托福寫作中，如果大家能夠很好的運(yùn)用一些句型，也能夠給作文的加分。那么在備考中，同學(xué)們具體的應(yīng)該掌握哪些句型呢?
把重點(diǎn)擺在句首或句尾
一般而論，最顯眼的位置是在句尾，其次是在句首，中間的位置最平淡，乏善可陳。
例如：
The history of vocabulary is, in many ways, the record of civilization.
把重點(diǎn)放在句尾是種“吊胃口”的方法，讀者或聽者非得讀完或聽完整句不可。
在復(fù)雜句里，把主句放在從句之后。
除了名詞從句和形容詞從句之外，因?yàn)樗鼈兾恢幂^固定。副詞從句中有幾種從句位置靈活，可以在主句之前出現(xiàn)，也可以跟在主句之后。通常我們就把這樣的副詞從句提前，重點(diǎn)則放在后頭的主句。
(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.
副詞短語更是如此，
(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.
把較重要或有分量的詞語放在后頭
(a) That singer's life was tragic and brief.
(b) That singer's life was brief and tragic.
把句子中一系列的項(xiàng)目作邏輯性的排列。例如：
Tony ate his dinner, watched TV, and then went to bed.
必要時(shí)，重復(fù)重要的語詞或概念。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.

4. 考慮到……：Considering/Regarding/In view of,….
例句：
In the view of the fact, this approach is inadvisable.
考慮到這個(gè)事實(shí)，這個(gè)方法是不可取的。
5. 為了……：for the sake of/for purposes of/in order to achieve sth, …
例句：
They seem to have doing nothing but reading, acquiring more knowledge and really essentially just learning for the sake of learning.(他們好像除了讀書，掌握更多知識、為了學(xué)習(xí)而學(xué)習(xí)之外，什么也不做。)
6. 很容易理解/證明……：It can be easily understood/proved that….
