- The use of energy sources may be leads to air pollution, climate change, water pollution, thermal pollution,... But in my city, people use energy properly everyday so we haven't seen any problems yet.

- I think we can save energy by using fewer household electrical appliances, use energy economically, turn off all lights, fans, air conditioner when not use, etc.

Question 1:

In my city, there are several potential problems associated with the use of energy sources:

1. Pollution: The burning of fossil fuels for energy production can release harmful pollutants into the air, leading to air pollution and contributing to climate change. This pollution can have adverse effects on public health and the environment.

2. Resource Depletion: Dependence on finite resources like coal, oil, and natural gas for energy generation can lead to resource depletion over time. As these resources become scarcer, it may lead to price increases and economic instability.

3. Environmental Degradation: Extracting and processing fossil fuels can cause environmental degradation, such as deforestation, habitat destruction, and water pollution. This can harm ecosystems and biodiversity, disrupting natural balances.

4. Greenhouse Gas Emissions: The combustion of fossil fuels releases greenhouse gases like carbon dioxide into the atmosphere, contributing to global warming and climate change. This can lead to more frequent and severe weather events, rising sea levels, and disruptions to ecosystems and human societies.

5. Energy Inefficiency: Some energy sources, such as older power plants or outdated infrastructure, may be inefficient in converting fuel into usable energy. This inefficiency leads to wastage of resources and higher energy costs for consumers.

6. Dependency on Imports: If a city relies heavily on imported energy sources, such as oil or natural gas, it becomes vulnerable to price fluctuations and geopolitical tensions in supplier countries. Diversifying energy sources and investing in local renewable energy can help reduce this dependency.

Addressing these problems requires a shift towards cleaner and more sustainable energy sources, such as renewable energy (solar, wind, hydroelectric) and increased energy efficiency measures. Transitioning to these alternatives can mitigate environmental impacts, enhance energy security, and promote economic development.

Question 2:

In my city, there are several ways to save energy sources:

1. Saving electricity: Turn off lights, fans, and electronic devices when not in use to save electricity. Use energy-efficient LED bulbs instead of traditional incandescent bulbs.

2. Using renewable energy: Encourage the use of renewable energy sources such as solar panels and wind turbines to generate electricity. These sources are sustainable and do not deplete natural resources.

3. Using public transportation: Use public transportation such as buses or trains instead of personal vehicles to reduce fuel consumption and air pollution. Walking or biking for short distances is also a good way to save energy.

4. Conserving water: Saving water also helps save energy because energy is used to pump, treat, and heat water. Take shorter showers, fix leaks, and use water-saving devices to conserve water.

5. Insulating homes: Properly insulating homes can reduce the need for heating and cooling, saving energy. Install insulation in walls, ceilings, and floors, and use energy-efficient windows and doors to keep homes comfortable.

6. Planting trees: Trees provide shade and reduce the need for air conditioning in buildings, saving energy. Planting trees in cities helps cool the environment and improve air quality.

By implementing these measures, we can effectively save energy sources and create a more sustainable city for the future.

Here's an introduction to the Battle of Dien Bien Phu in English:

---

The Battle of Dien Bien Phu was a pivotal conflict in the First Indochina War, marking the climax of a struggle between French colonial forces and the Viet Minh, led by Uncle Ho Chi Minh. This battle took place between March and May 1954 in the Dien Bien Phu valley in northwestern Vietnam.

The French, under the command of General Christian de Castries, fortified the Dien Bien Phu valley, creating a complex series of strongpoints to defend against the expected Viet Minh assault. 

However, the Viet Minh, commanded by General Vo Nguyen Giap, executed an impressive logistical feat. They transported heavy artillery and supplies over mountainous terrain, manually hauling pieces through rugged paths. Once in position, they launched a massive and well-coordinated attack on the French positions, encircling and bombarding them with artillery, which the French had believed impossible.

The siege lasted for fifty-five days, with intense fighting characterized by trench warfare and direct assaults reminiscent of World War I battles. The Viet Minh's tactics and endurance in the face of French firepower eventually led to the fall of the French garrison.

The capture of Dien Bien Phu was a significant victory for the Viet Minh and a symbol of the rise of nationalist movements in colonial territories. It precipitated the Geneva Conference, which negotiated the ceasefire and eventually led to the withdrawal of French forces from Indochina. This battle not only marked the end of French colonial rule in Vietnam but also reshaped the geopolitical landscape of Southeast Asia.

Dien Bien Phu remains a testament to the strategic brilliance of General Giap and the resilience of the Vietnamese people. It stands as a historic reminder of the challenges of colonial warfare and the potent force of nationalist fervor.

Out of all the subjects at school, my favorite is definitely Maths, which is a natural science. To be honest, when I was a child, I was never the biggest fan of Maths, since it was too hard to understand. However, as I got older, I realized that Maths’ complexity is its charm, so I have been fascinated by it ever since.

In Maths class, we gain insights about numbers and shapes, through formulas, equations, measurements, and lots of calculations. It requires logical thinking, hard work, and good memory. Many people think that the knowledge we learn from this subject is not practical, but I personally think Maths is very applicable. For example, while building a house, I would need Geometry to figure out the best approach to lay the foundation and whatnot. And in everyday life, simple activities such as calculating my daily expenses will not be possible without Arithmetic. What I love most about Maths is the rewarding feeling after I solve a difficult problem - it is the best experience ever. 

All in all, Maths is a phenomenal subject, and is especially suitable for people keen on logic and numbers - such as myself! I simply adore it, and I am considering a career in this field.
