7 минут=7*60=420 сек. 1 минута=60 сек. (420+2)-(60+35) 422-95=327 сек.=5,45 минут=5 минут 27 секунд.

Read the text "Clothes and fashion in our life".

Olivia-Palermo-Fashion-Magazine-March-2016-Cover-Photoshoot01.jpg

Most people believe that it's important to look nice. However, some people say that we place too much importance on appearance and fashion.

One will hardly disagree that it is pleasant to look at a person who is neatly and beautifully dressed. A person usually chooses clothes according to his or her age, social class, financial position and occupation. People also choose clothes according to their preferences and character.

To my mind, if a person wants to produce a good impression and to be successful, he or she must look nice. When people speak to you, they always pay attention to your appearance and your clothes. If you look sloppy and untidy, they will try to avoid you. There is a saying that "good clothes open all doors" and I quite agree with it.

But some people place too much importance on their appearance. They spend much money on expensive clothes and sometimes they look ridiculous trying to be fashionable. There are some styles that can surprise and even shock people such as punks, hippies or Goths. It looks strange when a person wears razor blades instead of earrings, dyes his or her hair bright red or purple or puts on shoes on enormous platform. Some teenagers are fond of bright make-up, black fingernails, scruffy long hair or baggy clothes. But I think it is silly to slavishly follow the current fashions.

In conclusion, I'd like to say that nowadays fashion becomes even more influential than it was in the past. It effects and moulds public taste. I believe that people should follow fashion and pay attention to their appearance, but it should never become a kind of obsession.

Fill in the phrases:

1. look --------- and untidy

2. money on ---------- and sometimes they look ridiculous

3. moulds -------- taste
