You could see many concerned people with masks trying their best to stop the swine flu . And the masks aren't only being used in Mexico. A friend of mine traveling from New York City to Florida was given a mask and a pair of gloves just after he reached the airport. And another friend went to get a haircut only to be faced with a hairdresser wearing a mask! But do the masks really work? Is covering your nose and mouth the key to stopping the swine flu? To find out the truth, ABC's reporter Sharyn Alfonsi talked with germ expert Dr. Elaine Larsen. It turns out that when you sneeze the air coming out of your mouth at a speed of one hundred miles per hour carries germs which can travel anywhere around you and make people around you infected . However, whether you become infected actually depends on the weather. As Sharyn reported, when you sneeze, the germs leave your body in small drops of water coming out of your mouth. If the weather is wet, the wet air will make the small drops bigger and heavier and they drop down towards our feet. If this happens, we won't become infected. But if the air is dry, those small drops can float higher up, making it possible for them to touch someone else's nose, mouth or their mask. Larsen says the masks can stop the germs well but after a few hours, they start to get wet, holding a lot of germs they come across and causing you to breathe them in. The masks do work, but the key to stopping the germs is changing your masks often. Question: According to Para.1, in Mexico you can see that _ . Options: A: the patients are treated in the open air B: some doctors work in the street C: people speak little to each other in the street D: many people wear masks in the street

Ques: Read the article and select the best answer. Article: Baths and bathing have been considered of an important medical therapy to man. In Greece there are the ruins of a bath tub and water system built over 3 000 years ago. The Romans had warm public baths. In some public baths as many 3 000 persons could bathe at the same time. Treating diseases by bathing has been popular for centuries. Modern medical bathing, or _ , first became popular in Europe and by the late 1 700's also became popular in the United States. For many years frequent bathing was believed to be bad for one's health. Ordinary bathing just to be clean was avoided, and perfume was used to cover up body and smell. By the 1 700's doctors began to say that soap and water were good for health. They believed that it was good for people to be clean. Slowly, people began to bathe more frequently. In the United States ordinary bathing was slow to become popular. During the 18th and early 19th centuries, many Americans were known as "the great unwashed". In one American city, for example, a person could only take a bath every 30 days! That was a law. Frequency of bathing today is partly a matter of habit.

Ques: Read the article and select the best answer. Article: Barcodes aren't given much thought by the majority of consumers, but these codes were fairly recently applied in a working fashion in 1970. A small food store owner decided one day that keeping records of the inventory of his stock and the associated prices were an extremely laborious process, and so, in 1948, he contacted The Drexel Institute of Technology in a bid to work towards a solution. Bernard Sliver rose to the challenge and set out to study the problem and began working on a solution involving an automatic way of keeping track of items that had been sold. Sliver and a group of students from the institute realized their answer in the form of ultraviolet light , ink and a scanner. The system worked initially, but possessed some negatives. It was incredibly costly to carry out on a large scale and the system was also unstable. If the invention was to become commonplace in grocery stores, these two problems had to be solved. The patent for the bar code system was filed by Sliver and one of his students, Woodland. The patent was not granted immediately; in fact, it took three years for the patent agency to grant their invention patent for the barcode, occurring on 7thOctober, 1952. Despite the patent being issued, the system was still not welcomed by the majority of store owners. It was not until 1966 that the system began moving its way into more and more grocery stores. This system was soon criticized, as there was no central mechanism for controlling uniformly coded items. In 1970, Logicom developed the Universal Grocery Products Identification code( UGOIC), soon shortened to Universal Identification Number (UPC). It was Marsh's superstore, in Troy, which was the very first store to install this complex barcode reading system, and its popularity has soared ever since, and is obviously now commonplace in all types of stores worldwide. Question: What is the purpose of the text? Options: A: To tell people that failure is the mother of success. B: To praise scientists' efforts in making people's lives easier. C: To describe shop owners' opinions of barcodes. D: To provide information about the development of barcodes.
