The main source of energy at present is fossil fuel.

Some alternative sources of energy are wave energy, solar energy, biofuels, natural gas, geothermal power, wind energy, biomass energy, tidal energy, hydrogen gas, etc.

Their advantages are that they are renewable and is most likely to never run out. Also, they are easier to find than fossil fuels. They produce little or no waste that is harmful to the environment like carbon dioxide or methane so they are more environmentally friendly. Their disadvantages are that they don't produce as much energy/electricity as fossil fuels. Another disadvantage is that they rely on their surrounding. For example, wind energy needs to be generated at a windy location and needs wind turbines that take up a lot of space or solar energy needs to be generated at a sunny area and needs lots of solar panels.

5. Talk about your favourite sport

I would like to talk about a sport that I particularly enjoy and have been practising for a few years. It is basketball. For me, this is not only a sport or a physical exercise but also an ideal way for me to relieve of stress and to make new friends.

I first knew about basketball when I was a little kid through a video game called NBA 2k8. However, at that time I did not play badminton at all, partly because I was not an active kid who was aware of the critical importance of physical exercises. When I went to high school, a lot of my friends were a big fan of basketball and my high school offered big playgrounds for sports activities, therefore I practised basketball much more often.

I usually play basketball in the weekends and watch NBA on the nights when my favorite team, the Los Angeles Lakers play. I often go to sports centres with a number of my classmates for basketball matches. Sometimes we even participate in local league, didn’t accomplish anything big but it was extremely fun.

For me, basketball is a good way to help me pursue a healthy lifestyle. It is also an affordable type of sport as you do not have to buy a lot of specialised sports materials. Finally, playing basketball enables me to develop a number of important and non-academic skills such as discipline, team-work, problem-solving and co-operation.

             THE ADVANTAGES AND DISADVANTAGES OF SMART CITIES

     Smart cities are built on new technologies to improve people's lives. The idea of living in one of them sounds very exciting. But is a life controlled by smart technologies good or bad for us?

     Let’s start with the advantages. One of the biggest advantages of smart cities is the high level of convenience they offer. With smart technologies in place, people can access information and services quickly and easily. This makes daily life more efficient and saves people a lot of time. Additionally, smart cities are designed to be more sustainable, with green spaces and public transport options to reduce pollution.

     What about the disadvantages? One of the main concerns people have about smart cities is the potential loss of privacy. With sensors and cameras constantly monitoring people's movements, there is a risk that sensitive information could be collected and shared. This can lead to a lack of trust and a feeling of being constantly watched. Furthermore, there are concerns about the potential for technology failures and the risks posed by hackers.

     In conclusion, there are both advantages and disadvantages of living in a smart city. In my opinion, the benefits of smart technologies outweigh the drawbacks. However, it is important that measures are put in place to protect people's privacy and ensure the safety of their personal information. As long as these concerns are addressed, smart cities have the potential to revolutionize the way we live and work.

       AI (Artificial Intelligence), is artificial intelligence, is intelligence demonstrated by machines, as opposed to natural human intelligence, which is commonly used to describe machines. AI is a great achievement of modern science, if you know how to apply it, it will bring a lot of benefits to you such as it can detect and limit risks, help people predict risks. of all mankind such as epidemics, natural disasters,... Next, AI was born to help people save more and more labor because of its high automation ability. Thanks to AI, humans can reduce labor in operating the line. There is also a language bridge, unleashing creativity,... It also helps us to create texts from words. self-synthesizing computer data, converting human speech into a form that can be understood by computer applications, providing data as well as computing technologies. The positive change that AI can bring, but there is also considerable anxiety surrounding the technology. As AI continues to become more advanced, the repetitive jobs of bankers are likely to be completely replaced by artificial intelligence. Therefore, it is very important to increase the benefits that outweigh the risks of artificial intelligence to life.

Nowadays, many thousands of A.I. applications are so popular that they are not even thought of as being A.I. anymore. However, it has been noted that there are both advantages and disadvantages to relying on these intelligent machines.
Automated machinery is efficient in manufacturing and makes retail easier. Many large factories use fully automated systems that receive raw materials at the start of a production line and output a packaged product at the end. Machines can also load trucks with the packaged products for delivery to customers. In addition to its applications in manufacturing, automated machinery can also be used to save lives and help people to heal. For example, in the hospital, an automated breathing machine can help a patient to breathe, an automated dialysis machine can clean a kidney patient’s blood, and an automated X-ray machine can provide reliable X-ray images for the doctor to use in discovering the exact cause of an illness.
However advantageous, one of the great disadvantages of automated machinery is the potential loss of information or even human lives. The production line in a factory, or the treatment process of a patient, can be interrupted if a power failure happens. Moreover, automated machines or robots could fail to work properly if they were damaged or hacked by wrongdoers. If a military drone was hacked or malfunctioned, innocent people could be hurt or killed.
Taking everything into consideration, the advantages of using automated machines outweigh their disadvantages. With the advances in technologies occurring now and in the future, there is the very real potential for a better world and human life extension.

Read the passage and check (ü) whether the following statements are true (T) or false (F).

Energy makes change; it does things for us. It moves cars along the road and boats over the water. It bakes a cake in the oven and keeps ice frozen in the freezer. It plays our favourite songs on the radio and lights our homes. Energy makes our bodies grow and allows our minds to think. Scientists define energy as the ability to do work. People have learned how to change energy from one from one form to another so that we can do work more easily and live more comfortably.

All forms of energy are stored in different ways, in the energy sources that we use every day. These sources are divided into two groups – renewable and nonrenewable. Renewable energy source is an energy source that can be replenished in a short period of time. Nonrenewable energy source is an energy source that we are using up and cannot recreate in a short period of time.

Renewable energy sources include solar energy, which comes from the Sun and can be turned into electricity and heat. Wind, geothermal energy from inside the Earth, biomass from plants, and hydropower and ocean energy from water are also renewable energy sources.

However, we get most of our energy from nonrenewable energy sources, which include the fossil fuels – oil, natural gas, and coal. They’re called fossil fuels because they were formed over millions and millions of years by the action of heat from the Earth’s core and pressure from rock and soil on the remains of dead plants and animals. Another nonrenewable energy source is the element uranium, whose atoms we split (through a process called nuclear fission) to create heat and ultimately electricity.

Question: Most of our energy we use every day comes from renewable energy sources.

A. True

B. False
