    Daban town is famous for girls and windmills, while Loulan is a myth (神话) in the desert. Two thousand years ago, beside the beautiful Luobu Lake, there lay Loulan ancient city of the Silk Road. Businessmen from every country gathered there with lots of dancing parities. Everything shows that people in Loulan lived a rich life then.

    However, two thousand years later, this rich land suddenly disappeared from the map of China. It became an area covered with sand and dead tree trunks.

    Loulan was first "discovered" by a Swedish man named Sven Hedin in 1900, and people from America, Britain, Japan and Sweden all set foot here. Then in the 1930s, a Chinese named Huang Wenbi came to Loulan for the first time. He visited and studied this area and found many relics that were beautifully and carefully made.

    It is recorded that the ancient city of Loulan was the capital of the Loulan Kingdom during the Han and Jin Dynasties, and covered an area of some 10, 000 square kilometres. Inside the city, there are the ruins of government offices, temples and other old buildings. Outside the city there are some dried-up rivers and much farmland. In the past century many things have been dug up there including Han Dynasty coins, mirrors and many others of Greek and Roman times. All these things show that a lot of business between the East and the West once took place there.

    Lying on the northwest of the Lop Nur area, the Loulan Kingdom is now a lifeless area with endless ＂forests＂ of mounds (小丘) which aren't easily seen in other parts of the world. Its mystery has been attracting many people from many countries.

    Honey from the African forest is not only a kind of natural sugar, it is also delicious. Most people, and many animals, like eating it. However, the only way for them to get that honey is to find a wild bees nest(巢）and take the honey from it. Often, these nests are high up in trees, and it is difficult to find them. In parts of Africa, though, people and animals looking for honey have a strange unexpected helper—a little bird called a honey guide.

    The honey guide does not actually like honey, but it does like the wax（蜂蜡） in the beehives (蜂房).

    The little bird cannot reach this wax, which is deep inside the bees' nest. So, when it finds a suitable nest, it looks for someone to help it. The honey guide gives a loud cry that attracts the attention of both passing animals and people. Once it has their attention, it flies through the forest, waiting from time to time for the curious animal or person as it leads them to the nest.

    When they finally arrive at the nest, the follower reaches in to get at the delicious honey as the bird patiently waits and watches. Some of the honey and the wax，always falls to the ground, and this is when the honey guide takes its share.

    Scientists do not know why the honey guide likes eating the wax, but it is very determined in its efforts to get it. The birds seem to be able to smell wax from a long distance away. They will quickly arrive whenever a beekeeper is taking honey from his beehives, and will even enter churches when beeswax candles are being lit.

    At a daycare center in Texas, children were playing outside. One of the children was Jessica Mc Clure. She was 18 months old. Her mother, who worked at the daycare center, was watching the children. Suddenly Jessica fell and disappeared. Jessica's mother screamed and ran to her.

    A well was in the yard of the center. The well was only eight inches across and a rock always covered it. But children had moved the rock. When Jessica fell, she fell right into the well.

    Jessica's mother reached inside the well, but she couldn't feel Jessica. She dialed 911 for help. Men from the fire department arrived. They discovered that Jessica was about 20 feet down in the well. For the next hour the men talked and planned Jessica's rescue.

    "We can't go down into the well," they said."It's too narrow. So, we're going to drill a hole next to the well. Then we'll drill a tunnel across to Jessica. When we reach her, we'll bring her through the tunnel and up through our hole."

    The men began to drill the hole at 11 a.m. on Wednesday, October 14, 1987. The men had a difficult job; they were drilling through solid rock. During her days in the well, Jessica sometimes asked for her mother. Sometimes she slept, sometimes she cried and sometimes she sang.

    All over the world, people waited for news of Jessica. Everyone worried about her.

At 8 p.m. on Friday, October 16, men reached Jessica and brought her up from the well. She was soon sent to hospital. Jessica was dirty, hungry, thirsty and tired. Her feet and forehead were badly injured. But Jessica was alive.

    After Jessica's rescue, one of the rescuers made a metal cover for the well, saying," To Jessica, with love from all of us."

    The United States of America is mainly an English-speaking country. The majority of the population speak English as their native language. Besides, education, social activities, etc. are conducted in English. Across but for the most part, Americans speak one common language. This language is sometimes called American English.

