làm từ thiện mà có tác hại hả?

For a long time, television has been regarded as a saving means of entertainment and acquiring useful knowledge. However, besides the benefits mentioned above, it also brings a lot of harm because of the following reasons. First, watching TV takes up a lot of our time. I do not deny the benefits such as entertainment or education that it brings. However, instead of spending all the day just watching TV, we can do some useful works such as doing homework, helping mother to do housework. Through that, we can gather for ourselves a lot of soft skills and become closer to the other. Second, sitting too close to the TV screen will make harm affect on our health. Studies have shown that sitting near television will shorten our vision, in addition increase the risk of cardiovascular diseases and degeneration of the neck vertebrae ... These are the disadvantages that no one expects. Therefore, let's limit the amount of time spending watching TV and save that time doing other useful things.

Modern society is constantly developing, and the appearance of the Internet has opened up a whole new era of access and sharing of information. This brings a tremendous reform and benefits to all humanity. In our lives there are innumerable questions that need to be answered, and the Internet was born as a useful tool to help us solve those questions. Searching for information in the past has cost humanity a lot of time and effort, and not everyone had patience to turn the pages one by one to find the information they needed. However, our lives have changed tremendously since the arrival of the Internet, and the search of general information on the Internet has not consumed us much more than mouse clicks and keyboard typing. This is where most basic and specialist information is gathered from the majority of occupations and fields in our life. There are countless websites that contain useful information for research and study, and Wikipedia is now considered to be the most complete and accurate encyclopedia. Searching the Internet is simple, but we should also be careful in getting that information. Not all knowledge on the Internet is accurate and complete, so we need to compare information from many different sources before actually using any of them for our purposes. The Internet is an infinite ocean of knowledge, and we can learn countless things if we know how to use it properly.

    The world is currently very developed, which means that technology is very evolving, especially smartphone. And it brings a lot of benefits, I of course agree. Because it's so useful. Smartphone works remotely, even when you're in another part of the world. You can communicate verbally, video, audio and exchange other media. All websites, applications and software have been created to help users socialize. Social media, texting, texting, laptops, tablets, and cell phones mean no one needs to feel isolated in the digital world. Users can be regularly updated with news about local events and social developments. We can also learn through technology. Anyone with access to the internet today can access a huge amount of the world's knowledge through the web. Alternatively, lessons and courses can now be offered virtually online. Online social media or playing computer and mobile games is becoming more and more popular. Traditional media also developed, as television and broadcasting were digitized along with radio. It has many benefits, but it also has harmful effects. Nowadays, there are a lot of young people who are interacting too much with internet devices, and can easily watch bad programs, programs like those are not good for them.

1. Bảo quản vắc xin

Đây là một yếu tố đặt lên hàng đầu bởi vắc xin luôn đòi hỏi phải bảo quản ở một điều kiện nghiêm ngặt, đặc biệt là các loại vắc xin nhược độc. Mỗi loại vắc xin đều có một khoảng nhiệt độ bảo quản thích hợp, đối với các loại vắc xin virus ở nhiệt độ từ 2 – 8°C, các loại vắc xin vi khuẩn từ 5 – 150C. Nếu nhiệt độ bảo quản vắc-xin nằm ngoài khoảng nhiệt độ bảo quản, hoặc để vắc xin bảo quản ở ngăn đá sẽ làm mất tác dụng của vắc xin.

Ngoài ra, bà con cũng cần chú ý việc bảo quản vắc xin khi vận chuyển, nếu ở xa nơi bán vắc xin thì khi đi mua nhất thiết có hộp xốp, phích đá để bảo quản; nếu mua gần thì bảo quản bằng túi nilông tối màu có giấy bọc. Khi vận chuyển vắc xin cần bao gói kỹ, tránh hiện tượng va đập, tránh được vắc xin tiếp xúc trực tiếp với đá lạnh, đặc biệt không cho ánh nắng trực tiếp chiếu vào vắc xin để đảm bảo chất lượng và hiệu quả phòng bệnh của vắc xin.

2. Sử dụng vắc xin

Nếu khâu bảo quản tốt song chúng ta sử dụng vắc xin không đúng kỹ thuật thì hiệu quả cũng sẽ thấp. Khi sử dụng vắc xin chúng ta cần chú ý các yếu tố sau:

- Pha vắc xin đúng chỉ dẫn, trước khi sử dụng phải lắc kỹ lọ vắc xin.

- Vắc xin pha xong dùng ngay, không để quá 2-3 giờ sau khi pha, không cầm lâu trong tay; nếu thừa phải hủy, không được dùng cho ngày hôm sau; không vứt bừa bãi chai lọ, kim tiêm.

- Sau khi tiêm vắc xin, cần theo dõi vật nuôi để kịp thời phát hiện các trường hợp gia súc, gia cầm phản ứng sau khi tiêm để có biện pháp can thiệp.

In my daily life, I have some hobbies such as traveling, cooking, listening to music, etc. However, I enjoy reading books most. To me, books are always a good friend. Firstly, reading books makes me feel relaxed after many long stressful hours at school. I really like comic books because they contain many colorful and interesting images that keep my spirit relaxed. Secondly, reading books is a good way to improve my vocabulary and grammar. For example, reading books tells me about the world’s history, lets me see the structure of the human body, or brings me a story of Harry Potter. In conclusion, I think reading is one of the most interesting indoor activities.

Currently English is very common in Vietnam. It helps us in communication as well as learn the language of England. Not only learning, listening and writing, but now we can rely on is the book to learn more words. Reading will help us to better understanding and use of the correct and reasonably so. Also, if we know how to read, it will be beneficial for us to read and understand it as well. Do not despise reading, do not think that reading is not and does not help then you are wrong, it helps to be much like to study later on you will not be shy in communicating with them and will also not ashamed of talking.

The book is written in the language system, namely the written word constantly linked together to form sentences, lines, paragraphs, all ... The word is used always meant, and means that the definition is referred to the corresponding things in life. Examples mentioned 'still life' we think of a variety of utensils or fruit is placed in a state of calm, said to 'orbit' we think of a set of points that make up a closed path for for the movement of a certain entity, or mention 'Leopard' we think of many wings flowers, blooming in the spring, beautiful, and people like to enjoy ... Thus, the process is essentially reading is a process of observing things and phenomena in real life, but writing was conventional process through symbolic imagination, think.

Then when the association also arise when you compare the problems have been reading in this book and other books, in the opinion of this person others, the same or different, why is there such similarities and differences ... imagination rich, deep thinking, combined with the quest to discover the motivation will help you formulate creative energy, think of something new, find new ones and thereby make new ones.
