Answer 1

When I was 10，once my parents were away on business，but   I had to stay at  home alone for a day．I got up early in the morning，thinking about different  activity I 
could do．The first idea was that I could play computer games all through the day without∧blamed by my mother．Minutes later，I said to  me，"Why don't I do something meaningful？"So I planned to cook  the meal for my parents．I tried to recall  how my mother usually did in the kitchen and arrange everything on my own．With a whole day's effort，I finally made it．I felt it very happy when I saw my parents eating the meal cheerful．They couldn't help  say that their son had grown up．
详
1．but改为and；考查连词，分析句意可知此处上下文之间是并列关系，而非转折，故用and．    
2．activity改为activities；考查名词单复数，different意为"不同的"，后面跟名词的复数形式．
3．在blamed前面加being；考查动词的语态，主语I 与动词blame是动宾关系，故在介词without之后加being，构成被动结构．
4．me改为myself；考查反身代词，say to oneself 是固定搭配，意为"心里这样想，在心里说"．
5．the改为a；考查冠词，这里名词meal在文中第一次提到，故用a表示泛指，a meal意为"一顿饭"．
6．how改为what；考查名词性从句，这是一个宾语从句，从句中动词did缺少宾语，故用疑问代词what作从句中的宾语．
7．arrange改为arranged；考查动词的时态，此处的动作发生在过去，要用一般过去时．
8．去掉it；考查代词，分析句意为"我感到非常高兴"，very happy 作felt的表语，it多余，故去掉．
9．cheerful改为cheerfully；考查副词，此处用副词作状语修饰动词eat．
10．say改为saying；考查非谓语动词，couldn't help doing是固定搭配，意为"禁不住做某事"．
