If people take their broken things to Repair Cafés, they can find tools and volunteers 24 are ready to help.

The goal here is to limit carbon dioxide (二氧化碳) and other greenhouse gases, which are closely connected to the big problem of global-warming (全球变暖). Way 1:Bring your own cup to Starbucks. You’ll get a 10-cent discount, and it’s one less paper cup to end up in a dustbin. The store won’t create more waste when they throw away a cup. Way 2 : Turn off your computer. When in standby mode (待机模式), your PC is still using energy. Turning off a monitor (显示器) for 40 hours a week may only save $5 a month, but it reduces CO2 by 750 pounds! Way 3: Reuse plastic bags. Instead of throwing away 100 billion plastic bags a year, try and get a second, third, or tenth use out of them. Better yet, next time you shop, try a reusable bag. You’re reducing pollution. The amount of oil it would take to make just 14 plastic bags would run your car for one mile. Way 4: Use recycled paper in the bathroom. Most of the toilet paper we use is made from trees found in forests previously untouched by humans. If every family took the place of one roll of toilet paper with a recycled one, 424, 000 trees would still be standing. Way 5: Plant a free. Adding green to your garden is beautiful and earth-pleasing. Just one tree will help make cleaner air and save the environment from 5, 000 pounds of hot carbon dioxide each year. 1．What is happening when your PC is in standby mode? 2．What’s the advantage of using recycled paper in the bathroom? 3．How many ways are mentioned in the passage?   4．What other ways do you usually do to protect the environment? 5．What’s the passage about? 二、短文填空 （一） 阅读下面短文，用括号内所给词的适当形式填空，必要时可加助动词。 March 22nd is World Water Day.

Unfortunately, in many parts of the world, men have not realized that trees are the most important. In their eagerness (渴望) to make money from trees, some people have cut trees down in large numbers, only to find that without them they have lost the best friends they had. And besides, they are usually too careless to plant and look after new trees, so the forests slowly disappear. This doesn’t only mean that men will have fewer trees. The results are even more serious: where there are trees, their roots break up soil—allowing the rain to sink in and also bind (绑定) the soil, thus preventing it from being washed away easily, but where there are no trees, the rain falls and carries away the rich top-soil. When all the top-soil is gone, nothing remains but worthless desert. 36．The most important service of trees to men is ________. A．they give people wood and other products B．they give people shade and cool C．they help people prevent drought and floods D．they help people make money 37．Land becomes desert after all trees cut down, because ________. A．there is too much rain B．there are no more trees to keep the rich top-soil from being carried away by floods C．there is a strong wind D．roots of trees break up the soil 38．What does the underlined word “roots” mean in Chinese?

A．Tree roots can make the top-soil rich and the ground hard. B．Trees can make the rain sink into the ground. C．Trees can prevent drought and floods. D．Tree roots can break up soil. 5、 五、短文填空（共10小题；每小题1分，满分10分） 阅读短文，在空白处填入一个适当的单词或括号内所给单词的适当形式。 “What if one person picked up one piece of rubbish every day?” said Zach Choboter. “That is such a little thing. But 41 everyone did that, imagine how clean the world would be.” Many years ago, Zach 42 (live) in Whistler, a famous place in Canada for skiing. He met many people who loved outdoor sports and started to be 43 (interest) in skiing there. Since he loved skiing, he decided to do that for the environment. “I was learning about bees at that time, and the more I learn about something, the more I care,” he said. “Bees are amazing. They play 44 big role in the environment.” In fact, with the help of pollination (授粉) made by bees, we can get more fruit that is 45 (big), brighter, and sweeter. Sadly, bees are facing a hard situation now because of climate change and less living space for them. As a result, Zach started the organization Blading for Bees. It 46 (found) mainly for the protection of bee population. In 2021, Zach spent 91 47 (day) finishing a 10,093-kilometre rollerblading trip. That was enough to break the Guinness World Record for “Longest Continuous Journey on Rollerblades”. He wanted to bring people together to help the bees.

My name is Li Hua. As we know, we have only one earth. But in recent years, many disasters have happened on the earth and unusual weather has appeared very often. As students in this city, what should we do? Firstly①， we need to spread something to protect our environment. For example, we can give talks on how important the environment is. It's bad for our health to live in a bad environment. Secondly①， we're supposed to save water and energy in our daily life. Thirdly①， in order to reduce air pollution, it's better to go to school by bus, by bike or on foot. Fourthly①， the garbage can be divided into four categories: recyclable, harmful, dry and wet waste. Before putting the garbage into the dustbins, we should learn how to sort it. And we can use cloth bags instead of plastic bags. Last but not least①， no business, no killing. It should be noted that② there are never wild animals as food because they are part of the environment. I hope to make more rules to protect wild animals. Thus, if I were wild animals, I would be happy and get on well with humans.③ If we all keep doing these things, I believe the environment will be better and better.

