Q21 Until recently, the Inuit people led a nomadic existence, sheltering in igloos, the ice-block domes that are peculiar to north-central Canada, and in structures made of stones, bones, driftwood, and skins. A. Until recently, the Inuit people led a nomadic existence, sheltering B. During recent times, the Inuit people lead a nomadic existence, sheltering. C. In the times that are recent, the Inuit people led a nomadic exis- tence, sheltered. D. Up until recently, the Inuit people, leading a nomadic existence, have sheltered. E. Until recent time, leading a nomadic existence, the Inuit people were sheltered. Answer: d mine:a 1)有Up until recently?的用法吗?我在语法大全,＆阅读大全中全找了一遍,都没有这种用法,而且在og10中up to是redundant,类似的,我觉得up until也是有问题的. 2)原文主干是 the Inuit people led a nomadic existence,伴随状态说sheltering.....,而d中改变了句子重心,变成leading分词修饰,而shelter主干. 3)b,c中times是次数,排除 4)e中leading a nomadic existence是dangling modifier.而且Until recent time不如 Until recently idiomatic. 5)a中的唯一问题就是until recently是完成时态标志词,但我觉得也不是说有until recently就一定要用完成时态.所以我选择a 阅读大全中就有until recently用一般过去时态的用法.如下: Until recently most astronomers believed that the space between the galaxies in our universe was a near-perfect vacuum. Until recently, scientists did not know of a close vertebrate analogue to the extreme form of altruism observed in eusocial insects like ants and bees, whereby individuals cooperate, sometimes even sacrificing their own opportunities to survive and reproduce, for the good of others. |
