With all of the wonderful things life brings us, it also brings us stress. It is for this reason that I am an active supporter of mental health days.

    Although it's never good to ignore(忽视) responsibilities, sometimes it is good to unplug(拔除) from the world for a day. We eat healthy and stay active to keep us from getting sick, but sometimes we forget to care for our minds. Our minds and bodies are connected, and when only one is being cared for, the other may be suffering. It is important to try to combine self care with our lives and spend time on activities we enjoy. This helps relieve stress on a daily day.

    So, what do you do on a mental health day? The answer is anything you want. Growing up, my brother and I were allowed a few mental health days a year. We would stay home from school and relax. For him, it was playing games on the computer, while my days were spent reading or watching TV. My mental health days now include picking things up around my apartment, cooking a tasty meal, and then reading for a few hours. I completely shut myself off from work or school. To me, this is relaxing. Organize the clutter(凌乱的东西) that piles up during the week, cook the meals I don't have time to cook, and read the books that I've bought but don't have time to read.

    A mental health day is great, but only if it's supplemented(增补) with self care through the week. From my experience, if self care is not regularly provided in your week, taking a mental health day is just going to stress you out even more. But when it's needed, try hard to recognize that and take care of yourself. It will help keep you happy and healthy. A mental health day is not a day to avoid life, it is a day to recoup(恢复).

    Most birds produce short, simple calls, but songbirds also have the ability of many complex vocal (发声的) patterns that help them attract mates, defend territory (领地), and strengthen their social bonds. Each songbird species has its own unique song patterns, some with characteristic regional dialects. Experienced listeners can even distinguish individual birds by their unique songs.

    A lot of what scientists know about bird song comes from studying zebra finches. A baby male zebra finch typically learns to sing from its father or other males, starting while it's still a baby bird in the nest. First comes the sensory learning stage, when the baby finch hears the songs sung around it and commits them to memory. The bird starts to vocalize during the motor learning stage, practicing until it can match the song it memorized. As the bird learns, hearing the tutor's song over and over again is helpful — up to a point. If it hears the song too many times, the imitation (模仿) becomes worse -- and the source matters. If the song is played through a loudspeaker, he can't pick it up as easily. But hide the same loudspeaker inside a toy painted to look like a zebra finch, and his learning improves.

    What if the baby never hears another zebra finch's song? Interestingly enough, it'll sing anyway. Isolated finches still produce what are called innate songs or isolate songs. A specific tune might be taught, but the instinct to sing seems to exist in a songbird's brain. Innate songs sound different from the “cultured” songs learned from other finches - at first. If isolate zebra finches start a new colony, the young birds pick up the isolate song from their fathers. But the song changes from generation to generation. And after a few generations, the melody actually starts to resemble the cultured songs sung by zebra finches in the wild.

    On June 23, 2010, a Sunny Airlines captain with 32 years of experience stopped his flight from departing. He was deeply concerned about a power part that might run out of all electrical power on his trans-Pacific flight. Regardless of his concerns, Sunny Airlines pressured him to fly the airplane over the ocean at night. When he refused to put the safety of his passengers at risk, Sunny Airlines' Security removed him out of the airport, and threatened to arrest his crew if they did not cooperate.

    Besides that, five more Sunny Airlines pilots also refused to fly the aircraft, expressing their own concerns about the safety of the plane. It turned out the pilots were right: the power part was faulty and the plane was removed from service and finally fixed. Eventually a third crew operated the flight, hours later. In this whole process, Sunny Airlines pressured their highly experienced pilots to ignore their safety concerns and fly passengers over the Pacific Ocean at night in a plane that needed maintenance. Fortunately for all of us, these pilots stood strong and would not be frightened.

    Don't just take our word. Please research this yourself and learn the facts at www.SunnyAirlinePilot.org. Once you review this shocking information, please keep in mind that while their use of Corporate Security to remove a pilot from the airport is a new procedure, flight crews' lacking confidence is becoming common at Sunny Airlines, with recorded events occurring on a weekly basis.

    The flying public deserves the highest levels of safety. No airlines should maximize their gains by pushing their employees to move their airplanes regardless of the potential human cost. Sunny Airlines' pilots are committed to resisting any practices of damaging your safety for profits. We've been trying to deal with these problems behind the scenes for quite some time; now we need your help. Go to www.SunnyAirlinePilot.org to get more information and find out what you can do.

Fire Prevention Information

    The University of Adelaide employs a full-time staff of fire prevention professionals. They inspect all campus buildings and test and maintain all sprinkler(喷水灭火装置）systems, fire alarms, and fire extinguishers (灭火器). They also provide educational programs or fire safety in the residence hall. Whenever you move to a new area, you should locate the fire alarm pull stations and the two exits nearest your room.

