In the world there are many types of energy sources,but today, the one I will tell you is the wind energy. It is a renewable energy source, so it has many advantages. Firstly, it is not harmful to the environment, people will not need to worry about environmental problems when using it. Second, wind energy lasts forever, and like tidal or solar energy, we will never run out of it. Third, it is cost effective. There are no costs associated with buying or transporting fuel into wind turbines, like coal-fired power plants. In addition, with advancements in technology, wind energy will become cheaper, thereby reducing the amount of capital that countries have to spend to meet their energy needs. However, it also has disadvantages. Windmills will make noise for everyone nearby, causing noise pollution. Not only that, the animals around it can also be in danger. Are birds safe to crash into windmill wings? Despite the downsides, the advantages of wind power are also great. It would be great if we humans use it in the future.

Cho mk hỏi advantages và disadvantages đúng ko

1. They are convenient.

It’s great being able to call a friend when you are out and about – without being tied to a land line.

2. They can be life savers.

Taking a mobile phone with you when you go hiking is a basic safety precaution. If you lose your way or get stuck in bad weather, your mobile phone could just save your life.

1. Dependency

It is easier than you might think to become addicted to your mobile phone, and so dependent on it that you forget to communicate in real life.

. Isolation

It’s ironic, but some people feel that the cellphone (which is designed to keep people connected) can actually drive us further apart. Have you ever seen a group of friends at a restaurant, looking down at their phones instead of each other? That.

6. Security issues

If someone taps in to your data they could steal your identity, pilfer your photos, and erase your contacts list.

I think there are both advantages and disadvantages of online calls. Internet calls are cheap or even free. Many social networks provide free calls for people to communicate. Online calls help us to communicate with people that are really far away from us, for example, our relatives or our Internet friends. Moreover, you can create group calls when you are in need of hosting a conference or a family meeting. However, online calls also have drawbacks. You can’t make online calls unless you have Internet connection. Also, you need a smart device to perform a call. Sometimes, you may get unwanted calls from the person you don’t know.

Mình nghĩ là có cả ưu điểm và nhược điểm của cuộc gọi trực tuyến. Cuộc gọi trên Internet rẻ hay thậm chí là miễn phí. Có nhiều mạng xã hội cung cấp các cuộc gọi miễn phí để mọi người có thể giao tiếp. Những cuộc gọi trực tiếp giúp người ta giao tiếp với những người ở rất xa, ví dụ như họ hàng hay bạn bè qua mạng. Hơn nữa, bạn có thể tạo những cuộc gọi nhóm khi bạn cần tổ chức cuộc họp hay họp gia đình. Tuy nhiên, những cuộc gọi trực tuyến cũng có những hạn chế. Bạn không thể thực hiện cuộc gọi trực tuyến nếu không có kết nối mạng. Hơn nữa bạn cũng cần một thiết bị thông minh để gọi điện. Đôi khi bạn có thể nhận những cuộc gọi không mong muốn từ những người bạn không biết.

- I’ve bought bluetooth headphones recently. It’s very convenient to listen anytime, anywhere. The biggest disadvantage is that the ear buds can get lost way more easily than wired models.

- I’ve bought a smartwatch recently. I found it really easy to check notifications, track our fitness goals, and make phone calls directly from the wrist. My only problem was that battery life could be better. I had to recharge the watch daily, which can be inconvenient at times.
