一篇自己写的英语作文

My English was poor,but I didn't give it up.（最好说but I didn't give up. give up 是固定词组，放弃的意思）I tried my best to learn English well,（句号，后面大写）for example,I always read English book every moring.（去掉always，显得累赘）Last week,I won the first prize in（加the） English competition.What an unexpect success it is! As a saying goes（as the saying goes,后面标点应该是，又不是语文……）:"Nothing is impossible for a willing heart."I think I will do much better in the future.

语法除一处外基本正确，只是修辞方面需要改进，分述如下：
一、语法：As a saying goes 中的as你是作为“正如”之意使用的，但是此意在英语中是作为关系代词使用的，必须在句子中作成分，如：
As is well known 众所周知，as 作被动语态的主语；
As it is 照现在的样子，as 作表语；
as I think. 正如我所想的，as 作 think 的宾语。
此处的主语是 a saying， goes 是不及物动词，所以as不可能是宾语。当然，as 也可以用作介词，相当于汉语的“如”，但只能用名词作其宾语，而不能用 a saying goes 一类的句子。
有两种修改办法：
1. A saying goes (去掉 as)；
2. As a saying says (把 go 改为及物动词 say，as 用作 say 的宾语)
二、修辞建议
1. My English was poor, but I didn't give it up.
改为 My E