    However, not everyone in the USA is a native speaker of English. Most immigrants (移民)are speakers of other languages. There are hundreds of communities around the USA where English is not the most commonly used languages. Chinese, Italian, German, Greek, Spanish and French are all spoken in various communities in the USA. Spanish is the second most commonly spoken language after English. It is widely spoken in New York and across the southern part of the country. For speakers of other languages, learning English is important, but teaching people to speak English as a second language was given little attention. Non-English speakers were expected to "pick up" the language by meeting with others in public. Recently, this has changed.

    Today, most large public schools and community colleges have ESL(English as a Second Language )programs; American English teachers feel that English students should learn the language the way they will use it. Therefore, ESL programs offer different English lessons to different students. Some programs teach students to communicate in English in public. Other programs teach the kind of English people who will need for their jobs. American ESL instructional methods do not lay emphasis on grammar or translation, but on the importance of communication. The goal is to get the English learners to learn by using the language.

    Microsoft announced this week that its facial-recognition system is now more accurate in identifying people of color, touting (吹嘘)its progress at tackling one of the technology's biggest biases (偏见).

    But critics, citing Microsoft's work with Immigration and Customs Enforcement, quickly seized on how that improved technology might be used. The agency contracts with Microsoft for cloud-computing tools that the tech giant says is largely limited to office work but can also include face recognition.

    Columbia University professor Alondra Nelson tweeted, "We must stop confusing 'inclusion' in more 'diverse' surveillance (监管)systems with justice and equality."

    Facial-recognition systems more often misidentify people of color because of a long-running data problem: The massive sets of facial images they train on skew heavily toward white men. A Massachusetts Institute of Technology study this year of the face-recognition systems designed by Microsoft, IBM and the China-based Face++ found that facial-recognition systems consistently giving the wrong gender for famous women of color including Oprah Winfrey, Serena Williams, Michelle Obama and Shirley Chisholm, the first black female member of Congress.

    The companies have responded in recent months by pouring many more photos into the mix, hoping to train the systems to better tell the differences among more than just white faces. IBM said Wednesday it used 1 million facial images, taken from the photo-sharing site Flickr, to build the "world's largest facial data-set" which it will release publicly for other companies to use.

    IBM and Microsoft say that allowed its systems to recognize gender and skin tone with much more precision. Microsoft said its improved system reduced the error rates for darker-skinned men and women by "up to 20 times," and reduced error rates for all women by nine times.

    Those improvements were heralded(宣布)by some for taking aim at the prejudices in a rapidly spreading technology, including potentially reducing the kinds of false positives that could lead police officers misidentify a criminal suspect.

    But others suggested that the technology's increasing accuracy could also make it more marketable. The system should be accurate, "but that's just the beginning, not the end, of their ethical obligation," said David Robinson, managing director of the think tank Upturn.

    At the center of that debate is Microsoft, whose multimillion-dollar contracts with ICE came under fire amid the agency's separation of migrant parents and children at the Mexican border.

    In an open letter to Microsoft chief executive Satya Nadella urging the company to cancel that contract, Microsoft workers pointed to a company blog post in January that said Azure Government would help ICE "accelerate recognition and identification." "We believe that Microsoft must take an ethical stand, and put children and families above profits," the letter said.

    A Microsoft spokesman, pointing to a statement last week from Nadella, said the company's "current cloud engagement" with ICE supports relatively anodyne(温和的)office work such as "mail, calendar, massaging and document management workloads." The company said in a statement that its facial-recognition improvements are "part of our going work to address the industry-wide and societal issues on bias."

    Criticism of face recognition will probably expand as the technology finds its way into more arenas, including airports, stores and schools. The Orlando police department said this week that it would not renew its use of Amazon. com's Rekognition system.

    Companies "have to acknowledge their moral involvement in the downstream use of their technology,"

    Robinson said. "The impulse is that they're going to put a product out there and wash their hands of the consequences. That's unacceptable."

Throughout our lives,we have been told to take care of our physical health.But what is often ignored is mental health.That's why World Mental Health Day was created.{#blank#}1{#/blank#}.

When is World Mental Health Day?

World Mental Health Day is on October 10th.Though there is one specific date for it,it is often times celebrated and observed over the course of a week.{#blank#}2{#/blank#}, it allows more people to know about the importance of mental health and it educates the public about the "why", "how" and "what" of mental health.

What is the history of World Mental Health Day?

{#blank#}3{#/blank#}.When it first started,the day had no theme,but instead was an excuse for medical workers to educate the public on what was not always openly discussed — what mental health is and the issues that surround it.Mental health affects everything from our emotional state to our physical state,and everything in between.In the first few years,organizers usually hosted a global live broadcast,leading to live telephone participation from all over the world.
