In the Indian state of Assam, growing numbers of tea farms are destroying the Asian elephant's habitats and endangering their population.Much of the forest land where tea is grown in Assam is flat and thus farmers must dig drainage trenches or small channels to prevent water from accumulating and hurting the plants.The trenches, however, can be death traps for the elephants. Since the elephants need to use tea plantations as landmarks when traveling in forests, they almost unavoidably have to move through the farms.Moreover, because there are fewer humans around, pregnant females often use tea-growing areas as safe shelters to give birth.But baby elephants, still not used to rough ground may easily fall into the trenches and get hurt. Once injured, they might not be able to climb out.When mothers try to dig their babies out, both may be trapped in thick mud, even be killed.Furthermore, elephants are known to resist leaving their sick or dying behind, and a group may stay at a trench with a trapped baby for hours, unwilling to move on until all hope is lost. Is there possibility for elephants to live in harmony with the booming tea business? Elephant Friendly Tea is an organization that takes the initiative to make it possible.The organization encourages consumers to choose brands that take an active part in elephants protection, and has established a certification program to reward tea growers who are doing it right.Until now, only smaller tea brands have been certified, but awareness is growing.The organization believes that people may be encouraged to buy elephant-friendly brands when they know more about the risk tea can cause to these endangered animals. 语篇解读：本文是一篇说明文。主要介绍了茶叶种植对亚洲象的生存环境造成威胁及Elephant Friendly Tea组织为保证大象安全和茶叶生意的发展所做出的努力。 1．Why do farmers in Assam dig trenches? A．To trap elephants. B．To mark boundaries. C．To protect tea trees. D．To expand tea farms. 解析：细节理解题。根据第二段中“Much of the forest land ... hurting the plants.”可知，茶农挖沟渠是为了避免雨水集聚而损害茶树。故选C项。 √ 2．What can we say about baby elephants? A．They get stuck by the sharp branches of the tea trees. B．They have difficulty moving around the uneven fields. C．They might miss the landmarks while traveling in forests. D．They fail to find a safe shelter when climbing out of trenches. √ 解析：细节理解题。根据第三段中“But baby elephants, still not used to rough ground may easily fall into the trenches and get hurt.”可知，在不平整的地面上行走，小象面临许多困难，很容易掉进沟渠里。故选B项。 3．What does “it” underlined in the last paragraph refer to? A．Encouraging consumers to choose high-quality brands. B．Rewarding tea growers for protecting the environment. C．Promoting elephant-friendly trenches and organizations. D．Creating a win-win situation for elephants and tea farms. √ 解析：代词指代题。根据最后一段画线词所在句可知，该组织采取行动，致力于保证大象安全和茶叶生意的发展，此处it指代上文提到的“elephants to live in harmony with the booming tea business”，即大象保护和茶业发展的双赢局面。故选D项。 4．Which is the most suitable title for the text? A．The Trenches Pose Threats to Elephants B．Habitat Loss Affects Endangered Animals C．Growth of Tea Gardens Benefits Plantation D．Farms Sponsor Environmental Organizations √ 解析：标题归纳题。根据第二段中的第一句和最后一句并结合下文茶农挖的沟渠对大象造成的具体危害的描述可知，本文主要介绍了茶叶种植尤其是茶园内的沟渠对亚洲象的生存环境造成了威胁。故A项为本文最佳标题。 Ⅱ.阅读七选五 We all want to save money, and with the cost of living on the rise, it's become more important than ever to watch what we spend. One of the biggest increases in our spending at the moment is on energy. 5 That's why many of us are looking at ways to save energy. 6 To try to achieve this, new homes in some countries will be banned from fitting new gas and oil boilers.Having a heat pump (热泵) instead can help save energy, but it's unaffordable for many people, unless they've got spare cash. For people who have to live within a tight budget, there are some low-budget solutions to lower energy usage. 7 Adding rolled-up towels to block the gaps will help. Investing in new double glass windows will certainly prevent heat from leaking, but if it's still too costly, it might be worth using some heavy curtains to stop the heat escaping. There are lots of other little things we can do around the home that will help save energy, don't cost a fortune and just require changes to our behaviour. They could be as good as fitting or making something. Put covers on pots and pans when cooking — the food will be ready more quickly. Don't overfill the container when boiling water, and don't leave electrical items on standby. 8 So, we're being encouraged to make the use of fuel more efficient. 9 We need to do it to reduce our carbon footprint, so that our energy usage doesn't cost the Earth. A．Warm air can escape from rooms easily. B．It's advisable to make the best of energy. C．But our main aim isn't just a financial saving. D．The oil, gas and electricity used in our homes are costly. E．We should consider more about the possible ways to deal with it. F．Making our home more energy-efficient is the obvious way to save money. G．A combination of such small measures could reduce energy bills by about 10%. 语篇解读：本文是说明文。文章主要介绍了随着生活成本的上升，人们都想减少日常开销，目前我们支出增长最大的方面之一是能源，文章给出了一些在家中节约能源，减少开支的方法。 5．选D　空前提到目前，我们支出增长最大的方面之一是能源，空后提到这就是为什么我们一直在思考节能的方法，故空处内容应涉及能源方面的花费。 6．选F　下文提到为了实现这一目标，一些国家的新住宅将被禁止安装新的燃气和燃油锅炉，用热泵代替以帮助节省能源。分析本段结构和大意可以看出，空后的this指代的应是空处出现的内容，且与节能做法有关。 7．选A　空后提到了用卷起的毛巾、双层玻璃窗和厚重的窗帘等物品来阻止热量逸出，A项“温暖的空气可以很容易地从房间逸出”提出了家居里存在的问题，与后面的解决办法相呼应。 8．选G　本段主要讲了可以在家里做很多其他的小事情来节省能源，如烹饪时盖上锅盖，烧开水时不要将容器装得太满，不要让电器处于待机状态。 9．选C　空前提到因此，我们被鼓励更加有效利用燃料，空后是我们需要这样做来减少碳足迹，这样能源使用就不会以破坏地球为代价。由此可知，空处应起到过渡作用，将节能从减少日常开支引到环境保护，故选C项“但我们的主要目标并不仅仅是省钱”。 Ⅲ.完形填空 (2024·扬州中学高三月考)I was in about 40 feet of water. I knew I should not have gone 10 ， but I believed I was very experienced and just took a chance. There were not many currents, and the water was so warm and clear.
