Question

请划分句子成分

The polulation of the U.S. is 309 million,making it the country with the largest number of native English speakers.

Answer 1

The polulation 是主语of the U.S.是定语
is 是系动词309 million是表语,
making it the country with the largest number of native English speakers.是现在分词短语作伴随状语

其中making 是现在分词it 是现在分词的宾语 指代the U.S。
the country 是宾补with the largest number of native English speakers是定语修饰the country.

追问

请问如何翻译，为什么不是现在分词短语作后置定语，能改为复合句吗

追答

原句=The polulation of the U.S. is 309 million,and the polulation makes the U.S. the country with the largest number of native English speakers.

当然 说成非限制性定语也能说通
原句=The polulation of the U.S. is 309 million,which makes the U.S. the country with the largest number of native English speakers.
