托福写作中，如果大家能够很好的运用一些句型，也能够给作文的加分。那么在备考中，同学们具体的应该掌握哪些句型呢?
把重点摆在句首或句尾
一般而论，最显眼的位置是在句尾，其次是在句首，中间的位置最平淡，乏善可陈。
例如：
The history of vocabulary is, in many ways, the record of civilization.
把重点放在句尾是种“吊胃口”的方法，读者或听者非得读完或听完整句不可。
在复杂句里，把主句放在从句之后。
除了名词从句和形容词从句之外，因为它们位置较固定。副词从句中有几种从句位置灵活，可以在主句之前出现，也可以跟在主句之后。通常我们就把这样的副词从句提前，重点则放在后头的主句。
(a) I came upon an old classmate when I went to town yesterday.
(b) When I went to town yesterday, I came upon an old classmate.
副词短语更是如此，
(a) Steel is commonly used to make knives, razors and other useful tools because of its durability.
(b) Because of its durability, steel is commonly used to make knives, razors and other useful tools.
把较重要或有分量的词语放在后头
(a) That singer's life was tragic and brief.
(b) That singer's life was brief and tragic.
把句子中一系列的项目作逻辑性的排列。例如：
Tony ate his dinner, watched TV, and then went to bed.
必要时，重复重要的语词或概念。例如：
...the land stretched out without names. Nameless headlands split the surf; nameless lakes reflected the nameless mountains and nameless rivers flowed through nameless valleys and nameless bays.
