Подскажите глаголы в past continuous когда в past continuous используется when, а когда while

Глаголы: was (если i, he, she, it), were ( если they, we, you). when (когда) - однокраиное действие + длительное. когда зазвонил телефон (однократное), я смотрел телевизор. while (в то время как) - два длительных действия одновременно. в то время как мама готовила обед, я мала посуду.

Надеюсь, не зря мучалась. :D

Choosing a profession is a very responsible and important moment in the life of each person because their future depends on it. The profession of a guide is one of the most popular, as each year tourism is developing faster and faster. The task of the guide is to broaden the horizons of people. Thanks to their work tourists become more educated and cultural.

From the age of 10 I started traveling with my parents, I have visited many excursions, and each time I imagined myself in the place of a guide. I dreamed of going to the tourism, and now it came true because my future profession allows not only to help a person with the search for the most interesting country for him but also to visit the most in many countries and find an unforgettable experience. It is possible to work as a guide and to conduct excursions in different places and cities, it is very interesting to me because I can study history not only for myself but also to inform people useful information about which they did not know before. Our city is full of attractions and beautiful places that I would like to tell you about. I hope in the future I can connect life with tourism.

Iam an ordinary teenager aged 16 and like any other person i have friends. i have a lot of friends and i spend almost all my time with them.топики по языку but there is only one person who knows and understands me best of all. this only person i can call my best friend.her name is helen. she is one year older than me. we have known each other since i was 5 and she was 6. our first meeting started with a quarrel for a doll. and exactly at that moment we understood that there is something much more important than a doll. it was our friendship.as small kids, we spent all the time together playing, walking, and talking. and now when we are teenagers we have less time to spend together because we study in different places. she is a student at a technical school and she studies to become a secretary. nevertheless we try to phone each other and to share our news every spare minute. also we like to spend the nights together. but we do not sleep, we gossip and chat the whole night. i think that all girls do the same.  helen doesn’t like to study at all. her marks at school sometimes could be better. although i am one year younger than she is, i sometimes help her with her home tasks. she is interested in absolutely other things: fashion, clothes and boys.helen is very pretty. she is slim and not very tall. she has blond long wavy hair and blue eyes. she is very attractive and she always attracts young boys with the help of her charming smile and glamorous appearance. she likes trendy clothes and she wears a lot of jewelry. she likes boys. she has already had several boyfriends but she didn’t treat them seriously. i don’t consider her to be careless i just think she wants to live life to the hilt. sometimes i think that we are too different and do not understand what connects us. but i am sure that these differences make our friendship stronger. at least i can’t imagine my life without helen. i really hope that we will stay best friends till the rest of our lives no matter what happens.
