Lynne Shaner used the Internet to buy everything she needed for her wedding and holiday gifts for her husband and step-daughter. Other than food, 90 percent of her purchases are made on the computer in her Washington apartment. "If I find that, by being able to go online and choose the things that I need to choose, and have them delivered to me right at my doorstep, I eliminate all the driving, all the crowds, all the noise of that, and usually get a better selection," Shaner explained. Analysts say US online shopping has hit record highs in November and December. Fifty-seven percent of Americans have made at least one online purchase. Traditional merchants worry that the growing e-commerce will shrink their share of the market. Cornell University Marketing Professor Ed Mclaughlin says they have a reason for concern. "Anything that can move online will go. It is just a matter of time," he stated. Mclaughlin says traditional stores can keep their customers by offering goods like clothing, which customers may want to see and try on before purchasing — as well as items that are difficult to ship. He says some bricks and mortar stores are also pleasing customers with services that set them apart from computers and electronics. Traditional stores also offer a social experience that some shoppers enjoy. "Often times, you need that last sense of 'this is exactly what I want' before you part with your money," he said. "And you can't always get that online. It's a rather cold process. Traditional stores can also deliver goods more quickly than online retailers," Martins says. And smart merchants are using their websites to encourage customers to visit their stores. While e-commerce worries some merchants, it's a huge boost for delivery services like FedEx and UPS. UPS Manager Dana Klines says e-commerce is helping her company be even busier than usual this time of year. "We are expecting 28 million pieces on the holiday season to deliver gifts. Those packages are headed for homes, including Lynne Shaner's purchase. Analysts say US online shopping has hit record highs in November and December. What can we infer from the passage?

Today I'll be talking about the invention of the camera and photography. The camera is often thought to be a modern invention, but as early as 1727, a German physicist discovered that light darkens silver salt. Used as a camera, a big box was set up, and a small hole was cut in one side to let the light in; he made temporary pictures on the salt. Silver salts are still the basis of the photographic film today. Then a French scientist made the first permanent picture by using a special piece of metal which was covered with silver salt. A photograph made in 1826 still exists. The painter De Gears improved the process by covering the metal also with placing the common salt which we can see in 1839, the official date of beginning of photographs. But the problem was that the printing of the photographs. And it was not until other scientists developed the kind of photographic paper we now use that good prints were possible and photography became truly modern. In the 1870s, Matthew Brady was able to take his famous pictures in the American Civil War. In the 20th century, Georges Mann of the United States simplified film developing, and Dr. Edward Lane invented the so-called 'Instant Camera' which uses itself to develop film. If we say photography came into existence in 1839, it follows that it is more than 100 years for the camera to reach its present condition of technical refinement. What is the main idea of the passage?
