How could you be "just ahousewife" when the basic social unit of society depends on you and yourservice? A housewife works for the longest hour, supporting your husband, childstudies, caring for eld-ers, managing finances, paying bills, grocery shopping,cooking according to individual taste, cleaning, etc. A housewife could beanyone: daughter, wife, mother, teacher, financial advisor, fashion designerand nurse, gardener, driver, cook, and so on. Don't think you are not being paid for it.  You get the re-ward that no money canoffer-the love and affection of your family, their trust in you, ahappy home and your own satisfaction.

    It is you who choose to be in thisoccupation, willingly or for any other reason. After a busy day, all wait to return to the comfortable home set by you.They know you will be there to absorb all their stress and tiredness and relaxthem. Would the life have been the same had you been working outside to earnsome money? Would you along with your family have been able to buy all thecontent in life that you are enjoying now with that money?

    Respect yourself for what you are. Introduce yourself to the world with the same dignity. The world understandsthe importance of your job; it's time to make them accept it. Introduceyourself with pride and with twinkle in your eyes "I am a housewife".Kick that "just" out.

    Driving in Canada is similar to driving in many parts of the United States. Distances and speeds, however, are posted in kilometers per hour and some signs, particularly in Quebec, may only be in French.

    Unless otherwise posted, the maximum (最大限度的) speed limit in Canada is 50km/hr in cities and 80km/hr on highways. On rural highways, the posted speed limit may be 100km/hr. It is illegal to take automobile radar detectors (汽车雷达检测器) into Quebec, Ontario, Manitoba, and the Yukon. Seat belt use is required by law for all passengers, and child car seats must be used by children under 40 pounds. Some provinces require drivers to keep their vehicles' headlights on during the day and some have banned (禁止) driving while using a hand-held cell phone. Motorcycles cannot share a lane (车道), and safety helmets for motorcycle riders and passengers are necessary. Running a red light is a serious crime throughout Canada and drivers are advised to stop before starting when a light turns green.

    Winter travel can be dangerous due to heavy snowfalls and icy conditions. Some roads and bridges are often closed in winter. Snow tires are required in some provinces. Travelers should also be careful about animals while driving at night in rural areas.

    Highway 401, from Detroit to Montreal, is one of the busiest highways in North America. It has been the scene of many deadly traffic accidents due to sudden and severe weather changes, high rates of speed, and heavy truck traffic. Thus drivers should be alert while travelling here.

    Please refer to our Road Safety page for more information. Also, we suggest that you visit the website of Canada's national authority responsible for road safety.

    Fikiri Kiponda's path from accountant to marine (海洋的) conservationist was sparked by a chance encounter.    After securing his dream job, Kiponda decided he wanted more. He wasn't quite sure what he was looking for until he ran across some turtle hatchlings.

    He didn't know it was turtle. Fortunately enough he got the right person to ask and he got motivated. That person was Nkindi, a staff member at the Watamu Conservation project who later invited him to volunteer on the project. He later left his accounting job and fully devoted himself into the world of sea turtles. Now，he runs and spends his time nursing critically endangered sea turtles back to health.

    Sea turtles have been around for nearly 110 million years and are now considered highly endangered. Their preservation rests on activities of conservationists such as Kiponda as these turtles face numerous threats and signs of their extinction in the next 50 years.

    Local fishermen traditionally catch them to supplement their own low catch rates and sell them for their oil. As changes are made to accommodate more hotels for tourists, there is less available beach land for turtle nesting.

    Kiponda's passion has now spread to his community, changing their attitude towards sea life preservation with his “by-catch release programme.”

    Through this program, fishermen are now paid for returning turtles accidentally caught in their fishing nets. The healthy ones are tagged and released into the marine park while he takes care of sick and injured turtles back to health.

    Before the launch of pioneering spirit like this, turtles caught by fishermen were used for their meat and their oil extracted (提炼) for its medicinal properties.

    “Releasing the turtle back into the ocean is a very good feeling, like, you feel like you've done something concrete and I guess everybody would love to do that...so I guess it's unique work.”

    A young woman carrying a three-year-old child got on a bus. The conductor hurried to give her a warm welcome and then kindly asked the other passengers to make more room for the woman and her child. On seeing this, people were surprised and began to talk. "You know this conductor used to be very rude. Now suddenly he has changed his bad behavior, "said a middle-aged man.

