Question

【題目】Many_______ trees must be planted every year.

A. thousands B. thousand of C. thousands of D. thousand

Answer 1

【答案】C

【解析】句意：每年好幾千的樹必須被種植了。thousands 千，復數(shù)形式；thousand of形式錯誤；thousands of成千的；thousand千。many thousands of成千上萬的，修飾可數(shù)名詞trees。thousand是一個數(shù)詞，與基數(shù)詞搭配時，不用復數(shù)，表示確切的數(shù)量；或者構(gòu)成短語thousands of，表示不確切的數(shù)量。故應(yīng)選C。
