Dangerous infection Cholera is a disease spread by dirty water, either when people drink the water, or eat food which has been washed in the water, and not properly cooked.Unfortunately, until the mid 19th century, people believed that the disease travelled through the airIn the crowded cities of 19th-century Britain, cholera spread easily. Most doctors wrongly believed that fresh air and better diet would prevent the disease.Huge fires were usually lit in the streets to drive away the infection, and the clothes of victims were also bumned. The streets were also cleaned thoroughly withpowerful chemicals. However, people continued to suffer dreadfully.In 1854, a doctor in London, John Snow, definitely proved that cholera spread through infected drinking water He did it by carefully collecting statisticsabout the infection in one part of London. He managed to prove that in an area where deaths from cholera were highest, the water was entirely responsible forcholera infection.Improvements made to sewers and supplies of drinking water led to a decrease in deaths from cholera.It in the third paragraph refers to

‘Work-life balanceRonan. I work in a fairly traditional office environment doing a typical nine-to-five job. I like my job, but it’s annoying that my commute to work takesan hour and a half each way and most of my work could really be done online from home. But my boss doesn’t seem to trust that we will get any work doneif left to our own devices, and everyone in the company has to clock in and out every day. Its frustrating that they feel the need to monitor what we do soclosely instead of judging us based on our task performance.Jo. Tused to do a typical five-day week, but after I came out of my maternity leave, I decided that I wanted to spend more time with my children beforethey start school. After negotiating with my boss, we decided to cut my working week down to a three-day work week. This of course meant a significant cutin my pay too. I've since noticed, though, that my workload hasn't decreased in the slightest! 'm now doing five days’ worth of work in three days, butgetting paid much less for it!Lily. I'm a freelancer and work for myself. This is great because I am in control of what I do and how I spend my time. At first, T was working fromhome, but I found it really hard to concentrate. There were just too many distractions around: housework that needed doing, another cup of tea, my family‘members wanting my attention for various things. So, I started to go to a nearby café to work, but the Wi-Fi connection wasn't ideal and I found myselfdrinking too much coffee. In the end, I decided to rent a desk in a co-working space with five other freelancers like myself. I liked getting dressed to go towork in the moming and being able to focus in an office environment.Freelancer is a person who

Some facts about dodos‘When the last member of a species dies, we say that the species has become extinct. There aren’t dinosaurs left alive because they died out millions of yearsago.Some plants, birds and animals are still in danger from human beings. This is often because human beings destroy the habitats of animals, so that they don’thave any food to eat.‘When an animal or a plant becomes extinct, this can affect the plants and animals which depend on it for food. For example, there aren't any dodos leftalive. This bird once lived on the island of Mauritius where there weren't any animals to eat it. It couldn't fly, and soon became an easy meal for dogs and ratsbrought to the island by Europeans in the 16th century. Within a hundred years, the dodo became extinct, and although we still have paintings of dodos, therearen't preserved examples.Scientists have recently found bones on the island, but nothing else is left of the dodo.The dodo disappeared because of

Discoveries of Schliemann Heinrich Schliemann was a German archaeologist who excavated a city in Turkey in 1871 and decided that it was ancient Troy. He found evidence ofdestruction by war, and also discovered some gold objects. Nowadays archaeologists believe that his methods of excavation were unscientific, and they alsobelieve some of his discoveries were false.Recently many experts have said Schliemann had a habit of not telling the truth, and this has raised doubts about his work. For example, he said he wasa US citizen, but in fact it wasn't true. He also said he had a degree from the University of Rostock, but in fact the university rejected his thesis. He said he hadfound gold jewelry but some people believe these were modem pieces. In fact, his servant later told people that no jewelry had been found in the places whereSchliemann claimed to have found it. He also told the authorities in Turkey that he was an archaeologist, but he didn’t have any qualifications.However, although many archeologists at the time said his work was inaccurate, we have to remember archacology was not a science in Schliemann’stime. He may not have always told the truth, but he brought a lot of energy to the discovery of the ancient world, and devoted his life and his wealth to hisexcavations.According to the text, the true statement is ...

Interesting facts about dinosaurs Antarctica is mainly known for the penguins and seals that live there, but recently scientists have discovered the remains of two dinosaurs that lived theremillions of years ago. These are not the first dinosaur fossils that have been discovered in Antarctica. The first new discovery was a plant-eating dinosaur whichwas found by a mountain climber Scientists that examined the fossils say it is a plant-eating dinosaur that is nearly 200 million years old. The parts of theanimal they examined suggest that it was nine metres long and two metres tall. Dinosaurs which have been found in other parts of the world are as long as 30metres, however. So this specimen, the discovery of which has excited researchers is rather small.On the other side of Antarctica, dinosaurs bones that were discovered by accident have also proved interesting. This second dinosaur was a meat-eater whichstood about two meters tall. Scientists who were sheltering from bad weather found the bones near the sea. The dinosaur they discovered, whose bones werenext to fossils of sea life, probably died and was washed out to sea after its death. Dinosaurs are creatures that could not survive in cold conditions, but in theirtime, Antarctica was different. It didn’t have the cold climate it has today, but was warm and wet.The information omitted in the text

Thishuge project probably involved all the people who could work. We can also assume that it must have been designed and planned. Most pyramids were tombs,but now they are empty inside. The Giza Plateau is located on the easter outskirt of the city and is where you'll find the Giza pyramid complex. This site ishome to a total of nine pyramids. Also it is commonly referred to as the Giza Necropolis, since each pyramid holds the remains of members of the FourthDynasty.If you ask people whether there were pyramids in Greece, they would probably answer ‘No’. People all suppose that the Egyptian pyramids are the oldest,but this may not be true. We don’t visit the Greek pyramids of Hellenikon, but in fact it may be older than any of the Egyptian pyramids. Nobody knowsexactly why it was built, but it is believed to be a monument over the tomb. It's not one of the seven wonders of the world, but it is an interesting thing.‘There is no exact fact about the ..

Read the text and answer the question Many ancient peoples had their own calendars. Many primitive cultures used a four-day week, possibly in honor of the four directions. Central American peoples used a five day week; Assyrians (now Turkey) had a six-day week; Pre-Christian Romans in the 1* century BC had weeks of eight days called nundinae. For many centuries ancient Greeks — like Babylonians (ancientpeople who also lived in what is now Turkey and Iran) and Egyptians of the same period — divided their 30-day months into three ‘decades’ of ten days. The biggest change in calendars was brought by Julius Caesar in 46 BC, who extended future calendars to 365 days a year. The 365 day calendar is called the Julian Calendar in his honour.
