China has more than 30 intangible cultural heritage recognized by the UNESCO, including paper-cutting, the Dragon Boat Festival, Peking Opera, acupuncture(针灸)and so on. The organization adopted a decision that China's “The Twenty-Four Solar Terms” (二十四节气)should be put on the Representative List of the Intangible Cultural Heritage of Humanity in 2016 in Ethiopia.

    The Twenty-Four Solar Terms, knowledge of time and practices in agriculture, starts from the Beginning of Spring and ends with the Greater Cold, moving in cycles. It developed through the observation of the sun's annual movement in China. In ancient time, the method of tugui, earth sundial(日暑), was used to measure the shadow of the sun for determining the solar terms.

    The Twenty-Four Solar Terms came into being and developed in close relationship with Chinese agricultural production. At the initial stage of agricultural development, people began to explore the seasonal rules in the agricultural production to meet the needs in seeding, harvesting and other activities. Gradually, they formed the concept of “seed in spring, grow in summer, harvest in autumn and store in winter”. During the spring and autumn periods, the agricultural production was highly influenced by the seasonal changes, thus forming the concept of Solar Terms.

    As a traditional Chinese knowledge system of time with a history of thousands of years, the Twenty-Four Solar Terms clearly expresses the concepts of respect for nature, and harmony between man and nature. Created by Chinese ancestors, it have functioned as a complete set of weather calendar(日历)to guide the agricultural production in China. It has also been introduced into North Korea, Japan and other neighboring countries and still used in Japan. The Chinese heritage has provably influenced the people's way of thinking and behaving and will continue to be an important carrier of Chinese cultural identity.

    There are lots of insects that farmers hate. But there also are some they like. They protect crops against damage from other insects. A good example is the lady beetle, which is also known as the ladybug(瓢虫)．

    Lady beetles are a natural control for aphids(蚜虫). Lady beetles are red, orange or black. They often have black spots, though some have light colored spots. Different kinds of lady beetles have different numbers of spots. There are lady beetles with four, five, seven and fourteen spots.

    Many of the well-known kinds of lady beetles come from Asia or Europe. They now are common throughout the United States.

    American scientists imported one kind of lady beetle, the multicolored Asian lady beetle, as early as 1916. They released them as an attempt to control some kinds of insects. Over the years, the beetle has become established, possibly helped by some that arrived with imported plants on ships.

    Experts say over 450 kinds of lady beetles are found in North America. Some are native to the area. Others have been brought from other places. Almost all are helpful to farmers.

    The Asian lady beetles now in the United States probably came from Japan. The Asian lady beetle eats aphids that damage crops like soybeans, fruits and berries.

    In the southern United States, Asian lady beetles have reduced the need for farmers to use reskilling poisons on pecan trees. This popular tree nut suffers from aphids and other pests that the lady beetles eat.

    But some people say the Asian lady beetle has itself become a pest. They worry that the lady beetles may eat their late autumn fruit crops.

    Experts say Asian lady beetles may appear in large numbers in some years. But they say the insects are too helpful to be considered as pests.

    I serve as an educator and health care provider as well, therefore, I have worked with numerous children infected with the virus that causes AIDS. The relationships that I have had with these special kids have been gifts in my life. They have taught me so many things, but I have especially learned that great courage can be found in the smallest of packages. Let me tell you about Tyler.

    Tyler was born infected with HIV: his mother was also infected.From the very beginning of his life, he was dependent on medications to enable him to survive.When he was five, he had a tube surgically inserted in a vein in his chest.This tube was connected to a pump, which he carried in a small backpack on his back. Medications were hooked up to this pump and were continuously supplied through this tube to his bloodstream.At times, he also needed supplemented oxygen to support his breathing.

    Tyler wasn't willing to give up one single moment of his childhood to this deadly disease.It was not unusual to find him playing and racing around his backyard, wearing his medicine-laden backpack and dragging his tank of oxygen behind him in his little wagon.All of us who knew Tyler marveled at his pure joy in being alive and the energy it gave him.Tyler's mom often teased him by telling him that he moved so fast that she needed to dress him in red.That way, when she peered through the window to check on him playing in the yard, she could quickly spot him.

    This dreaded disease eventually wore down even the likes of a little dynamo (精力充沛的人) like Tyler. He grew quite ill and, unfortunately, so did his HIV-infected mother.When it became apparent that he wasn't going to survive, Tyler's mom talked to him about death.She comforted him by telling Tyler that she was dying too, and that she would be with him soon in heaven.

    A few days before his death, Tyler beckoned me over to his hospital bed and whispered, “I might die soon.I'm not scared.When I die, please dress me in red.Mom promised she's coming to heaven, too.I'll be playing when she gets there, and I want to make sure she can find me.”

