听力原文： A lot of people in the United States are coffee drinkers. Over the last few years, a trend has been developing to introduce premium specially blended coffees known as gourmet coffees into the American market. Boston seems to have been the birthplace of this trend. In fact, major gourmet coffee merchants from other cities like Seattle and San Francisco came to Boston, where today they engaged in a kind of coffee war with Boston's merchants. They are all competing for a significant share of the gourmet coffee market. Surprisingly, the competition among these leading gourmet coffee businesses will not hurt any of them. Experts predict that the gourmet coffee market in the United States is growing and will continue to grow to the point that gourmet coffee will soon capture a half of what is now a 1.5 million-dollar market and will be an 8 million-dollar market by 1999. Studies have shown that coffee drinkers who convert to gourmet coffee seldom go back to the regular brands found in supermarkets. As a result, these brands will be the real losers in the gourmet coffee competition.

听力原文： Astronaut Steve Robinson is going where no one has ever gone in orbit--to a shuttle's underside, which is covered with thousands of fragile ceramic tiles as a barrier to the scorching heat caused by high-speed friction with the atmosphere. Slivers of heat-resistant fabric filling the thin gaps between the tiles have popped up a couple of centimeters in two places. Engineers worry that the protrusions might change the aerodynamics of Discovery's reentry Monday and make some parts of the orbiter a few hundred degrees hotter than normal. They do not know if the shuttle can with stand the extra heat. So astronaut Robinson's task is to stand on the end of the robot arm mounted on the International Space Station, where Discovery is docked, and either pull out or trim the gap filler. He must be very careful not to strike and damage the delicate tiles with his space suit or tools, as he explained to reporters.
