he said (that) the text was very difficult and that we had to work hard at it.谁能分析一下这个句子啊

双宾语从句
that 后面是他说的内容
前面是said过去式，所以从句里面的动词用过去式

这是一个宾语从句，意思是，他说这个测试很难，我们不得不辛苦的在这上面工作
满意请采纳

他说：“这测试很难，我们不得不朝这个方向努力工作。”

第一个that后面接的是said的宾语从句，第二个that也是一样，两个从句是顺接关系。
注意：and后面接的宾语从句关系代词that不能省略。
翻译：他说这篇课文很难，所以我们需要努力去掌握它。

he said that the text was very difficutl 宾语从句：他说那篇课文很难and that we had to work hard at it 与that the text was very difficutl 平行,相当于：he said that we had to work hard at it 也就是说他...

相当于he said that the text was very difficult and (he said) that we had to work hard at it. 省略了（）中的内容，因为前后一致，所以其实是两个宾语从句用and连接。
中文：他说这次的文章非常难，并说对此我们需要努力。
