Protect the coral reef
A coral reef is like a magical underwater city. It is full of colourful fish, strange sea plants and amazing coral.
In this beautiful place, small fish swim ⁽¹⁾quickly among the coral, looking for food. Big sea turtles move ⁽²⁾slowly, as if they were taking a peaceful walk. Crabs crawl (爬行) ⁽³⁾carefully in the sand, trying not to be noticed. Some small shrimps (虾) work ⁽⁴⁾really hard to clean the coral reef.
However, humans are making trouble. Some boats make loud noises when passing by coral reefs. That is not ⁽⁵⁾friendly to the sea animals. We also fish too much and pollute the sea. These human activities are hurting coral reefs, and many sea animals are losing their homes.
We need to act now. Let's stop polluting and protect coral reefs. Only in this way can we keep this type of amazing ecosystem alive.

答案： 【解析】：这是一道英语填空题，主要考查副词的使用。题目给出了一个描述珊瑚礁生态的短文，其中需要填写括号中所给单词的正确形式。这些单词都是形容词，需要转换为副词形式来修饰动词。根据英语语法规则，形容词转换为副词通常是在形容词后加-ly。同时，也要注意有些形容词变为副词时可能有拼写变化。接下来，我们将逐一分析每个空格应填的内容。
1. 对于第一个空格，quick需要变为副词形式来修饰swim，即quickly。
2. 对于第二个空格，slow需要变为副词形式来修饰move，即slowly。
3. 对于第三个空格，careful需要变为副词形式来修饰crawl，即carefully。
4. 对于第四个空格，real需要变为副词形式来修饰hard，即really。
5. 对于第五个空格，friend需要变为形容词的否定形式或意思相近的词来填空，但考虑到括号内给的是名词"friend"，其形容词是"friendly"，而题目要求的是副词形式来修饰"to the sea animals"，但在这里，"friendly"作为形容词，直接用在"is not"之后，表示“不友好的”，因此不需要变为副词。
【答案】：
1. quickly
2. slowly
3. carefully
4. really
5. friendly
