Semi-conductors find wide application in designing electronic counters, because they react to all kinds of radiations. (Where?).One of the main engineering problems which could be solved by using semi-conductor was converting heat into electricity without using boilers or other machines. (What?).​

 There are many interesting and noble (1) professions. I want to be a doctor. It is an interesting profession.
   I understand that it is necessary (2) to study a lot to become a doctor. I also understand that this profession requires (3) great responsibility (4) because it deals with the most precious thing one has — with his health.
   My grandfather is a doctor and he works as a surgeon (6) in hospital. I have been several times at the hospital and spent some time watching him working.
   His main task is to operate on people. After each operation he takes care of the patients until they recover (7). He examines people and gives them professional advice. After operation people should follow his instructions. My grandfather says, if your health is good, you are always in good mood. It is very important for everybody.
   He is always kind and attentive to his patients. People feel that and trust him. That is why it is easier to treat them.
   I know that he wants to see all his patients able-bodie notice that he is happy when his patients recover.
   My grandfather can also help if somebody has caught a cold or has got a fever. He told me a lot of true stories about doctors and their profession:
   I love and respect my grandfather and I want to become a doctor as well. I'll do my best to help people who have problems with their health.

It is rather important for everyone to make the right choice of profession, because what we choose defines the largest part of our life. If someone chooses to be a teacher, he or she will spend most of the time dealing children. Those, who choose to become doctors, spend most of their adult life helping people to cope with various diseases. I chose to discuss different matters and argue about them. Basically, I want to become a lawyer. On daily basis I like investigating, finding out the truth, arguing and winning.
