It's true to say that technology makes our lives easier. However, increasingly scientists are saying that we need to give ourselves a break—--otherwise we put ourselves at risk(风险) of developing hundreds of health problems. Over the summer the days are longer and sunnier. Why not put this free time to good use and do something away from technology?

    You could learn a new skill. There are hundreds of possibilities: cooking, a musical instrument or a new sport. Haven't you always wanted to learn how to knit(编织)? You could use your free time to practice these new things, which might lead to an exciting opportunity in the future.

    If you just want to relax, why not head to a beach? Take along your favorite book and relax on the sand, or go for a walk along the coastline. If you don't live near a beach, you could go to your local park. Why not have a picnic, or try to explore some of the local wildlife? You could even get involved in the latest craze(狂热): adult coloring books! Coloring is a surprising thing to help you relax, and it can be a nice way to escape from the stress of modern life!

    Whatever you choose to do, try something new! You might surprise yourself and find a hidden gift within you; you might make new friends along the way. Next time you find yourself changing TV channels(频道) from one to another without a clear purpose, think about what else you could spend your time doing.

    Our lifestyles today are very busy. We have family, school, sports, entertainment and social activities to fit into a time that seems never enough. We need to be healthy to meet the demands of daily life. But what does it mean to have a healthy lifestyle?

To have a healthy lifestyle, we need to:

◆ eat different kinds of healthy food most of the time

◆ do exercise often

◆ have time to relax

◆ get enough sleep to give our bodies time to grow healthy and strong

Read about a normal day in the lives of two children.

    No matter which kind of lifestyle you agree on, just remember it's important to balance all aspects of life.

    New research, attempting to throw light upon how male and female brains differ, has found that timing is everything. American Vanderbilt University researchers Stephen Camarata and Richard Woodcock discovered that females have a significant advantage over males in timed tests and tasks. The study involved more than 8,000 males and females ranging in age from 2 to 90 from across the US.

    “We found hardly any differences in overall intelligence. But we discovered that females performed better than men in time limited situations,” Camarata said, “It is very important for teachers to understand this difference in males and females when it comes to assigning work and tests.”

    Many males can do a better job without strict time limits, added Camarata.

    “Consider that many classroom activities, including testing, are directly or indirectly related to processing speed,” the researchers wrote in their report. “The higher performance in females may contribute to a classroom culture that favors females, not because of teacher bias(偏见)but because of inherent(与生俱来的)differences in gender processing speeds.”

    The researchers found that males scored lower than females in all age groups in tests measuring processing speed. However, the study also found that males consistently outperformed females in some language abilities, such as identifying objects and knowing antonyms(反义词)and synonyms(同义词). The research contradicts the popular belief that girls develop all communication skills earlier than boys.

    The researchers found no significant overall intelligence differences between males and females in any age groups.

    “We believe there are fundamental differences in how male and female brains end up getting organized,” Camarata said, “Our next studies will give us some insight into where these processing differences are occurring.”

    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 on fire safety in the residence halls. 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 Detectors

    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.

    I had an experience some years ago, which taught me something about the ways in which people make a bad situation worse by blaming themselves. One January, I had to hold two funerals for two elderly women in my community. Both had died "full of years", as the Bible would say. Their homes happened to be near each other, so I paid condolence(吊唁) calls on the two families on the same afternoon.

    At the first home, the son of the deceased(过世的)woman said to me, "If only I had sent my mother to Florida and gotten her out of this cold and snow, she would be alive today. It's my fault that she died." At the second home, the son of the other deceased woman said, "If only I hadn't insisted on my mother's going to Florida, she would be alive today. That long airplane ride, the sudden change of climate, was more than she could take. It's my fault that she's dead."

    You see that any time there is a death, the survivors will feel guilty. Because the course of action they took turned out bad, they believe that the opposite course—keeping Mother at home, putting off the operation—would have turned out better. After all, how could it have turned out any worse?

    There seem to be two elements involved in our willingness to feel guilty. The first is our need to believe that the world makes sense, that there is a cause for every effect and a reason for everything that happens. That leads us to find patterns and connections both where they really exist and where they exist only in our minds.

    The second element is the view that we are the cause of what happens, especially the bad things that happen. It seems to be a short step from believing that every event has a cause to believing that every disaster is our fault. The roots of this feeling may lie in our childhood.

    A baby comes to think that the world exists to meet his needs, and that he makes everything happen in it. He wakes up in the morning and summons the rest of the world to his tasks. He cries, and someone comes to attend to him. When he is hungry, people feed him, and when he is wet, people change him. Very often, we do not completely outgrow that childish view that our wishes cause things to happen.

Hobbs was an orphan. He worked in a factory and every day he got a little money. Hard work made him thin and weak. He wanted to borrow a lot of money to learn to paint pictures, but he did not think he could pay off the debts.

One day a lawyer said to him, "One thousand dollars, and here is the money. "As Hobbs took the package of notes, he was very dumbfounded. He didn't know where the money came from and how to spend it. He said to himself, "I could go to find a hotel and live like a rich man for a few days; or I give up my work in the factory and do what I'd like to do: painting pictures. I could do that for a few weeks, but what would I do after that? I should have lost my place in the factory and have no money to live on. If it were a little less money, I would buy a new coat, or a radio, or give a dinner to my friends. If it were more, I could give up the work and pay for painting pictures. But it's too much for one and too little for the other."

"Here is the reading of your uncle's will," said the lawyer, "telling what is to be done with this money after his death. I must ask you to remember one point, Your uncle has said you must bring me a paper showing exactly what you did with his money, as soon as you have spent it. "

"Yes I see. I'll do that, "said the young man.
