Q17
                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 times, leading a nomadic existence, the Inuit people were sheltered.

the answer is D,I think A is also reasonable,what's the meaning of 'Up until '?

I think A is a better choice

A 错

 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.

until要表示延续至今的意思用过去式led不正确，应该使用一般现在时

－－－－－－－－－－－－－－－－－－－－－－－－

D符合意思

up until recently，+完成时

until recently 可以用过去时，

until recently Phil Sayer was one of the biggest telecoms customers in the UK.
Until recently, religion and spirituality were deemed as 'cultural, a product of social conditioning,

也可以用现在完成时：I have a baby hedgie, until recently I have been using recycled paper bedding from the store

Up until recently也可以用过去时：Up until recently, New England was characterized by ethnic diversity but significant racial.

有没有其他更好的解释？

Up until
recently, the Inuit people, leading a nomadic
existence, have sheltered in igloos, the
ice-block domes that are peculiar to north-central Canada,
and in structures made of stones, bones, driftwood, and skins.

Sheltering in
igloos, the ice-block domes that are peculiar to north-central Canada,
and in structures made of stones, bones, driftwood, and skins, the Inuit people
led a nomadic existence until recently.

别争了，这题答案是A，我在GOOGLE上搜索到了New York Times和A类似的原文如下：

An Asiatic people, the Inuits arrived in Canada during the last Ice Age, but some time after the Indians. Until quite recently, they led a nomadic existence, sheltering in igloos, the ice-block domes that are peculiar to northern-central Canada, and structures made of stones, bones, driftwood, sods and skins.

另外，麻烦楼主MM帮我看看这道题：

哟，香香茶，这道争议题的答案也被你找到啦。厉害啊。

这道题目我选A因为我觉得原来句子的重心是强调Inuits过着一种游牧民族的状态，后面的现在分词做伴随状语。如果选D的话，改变了原句的重心。

象这种题目如果两个句子逻辑意思都可以成立，而且没什么错误的话，一般还是选A的好，因为ETS一直强调轻易不要改变原句的意思

这道题目时态应该不是考点。

我之前没有去找的，因为我也认为只要原句的逻辑意思清晰，没有什么错误的话，倾向于原句的选择。但后来看到大家的讨论，就尝试找出来证明这一点。结果很幸运的找到了。

发现很多改错的句子都来源于纽约时报。早知道的话，以前我就该每天读的，这样SC的感觉应该强很多了，哈哈~
