sci论文写作难点怎么办(你知道如何使用)
在科学写作中,下列哪个句子是正确的?
- The mean score among the students was 20. The score among the staff was 10 however.
- This study used a small sample. Our previous study however used a large sample.
- This interview study reveals varied responses from 10 students however small group data cannot be generalized.
- The interview responses from the students however small the group reveal problems with the new policy.
这些句子都可以改进。首先,“however”可以是表示对比的副词,在句中位置较灵活。在句子(1)中,在最后一个词“however”之前添加一个逗号,有助于将对比表达清楚:“The score among the staff was 10 however”。当表示对比的“however”出现在句子中间时,比如句子(2),两边都加上逗号可以更清楚:“Our previous study however used a large sample.”与“In contrast …”或“By contrast …”类似,“however”也可以移到开头,后面跟一个逗号:“However our previous study used a large sample.”
其次,“however”可以是让步副词(承认相反),如“nevertheless”、“still”、“at the same time”或“in spite of that”。在句子(3)中,有两个独立的子句,每个子句可以是一个完整的句子,因此在“however”之前需要一个完整的句号或分号。有些作者在“however”在句首时后面不加逗号,但加了逗号更清楚。在形容词“small-group”之间加一个连字符更好:“However small-group data cannot be generalized.”
第三,“however”可以是程度副词,意思是no matter how,如句子(4)。它也表示让步,但在“however”和形容词“small”之间没有逗号。因为短语“however small the group”是额外的信息,应该放在一对逗号之间:“The interview responses from the students however small the group reveal problems with the new policy.”
