前面有个破折号么...所以这后半句的作用就是补充说明.new and significant risks和unprecedented opportunities---是并列关系.你这句话说的颠三倒四的... 或者是种我没见过的倒装?````
正确的顺序大概是Recent years minority-owned businesses in the United States have brought unprecedented opportunities---as well as new and significant risks.
所以"as well as new and significant risks"和前面的unprecedented opportunities一起都是宾语.
关于你的补充:
recent years也不是不能做主语,不过很牵强,绝少有这么用的.句子准确的意思我觉得你得去看上下文,到底minority-owned businesses是提供了机会还是获得了机会.
宾语同位语。
brought的宾语,跟opportunities同位成分。都是宾语。
我同意as well as new and significant risks和前面的unprecedented opportunities一起都是宾语. 带来的不仅有机会还有危机 机会和危机 同时做宾语!
