The painter Georgia O’keeffe was born in Wisconsin in 1887 and grew up on her family’s farm. At seventeen she decided she wanted to be an artist and left the farm for schools in Chicago and New York, but she never lost her bond with the land. Like most painters, O’Keeffe painted the things that were most important to her, and nearly all her works are simplified portrayals of nature.

O’Keeffe became famous when her paintings were discovered and exhibited in New York by the photographer Levered Stieglitz, whom she married in 1924. During a visit to New York in 1929, O’Keeffe was so moved by the bleak（荒凉的） landscape and broad skies of the Western desert that she began to paint its images. Cows’ skulls and other bleached（变白的） bones found in the desert figured prominently（突出的） in her paintings. When her husband died in 1946, she moved to New Mexico permanently and used the horizon lines of the desert, colorful flowers, rocks, barren(贫瘠的) hills, and the sky as subjects for her paintings. Although O’Keeffe painted her best known works in the 1920’s, 1930’s and 1940’s, she continued to produce tributes（贡品、颂词） to the Western desert until her death in 1986.

O’Keeffe is widely considered to have been a pioneering American modernist painter. While most early modern American artists were strongly influenced by European art, O’Keeffe’s position was more independent. She established her own vision and preferred to view her painting as a private endeavor. Almost from the beginning, her work was more indentifiably American than that of her contemporaries in its simplified and idealized treatment of color, light, space, and natural forms.

A cheap drug that can stop bleeding in people recently injured in an accident could potentially save the lives of tens of thousands worldwide, a new study says.

Researchers studied the effects of tranexamic acid （凝血酸）, or TXA, in more than 10,000 injured people in 40 countries who received the drug within 8 hours of being injured. The study was published in the medical journal Lancet. Doctors found that patients who got TXA had a 15percent lower chance of dying from hemorrhage than those who didn’t get it . They also had a 10 percent lower chance of dying from any other cause, including organ failure and a head injury. The study was paid for by the British government.

The drug is commonly used in wealthy countries during elective surgeries(外科手术) to stop bleeding , but isn’t used for accident victims. TXA is off-patent and made by many companies. It costs about $4.5 per gram, and a typical dose is two grams. It is usually given via an injection（注射） and would be relatively easy to introduce, even in poor countries, experts said.

Previous tests of the drug regarded its use in elective surgeries, such as heart operations, but this was the first study to test the drug on accident victims. Doctors were worried it might increase side effects such as blood clots （凝块）in the heart and lungs, strokes, or heart attacks. There was no evidence of that in the Lancet study, though the authors said it was possible they might have missed some of these incidents.

For people between 5 and 45, accidents are the second leading cause of death worldwide after AIDS, and about 600,000 injured patients bleed to death every year. Experts estimated that if TXA were readily available, between 70,000 and 100,000 lives a year could be saved. Though the drug wasn’t tested on children , experts said it would almost certainly work with them as well.

Diversity means the differences between things or people; the variety makes us unique.

People have a great deal of diversity. Even though our basic body structure is the same (head, eyes, heart, arms, legs, feet, etc.), our physical characteristics are different. For instance, the color of our skin, hair, and eyes are different. Also, our height and shape provide some diversity too. Even our fingerprints are unique and different.

People have to develop their own thoughts ,opinions, feelings, and ideas about different topics and beliefs.We are influenced by different people, places, and experiences in our lives which may influence us when we have to make a decision. A person has to keep open-minded when developing an opinion. Gathering information is also crucial（决定性的） to make a decision. The more you know about a topic, the easier it will be to make a good decision. As people grow up, they may even change their previous opinions and have new ideas.

Every person has unique talents, characteristics, and challenges to share with the world. Some people are good at reading and writing. Other people are talented at art and music. Some people are good at working with numbers or science. Others are talented by sharing their creativity. Some people have challenges to work with like being deaf, blind, or learning differently than others. It is important to remember that no matter what a person is good at or struggles with, we are all special in our own way.

When we are used to other people’s differences, we are showing respect. And we can find that we belong to the world and can give any thing a reason throughout the world. We can learn about a variety of cultures, places , and different ways to look at the world.
