Singing of birds at her window awakened Lenore. The dawn streamed in bright and sweetly fragrant. The wheat-fields seemed a rosy gold, and all that open slope called to her thrillingly of the beauty of the world and the happiness of youth. It was not possible to be morbid at dawn. "I hear! I hear!" she whispered. "From a thousand slopes far and wide!"

At the breakfast-table, when there came opportunity, she looked up serenely and said, "Father, on second thought I will go the Bend, thank you!"

Anderson laid down his knife and fork and his eyes opened wide in surprise. "Changed your mind!" he exclaimed.

"That's a privilege I have, you know," she replied, calmly.

Mrs. Anderson appeared more anxious than surprised. "Daughter, don't go. That will be a fearful ride."

"Hum! Sure glad to have you, lass," added Anderson, with his keen eyes on her.

"Let me go, too," begged Rose.

Kathleen was solemnly gazing at Lenore, with the wise, penetrating eyes of extreme youth.

"Lenore, I'll bet you've got a new beau up there," she declared.

Lenore flushed scarlet. She was less angry with her little sister than with the incomprehensible fact of a playful word bringing the blood stingingly to her neck and face.

"Kitty, you forget your manners," she said, sharply.

"Kit is fresh. She's an awful child," added Rose, with a superior air.

"I didn't say a thing," cried Kathleen, hotly. "Lenore, if it isn't true, why'd you blush so red?"

input: Do you know Su Bingtian? He is a Chinese runner. He was born in Zhongshan City, Guangdong Province on August 20th, 1989. When he was a child, he liked running in the school running team. His parents supported him in practicing running and they often encouraged him to run. Though it's very hard for him to win every race, he never gives up. He tries his best to run well every day. He took part in the regular match in November, 2004 for the first time. After that, he won many first prizes in all kinds of matches. On May 31st, 2015, in Saturday's Eugene Grand Prix, the 1.72 meters-tall runner finished third in 9.99 seconds, behind American Tyson Gay in 9.88 seconds and Mike Rodgers in 9.90 seconds. Su Bingtian becomes beats 10-second barrier as the first Asian-born. China's Zhang Peimeng, who raced to his personal best of 10.00 seconds in 2013, is considered the closest to beating the barrier. Now Su Bingtian broke his record. "I am so proud of my result. I can write my name into history now and I will work harder and run faster," said Su Bingtian. Now let's congratulate to Su Bingtian! We hope Su Bingtian will have a better future and good luck to him! 1. Who beat Zhang Peimeng's record?

question: John was stuck in the middle of the ocean after his boat crashed and sank. He was worried about his friend who'd been in the boat with him. He knew that his friend has his life jacket on, so he tried not to worry too much about him. John was in a small box that fell out of the boat and kept him out of the water, floating. John had never been to sea before and one would wonder if he would ever after such a scary thing that happened to him. He sat in the box for days with no food or water, in and out of sleep. Three days later he woke up and saw land. Finally a beach was in sight, John could go home.

Q: Manganese is a chemical element with symbol Mn and atomic number 25. It is not found as a free element in nature; it is often found in minerals in combination with iron. Manganese is a metal with important industrial metal alloy uses, particularly in stainless steels.

Historically, manganese is named for pyrolusite and other black minerals from the region of Magnesia in Greece, which also gave its name to magnesium and the iron ore magnetite. By the mid-18th century, Swedish chemist Carl Wilhelm Scheele had used pyrolusite to produce chlorine. Scheele and others were aware that pyrolusite (now known to be manganese dioxide) contained a new element, but they were unable to isolate it. Johan Gottlieb Gahn was the first to isolate an impure sample of manganese metal in 1774, which he did by reducing the dioxide with carbon.

Manganese phosphating is used for rust and corrosion prevention on steel. Ionized manganese is used industrially as pigments of various colors, which depend on the oxidation state of the ions. The permanganates of alkali and alkaline earth metals are powerful oxidizers. Manganese dioxide is used as the cathode (electron acceptor) material in zinc-carbon and alkaline batteries.

In biology, manganese(II) ions function as cofactors for a large variety of enzymes with many functions. Manganese enzymes are particularly essential in detoxification of superoxide free radicals in organisms that must deal with elemental oxygen. Manganese also functions in the oxygen-evolving complex of photosynthetic plants. While the element is a required trace mineral for all known living organisms, it also acts as a neurotoxin in larger amounts. Especially through inhalation, it can cause manganism, a condition in mammals leading to neurological damage that is sometimes irreversible.

Answer the following questions:
1. What is the article about?
2. What is it used for?
3. How about in natural science?
A:
1. Manganese element
2. rust and corrosion prevention on steel
3. stainless steels.
