可以帮我剖析一下这两个句子吗？
1.Mr Scott was also encouraged by consumer spending, which he said was driven by higher tax refunds and eventually improvements in the jobs picture’.
2.He stressed that, while gross margin was better than originally forecast, the improvement was thanks to the mix of merchandise, not higher prices.
Mr Scott （主语）//was also encouraged（谓语）// by consumer spending, （状语）//which he said was driven by higher tax refunds and eventually improvements in the jobs picture’.（非限制性定语从句）
参考译文：斯科特还遭到买家支出的激励。他表示买家支出的推进原因包含更高的退税和“就业形势/前景/情况的最后改变”。
备注：引导非限制性定语从句关系代词which，作定语从句中的宾语从句的主语。
He（主语）// stressed（谓语动词） that, while gross margin was better than originally forecast, the improvement was thanks to the mix of merchandise, not higher prices.（宾语从句）
参考译文：他强调，虽然毛利率要比刚开始的预期更好，但这要归功于产品的组合，而不是更高的价格。
备注：that宾语从句里又包括一个while从属连词引导的让步状语从句。
