[解析]
This afternoon I went to the bookstore near my house,only∧find it was closed.
Just then,I noticed a schoolboy walking in front of me.When he passed by a white
wall,he left two footprints on it.An old man,who saw that had happened,shouted
at him angry.The boy felt afraid or ran away quickly.A few minutes later,another
boys passed by the white wall and saw the footprints.He thought for a moment and took
out of a pencil from his schoolbag.While I was wondered,I saw the boy painting the panda
on the wall.And the footprints become the panda's black eyes.What a smart boy I was!
详解:
71.only后加to 考查动词不定式 此处在句中作结果状语,表示的是意想不到的结果,应使用动词不定式形式;故在only后加to.
72.that改为what 考查连接代词 此处用来引导宾语从句,由于该从句缺少主语,意为:所…的(事情);而连词that在宾语从句中只起连接作用,不作任何成分;故用what.
73.angry改为angrily 考查副词 此处用来修饰动词shouted,故副词angrily.
74.or改为and 考查句意理解以及连词 本句的意思是:那个男孩感到害怕,便迅速跑开了;此处表示的是承接关系,而非选择关系;故用and.
75.boys改为boy 考查名词的单复数 根据形容词another可知,此处指的是另一个男孩;故用单数名词boy.
76.去掉of 考查固定搭配 take out of意为:从…取出;take out 取出,拿出;此处指的是拿出一支铅笔;故去掉a之前的of.
77.wondered改为wondering 考查句意理解时态 此处指的是今天下午发生的事情,意为:当我正在想着的时候,所以此处应使用过去进行时,故用wondering.
88.the改为a 考查不定冠词 此处用在单数名词panda之前,表示泛指一只熊猫;故用a.
79.become改为became 考查时态 此处在句中作谓语,描述的是今天下午的事情,所以应使用一般过去时;故用became.
80.I改为he 考查人称代词的一致性 此处在感叹句中作主语,指代的是那个在墙上画熊猫的男孩;故用he.
