【正文】 hird.But it has to be the light music. Lively music has no effect at all on sales. Slow music can increase receipts by 34%. This is probably because shoppers slow down and have more opportunity to spot items they would like to buy. Yet, slow music isn’t always the answer. The expert found that in restaurants slow music meant customers took longer to eat their meals, which reduced overall sales.

Near Earth, ozone in the air is a danger to life. It is a pollutant. But between ten and fifty kilometers up in the atmosphere, ozone protects life on Earth. Ozone forms in the atmosphere through the action of radiation from the sun. Ozone blocks harmful radiation from reaching Earth. Scientists say a decrease in ozone and an increase in the harmful radiation will cause many more cases of skin cancer. And it will harm crops, animals and fish.Ozone problems first became known in 1985. British scientists reported that ozone levels in the Antarctic atmosphere near the South Pole fell sharply each year in October and November. 1987 was the first year that a huge hole developed in the ozone layer above the Antarctic.A recent study of the atmosphere over the Arctic area near the North Pole showed extreme thinning of the ozone. Officials from the American space agency said the latest study is a result of the largest campaign yet to measure ozone amounts and changes in the Arctic area. NASA researcher Paul Newman said some of the measurements show ozone in the Arctic decreased about sixty per cent between January and the middle of March. These measurements are similar to the ozone losses observed in this area a few years ago.Other studies have shown that manmade chemicals were destroying ozone in the atmosphere. An international agreement halted production of the most harmful chemicals. The new findings support the idea that recovery of the ozone layer may be delayed.Q1: Where can ozone be found useful to life according to the passage?1. A. In the lower atmosphere. B. In the upper atmosphere. C. On Earth. D. Near Earth.Q2: When did ozone problems first bee known?2. A. In 1978. B. In 1980. C. In 1985. D. In 1987.Q3: What is the passage mainly about?3. A. Ozone as a form of oxygen. B. Problems caused by the thinning of the ozone layer. C. Some studies of ozone problems. D. The latest studies of ozone problems.Passage 5 Script of Passage 5:Gene Perret has been a joke writer for twenty years and has taken hundreds of flights. So he was only half listening when the air steward began going over the safety instructions. Suddenly Perret’s ears stood up “There may be 50 ways to leave your lover,” the steward said, “but there are only five ways to leave this airplane.” And then he added: “Please return your seat to its upright and most unfortable position. Later you may lean back and break the knees of the passenger behind you.”P(pán)erret uses the air steward story to make a serious point: humor can catch someone’s attention and get a message across. “Some people can’t tell a joke to save their lives,” says Perret, “but everyone can learn to use humor effectively. The secret is developing your own style, learning a few tricks and taking the time to practice.”The first step Perret remends is to build up a “edy collection”. Note down 25 jokes or stories that you find funny. Then work out whether you are better with stories or onelin
