请大家把错误的理由写出来下，因为我水平不是很好呀谢谢了

你的英语底子还蛮好的,但有个别地方我觉得还值得商榷一下.
1.我不知道这篇文章用在什么地方,但是我觉得第一句话完全可以不要.
2.Maybe you will say heart or something else,but the correct answer is shoulder.这里最好这样写Maybe your answer is the heart or something else,but the correct answer,in my eyes,is the shoulder.
3.A wide shoulder which your friends or relatives can cry on .
这里并不是一句完整的话.which引导了一个修饰肩膀的定语从句.用强调句你觉得呢?It is a wide shoulder that your friends or relatives can cry on .
4.David’s mother,a kind housewife,one day,she asked her son what the most important body part was in his mind.这里的she使得句子无端多了一个主语,所以不要she才是正确的.然后把one day放在her son后面.
5.Her son said heart at once,she smiled and said nothing.最好把said换成answered\replied,然后在she之前加一个连接词and 或 then.
6.Suddenly she asked her son the special question,David was shocked,and confused.He didn’t know why his mother asked this question again and again.He summoned the courage to ask her mother and knew the answer… 这里的表述有点混乱.你再多读几遍就会明白.
7.The most important part is the shoulder,and sometimes everyone needs a shoulder to cry .用一般现在时就可以了
8.his mother hoped her son would have enough love and shoulders when he needed… 足够的肩膀?hoped 后面不能省that
9.sympathetic是形容词,后面得接点什么
