chlorophyll captures sunlight.The glucose produced is used by the plant for energy,and oxygen is released into the atmosphere.2.Renewable energy sources are those that can be replenished naturally and are sustainable over the long term,such as solar,wind,and hydro power.Non-renewable energy sources,such as coal,oil,and natural gas,are finite and will eventually be depleted.Renewable energy sources are generally considered more environmentally friendly because they produce fewer greenhouse gases and pollutants.3.Water is essential for the human body as it makes up about 60%of our body weight.It is involved in numerous bodily functions,including regulating body temperature,transporting nutrients and oxygen to cells,flushing out waste products,and lubricating joints.Without adequate water intake,these functions can be impaired,leading to dehydration and various health issues.4.A healthy diet should include a balance of macronutrients(carbohydrates,proteins,and fats),micronutrients(vitamins and minerals),and fiber.It should also be low in processed foods,added sugars,and unhealthy fats.A healthy diet helps maintain a healthy weight,reduces the risk of chronic diseases,and supports overall well-being.五、讨论题1.Technology has significantly impacted education by providing access to a vast amount of information through the internet,enabling distance learning,and offering interactive tools that enhance the learning experience.However,it also poses challenges such as the potential for distraction,the digital divide,and the need for proper technology integration in the classroom.2.Environmental conservation is crucial for preserving natural resources,protecting biodiversity,and mitigating the effects of climate change.It involves practices such as reducing waste,conserving water,using renewable energy,and protecting endangered species.Environmental conservation helps ensure a sustainable future for generations to come.3.The internet has revolutionized modern society by providing instant access to information,facilitating communication and collaboration,and enabling e-commerce and online services.While it has numerous benefits,it also raises concerns about privacy,security,and the spread of misinformation.4.Living in a big city has both benefits and drawbacks.Benefits include access to a wide range of job opportunities,cultural activities,and便利amenities.However,drawbacks include high living costs,traffic congestion,pollution,and a faster pace of life that can be stressful.
