the vase when the father said, "Now, my son, why have 小题5:．
one more try? Open your hand or hold your fingers out 小题6:

小题1:in 改为of
小题1:careless改为carelessly
小题1:正确
小题1:去掉a
小题1:why后加not
小题1:or改为and
小题1:I改为me
小题1:says改为said
小题1:Thousand改为Thousands
小题1:hold改为holding
小题1:考查of短语，of后加名词修饰前面的词，表示被修饰词具有后面词的性质，翻译成：“（具有）…的”。
小题2:只有变成副词carelessly，才能修饰后面的动词put。
小题3:正确。
小题4:固定用法。in vain，徒劳无功，白费力气。
小题5:从上下文看，这里要表达反问的含义，故应改为why not，以表达这一含义。
小题6:考查连词，and在肯定句中表示两者并列，此处父亲的意思是先open your hand再hold your fingers。
小题7:考查主格与宾格。I改成me，此处的me是前面see的宾语，所以用宾格。后面的doing不是谓语中心词，不能作为主格和宾格的依据。
小题8:say在此处与全文时态不符，当改成一致的过去时。
小题9:固定词组，thousands of和类似的词组的数词都变成复数，表示成千上万的。
小题10:固定词组，be busy doing。
