Navigators have known for thousands of years that the ocean has variable currents, but it is only in the last half century that a reasonably clear picture has emerged of the patterns and causes of ocean currents.

题目分析:
本题主要需要看出划线部分是一个倒装句,它的正确语序是a reasonably clear picture of the patterns and causes of ocean currents has emerged,换句话说,它将谓语动词has emerged 倒装在了主语的定语之前,这是为了躲避主语过长的现象。当然,倒装与否并不影响我们判断对错,倒装仅是为了修辞的需要。
本题划线部分的意思是:一个关于海洋洋流的模式和原因的一个相对来说比较清晰的图画已经出现了。
选项分析:
A选项:Correct. 本选项在语法和逻辑上均是正确的。
B选项:主谓不一致,主语的核心词是单数名词 picture,而谓语动词是复数动词have emerged,需要将have改为has。
C选项:首先,emerged应该用现在完成时,而不应该用过去时,表示到现在为止出现;其次,本选项的定语部分of ocean currents, their patterns and the causes of them的核心词有误。该定语的核心词为ocean currents。在逻辑上,这幅清晰的图画应该是洋流的模式和起因的图画,而不是洋流本身的图画(这里的图画是引申意义,大概相当于是“认知”的意思)。
D选项:初中学过一个基本的语法点,即,只有there be句型,没有there have或者there do的句型。
E选项:本选项错误同(D)。
in the last half century 最近的这半个世纪,用现在完成时!不同于in last century
只有there be句型,没有there have或者there do的句型
patterns and causes固定用法,故只有A正确
另外B主谓不一致:a reasonably clear picture (of the patterns of ocean currents and their causes) have emerged. 错误,”have“应该改成“has”
A选项是倒装,把of the patterns and causes放在了谓语之后

in the last century---用完成时, in last century---用过去时;A是 倒装句
简答题!emerged应该用现在完成时,而不应该用过去时,表示到现在为止出现;只有there be句型,没有there have或者there do的句型
谓语啊谓语,这么明白着呢
C错误在于picture内容是ocean current的pattern和cause而不是ocean current、pattern、cause三者一起,三者性质不同,不能并列。
B的their还可能指代不清(patterns/currents)

picture是关于pattern和cause的,pattern和cause是ocean current的。判断好逻辑关系
初中学过一个基本的语法点,即,只有there be句型,没有there have或者there do的句型。
emerged应该用现在完成时,而不应该用过去时,表示到现在为止出现
clear picture of the patterns and causes of ocean currents "has emerged"
B 平行錯誤 their通常不指代所有格
倒装
看清楚成分:本题主要需要看出划线部分是一个倒装句,它的正确语序是a reasonably clear picture of the patterns and causes of ocean currents has emerged,换句话说,它将谓语动词has emerged 倒装在了主语的定语之前,这是为了躲避主语过长的现象。当然,倒装与否并不影响我们判断对错,倒装仅是为了修辞的需要。
只有there be句型,没有there have或者there do的句型。
我想选B的同学并不是像解析说的那样没注意到主谓一致吧………………很明显把picture和causes当成并行主语了啊,可是解析没有回答为什么不能这么看
赞同!做题的时候看出来是倒装了,但是有些困惑为何picture和causes不可平行
patterns and causes或者patterns,causes and consequences,固定用法

倒装句: a reasonably clear picture of the patterns and causes of ocean currents has emerged
B. 主谓不一致,主语的核心词是单数名词 picture
【错因:没看出是倒装;漏看主谓一致;句意拎不清】
只有there be句型,没有there have或者there do的句型。
B选项:主谓不一致,主语的核心词是单数名词 picture,而谓语动词是复数动词have emerged,需要将have改为has。
