句子分析：
1）主句China's "remarkably strong" economic growth outlook was a bright spot （中国“异常强劲”的经济增长景象是一个亮点）。其中主语是outlook，谓语是was，加后面表语a bright spot，系表结构。
2）in a world economy that was otherwise largely slowing（在大大放缓的世界经济中）,是状语，其中that was otherwise largely slowing是World economy 世界经济的定语从句。
3）but that it was threatened by high domestic inflation that may be spilling over to the rest of the world.（不过这一景象受到可能会蔓延到世界其他国家的国内高通货膨胀的威胁），这是由but that引导的与主句的并列句，it在并列句中是主语，它还是前面的outlook。that may be spilling over to the rest of the world.
是一句定语从句，修饰inflation（通货膨胀）。

中国的“非常强劲”的经济增长前景的一个亮点，在世界经济中是其他主要放缓，但它受到了国内高通货膨胀，可能会蔓延到世界其他地方。
