如何区分主从句哦

如题所述

Furthermore, he (a successful scientist) is not only critical of the work of others,but also of his own, since he knows that man is the least reliable of scientific
instruments and that a number of factorstend to disturb impartial and objective investigation.
这个句子的主句是he …his own。从句是since引导的原因状语从句
从句一般都有引导词或者叫连接词、关联词。如果没有就看句子成分,如果一个句子中出现两个或以上的主谓宾或者其他完整的句子类型,那就要判断是否是从句。
如:
I know he is a farmer. 其中
he is a farmer做主句谓语动词know的宾语,所以是一个宾语从句。

since前面都是主句,since后面都为从句,是since引导的原因状语从句。
