SAT OC语法题
【A recent discovery is the finding that】 people who both drink and smoke 【are】 greater cancer risks than those who do only of these things.
A.It has recently been discovered that
主语从句结构
但是我就想问原句有没有语法错误
A recent discovery作主语 is 作谓语 the finding做宾语然后that.修饰finding请问可以吗?
还有那个are没问题吗...不用改成have吗?
