Write a conversation between Lena and Rob. They have to explain each other what happered. Use so, so that, that's why and because.

ТЕКСТ:
Rob met Lena in the Hot Site Cyber Café last year. A friend introduced them to each other, and he liked her from the first moment he saw her. She seemed a really nice person, and he thought she was incredibly attractive. She was with another boy that evening, so he didn't ask her out. He saw Lena in the café again the next Saturday. She was surfing the internet. This time she was alone, so he sat down next to her. Before long they were talking and laughing. They started to go out together. Today was a very special day. It was exactly a year since Rob and Lena started going out together. This was their first anniversary, and he wanted to buy her a present. The only problem was that he didn't know what to buy her. 'I know!" he thought. I'll ask my cousin Jane. She's always got a lot of bright ideas." Jane suggested perfume because 'all women love perfume.' However, Rob didn't know anything about perfume that's why jane went shopping with him. She took him to a very expensive shop so that they could choose something nice. Lena saw Rob with Jane when they were buying the perfume. Lena didn't know Jane. She was very jealous and very, very angry. She wanted to shout at them! But she didn't. She left the shop without saying hello, and decided never to see nim again. Rob never knew. Lena saw him with Jane. Rob telephoned Lena. He wanted to give her the perfume and celebrate their wonderful year together. Lena was crying when he rang. She asked her mother to tell hir that she was out - with another boy! Rob felt his heart brecking. 'I just don't believe it! How could she do this?" he asked himself. Lena and Rob split up..​

земли. Так, например, в 1955-1958 годах в Павлодарской области были распаханы
темно-каштановые почвы легкого механического состава.В результате 805 тыс. га
были подвержены эрозии и стали непригодными для земледелия, привела к потере
кормовых угодий.
В результате неправильной распашки происходит уплотнение почвы,
сопро-вождаемой потерей гумусного слоя, микроэлементов.Плодородный слой
почвы при неправильной распашке часто смывается выпадающими осадками, или
развеивается ветром, происходит образование оврагов.
