That weather, and the sheer calorific spend of living and working at a median altitude of 1,300 metres介词短语作定语·修饰 spend, has made the traditional cuisine much sturdier here than elsewhere in Spain比较状语从句(省略 it is).
主干:(That weather)+ and(the sheer calorific spend …)→ 并列主语 + has made(谓)+ the traditional cuisine(宾)+ much sturdier(宾补)
语法点:两个主语被作者视为同一个复合原因(天气 + 热量消耗),故谓语用单数 has made,而非 have made。
标点提示:spend 后面有逗号,说明并列主语是 "That weather" 与 "the sheer calorific spend…",不要把 spend 当成与 weather 并列的第三项。
参考译文:那样的天气,加上在海拔中位数 1,300 米处生活与劳作所带来的巨大热量消耗,使这里的传统饮食比西班牙其他地方要扎实得多。
