It is suspected that after they absorb light,they transmit the energy from this light to chlorophyll, for photosynthesis.
3. 虽然绿色屋顶的成本较传统屋顶的成本高出1.5至2倍，但支持者认为，即使不考虑节能因素，从长远看，屋顶绿化仍很划算。

While the costs of green roofs are one-and-a-half to twice that of conventional roofs, advocates say green roofs make long-term economic sense, even without factoring in energy savings.
4. 植物蒸腾作用消耗一部分降水，将它返回大气中，部分水分保存在土壤或其他植物生长媒介中，其余部分则徐徐进入城市排水系统，减少大量降雨突至时城市水系承受的压力，而扩展城市水系则需要很高的费用。

Some of that water is lost when the vegetation transpires, or "exhales" the water back into the atmosphere. Some water is retained in the soil or other growing medium. The rest enters the urban rainwater drainage system in a slow, controlled flow, a process that helps dampen high-volume rainwater surges in urban water systems, which are expensive to expand.
