Hi Joe, 
Last Saturday, I went to .The concert. It was great! A lot  Of my favourite groups and singers were there. The concert was to get money to help poor people in Africa. I think it’s important that the richest countries  Of  the world help some of The poorest countries. 
Anyway, the concert was really exciting. I always think that listening to live music is better  than listening to a CD. However, I hated one new singer. I can’t remember  Her name but she was really bad! The other problem was that I couldn’t always see very well because there were a group of tall boys just in  Front of me. Apart from that, I had a great time.
What about you? What Did you do last Saturday? Write back and tell me. 
All the best

People in London in the mid-nineteenth century greatly feared cholera. At this time doctors(believed) that cholera (circulated) through the air, and (did not realize) that all the time raw sewage (was entering) water supply, and that the disease (spread) through the domestic water system. Although in the 17th and 18th centuries London (possessed) a water supply system and a sewage system which were the changing situation. Broken water pipes and sewage pipes often (flew) into one another, and most sewage (ended up) in the River Thames, which was the main source of drinking water for thousands. Between 1831 and 1867 a series of severe outbreaks (occured). In the outbreak of 1848-49, there were over 30000 cases of the disease in London, and 15000 people (died). By the mid 1860s the situation (had improved) mainly because by then engineers (had been working on) the construction of a completely new sewage system, which they (completed) in 1875, and which is still in use today.
