3.People all over the world love listening to music and most have their favourite songs which they listen to again and again.But how did it all start?When could people first choose the music they wanted to listen to?
The 1900s:The player radio
In the late 19th and early 20th centuries,pianos became very popular and rich families bought"player pianos".A player piano played music that was programmed on paper rolls with holes in them and you could also play it like a holes in them and you could also play it like a"normal"piano.In the mid 1920s player pianos began to disappear mainly because the radio got more popular.
The 1910s:The first phonographs (留聲機)
As early as 1877,there were phonographs to play music on and by the 1910s,many families had one.The music was on"records"made of aluminum foil (鋁箔).People could listen to them only a few times before the foil broke.Later the music was on wax cylinders (蠟筒).There could hold longer recordings (two to four minutes),and people could play them more often.
The 1920s:Gramophones and record players
Gramophones were similar to the phonographs,but they used flat vinyl (乙烯基) disks and not cylinders to hold the music.The disks went round,and first a steel needle,then later a small diamond,"took"the music off the record.Some of the disks could play for more than 20minutes per side.Today some music lovers who are crazy about disks still use vinyl records.
The 1960s-1970s:Cassettes and the Walkman
In the 1960s,the first cassette recorders became popular.A big step towards modern technology was the invention of the first portable (便攜式的) cassette player,the"Walkman",by the Japanese company,Sony in 1979.For the first time,people could listen to their favourite music while they were travelling,doing sports,or going for walks.
21.What happened to the player piano in the mid 1920s?C
A.Only the rich could afford it.
B.It began to be used as a"normal"piano.
C.It was gradually replaced by the radio.
D.It was improved and played music automatically.
22.What do we know about phonographs and gramophones?A
A.They used different records to hold the music.
B.They are still popular among music lovers now.
C.Gramophones were easier to carry than phonographs.
D.Phonographs held longer recordings than gramophones.
23.The text is mainly aboutD.
A.the history of music.
B.the popularity of music.
C.the different types of music.
D.the development of listening to music.

13.How important is homework?According to the Los Angeles Unified School District (LAUSD),it's not that important!The district has made a big change for the 2013-2014 academic school year.Starting July 1,homework will count for only 10% of a student's academic grade.
The district hopes the limit on homework will allow students to spend less time struggling with large am ounts of work and more time on hobbies and with their families.Besides,the policy states,"by limiting the weight of homework toward a student's grade,a truer picture of the student's knowledge will be reflected in the achievement grade."
The new policy doesn't remove homework.It states that homework is an opportunity for students to practice their skills and a tool for students to prepare for upcoming lessons.Still,L.A.Unified is joining a growing list of school districts that have set limits on the amount of homework that students receive.
Exactly how much time kids should spend on homework is a topic for debate.Harris Cooper,a professor at Duke University,says that the right amount of homework time is ten minutes per day multiplied by the student's grade.This means a third grader should spend 30 minutes per day on homework.And a sixth grader would spend 60 minutes.Five years ago,Cooper wrote about his views in TFK."Good homework assignments in the proper amount will have positive effects,"he wrote."Bad homework assignments,or too much homework,will have negative effects."
Critics of the new L.A.district policy say that homework is an important part of learning.They say many kids just won't put in the effort if homework doesn't count toward their grade.Pro-homeworkteachers argue that students who do their homework perform better on tests and in school than those who do not.They fear that the new policy will enc ourage students to neglect homework assignments.

26.In the 2013-2014 academic school year the students in LAUSD willB.
A.work harder on their lessons
B.have much less homework to do
C.be able to do whatever they like
D.spend more time on homework
27.We can learn from Paragraph 3 thatD.
A.homework is of no use at all
B.studnets should do more homework
C.students all are happy to do homework
D.more school districts limit homework
28.If you are a student of fifth grade,the proper amount of homework isAminutes.
A.50        B.30         C.60          D.10
29.Pro-homework teachers probably refer to thoseB.
A.that suggest reducing the amount of homework
B.that think homework is helpful to the students
C.that insist increasing the students'homework
D.that are good at encouraging the students
30.What does this passage mainly talk about?D

