8. In late 1997, the chambers inside the pyramid of the Pharaoh Menkaure at Giza were closed to visitors for cleaning and repair due to moisture exhaled by tourists, which raised its humidity to such levels so that salt from the stone was crystallizing and fungus was growing on the walls.
 
(A) due to moisture exhaled by tourists, which raised its humidity to such levels so that salt from the stone was crystallizing
 
(B) due to moisture that tourists had exhaled, thereby raising its humidity to such levels that salt from the stone would crystallize
 
(C) because tourists were exhaling moisture, which had raised the humidity within them to levels such that salt from the stone would crystallize
 
(D) because of moisture that was exhaled by tourists raising the humidity within them to levels so high as to make the salt from the stone crystallize
 
(E) because moisture exhaled by tourists had raised the humidity within them to such levels that salt from the stone was crystallizing
OG解释中1.不明白为什么DUE TO会使这个句子语义模糊 2. 解释中C，D选项中的THEM会可能指代TOURISTS，但是为什么E选项中的THEM就不会呢？

103. El Niño, the periodic abnormal warming of the sea surface off Peru, a phenomenon in which changes in the ocean and atmosphere combine allowing the warm water that has accumulated in the western Pacific to flow back to the east.
 
(A) a phenomenon in which changes in the ocean and atmosphere combine allowing the warm water that has accumulated
 
(B) a phenomenon where changes in the ocean and atmosphere are combining to allow the warm water that is accumulating
 
(C) a phenomenon in which ocean and atmosphere changes combine and which allows the warm water that is accumulated
 
(D) is a phenomenon in which changes in the ocean and atmosphere combine to allow the warm water that has accumulated
 
(E) is a phenomenon where ocean and atmosphere changes are combining and allow the warm water accumulating
一开始错认为a phenomenon 是El Niño这个主语的同位语，如果ALLOWING变成ALLOWS，这个A PHENOMENON这段话就可以当同位语修饰了吗？谢谢！

分析下句子结构呀~·
LZ的句子是这样的：El Niño, the periodic abnormal warming of the sea surface off Peru,（两个逗号见插入的同位语可去掉，不影响主要表意和句子结构） a phenomenon in which changes in the ocean and atmosphere combine，allows the warm water that has accumulated in the western Pacific to flow back to the east.（重要成分已加粗）句子主干就变成了El Nino,..., a phenomenon... allows....，这里面就是有“两个主语”了，a phenomenon就多余了呀，不能做同位语的

第二题我没懂你问的是什么。。。

你好，那第一题应该是DUE TO/BECAUSE OF HIGH LEVEL OF HUMIDITY对不对？另外能否再解释一下宾语位置的代词指代？C,D项还是不太懂。。E选项中没有WAS EXHALED BY TOURISTS只是EXHALED BY TOURISTS，谢谢。

第一题 联系句子意思 是因为tourists呼出了moisture moisture提高了湿度 因此才需要关门清理 像 due to, because of后面都加直接原因 所以AB选项的due to+moisture D because of+moisture就变成了由于moisture才需要关门清理 句子意思变模糊了 因为本来想表达的意思是 呼出moisture提高湿度这个原因才整修 你可以再看一下OG的解释

whihin them 这里的them是宾语位置的代词指代 因为E中的tourists在一个介宾结构中 was exhaled by tourists 所以代词指代的时候更倾向于指代介宾结构前面所有的合适的名词 而不是介宾结构里的词 所以宾语位置的代词指代最好保证前面有一个合适的名词 不去指代介宾结构里面的词 类似的一题OG13-81Fossils of the arm of a sloth found in Puerto Rico in 1991, and dated at 34 million years old, made it the earliest known mammal of the Greater Antilles Islands.   这里的it也不指代 a sloth也是因为a sloth在介宾结构的位置中
