Whether it’s a carol（圣诞颂歌）service or an evening of karaoke in the pub, many people will enjoy a good old singsong this Christmas. Singing aloud will not just lift the spirits---it’s good for your physical health as well. Filling the lungs（肺）with air, increasing the heart rate and getting blood pumping round the body faster can all help our physical health.
For the past few years Heart Research UK has been Funding a Christmas campaign aimed at getting people singing, simply for the benefit it can bring. The organizer of the campaign says singing is a safe, simple and social activity that everyone can enjoy. “Singing is linked to long life, stress reduction, and general health protection. It also brings a great amount of happiness. It is impossible to sing well with a long face because it affects your pitch（音高）.”
Professor Graham Welch, who leads the International Music Education Research Centre at the University of London, has spent more than 30 years studying the effects of singing. He says that singing is a form of exercise. It means we’re also having a strong aerobic activity（有氧运动）when we’re singing, which results in increasing the feeling of pleasure while decreasing that of stress.
“And communal（共同的）singing—like in a singing group, a church service or even a singsong in the pub—helps improve our sense of self-respect. It increases our sense of satisfaction with ourselves, a greater sense of feeling included. ”
Helen Astrid, a singing teacher, also sees the great effects that singing brings. “It lifts us up on a spiritual level, it helps our self-respect, and it’s great for all ages from small kids to grannies—you can have a good sing and let your hair down.”
But she warns people not to have too many beers or glasses of wine, though a glass may help them gather courage before taking to the stage during the holidays.

When middle-aged Alex quit his job and made up his mind to become a self-employed writer, no one could tell for sure whether he would succeed or not．He found a cold storage room in a building, set up a used typewriter and settled down to work．
After a year or so, however, Alex began to doubt himself．He found it was difficult to earn his living by selling what he wrote．But Alex determined to put his dream to the test—even though it meant living with uncertainty and fear of failure．This is the shadowland（虚幻世界）of hope, and anyone with a dream must learn to live there．
One day Alex got a call, "We need an assistant, and we’re paying $ 6,000 a year．” $ 6,000 was real money in 1960．It would enable Alex to get a nice apartment, a used car and more．Besides, he could write in his spare time．As the dollars were dancing in Alex’s head, something cleared his senses．He had dreamed of being a writer? Full time．"Thanks, but no," Alex said firmly and swiftly, "I’m going to stick it out and write．"
After Alex got off the phone, he pulled out everything he had: two cans of vegetables and 18 cents．Alex put the cans and cents into a paper bag, saying to himself," There’s everything you’ve made of yourself so far．I’m not sure I ever felt so low．"
Finally his work was published in 1970．Instantly he had the kind of fame and success that few writers ever experienced．The shadows had turned into focus of attention．
Then one day, Alex found a box filled with things he had owned years before．Inside was a paper bag with two cans and 18 cents．Suddenly he pictured himself working in that cold storage room．It reminds Alex, and anyone with a dream, of the courage and persistence it takes to stay the course in the shadowland．
【小题1】Why did Alex give up his job?

A lazy Susan is an addition to a table, which is designed to assist in moving food from one person to another while dining. This is accomplished through the use of a turntable(转盘), which usually moves the food in a circle when pushed by those at table. In this way, the food never has to be picked up and passed around the table. Instead, it remains in place as the lazy Susan is turned about.
A lazy Susan may also be a part of a kitchen cabinet. One may spin the lazy Susan in order to find certain goods stored in it. From the outside, a lazy Susan appears to be two cabinets. When one of these cabinets is pushed, however, both doors move and the lazy Susan is revealed inside.
Whether the lazy Susan is on a tabletop or within a cabinet, it can be made of a variety of materials. Most commonly, a lazy Susan is made of either plastic, wood or glass. Some people believe that Thomas Jefferson invented the lazy Susan, though it was referred to as a dumb waiter(上菜升降架) at that time. It is said that Jefferson invented the lazy Susan because his daughter complained she was always served last at table and, as a result, never found herself full when leaving the table. Others believe that Thomas Edison was the inventor, as he is believed to have invented the turntable for his phonograph(留声机), which later developed into the lazy Susan.
Regardless of who invented it, it wasn’t until 1917 that the term lazy Susan was created in an advertisement for the invention. In Britain, however, the term dumb waiter is still used rather than the term lazy Susan. The reason for the name lazy Susan remains a mystery. One theory is that it was named after either Jefferson’s or Edison’s daughter, both of whom were named Susan.

【小题1】Why did Alex give up his job?

When JetBlue captain Clayton Osbon became unpredictable, his co-pilot invented a reason for him to go back into the cabin．Once the captain was out of the cockpit （驾驶舱） , the co-pilot locked the door to keep the captain from returning．Passengers, some with law enforcement experience, calmed the captain．The flight changed course to Amarillo, Texas where the captain was hospitalized．
Incidents in which a pilot has had an in-flight psychological breakdown are rare．But how could it happen at all? Though pilots are required to have an examination at least once a year by a physician approved by the FAA, there are no formal procedures in place to test pilots for signs of psychological problems．
At most airlines, pilots are members of a union．A pilot who appears to have a psychological or an alcohol problem can be reported to a union member whose job it is to investigate．If there is a problem, the pilot is given the choice of getting treatment or being reported to management．But at airlines, such as Allegiant, JetBlue, and Virgin American where there is no union, pilots are – to say the least - unwilling to report a fellow pilot to management．
In most professions, a person experiencing emotional difficulties is free to consult a doctor．Rut an airline pilot in therapy is viewed with suspicion both by the airline and by the FAA．No pilot wants to be put under extra examination by an agency that has the power to revoke their license or end their employment．That being the case, pilots are less likely than people in other professions to seek help．
There may be no way to make sure this never happens again, but its possibility can be reduced． Tests such as the Minnesota Multiphasic Personality Inventory （ MMPI） can reliably detect depression, paranoia, schizophrenia, and other problems．The FAA could require pilots to take the MMPI or a similar test on a periodic basis．Whether such testing becomes required will depend upon the public's response to this incident and whether additional incidents take place．
Flying is remarkably safe．But incidents such as this cause concern．
