national   library.(D)The national   history museum.

[14:50.46]15.When was it   opened to the   public?

[14:56.16](A)in1753(B)in1759(C)in1828(D)in1852

[15:02.06]16.Where are the   scientific and   zoological   collections?

[15:08.04](A)in the British   Museum(B)in the library

[15:14.44](C)in the house of   Sir Hans Sloane(D)in the National   History Museum

[15:20.92]( 3 )Before a new airliner 18 goes into service,

[15:28.00]every part of it is tested again and again.

[15:32.49]But there are two tests that are more important than all the others.

[15:38.27]One of them is very strange and the other is very dangerous.

[15:43.26]The first of these is called the "tank test" .

[15:47.85]A model airliner must fly at very high altitudes.

[15:53.26]Air must be pumped into the plane so that the passengers can breathe.

[15:59.16]The metal structure of the plane has to be very strong for this reason.

[16:05.46]When the plane is filled with air,

[16:08.75]the air presses against the skin of the plane.

[16:12.64]The pressure on a small window,for example,

[16:16.72]is like a huge, giant foot that is trying to get out.

[16:21.60]If a small part of the plane were to crack,

[16:26.31]the plane would explode in the sky.

[16:29.81]This is what happened to the first Comets.

[16:33.70]In order to test the structure of the plane,

[16:37.80]it is lowered into a huge tank of water.Then it is filled with air.

[16:43.99]The pressure inside the plane

[16:47.39]is greater than it ever will be when it is in the air.

[16:51.88]Finally,there is an explosion.

[16:55.77]This doesn't cause so much damage inside the water tank

[17:00.58]as it would anywhere else.

[17:03.48]Engineers can discover which part of the plane cracked.

[17:08.99]This part is made stronger.

[17:11.89]The most dangerous test

[17:14.79]happens when the new plane goes through test flights in the air.

[17:20.38]The test pilot must find out exactly what happens

[17:25.29]when the engines are shut off suddenly.

[17:28.87]He takes the plane up very hight.

[17:32.55]Then he shuts the engines off.

[17:36.44]The plane begins to fall like a stone.

[17:40.23]It is the pilot's job to find out how he can get control of the plane again.

[17:46.63]These two tests are examples of how planes are made safe

[17:51.83]before they ever carry passengers.
