整体感觉作为初中生来说稿子很不错.
mother-love 应该是mother's love,如果是规范用法的话,
用"-"连起来的两个词用作定语,比如：
six-kingdom alliance 六国的联盟
但有以下几点建议：
1 they were surprised to find that a baby in her arms was still alive
可以改成高级一点的：
to their surprise,there was a baby still being alive in her arm
2 Besides this story,many other stories also moved us deeply .From these stories,we know more about love.
合并成从句会显得很有水平：
Besides this story,many other stories from which we know more about love also moved us deeply.
3 There is someone who will care you and love you forever,that is your mother.
可以改成强调句,可改可不改,是高中句型
It is your mother who will care you and love you forever.
建议就这些,你写的很不错,保持你的英语才华,再加修炼的话会成为那种被人们敬佩为会地道英语的学生的.
如果可以的话,以下的一些话可以作为参考,插入在合时的位置.
The great love of the mother spread over the nation when the message,though,being very short,was shown on the screen.
These stories makes our heart warm when the terrible disaster struck our country.