Unfortunately, in many parts of the world, men have not realized that trees are the most important. In their eagerness (渴望) to make money from trees, some people have cut trees down in large numbers, only to find that without them they have lost the best friends they had. And besides, they are usually too careless to plant and look after new trees, so the forests slowly disappear. This doesn’t only mean that men will have fewer trees. The results are even more serious: where there are trees, their roots break up soil—allowing the rain to sink in and also bind (绑定) the soil, thus preventing it from being washed away easily, but where there are no trees, the rain falls and carries away the rich top-soil. When all the top-soil is gone, nothing remains but worthless desert. 36．The most important service of trees to men is ________. A．they give people wood and other products B．they give people shade and cool C．they help people prevent drought and floods D．they help people make money 37．Land becomes desert after all trees cut down, because ________. A．there is too much rain B．there are no more trees to keep the rich top-soil from being carried away by floods C．there is a strong wind D．roots of trees break up the soil 38．What does the underlined word “roots” mean in Chinese? A．树干 B．树根 C．树皮 D．树种子 39．People cut down a large number of trees because ________. A．they wanted to get wood from them B．they wanted to get money from them C．they didn’t realize the importance of them D．all the above 40．Which of the following is NOT true? A．Tree roots can make the top-soil rich and the ground hard. B．Trees can make the rain sink into the ground. C．Trees can prevent drought and floods. D．Tree roots can break up soil. 【答案】36．C 37．B 38．B 39．D 40．A 【导语】本文主要讲述树木在提供产品、给予阴凉、防止干旱洪水等方面对人类至关重要，指出人们因渴望赚钱和忽视树木重要性而大量砍伐，导致森林消失、表土流失成沙漠，强调树木对生态环境的关键作用 。 36．细节理解题。文章虽提到树在提供木材等、给予阴凉、防止干旱和洪水这三方面对人类有用，但从“Unfortunately, in many parts of the world, men have not realized that trees are the most important”以及后文阐述树对保持水土等作用可知，防止干旱和洪水是最重要的。故选C。 37．细节理解题。根据“where there are trees, their roots break up soil—allowing the rain…but worthless desert”可知，树木被砍伐后，没有树来阻止肥沃的表土被洪水冲走，土地就变成了沙漠。故选B。 38．词义猜测题。根据“where there are trees, their roots break up soil—allowing the rain to sink in and also bind the soil”可知，能分解土壤、让雨水渗入并固定土壤的应该是“树根” ，故选B。 39．细节理解题。根据“In their eagerness to make money from trees, some people have cut trees down in large numbers”可知人们为了赚钱砍伐树木，同时也因为“many men have not realized that trees are the most important” ，没意识到树的重要性；另外，树能提供木材，这也是人们砍伐的一个因素。所以A、B、C选项都正确，故选D。 40．细节理解题。根据“where there are trees, their roots break…away the rich top-soil”可知，树根分解土壤让雨水渗入并固定土壤，但未提及能使表土肥沃且地面变硬，A错误，故选A。 5、 五、短文填空（共10小题；每小题1分，满分10分） 阅读短文，在空白处填入一个适当的单词或括号内所给单词的适当形式。 “What if one person picked up one piece of rubbish every day?” said Zach Choboter. “That is such a little thing. But 41 everyone did that, imagine how clean the world would be.” Many years ago, Zach 42 (live) in Whistler, a famous place in Canada for skiing. He met many people who loved outdoor sports and started to be 43 (interest) in skiing there. Since he loved skiing, he decided to do that for the environment. “I was learning about bees at that time, and the more I learn about something, the more I care,” he said. “Bees are amazing. They play 44 big role in the environment.” In fact, with the help of pollination (授粉) made by bees, we can get more fruit that is 45 (big), brighter, and sweeter. Sadly, bees are facing a hard situation now because of climate change and less living space for them. As a result, Zach started the organization Blading for Bees. It 46 (found) mainly for the protection of bee population. In 2021, Zach spent 91 47 (day) finishing a 10,093-kilometre rollerblading trip. That was enough to break the Guinness World Record for “Longest Continuous Journey on Rollerblades”. He wanted to bring people together to help the bees.
