Nowadays, energy is being run out more and more so it is one of the most important things of our life. We need to save energy because nobody of us can lives without energy. So why don't we start to do it right in our home? We have many ways to save energy in our home. One of those ways is using electricity, water and gas economically. Such as we should turn off the light in room when we go out or in unnecessary situations, avoid wasting water, shut the kitchen stove when stop cooking. Use a microwave instead of a stove to reheat food. Use rechargeable batteries instead of disposable batteries... Besides, we should use electrical equipments which are energy - saving. Such as using lights and fans that have low capacity, or using equipments which reserve electricty. Not only do these help us to save money but also they work effectively.
In addition, we should frequently check electrical equipments in our home in order to fix opportunely. In summary, we need to save energy so that energy isn't run out and continues to serve human's life.

2. Write about one types of alternative source energy.

Solar, light and heat radiation from the sun, has been exploited by humans since ancient times using a growing array of technologies than ever before. Solar radiation, along with secondary resources of solar energy such as wind and wave power, water and biomass, make up most of the renewable energy available on Earth. Only a very small fraction of the available solar power is used.

Solar power means generating electricity based on heat and photovoltaic cells. The use of solar energy is limited only by human ingenuity. Partial list of solar applications space heating and cooling through solar architecture, through distillation of drinking water and sterilization, daylight illumination, solar hot water , Solar cooking, and high temperature process heat for industrial purposes. To collect solar energy, the most common way is to use solar panels.

Solar technology is widely described as either passive solar or active solar energy depending on how they capture, convert and distribute solar energy. Active solar engineering involves the use of photovoltaic panels and solar thermal power to harness the power. Passive solar engineering involves orienting a building towards the sun, selecting materials with favorable heat mass or dispersed light property, and designing natural air space.

Good morning/afternoon ladies and gentlemen,

My name is Dang. Today I’m going to tell you how to save home energy.

Most people use too much electricity and water at home. You can reduce the amount of energy by

-using short shower heads or buy ’low-flow’ showers;

-turning off the lights and air conditioners before leaving home or whenever you are not in your rooms.

-keeping the refrigerator doors closed.

-going to school by bike.

If you take my advice, you won’t have to pay so much for your bills, and you can save necessary energy.

Thanks for listening.

Nowadays, the environment of our school is getting more and more polluted, so I think we should take action to protect them. Firstly, we don't throw rubbish inside or outside classrooms. It is easy to put our wastes in dustbin instead of throwing away. Secondly, we shouldn't write or draw anything on desks or walls. I suppose that this action is not good because we are destroying the school property. Futhermore, the classrooms should be cleaned every day by not eating or making too many litters at school. Finally, we should water trees and plants at school regularly. Moreover. planting more trees help us to respiratory benefit and limit air pollution. In conclusion, these ways bring us manu benefit because it isn't only protect environment of school but only make us to become more healthy.

many people in my school lead a healthy life depends on living enviroment.Enviroment means all that surrounds us include water dirt tree,...

but the present situtation of global enviroment is pollution in my school. many students litter our the school and they have no sense of enviromental protection.And these problems have made the school worse.So that we do to protect the enviroment?we can should have all students plant trees around the yard,do not litter indiscriminately,put the rubbish in the right place. and clean up rubbish at school.We have to do this because the enviroment is very important to everyone.

Nowaday, traffic problem is the biggest problem that many people care about. In VN, I think the city where have the worst traffic is Ha noi.
The first problem is the traffic jam here. Why? In the rush hours of the day, there're too many people using the road. Last year, in 2013, many bridges was built so it happen less but in order to stop this, a kind of small car should be invented, people should go to works by buses instead of going by motorbikes...
The second one, as you know, the roads in VN is not as big and clean as the roads in the big countries. They're narrow, bumpy and some dirty so it’s really hard for the road users to drive safely. I think we should raise money to make the road in VN better and better.
But everyone knows that Vietnamese people are not respect and don’t follow the traffic rules. That’s the biggest reason for everything. They wear the helmet that not strong enough to keep they safe if the accident may happen, they ride too fast on the small roads… The traffic will never can be improve if they keep doing this.
At the end, I hope the traffic in VN will improve more

We use a lot of energy at home and it costs us a lot. To save energy, we should use low energy light bulbs in our house. It will help us to reduce our electricity bill. Secondly, before going to bed, we should turn off electrical appliances when not using them. Finally, we should turn off the lights in room when we go out, avoid wasting water, shut the kitchen stove when stop cooking. 

Tạm dịch:

Chúng ta sử dụng rất nhiều năng lượng ở nhà và chúng ta tốn rất nhiều năng lượng. Để tiết kiệm năng lượng, chúng ta nên sử dụng bóng đèn năng lượng thấp trong ngôi nhà của mình. Nó sẽ giúp chúng tôi giảm hóa đơn tiền điện. Thứ hai, trước khi đi ngủ, chúng ta nên tắt các thiết bị điện khi không sử dụng. Cuối cùng, chúng ta nên tắt đèn trong phòng khi ra ngoài, tránh lãng phí nước, tắt bếp khi ngừng nấu.

My house primarily relies on electricity and gas for energy. Electricity powers most appliances and lighting, offering convenience but contributing to high consumption. Gas fuels the heating system, providing warmth efficiently but releasing emissions. To save energy, I've adopted simple habits: switching to LED bulbs, unplugging devices not in use, and using energy-efficient appliances. I've also improved insulation and sealed drafts to minimize heat loss. Moreover, I'm conscious of water usage, opting for efficient fixtures and practicing conservation. These steps not only save energy but also reduce environmental impact, aligning with my commitment to sustainability.

Hello everyone, today I'd like to tell you some information about types and sources of energy. Energy is classified into two main groups: renewable and non-renewable.

The energy generated from natural sources such as the sun, wind, rain, and tides is called renewable energy. They are plentiful and can be generated again and again. They also have low carbon emissions so they are considered green and environment-friendly. Moreover, using renewable energy can reduce your electricity bills. Unfortunately, solar energy can be only used during the daytime but not during night or the rainy season. Geothermal energy also can bring toxic chemicals beneath the earth's surface to the top and can create environmental changes.

Non-renewable energy is the energy taken from other sources that are available on earth.They are limited and will run out in the future. They can't be re-generated in a short time.Fossil fuels - natural gas, oil and coal - are examples of them. They are cheap and easy to use. However, when burnt, they release toxic gases in the air so they cause serious environmental changes such as global warming. And the important thing is that non-renewable sources will expire someday.

My best friend classmate is Nga. The first reason why I like her most is her nice appearance. She has long black hair and beautiful eyes. She is tall and thin enough to participate in VN nexttop model. Not only does she have a pretty appearance but she also has good characteristics. When I feel sad, nervous or stressful, she is always by my side and encourage me to overcome difficult challenges in my life. I'M so grateful for it. Moreover, she once said that:" If oneday you feel like crying, call me..I don't promise that i will make you laugh..but i can cry with you" In addition to that, we have unforgetable experience. In 1997, I was drowning when she appeared and secured me from the Death and since then, we has become closed fiends. We share a lot of things such as dreas, jobs, hobbies,.. I strongly believe that our relationship is lasting forever.
