The earliest simple computer, the Chinese abacus dates back to thousands of years ago, consisting of rows of beads on a wooden frame used for counting. The modern computer dates back to 1946, when the Electronic Numerical Integrator and Calculator (ENIAC) was invented. The U.S. Department of Defense developed the Internet so all of its own computers could be connected; in 1990 the World Wide Web was born. The rapid development of technology has resulted in the computers we use today, and those are changing as we speak too.

You can do many things on a computer. You can create and print letters or reports for school, and save those documents in case you need them later; you can watch movies, listen to music and play video games. The Internet allows people to visit different websites, send e-mails, shop online and pay bills electronically. Some people even work or receive schooling through their home computers.

The most common types of computers used are the desktop, the laptop and the handheld computer. Desktop computers stay in one place, and their parts are contained in a case that is placed beneath the monitor. Laptop computers are lightweight and small enough to be carried by users who need computers and the Internet access to them in different places. Handheld computers include personal digital assistants, small video gaming devices and mobile phones.

While computers make life convenient and are considered positive to society, there are negative aspects of computer use that kids and their family should consider. Computer viruses are harmful programs that damage information and can stop your computer from working properly. The Internet presents risks for young people, too. The information you share is not private. Some kids use their computers so much that they don’t want to do anything else.

1.The earliest simple computer was invented ________.

A.in 1946 B.in 1990 C.by Chinese D.by Americans

2.What kind of computer is liked most by people whose working place is not fixed?

London’s Chinese community dates back to the 18th century, when a small number of Chinese sailors moved to the city to work in Limehouse, east London. As time went by, other Chinese people came to this area and Limehouse began to be known as "Chinatown". At the start of the 20th century, there were just 545 Chinese people in Britain. However, this situation changed greatly after the Second World War. At this time, many farmers in Hong Kong lost their jobs, and decided to move to London. In the 1950s, a small Chinese restaurant opened in central London. Many British people visited it and said that Chinese food was wonderful! Suddenly, Chinese restaurants started opening in every part of the city. Instead of too little work, the new Chinese immigrants (移民) now found that they had too much! Most of the new immigrants enjoyed their lives and the chances they were offered. Many asked their friends and relatives to join them from their hometowns, and a lot of families were reunited again at this time.

As time went by, London’s Chinese community became more and more successful. The sons and daughters of the first restaurant workers, encouraged by their parents, studied very hard at school and university. And most got highly-paid jobs. As a result, increasing numbers of Chinese families left Chinatown and moved to the more expensive places. Chinatown, however, is still as lively as ever, and a must-see for any visitor to London.

Halloween falls on October 31st, the last day of the Celtic calendar. Halloween dates back to over 2000 years ago.

The American tradition of "trick-or-treating" probably dates back to the early All Souls' Day marches in England. During the festivities, poor people would beg for food and families would give them pastries called "soul cakes" in return for their promise to pray（祈祷）for the family's dead relatives.

The act of giving out soul cakes was encouraged by the church as a way to replace the ancient practice of leaving food and wine for homeless ghosts. The practice was finally taken up by children who would visit the houses in their neighborhood and be given sweets, food, and money.

The tradition of dressing in costume（服饰）for Halloween has both European and Celtic roots. Hundreds of years ago, winter was an uncertain and frightening time. Food supplies were often not enough because people were afraid of the darkness and would stay at home without doing businesses.

On Halloween, when it was believed that ghosts came back to the earthly world, people thought that they would meet with ghosts if they left their homes. To avoid being recognized by these ghosts, people would wear masks when they left their homes after dark so that the ghosts would mistake them for their fellows（同伴）.

On Halloween, to keep ghosts away from their houses, people would place bowls of food outside their homes to satisfy the ghosts and prevent them from trying to enter their houses.

1.Halloween falling on October 31st , has a history of more than 2,000 years.

2.During Halloween in America, poor people would be given food like pastries called “soul cakes” by rich family relatives.

3.Children would be treated to sweets and food while visiting the houses in their neighborhood on Halloween.

4.On Halloween, people would wear masks when they left their homes after dark in order to avoid being recognized by their fellows.

5.Halloween is a day honoring the dead and respecting the old.

Watercolour is the oldest paints known. It dates back to the early cave men who discovered they could add lifelike qualities to drawings of animals and other figures on the walls of caves by mixing the natural colours found in the earth with water.

Fresco, one of the greatest of all art forms, is done with watercolour. It is created by mixing paints and water and applying these to wet plaster. Of the thousands of people who stand under Michelangelo’s heroic ceiling in the Sistine Chapel, very few know that they are looking at perhaps the greatest watercolour painting in the world.

The invention of oil painting by the Flemish masters in the fifteenth century made fresco painting go down-hill, and for the next several centuries watercolour was used mainly for doing sketches or as a tool for study. It was not until the eighteenth and nineteenth centuries that English painters put back watercolour as a serious art form. The English have a widely-known love for outdoors and also small private pictures. The softness of watercolour had a remarkably strong attraction for them.

The popularity of watercolour continued to grow until the twentieth century. The United States passed England as the center for watercolour, producing such well-known watercolour artists as Thomas Eakins and Andrew Wyeth.

1.The purpose of the passage is to introduce _____.

A. the gradual weakness of fresco painting

Imagine that you are in a remote village somewhere with no medical clinic. 1.Once the doctors get to you, they examine you and take blood samples, but they won't be able to help you until they take the samples back to the hospital to find out what is wrong.2. Thanks to engineer Andy Ozcan, many people may never be in this situation. He has invented an app that turns your mobile phone into a diagnostic(诊断的)tool.

Ozcan's invention is important because it is very accurate and easy to use. In many remote places, even if doctors have microscopes and other instruments to help them make diagnoses, there may still be other problems. Many doctors, for example, don’t have enough training to correctly interpret what they see.3.With Ozcan's mobile phone app, health workers can take a special photo of a blood sample and send it to a central computer at a hospital. The computer will then automatically interpret the photo and send a diagnosis back in a few minutes.

4.His technology only requires a mobile phone and an Internet connection. As more than four billion people already have cell phones, the cost of establishing the diagnostic system is fairly low.

By inventing a medical tool that uses existing technology---mobile phones---Ozcan has developed a medical tool that is both practical and economical. Therefore, it can be effectively almost anywhere.5.

A.Another reason that Ozcan's invention is important is that it is inexpensive.

B.Even though you may only have a simple infection (感染), you might die because of the delay.

C.People are trying to reduce the cost of this new medical tool.

D.Ozcan's simple, cost-effective tool might just save millions of lives around the world.

E.This tool has become much more popular all around the world.

F.You become very sick and must wait days until a mobile medical unit arrives to help.

G.As a result, they may diagnose illnesses incorrectly.
