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(具有破壞性的).

   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(預(yù)測) 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（水蒸氣）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”(熱帶風(fēng)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.

A lady and her husband stepped off the train in Boston. They walked without an appointment（預(yù)約）into the outer  31_ of Harvard’s president(哈佛大學(xué)校長).

The secretary finally decided to disturb the president, though  35  .

A few minutes later, the president walked towards the couple with a  36  face. The lady told him, “We had a son that  37_ Harvard for one year. He loved Harvard. He was  38  here.

We have spent over ＄7,500,000 on the campus building at Harvard.” For a moment the lady was silent. The president was  46  , because he could get rid of them now. Then the lady turned to her husband and said quietly, “Is that all it costs to start a  47  ? Why don’t we just start our own?” Her husband nodded.  48_ their offer was turned down, Mr. and Mrs. Stanford traveled to California where they founded the University that bears their  49  , a memorial to a son that Harvard no longer  50  about.
