Have you ever had the flu?  If you have, you know how miserable it can make you feel. Most kids will get the flu sometime during the school years. When you have the flu, you usually get a fever (which can be high), have a cough, feel very tired, and may have a sore throat as well. It can make you feel sick for a few days or for as long as a week.Sometimes, it can be hard to tell if you have the flu or a cold, but with the flu, you’ll usually have a higher fever and you feel much worse.

Money is that you use to buy things. You may earn money from completing household chores, getting good grades, for your allowance, or for losing a tooth! Money is very important in our world and comes in many different forms.

            People have been using money for hundreds of years. Before money gave specific values for things, people simply traded items.

            People earn money from the jobs they work and use that money to save for the future, pay for their houses, cars, food, taxes, medical needs and household items among other things. Even things such as turning the lights on, using the air conditioning or heat, and connecting the internet cost money.

Is it a bird? Is it plane? No, it’s a jet pod!

            Fed up sitting in traffic in the morning rush hour? Well, for London’s tired workers this may no longer be a problem. In a few years, “ flying taxis” or “ jet pods” may be a common sight in the skies of London. Commuters can park their cars at a “ Park – and – Fly” site and catch one of these miniature planes to work. Around 6 -6 minutes later, the planes will land on short runways in central London. The runways could be above rivers, railway stations or roads.

            The inventors of the “ jet pod” test flight could take place very soon. Each plane can carry 7 passengers and will probably cost about £15 one way for each passenger. It is quiet and environmentally friendly and will take about 37,000 cars off the road.

            So what do London commuters think of “ jet pod” ?  Well, Ken Williams, businessman in the City of London , thinks it is a great idea. “ This is exactly what London needs” he says.

I will definitely be first in the queue when the “ jet pod” starts!

World  language

Today, millions of people want to learn to improve their English but it is difficult to find the best method. Is it better to study in Britain or America or to study in your own country?

The advantages of going to Britain seem obvious. Firstly, you will be able to listen to the language all the time you are in the country. You will be surrounded completely by the language wherever you go. Another advantage is that you have to speak the language if you are with other people. In Italy, it is always possible, in the class, to speak Italian if you want to and the learning is slower.

On the other hand, there are also advantages to staying at home to study.  You don’t have to make big changes to your life. As well as this, it is also a lot of cheaper than going to Britain but it is never possible to achieve the results of living in the UK. If you have a good teacher in Italy, I think you can learn in a more concentrated way than being in Britain without going to a school.

So, in conclusion, I think that if you have enough time and enough money, the best choice is to spend some time in the UK.  This is simply not possible for most people, so being here in Italy is the only viable option.  The most important thing to do in this situation is to maximize your opportunities:  to speak only English in class and to try to use English whenever possible outside the class.

What is the article about?

• A. How many people learn English.

• B. The best way to learn English.

• C. English schools in England and America.

• D. How to travel to Italy.

Life in Tudor Times.

The six powerful Tudor kings and queens ruled England from 1485- 1603. The most famous king was Henry VIII, who married six times and beheaded two of wives. It was one of the most exciting times in Britain history but whether you rich or

poor, life could be very difficult.

Rich Tudors lived in fine houses with many rooms and big windows. Poor country people lived in small wooden houses with mud floors. In the towns, the streets were narrow, gloomy and crowded, which made it easy for criminals to steal from shops and people. Wealthy people and noblemen owned land or even helped The King or Queen to rule the country. Most people, however, were poor and worked in the countryside. Slightly rich people worked as craftsmen and merchants in the towns. Tudor shops had picture signs outside to show people what they sold, as many people could not read.

In Tudor times rich people often held huge banquets where they ate far too much. They had quite an unhealthy diet as they ate lots of very salty meat from the animals they owned or hunted. They also ate very little fruit, vegetable, milk, butter and eggs as they thought these foods were only suitable for poor people to eat.

It was the law that every man had to practice archery every Sunday morning! Rich people liked to fence and play tennis while ordinary people played games like bowls, hockey and football or went to the theatre. William Shakespeare lived in Tudor times. His plays are still performed all over the world.

Who lived in nice houses with a lot of rooms and big windows?

• A. Poor people

• B. The Queen

• C. Rich Tudor

• D. Craftsmen

Wonder dog pulls owner from the car crash.

Endal the wonder dog, already named Dog of the Millennium and Brightest dog on Earth, made national news headlines again yesterday after a car hit the owner’s wheelchair outside of a hotel.

In 1991, Allen Parton was sitting outside the hotel when the speeding car threw him from his chair and knocked him out. While he was unconscious, Endal rolled him over with his teeth into the recovery position. After this he got a blanket from his bag and covered him with it! The dog then got Allen’s mobile phone out of his bag and held the phone up to his face. Finally he ran back to the hotel and barked until people came out to help. Allen didn’t know that Endal could do any of these things. Mister Parton was disabled from the tragic accident. For years now , Endal has been everything to him: his best friend, his banker, his travel agent, his home help and many other things. “ He even buys the ticket on the bus and collects it from the machine” says Allen. “ He has helped me in so many ways”

Endal made the headlines again when

• A. a hotel worker hit his owner.

Bison have not always lived in North America, they are relative newcomers. They belong to the Bovidae family, like domestic cattle and wild buffalo of Africa and Asia. The oldest known bison fossils have been found in China and Himalayan foothills, where an animal with all the essential features of the genus lived a million years ago. They evolved rapidly and spread over most of the northern hemisphere in Europe and Siberia.

During one of the Ice Ages, the faunas of Asia and North America began to intermingle. Very early, the steppe bison moved eastward to the North American continent. Much later, men followed the same route.

Which of the following would be the most appropriate title for the passage?

• A.The classification of Asian and North American fauna

• B.A hypothesis of the evolution of the bison

• C.An analysis of the bison genus in the Bovidae family

• D.An introduction to the North American bison

For many years people believed that the cleverest animals after man were chimpanzees. Now, however, there is proof that dolphins may be even cleverer than these big apes. Although a dolphin lives in the sea it is not a fish. It is a mammal. It is in many ways, therefore, like a human being.

Dolphins have a simple language. They are able to talk to one another. It may be possible for man to learn how to talk to dolphins. But this will not be easy because dolphins cannot hear the kind of sounds man can make. If man wants to talk to dolphins, therefore, he will have to make a third language which both he and the dolphins can understand.  

Dolphins are also very friendly towards man. They often follow ships. There are many stories of dolphins guiding ships through difficult and dangerous water.

Which animals do people think may be the cleverest?

• A.Chimpanzees

• B.Mammals

• C.Big apes

• D.Dolphins
