Welcome to our school. You can do a lot of things here. Come and join us.

    There are an extremely large number of ants worldwide. Each individual (个体的) ant hardly weigh anything, but put together they weigh roughly the same as all of mankind. They also live nearly everywhere, except on frozen mountain tops and around the poles. For animals their size, ants have been astonishingly successful, largely due to their wonderful social behavior.

    In colonies (群体) that range in size from a few hundred to tens of millions, they organize their lives with a clear division of labor. Even more amazing is how they achieve this level of organization. Where we use sound and sight to communicate, ants depend primarily on pheromone (外激素), chemicals sent out by individuals and smelled or tasted by fellow members of their colony. When an ant finds food, it produces a pheromone that will lead others straight to where the food is. When an individual ant comes under attack or is dying, it sends out an alarm pheromone to warn the colony to prepare for a conflict as a defense unit.

    In fact, when it comes to the art of war, ants have no equal. They are completely fearless and will readily take on a creature much larger than themselves, attacking in large groups and overcoming their target. Such is their devotion to the common good of the colony that not only soldier ants but also worker ants will sacrifice their lives to help defeat an enemy.

    Behaving in this selfless and devoted manner, these little creatures have survived on Earth, for more than 140 million years, far longer than dinosaurs. Because they think as one, they have a collective (集体的) intelligence greater than you would expect from its individual parts.

    It was a winter morning, just a couple of weeks before Christmas 2005. While most people were warming up their cars, Trevor, my husband, had to get up early to ride his bike four kilometers away from home to work. On arrival, he parked his bike outside the back door as he usually does. After putting in 10 hours of labor, he returned to find his bike gone.

    The bike, a black Kona 18 speed, was our only transport. Trevor used it to get to work, putting in 60-hour weeks to support his young family. And the bike was also used to get groceries（食品杂货）, saving us from having to walk long distances from where we live.

    I was so sad that someone would steal our bike that I wrote to the newspaper and told them our story. Shortly after that, several people in our area offered to help. One wonderful stranger even bought a bike, then called my husband to pick it up. Once again my husband had a way to get to and from his job. It really is an honor that a complete stranger would go out of their way for someone they have never met before.

    People say that a smile can be passed from one person to another, but acts of kindness from strangers are even more so. This experience has had a spreading effect in our lives because it strengthened our faith in humanity（人性）as a whole. And it has influenced（影响）us to be more mindful of ways we, too, can share with others. No matter how big or how small, an act of kindness shows that someone cares. And the results can be everlasting.

    Children who spend more time reading with their parents have a greater chance of becoming better readers than those who don't. With the help from their parents, children can learn techniques to improve their reading skills.

    "A lot of parents think after their child learns to read, they should stop reading to them," Donna George said. "They are sadly mistaken."

    George offers her services to parents at the Title I Learning Centers. She said reading aloud to children may be the most valuable thing parents can do. "It is better for children to hear things at a higher level than where they are," George said. "Parents are their child's first teacher." Parents help their children build listening, phonics, comprehension and vocabulary skills when they read aloud to them.

    Before parents can identify reading problems, they should escape the enemy —television and limit the time their children spend watching television. George suggested not allowing kids to have a TV in their bedrooms, setting a schedule of when kids can watch or keeping a list of how many programs children watch. Louise Joines said while her 14-year-old daughter and 10-year-old son enjoy reading, the television sometimes becomes a distraction. So she tries to build the situation by suggesting books the entire family will enjoy reading together, like the Harry Potter series.

    Parents who do not read themselves should not count on their children being interested in it. If parents would read to their children at least 15 minutes every day, children would not have so many problems in school. It is the parents' job to help build that desire in their children, and of course to know what kind of books to read is also important.

    Being a parent is tough. Prejudice against parents in the workplace only makes it harder.

    Asking for flexible schedule is not unique to working parents only. I've worked with people in their twenties that requested to work a four-day schedule so they could go back to school part time. I've seen older adults in the workplace change their schedules so that they can spend more time at home. Almost everyone has to cut out of the office every now and again for a doctor's appointment or other personal matters. Flexible schedules seem to be synonymous(代名词) with working parents, but in reality, they are not.

    Parents aren't devoted to their jobs. This is really surprising because it's quite the contrary. There is actually strong evidence that parents are more devoted to their jobs than many other employees. They are some of the most focused employees out there. Parents are less likely to change jobs than other employees. Stability(稳定) is key when raising a family.

    Parents aren't good team members. Since it is parents that need to leave the office at 5 or aren't able to come in before 9, most people think that the singletons on the team need to make up for it. In today's technology world, this is hardly the case. While many parents do limit their physical "in office" hours, most spend time on weekends, early mornings, and after work working. Besides, parents may be more likely to take vacations during major holidays due to children's school schedules.

    Parents are at work only out of financial needs. Why would anyone want to leave their children behind and come to the workplace if they didn't have to? Actually, a lot of people do. Caring for children is a wonderful experience, but everyone needs a break. Many parents may still be interested in their field of work, finding work interesting. Money is nice, but it's certainly not the only reason that parents are there.

    Going to university is supposed to be a mind-broadening experience.

    That assumption is possibly made in contrast to training for work straight after school. But is it actually true? Jessika Golle of the University of Tubingen, Germany, thought she would try to find out.

    Her result, however, is not quite what might be expected. It shows that those who have been to university do indeed seem to leave with broader and more inquiring minds than those who have spent their immediate post-school years in vocational training for work. However, it is not the case that university broadens minds. Rather, work seems to narrow them.

    After studying the early career of 2095 German youngsters, Dr. Golle reached the conclusion.

    During the period under investigation, Germany had three tracks in its schools: a low one for pupils who would most probably leave school early and enter vocational training; a high one for those almost certain to enter university; and an intermediate one, from which there was a choice between the academic and vocational routes.

    The team used two standardized tests to assess their volunteers. One was of personality traits and the other of attitudes. They administered both tests twice once towards the end of each volunteer's time at school, and then again six years later.

    Of the original group, 382 were on the intermediate track, and it was on these that the researchers focused. Of them, 212 went to university and the remaining 170 chosen for vocational training and a job.

    When it came to the second round of tests, Dr Golle found that the personalities of those who had gone to university had not apparently changed. Those who had undergone vocational training and then got jobs were not that much changed in personality, either except in one crucial respect they had become more responsible.

    That sounds like a good thing, compared with the common public image of undergraduates as a bunch of pampered layabouts(娇生惯养的闲人). But changes in attitude the researchers recorded were more worrying. In the university group, again, none were detectable. But those who had chosen the vocational route showed marked drops in interest in tasks that are investigative and enterprising in nature.

    And that might restrict their choice of careers. Some investigative and enterprising jobs, such as scientific research, are, indeed off limits to the degreeless.

    But many, particularly in Germany, with its tradition of vocational training, are not. The researchers mention, for example, computer programmers, finance-sector workers and entrepreneurs as careers requiring these attributes.

    If Dr Golle is correct, and changes in attitude brought about by the very training Germany prides itself on are narrowing people's choices, that is indeed a matter of concern.
