since his hair too long ,he wanted to have it cut

Since his hair【was】 too long ,he wanted to have it cut.since在这里做because用.因为他的头发太长了,他想去剪头发因为和所以的两句话,都要各项句子结构完整~只有加上was,前句才有动词~======以下答案可供参考======供参考答案1:Since his hair was too long, he wanted to have it cut.因为long是形容词，用的时候必须要用be动词连用；又因为后面wanted可以看到是一般过去时，所以前面也要用一般过去时，was；（hair后面用第三人称单数）供参考答案2:Since his hair was to long，。。。没谓语啊。供参考答案3:应该是since his hair is too long 缺be动词供参考答案4:since的半句 缺了谓语，since his hair was too long, he wanted to have it cut.

我也是这个答案
