Global warming is a pressing issue that has garnered widespread attention in recent years. The Earth's temperature is rising due to the accumulation of greenhouse gases, primarily carbon dioxide, in the atmosphere. This phenomenon is largely attributed to human activities such as burning fossil fuels and deforestation. The consequences of global warming are far-reaching, affecting ecosystems, weather patterns, and sea levels. Urgent global efforts are needed to mitigate these impacts, transition to sustainable practices, and raise awareness about the importance of environmental conservation. Addressing global warming requires collective action to ensure a sustainable and habitable future for generations to come.

Living in a smart city offers a myriad of benefits that significantly enhance the quality of life. The integration of advanced technologies in urban infrastructure fosters efficiency and sustainability. Smart cities leverage data analytics and the Internet of Things (IoT) to optimize various aspects of daily living, from traffic management to waste disposal. This results in reduced congestion, lower pollution levels, and improved overall environmental sustainability. Additionally, smart cities often boast enhanced public services, such as efficient public transportation systems and responsive emergency services. Residents can enjoy the convenience of connected technologies, including smart homes and digital services, contributing to a more streamlined and interconnected community. Ultimately, the smart city concept not only enhances urban living but also promises a more sustainable, efficient, and enjoyable lifestyle for its inhabitants.

In today's digitally-driven society, teenagers have become increasingly connected to screens, be it laptops, phones, or tablets. While technology offers numerous benefits, excessive screen time can have detrimental effects on teenagers' physical and mental well-being. Therefore, it is crucial to limit their screen time.Firstly, excessive screen time can lead to sedentary lifestyles and a lack of physical activity. This can contribute to obesity and other health problems. Additionally, extended screen time can negatively impact teenagers' sleep patterns, leading to sleep deprivation and fatigue. It also hampers their ability to concentrate and engage in face-to-face social interactions.Limiting teenagers' screen time can be achieved by setting clear boundaries and establishing screen-free zones or times during the day. Encouraging alternative activities, such as participating in sports, hobbies, or spending time with family and friends, is also important. Furthermore, parents should act as role models by reducing their own screen time.In conclusion, while screens have become an integral part of teenagers' lives, excessive usage can have adverse effects. By implementing strategies to limit screen time, we can promote their physical health, mental well-being, and overall development.

Limiting teenagers' screen time is essential for their physical and mental well-being. Excessive use of electronic devices can lead to sedentary lifestyles, contributing to health issues such as obesity and poor posture. Additionally, prolonged screen exposure can negatively impact sleep patterns, affecting teenagers' overall health and academic performance. By setting limits on screen time, parents can encourage a more balanced and active lifestyle, fostering healthier habits. Moreover, reduced screen time allows teenagers to engage in face-to-face social interactions, developing crucial communication skills. It also provides them with opportunities for outdoor activities and creative pursuits, promoting a more holistic approach to personal growth. In essence, imposing reasonable restrictions on screen time is a proactive measure to safeguard teenagers' health, social skills, and overall development in the digital age.

The human body is a symphony of intricate rhythms, orchestrated (34) _____ an invisible conductor known as the body clock. It is the mastermind behind our sleep-wake (35) _____, regulating our internal processes with unwavering precision. Like a skilled maestro, it synchronises our biological functions, guiding us through the ebb and flow of each day.

This internal timekeeper, also (36) _____ as the circadian rhythm, governs our sleep patterns, hormone production, and metabolism. It dances to the beat of external cues, such as sunlight and darkness, aligning our bodies with the (37) _____ rhythms of the world around us. But this remarkable clock isn't just a mechanical timepiece. It has the power to shape our physical and mental well-being. When in harmony, it bestows us with vitality, alertness, and a sense of balance. However, (38) _____ disrupted, it can unleash chaos, leading to sleep disorders, mood swings, and even compromised immune function.

Problems with fossil fuelvi. Alternative energyvii. It is a two-way processviii. Iron is the bestix. Engine power vs. clean emissionsx. Greenhouse effect and global warmingxi. The side- effect of one solutionxii Increase engine efficiency - how it works.The problem of fire Ironed OutIt has been quite a while since man discovered fire. But it is only recently that he has learnt enough chemistry to think of improving it. Take fossil fuels, suchas coal and oil, for example. They give off plenty of heat when they burn ;unfortunately, they give off plenty of other things as well, including the particlesthat make up smog and soot, the carbon dioxide responsible for the greenhouseeffect and the oxides of nitrogen and sculpture that help to made acid rain. A newfuel additive called Carbonex seems drastically to reduce emissions of particles andof nitrogen oxides. It may thus help to solve half the problems.To understand the solution, take a closer look at the problem. Fossil fuelsare mostly made of carbon, which reacts with oxygen to produce carbon dioxide (inthe case of coal) or carbon dioxide and water (on the case of petrol, diesel fuel andother refined oils). The combustion of fossil fuels is8never quite complete. Small, unburnt particles of fuel always escape, often as blacksmoke. These particles contain cancer- causing chemicals and are ever moreunpopular.There is a standard fix for this. To reduce the problem of incompleteburning, combustion chambers are routinely flooded with about 25% more air thanthey need to burn their fuel. The idea is to give the flame more oxygen and hence,increase the efficiency of burning. But there is a snag. Dry air is 21% oxygen and78% nitrogen. Nitrogen, like carbon, reacts with oxygen at high temperature—in this case producing the nitrogen oxides (NOX) that help cause aid rain. Whenextra air is added to a combustion chamber, emissions of soot and smog go downbut NOX emissions go up. Carbonex, invented by an academic chemist, Dr. DavidFarrar. At the university of Toronto, and developed by Velino Ventures of Toronto,tries to alleviate this. The active ingredient is a hydrocarbon molecule to which aniron atom is bound. The molecule acts as a carrier for the iron, letting it dissolve in. Paragraph A 2. Paragraph B Paragraph C 3. Paragraph D 4. Paragraph E 5.
