Neither of us realized that night that these carvings and paintings dated back 15,000 years, nor that the headline in the newspaper would be “The find of the century — Children aged 13 and 11 discover cave paintings.” (《高中英语教科书》第三册,人教社,p. 136)
我认为该书 date back 的用法是错误的。ALD 上只有 date back to/date from,《英华大词典》(p. 340) 也只有 date back to/date from,而无 date back 的用法。故本人认为上句中的 dated back 应改为 dated back to,并在 15,000 years 之后加上副词 ago。您认为呢?
不能认为凡在某些权威词书中没有找到的用法便是错误的。实际上,date back to/date from 和 date back 的用法都是正确的,只是搭配关系有所不同。date back to/date from 后接一个过去的具体时间(have existed since a particular time in the past),而 date back 后接一个时间长度(have existed for the length of time mentioned),可以译为“已存在”“追溯到……以前”。请对比:
-
This tradition dates from/back to( = has existed since) medieval times. 这一习俗始于中世纪。
-
This castle dates from the 14th century. 这座城堡建于 14 世纪。
-
Our partnership dates back to 1960. 我们从 1960 年就合伙了。
-
The custom dates from the time when men wore swords. 这项习俗始于人类佩带刀剑的
时代。
-
All that's an old tradition. It dates back several centuries, you know. 这是一种很古老的习俗。你知道吗,它已存在好几个世纪了。
-
There had been an amazing discovery of human remains dating back nearly two million years. (Cambridge International Dictionary of Phrasal Verbs) 人们发现了已存在约二百万年的人类遗迹, 这是很令人惊奇的。
-
It's a tradition that dates back at least a thousand years. (Oxford Phrasal Verbs) 这是一种至少已存在一千年的习俗。
上面的例5、6、7可以证明《高中英语教科书》上的句子是正确的。
[附注]《英语词组大全》(中国科技大学出版社, p. 216) 将 date back 译为“始于”“追溯到”,是不正确的。这应该是 date back to/date from 的译法。
