El Nino, 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 oa:d i choosed the right answer, but i wonder the og explanation concerning E--------- E:'where' can't correctly refer to 'phenomenon' ;‘are combining' is the wrong verb form. why wrong?
首先allow 前的to 变成and使得句意改变,combine是为了allow the warm water blabla...,所以用to表目的更合适,而不是用and表示并列
其次,是water先accumulate之后才flow back的,所以用现在完成时和一般现在时可以清楚地表示出事件的先后顺序。
总之就是要理解句意然后做题
看了LS各位的解释,实在是有话要说:
2L说的in which优于where,这个说法实在是不敢苟同,首先,in which 是介词+关系代词,而where是关系副词,它们不存在谁优的问题,只有在定语从句下,而且被修饰语表示地点情况下,in which才可以和where互换。在这里,a phenomenon 明显不是个地点,所以这里不能用where,而不是优不优的问题。
再有,还是2L说的,在GMAT里尽量不要用现在进行时,这个要记住哦,这个也实在不敢苟同,因为无论是GMAT什么部分,包括逻辑,语法,阅读等等,用到现在进行时的句子数不胜数,而且GMAT不可能认为现在进行时是错误句式。(的确GMAT里规定过,科学现象和客观事实要用一般现在时,但那要看具体情况)。are combining' is the wrong verb form在这里之所以被判定为错误句式,不是因为现在进行时本身错了,而是因为are combining 在时态上根本无法与前面的the periodic abnormal warming of the sea surface off Peru的 periodic abnormal warming对应,所以它错了。
