their可以指代patterns或currents，切忌谓语太靠后导致头重脚轻

1. 这是个强调句：it is only....that....，所以把这个句型去掉之后，根据 in the last half century..知道要用现在完成时。 2.that 后面主语是picture，要用单数。做什么题都要记得检查动词的单复数。 3.picture of the patterns of ocean currents and their causes，their指代不明，而且也没有A中简洁， the patterns and causes of ocean currents 4.B的主语太长了，头重脚轻。 5.a reasonably clear picture has emerged of the patterns and causes of ocean currents属于倒装，把修饰picture的定语of the patterns and causes of ocean currents后置了，迷惑性较大，正常语序应该是：a reasonably clear picture of the patterns and causes of ocean currents has emerged。如果考题这么写，相信很多人都不会错。 .

英语里很忌讳头重脚轻，且此处单复数错误，picture应该用单数，thier的指代也不清

主语谓语不一致！！！ a reasonably clear picture of the patterns of ocean currents and causes of ocean currents has emerged 但是可以把has emerged 提前 a reasonably clear picture has emerged of the patterns of ocean currents and causes of ocean currents

a picture of A and B 应该加has，B主谓不一致

主谓不一致 a picture是主语 后面不能用have 应该为has 其次 their指代不清

their 指代不清 pattern与causes平行

their指代不明 have数格错误，应对应a reasonably clear picture用has 平行也有歧义

has
