179. During the early years of European settlement on a continent that was viewed as "wilderness" by the newcomers. Native Americans, intimately knowing the ecology of the land. were a help in the rescuing of many Pilgrims and pioneers from hardship, or even death.
(A)    Native Americans, intimately knowing the ecology of the land, were a help in the rescuing of
(B)    Native Americans knew the ecology and the land intimately and this enabled them to help in the rescue of
(C)    Native Americans, with their intimate knowledge of the ecology of the land, helped to rescue
(D)    having intimate knowledge of the ecology of the land. Native Americans helped the rescue of
(E)    knowing intimately the ecology of the land, Native Americans helped to rescue
B creates an awkward, redundant, fused sentence in which the first clause has to be repeated in the vague this of the second clause; furthermore, the comma required before and in larger compound sentences is omitted.
加逗号？？为什么？？

回去再看一下OG179的解释, 才发现你的问题是因为没有注意到解释中的 furthermore, the comma required before and in larger compound sentences is omitted中的"and"是斜体, 意思是指B答案中的第二个and前面应该加逗号, 因为第二个and后面又是一个完整的句子, 不可以不用逗号与前面的分割开. OK?

noven-wang

可是and不是可以连接句子的吗？为什么还要加逗号？

fdkbaby

正是因为连接句子，所以才加逗号啊。两个简单句用连词连接构成复合句（compound sentence－a sentence that has two or more main parts）

如果连接谓语、宾语之类的简单句中的某个成分则不用逗号了。

哦！！我好像一直都犯了一个错误，以为只要有and 连接，句子与句子之间就不用逗号了。天，这么多年都没发现呢。真是谢谢两位啦！！这么说来，如果我说，I am a girl, and he is a boy.要这样表达才对，是吗？？

rabbitbug

Correct!

Snazzy

hold on a second, there is an exception:
'and' can be used to express results and explanation:
Water the seeds and they will germinate. (from dictionary)

noven-wang

哎呀，那这样是不是说，可以要可以不要啊？怎么判断？

noven-wang

我又发现了一道关于and是否要加逗号的题目了，请大家指教。
259. Five fledgling sea eagles left their nests in western Scotland this summer, bringing to 34 the number of wild birds successfully raised since transplants from Norway began in 1975.
(A)    bringing
(B)    and brings
(C)    and it brings
(D)    and it brought
(E)    and brought
答案选A,我当时排除E时看到and前面用了逗号，因为我觉得同一个主语发出的动作，不应该有逗号分隔。可是og的解释里面只字未提哦！！why??我又错了么？？

请问一下这个错误是属于effectiveness 还是correction?
