servation

[答案] D. conservation.

[注释] conservation 保存(自然资源等) the conservation of soil and water 水土保持; the law of conservation of energy 能量守恒定律。observation观察; reservation (旅馆房间、戏院座位等的) 预定; 保留 (意见) ; [美]保留地：1) Have you make your reservations? (你预定了没有？) 2) I will accept the suggestion without reservation. (我将毫无保留地接受这项建议。) 3) The government has set apart Indian reservations. (政府已经划出印地安人保留地。) preservation保存 We must strive for the preservation of our natural resources. (我们必须努力保护自然资源)conservation, preservation, reservation从汉语概念出发时很容易混淆。Conservation是动词conserve派生的名词, 与原来动词的意义相同, 表示"保持、保存”时, 强调“珍惜、节用。 Preservation是动词preserve派生的名词, 强调“收藏、保存”使之完好无损或质量不变; 常与食品、博物馆收藏的展品等词搭配。Reservation主要指意见、看法等的“保留”; 作“保留地”解时, 尤指美国印地安人保留地或澳大利亚土著民族保留地。本题指自然生态的保持, 用conservation最切题。
