Nearly 19 percent of teachers of color (有色人种教师) left their jobs after the 2014-2015 school year. Some left for personal reasons like taking care of their families. But 50 percent said they left because they were dissatisfied with their employment situation, such as poor working conditions, student discipline problems and large class sizes. Thus, taking immediate measures to improve it is our top priority.

    For years, researchers have proved the benefits of increasing the share of minority teachers in schools, especially as our public school system has turned to one that is made up mostly of minority students. Teachers of color, who are more likely than their white counterparts to choose to work in racially diverse (多种多样的) schools, offer particular benefits to their students. Graduation rates increase among minority students when they are taught by racially similar educators, research shows. They can also serve as positive role models, and their presence reduces the chance of racial discrimination at school.

    The Shanker Institute report suggests that the rate of minority teacher hiring is not the whole problem. The problem is what happens after these teachers enter the classroom. These teachers often work in high-poverty rural schools. They are more likely to have less-desirable working conditions.

    Diversity is a key component to equality and opportunity. Where there's a diverse teaching workforce, all kids thrive. So solutions must be found at once to turn this trend around. Firstly, schools should develop mentorship programs that support minority teachers once they are in the classroom. Secondly, more money should be spent in improving working conditions in these schools. Of course, school headmasters should also be evaluated on their ability to retain teachers of color.

    In the depths of the French Guianese rainforest, there still remain unusual groups of (土著的）people. Surprisingly, these people live largely by their own Laws and their own social customs. And yet, people in this area are in fact French citizens because it has been a colony of the French Republic since 1946. In theory，they should live by the French law. However, their remote locations mean that the French law is often ignored or unknown, thus making them into an interesting area of “lawlessness” in the world.

    The lives of these people have finally been recorded thanks to the effects of a Frenchman form Paris called Gin. Gin spent five months in early 2015 exploring the most remote comers of thin area, which sits on the edge of the Amazon rainforest, with half its population of only 250,000 living in its capital, Cayenne.

    “I have a special love for the French Guianese people. I have worked there on and off for almost ten years," says Gin. "I've been able to keep firm friendships with them. Thus I have been allowed to gain access to their living environment. I don't see it as a lawless Und. But rather I Me it as an area of freedom."

    “I wanted to show the audience a photographic record touching upon the uncivilized life," continues Gin. “I prefer to work in black and white, which allows me to show different specific worlds more clearly.”

    His black-and-white pictures present a world almost lost in time. These pictures show people seemingly pushed into a world that they were unprepared for. These local citizens now have to balance their traditional self-supporting hunting lifestyle with the lifestyle offered by the modern French Republic, which bring with it not only necessary state welfare, but also alcoholism, betrayal and even suicide.

    Consider the tomato: easy to grow, healthy to eat, tasty in just about any dish and pleasant to look at. And come late summer, in steady supply. Though you can find it during the coldest winter months.

    August is the tomato's season to shine. Farmers' markets and stores are bursting with less known but tastier varieties, including purple cherries and big heirlooms.

    "Heirlooms ripened on the vine(藤) are the tastiest of all tomatoes," says Amy Goldman Fowler, author of The Heirloom Tomato. "I think their beauty is more than skin-deep." Heirloom seeds have been around for at least 50 years, often passed down from generation to generation. You may hear cherry or heirloom used to describe a tomato at hand, but there are many different kinds of tomatoes, and growers have fun giving fancy names to varieties: Mortgage Lifters, Beefsteaks, Oxhearts, Early Girls.

    And all of them come with health benefits. Tomatoes are a good source of the antioxidant lycopene (抗氧化番茄红素), which is thought to help lower a person's risk for heart problems and cancer. Tomatoes also contain healthy vitamins A and C. For the best fruit, choose tomatoes with shiny, firm skin and a little give, and store them at room temperature away from direct sunlight. Keep them out of the fridge, since cold temperatures can affect the original taste.

    "They satisfy something more than just taste," says Fowler. "Tomatoes feed your soul."

