1- a situation when you waited for a bus or a train 2- a challenging profession you know about

participate in some indoor or outdoor sports competitions. In fact, research 
works are not something that will attract the students. They perform the tasks 
as they need to pass the exam and often they adopt unfair means to cross the 
barriers of school boundaries. When they follow the unfair ways, they actually 
do not learn anything and this is mere a wastage of time and labour. If they are 
engaged in the activities they like most, then they would participate in the 
activities happily and the scores will be of expected level.
