请帮忙分析此句子,Bill Gates,the chairman of Microsoft and the world’

1.把这个句子的主谓宾抽出来就是Bill Gates gave warning .除yesterday是时间状语外,其他全是主语和宾语的修饰.
同位语the chairman of Microsoft and the world’s richest man修饰BIll Gates.
由that引导出 同位语从句restrictions on the number of skilled workers allowed to enter the US put the country’s competitiveness at risk修饰warning,即为比尔盖茨给出的警告所包含的具体内容.
2.再来分析restrictions on the number of skilled workers allowed to enter the US put the country’s competitiveness at risk这一长串同位语从句,
首先抽出主谓宾,即restrictions put the country’s competitiveness at risk,主语即restrictions,谓语即put,宾语即the country’s competitiveness,at risk是宾语competitive的补足语.
接着看其他成分,skilled workers allowed to enter the US修饰number,而主语restriction的对象就是这个number.
3.按照上面句子成分的分析,翻译出来这句话就是：世界首富、微软首席比尔盖茨昨日警告说,对于掌握熟练技术的工人进入美国的限制会将美国的竞争力带入险境.这么翻译读起来不顺耳,应当翻译为：世界首富、微软首席比尔盖茨昨日警告说,限制掌握熟练技术的工人进入美国会削弱美国的竞争力.
