今天，要和大家分享的是托福写作必备基础句型，托福写作备考时需要积累一些基础句型，让自己的表达更加恰当，接下来就来看一看这些整理好的内容吧!
一、准确的句子表达
1. 句型分析
英语的句型包括以下几种，简单句、复合句、并列句、并列复合句等。在新托福写作中，一般使用复合句，辅以并列句和并列复合句，当然肯定要有简单句，做到长短句相结合。下面摘抄几个句子给大家认识并分析一下复合句和并列复合句。
a. Even though I usually know what I have to say， I cannot always express myself correctly in English.
这句话是一个复合句，由even though引导的让步状语从句。
b. This challenges me to practice my spoken English， with the result that I can complete the speaking tasks more fluently and quickly.
这句话中是一个复合句。with介词结构中，有一个that引导的同位语从句对result进行解释说明。
c. I think this is less than ideal because any differences in opinion become personal conflicts， and therefore that might jeopardize the employee’s job.
上句话是一个并列复杂句。and 连接了两个句子，是一个并列句;because引导的原因状语从句。
d. Shallow writing is indicative of weak critical-thinking skills， and such writing， which is often described as “sophomoric”， receives low mark.
这句话同样是并列复杂句。由and连接两个句子，成为并列句，再一个which引导的定语从句。
2. 有问题的句子的列举
考生写的句子容易出现三个问题：一是使用破碎句，二是使用接连句，三是句子连接不正确。
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.
