Na wstępie, nie zjedzcie mnie tak bardzo za błędy:)
1) There was conference on eviromental pollution in my school. At the beginning one person (was taking?)that people very pollute soil, air and rivers. Then, the other woman showed photos. In the photos I could have seen dirty rivers, dead animals and plants. Finally, the man told us what we can do to decrease(zmniejszyć)the eviromental pollution. Students were given leaflets and ecological bags.
2)There was action " clean- up the world" in my school once a year. In this year, the head teacher announced the action. On Monday, about 150 people went to the nearest forest. We collected rubbish and then assort (them?). We were concerned in action and we felt happy, because we could have done good something for our planet.
3) Jennifer Lopez went to our school. She is famous songer, dancer and actress. She recorded a lot of hits for example " If you had my love" We prepared the huge cake, which was similar to the artist. She was very friendly and kind, because she took photos with us and sign (one's - jak to zamienic?) autographs.
