考情：考點(diǎn)是序數(shù)詞前用the，十八歲生日是指出生后的第十八個(gè)生日，應(yīng)當(dāng)改用序數(shù)詞。由基數(shù)詞改為序數(shù)詞這道題之所以成為全省全卷最難題，其原因是練得太少了，或者根本就沒有練過。這道題提醒我們，過去沒考的并不代表將來也不考，即“過去不代表未來”，凡是考綱內(nèi)容，我們必須全面系統(tǒng)地復(fù)習(xí)好。解法：首先要熟記基數(shù)詞和序數(shù)詞，并能默寫出來；其次要掌握考點(diǎn)歸納中的幾個(gè)相關(guān)用法。eleven→eleventh,thirteen→th12練模擬操一、單句填空1.(2018福建福州)However,intheurbandistrictofBeijinghousesalonghutongsstilloccupyone_______(three)ofthetotalarea,providinghousingforhalfofthepopulation.指三分之一，故用序數(shù)詞。third練模擬操一、單句填空1.(2018福建福州)Howev132.(2018山西孝義)Whattheylearnthelpedthemmake_____firstairplaneflightin1903.序數(shù)詞表順序時(shí)，其前要加定冠詞the。3.Heisthe_______(five)persontoaskmethesamequestion.指第五個(gè)問同一問題的人。thefifth2.(2018山西孝義)Whattheylearnt144.Ihavereadthetenthchapterbutnotthe_________(twelve).指第十二章。5.Itwasthethirdtimeoneofhiscars_________(go)upinflames.由該句型中的Itwas可知，用過去完成時(shí)。twelfthhadgone4.Ihavereadthetenthchapt156.Osakaisthe________(two)largestcityinJapan.表示“第二大”要用序數(shù)詞。7.YuriGagarinbecamethefirstman______(fly)inspace.在序數(shù)詞后或受序數(shù)詞修飾的名詞之后，通常用不定式作定語。secondtofly6.Osakaisthe________(two)16二、單句改錯(cuò)1.Hediedwithinafewdaysofhisninetybirthday.2.Thestationisaten-minuteswalkfrommyhouse.ninetieth
