只想分析下语法结构,
What is it that makes some people more effective than others?Is it skill,or luck,or secret knowledge?
答案
是个强调句的疑问形式
还原回来是it is What that makes some people more effective than others?Is it skill,or luck,or secret knowledge?
强调的是主语,去掉it is that ,句子就是
What makes some people more effective than others
What主语,makes谓语,some people 宾语,more effective 宾语补足语,than others壮语
Is it skill,or luck,or secret knowledge
it主语,Is系动词,skill,or luck,or secret knowledge并列表语
举一反三