Fire Alarms

    The floors of all campus buildings are equipped with manual(手动的）fire alarm systems which include fire alarm pull stations and pipes. Most are also equipped with automatic fire alarm systems consisting of heat detectors, smoke detectors and sprinklers. For your safety, never tamper with(胡乱摆弄）these systems. False fire alarms are illegal and may lead to imprisonment.

Fire Drills

    A fire drill will be conducted in your residence hall every semester. During a fire drill, please do the following:

    •Take your room key and ID, close and lock the door to your room.

    •Exit immediately from the nearest emergency exit do not use a lift.

    •Meet outside of your residence hall and wait for further instructions.

Fire Extinguishers

    Fire extinguishers are located on each floor and in each apartment. Use a fire extinguisher only if you have been trained to do so. Irresponsible use of a fire extinguisher can create a dangerous situation for other residents and could result in damage to personal property. Misuse of a fire extinguisher will result in fines.

Smoke Detector

    A smoke detector is on the ceiling in your room. Some buildings also have heat detectors on the ceilings. Do the following to ensure the safe operation of your smoke detector:

    •If your smoke detector is working properly, the red light should be on. If the red light is not blinking（闪动），contact residence hall staff immediately.

    •Do not cover or block your smoke detector in any way.

    •If a smoke detector sets off an alarm and there is no fire or smoke, inform your hall staff.

    Forest Schools originated in Sweden in the 1950s and spread to other countries, particularly Denmark where they have become an important part of the Danish early years program.

    In a typical Danish Forest School, young children from 3 years are taken into the forest for 4 hours each day of the week. They take no toys with them, but instead use only what the forest provides (and their imaginations) to develop their games. There is a primitive hut in the forest, which is used in extreme weather. Activities are child-led and fun, such as finding small animals or stomping in puddles. Because of high adult to child ratios, children can safely try out activities which are often considered too dangerous, such as climbing trees or lighting fires, and by dressing the children in good protective clothing, they are able to play freely. By setting children small manageable tasks at which they are unlikely to fail, and giving genuine praise, children's independence and confidence grow.

    A Swedish scientific study found that children in the Forest School are more balanced and socially capable, have fewer sick days, are more able to concentrate and have better co-ordination than the city nursery children. The primary reason appeared to be the greater opportunities to play in nature, so that children play for longer at a time, tending not to disturb each other as much as children in the city nursery. The study observed that where children were interrupted, they became irritable, their stress level rose, and their ability to concentrate fell.

    The study also showed that the Forest School children had 25 % fewer sick days than the city children. One reason for this is that the air is nearly always better outside than indoors. Outside a child is not so exposed to virus and bacteria and not so likely to be infected by other children. Another reason may be that, since stress has been shown to have a negative effect on the immune system, high stress levels may be weakening the city children. The Forest School children, on the other hand, are in a pleasant, natural, fun and less stressful environment.

The Museum of Science and Industry

    The Manchester Museum of Science and Industry will give us a more wonderful interpretation of the museum. The 2.8 hectare museum was rebuilt on the site of a huge Victorian warehouse and the world's oldest passenger train station. The number and type of collections are ranked first, and in the power exhibition hall, steam engines used during the Industrial Revolution can still be seen. The display of the railway here is rich and vivid in content. Understanding the history of the Industrial Revolution, the Manchester Museum of Science and Industry is a good choice.

    Power is the central theme of the museum, whether it is a bicycle or a steam engine, not to mention an old car. The history of mankind, as this museum shows, has been constantly running. All human inventions can't be separated from this idea. Life is also about exercise. All the exhibits in the museum are alive. The workers oil and wipe every day. Finally, steam is imported into the machinery to make them run as usual as they did a hundred years ago. Time is also reversed.

    In the power exhibition hall, the steam engine that had been used during the Industrial Revolution was still roaring, and the influence was not reduced. If you want to understand the Industrial Revolution and the role of Manchester in it, you must come and visit it, and you will find answers from the many wonderful exhibitions here.

    The Manchester Museum of Science and Industry completely reproduced the British Industrial Revolution, and ensured that the machines of its scientific and technological inventions operated daily, so that visitors and school children could experience the Industrial Revolution. Therefore, the museum has become an outstanding model for preserving industrial heritage.

    Manchester was known as Cotton Capital, Northern Capital, Second City, and Warehouse City for the Industrial Revolution. The Manchester Museum of Science and Industry is located in the center of Manchester City. It records the cradle (摇篮) of the Industrial Revolution with historical details. Manchester City's history, textiles, energy, communications, aviation, transportation and other industries have risen and fallen with the development of science and technology.
