Dead Chicken Resently, people can hardly buy a live chicken in Chinese market due to the serious bird flu which can spread easily in the days before summer comming. There are many kinds of bird flu virus, such as H5N1、H7N1、H7N2、H7N3、H7N7、H9N2 and H7N9, among them H5N1 and H7N9 are the two of the most dangerous for humans and unfortunately these two virus had caused death. The goverment had taken steps to prevent people from these threatening virus, since live chickens started to decrease and will be dispeared in the Chinese market at the end. However, maybe we can kill the all chickens in the markets, but we can not kill the all birds fly in the vast sky too. Only by producing the relative vaccine can stop these dangerous virus threating us. So I think we should pay more attention to solve the problem rather than simply protect from these virus.

i am in a Lab I work in lab every day and do some chemical experiments. Sometimes i will bored about my research because of many failures. But everytime i was inpatient with my research, i always reminded myself to calm down and have a break. It really help me to analyse my problems rationally, therefore i can continue my work again with a peaceful mindset.
