23、8能生產(chǎn)的拖拉機(jī)是往年的兩倍。 表示倍數(shù)用倍數(shù)+ as + 形容詞原形+ as +比較對象的句型。所以此句答案為C。This ruler is three times as long as that one八、動詞動詞根據(jù)其后是否帶有賓語,可分為兩類,分別是:及物動詞(Transitive Verb)、不及物動詞(Intransitive Verb),縮寫形式分別為vt. 和vi.。 在英語中按動詞后可否直接跟賓語,可以把動詞分成兩種:及物動詞與不及物動詞。 及物動詞 vt. 字典里詞后標(biāo)有vi. 的就是不及物動詞。不及物動詞后不能直接跟有動作的對象(即賓語)。若要跟賓語,必須先在其后添加上某
24、個介詞,如to,of ,at后方可跟上賓語。 及物動詞: 又稱“他動詞”。又稱“外動詞”。動詞的一種。它所表示的動作常涉及動作者以外的事物,如“吃”、“穿”、“讀”、“寫”等。字典里詞后標(biāo)有vt. 的就是及物動詞。及物動詞后必須跟有動作的對象(即賓語),并且可直接跟賓語。不及物動詞:字典里詞后標(biāo)有vi. 的就是不及物動詞。不及物動詞后不能直接跟有動作的對象(即賓語)。若要跟賓語,必須先在其后添加上某個介詞,如to,of ,at后方可跟上賓語。具體每個動詞后究竟加什么介詞就得聯(lián)系動詞短語了系動詞 1)狀態(tài)系動詞:用來表示主語狀態(tài),只有be一詞,例如:He is a teacher. 2)持續(xù)系動

28、eitheror, neithernor, (and)then等等。 notbut 意思為不是而是 not 和but 后面的用詞要遵循一致原則。 They were not the bones of an animal, but (the bones) of a human being. 比較so和 such其規(guī)律由so與such的不同詞性決定。such 是形容詞,修飾名詞或名詞詞組,so是副詞,只能修飾形容詞或副詞。so 還可與表示數(shù)量的形容詞many,few,much, little連用,形成固定搭配。so + adj.such + a(n) + n.so + adj. + a(n) +
29、n.such + n. (pl.)so + adj. + n. (pl.)such +n. (pl.)so + adj. + n. 不可數(shù)such +n. 不可數(shù)so foolish ;such a fool so nice a flower;such a nice flowerso many/ few flowers;such nice flowers so much/little money;such rapid progressso many people ;such a lot of people 十一、介詞介詞是一種用來表示詞與詞、詞與句之間的關(guān)系的虛詞,在句中不能單獨作句子成分。介
