I was born on the 17th of November 1828, in the village of Nam Ping, which is about four miles southwest of the Portuguese Colony (殖民地) of Macao, and is located on Pedro Island lying west of Macao, from which it is separated by a channel of half a mile wide.

    As early as 1834, an English lady, Mrs. Gutzlaff, wife of a missionary to China, came to Macao. Supported by the Ladies' Association in London for the promotion of female education in India and the East, she immediately took up the work of starting a girls' school for Chinese girls, which was soon followed by the opening of a boys' school.

    Mrs. Gutzlaff's comprador(买办) happened to come from my village and was actually my father's friend and neighbor. It was through him that my parents heard about Mrs. Gutzlaff's school and it was doubtlessly through his influence and means that my father got me admitted into the school. It has always been a mystery to me why my parents should put me into a foreign school, instead of a traditional Confucian school, where my big brother was placed. Most certainly such a step would have been more suitable for Chinese public opinion, taste, and the wants of the country, than to allow me to attend an English school. Moreover, a Chinese belief is the only avenue in China that leads to political promotion, influence, power and wealth. I can only guess that as foreign communication with China was just beginning to grow, my parents hoped that it might be worthwhile to put one of their sons to learning English. In this way he might become an interpreter and have a more advantageous position to enter the business and diplomatic world. I am wondering if that influenced my parents to put me into Mrs. Gutzlaff's School. As to what other sequences it has eventually brought about in my later life, they were entirely left in the hands of God.

    Finding a winter job is often a proof that you're growing up, and it's also a method for earning money to pay for what you dream of. It's never too early to start considering the future. Now, here are some good choices for you!

Retail (零售) Sales

    Retail offers plenty of opportunities for teens that are looking for a job. This type of work can pay from $10 to $15 an hour depending upon the duty you are expected to take on. It can also be great for teens who are friendly and enjoy talking to other people. For more information, call us at 4005075.

Food Service

    A job in the food service industry is a natural fit for sociable teens who enjoy communicating with the public. It allows employees to work as part of a team while learning about following instructions. It also comes with the opportunity to earn between $8 and $10 per hour. Just dial 4005077 for more information.

Babysitting

    This job requires someone who is highly responsible. Though it pays generally between $6 and $8 hourly, it also requires a lot of patience. This is a great choice for teens who wish to make a career in teaching, child care, social work or any other field that makes use of social skills or requires interaction with kids. Got a question? Just dial 4005076.

Housekeeping

    This type of work can bring in about $5 an hour and it will allow teens to learn the tourism industry, so hotels are often looking for more housekeeping staff, and parks often need more people to assist with keeping public areas clean and organized as well. Telephone: 4005079

    Inspired by a 9-year-old cyclist, Lauren Turner, who can only use one hand, a group of University of Guelph students has won an international award for their invention — a bike brake lever (刹车手柄) that pulls both the front brake and the back brake at the same time.

    Lauren Tuner was able to ride her bike, but not as confidently and quickly as her friends.

    "She couldn't use the front brake. She only used the back brake, but the front brake makes you stop twice as fast," says Micha Wallace, who, with Katie Bell, Anina Sakaguchi and Andrew Morries won second prize in the James Dyson Award for their single-handed bike brake lever.

    "Lauren Turner tried the device (装置) first and she used it all last summer. She had no problems. It helped her go faster because she felt more confident in her braking abilities. She felt safer." says Wallace.

    The invention was the fourth-year design project for the four students. They designed, tested and created a prototype (模型) within a four-month period.

    When Wallace heard about the James Dyson Award on the news, she and her co-inventors entered their project in the U. K. -based contest, which rewards students designers who create products that improve the way we live. The students collected the runner-up prize — £2,000 for them and £500 for their school.

    As well, they had a chance to meet James Dyson, a U.K. famous inventor. Praising the students for their invention, Dyson says the single-handed brake lever could improve safety for all cyclists. By using both brakes at once, you could prevent the possibility of flying over the handlebars and ending up with an injury.

    The students hope to sell it to a major company. It may be used in other devices that require two hands for operation.

    Let children learn to judge their own work. A child learning to talk does not learn by being corrected all the time; if corrected too much, he will stop talking. He notices a thousand times a day the difference between the language he uses and the language those around him use. Bit by bit, he makes the necessary changes to make his language like other people's. In the same way, children learn to do all the other things without being taught to walk, run, climb, whistle, ride a bicycle…They compare their own performances with those of more skilled people, and slowly make the needed changes. But in school we never give a child a chance to find out his mistakes and correct them for himself. We do it all for him. We act as if we thought that he would never notice a mistake. If it is a matter in mathematics or science, give him the answer book. Let him correct his own papers. Why should we teachers waste time in such routine(日常的) work? Our job should be to help the child when he tells us that he can't find the way to get the right answer. Let the children learn what all educated persons must some day learn, how to measure their own understanding, how to know what he does not know.

Robots have long been drawing inspiration from animals, with the creation of robot dogs or snake-shaped robots. And yet, the field of robotics is far less enthusiastic about the other kind of living things—plants. Barbara Mazzolai, an Italian roboticist owes this to a misconception about plant behavior: that they cannot move or think. "It's not true at all, " she says. To challenge this view, Dr Mazzolai and her team recently launched a machine called "FiloBot", a robot based on a climbing species. 

To survive, a climbing plant must switch between several different behaviors. In forest environments, it must first grow out of the soil and travel along the ground in search of a support to hold onto, such as a nearby tree. Once a support is located, though, the plant fixes itself around the object and then growing towards the light. To choose the best angle to grow upwards, a climbing plant uses its shoots(芽) to receive information about light and gravity. 

FiloBot has sensors on its main shoot. It can 3D-print its body with plastic and grow at a controllable rate. These functions, researchers found, enabled FiloBot to cross gaps, and find things to attach to. The lack of heavy on-board computing device means that it is light and requires minimal care, while its slow pace means that it doesn't disturb things around it, making it possible to move through a complex, unseen environment, or monitoring disaster sites. 

For now, FiloBot is still being tested. Its tendrils(卷须) have not left the laboratory. Still, it has already been employed in deconstructing plant behaviour. For example, it was long assumed that climbing plants find their supports by growing towards shade, though the exact mechanism was unclear. FiloBot could imitate this behaviour by detecting far-red light, which is typical of shaded areas, providing clues to how plants do it. 

Dr Mazzolai hopes that such projects will inspire other roboticists to take their cues from plants and develop completely new technologies.
