Question

【題目】As _____ rule, apples are sold by _____ weight and eggs by _____ dozen.

A. a; 不填; theB. a; the; the

C. a; a; theD. the; 不填; 不填

Answer 1

【答案】A

【解析】句意：一般說來，蘋果按重量賣，雞蛋成打的賣。as a rule(通常地)是固定詞組。在度量名詞前，表示付工資、賣、租等方式時用the，又如paid by the hour/day/month/piece，sold by the yard/dozen/ton，比較by weight(按重量)。故選A。
