副词的位置 [学术英语写作]

英语写作中，副词在的位置用法比较复杂，取决于写作形式（正式与非正式）、副词的长度、意义和在句子中的作用各种因素。

在学术英语写作中，副词所修饰的对象主要是形容词和动词或者整个句子，它与被修饰的对象之间的位置关系主要有以下几种：

• 当被修饰的主要动词为一个单词时，将副词放在访动词前。

Wheelchair tie-down systems typically use for four adjustable-length straps to secure the front and rear of the wheelchair…

• 但动词“be”除外，副词常位于”be”动词后面。

It was particularly clear that the solutions…

• 副词一般位于第一个助动词后。

… It could also have been applied to other aspects of the motor.

• 但是一些表示完整性和方式性的副词位于所有助动词后。

The waves could be completely used without any loss as exhaust.

The system could be successfully used to interrogate…

• 由短语或从句构成的副词，一般放在句首或者句末。

Early fractions containing more polar compounds were subsequently analysed using a weaker isocratic eluent.

After this, early fractions containing more polar compounds were analysed using a weaker isocratic eluent.

• 连接副词，比如：however, therefore, by contrast等，放在句首，以表明与前一个句子之间的关系，这样的用法会使得两个句子之间的关系非常清晰明了。

Nevertheless, this initial work may prove to have an impact in eventually shaping the admission policies of Canadian medical schools.

必须指出，这些规则并不是那么严格（语法永远都不是很严谨），只是学术英语写作中较为普遍的用法。
