Online shopping is buying a product or service over the internet.
Online shopping is easy. You visit a seller's website, select the product you want to buy, and order it. You can pay online or when you get the product. Online shopping is convenient. With Internet access, you can purchase anything, at anytime from anywhere. It could be a meal, a gift for a friend, or even an English course. You can save the trouble of travelling, time, and money (mở rộng ý để giải thích cho từng lợi ích của nó).
However, shopping online has disadvantages, too. Firstly, the products you receive are sometimes not exactly what you expect. Secondly, when you are not happy with a product, you can return it, but you have to pay for the shipping. Thirdly, you can easily become a shopaholic because it is easy and there are many products to choose from. You may find it hard to stop yourself from over-shopping. You may even buy things you don't really need. (mở rộng ý để giải thích cho từng bất lợi của nó)

Unit 9 : Natural Disasters.
Flood is one of the most dangerous natural disasters. It usually happens due to heavy rainfall and occurs most often in central Vietnam and coastal areas. It causes a lot of damage to people and property.
First, killing people, livestock and poultry by the flood. Second, crop loss due to flooding. Humans become homeless ( mở rộng ý về hậu quả của nó ).
So what should people do before, during, and after it happens? Before flood happens, we should prepare an emergency kit (kể tên ra emergency kit gồm những gì). Also, listen to the local warning and information about the flood on the TV or radio. During a flood, stay inside a safe and high place, follow instructions from local authority. After a flood, avoid moving water. Return home only when authorities indicate it is safe.
UNIT 10 : COMMUNICATION IN THE FUTURE.
In the future, many new means of communication will be used. One of them will be telepathy. We will use a tiny device to pass our thoughts to each other without talking. It has a lot of advantages. Firstly, we can communicate with other beings such as animals or plants. Secondly, we can communicate in all situations where written and verbal are not possible. Besides that, telepathy also has disadvantages. Some people can read one's mind to control someone else. Moreover, some people can be lazy to talk anymore.
