请问下面的译文将 as a whole 译为“总的来说”是否正确？它与 on the whole 有无区别？The study of words is the business of LEXICOLOGY but the regularities in their formation are similar in kind to the regularities of grammar and are closely connected to them. Meaning relations as a whole are the business of SEMANTICS, the study of meaning, and this therefore has relevance equally within lexicology and within grammar. (GCE, p. 8)
[原译]研究词汇是词汇学的任务。但是词汇的组成规律与语法的规律在性质上是相似的，并与语法的规律是紧密关联的。总的来说，研究词义的关系是语义学的任务，也就是研究词的意义。因此，这就和词汇学与语法都有了同等的内在联系了。（《当代英语语法》）
上面的译文把 as a whole 与 on the whole 的含义弄混了。
on the whole 意为: “总的说来”(generally)、“基本上”“大体上”。一般用作句子状语:
-
On the whole I am quite satisfied with the experiment. (Chambers) 总的说来我对实验很满意。
-
You have made a few mistakes but on the whole you have done well. (ELD) 你犯了一些错误,但是总的说来你做得很好。
-
On the whole, early American city planning was excellent. (TOEFL) 总的说来,美国早期的城市规划还是很好的。
as a whole 则表示把某事或某几件事当做一个整体来看。既可作状语，也可作定语：
-
We must examine these problems as a whole. (ELD) 我们把这些问题作为一个整体来考察。
-
That was her final judgement on the story as a whole. (London) 这就是她对整个故事的最后判断。
-
As a whole, the relocation seems to have been beneficial. (RCD) 从整体上看,调动似乎是有好处的。
-
Oxygen is one of the most abundant elements in the earth as a whole. 氧是整个地球内最丰富的元素之一。
-
In general, the application—or misapplication—of science and technology in all fields is certain to affect the structure of society as a whole. 一般说来,科学技术在各个领域中
的应用或误用,必定会影响整个社会的结构。
在你所提问的句子里, as a whole 是 meaning relations 的定语, 而不是整个句子的状语。建议把上面的译文改为:
……研究整个意义关系,则是语义学即意义科学的任务。因此,语义学跟词汇学和语法学都是有关系的。
