Which of the following is true according to the text?
A. Personal search agents are indispensable to job-hunters.
B. Some sites keep E-mailing job seekers to trace their demands.
C. Personal search agents are also helpful to those already employed.
D. Some agents atop sending information to people once they are employed.
首先,分析A選項,其中的表語錯誤,因為在原文中并未出現“indispensable”,原文中只是提到有人用這個搜索工具找到了工作,但并未說明這樣的工具對于找工作的讓你是必需的(indispensable)。因此這屬于斷章取義錯誤;B選項是主干錯誤選項,網站并不會發郵件給那些找工作的人,去尋找他們的需求,而是回應他們的需要;而C選項可以定位到文中最后一段的第四行:Although happily employed, Redmon maintains his agent at CareerBuilder. 將those already employed 可以同義替換Redmon,即已經工作的人。雖然快樂地工作著,Redmon依然在CareerBuilder保留著他的代理。同時,在文中的最后一句,“Working with a personal search agent means having another set of eyes looking out for you.”即,使用個人搜索代理,就意味著有另外一雙眼睛在為你守望。這樣“another set of eyes looking out for you”就可以同義替換到“helpful”;而D選項題干中的“once they are employed”則是強加的因果關系。同時文中并未說,在找到工作后也可以保留agent,也就意味著agents還會發郵件給他們。因此D選項屬于無中生有。