    "Yes, he should be praised and we must write a letter to the company," said a second passenger. "That's right," another lady said, "I wish a newspaper reporter were here so that more people could learn from this conductor.”

    Just then a gentleman who looked like a teacher turned to the conductor and said, "Excuse me, but can I know your name, please? Your excellent service must be praised..."

    Before he could open his mouth, the three-year-old child sitting on the young woman's lap interrupted, "I know his name. I call him Dad."

    Have you ever pressed the pedestrian button at a crosswalk and wondered if it really worked? They're called “placebo(安慰剂）buttons” 一buttons that mechanically sound and can be pushed，but provide no functionality.

In New York City, only about 100 of the 1, 000 crosswalk buttons actually function. Crosswalk signals were generally installed before traffic jam had reached today's levels.

    But while their function was taken over by more advanced systems—such as automated lights or traffic sensors — the physical buttons were often kept, rather than being replaced at further expense. Other cities，such as Boston， Dallas and Seattle， have gone through a similar process, leaving them with their own placebo pedestrian buttons. In London, which has 6, 000 traffic signals， pressing the pedestrian button results in a reliable “Wait” light. But that doesn't necessarily mean that the “green man”— or “pedestrian stage” in traffic signal design profession — will appear any sooner.

    “We do have some crossings where the green light comes on automatically, but we still ask people to press the button because that enables accessible features,'' said Glynn Barton, director of network management at Transport for London.

    These features, such as blind tracks and hearable traffic signals, help people with visual disorder cross the road and only function when the button is pressed. As for the lights, a growing number of them are now combined and become a part of an electronic system that detects traffic and adjusts time frequency accordingly (giving priority to buses if they're running late, for example), which means that pressing the button has no effect.

    According to Langer, a Harvard psychologist, placebo buttons give us the illusion (错觉)of control — and something to do in situations where the alternative would be doing nothing. In the case of pedestrian crossings, they may even make us safer by forcing us to pay attention to our surroundings. “They serve a psychological purpose at the very least,” she added.

Plants, and the insects which rely on them, are the living foundations of our planet. But these foundations are under stress because we have a tendency to replace fields and forests with decorative trees and shrubs imported from around the world. Adding to the problem, our obsession (痴迷) with perfection leads us to use a lot of pesticides (杀虫剂).

These actions are part of the reason global biodiversity is crashing. There are over three billion fewer wild birds in North America than there were in 1970. Recent research shows that insect numbers, even in nature reserves, have fallen, and 40 percent of all insect species may be extinct within a few decades. This is discouraging news; however, there are actions we can take to help bring at least some species back.

The first step is to redefine our concept of "garden" to include more than just plants. We need to intentionally share our space, and not just with the birds, bees and butterflies that visit our flowers, but also with the little insects that may eat a part (very rarely all) of our plants. Therefore, we must limit pesticide use. It's crucial to support nature's recovery, and it's much better for everyone: no doctor has ever recommended long-term exposure to pesticides.

Many drought-tolerant plants brought in from across the planet are being passed off as ecofriendly. However, mostly they're not. Yes, you're saving water, but these foreign plants can become disasters when they escape our yards. Helping the environment can be about more than saving water. Even in drier areas, like the American West, the selection of attractive native plants to choose from is vast. If dry is your style, there are native wildflowers, flowering bushes and trees that allow you to save water and nature.

Xeriscapes (节水型园艺) leave many gardeners thirsting for green, and there's an important alternative that has been largely ignored. For those disenchanted with dry landscaping, using underappreciated and water-loving native plants to make your garden a real-life oasis (绿洲) could be lifesaving to wildlife. In nature, this unsung group of native plants is limited to riparian zones, the narrow belts of green along water bodies, but if consumers demand them, nurseries will increasingly carry these riparian species, and the presence of such plants in the garden will provide for many animals including not just butterflies and their relatives but also colorful birds.

The ideal garden would offer a combination of drought-tolerant native plants and a few species that need a little more water, providing options for little guests and the bigger ones that will come to eat them. As more creatures stop by to share our yards, we will be making nature, and us all, a little healthier.
