1. In our modern time, the computer appears in every part of our daily life. It plays an essential role at work, in education as well as in entertainment.First of all, at work, the computer helps us, in just a few hours or even seconds, type documents and do calculations, which may take a normal brain a life time to finish. Besides, with computers people can do businesses like stock transactions or design building, operate high-tech plants and run machines effectively. Then, in education, with a computer connected to the Internet we can search almost any kind information we need for our study or learn languages more effectively.  [Also, teachers or lecturers can make their lessons or lectures more lively and interesting with programs such as Powerpoint or other types of slide-show]. Lastly, for entertainment, after working hard we can get relaxed by playing some computer games or listening to our favorite type of music with the computer. When we want to see a movie, staying at home, we can search for it on the Internet just in term of minutes, without having to go to the theater or somewhere to buy videos tapes or CDs.  It goes without saying that the computer plays a key role in every part of our daily life, from businesses to education or entertainment.With it, everything in life would slow down and life would no doubt be much more dull.

2. In most of my holidays, I go to visit my family members in my hometown. For my job, I am currently residing in the capital city of my country but my parents, siblings, grandparents, uncle and aunts are living in our hometown. So in most of my holidays, I go to visit my family members. My typical holidays last for 4-5 days most of the time and sometimes I get longer holidays.

When I was a university student, I had some friends studying in the same faculty who were from my hometown. During my university study we used to go to our hometown together on our vacations but nowadays I go to my hometown mostly alone. The journey takes about 6-7 hours by bus. Sometimes we travel by train and this train journeys usually take 8-9 hours including the stoppage. Though the journey is tiresome sometimes, but the thought of meeting my family members and the excitement of being in the place I really love, wash away the tiresomeness and monotonous feeling of the journey.

The time I stay with my family members and local friends, I enjoy the moments very much. This is the town where I grew up and naturally all of my childhood & adolescence memories are related to this place. I do lots of interesting things there during my holidays: I swim in the river, take care of the garden and firm we have, collect vegetables and fruits from our garden and then make arrangement to sell those to the local sellers, sometimes I catch fished, play with my friends both indoor and outdoor games, visit different places and do lots of other stuff.  

In my city life, I have to follow a strict timeline and stay at my office most of the time, but in my hometown where I mostly go during my holidays, I am quite free and do whatever I feel like doing and spend time with the people I care most. That's why I prefer to go to my hometown during my holidays rather than going to other places.

The environment is important because everything that supports the survival of human beings is dependent on it. It is simply the only home of mankind, making it the most important aspect in life. Wellness of the environment directly relates to the wellness and health in human beings and every other species. In addition, the environment provides remarkable beauty.

​Complex ecosystems and food chains in the environment provide unlimited services for the support of life. In the absence of damage, the environment is very efficient in self-stability through the complex interaction of living species. Humans benefit by being part of this ecosystem. Any harmful alteration to the components of the environment brings adverse impacts across all species. For instance, destruction of trees would lead to the accumulation of toxic gases and a shortage of oxygen in the air. As a result, protection against harmful rays of the sun would be disabled, causing uncontrolled temperatures and adverse health effects.

There is a significant threat in environmental degradation due to the advancement in technology and other human activities. This destruction is avoidable through environmentally friendly goals such as maintenance of excellent water quality, healthy air and the preservation of biodiversity. Every individual has a role in the achievement of these goals and, therefore, protection of the environment.
