He was born in September 7th 1930
具体到某天用 on
When he was at school 还是去掉 was
In 1973,He has developed a new kind of rice.
这句话改成有问题
应该有一般过去式 改为 In 1973 He produced
a new kind of rice develop是改进的意思
改进了一种新种米 既然是新的怎么改进呢?
所以改成生产 Then he becomes a famous scientist
应用过去式 且去掉scientist 比较好
Then he became famous
many countries grow more rice than before
这句话 用grow 似乎不妥 改为produce更好
than before 可以省略
其他都可以了

he大写 He worked very hard. When he was at school去掉.grow大概不好。。。改have grown吧。。。
其他没什么了
