This has contributed to a big increase in extramarital liaisons.
因此婚外情的现象越来越普遍。
This may be one reason why Mr Hollis tends to address his subject formally throughout his book, frequently by his full name, and does not delve—beyond polite speculation—into the various extramarital romances Thomas may have had.
这或许能够从一个方面解释为什么霍利斯在写这本书时自始至终都郑重地论述主题,提到托马斯时常常以他的全名相称,而且并未探究托马斯可能有过的几段婚外恋——只是礼貌地进行了一些推测。
