Pearl corder S702 $64 This simple model at the bottom of the Olympus range scored the most points for its excellent quality of recording. Background noise hardly affects the sound and recording from a pocket is perfectly possible, but it doesn't turn off automatically. Tape length: 30 minutes per side. Weight : 240 g Sony M9 $49.95 Small and very good looking, Sony's latest offering scored most for appearance. Sounds clear, but there is slight machine noise. The big control buttons are a great improvement on some of the complicated little controls on other tape-recorders. Doesn't switch off automatically but a red light shows if the machine is still running. Tape length : 60 minutes per side. Weight : 195g. Sony M400 $115 Lots of little control buttons that make a noise and are difficult to use. Rcording is good but machine noise loses points. Tape counter and automatic switch-off when tape has finished recording or rewinding are useful. Tape length : 60 minutes per side. Weight : 230g Imperial OEM MC7 $29.95 Cheap and simple compared with the rest, but recording is good as long as there is no background noise. Use only its own make of cassette. No light to show it is on; no fast forward button and the record button makes a loud noise. Tape length: 30 minutes per side. Weight: 285g. Philips 585$ 80 Handsome and simple to use, but recording is very poor at more than the recommended distance of 5 cm designed for dictation. No recording light. Tape length : 15 minutes per side. Weight : 220g. Question: What disadvantage does the Imperial OEM MC7 only have? - It picks up background noise - It requires a special cassette - The record button makes a noise - No light shows when it is on
It requires a special cassette

Well, three lucky American teenagers were able to do just that. The teens--two males and one female--got an all-expenses paid, yearlong hike to five continents. This trip didn't include any five-star hotels or shopping funs. Eighteen-year-old Jamie Fiel from Keller, Texas, 17-year-old Arsen Ewing from Canyon, California, and 16-year-old Tyler Robinson from Lincoln, Massachusetts, didn't expect fancy treatment. They signed up for the experience of a lifetime, which included hard work, often uncomfortable accommodations, and encounters with some of nature's most dangerous animals and environments. Jamie, Arsen, and Tyler were among hundreds of high school kids nominated by their science teachers to take this trip. Earthwatch Institute sponsored this adventure. Each year, Earthwatch employs thousands of volunteers worldwide to help with scientific research projects. The group went all around the world to get a close look at the most pressing environmental issues of our time. Their assignments were as varied as their locations, and included measuring and attending pink flamingos in Kenya's Great Rift Valley, and tracking giant sea turtles in Costa Rica. As they worked with the Earthwatch scientists, Jamie, Arsen, and Tyler began to understand that we are at a critical moment in the life of our planet. Time for change is running out. As the teens went from country to country and witnessed different environmental dangers and challenges, they understood that solutions to important environmental issues start with the power of one person's actions. They realized that each of them can make a difference. Question: These teenagers went on the journey around the world _ . - to experience the most serous environmental problems on the earth - to bring the kindness of America to the other parts of the world - to go on sightseeing around the world - to call on more teenagers to join Earthwatch Institute
to experience the most serous environmental problems on the earth

Q: Read the following article and select the best answer. Article: In 1971, a young man who grew up very poor was traveling across the country, trying to make a new start for himself. Along the way he had completely run out of money and was forced to spend the night in his car. This continued until one morning, after a week of sleeping in his car, he walked nervously into a restaurant and ordered a big breakfast. After eating his first good meal in weeks, he lied to the waiter, telling him he had lost his wallet. This waiter, who was also the owner of the restaurant, walked behind the chair where the young man had been sitting. He bent down, and came up with a $20 bill that looked as if it had fallen on the floor and said, "You must have dropped this," the owner said. The young man couldn't believe his luck. He quickly paid for the breakfast, left a tip, bought gas with the money, and went to the West. On the way out of town, he began to understand what that man did. Maybe nobody dropped the money. "Maybe that man knew I was in trouble and he helped me in a way that didn't hurt me. So I just made a promise to help other people if I can." Later, he worked very hard and became a rich man. Now, he lives in Kansas City. Each year he gives away thousands of dollars. He is known as the "Secret Santa " because at Christmas time each year, he personally hands money out to those on the street and at restaurants. Question: The young man was traveling across the country in 1971 probably to_. - look for a good restaurant - hand out gifts to passers-by - find a new job - show his new car to others
