因为后加句子英语

肯定要接句子呀，不单单是for要接句子，只要是连词，后面都是跟句子的,介词是跟短语的。for用作连词，主要表示理由，用于引起的分句对前面的话进行解释，常用逗号把它和前面的分句分开。如：1、She was angry, for she didn’t know French. 她生气了，因为她不懂法语。2、He must be out, for there is no light in the room. 他准是出去了，因为屋里没有灯。

是的。for作连词，表示【因为】，后加句子。

because是因果连词,只能加句子;because of 是介词短语 ,只能加名词和名词性词组.

不对，前者是加句子，后者是加短语的。

No！because是连词，后面直接加一个句子。because of后面要加一个名词或动名词词组，因为of是介词。不用什么that。
