复杂句中时态问题

The research found that people who watched a movie in 3D had improved cognitive skills compared to those who watched it in 2D.前三处谓语时态对吗?可以换用其他时态表达同样意思吗?过去完成时是相对哪个过去动作?第二个谓语动词应该先于第三个,但从时态上看第三个先于第二个啊?

The research found that people who watched a movie in 3D had improved cognitive skills compared to those who watched it in 2D.

【翻译】研究发现,观看3D电影者较之观看2D电影者,更加提高了他们的认知能力。

句子含义是:3D电影的效果能够提高人的认识水平。

关于这个句子涉及3个动词时态问题:

1. The research found:“研究发现”,显然指过去“发现”。

2. that people (who watched a movie in 3D) had improved cognitive skills:宾语从句that people had improved cognitive skills中,使用过去完成时had improved,说明早于found,合乎情理。也就是说“提高认知能力”在先,“发现”在后。

3. who watched a movie in 3D who watched it in 2D:两个定语从句在时态方面是一个层次,是对过去事实的客观陈述。因此,过去完成时had improved 与定语从句watched 没有时间比较关系、而且也不强调时间比较关系!它只强调跟主句found存在时间的先后关系。

如果把found 改为一般现在时,那么:

The research finds that people who watch a movie in 3D have improved cognitive skills compared to those who watch it in 2D.
