## 阅读材料

### Original assessment reading: Planting for a Coast, Not a Photograph
Mangroves grow where land and sea meet. Their roots and trunks can slow moving water and reduce some wave energy, while sheltered spaces among the roots provide habitats for young fish. These benefits have made mangrove planting a popular conservation activity.

Yet a photograph of volunteers holding seedlings tells us little about whether a forest will develop. Young trees need suitable water depth, tidal exposure and sediment. Planting on a site chosen mainly because it is easy to reach may produce disappointing survival rates. In one local restoration effort, the areas where young trees survived were not always those that volunteers found easiest to reach.

Restoration also takes time. A row of new seedlings does not provide the same protection as a mature forest, and even a healthy forest cannot remove every coastal risk. Strong storms, changing coastlines and nearby development all affect outcomes. Monitoring after several seasons is more informative than counting how many seedlings went into the ground on one day.

This does not make restoration pointless. It makes careful planning necessary. Protecting existing mangroves, restoring suitable sites and using engineering where needed can complement one another. The question for a coastal community is not which single solution looks most attractive in a campaign, but which combination reduces risk under local conditions.

## 例题解析

**示范** “Mangroves can slow waves under some conditions” 不能概括成“Mangroves prevent every flood”。can、some conditions 和every之间强度不同；议论写作可主张保护，但不能虚构保护效果。

## 练习

1. What is the main purpose? A. To report how volunteers are recruited for planting campaigns. B. To show that planting-day totals are the best measure of restoration. C. To explain the benefits and limits of restoring mangroves. D. To compare the financial costs of two coastal engineering projects.

2. 红树林可能怎样保护海岸？根据文中机制作答。

3. 为什么在不适当地点种苗可能失败？列两点。

4. 作者对硬质工程的态度是什么？给出证据而非只写positive/negative。

5. 填词：The seedlings ___ (plant) last spring. By the time the next storm arrived, some of them ___ (already / die).

6. 填词：The researchers recommend ___ (check) local conditions before planting. They also explain ___ survival rates differ between sites. 第二空为“为什么”。

7. 分析句子并译出：The areas where young trees survived were not always those that volunteers found easiest to reach. 指出两个从句各修饰什么。

8. 用50—70词概述恢复红树林的作用、条件和政策限制。

9. 为一份种植倡议改写标题和一句主张，原稿为“Plant Anywhere, Stop Every Storm!”；新文不得保证消除全部风暴。

10. 写100—120词建议短文：一个沿海社区考虑红树林恢复，如何在行动前作出负责任决定？含至少三个具体步骤和一个仍需承认的不确定性；不是写信。

## 参考答案与解析

1. C。全文解释波浪、栖息地等益处，以及选址/存活/与工程互补限制；D的成本比较没有进行；A把文中提到的志愿者当成主旨；B把作者批评的种植日数量指标当成认可的结论。

2. 根与树干增加水流通过时的阻力，可能减弱部分波浪能量；同时提供部分幼鱼栖息空间。若题只问防护机制，需写减速/减弱能量，不能只说“因为树很好”。

3. 水深或潮汐时段不适合幼苗；沉积物条件不适合；若选两项均有文本对应即可。文中也指出过度追求方便到达可能选错地点。

4. 支持依据地点组合使用不同工具，而非否定所有硬质工程。证据是末段说保护现有林、合理恢复和必要工程可互相补充；作者反对单一万能方案。

5. were planted；had already died。前空last spring过去被动；后空过去暴风雨到达前已死亡，die不及物，不写had been died。

6. checking；why。recommend后doing；why引导explain的宾语从句，说明存活率差异原因，陈述语序survival rates differ。

7. 主干 The areas were not always those；where young trees survived修饰areas，that volunteers found easiest to reach修饰those（=areas），that在从句作found宾语。译：幼树存活的地区，并不总是志愿者觉得最容易到达的地区。not always不等于never。

8. 示例：Restoring mangroves may reduce wave energy and provide habitats, but success depends on local water, sediment and tidal conditions. Planting in convenient places does not guarantee survival. Communities should protect existing forests, assess suitable sites and monitor young trees over time, while recognising that restoration may need to complement engineering rather than replace every other form of coastal protection. 量规10：作用3；条件3；行动/政策限制2；语言2。

9. 示例标题：Restore the Right Coast, Monitor the Results。主张：Well-planned mangrove restoration can contribute to coastal protection, but its benefits depend on site conditions and long-term care. 量规10：不绝对化3；适地条件3；行动性2；语言2。可用其他清晰标题，不要求押韵。

10. 示例：A coastal community should begin by mapping existing mangroves and protecting healthy areas from avoidable damage. Before planting, specialists and local residents should examine tides, water depth and sediment to identify suitable sites. A small trial can then test survival, with records kept through different seasons rather than only on planting day. The community should also compare restoration with other protection measures and plan who will maintain the site. Even careful preparation cannot determine exactly how future storms will affect the coast. The aim should therefore be to reduce risk and learn from monitoring, not to promise that trees will prevent every flood. 量规20：三具体步骤9；不确定性3；证据准确3；组织2；语言3。
