Many people like the feeling of the gentle wind in spring. Many like to see the falling leaves dancing in the wind in autumn. But sometimes, when the wind becomes a storm, it can be very destructive(具有破坏性的).

   A series of such storms struck the US last month and caused very serious damage and human pain.

Every year, major storms cause many problems around the world. There is nothing people can do to stop these powerful forces of nature. But new techniques are helping scientists to predict(预测) how, when, and where big storms will happen. The more exact scientists’ warnings are, the better people can prepare for the storms.

Predictions are improving. “We’re gotten better over the years, especially the last few years,” says Phil Klotzbach, a scientist at an American university. How is a storm formed? Even if scientists know where a storm will happen, winds can suddenly change, carrying the storm to a new direction. “For a hurricane to happen, conditions have to be just right, ” Klotzbach says.

First, the ocean water needs to be warm enough so that it evaporates and rises into the air. As it rises, the vapor(水蒸气)cools and turns back into liquid. This process gives off heat. This produces energy like an engine that causes winds to increase. It drives the formation(形成) of a hurricane.

If wind speeds reach 40 miles per hour, the system is called a “tropical storm”(热带风暴), and it gets a name. At 75 miles per hour, it becomes a hurricane.

Hurricanes that hit the US start when a thunderstorm forms off the coast of Africa. Storms also develop over tropical waters in other parts of the world.

On average, 60 or 70 storms form off Africa every year. About 10 of them get names. There are usually about six hurricanes. Two tend to be very big, with winds of 115 miles per hour or higher.

The hurricane season lasts from June to November. Ninety percent of all hurricanes hit in August, September, and October.

May the first is an important date in the college admission process in the United States.This is the last day for high school seniors to accept or reject offers of admission in the fall.But according to a recent report, there is a great change.Acceptance rates at the top colleges this year were lower than ever.    

These days, college applicants are applying to more colleges because online and common applications make the process easier.      On the other hand, deciding students for top colleges to accept can be difficult because it takes much time.Students may not like being put on waiting lists.Also, common colleges work more to get the students they accept to accept them.Some colleges hold visiting days that offer a chance to attend classes and stay overnight.Some universities send gifts.        

For many families, the most important thing colleges can do is show them the money, especially this year; the weak economy makes parents nervous.      The recent problems that spread from the housing market to credit markets have even affected student’s loans.So lately, top schools have to spare lots of money to increase their financial aid for students.

         The Education Department expects the number of high school graduates to start to go down.This will happen as the last of the children of the baby boom generation finish high school.The number is not expected to start rising again until 2015.
