如题所述
it seems likely that extra comforts we now enjoy have increased our happiness somewhat,but that deteriorating relationships have made us less happy.这个句子中的that deteriorating 为什么要加个that，去掉that不行吗？保留that和删除that有什么不一样，谢谢
It seems likely that + 分句A ......,转折关系并列连词BUT 连接+另外一个分句B
其中分句A : 名词短语+定语从句+HAVE DONE 现在完成时形式构成 句子真正主语,前面IT 为分句A 的形式主语.
然而分句B :非谓语动词中的,动名词充当主语+HAVE DONE 现在完成时形式构成
分句A 与分句B 为并列关系, 不属于从属关系, 不属于前面形式主语IT 管辖的范围.

(1)It seems likely that extra comforts we now enjoy （句子主语部分）（IT 做形式主语）（THAT 后面句子做句子真正主语）
句子意思(1)：我们现在享受额外舒服感好象是很可能
句子意思(2)：似乎很可能，我们当前享受的附加的舒适感
(2)have increased our happiness somewhat （句子谓语部分）
在某种程度上增加了我们幸福感
(3) but （that 建议删掉） deteriorating relationship have made us less happy （动名词短语做主语）（转折关系并列分句）（BUT 为转折关系并列连词，用来连接另外一个独立的分句，他们是一种并列关系，不属于一种从属关系，不属于第一个IT 形式主语对应真正主语范畴.）
