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.

a. The ocean water evaporates and goes into the air.
b. Heat creates energy and causes winds to increase.
c. The vapor cools.
d. The ocean water is warm enough.
e. The vapor changes back into liquid.
f. This course gives out heat.
A.a, d, e, b, c, f B.a, b, c, f, d, e C.d, a, c, e, f, b D.d, a, b, c, e, f

B. The problem of drug overuse in America
C. Benefits of medicine and its wise use
D Female drug overuse with reference to that of males
E Misuse of medicine among the young generation
F. Improper use of medicine among senior citizens
1.
Nowadays. millions of people misuse and even overuse pain medications and other drugs. Research by the American National Institute on Drug Abuse (NIDA, 1999) shows that around 2% of the population over age 12 were using drugs non-medically.
2.
NIDA views medications as a powerful force for good in the contemporary world. They reduce and remove pain for millions of people suffering from illness and disease. They make it possible for doctors to perform complicated surgery to save lives. Many people afflicted by serious medical conditions are able to control their symptoms and become active, contributing citizens. NIDA points out that most individuals who take these drags use them in a responsible.
3.
Nevertheless, overuse of drugs such as opioids(类鸦片), central nervous system (CNS) depressants and stimulants does lead to harmful reliance in some people and is therefore becoming a serious public health concern. Although this abuse affects many people worldwide, particular trends of concern to the medical profession in the US appear among older adults, teenagers arid women.
4.
Though it may be a surprise to many, the misuse of medications may be the most common form of drug abuse among the elderly. Dr Kenneth Schrader of Duke University, North Carolina states that although the elderly represent about 13% of the US population, those aged 65 and over account for the consumption of one third of all drugs. People in this age group use medications roughly three times more than the general population and have poorer compliance with instruction for use. In another study of elderly patients admitted to treatment programs, 70% were women who had overused medicines.
5.
Unfortunately, this trend among women does not only affect those aged over In general, among women and men who are using either an anti-anxiety drug or a sedative, women are twice as likely to become addicted. In addition, statistics compiled for 12-17 year olds show that teenage girls are more likely than teenage boys to begin overusing psycho therapeutic medication such as painkillers, tranquillizers, stimulants and sedatives.

As the forceful king of Macedonia(马其顿), Alexander the Great overthrew the Persian Empire, becoming a hero that would survive centuries after his death.
Born in 356 B.C., Alexander III was the son of Philip II and Olympias. Alexander’s parents wanted him to receive the finest education, and arranged for him to study under Aristotle, regarded as one of the greatest scholars.
Alexander’s father was a strong leader. Philip II built an impressive army and established the Macedonian kingdom; he was even planning to attack Persia shortly before his death.
In 336, Philip was murdered by one of his guards. Although it was obvious that the guard had a personal hatred, there are clues that other people were related to it.
After Alexander was cleared as a suspect, he succeeded his father without opposition, and killed those said to be responsible for his father’s murder, as well as all rivals. He was then just 20 years old. He then prepared to attack Persia.
In the spring of 334, Alexander led the army made up of nearly 50,000 soldiers into Asia, which is called “the most powerful military expedition ever to leave Greece”, He soundly defeated the Persian army at the Granicus River, sending a strong message to Darius III, leader of the Persian Empire.
In 333, Alexander faced Darius at Issus, a mountain pass. The Macedonian army was greatly outnumbered but able to work the narrow mountain passageway to their advantage. Darius managed to escape. Continuing down the Mediterranean Coast, Alexander took every city in his path.
In 332 Alexander declared Egypt to be part of the Greek Empire and was crowned Pharaoh(法老).
When Alexander left Egypt in 331, he defeated the Persians again and was crowned leader of Asia.
In 323, however, Alexander developed a fever on the way back home and died 10 days later at Babylon. He was just 33 years old.

Jim suffered heart problems. In conversation he expressed little joy and it seemed that his life was drawing to a close.
When his heart problems led to operation, Jim went through it successfully, and a full recovery was expected. Within days, however, his heart was not beating properly. Jim was rushed back to operation, but nothing was found to explain the cause of his illness. He died on the operating table on the day before his 48th birthday.
Dr. Bruce Smoller, a psychologist (心理学家), had had many conversations with him, and the more he learned, the stranger he realized Jim's case was. When Jim was a child, his father, a teacher, suffered a heart attack and stayed home to recover. One morning Jim asked his father to look over his homework, promising to come home from school at noon to pick it up. His father agreed, but when Jim returned his father had died. Jim's father was 48.
"I think all his life Jim believed he killed his father," Dr. Smoller says. "He felt that if he had not asked him to look at his homework, his father would have lived. Jim had been troubled by the idea. The operation was the trial (判决) he had expected for forty years. " Smoller believes that Jim willed himself not to live to the age of 48.
Jim's case shows the powerful role that attitude (态度) plays in physical health, and that childhood experiences produce far-reaching effect on the health of grown-ups. Although most cases are less direct than Jim's, studies show that childhood events, besides genes, may well cause such midlife diseases as cancer, heart disease and mental illness.
Jim was sent back to operation because ________.
A. his heart didn't work well B. he expected a full recovery
C. his life was drawing to a close D. the first one wasn't well performed
What made Dr. Smoller feel strange about Jim's case?
A. Jim died at a young age.
B. Jim died on the operating table.
C. Both Jim and his father died of the same disease.
D. Jim's death is closely connected with his father's.
From Smoller's words, we can infer that ________.
A. Jim's father cared little about his study
B. Smoller agreed that Jim did kill his father
C. Jim thought he would be punished some day
D. Smoller believed Jim wouldn't live to the age of 48
Which of the following could have strong effect on one's physical health according to the text.?
