The moment a child begins school,作状语,这个状语里面有个定语从句,省去了which：在小孩一开始上学的时候.he enters a world of vicious competition where success and failure are clearly defined and measured.he 作主语,enters 作谓语 competition 作宾语,a world of vicious 作定语 where success and failure are clearly defined and measured.这个是定语从句.can wonder 作谓语.increasing number of “drop-outs” 同样是宾语.冒号后面解释 drop out ：
who are written off as utter failures before they have even embarked on a career 定语从句.are written是系表结构.
第二句,As anxiety-makers 作为焦虑者,是状语,examinations 主语 are 系动词 none 表语.
That 主语 is because so much depends谓语 on them 整句话是一个宾语从句哈..They 主语
are 系动词作谓语 the mark表语 of success of failure （in our society.状语）（Your whole future 主语）may be（谓语）
decided被动（ in one fateful day.状语）it doesn’t matter that you weren’t feeling very
well,or that your mother died.
主语从句.
that you weren’t feeling very
well,or that your mother died ＋doesn’t matter.所以doesn’t是谓语.
（No one 主语）（can give of 谓语）（his best宾语）（ when he is in mortal terror,or after a
sleepless night定语 两个定语从句并列）,yet this （主语,指逗号前半句）is谓语 precisely （what the examination system （expects谓语） him
to do.宾语从句）
