英语语法改错网站是ComposAI 。但是app的更准确：Grammary。

原理：

原句常见的主系表结构的简单句。主语oneofthem，系动词为be的变化形式is，后面的成分充当表语。翻译：他们其中一个缺钱。

其实从语法角度讲，改了之后句子本身也是成立的，但是从意思上看，和原来要表达的东西差别很大了。

重点语法：

英语最基本的句型结构是简单句，共有五种基本类型。它们以谓语动词是否是实义动词，实义动词又是否可区分为及物动词与不及物动词，而进一步划分为五个基本类型。这五种类型分别是：

①以系动词充当主要动词的主系表结构。

②以不及物动词为谓语动词的主谓结构。以及物动词为谓语动词。

③主谓宾结构。

④主谓双宾语结构。

⑤“主谓宾+宾补结构”。
