What conclusion can be drawn, for example, from Allen's discovery that Puritan clergy who had come to the colonies from East Anglia were one-third to one-half as likely to return to England by 1660 as were Puritan ministers from western and northern England?We are not told in what way, if at all, this discovery illuminates historical understanding.
if at all. 是个缩略了的句子. 是指: 1) 可有可无的东西, 2) 可做可不做的事, 3) 或可能成,也可能成不了的事.
翻译成汉语时可在这个结构上变化: 就算是有(要,行,做...), 也只是(...)而已.
eg.1.(去菜场买菜) We are out of vegetables so we need to buy vegetables. But we still have lots of frozen meat in the refrigerator, so we will just get a few lbs., if at all. 蔬菜是要买了.可冰箱里肉还有很多,要买,也稍为买几磅就行了. (这个 "all" 还意犹未尽, 如到时再说,看价格好又新鲜等等因素,尽包括在"all"里头了. "If (we are going to get any meat) at all.")
eg.2.(去北京玩) We only have two days in Beijing, so we must see the Great Wall (which takes one day) and the Forbidden City (which takes another). As for shopping, we only have time for Wangfujing next to our hotel, if at all. 就算有时间购物,也只能在附近的王府井转一转了. "If (we have time to shop) at all." [ Even if we have time left for shopping after all the places we want to see first.]
