    12．The issuebeing discussed （discuss） at the meeting now is of great importance．

    分析 此刻会议上正在讨论的问题很重要．

    解答 答案是being discussed．本题考查非谓语动词做定语，题干中需要的是the issue的定语，故用非谓语的形式做定语：动词不定式作定语表示将来；现在分词表示进行；过去分词表示被动和完成；由题干中的时间状语now判断用现在分词做定语；此外the issue和discuss 之间是被动关系，故需要用现在分词的被动语态，因此答案是being discussed．

    点评 本题是要求用所给词的适当形式填空，解题时首先根据句子的结构考虑句中需要的词性；其次，关注所选词的形式的变化：如果是谓语动词关注时态、语态和数的变化；如果是非谓语动词要联系非谓语的基本用法判断非谓语的形式．如果是名词关注单数和复数的选用等．

    2．I am a strong believer that if a child is raised with approval，he will learn to love himself and will be successful in his own way．
    Several weeks ago，I was doing homework with my son in the third grade and he kept standing up from his chair to go over the math lines．I kept asking him to sit down，telling him that he would concentrate better．He sat but seconds later，as if he didn't even notice he was doing it，he got up again．I was getting frustrated，but then it hit me．I started noticing his answers were much quicker and accurate （准确的） when he stood up．Could he be more intent （专心的） while standing up？
    This made me start questioning myself and what I had been raised to believe．I was raised to believe that a quiet，calm child was a sure way to success．This child would have the discipline （纪律） to study hard，get good grades and become someone important in life
    Now those same people perhaps come to realize that their kids are born with their own sets of DNA and personality traits （特点） and all you can do is loving and accepting them．As parents，throughout their growing years and beyond that，we need to be our kids'best cheerleaders，guiding them and helping them find their way．
    I have stopped asking my son to sit down and concentrate．Obviously，he is concentrating just in his own way and not mine．We need to learn to accept our kids'ways of doing things．Some way may have worked for me but doesn't mean we need to carry it through generations．There is nothing sweeter than being individual （个人的） and unique （独一无二的）．It makes us free and happy and that's just the way I want my kids to live their own life．
    63．At the beginning，the author tried to keep his son seated in order to make himA．
    A．pay more attention to his study     
    B．keep silent in the room
    C．finish his homework on time    
    D．get right answers
    64．Inspired by the case of his son，the author began to doubtB．
    A．the importance of parents               
    B．the old form of education       
    C．the relationship between kids and their parents         
    D．the good grades of some kids
    65．According to the passage，which of the following statements is right？D
    A．We should help kids correct their wrong ways．
    B．Parents should study their kids'DNA．
    C．Kids should be taught to behave themselves．
    D．Parents should love and accept their kids．
    66．Which of the following would be the best title of the passage？C
    A．Study hard and you'll be successful           
    B．Be friendly to your children
    C．Children's success in their own style     
    D．Parents'help with their children's study．

    1．Call it the learning paradox：the more you struggle and even fail while you're trying to learn new information，the better you're likely to recall and apply that information later．
    The learning paradox is at the heart of"productive failure，"a phenomenon identified by researcher Manu Kapur points out that while the model adopted by many teachers when introducing students to new knowledge providing lots of structure and guidance early on，until the students show that they can do it on their own makes intuitive sense，it may not be the best way to promote learning．Rather，it's better to let the learners wrestle with the material on their own for a while，refraining from giving them any assistance at the start．In a paper published recently，Kapur applied the principle of productive failure to mathematical problem solving in three schools．
    With one group of students，the teacher provided strong"scaffolding"--instructional support and feedback．With the teacher's help，these pupils were able to find the answers to their set of problems．Meanwhile，a second group was directed to solve the same problems by cooperating with one another，without any prompts from their instructor．These students weren't able to complete the problems correctly．But in the course of trying to do so，they generated a lot of ideas about the nature of the problems and about what potential solutions would look like．And when the two groups were tested on what they'd learned the second group"significantly outperformed"the first．
    The apparent struggles of the floundering （挣扎的） group have what Kapur calls a"hidden efficacy"：they lead people to understand the deep structure of problems，not simply their correct solutions．When these students encounter a new problem of the same type on a test，they're able to transfer the knowledge they've gathered more effectively than those who were the passive recipients of someone else's expertise．
    In the real world，problems rarely come neatly packaged，so being able to discern their deep structure is key．But，Kapur notes，none of us like to fail，no matter how often Silicon Valley entrepreneurs praise the beneficial effects of an idea that fails or a start-up company that crashes and burns．So we need to"design for productive failure"by building it into the learning process，Kapur has identified three conditions that promote this kind of beneficial struggle．First，choose problems to work on that"challenge but do not frustrate．"Second，provide learners with opportunities to explain and elaborate on what they're doing．Third，give learners the chance to compare and contrast good and bad solutions to the problems．And to those students who protest this tough-love teaching style：you'll thank me later．

