问题 Plastic bags are useful for holding many kinds of food______their cleanness toughness and low cost.
选项 A、by virtue of
B、by means of
C、at sight of
D、by way of
答案 A
解析 介词词义辨析。by virtue of侧重指“凭靠，凭借”的意思，也可表示“由于”原因，有时也说in virtue of，根据句意“塑料袋可用来装各种食品，因为它清洁、耐用又价廉”。故答案为A。by means of“用，依靠”；at sight of“一看见”；by way of“经由；当作”。
