听力原文：A study done in Greece says people can live longer and healthier lives if they eat what is known as the Mediterranean diet. Such a diet generally gets about 40 percent of its calories from olive oil and other fats that are considered healthy. Researchers from the University of Athens and Harvard University Medical School in Boston, Massachusetts did the study. They published the results in the New England Journal of Medicine. Researchers say it is all the foods together in the Mediterranean diet that make the difference. So they say people should eat a lot of fruits, vegetables, beans and fish. And they should use olive oil in their cooking.
The following places are likely to be involved in the research EXCEPT ______.

听力原文：On September 13,1956, IBM shipped the first unit of the RAMAC, in other words, Random Access Method of Accounting and Control. The RAMAC, designed in Big Blue's San Jose, Calif., research center would have made a lousy music player. The drive weighed a full ton, and to lease it you'd pay about ＄250,000 a year in today's dollars. Since it required a separate air compressor to protect the two moving "heads" that read and wrote information, it was noisy. The total amount of information stored in its 50 spinning iron-oxide-coated disks-- each of them a pizza-size 24 inches -- was 5 megabytes.
Which of the following is true according to the passage？
听力原文：Picture this: A foraging squirrel comes into range of a hungry, coiled rattlesnake. The squirrel realizes the danger too late -- the rattlesnake strikes out and bites, fangs pumping venom deep into the squirrel's small body. The poison doesn't kill immediately, but the squirrel's death war- rant is signed all the same. Even as he squirms away from the snake and bounds to his hiding place in the underbrush, the venom works its way through his system, dissolving his tissues and eventually killing him. Meanwhile the snake slithers after the departed squirrel, taking his time. Uncannily, he homes right in on the squirrel's hiding place. How did the snake know where his prey was hiding？ Do snakes have some kind of magical sixth sense？ Actually, snakes DO have a kind sixth sense, but it has nothing to do with magic.
Although snakes often have very sharp vision, a sense of smell, and a sensitivity to heat and vibrations, their most important sensory system is one that we humans don't share with them at all. This sixth sense is called the "vomeronasal system", and the sense organs for this are two tiny, bulb-shaped structures located on the roof of the snake's mouth. This sensory system is somewhat similar to smell -- in that it senses the presence of chemicals in the snake's environment. Snakes can use this extra sense to detect the faint chemical traces left by departing prey, or they can use it to track down a mate. On our next program we'll learn how snakes use their flicking, forked tongue to aid this sixth sense in the quest for prey.
