听力原文： Around the world more and more people are taking part in dangerous sports and activities. Of course, there have always been people who have looked for adventure—those who have climbed the highest mountains, explored unknown parts of the world or sailed in small boats across the greatest oceans. Now, however, there are people who look for an immediate pleasure from a dangerous activity which may only last a few minutes or even seconds.
Bungee lumping is considered to be a good example of such an activity. You jump from a high place about 200 meters above the ground with an elastic rope tied to your ankles. You fall at up to 150 kilometers an hour until the rope stops you from hitting the ground. It is said that 2 million people around the world have now tried bungee jumping. Other activities which most people would say are as dangerous as bungee jumping include jumping from tall buildings and diving into the sea from the top of high rocks.
Why do people take part in such activities as these？ Some psychologists suggest that it is because life in modern societies has become safe and boring. Not very long ago, people's lives were constantly under danger. They had to go out and hunt for food, and life was a continuous battle for survival
Nowadays, according to many people, life offers little excitement. They live and work in relatively safe conditions; they buy food in shops; and there are doctors and hospitals to look after them if they become ill. The answer for some of these people is to look for danger in activities such as bungee jumping.

Why did Mr. Moore write the letter to the newspaper？
You are the database administrator for a retail company. The company owns 270 stores. Every month, each store submits approximately 2,000 sales records, which are loaded into a SQL Server 2000 database at the corporate headquarters.
A Data Transformation Services (DTS) package transforms the sales records, as they are loaded. The package writes the transformed sales records to the Sales table, which has a column for integer primary key values. The IDENTITY property automatically assigns a key value to each transformed sales record.
After loading this month's sales data, you discover that a portion of the data contains errors. You stop loading data, identify the problem records, and delete those records from the database.
You want to reuse the key values that were assigned to the records that you deleted. You want to assign the deleted key values to the next sales records you load. You also want to disrupt users' work as little as possible.
