Помогите пожалуйста) Задание на фото.

1) we are all aware of the dangers of being overweight and how hard it can be to lose weight this new health drink which my company has invented can help do just that it's better than other drinks because it has a new special formula that gives you all the vitamins you need without extra calories I won't give you all the technical details here but it has been thoroughly tested and is very effective so rather than process with other product I recommend that you try this new one I don't think you will be disappointed

2) I sold my old motorbike last month and got this new one well it isn't new actually it's second-hand I couldn't afford a new one about it is only a couple of years old and it's as good as new really there's hardly a scratch on it I was lucky to get it at such a good price he didn't cost much more than what I got for my old motorbike I get one if I were you but there aren't many around and you're unlikely to get such a good deal but it's really worth trying yeah go for it

3) high blood pressure is due to a buildup of cholesterol in your arteries this has probably been caused by eating too many fatty foods and smoking I can certainly prescribed some drugs that will help to bring down the high cholesterol but initially I'd like you to make some changes to your diet and increase your level of exercise try to avoid eating fatty foods such as cheese butter cakes and so on try also to exercise regularly ideally three times a week for 20 minutes or half an hour come back to me in 3-months if the level is still high we will consider a course of treatment at that point.

4) I came up with the idea for this about 5 years ago but only built in the past 12-months it's circular with handles on each side is battery powered rechargeable batteries of course they are inserted just here it's made of Steel and plastic and it allows you to browse the internet as well so it's a computer combined with the camcorder I've met quite a few people who might be interested in investing in it testing it because it'll take a lot of money or cost to develop and produce but I haven't heard back from them which is a bit worrying because I need money to start advertising it

5) you'll be delighted to hear that the new minibus which the school purchased has finally arrived it runs on biofuel which is sourced from plants so it is very environmentally friendly to get to and from matches quickly and easily we were able to purchase the minibus thanks to the money we made at the Christmas fair we are very grateful to all the people who donated unwanted items for the stored and who made all those delicious cakes and biscuits without you we wouldn't have this wonderful new bus I'm sure the bus will be in high demand from the word go
