关于新概念第四册中Lesson15的几个问题
1.Two factors weigh heavily against the effectiveness of scientific research in industry.One is the general atmosphere of secrecy in which it is carried out,the other the lack of freedom of the individual research worker.
the other 后为什么不用加s?individual在这里是什么意思?
2.Many firms,for instance,have great difficulty in obtaining technical or scientific books from libraries because they are unwilling to have names entered as having taken out such and such a book,for fear the agents of other firms should be able to trace the kind of research they are likely to be undertaking.
中文翻译是“比如,很多公司向图书馆借阅科技书籍时感到困难,因为它们不愿让人家记下它们公司的名字和借阅的某一本书.”主语补语as having taken out such and such a book似乎不受are unwilling to影响,怎样理解成“因为它们不愿让人家记下它们公司的名字和借阅的某一本书”?
第一个问题“the other 后为什么不用加s?”的s写错了,是is
关于新概念第四册中Lesson15的几个问题
1 因为前面有one.one .the other 是固定用法,不能加s.individual是“个人的”意思.
2 个人理解,as having taken out such and such a book应该是时间状语“当借阅一本又一本这样
的书籍时“
翻译:比如,很多公司在借阅图书馆的图书时有麻烦,他们不愿意在借阅一本一本书籍时被记录下
公司的名字和书籍的名字,(他们)担心其他公司的探子有可能追踪到他们正在进行的研
究.
拙见,供参考.
再问: 谢谢,第一个问题不小心写错了,是“the other 后为什么不用加is?”另外,如果是时间状语,as having taken怎样理解?
再答: one后面有个is,根据句式,应当是承前省略。 例如 on monday,I ate an apple,and tuesday,a pear. 不知理解得对不对......
再问: 受教了,另外如果是时间状语,as having taken怎样理解?
再答: as引导现在分词短语,相当于时间状语从句 when they have taken......
再问: 但是as或when真的可以加完成时吗?而且as...不从属于are willing to,很难理解成“它们不愿让人家记下它们公司的名字和借阅的某一本书”,这个问题好像还是有疑问
再答: as、when+doing结构在英语句子中很常见。 eg You can't imagine what difficulty they had when carrying out the plan. Tom lost his purse as passing the railway station. having done 的语法意义是 “在主句谓语动词之前已经完成某事” 愚见在本句中as having taken.... 应当修饰其前的 are unwilling to have names entered这一谓语。