11.By 1938,Europe had been experiencing an increased number of attacks on Jews.With no end in sight,Jewish refugee(難民) agencies requested the British government to allow them to bring in only Jewish children under17years of age.This was to be only temporary,until the situation in their home countries was improved.
Kindertransport,meaning"children transport"in German,was then born.Children from Germany,Austria,Czechoslovakia,Poland and other Nazi-occupied regions were transported to the United Kingdom.There they were either placed with other families or in hostels.Later,it was found that many of these children were the only survivors of their families.Nicholas Winton was among those people who helped to save Jewish children.He managed to rescue 669children from Czechoslovakia and bring them safely to England.In 1938around Christmas,29-year-old Nicky was about to leave for a skiing holiday.Suddenly,Martin Blake,one of his good friends,contacted(聯(lián)絡(luò)) him from Czechoslovakia,asking him to travel there to help political refugees on the run from the Nazis.And Nicholas agreed.
Nicky spent his entire holiday of 3weeks in the capital city of Prague where he saw the situation first-hand.Once back in England,he immediately started organizing the evacuation(撤離) of children from the Czech region.From advertising for the necessary permits,Nicky worked tirelessly.By August 1939,669children had been helped by Nicky and his friends. Haplessly,the last group of children due to leave Prague in the beginning of September could not do so-World WarⅡbroke out,and swallowed them up.
Nicky did not discuss his particular task with his wife,Grete.It was only when she found a scrapbook in 1988,with names of the rescued children,their (lost) parents and the foster families that had taken them in,that his heroism came to light.Nicky has received several awards in Britain and the Czech Republic.
29.Kindertransport aimed toD.
A.help the homeless
B.transfer the affected
C.stop German attacks
D.save Jewish children
30.We can learn from the text that Nicholas WintonB.

C.a(chǎn)lways told his wife what he was doing
D.saved 669 children and their parents
31.The underlined word"Haplessly"in Paragraph 4can best be replaced by"A".

18.Living in a foreign culture can be exciting,but it can also be confusing (令人迷惑的).A group of Americans who taught English in other countries recently discussed their experiences.They decided that miscommunications were always possible,even over something as simple as"yes"and"no".
On her first day in Micronesia,an island in the Pacific,Lisa thought people weren't paying any attention to her.The day was hot.She went into a store and asked,"Do you have cold drinks.The woman there didn't say anything.Lisa repeated the question.Still the Woman said nothing.She later learned that the woman had answered her:She had raised her eyebrows (眉毛),which in Micronesia means"yes".

15.There are two factors (61)determining(determine) an individual's intelligence.The first is the sort of brain he is born(62)with.Human brains differ considerably,some being more capable than others. (63)Buthowever good a brain he has to begin with,an individual will have a low intelligence unless he has(64)opportunities(opportunity) to learn.So the second factor is what happens to the individual-the sort of environment(65)wherehe is brought up.If an individual is handicapped(受阻礙)environmentally,it is(66)likely(like)that his brain will fail to develop and he will never reach the level of intelligence of which he is capable.
The importance of environment in determining an individual's intelligence can be shown by(67)thecase of the twins,Peter and Mark.When the twins were three months old,(68)theirparents died,and they were placed in separate foster homes.Peter was brought up by parents of low intelligence with poor educational opportunities.Mark was educated in the home of well-to-do parents who(69)had been(be) to college.This environmental difference continued until the twins were in their late teens,when they(70)were given(give) tests to measure their intelligence.Mark's I.Q.was 125,twenty-five points higher than the average and fully forty points higher than his twin brother.

13.The role of a newspaper is to present and comment on the news.It is vital for keeping people well-informed on current affairs.In most Western countries,journalists try to shape the ideas and opinions of their readers,since in Western countries all newspapers are independent of the government.Some newspaper owners support liberal ideas including economic policies that help poor people.Other owners want policies such as lower taxes for rich people and less money to be given to poor people.You can almost judge the political ideas of a person in the West by looking at the newspaper he reads.
All newspapers report national and international news.They give the facts but also provide opinions on controversial issues in the editorials and columns of opinion.The readers of the newspaper can also comment on these editorials or articles.There are many informative articles too as well as reviews of new films and books,etc.These are very important,for if a film or book gets good reviews it will often become more successful.
All these articles require many journalists who are experts in different areas of life.All these articles come together and are checked by the chief editor of the newspaper.When he or she has made a decision on the articles,the newspaper is prepared for printing.All this work means that the journalists must work together as a team because there is a lot of pressure when you work in a newspaper office.There are constant deadlines and articles have to be fitted round advertisements,photographs and much,much more.

44.What does the underlined word"be fitted"mean?B.
A.be suitable
B.be put
C.be read
D.be measured
45.What articles comment on controversial issues?A.
A.Editorials and opinion columns.
B.News stories.
C.Some of the informative articles.
D.Jokes and humour.
46.Which is true about the journalists in Western countries?D.
A.There's no time limit for their report articles.
B.They have no right to influence the readers'opinions.
C.A newspaper can come out with just a journalist working individually.
D.Journalists must submit their articles before the due date.
47.Why are good reviews important to books?D.
A.Good reviews are excellent introduction to books.
B.Readers especially favour books with good reviews.
C.Good reviews can make readers feel relaxed and comfotable.
D.Good reviews can bring a large circulation of the books reviewed.
