解析
小题1:a 8-year-old son改为an 考查冠词。一个八岁的孩子，eight是元音开头，故用an.
小题2:bought a piano to Tony改为for 考查动词。Buy sb sth 等于buy sth for sb ,给某人买某物。
小题3:he can become改为could 考查情态动词。表示对将来的虚拟，所以改为could.
小题4:put her heart改为his 考查人称代词。Put one’s heart into doing 全心投入做某事，主语是小男孩，所以用他的，his.
小题5:seemed enjoy every minute在seemed后加to 考查动词。句意：他好象很享受每一分钟。Seem to do 好象做某事。
小题6:he was tiring改为tired 考查形容词。句意：他告诉他的父亲他厌倦了弹钢琴。Be tired of 厌倦了某事。
小题7:Heard this改为Hearing 考查非谓语动词。句意：听到这，史密斯先生说。两个句子共用一个主语，主动用doing来表达。
小题8:and it is another thing改为but 考查连词。句意：喜欢听音乐是一回事，而独立优美的表演又是另外一回事。两个句子之间表示转折，故用but.
小题9:perform skillful改为skillfully 考查副词。句意：你自己弹的好又是另外一件事。修饰动词perform用副词形式。
小题10:well even if去掉even考查连词。句意：如果你多加练习，你不能弹好。Even if 即使，if 如果，两个句子是条件关系，故去掉even。
考点
据考高分专家说，试题“Mr. Smith had a 8-ye.....”主要考查你对 [序数词 ]考点的理解。序数词
序数词的概念：
表示顺序的数称为序数词。如：first, second, third, fourth。
序数词的构成与用法：
1、序数词的构成：
①一般来说，是由相应的基数词加词尾th构成。
例：four＋th→fourth
six＋th→sixth
seven＋th→seventh
ten＋th→tenth
②下面这些基数词在变为序数词时，有特殊的变化。
例：one→first
two→second
three→third
five→fifth
eight→eighth
nine→ninth
twelve→twelfth
③十位整数序数词的构成方法是将基数词的词y变成i，然后再加eth。
例：twenty→twentieth
thirty→thirtieth
forty→fortieth
ninety→ninetieth
④两位或两位以上的基数词变成序数词时，仅将个位数变成序数词。
例：twenty－one→twenty－first
thirty－five→thirty－fifth
a hundred and fifty－three→a hundred and fifty－third
2、序数词的用法：
①序数词在使用时，一般加上定冠词。
例：the first book
the second floor
the third day
the fourth week．
②序数词在多数情况下都用作定语，有的也可以作表语、主语和宾语。
例：The may1st is Labour Day. 五月一日是劳动节。
My room is on the second floor. 我的房间在二楼。
The first is larger than the secon.（主语）第一个比第二个大。
Read the book from the first.（宾语）从开头读这本书。
You'll be the sixth to write.（表语）你将是第六个写的。
③序数词的前面可以加上不定冠词，用来表示“再一”，“又一”的意思。
例：You may have a third try. 你可以第三次尝试。
序数词知识体系：
约数的表达方法：
用tens/dozens/scores/hundreds/thousands/millions of 表示“几十、几百、上千、成千上万”等。
如：The boy bought dozens of pencils.
Thousands of people died in the earthquake.
注意： (A)：dozen, score, hundred, thousand, million等表示确切数量时，不用复数。
如：five dozen (of) eggs 五打鸡蛋
hree hundred people 三百个人
分数词的构成和用法：
1）分数词构成法：
分数词（FractionalNumerals）由基数词和序数词构成，基数词代表分子，序数词代表分母。除了分子为1的情况下，序数词都要用复数形式：
如：1/4：one-fourth
5/9：five-ninths
2/3：two-thirds
17/5：three and two-fifths
7/12：seven-twelfths
379/8：forty-seven and three-eighths
此外还有下面表示法：
如：1/2：a(one) half
1/4：a(one) quarter
3/4：three-quarters
9/4：two and a quarter
3/2：one and half
31/4：seven and three quarters
