Твір на тему:

Життя- щонайтрудніше із мистецтв

власне висловлювання на тему "Життя! У ньому стільки переконуючої сили і повноти, що трудно дозволити собі байдужість чи слабкість" не могу ничего придумать, может у кого-то уже есть?

Ребят, ниже будут 3 текста и к ним вопросы, помогите ответить на них.С некоторыми вопросами затрудняюсь. Спасибо:*

Tracey Ponsford: All my classmates say that I’m trendy. Yes, I am! I enjoy wearing trendy clothes. I like to look cool and attractive. It’s very important to know what is in fashion at the present moment. I like shopping and spend hours picking clothes that suit me. My classmates say that I am interested in fashion too much, but it’s not that bad, is it? Sometimes I can appear in something really gorgeous. When you are up with the latest fashions you feel you are an individual. If I could I would wear different pieces of clothing every day. I wish I had lots of money to do that.

Phil Slager: I don’t care what I wear. More than that I don’t care what other people wear. My mum buys clothes for me at a market. Sometimes we have to shop in charity shops. Why not? Not all people can afford to be up to date with the latest fashions. I prefer casual things – jeans, T-shirts, sweaters or sportswear. My elder brother’s mates have spiky hair, tattoos and piercing. I wish my brother wouldn’t do that but he doesn’t listen. He says that they express their individuality. I don’t know if they are right or not but I would never have all those things.

Katya Guseva: Everyone in my class is really trendy. They spend a lot of time talking about clothes or accessories they want to spend their money on. Some friends of mine think that I’m boring and wear unfashionable things. Frankly speaking fashion is not very important for me. Fashion comes and goes. Looking clean and decent is more important than looking trendy, isn’t it? I prefer clothes which I feel comfortable in. I’m sure that you must feel good in what you wear and that is all. If I had a lot of money I would buy clothes which would never go out of fashion, or I’d rather buy some DVDs or a good book.
