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:
- Cần đọc kỹ hướng dẫn sử dụng vắc xin trước khi dùng, nếu không rõ thì hỏi thêm ý kiến của bác sĩ thú y.
- Khi dùng phải kiểm tra lọ vắc xin bằng mắt thường xem màu sắc, độ vẩn có gì khác thường (ví dụ: không dùng vắc xin bị đổi màu, vẩn đục).
- Không được tiêm vắc xin cho động vật đang mắc bệnh, nghi mắc bệnh, động vật quá gầy yếu, quá non, con mẹ mới đẻ, động vật mới thiến chưa lành vết thương, những con mang thai ở kỳ cuối.
- Dùng vắc xin đúng liều lượng, đúng vị trí, đúng lứa tuổi.
- Xi lanh, kim tiêm phải đảm bảo tiệt trùng. Biện pháp tốt nhất là luộc sôi hoặc hấp, để nguội dụng cụ trước khi sử dụng (chú ý không nên dùng cồn để sát trùng dụng cụ).
- 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.
3. Một số bệnh cần chú ý tiêm phòng cho vật nuôi
- Đối với trâu bò: tiêm phòng bệnh tụ huyết trùng, lở mồm long móng.
- Đối với lợn: cần được tiêm phòng đầy đủ 04 bệnh đỏ (tụ huyết trùng, phó thương hàn, đóng dấu lợn, dịch tả lợn), lở mồm long móng.
- Đối với đàn gà: tiêm vắc xin Newcastle, Gumboro, Cúm gia cầm.
- Đối với đàn thủy cầm: tiêm Cúm gia cầm, Dịch tả vịt.

Nowaday,teenagers mostly have their own smartphones.Using smartphone is not bad because you can search informations,study or relax.But,bring them to schools is not nice.It is not safe for you.Why?Firstly,if you bring an expensive one,you might be robbed and the school you're studying won't have the responsibility of this.Secondly,if you are running,you may fall and break it.Thirdly,you will be scold when you lend your phone to your friend without any good purpose.Not only that,you may use your phone in class and that will affect the other classmates.So,I say that bringing your phone without purpose is not good,but bringing it to call your parents to take you home is still alright.

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.
Rubbish is a problem of environment nowadays. Many unconscious people throw a lot of rubbish away everyday. The rivers now are polluted, the air isn't as fresh as in the past and the animals die more and more. So, we have to reduce the amount of waste. But how? We shouldn't throw things away, we can reuse them. For example, we can use leftover food to make fertilize. We should only buy what things we really need. And when we go shopping, we should use cloth bags instead of plastic bag. Because of the Earth, we have to reduce the amount of waste.

Over time we live and develop, each of us will choose a unique habit. My friends have a habit of playing games on the weekends. Personally, I have a habit of reading in my free time every day. This habit of mine is formed from the shape of my hobby. Since childhood I have enjoyed reading. The types of books that I often read are books about life, manners, and economics. Ever since I could read, I have always enjoyed reading. However, when I was a kid, the kind of books I read were usually comic books. Currently, studying time is quite busy so I don’t have a fixed time for reading. However, whenever I have time I will read. I usually carry a book that I am half-reading in my bag. This ensures I can read ns anywhere and at any suitable time. I think the habit of reading has helped me improve myself a lot. In the future I will keep this useful habit. If you are free, you can practice reading habits like me.

Some people say that they like living in the countryside, the others like living in the city. In my point of view, I prefer living in the countryside for a number of benefits. First of all , It is a quiet and peaceful place. There are a lot of plant species so the air and the food are fresh and clean. We can enjoy a healthy natural condition without worrying much about environmental pollution. We are free to admire the breathtaking landscapes such as huge meadows, peaceful hills or forests. We can also enjoy walking in the forest and picking mushrooms or hunting. Second, There aren't any huge blocks of flats, modern skyscrapers and bothersome traffic jams in the countryside so the air is not polluted. There is no water pollution, either. Moreover, living in the countryside is cheaper than it is in the city, so you can buy many hings at lower prices. The other positive side is the safety. In the rural area the crime rate is much lower. There aren't a lot of housebreaks of burglary and robbery. In the countryside people usually and keep eyes on neighbour's estates. They always react when something strange is happening. Finally, most of the villagers are friendly and hospitable. They are always willing to help each other. Moreover, people in the cities are very susceptible to stress because of pollution, the pressure of work, competitions, etc. In summary, Living in the countryside has many advantages because of fresh air, clean food, specially the people’s friendliness and hospitality.
