Answer 2

Answer:

Probably the first word that comes to your mind is “disease”. Indeed, many terrible diseases such as plague, cholera, and anthrax have their inseparable cause in bacteria. However, you may not be aware that not all bacteria have fierce faces, sharp claws, and a malicious nature. Many bacteria are “gentle and lovely”. In addition, under certain circumstances, those malicious bacteria can become our “intimate ally” after being reformed by scientists. They can be the crucial weapons for us to defeat disease and protect health. Still many bacteria make great contributions to industry, agriculture, and environmental protection. There are two sides to bacteria. When they are positioned in the proper place, they can be our friend; once they walk in the wrong place, they become our enemy. Therefore, bacteria are both our friend and our foe
