SAT數(shù)學(xué)解析:考試內(nèi)容
美國(guó)教育考試服務(wù)中心(ETS)明確規(guī)定了SAT數(shù)學(xué)試題的出題范圍。表5-1-2是它的英文原文，表5-1-3是它的譯文。盡管表中提到了一些嚇人的字 眼，如數(shù)論，概率，統(tǒng)計(jì)，集合，想象題等，實(shí)際上是一些初級(jí)的的知識(shí)，國(guó)內(nèi)高中學(xué)到的內(nèi)容是足夠的了，無(wú)需特別補(bǔ)學(xué)這些知識(shí)。至于其他內(nèi)容，對(duì)中國(guó)學(xué)生來(lái) 說(shuō)更是小菜一碟，不在話(huà)下。由此可見(jiàn)就內(nèi)容而言，中國(guó)學(xué)生所掌握的知識(shí)足以應(yīng)對(duì)SAT數(shù)學(xué)考試，故在此不再贅言。
