Question

17．Once upon a time，a boy was walking through a large woods （32）whenhe found a big blackboard hanging on an old tree trunk．It came complete with a box of chalk pieces，and bright sparks were flying from the tips of every piece of chalk．The boy took a piece of chalk and started to draw on the blackboard：first a tree，then a rabbit，and then a flower …
Magically，whenever he finished a figure，it came to life and jumped out of the blackboard．Before long，the place became a wonderfully green and fertile forest，full of animals playing happily．
（33）Excited（excite），the boy also drew his parents and brothers and sisters enjoying a picnic，with their sandwiches and cold meats．He also drew the paper plates and the empty tins of sardines（沙丁鱼） left on the ground，（34）whichalways happened on their picnics．But when these bits of litter came to life，（35）somethingawful happened：around every paper plate and every empty tin，the forest turned grey，and this greyness started spreading quickly everywhere：to the grass，to the flowers，to the animals …The boy realized the litter was （36）to blame（blame） for all the greyness，so he ran through the forest with the blackboard rubber in his hand to rub it out wherever it （37）had landed（land）．
He was quick and lucky，and didn't leave a single piece of litter．The forest and its animals managed to recover，and they played together for the rest of the day．
    The boy never again saw that blackboard，but now，every time he goes to the countryside with his family，he （38）willremember that adventure and is the first （39）to pick（pick） up any litter．And he is sure to remind the others that anything （40）left（leave） in the woods can do more damage to the environment than they ever would have expected．

分析 文章讲述了一个童话故事．一个小男孩在森林里发现了一块黑板和一盒粉笔，他好奇的在黑板上画东西．神奇的事情发生了，他画的每样东西都活了，有树木，有小兔子，有花．于是，他有画出了和家人野餐时的东西，当他画出丢弃在地上的垃圾时，周围的垃圾慢慢地多了起来．他赶紧把这些垃圾都从黑板上擦了．森林又恢复了活力．从次以后，每次外出，小男孩做的第一件事就是捡垃圾．故事告诉我们要保护好环境，不要乱丢垃圾．

解答 答案：32．when 考查连词．be doing sth when为固定句式，意为"正在做某事那时恰好发生when后面的那件事…"．
33．Exited 考查形容词．此处为形容词作状语，且表示主语感到激动，故用excited．
34．which 考查定语从句．先行词是前面的句子，且在后面的定语从句中作主语，故用which．
35．something 考查不定代词．此处代指某件事，故用something．
36．to blame 考查固定短语．be to blame for…为…负责．
37．had landed 考查时态．句中land动作发生在ran through之前，是过去的过去，要用过去完成时态．
38．will  考查动词的时态．every time引导时间状语从句时，从句用一般现在时，主句用一般将来时，故用will remember．
39．to pick 考查非谓语动词．此处在句中作定语，修饰序数词the first，故用动词不定式to pick．
40．left 考查非谓语动词．此处在句中作后置定语，修饰不定代词anything，且两者是被动关系，故用left．
