42、Scientists have recently discovered what could be the largest and oldest living organism on Earth, a giant fungus that is an interwoven ?ligree of mushrooms and rootlike tentacles spawned by a single fertilized spore some 10,000 years ago and extending for more than 30 acres in the soil of a Michigan forest.
(A) extending
(B) extends
(C) extended
(D) it extended
(E) is extending
为什么选A啊，为什么不选C呢？
43. Laos has a land area about the same as Great Britain but only four million in population, where many are members of hill tribes ensconced in the virtually

(B) of about the same size as Great Britain is, but in Laos there is a population of only four million, and many
(C) that is about the same size as Great Britain’s land area, but in Laos with a population of only four million people, many of them
(D) comparable to the size of Great Britain, but only four million in population, and many
(E) comparable to that of Great Britain but a population of only four million people, many of whom
答案选E。我的疑问是C项OG里说them指代不清，我想不明白前面只有four million people 是复数，其他都是单数，为什么还说它指代不清？
D OG上说and的使用不恰当的加强了后句，我理解的是如果原文中没有and，选项中也最好别加上and，是这样么？
50. According to some analysts, the gains in the stock market re?ect growing con?dence that the economy will avoid the recession that many had feared earlier in

(D) in the economy to avoid the recession many were fearing earlier in the year, and rather to come
(E) that the economy will avoid the recession that was feared earlier this year by many, with it instead coming
答案是A，我选的是D，我知道了recession后面少了个that, OG上说rather to 使句子不完整。那个instead come 的主语是the economy是吧？

73. Combining enormous physical strength with higher intelligence, the Neanderthals appear as equipped for facing any obstacle the environment could put in their path, but their relatively sudden disappearance during the Paleolithic era indicates that an inability to adapt to some environmental change led to their extinction.
(A) appear as equipped for facing any obstacle the environment could put in their path,
(B) appear to have been equipped to face any obstacle the environment could put in their path,
(C) appear as equipped to face any obstacle the environment could put in their paths,
(D) appeared as equipped to face any obstacle the environment could put in their paths,
(E) appeared to have been equipped for facing any obstacle the environment could put in their path,
我的疑问是：1、为什么要用have been equipped即一般现在时，虽然两个含有appear to do 的选项都是一般现在时，但是我不知道为什么要用这个时态
2、为什么path会从复数改成单数？
