高中英语语法
China's carbon emission per head are approaching_____of European Union.
A.one B.that C.those D.what
我填的是B,

Answer 1

你的理解是正确的,此题的正确答案是B,不是A.
解析:
one,that均可用作代词,指代前面提到的名词,且均是指代同名异物.
但one为泛指,相当于a／an＋名词; that为特指,相当于the ＋名词.
所以one所指代的名词的修饰语一般为 a／an ／some ／any;
that所指代的名词的修饰语往往是the ／this ／that或其它限定词.
A chair made of steel is stronger than one made of wood.（该句中one可以换成a chair）
The water in the cup is hotter than that in the pot.（该句中that可以换成 the water）
另:one只能代替可数名词单数; that既可以代替不可数名词也可以代替可数名词单数.
其实 ,当that代替可数名词单数时,that =the one
如:I like this pen more than that one.（one代替可数名词单数pen）
Mary's handwriting is far better than that of Peter.（that代替不可数名词handwriting）
问题中句子里的emission是指光,热,气体等的"散发,排放",是不可数名词,
此句中carbon emission 前有China's限定,且所填的词有of European Union限定,
因此应是表示特指:"欧盟的碳排放" ,所以只能选B.that .
( one of European Union 还会让人误解成"欧盟的国家之一")
更正:原题中的are应为is .
