托福写作转折词的用法
1. 类似于“很多时候there be句型是没有必要的”，考虑是否but可以直接去掉?
试比较
She used to be indifferent to the outside world, but an interloper changed her.
Her indifference to the outside world was changed by an interloper.
2. 可否把but后面的句子改为短小的插入语等成分来体现转折?
试比较
Driven by an interest in words, Claire kept trying poetry, novelsand literature analyses, but she hardly succeeded in any of these endeavors at the very beginning.
Driven by an interest in words, Claire kept trying poetry, novels and literature analyses—all with little initial success.
3. 可否把but 后面部分改为更紧凑的从句?
试比较
It was meant to be a brief parting, but it turned into a long, lingering one.
What was meant to be a brief parting turned into a long, lingering one.
第二句读起来更加集中、紧凑，并且去掉了"It was, but it…”等鸡肋部分。
4. 积累多一些可能的but替换，比如：however/nonetheless/ nevertheless/ yet/ whereas/ while等，常常也能带来新思路。
试比较
Once arriving home, she starts to review all the notes, not necessarily because the teacher requires her to do so,but because she encourages herself to study hard.
Once arriving home,she starts to review all the notes, as much from the requirement of the teacher,as from herself-encouragement.
对于but这一最为常见的转折，我们可以从“是否可以直接去掉?是否可以改为插入语等句子成分?是否可以改为更为紧凑的从句?是否有其他替换表达?”这个方面进行思考。
但应该指出，应该建立在“自己有把握判断原句与改进后句子的风格与质量”的基础上进行。有时候，不一定改的就比原句更好，短的不一定就更简洁。
