coastline, bluff, wave, energy, protect, tool, map, precise

点一下不认识的单词。

Maine has a very long coastline of 5,000 miles. Almost half of it, 48 percent, is made of bluffs. Bluffs are high cliffs near the sea. These areas can change because of the waves and weather.

The old shoreline maps are more than 20 years old. They do not show the new buildings or changes in the bluffs. So, three groups in Maine worked together to make new maps. They used special data from satellites and NOAA to make the maps more exact.

The new maps also show how waves move and how big they are. This helps people understand the energy of the waves along the coast. It is important for planning how to protect the shoreline from damage.

These maps will be used in a new tool called the Living Shorelines Decision Support Tool. This tool helps planners make better decisions to protect the coast. The new maps are more precise and better than the old ones for this work.

难句解析

  1. 1

    They do not show the new buildings or changes in the bluffs.

    这里的“show”不是“展示”，而是“反映、包含”的意思，指地图上没有包括新建筑或悬崖的变化。意思是：这些旧地图没有反映新建筑和悬崖的变化。

  2. 2

    They used special data from satellites and NOAA to make the maps more exact.

    “from satellites and NOAA”是并列结构，NOAA 是美国国家海洋和大气管理局。整句意思：他们用卫星和 NOAA 的特殊数据，让地图更精确。

  3. 3

    These maps will be used in a new tool called the Living Shorelines Decision Support Tool.

    called 后面是“被称为”的意思，修饰前面的“a new tool”。整句意思：这些地图将用于一个新工具，这个工具叫做 Living Shorelines Decision Support Tool。

本篇语法

比较级和最高级 (Comparatives and superlatives)

比较两个事物用比较级：短形容词加 -er，长形容词前加 more，后面用 than：Tom is taller than Ben. This book is more interesting than that one. 三个或以上比较用最高级：the + -est 或 the most：the tallest, the most beautiful。不规则：good → better → best, bad → worse → worst。

adj-er / more adj + than · the adj-est / the most adj
