The Solomon Islands is a country in the Pacific Ocean. Last October, a group of scientists went there on a research trip. Guess what they found? The largest coral colony (珊瑚群) in the world!
Coral reefs may look like rocks, but they are made up of tiny animals called “polyps (珊瑚虫)”. Many polyps of the same kind form a colony. Usually, a coral reef is built out of many different colonies. This newly found coral reef, however, is just one colony. It is made up of around a billion polyps of the same kind. This huge colony is about 34 meters wide, 32 meters long and 5.5 meters high. In all, it covers about the same area as five tennis courts. It is so large that it can be seen from space. It is also very old—between 300 and 500 years!
Coral reefs play a big role in the ocean. They are home to many sea animals, such as shrimp, crabs and fish. Healthy coral reefs also protect shorelines (海岸线) from flooding during storms.
Sadly, over the years, climate change has warmed up the world’s oceans. This has caused many coral reefs to die and turn white. But this huge coral colony is very healthy. It may be able to live in warmer waters. That is good news, as this colony may help produce new coral colonies that can live in warmer waters. The huge coral colony is also important for the Solomon Islands. It was found in the waters near one of the islands, Malaulalo. The country has protected its waters in the past! It will protect the area even more in the future.
() 1. The newly found coral reef is very special because it
A. is very young
B. is much healthier than other coral reefs
C. is so large and made up of just one colony
D. is found in very warm waters
() 2. What is one of the functions of healthy coral reefs according to the passage?
A. It provides food for seabirds.
B. It helps maintain the balance of the ocean.
C. It offers a habitat for numerous sea animals.
D. It promotes the growth of seaweed in the ocean.
() 3. The newly found coral reef is good news for the environment, because it
A. may slow down climate change
B. can be used to save dead white coral reefs
C. can cool down the waters
D. may help produce new coral colonies
() 4. What would the future of the coral colony near Malaulalo be like?
A. It will be harmed by climate change.
B. It will be under the country’s protection.
C. It will be moved to a warmer place.
D. It won’t produce more new coral colonies.

答案
【主旨大意】本文是一篇说明文，主要介绍了科学家在所罗门群岛发现的世界最大珊瑚群的特点及其生态意义。
1. C 【点拨】细节理解题。根据文章第二段“This newly... around a billion polyps of the same kind.”可知，新发现的珊瑚礁特殊之处在于它由同一种珊瑚虫构成，是一个单一的巨大群落。故选 C。
2. C 【点拨】细节理解题。根据文章第三段“They are home to many sea animals, such as shrimp, crabs and fish.”可知，健康的珊瑚礁为许多海洋动物提供了栖息地。故选 C。
3. D 【点拨】推理判断题。根据文章第四段“That is good... can live in warmer waters.”可知，该珊瑚群的意义在于可能帮助培育适应温暖水域的新珊瑚群，从而应对气候变化。故选 D。
4. B 【点拨】细节理解题。根据文章最后一段“The country... more in the future.”可知，所罗门群岛未来会加强对该珊瑚群的保护。故选 B。

【分析】
做这几道阅读理解题，需先通读原文把握主旨，再针对每道题的题干关键词，定位原文对应段落的相关语句，对比选项与原文内容，排除错误选项选出正确答案。具体步骤：第1题定位“新发现珊瑚礁的特殊性”相关语句；第2题定位“健康珊瑚礁的功能”相关语句；第3题定位“珊瑚群对环境是好消息的原因”相关语句；第4题定位“Malaulalo附近珊瑚群的未来”相关语句，逐一匹配选项。
【解析】
1. 细节理解题：根据文章第二段“This newly found coral reef, however, is just one colony. It is made up of around a billion polyps of the same kind.”可知，新发现的珊瑚礁特殊之处在于它由同一种珊瑚虫构成，是单一的巨大群落，对应选项C。A选项“非常年轻”与原文“between 300 and 500 years”不符；B选项“比其他珊瑚礁更健康”原文未提及；D选项“在非常温暖的水域被发现”与原文不符，原文说它可能适应温暖水域，并非发现于暖水，故排除A、B、D，选C。
2. 细节理解题：根据文章第三段“They are home to many sea animals, such as shrimp, crabs and fish.”可知，健康的珊瑚礁是许多海洋动物的栖息地，对应选项C。A选项“为海鸟提供食物”、D选项“促进海洋中海藻的生长”原文未提及；B选项“维持海洋平衡”原文未明确表述，故排除A、B、D，选C。
