我写了一个英语句子,请大家看看有没有语法错误

这句话没有语法错误,但表达比较别扭,可适当改进：
It is more likely for government rather than companies to decrease...

it is more likely that government would ease the immoral behavior in some filed of scientific research then companies.

it is of more probability/likelihood for government than companies to decrease 有点问题 两种该法
一：it is of more probability/likelihood for government than that of companies....
而：it is of more probability/likelihood for government Instead of companies ...

错了，首字幕应该大写，而且结尾是.
