这“十大句式”具有一定的普遍性。事实上，“十大句式”在阅读论文和论文写作中出现的频率相当高，也是广大科研人员非常熟悉的句式。一旦科研人员熟练地掌握了它们的用法，就能根据内容表达的需要，随时派上用场。
对科研人员来讲，用英文进行科技论文的写作只是一种表达的方式，英文只是一种表达的工具，平时较少关注如何运用多种句式的意识，因此多数科研人员以自己头脑中拼凑的中式英语取而代之，往往想不到运用这些句式。
那些感觉句子写起来挥洒自如的科研人员，其中或多或少地在使用十大句式，在一定程度上说明他们头脑中已经培养起句式写作潜意识。
这“十大句式”中除了否定句、倒装句、插入语一般可以写成简单句以外，其它6到7句都属于复合句，占到总数的三分之二以上。
