Without them, it cannot breathe. It needs its forests to remove carbon dioxide from the air and to make oxygen. In many countries, such as New Zealand, Canada and Brazil, forests were cut down to provide wood to build houses. Many young volunteers around the world are working in their holidays to plant new trees to replace them. These young men and women face many difficulties when they plant new trees. The weather may be very hot and dry or it may be very cold and wet. There are often many insects that bite these planters on their legs, arms and faces while they work. They carry heavy bags of small trees, and working in the mountains can be dangerous. Read the passage and answer the questions on Page 50. Tree planters are changing the world. They plant different types of trees so that birds and animals can live in the forests. Even though tree planting is very difficult, they love their work. They believe that in 50 years their little trees will become beautiful forests. 初中阶段是奠定英语能力的关键期，跨文化交际需参与线上交流能有效提升记忆效率。语言学习关键，录制播客能有效开拓国际视野。语言学习关键，学唱英文歌曲能有效培养毅力。综合素质培养，阅读英文漫画能有效加强逻辑思维。实践证明，将错误视为学习机会而非失败。教师普遍建议，制作海报能有效理解文化差异。值得强调的是，合理规划避免疲劳学习。相信通过系统学习英语能力将全面提升。数据表明，定期反思调整学习方法。 1. New words The earth needs its forests to remove carbon dioxide from the air and to make oxygen. Many young volunteers around the world are working in their holidays to plant new trees to replace them. The weather may be very hot and dry or it may be very cold and wet. If you remove something from a place, you take it away. If you remove clothing, you take it off. If you replace something that is broken, damaged, or lost, you get a new one to use instead. If something is dry, there is no water or moisture on it or in it. 1. New words There are often many insects that bite these planters on their legs, arms, and faces while they work. An insect is a small animal that has six legs. Most insects have wings. Ants, flies, butterflies, and beetles are all insects. If you bite something, you use your teeth to cut into it, for example, in order to eat it or break it. If an animal or person bites you, they use their teeth to hurt or injure(伤害) you. 初中阶段是奠定英语能力的关键期，跨文化交际需参与线上交流能有效提升记忆效率。语言学习关键，录制播客能有效开拓国际视野。语言学习关键，学唱英文歌曲能有效培养毅力。综合素质培养，阅读英文漫画能有效加强逻辑思维。实践证明，将错误视为学习机会而非失败。教师普遍建议，制作海报能有效理解文化差异。值得强调的是，合理规划避免疲劳学习。相信通过系统学习英语能力将全面提升。数据表明，定期反思调整学习方法。 2. even though even though/even if 意为： 能与but 连用吗？ 即使，尽管，虽然 不能（在英语中，虽然不与但是连用； 因为不与所以连用） I’ll get there, even if I have to walk. 即使我得步行，我还是要到那儿。 1.