    61．Why does the author call the learning process a paradox？C
    A．Pains do not necessarily lead to gains．
    B．What is learned is rarely applicable in life．
    C．Failure more often than not feeds success．
    D．The more is taught，the less is learned．
    62．What does Kapur disapprove of in teaching？C
    A．Asking students to find and solve problems on their own．
    B．Developing students'ability to apply what they learn．
    C．Giving students detailed guidance and instruction．
    D．Allowing students a free hand in problem solving．
    63．What do people tend to think of providing strong scaffolding in teaching？B
    A．It will make teaching easier．
    B．It is a sensible way of teaching．
    C．It can motivate（激发） average students．
    D．It will build up students'confidence．
    64．What kind of problem should be given to students to solve according to Kapur？D
    A．It should be able to encourage cooperative learning．
    B．It should be easy enough so as not to frustrate students．
    C．It should be solvable by average students with ease．
    D．It should be difficult enough but still within their reach．
    65．What can be expected of this tough-love teaching style？A
    A．Students will be grateful in the long term．
    B．Teachers will meet with a lot of resistance．
    C．Parents will think it too harsh on their kids．
    D．It may not be able to yield the desired results．

    2．Light travels at a speed which is about a million times faster than the speed of sound．In one second，light travels about 300，000km，but sound travels only 344m．You can get some idea of this difference by watching the start of a race．If you stand some distance away from the starter，you can see smoke come from his gun before the sound reaches your ears．This great speed of light produces some strange facts．Sunlight takes about 8minutes to reach us．If you look at the light of the moon tonight，remember that the light rays（光线）left the moon 1.3seconds before they reached you．The nearest star is so far away that the light which you can see from it tonight started to travel towards you four years ago at a speed of nearly 2million km per minute．In some cases（在某种情况下）the light from one of tonight's stars started on its journey to you before you were born．
    Thus，if we want to be honest，we cannot say"The stars are shinning tonight．"We have to say，"The stars look pretty．They were shining four years ago but their light has only just reached Earth．"

    41．If you stand 200meters away from a man who is firing a gun to start a race，you will find out thatB．
    A．you can hear the gun before you see the smoke．
    B．sound does not travel as fast as light．
    C．the sound of the gun will reach you before the man fires his gun．
    D．sound travels about a million times faster than light．
    42．Sunlight clearlyA than the light of the moon．
    A．has to travel a greater distance
    B．moves less quickly
    C．travels much more quickly
    D．is less powerful
    43．What does"it"in the second paragraph refer to？C
    A．moon light    
    B．light rays  
    C．the nearest star   
    D．the moon
    44．The scientific way of saying"The stars are shining tonight"should beC．
    A．the  stars have been shining all the time．
    B．the  stars seen tonight will be shining four years later．
    C．the  stars were shining long ago but are seen tonight．
    D．the  starlight seen today could be seen four years ago．
    45．The light of the nearest star you see tonight has beenD for years．
    A．on the earth              
    B．on the moon
    C．away from the sun   
    D．away from the star．
