8．I was called to examine a dog named Belker．Its owners，and their little boy，Shane，loved Belker．
I found he was dying of cancer．I said we couldn't save Belker，and offered to perform the euthanasia．
As we made arrangements，the parents told me they thought（61）itwould be good for six-year-
old Shane to observe that．They felt as though Shane might learn something from the experience．The
next day，Shane seemed so calm，（62）petting（ pet ） the old dog for the last time，（63）thatI
wondered if he understood what was going on．Soon Belker（64）died（ die ） peacefully．The little boy seemed to accept Belker's death without（65）difficulty（ difficult ）．We sat together after Belker's death，talking about the sad fact that animal lives are （66）shorter（ short ） than human lives．Shane，who had been listenng（67）quietly（ quiet ），said，"I know why．"（68）surprised（surprise），we all turned to him．What came out of his mouth stunned me．I'd never heard a more comforting（69）explanation（ explain ）．He said，"People are born so that they can learn（70）howto live a a good life-----like loving everyday all the time and being nice，right？"The six---year---old boy continued，"Well，dogs already know how to d that，so they don't have to stay as long．"
分析 本文写了给一只小狗安乐死的故事，同时也教育了狗的小主人如何面对生活中的痛苦．
解答 1．it 考查代词．根据上下文连词，这里的it 指的是我想帮助Belker这件事．
2．petting 考查非谓语．Shane与动词pet之间是主谓关系，所以用现在分词在句中做伴随状语．
3．that 考查固定句型．so…that是英语中固定句型"如此…以至于…"．他如此平静以至于我想知道他是否明白了…，所以用that．
4．died 考查时态．本故事的叙述是用过去时，所以此处也是过去时．
5．difficulty 考查名词．介词without后跟名词，所以答案是名词difficulty．
6．shorter 考查比较级．在固定句型 than的前边必须用形容词的比较级来表达比较．
7．quietly 考查副词．此处用副词修饰动词listen，安静地听着．
8．surprised 考查形容词．此处是用形容词做伴随状语，我们回头转向他，非常惊讶．
9．explanation 考查名词．此处填写的是heard的宾语，所以用名词explanation．
10．how 考查固定用法．疑问词+to do 可以在句中做宾语，句意：他们可以学到如何过幸福的生活．
