新托福写作的评分标准比较高，在语言上的考察点也是非常高，所以新托福考试在语言上一定要引起极度重视，很多考生对于托福写作一筹莫展，那么我们怎么完成一篇优秀的文章呢？其中词汇的重要性我们必须重视，包括遣词和造句两个方面。下面小编为大家分析下三大类型的病句。
1、破碎句
所谓破碎句，就是句子不完整，通常是没有谓语（或者说谓语是动词的非谓语形式，如分词），或者是从句单独成句。
破碎句：She singing alone.（无谓语，singing是现在分词）
正确句：She is singing alone.
破碎句：He did not come. Because he was sick. （从句单独成句）
正确句：He did not come because he was sick.
2、接连句
所谓接连据，就是两个句子直接连在一起，既未使用连词，也未使用正确的标点符号。
接连句：Professionals such as lawyers or accountants usually work longer hours than factory workers they have greater freedom in planning their time.
正确句一：Professionals such as lawyers or accountants usually work longer hours than factory workers. However, they have greater freedom in planning their time.
正确句二：Professionals such as lawyers or accountants usually work longer hours than factory workers; however, they have greater freedom in planning their time.
3、句子连接不正确
所谓句子连接不正确，就是两个独立的句子之间以逗号连接，这是不合英语语法的。正确的做法是以连词、分号、冒号、句号等连接两个句子。
不正确句：Breaking chalk into two pieces is a physical change, there is no change in the composition of the chalk.
正确句：Breaking chalk into two pieces is a physical change, so there is no change in the composition of the chalk.
