Question

英语试题
(with more than )half the world's annual vield of 50 million tons of soy beans,an important source of protein,is grown in the US.
括号中with more than 为什么使用错误 如何修改

Answer 1

注意句子结构 ,分析如下
(with more than )half the world's annual vield of 50 million tons of soy beans,为主语
an important source of protein为同位语
is grown 谓语
in the US状语
介词短语不能作主语,故应去掉With,改为：
More than half the world's annual vield of 50 million tons of soy beans,an important source of protein,is grown in the US.
