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)。
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.
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。

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。
想问一下句子成分。
AB选项:Sunspots are visible as dark spots. 是应该理解为[主谓补+状语]的结构,as dark spots是修饰are visible的状语?还是应该理解为[主谓补结构],visible as dark spots整体都是are的补语?
DE选项:Sunspots appear as dark spots. 这个应该理解为[主谓补结构]? appear as是所谓“系动词”吗?
第一种理解是对的哟。
DE选项的那个理解也是对的。

補充C選項
OG解答提到but省略主語,但although省略是有問題的。
句子如果是符合省略要求,還原回來為Sunspots appear on the surface of the Sun as dark spots although [Sunspots are] never sighted at....
但是在這裡碰到了時態問題,原题想表達have never been sighted, 如果想要的话就必须把have been寫出來,省略原則之所以可以省略be,是因為be一般不重要,而這裡顯然不是這種情況。
这里如果要把have been写出来,那么就必须也补全主语,省略的话是主语谓语动词同进同出的,不会出现只省略主语或者只省略谓语动词的情况。这里sighted是过去分词。
"but" is a coordinating conjunction. it's in the same category as "and" and "yet".
"even though" MUST be followed by a clause.
"although", however, can be followed by an adjective or adjective phrase: james, although bigger than many of the other players, is one of the fastest men on the team.
although从句省略主谓,只能省略be一类的词;have been sighted这类词不能被省略
E中which跳跃修饰dark spots;没有转折词,完全改变原句意思
大神这又是哪里的讲解??

错选了C。。。C后面的although缺了was,应该although was never sighted at。。。
C选项although never sighted at ..是否可以看做dark spots的分词定语?
不可以。分词短语作定语,肯定是后置定语,并且也不会出现连词although。
