我也有同样的问题。

prep破解版的注释是说Unlike后面不能跟doing，这个讲法值得商榷。OG11版 语法练习的前言里面（P632）对于As/like 的解释里明确提到like可以跟ing形式As不可以“Like is generally used as a preposition, and therefore is followed by a noun, an object pronoun, or a verb ending in‘ing'” 并给出例句 “There's nothing like biking on a warm, autumn day.”

再来看一道OG11的题目P658 T122：

More than 30 years ago Dr. Barbara McClintock, the Mobel Prize winner, reported that genes can "jump," as pearls moving mysteriously from one necklace to another.

A.as pearls moving mysteriously from one necklace to another

B.like pearls moving mysteriousely from one necklace to another

C.as pearls do that move mysteriousely from one necklace to others

D.like pearls do that move mysteriousely from one necklace to others

E.as do pearls that move mysteriousely from one necklace to some other one

最佳选项是B。

like 可以跟，unlike 为什么就不能跟 doing 了呢。所以C不对是不是应该有别的理由呢？

我语法不好,但说说自己的看法.

1cooking with spices和2taking spices for medicinal逻辑意思真的对等吗?

我感觉这个题是比较作饭用香料和医药用香料,重点比较的是香料在各自方面的...

大家觉的呢,所以,1和2不是很对等啊

D的比较侧重点就相同了

谢谢,

吃好饭再来看看还发现C有个致命伤：in large quantities 是形容可数名词的，D的主语spices复数 are taken in large quantities，很对；C的主语是动名词，不可数 taking spices for medicinal usage is done in large quantities，很错。

个人认为

like有2种用法，一个是比喻的like，像什么，就好像act like a fool

还有一个是对比like a, b do something.

当用来对比2个东西时，如果用Like A doing something, B doing 等 是否换成As从句或者while,whereas对照更为简洁呢？

当用比喻时，like就不能用as等代替了， 所以og11-122题一定要用的like

此题

不是说正如pearls能神秘的从一个项链到另一个，Genes can "jump"

而是说Genes can "jump"，像pearls从一个项链move到另一个一样.

第一个正如指某个确定存在的事，第二个指比喻虚拟的事

不知道说地对不对，或者说清楚没有

C怎么看都觉得是把cooking这件事儿和taking这件事儿比，这两个逻辑上不能比吧!!
