解析
文章介绍汤姆是个勤奋的学生，周末都不休息，但是因为太疲劳效果不好，爸爸建议他好好休息一下，全家人到郊区野餐，放风筝，玩得很愉快，星期一，汤姆也能精力充沛的上课。
小题1:汤姆是个高二学生，因为是单数，所以students改成student
小题2:在晚上，他在家学习到深夜。因为是上个星期六的事情，用一般过去时：studies改成studied
小题3:他太困太累以至于不能有效的学习。这里用so…that句型：too改成so
小题4:在星期天的早上用介词In
小题5:他刚要学习这时爸爸过来建议他休息一下。词组：have a break休息一下
小题6:他们买了一个非常喜欢的风筝。这句话用了定语从句，先行词是kite，定语从句省略的关系代词，所以定语从句中应该缺少宾语，去掉it
小题7:他们到了郊区，在那里汤姆自己玩放风筝。Enjoy后面接动名词：fly改成flying
小题8:全家人一起野餐，在户外感觉很放松。这两句话是并列关系：but改成and
小题9:星期一的时候，汤姆在教室里面精力充沛很积极。和energetic并列做表语，应该是形容词： actively改成active
小题10:他说这只是因为他度过了一个很好的周末。This is why“那就是为什么”，改成That is because“那就是因为”
考点
据考高分专家说，试题“假定英语课上老师要求同桌之间交换修改作文.....”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