    If you think American cooking means opening a package and throwing the contents into the microwave oven (微波炉), think again. On the one hand, it's true that many Americans have cold cereal for breakfast, sandwiches for lunch and instant (方便的) dinners. From busy homemakers to working people, many Americans enjoy the convenience of fast food that can be ready to serve in 10 minutes or less. On the other hand, many Americans realize the importance of cooking skills. Parents—especially mothers'—see the importance of training their children—especially daughter's. Most Americans think that there's nothing better than a good home-cooked meal. But with cooking, as with any other skill, good results don't happen by accident.

    Probably every cook has his or her own way of cooking. But there are some basic skills that most people follow. For example, baking is a main method of preparing food in America. For that reason, Americans would find it next to impossible to live without an oven. American cooks pay special attention to the balance of foods, too. In planning a big meal, they try to include meat, a few vegetables, some bread and often a dessert. They also like to make sure the meal is colorful. Having several different colors of food on the plate usually makes for a healthy meal.

    For those who need guidance in their cooking, or for those who have just run out of ideas, recipes are a great help. Recipes list all the ingredients for a dish (generally in the order used), the amount of each to use, and a description of how to put them together.

Anew study suggests that Medicare could spend billions of dollars on screening (拍片检查) smokers for lung cancer that would be better spent on helping them quit and keeping others from starting.

The new study indicated that screening more often supported smokers' beliefs that they could safely continue to smoke. Most participants remained smoking because they believed screening could catch cancer early before it would threaten their lives.

"They compared how hard it was to quit smoking with how easy it was to be screened," said Steven B. Zeliadt, the lead author of the study." They engaged in magical thinking that now there's this wonderful painless external test that can save lives."

He and seven colleagues conducted the study of 37 current smokers who were offered lung cancer screening at Department of Veteran Affairs. After being screened and told the results, they were interviewed about their smoking-related heath beliefs. For about half of those, cancer was not found." Screening lowered their motivation for quitting," the team reported in July in JAMA Internal Medicine. The participants focused only on lung cancer, ignoring other potential harm of smoking.

A national study published four years ago found that annual CT screening for lung cancer three years in a row could reduce deaths among heavy smokers by about 20 percent. In an interview, Dr. Russell P. Harris, a preventive medicine specialist at the UNC-Chapel Hill, noted that" Screening is being believed by people as an alternative to stopping smoking. But stopping smoking would have huge benefits for the individual and society." Furthermore, smoking causes many other cancers.

Dr. Harris agreed that rather than screening, money is better spent on smoking prevention. He suggested providing free stop-smoking aids, sponsoring anti-smoking advertising and raising taxes on tobacco products and the age at which people are allowed to buy them.

A boy who has been climbing the equivalent（等量）of Mount Qomolangma in aid of a children's hospice（救济院）is about to reach his fundraising goal of £29,031. Six-year-old Oscar, from Lancaster, has climbed 10 of the UK's highest mountains to help Chorley's Derian House. He said he needed two more to match Mount Qomolangma's 29,031 feet height.

Oscar started his challenge on October 9, 2022, and Ingleborough in the Yorkshire Dales was the first mountain to be chosen. He said that the hardest climb so far had been Cairn Gorm in the Scottish Highlands because the snow was so deep.

Oscar took on the challenge in the hope of raising enough money to send 29 children with life-limiting illnesses on holiday. "I wanted to be the youngest person to climb Mount Qomolangma and I have climbed 10 out of 12 mountains. When I get older, I want to climb the real Mount Qomolangma," Oscar said.

"It was amazing what a child's dream can achieve. We're speechless and couldn't be prouder. We were grateful to everyone that supported us along Oscar's journey," Oscar's father Matt wrote on the social media.

Oscar and his family hoped to make their final climb on Ben Nevis in Scotland on May 29, 2023. The climb would mark not only the completion of Oscar's challenge, but also the 70th anniversary of the first successful ascent（攀登）of Mount Qomolangma by Edmund Hillary and Tenzing Norgay.

"For every foot he climbed, our children would get a pound to achieve their dreams. The total £29,031 raised by Oscar would help support the work of the hospice, which provides end-of-life care to more than 400 children across the northwest of England," said Karen Edwards, a senior official of Derian House.

"The six-year-old was an unbelievable little boy who had truly gone to great heights. How many six-year-olds could say that they have climbed the height of Mount Qomolangma?" Karen added.
