    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
    A．Culture．B．Science．C．Politics．D．Education．

    分析 本文是一篇科教类阅读，主要讲的是美国洛杉矶统一学校针对学生家庭作业方面制定的新政策及其出发点以及政策具体内容，还有批评家就此的看法．

    解答 26-30．BDABD
    26题答案：B 考查细节推理，根据文章第二段的"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"（该区希望家庭作业的限制能够使学生花更少的时间在大量的家庭作业上挣扎，有更多的时间花在爱好和家人方面）可知本题答案为B选项"有更少的家庭作业要做"．
    27题答案：D 考查细节推理，根据最后一句的"Still，L．A．Unified is joining a growing list of school districts that have set limits on the amount of homework that students receive"（而且洛杉矶统一学校加入了一个不断扩大的校区清单上--这些校区设置了学生接收家庭作业量的限制）可知本题答案为D选项"更多的学校限制了家庭作业"．
    28题答案：A 考查细节推理，根据文章第四段的"…that the right amount of homework time is ten minutes per day multiplied by the student's grade"（每天合适的家庭作业量是以年级数乘以10分钟）可知5年级的孩子合适的家庭作业量是50（5x10）分钟，故本题答案为A选项．
    29题答案：B 考查细节推理，根据Pro-homeworkteachers argue that students who do their homework perform better on tests and in school than those who do not．（Pro-homework老师辩称做家庭作业的学生比那些不做家庭的学生在考试方面表现要好）可知本题答案为B选项"认为家庭作业对学习是有用的"．
    30题答案：D 考查大意把握，本文主要讲的是学生家庭作业方面的一些新政策，这属于"教育"的范畴；故本题答案为D选项．

    3．Styrofoam，or polystyrene，is a light-weight material，about 95 percent air，with very good  insulation（隔热） properties，according to Earthsource．org．It is used in products from cups that  keep your drinks hot or cold to packaging material that protects items during shipping．
        With the above good features，Styrofoam still enjoys a bad reputation．It cannot be recycled  without releasing dangerous pollution into the air．The U．S．Environmental Protection Agency says it is the fifth-largest creator of harmful waste．
        But now the common worms which are usually disgusting can come to the rescue，specifically，mealworms．Scientists from the U．S．and China have discovered that mealworms can digest plastic．One mealworm can digest a pill-sized amount of plastic a day．Study co-author Wei-Min Wu says that in 24 hours，the plastic is turned into carbon dioxide．
       Since Styrofoam has no nutrition at all，are the worms hurt by eating plastic？Much to the scientists'surprise，the study found that worms eating Styrofoam were as healthy as worms eating bran（谷糠）．
        The researchers will study the worm's eating habits and digesting system，looking to copy the plastic breakdown but on a larger scale．Once the way can be put into practice，it will make a revolutionary difference to the disposal of plastic．
    "Solving the issue of plastic pollution is important"，says Wu，a Stanford University environmental engineering instructor．After all，our earth is small and landfill space is becoming limited with too much garbage waiting to be dealt with，he says．
        About 33-million tons of plastic are thrown away in the United States every year．Plastic plates，cups and containers take up 25 percent to 30 percent of space in America's landfills．One Styrofoam cup takes more than 1 million years to recycle in a landfill，according to Cleveland State University．

    66．What do we know about Styrofoam？C
    A．It can be used to cool drinks．
    B．It is a weightless material．
    C．It is harmful when recycled．
    D．It is usually used on ships．
    67．What can we infer from the third paragraph？A
    A．Mealworms have amazing digesting power．
    B．Mealworms are not bad in their nature．
    C．Mealworms can rescue people's lives．
    D．People misunderstood mealworms in the past．
    68．Why will researchers study the worm's eating habits and digesting system？B
    A．To find ways to help mealworms grow larger．
    B．To imitate their ways of breaking down plastic．
    C．To help develop their digesting ability．
    D．To make sure of their safety after eating plastic．
    69．In the future，plastic may be recycledD．
    A．by raising amounts of mealworms    
    B．by environmental engineering instructors
    C．using a method inspired by eating mealworms 
    D．without sending out dangerous pollution
    70．What's the main idea of this passage？C
    A．Styrofoam is widely used in daily life．
    B．Mealworms are genius at eating plastic．
    C．Plastic recycling may be no more a problem．
    D．Plastic can be turned into carbon dioxide．

