Answer 1

　B

　　　本題譯文：專家們說，步行是一個人保持健康的最好方法之一。preserve, stay, maintain, reserve這4個詞均有“保持”，“維持”之意。stay后可接形容詞作表語：The weather stayed wet for three days.其他3個詞均為及物動詞。Preserve(="keep" safe from decay, risk, harm, danger, going bad etc.)保存，保護：1)Policemen preserve order in the streets.(警察在街上維持秩序。) 2)We must preserve our natural resources.(我們必須保護自然資源。)3)You paint woodwork to preserve it.(你油漆木制品以防腐爛。)Maintain(="keep" up)保持，維持，維修。Reserve(="keep" for a special purpose; store)保留，預定：1)I'll reserve my opinion at his time,(這時我將保留我的看法。) 2)I'll phone up today and reserve a room.(我今天將打電話預定一個房間。)
