我的GWD答案是选A的，然后我选了D，但是看到之前的讨论有说选A又有选D的，然后我就纠结了

所以麻烦NN或者斑竹大人能不能出来给个明确的解释？

PS: 出现until是否一定要用完成时？如果不是，什么时候该用，什么时候不该用？

我觉得还是选A好，D整体语句结构比较差。

A. Until recently, the Inuit people led a nomadic existence, sheltering
ANSWER: The list starts after "sheltering". "In igloos" is parallel to "in structures".

B. During recent times, the Inuit people lead a nomadic existence, sheltering
PROBLEM: You can't say "during recent times." During has to be an isolated time frame (During the next five years, during the war, etc.). Also, it would set up present perfect tense, not the present tense.

C. In the times that are recent, the Inuit people led a nomadic existence, sheltered
PROBLEM: "In the times that are recent" is ridiculous, and the past tense wouldn't make sense (but little here does).

D. Up until recently, the Inuit people, leading a nomadic existence, have sheltered
PROBLEM: The "up" is unnecessary. The present perfect tense starts in the past and continues into the present. But the use of "until recently" implies that this has stopped, so the present perfect doesn't work.

E. Until recent time, leading a nomadic existence, the Inuit people were sheltered
PROBLEM: "Until recent time" is gibberish. "leading a nomadic existence" isn't modifying the Inuits anymore.

D选项改变句子的逻辑意思了，原题强调的是inuit过的是一种。。。的生活，D选项更侧重他们shelter的地方

D完全改变了句子意思，句子重心也变化了。这两点我觉得是SC的错误源泉！

最后一楼是RON的解释，可以参考一下哈~

医生吃鱼

RON大神说过：时态选择的核心是句意。
根据该题中的“recently”表示的是”过去的某一刻“（虽然“这一刻”离现在很近），推测句意是：Inuit人现在不过游牧生活了，为了表达“过去做而现在不做”的句意，选择一般过去时，排除BD选项。

以下附上RON大神的对排除D选项解释的原文：
• "Up" is redundant, since "until" already carries this meaning.

• The sentence implies that the Inuit are no longer nomads.
If they were still nomads, the sentence wouldn't say "until recently"; it would say "until now" (or some equivalent). Remember that "recently", albeit not too long ago, is still a time in the past.
So, you need the past tense. In that choice, you'd want "sheltered". Not "have sheltered" (which implies "up to the present").
