此句是名词性从句还是定语从句啊?

the new model of the car was put into production in 2007, which helped to provide another 1400 jobs.

名词性从句
因为它不修饰任何一个句子成分,而是对句子补充说明

the new model of the car was put into production in 2007, which helped to provide another 1400 jobs.

定语从句

其实你可以这么判断:
1)名词性从句一般不带逗号,而非限制性定语从句带逗号.
2)定语从句把从句去掉,意思完整.

而名词性从句是以句子来代替主句中的主语、宾语、同位语或表语,一旦去掉,主句意思不完整了。

用which 定从

定从在主句中做定语,简单的说就是主句完整,定从在主句用来修饰名词或名词性的成分。
比如:the book that I bought is good .
其中the book (that I bought) is good .括号里的就是定语,修饰先行词“the book”去掉以后留下主干 the book is good 依然正确。
而that是该定语从句的引导词,在从句中做宾语。就是只看从句成分的话就相当于 I bought the book 。
这里因为从句中和主句中都出现了“the book”,所以就用that代替一个揉到一起。

而名词性从句则必须要从句但一个名词性的成分,比如在主谓宾(就是啥啥是啥啥)句型中,你可以用从句来当主语或宾语(就是那个“啥啥”),在主系表(啥啥是咋样的)中当主语或表语(就是那个“啥啥”和“咋样的”),或者做同位语,同位语就相当于给一个名词照镜子。
和定语不同,名词性从句除了同位语从句都要在主句中有地位。
比如 (what he bought) is a book
what he bought整个的在主系表结构中作主语,如果省掉句子就变成 is a book。这显然是错的。
