Help,XDF-S4-6, use of ",", like, unlike, as

1stzhang

这个我还是保留意见。第一个题目的as是省略的 ，是正确的 。67910都是对的

joywzy

tocean0222 关于like, unlike作插入语的位置，我基本赞成。补充两句例外 。

按照英语习惯来决定——一般是出现在比较对象的后面或是提到整个句子的前面作状语。

Like XXXX,  或者(,) like XXX(,)

15. More than thirty years ago Dr. Barhara Mc—Clintock, the Nobel Prize winner, reported that genes can “jump.” like pearls moving mysteriously from one necklace to another. (A-P1-227)

16. Artificial intelligence emerged during the late 1950’s as an academic discipline based on the assumption that computers could be programmed to think like people.(D-P44-6)

as 作为比较的用法：一个句子的比较，前面要加，AS引导的从句后，也要加，

例：5. Because young children do not organize their attention or perceptions systematically, as adults do, they may notice and remember details that their elders ignore. (B-p88-6)

6. According to a recent poll, owning and living in a freestanding house on its own land is still a goal of a majority of young adults, as it was of earlier generations. (B-p162-16)


根据这些原则，我个人认为：

1，错，因为AS前少了，

2，对，

3,4对，结构与这句相似：

16. Artificial intelligence emerged during the late 1950’s as an academic discipline based on the assumption that computers could be programmed to think like people.(D-P44-6)

5,8错，原因与1stzhang同

6,7，9,10，对。

欢迎讨论。

第一个题目as是省略的，是正确的。3，4是错误的，简单名词的比较和比喻及句子的比较是不可以这样认为的

可以说得详细一点吗？谢谢。

第一个句子其实就是：Because young children do not organize their attention or perceptions （as）systematically as adults do, they may notice and remember details that their elders ignore.

Artificial intelligence emerged during the late 1950’s as an academic discipline based on the assumption that computers could be programmed to think like people.
这个句子是个比喻用法，并不可以说明什么问题

1stzhang,
你说的1句是省略了第一个as，这种用法的确存在，但是在非正式文体中，我觉得这种用法在gmat中是不允许的，as+adjective or adverb +as才是standard english;
另外我觉得第2句中as不是比喻，as在这里是“作为“的意思，不是作连词用，based on...是后置定语修饰discipline的，因此根我们所讨论的as adults do的用法是不一样的，不能由此象joywzy说的那样3、4是对的；

joywzy,

关于你举的例子，
15. More than thirty years ago Dr. Barhara Mc—Clintock, the Nobel Prize winner, reported that genes can “jump.” like pearls moving mysteriously from one necklace to another. (A-P1-227)
这个句子的like用在句尾是因为pearls后面的修饰语太长，所以后置，是一特例；

16. Artificial intelligence emerged during the late 1950’s as an academic discipline based on the assumption that computers could be programmed to think like people.(D-P44-6)
这个句子的like people是做think的宾补，不是做插入语，所以可用在句末，我已经在前面提过，比如：
He looks very like his elder brother
因此不能说由此说6、9的用法是对的；

例：5. Because young children do not organize their attention or perceptions systematically, as adults do, they may notice and remember details that their elders ignore. (B-p88-6)

6. According to a recent poll, owning and living in a freestanding house on its own land is still a goal of a majority of young adults, as it was of earlier generations. (B-p162-16)

这2个例子体现了as+subject+verb的习惯用法，在这点上我跟你的观点一致！

欢迎继续讨论和大牛指点！

我没有说as是 比喻，我是说的joy举地例子。like地用法

“你说的1句是省略了第一个as，这种用法的确存在，但是在非正式文体中，我觉得这种用法在gmat中是不允许的，as+adjective or adverb +as才是standard english;”

tocean0222 这个观点我不同意，gmat地语法是比较答案，1这种只是不正规不能说不对，但是在选择地时候不可以轻易地放弃答案

1stzhang兄，

呵呵，原来是这样，不过我更倾向于formal的用法，至少1句的用法我在正式文体我没见过，肯能是我看的还太少，不知道你能否找出个例句让我解惑呢？另外还有类似6、9两句的例子。先谢了！

siebel兄，

你也发表点意见啊？

期待ing...

tocean0222，你好！

看了你很多语法和逻辑地帖子，受益匪浅。这几个句子地比较其中（1）的确不正规
Because young children do not organize their attention or perceptions systematically as adults do, they may notice and remember details that their elders ignore.但是我们看看gmat地语法题目，有这样一个映像有些正确答案也说地很不正规，特别是在比较和省略中。有些不正规地答案经常成为正确答案。这样的例子好像在正规地问题中比较难找，我也没有见过，请各位继续补充。

（6）（9）都是插入语地使用，在张道争地语法中对插入语地论述已经比较详细，由于插入语地用法十分灵活，我也举不出什么好地例子。但是插入语只要不违背两个原则就可以：（1）不可以吧句子地主要意思部分放在插入语，在gmat语法中体现有几个题目，比如把比较中地主体部分：less than放为插入语，就是错误地；（2）不产生歧义。

请各位继续讨论！
