謝謝^^
可是我困惑的點是在於
題目只說"私校學生唸大學的機率比較大,所以如果家長想要增加孩子上大學的可能性,
應送他們去私校讀書"
並沒有說是學生自願問題還是能力問題,也沒說是學校教育能力有差異
只提出數據說"升學的可能性"的問題
如果30個公校畢業的學生自願選擇不升學,那的確還是造成了公校學校升學率比私校低
怎麼會有削弱作用?
因為題目並不是說"在願意升學的人當中",公校只有65個人能夠而私校有90人能夠
而是說整體的機率,不管那30個人是什麼原因不升學,不是都還是造成了升學率低嗎?
這題看了好多討論都還是覺得題幹說的跟大家討論的不一樣,是我的想法哪裡出了問題嗎?

: : According to a recent research study, more than 90% percent of graduates of
: : private high schools in a certain county continue their education in college.
: : By contrast, only 65% of graduates of public high schools subsequently pursue
: : college education. Therefore, if parents in the county wish to increase the
: : likelihood that their children will attend college, they should send them to
: : private rather than public schools.
: 看完之後應該要有的感覺:
: 1.抓到結論:therefore之後的一整句『如果想要讓孩子更有可能升大學,就送去私校』
: 2.往回找支持:九成以上私校學生升大學。六成五公校學生升大學。前者大於後者。

: 問削弱。
: : A Graduates of private schools typically score higher on standardized tests

: 私校學業表現好:加強而非削弱 (reverse)
: : B While private schools are typically very expensive, attendance of public
: : school is free for the residents of the county.
: 學費高低跟升學率無關。(n.r.)
: : C In comparison with graduates of private schools, a substantially greater

: 跟b一樣,財務能力或獎學金跟升學率無關。(n.r)
: : D In comparison with private schools, public schools provide more
: : opportunities for student involvement in sports and other athletic
: : activities, which almost always increase the likelihood of students’
: : acceptance to colleges.
: 你的猶豫應該是在這個選項。
: 問題是這個選項就算成立,結合題目給的事實『公校65%,私校90%升學率』並不違背
: 頂多只能知道:公校的升學率原本可能更低,是因有體育表現才加到65%
: 就算加了還是比私校低很多,還是不能推翻『讀私校更容易升大學』的結論
: : E Since most public schools are located in rural areas of the county
: : populated primarily by farmers, nearly 30% of students from public high
: : schools choose to pursue farming occupations rather than apply to colleges.
: 這題用『點出他因』來削弱結論。
: 因為學校的人口組成不同導致升學率的差異:
: 公校有30%都是農家子弟,為了家庭放棄學業
: 換句話說,如果他們不是農家子弟
: 65%+30%=95%跟私校其實有得拼。
: 總而言之這個選項的意思是:
: 真正造成公校升學低迷的原因是公校學生個人的問題跟生涯規劃,
: 跟學校的本身的品質(教學質量等等)都沒有關係。
: 所以對家長來說,選哪種學校其實沒差,問題是出在學生個人。
: 希望這樣有解決你的問題。
