A．notebook B．science book C．website D．magazine B Mangroves (红树林) are very special forests. They grow along the coastlines (海岸线). They look like tall green walls rising from the sea. Although they might seem like just trees, they do many important jobs for nature. First, mangroves play a very important role. They protect coasts from strong winds and big floods, keeping homes and beaches safe. Their roots (根) are like little cities for small animals. Small fish swim around them and birds build their homes there. What’s more, these trees are great cleaners. They take out the bad things in the seawater, making the sea cleaner and healthier. In a word, mangroves are not only beautiful but also very useful. We should protect them well. But now, mangrove forests are in great danger. People cut them down to build houses or start farms. Human activities create lots of rubbish and wastewater. This is also harmful to them. Many mangrove forests are getting smaller and many small animals in the sea are losing their homes. It’s time for us to take action. The good news is that more and more people are waking up to their importance. Volunteers (志愿者) plant new mangrove trees, and scientists study how to protect them better. We can help, too. For example, we should stop putting rubbish into the sea and take part in activities to protect mangroves. After all, saving mangroves means keeping nature healthy and it’s good for all living things. 16．What do paragraphs 1 and 2 mainly talk about? A．The green tall walls along the sea. B．The bad things in the seawater. C．The role of mangroves for nature. D．The homes of small fish and birds. 17．Why are mangroves in danger? A．Because there is too much rain. B．Because people cut them down. C．Because there are too many animals. D．Because the seawater is becoming too clean. 18．What does the underlined word “harmful” in Paragraph 3 mean? A．Bad. B．Clean. C．Direct. D．Important. 19．What do volunteers do to help mangroves from the text? A．They study how mangroves grow. B．They plant new mangrove trees. C．They stop people from cutting trees. D．They study the ways to protect trees. 20．What is the best title for the text? A．Importance of planting trees B．Activities for protecting nature C．Forests growing along the sea D．Danger caused by people’s activities C Green is more than just a color. It stands for health, youth and life. Now, it also means caring for the environment (环境). People live in a “throw-away society”. They use things for a short time and then throw them away. Why does this happen? First, there are too many choices. For example, if you are bored with your shoes after a few months, you may buy new ones and throw away the old ones. Second, many young people want the latest technology. They buy new phones and throw away the old ones. This leads to more rubbish. Recycling is easy. You can be the “Head of Recycling” in your family. Learn what can be recycled and find a place to keep them. Encourage (鼓励) everyone to think before throwing things away — can they be reused or recycled? Being green can be fun. Look at your backyard. Can you plant a tree or start a small garden? If so, get your hands dirty. You will be proud to see your tree grow and your garden produce tomatoes or strawberries. 21．What does paragraph 1 mainly talk about? A．The world. B．Our health. C．The color green. D．Our youth. 22．What does the underlined word “recycling” in paragraph 3 probably mean? A．Using things again. B．Throwing things away. C．Buying new things. D．Planting trees. 23．According to the text, which of the following can help the environment? A．Teng Fei keeps buying things. B．Fu Xing starts a small garden. C．Yaming throws things away. D．Chen Jie uses things for a short time. 24．Which picture might show the scene (场景) of the last paragraph? A． B．C．D． 25．What is the writing purpose of the text? A．To tell us to buy more things. B．To encourage us to be green. C．To show that green is a nice color. D．To explain (解释) how we throw things away. 第二节 信息还原 (共 5小题，每小题1分，满分5分) 阅读短文及文后A-F选项，选出可以填入短文空白处的最佳选项，其中有一项为多余选项。 The Earth is our precious home.

This saves energy that would have been used on the dryer.”可知，在阳光下晾晒东西可以节约能源或水。故选A。 12．细节理解题。根据“Be an advocate!”中的“Share your knowledge with others, and help them become eco-heroes too. It takes lots of people working together to make changes happen.”可知，为了号召更多的人一起工作，你应该成为一名倡导者。故选B。 13．细节理解题。根据“Save energy and water!”，“Be friendly to wildlife!”，“Be an advocate!”和“Reduce, reuse, recycle!”可知，本文一共给出了四条建议。故选B。 14．主旨大意题。根据“Here at Nature Loving Kids, we know how much you want to make a positive difference to our world! So click on the link to find out how to protect the Earth.””可知，这篇文章的目的是告诉孩子们如何保护地球。故选D。 15．推理判断题。根据“So click on the link to find out how to protect the Earth.”可知，点击链接即可阅读，因此本文可能是网上的一篇文章。故选C。 16．C 17．B 18．A 19．B 20．C 【导语】本文是一篇说明文，主要介绍了红树林的特征、重要作用（保护海岸、为动物提供栖息地、净化海水）、面临的威胁（砍伐、污染）以及保护措施。 【详解】16．通读第一段和第二段，第一段点明红树林对自然有诸多重要作用，第二段具体阐述了红树林保护海岸、为小动物提供栖息地、净化海水的功能，核心内容是红树林对自然的作用。 17．根据第三段“But now, mangrove forests are in great danger. People cut them down to build houses or start farms.”可知，红树林面临危险的主要原因是人们为了建房或开农场而砍伐它们。 18．根据第三段“mangrove forests are in great danger...Human activities create lots of rubbish and wastewater. This is also harmful to them.”可知，红树林正处于危险中，人类活动产生大量垃圾和废水，可推知这些污染物对红树林是有害的，因此harmful与bad“有害的”同义。 19．根据最后一段“Volunteers plant new mangrove trees, and scientists study how to protect them better.”可知，志愿者所做的具体帮助是种植新的红树林。 20．全文主要介绍了生长在海岸线的红树林的特点、作用、面临的危险以及保护措施。选项C“Forests growing along the sea”最能概括文章的主题对象。 21．C 22．A 23．B 24．A 25．B 【导语】本文是一篇说明文，介绍了绿色的环保含义，指出了一次性消费的问题，并倡导人们通过回收、种植等方式践行环保。 【详解】21．第一段提到“Green is more than just... It stands for...
