LS，这个that和前面那个that都修饰cells，是定语从句的并列！充当主语，所以that不能省略

我的疑问不是that 能不能省。。。

是定语从句的并列，不是SVO，所以and只是连接两个定语从句，不需要加，
只有SVO与SVO时，and前才需要加，

不好意思，是我题目没有写清楚。


是这样的哦，


46题的题干是Researchers have found that individuals who have been blind from birth, and who thus have been seen anyone gesture, nevertheless make hand motions.....


47题的题干是Like embryonic germ cells, which are cells that develop early in the formation of the fetus and that later generate eggs or sperm, embryonic stem cells have the ability to ....


两道题中，加粗部分都分别是两个定语从句，一个有逗号连接，一个没有。为什么呢？

aeoluseros

1. and who thus have been seen anyone gesture 只是补充说明，可有可无的成分，因为可以从who have been blind from birth推导出来，所以以插入语形式出现。
2. that develop early in the formation of the fetus and that later generate eggs or sperm这两个从句之间是承接关系，后面部分不是可有可无，所以不能用插入语。
3. 47题如果and that later generate eggs or sperm用了插入语，会造成句子结构太复杂混乱。。

所以诚然如#10楼chantal891121 所说，“是定语从句的并列，所以and只是连接两个定语从句，不需要加逗号，只有SVO与SVO时（比如下面的宾语从句），and前才需要加逗号”？


Researchers have found that individuals who have been blind from birth, and who thus never seen anyone gesturing, nevertheless make hand motions when speaking just as frequent and in virtually the same way as sighed people did, and that they will gesture even when conversing with another blind person.

宾语从句也不一定加逗号的。
是否加逗号是由逻辑和句子清晰度决定的。

Researchers have found that individuals who have been blind from birth, and who thus never seen anyone gesturing, nevertheless make hand motions when speaking just as frequent and in virtually the same way as sighed people did, and that they will gesture even when conversing with another blind person.
这个句子来讲，因为宾语从句太长，所以最好and前有个逗号，来表示要出现第二个分句了。而如果两个宾从都很短，就不需要逗号了。

而对于Researchers have found that individuals who have been blind from birth, and who thus have been seen anyone gesture, nevertheless make hand motions.....
而这里，第二个定从的and前加了逗号，是因为第二个定从是可有可无的，所以就作为了插入成分。

所以，逗号的用法，还是从逻辑来分析比较好。而且其实逗号永远不会成为核心考点，所以不要过于纠结。

“是定语从句的并列，所以and只是连接两个定语从句，不需要加逗号，只有SVO与SVO时（比如下面的宾语从句），and前才需要加逗号”

M兄啊，我没说“比如下面的宾语从句”啊。。。。。

额。。。。。。苍天。。。。。我说只有SVO和SVO时，and前才需要加逗号。。。。。冤枉啊。。。。。。。

宾语从句相当于一个名词啊。。。。。。

你看我在9楼的回复，这个and+定语从句只所以加“，”是因为这个是插入语啊。。。。。完全是因为前面的thus所内含的因果关系

[quote][quote]and引起的平行啊，两边的parallelism element 成分要一致，修饰词who对who,从句主语对主语，以此类推

但是前面怎么有逗号啊

做插入语，表明这些盲人因为是先天性的，所以也没有看到过人的手势，thus表示有因果关系在里面，但是是同一类人

每次我有疑问的地方都有斑斑~真好

斑斑

这里是表示非限制性定语从句还是为了使比较清晰才在which前加逗号呢
这里做非限定性定语从句不好吧
