求问OG17的几道题 题号707 687 680 能解决的了一道是一道

想了很久还是不太懂，所以渣渣只能上来伸手问了
707.Not trusting themselves to choose wisely among the wide array of investment opportunities on the market, stockbrokers are helping many people who turn to them to buy stocks that could be easily bought directly.
(D) many people are turning to stockbrokers for help to buy stocks that easily could have been
(E) many people are turning to stockbrokers for help in buying stocks that could easily be
OG解释
(D) To buy is not idiomatic in this context—in buying would be correct—and the tense of the verb could have been does not match the tense of the verb earlier in the clause; the point is not that people are turning to stockbrokers for help in buying stocks that at some earlier time could have been bought directly, but rather that the stocks could be bought by the people directly at the very time they are seeking help from the stockbrokers.
(E) Correct. The opening clause correctly modifies many people, and the adverb is correctly placed.个人疑问
我把选项D的解释翻译了一遍，但还是看不太懂他的意思，为什么不能用to,这里不就是要表达向stockbroker寻求帮助来达到目的吗？还有使用了虚拟语气后句意有什么区别？总而言之，解释看不懂啊

687.Sunspots, vortices of gas associated with strong electromagnetic activity, are visible as dark spots on the surface of the Sun but have never been sighted on the Sun’s poles or equator.
(C) appear on the surface of the Sun as dark spots although never sighted at
OG解释
(C) 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.
个人疑问
为什么说这里的sighted不是一个complete verb？although+verb应该怎么样算是正确使用？？

680.Although Alice Walker published a number of essays, poetry collections, and stories during the 1970s, her third novel, The Color Purple, which was published in 1982, brought her the widest acclaim in that it won both the National Book Award as well as the Pulitzer Prize.
(B) published in 1982, bringing her the widest acclaim by winning both the National Book Award and the Pulitzer Prize
(C) published in 1982, brought her the widest acclaim, winning both the National Book Award and the Pulitzer Prize
OG解释
(B) Because this sentence uses only participial phrases in the clause following the initial, dependent clause, the sentence lacks a main verb and is therefore ungrammatical.
(C) C Correct. This version correctly uses the form both x and y and is grammatically correct.

个人疑问
B的翻译到底在说什么我只看懂了缺乏主要动词，前面那句我翻译了我也不懂，求科普一下。

还有为什么选C不能选B，c为什么是用winning而不是won跟前面的brought publlished对称哦。我真的是语法盲轻喷

额外再问个小问题，just like ......和just as....... 有什么区别哦，然后为什么可以用just as ..... so 但不可以用 just like .... so


求大牛们解答跪地感谢！！！！！！

再问个小小问问，据说有人一周刷OG，这到底是怎么做到的，有帖子吗

谢谢。
help in那个用法我是看的曼哈顿idiom那章的解释。可能也是他们总结了og的解释后列出的吧。
althou ...

没关系，大家一起讨论嘛。理论上在有OA prove之前是没办法判断官方的态度的，不过help这种应该还是挺普遍的用法。

不过Although的使用其实并没有preference，下面是Ron的解释，你可以看看，不过不需要记就是了。我其实也没记。。
quote Ron

if "(al)though xxxx" PRECEDES the sentence, then "xxxx" can be either a complete sentence or an adjective/modifier.
if "(al)though xxxx" INTERRUPTS the sentence, then "xxxx" should be only a modifier. in this case, "xxxx" should NOT be a complete sentence.
if "although xxxx" FOLLOWS the sentence, then "xxxx" should be a complete sentence. in this case, "xxxx" should not be a modifier/adjective.

although我写错了，是typically，不是only，已经改了

help in doing 和 help to do 都是可以的，跟noun 和 verb 无关，没有名词就一定要用Help in doing 的说法，这里OG的解释明显是从OA出发的，OA用了这样所以不是这样就是错的。

Although绝不是只能加从句的，实际上(Al)though的搭配比较复杂，不过SC里基本不会考到这么specific的语法点，现在的难题大多是从句意出发的。

这里是主句缺少Verb，并不是缺少从句。

1.这里不能用help to是因为这个help是名词，名词的用法是help in
2.OG解释的意思是although一般加从句，这里although后面既没有主语也没有动词，所以不对
3.前面那半句的意思：因为这句话只用了分词跟在主句后面（其实应该用从句，也就是说这句话没动词）
个人见解，欢迎指正和讨论。

to buy没什么太大问题，OE这里比较牵强。 后面写的还是挺清楚的，句意不是说这些人去找stockbrokers 去买一些之前可以自己买的股票（could have been 就是指已经买好了的），而是说可以自己买的股票（could be 一般属性）

如果这里sighted是verb，那主语是什么啊。这里though sighted 是past particle, 修饰Dark spots。这里用法是有问题，但是重点不在这里啊，前面就错了。

就是说B没有动词，因为B没有动词所以不能选

Just as so是固定搭配， Just Like = Like， Like  so不是固定搭配。没有能不能用，只是表达的意思不同。

建议先多做做题，上国外论坛查instrutor的解释。多研究把句子看懂