    Asking a patient to hum(哼唱)piano tunes and play fin instrument while undergoing brain surgery(手术)may sound like a strange request from a doctor．However，that is exactly what a team of brain specialists，led by Pilcher，requested Dan Fabbio to do．

    In 2015，the then 25-year-old musician was diagnosed with a brain tumor(肿瘤)，which was located in the part of the brain known to be active when people listen to and make music．“Removing a tumor from the brain can have significant consequences depending on its location，”Pilcher says．“Both the tumor and the operation can damage tissue and affect communication between different parts of the brain．”

    Fabbio，therefore，feared the surgery would cause him to lose his musical ability．To prevent that from happening，Pilcher and his colleague designed many tests，including asking Fabbio to listen to piano tunes and hum back during MRI scans．This enabled the physicians to locate the area that is vital for music and language processing and create a 3-D map of Fabbio's brain．

    Despite the great starting point，it was not a perfect way to prevent possible damage to the．The only way was to keep the patient awake and ask him to hum piano tunes during the surgery so that the surgeons could identify the areas to avoid．While the surgery went smoothly，the real test came when Fabbio was asked to play a song on his saxophone．The tunehad been simplified to ensure that it would not require too much strength and cause harm to the stitches(缝线)in the brain．He played it faultlessly，and when he finished，the entire operating room erupted in applause．

    The researchers say that a year after the groundbreaking surgery，the young musician can once again hear tunes in everything—even his electric toothbrush．

    He looked like a pirate.

    With his handkerchief tied in a knot behind his little nine-year-old head, he looked like a pirate, a sad pirate. The first time little David came to our camp, he was hairless and worn out from medical treatments. He was also very angry.

    Paul Newman's camp counselors (指导老师) were hoping to fill David's days with fun and laughter. But David stayed inside himself, wanting to be alone, or in a corner of the cabin. At this camp for children with life-threatening illnesses, we had seen some pretty tough children worn out by cancer recover full of energy despite their illness. But we saw little progress in David no matter what we tried with him. Five days into the eight-day session saw a quiet, sad little pirate.

    Then something happened on that fifth night. Something at camp that we would call "huge". It was cabin night. That's the time when campers and counselors spend time together in each individual cabin instead of an all-camp activity. Campers love cabin nights because there's always a bedtime snack. On the cabin table that night were bags of potato chips.

    David slowly walked over to the table, leaving his comer to join the rest of us. He took one of the bags of the potato chips and started smashing(弄碎) it with his little fists, as all the other campers looked on in disbelief, I wondered what the cabin counselor would do.

    The college-age volunteer counselor positioned a bag of chips on die table in front of himself, and he, too, started smashing it with his fist. The campers went crazy as everyone ran to the table to get in on the fun of smashing potato chips with their fists.

    Somehow everyone knew, everyone sensed, that anger within him was now being released.

    For the last couple days of the session, David was a different kid. He was a little nine-year-old boy again, trying to fill the hours of each remaining day at camp with as much fun as could be possible.

    Several days after the session, David came back again. This time, there wasn't anything he wouldn't try to fit in to his day. He sure was having a great time at camp. David asked me if I needed an altar(祭坛)boy when I celebrated Mass in the woods. Sure enough, he was my altar boy. I remembered how carefully he listened to me when I talked about death. I said it's only a doorway. You walk through the door and there's the Lord God and behind God a whole line of people waiting to hug you.

    After Mass, he said to me, "Hey Fatha, a door, huh?"

    A couple more days of fun passed and tonight was the talent show. The tradition is that campers and counselors dress up in costumes, and everyone gets a standing applause for singing and dancing or simply just acting like fools on stage.

    The show had begun: lights, camera, action.

    Unfortunately, the only action taking place in our row of seats was little David making his way from counselor to counselor to say an early good-bye to camp. He had become quite ill and had to go to the hospital because of this new crisis.

    When this little nine-year-old pirate stood in front of me, he gave me a hug and a big wet kiss on my cheek. I was crying. He was crying. A whole row of counselors was in tears. After the hug and kiss, he put his hands on my shoulders, and tears still in his eyes, said: "See you on the other side of the door, Fatha."

    Homesick is a compound word made up of HOME and SICK. You know what each word means on its own, of course. But think about what the words mean when they are used together. Homesick means SICK FOR HOME.

    Now think for a minute about SEASICK. If you change the word home in the definition(释义)to the word sea, would the definition fit SEASICK? Seasick means SICK BY THE MOVEMENT ON THE SEA. When you are homesick, the only place you want to be is at home. When you are seasick, the last place you want to be is at sea.

    Have you ever heard of a person being heartsick? Heartsick doesn't mean that something is wrong with a person's heart, people are heartsick when they are hurt deep inside and when they feel as if their hearts are broken.

    But, on the other hand, we have such compound words as handshake, handstand, and handbag. Perhaps you may write definitions for them.
