题目分析:
略
选项分析:
A选项:Correct. 本选项在语法上和逻辑上均是正确的。连词but身后省略了主语sunspots。
B选项:that never have been sighted是限定性定语从句,其就近修饰名词dark spots,即,have been sighted的主语是dark spots,但是,在逻辑上,从来不在太阳的极点和赤道上被看见的(have never been sighted on the Sun’s poles or equator)应该是太阳黑子(sunspots)而不是黑子(dark spots)。
C选项:本选项措辞有误。appear是“出现”的意思。在逻辑上,是在地球上看Sunspots时,它们长成黑点(dark spots)的样子,即,可视为黑子(are visible as dark spots)。如果用appear as dark spots,则好像是在说,Sunspots自己就出现为黑点的模样。这显然是不合逻辑的,在太阳上看,Sunspots可不是黑点,而是各种太阳的运动。
D选项:本选项错误同(C)。
E选项:which never have been sighted是非限定性定语从句,其应该就近修饰复数名词dark spots,逻辑主语错误同(B)。
appear是“出现”的意思。在逻辑上,是在地球上看Sunspots时,它们长成黑点(dark spots)的样子,即,可视为黑子(are visible as dark spots)。如果用appear as dark spots,则好像是在说,Sunspots自己就出现为黑点的模样。
appear as是物体呈现出的一种状态,vortices of gas associated with strong electromagnetic activity这句话已经解释了sunspots的概念,即便是用appear as,也应该是呈现出vortices的状态,而非dark spots。从句意来说,无法在太阳两极或赤道观察到的应该是sunspots,而非dark spots。排除BCDE

读懂题在判断 赵全判断点
1.although+verbed/verbing不能一棍子打死,og有此例作为正确选项的,没有用“although后必须加完整clause”作为判断依据,所以应该还是看逻辑主语是否符合逻辑最为清晰。
问题的关键是have never been sighted on the Sun's poles or equator 是修饰sunspots还是dark spots(X)的
如果像(B) (E) 这么构句,主句就变成了
(B) Sunspots are visible as dark spots [定语从句修饰dark spots]
(E) Sunspots appear as dark spots [定语,定语从句]
都很疯批,句子的中心全部转移到描述dark spots了,那为什么主句主语还要是Sunspots?
那么再看(C)(D)(al)though的用法,正确的用法只应该是
(C) ... as dark spots, although (sunspots were) never sighted at
(D) ... the Sun, although have never been sighted at
although 后面不一定要跟完整句,是可以省略主语主语+动词的,但是补上之后,一定要合理
apear 也有 seem; give the impression of being. 的意思, 这样c选项看上去也可以?
Although typically introduces a subordinate clause, which has a subject and a verb,but here there is no subject and "sighted' is not a complete verb.

读A的之后but前后句子成分完整,保留———B:后面再接上没画线的句子根本读不通,排———C:appear as不分开,排———D:having been done排———E:which就近修饰,但是与被修饰的名词隔太远———选A

appear as = show up as , 只是like 不是 appear as CDE不要了,which E中也不对
AB考的是句意,不是darkspots没被看见是sunspots没被看到
选B就很酷 on the surface of the Sun the Sun's poles or equator.
appear as 表示XX物体呈现出来一种样子,可是,前半句已经解释了,sunspots是一种漩涡,所以只能是“看起来是”一种黑斑,而不能是呈现出黑斑的样子(应该呈现为漩涡的样子)
although 表达的意思是让步,这里的意思是but转折,连接词使用错误。
C与D错在appear的使用上,although的使用是不是均正确?C为过去分词表被动,D为完成时态表示动作发生在过去

although后不是必须要接clause,比如Although feeling damn hungry, I had to stay to listen to the boss’s sermon.
但是,当although出现在主句之后时,不能省略主谓语。(When ‘although’ is found after the main clause, then it can only be a conjunction and should necessarily start subordinate clauses. It cannot be a modifier. )
比如 I had to stay to listen to the boss’s sermon, although I was feeling damn hungry. 正确
I had to stay to listen to the boss’s sermon, although feeling damn hungry.不正确
就想问这个,特别好:)
为啥啊,这个是哪里的讲解啊?大神求教

OG的解释是“although”后面通常接有主语和谓语的从句,本题C中的although后面既没有主语,谓语也不对。
