我今天需要培训英语的英文

这句话是典型的中文常见表达，副词短语置于主谓宾结构之前，翻译为应英文时应该倒置，成为英文的正常语序。“从今天开始”，其实指的是“from now on”，即从现在开始。而动词“学习”其实意味的“努力学好”（learn well），或者“提高”（improve）的含义。建议的译法：I've decided to learn English well from now on.I will improve my English from now on.

I will study English from today on。

We will have an English lesson today.

Tody we are going to have an English class