    8．The pickle jar（泡菜坛），as I can remember，sat beside the dresser in my parents'bedroom．When ready for bed，Dad would toss any coins in his pockets into the jar．As they dropped，they landed with a merry jingle．
    Whenever the jar was full，Dad would roll up the coins．Every time he slid the box of rolled coins across the counter at the bank toward the cashier，he would smile proudly and say，"All for my son's college．"
    We would always celebrate each deposit by stopping for an ice cream cone．Dad would show me the coins in his change，saying"When we get home，we'll start filling the jar again．"He always let me drop the first coins into the empty jar．"You might have to get to college on loose change，"he said．"But you'll get there．"
    As years passed，I went to college，got married and took a job．

    Soon，my daughter Jessica was born．We spent Christmas that year with my parents．After dinner，Mom and Dad sat next to each other，taking turns holding their first grandchild．When Jessica began crying，my wife Susan took her from Dad's arms to put her in my parents'room．
    Susan came back，tears in her eyes and led me into the room．"Look，"she said softly．To my amazement，there，next to the dresser，stood the old pickle jar，as if never removed，the bottom already covered with coins．I walked over to it，dug down into my pocket，and pulled out several coins．Choked by emotion，I dropped them into the jar．
    Dad had slipped quietly into the room when I looked up．Our eyes locked，but neither of us spoke，because we knew nothing had to be said．

    8．Which of the following statements is TRUE？A
    A．The author and his wife were grateful for what parents had done．
    B．The jar again in the bedroom reminded themselves of the hard years．
    C．The author felt disappointed when he found the jar gone．
    D．The author felt embarrassed whenever his father mentioned the jar．
    9．We can learn from the passage thatB．
    A．any difficulty can be overcome with the family's support．
    B．parents teach much more through their action than their words．
    C．saving is always a good habit to pass down to the next generation．
    D．you need to reward yourself and celebrate regularly to keep up with your faith．
    10．Which words best describe the author's father？B
    A．Humorous and patient．
    B．Quiet but loving．
    C．Generous and talkative．
    D．Proud but strict．
    11．The pickle jar in the article representsC．
    A．advice of parents．
    B．one's purpose in life．
    C．determination to reach a goal．
    D．healthy family relations．

    18．These days，drugs can be found everywhere．Many teenagers are attracted by the excitement that drugs seem to offer，but it is important that we learn the facts about drugs．
        Some drugs are medicines．They can cure，slow，or prevent disease and help people to live healthier and happier lives，b ut there are also a lot of harmful drugs that people take to make them feel good or have a good time．
        How do drugs work？Drugs are chemicals that change the way our bodies work．When you put them into your body，the drugs find their way into your blood and are carried to parts of your body，such as your brain．In the brain，drugs may make your senses become either stronger or weaker，change your attitude or even reduce the feeling of physical pain．Some drugs can seriously damage a person's ability to make certain choices and decisions．
        However，some teenagers believe drugs can help them think better，become more popular，or stay active for longer．Many teenagers use drugs because they are unhappy or think drugs will help them escape their problems．The truth is that drugs cannot solve problems．When you use drugs，it simply helps you to hide from your feelings and problems．When a drug wears off，the feelings and problems that bother you will still remain-or even become worse．Harmful drugs can destroy a person's life．Some drugs are hig hly addictive．Even if you use them once，they can cause an addiction that makes it very，very difficult for users to stop．

    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 （留声机）
    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 （铝箔）．People could listen to them only a few times before the foil broke．Later the music was on wax cylinders （蜡筒）．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 （便携式的） 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．
