关于论文写作技巧
今天介绍一下连字符“-”的用法
动名词组合用作形容词,两词之间要加连字符
例:
“The drug induced side effects”
如果作为一个单独的句子,“The drug induced side effects. These included headache, nausea, ...”此时,“drug”是作为主语,而“induced”是一个动词过去式作谓语,这句话表示“这种药物会引起副作用”。
如果作为一个句子中的一部分,“The drug-induced side effects ... of aspirin include GI distress.”此时,“drug-induced”用连字符连接,在句子中充当形容词,修饰“side effects”,表示“由药物引起的副作用”
这一原则多用在动词的-ed, -ing,以及-ent形式中(当它们被用作形容词时)。
例:
receptor-mediated; exercise-induced asthma; site-directed mutagenesis; FDA-approved drug
drug-metabolizing enzyme; ligand-binding domain; rate-limiting step
concentration-dependent effects; ligand-independent transactivation; RNA-dependent DNA synthesis
形容词动词结合作为形容词,两词之间要加连字符
例:
“blue-labeled tubes”是指试管上贴了蓝色的标签
如果有两个术语修饰同一个词,这两个术语需要加连字符
例:
the Ca2+- and phospholipid-dependent enzyme PKC
The epinephrine- and isoproterenol-induced responses were both blocked by propranolol with similar potency.
The drug-sensitive and -insensitive cells were compared for… two words after the hyphens instead of before
副词与动词结合作为形容词,两词之间不加连字符
以“y”或“ly”结尾的词通常是副词,应为它们总是用来修饰动词或形容词的,所以不用加连字符
例:
a newly identified enzyme
A highly regarded expert in the field
A very limited interaction
