2. Health Health is a dynamic condition resulting from a body's constant adjustment and adaptation in response to stresses and changes in the environment for maintaining an inner equilibrium. Becoming healthy is a process that involves time, commitment, and effort. Although it’s important to pay attention to the health of our bodies, we should not overlook the health of our mental and emotional states and social relationships, all of which factor in to a well-rounded approach to healthy living. With dedicated effort, you can take steps toward a healthier body, emotional outlook, and social life.

3. Health When we are talking about health, it is not just only a healthy body but also a sound mental health. A good health can be described as the condition where both our bodies as well as our mind are functioning properly. The main causes behind poor health conditions are diseases, improper diet, injury, mental stress, lack of hygiene, unhealthy lifestyle, etc. Over the past few years, our lifestyle has changed and we often tend to ignore the importance of healthy living in one way or the other.

38. Prefixes and Suffixes Prefixes A prefix is a group of letters placed before the root of a word. For example, the word "unhappy" consists of the prefix "un-" [which means "not"] combined with the root (stem) word "happy"; the word "unhappy" means "not happy." A basic word to which affixes (prefixes and suffixes) are added is called a root word because it forms the basis of a new word. The root word is also a word in its own right. For example, the word happy consists of the word happy and the suffix –ly, so it becomes happily. Some of the most common prefixes are listed below.

45. Language Focus Tenses A verb-based method is used to indicate the time, and sometimes the continuation or completeness, of an action or state in relation to the time of speaking. In this unit will state about Simple Past and Present Perfect Simple. We use the past simple for past events or actions which have no connection to the present. We use the present perfect for actions which started in the past and are still happening now or for finished actions which have a connection to the present.

For example: "She wet her hair before washing it" - British English "She wetted her hair before washing it" - American English "All the shoes fit in to the shelves" - British English "All the shoes fitted in to the shelves" - American English n British English, many past simple verbs can end with 'ed' or with 't', but in American English the ending of 'ed' is normally preferred.
