雅思写作小作文范文 雅思写作流程图flow chart 洪水与堤防

今天我们雅思写作小作文范文的相关文章来研究下流程图。流程图是雅思写作考试中比较少考到的一种题型。有些老师甚至会在课堂上直接略过它。但近年来,这种非主流题型的出现频率明显上升,因此大家还是要好好准备一下,最起码知道基本的答题套路才行。老烤鸭小编搜集了一篇考官范文,以供大家参考。

雅思写作小作文题目

The diagrams below show how houses can be protected in areas which are prone to flooding.

Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

雅思写作小作文范文

The diagrams compare two different methods of defense for homes which are at risk of being flooded.

这张图表比较了两种保护方案。他们可以用于保护面临洪水威胁的房子。

The key difference between the diagrams is that they show flood protection with and without a stopbank. In either case, the at-risk home is raised on stilts above ground level.

图表中的关键差别在于在洪水防治的过程中有没有防水堤。在两种情况下,处于风险之中的房子都由柱子支撑着脱离了地面。

The first diagram shows how a stopbank acts as a flood barrier to stop river water from flooding homes. The stopbank is a small mound of land next to the river that is higher than the 100-year flood level and prevents the river from bursting its banks. Nearby houses can be built on stilts to prevent flooding from rainwater, and a floodgate beneath the stopbank can be opened to allow this ‘ponding’ to drain off into the river.

第一张图表展示了防水堤如何作为阻挡洪水的障碍防止水流淹没房子。防水堤是一块紧挨着河流的突起的土堆。它比百年洪水线要稍微高一些,以防止喝水漫过堤岸。附近的房子被建造在柱子上以防止由雨水导致的洪水。同时,防水堤下面的门可以打开使得积水可以抽空到河水中。

When there is no stopbank, as shown in the second diagram, there will be nothing to stop the river from flooding. In this case, the solution is to put buildings on stilts. The height of the stilts is measured so the floor of the house is 300mm above the 100-year flood level. This measurement is called the ‘freeboard’.

如同第二张图表展示的那样,当没有防水堤的时候,没有任何东西能阻止河水泛滥。在这种情况下,解决方案是将建筑物建造在柱子上。珠子的高度经过计算和测量。从而使房子的底部高于100年洪水线300毫米。这种措施被叫做“排高”。
