OG 163 关于and连接的问题

163. Found throughout Central and South America, sloths hang from trees by long rubbery limbs and sleep fifteen hours a day, moving infrequently enough that two species of algae grow on its coat and between its toes.

1. sloths hang from trees by long rubbery limbs and sleep fifteen hours a day, moving infrequently enough
   
   
   
   
2. sloths hang from trees by long rubbery limbs, they sleep fifteen hours a day, and with such infrequent movements
   
   
   
   
3. sloths use their long rubbery limbs to hang from trees, sleep fifteen hours a day, and move so infrequently
   
   
   
   
4. the sloth hangs from trees by its long rubbery limbs, sleeping fifteen hours a day and moving so infrequently
   
   
   
   
5. the sloth hangs from trees by its long rubbery limbs, sleeps fifteen hours a day, and it moves infrequently enough

D, the best choice, correctly subordinates sleeping and moving to hangs while using the idiomatically correct phrasing so (infrequently) that.... The pronoun its shows clearly that the limbs belong to the sloth, not the trees. Choice A illogically coordinates hang and sleep and, like E, uses the unidiomatic expression infrequently enough that. B creates an awkward and nonparallel series: sloths hang ..., they sleep ..., and with.... C creates a confusing and absurd image with use their... limbs to hang ..., sleep ..., and move .... A, B, and C all mistakenly use the plural sloths, which does not agree , with its coat and... its toes. E wrongly coordinates hangs and sleeps and violates parallelism by inserting it before moves to create a new independent clause.

不知道是现在脑子转不过弯，还是有点钻牛角尖，刚才查了下以前的贴，好象没有我要的答案，所以只能又发新贴了，还请NN帮忙解答。

问题是：关于A的解释，除了ENOUGH THAT的错误外，还说把HANG 和 SLEEP两个动作COORDINATE不和逻辑，不明白为什么不合逻辑。如果说HANG 和 SLEEP两个动作不能并列的话，我就不明白为什么SLEEP变成分词做伴随状语怎么就合逻辑了，难道D中不也是表示HANGS FROM TREES的同时SLEEPING 。。。吗？

一点意见

Found throughout Central and South America, sloths hang from trees by long rubbery limbs and sleep fifteen hours a day, moving infrequently enough that two species of algae grow on its coat and between its toes.

你看A的话.树懒用他长长的尾巴把自己挂在树上以及一天还要睡上个15个小时.你再说他很少移动这不是废话吗?谁睡觉还在那跳舞又不是梦游.所以逻辑上不好说,语法硬要讲也没有大的问题.

Found throughout Central and South America, the sloth hangs from trees by its long rubbery limbs, sleeping fifteen hours a day and moving so infrequently that two species of algae grow on its coat and between its toes.

D的翻译我认为应该是:...树懒通过它长长的尾巴挂在树上,(在树上干什么?---伴随一个动作)一天睡15个小时以及很少移动.睡觉很移动在这里用非谓语动词的形式表伴随.你说同时发生也说得过去.

sleep和move infrequently是并列的动作, 它们共同的后果是SLOTH身上长藻了

挂在树上不代表猴子不动, SLEEP和MOVE INFREQUENTLY是用来补充HANGE的状态, 然后这种静止的状态导致SLOTH身上长藻了

OG上有很多的题目考动作并列层次的问题, 如果并列的层次不对肯定会导致逻辑的错误.

最近也在复习SC, 越来越觉得SC实际上是在通过语法考逻辑思维

高见！
