On Sunday we went an a day trip to London. It (was raining) when we (started) and a strong wind (was blowing). But when we (arrived), the rain had already (stopped) and only little white clouds (were flying) across the sky. We (were) sure we (would have) a wonderful day. And we (did). We (visited) the National Gallery and (felt) quite happy. After that we (saw) a colorful procession (walking) along the Mall. At 2 o'clock our group (was) in the Tower of London. There we (were told) a lot of legends: about the ravens who (live) there and about the kings and queens who (had lived) there. It had already (become) quite hot when we (left) the Tower. So, our teacher (lead) us to Hyde Park where we (found) some shady place and (watched) the ducks (floating) in the water.

There are a big veriety of insects, but i want to speak about fly. It's one of wiedly spread insect in the world they live everywhere: in our houses, in parks e.t.c
Of course they looks ugly, but they make useful things such as collecting rubbish. But also this insects have disadvantages too and this disadvantages are really very serious! The mail problem of them it's their ability  to spread infections.
In conclusion i want to add that we need to overcome problems which connected with insects, but we mustn't kill them, because insects also make a lot of usefull things for us.
