Articling and Summer Law Student Programs
Law students can apply to work for the Ontario government—as either a summer law student or an articling student. If you are experienced with Aboriginal communities or have an interest in Aboriginal law, you can also apply to work specifically in this field as part of the Aboriginal Summer law program.
Who is eligible: The Summer Law Student Program is open to first and second year students enrolled in a law school. To be eligible for the articling program, candidates must have either completed law school at the start of the articling period or have received a certificate of qualification from the National Committee of Accreditation.
The Tibet autonomous region has placed nearly half its land area under the strictest ecological supervision (监督).It was announced at an annual meeting of the regional People's Congress, which kicked off on Wednesday.
The ecological protection area, which covers more than 539,000 square kilometers, makes up 45 percent of the region's area, and 22 ecological reserves have been built and are operational.
According to the government work report, the rate of days with good air quality in Tibet's cities has reached 99.4 percent, and all the region's drinking water sources have met applicable standards.
The report also said that the number of Tibetan antelope (羚)in the region has risen to more than 200,000, wildlife species to 1,072 and black-necked cranes to more than 8,000. Five rare new species have been discovered in recent years. The region has spent 12.2 billion yuan ($1.9 billion) on ecological protection projects in recent years. Five cities and three counties have been named as national-level ecologically civilized model cities and counties, and more rural residents have benefited financially by undertaking part-time ecological protection work.
More advanced monitoring facilities have been in place in the reserve, with more ecological protection inspectors employed to undertake protection work. The professional ecological inspectors are provided with basic tools such as motorcycles, telescopes and paging receivers, and they provide feedback regularly. Professional inspectors also receive one week of training every year from professors at Tibet University.
Kunsang Darje, a railway maintenance worker in Nagchu, said that apart from maintaining the railway and highway, he also collects trash along the section with his colleagues. "The place I work is in a no-man's land, and I think it's very important to protect the animals there without affecting them with human activities, and we are also bound to take responsibility there," he said.
Many wildflowers of spring in eastern North America bloom thanks to ants. The tiny six-legged gardeners have partnered with those plants and about 11, 000 others to spread their seeds. The plants, in turn, "pay" for the service by attaching a calorie-loaded appendage (附属物) to each seed, much like fleshy fruits remunerate birds and mammals that desert seeds or poop (排泄) them out. But there's more to the ant-seed relationship than that exchange, researchers reported last week at the annual meeting of the Ecological Society of America, which was held online.
Many ants eat seeds. Certain plants attach a nutritive globe called an elaiosome(油质体) to their seed coats, which serves as a favorite lunch for the ants' young and gives ants a handle on seeds that can be bigger than their heads. Until now, researchers assumed the ants simply carry the seeds to their nests, feed the elaiosome to their young, and deposit the seed either outside or inside at the colony's "garbage dump", which provides a rich environment for shooting.
In both the field and the lab, Chelsea Miller presented ants with seeds from various trillium (延龄花) species and found the ants were quick to pick up some species' seeds while leaving others to rot, Miller said. To find out how ants make their choices, Miller and Susan Whitehead at the Virginia Polytechnic Institute and State University (Virginia Tech) used techniques to analyze the chemical makeup of elaiosomes. They found that ants pick seeds based on the specific combination and concentrations of acid and other compounds made by the plant, 20 of which are unique to trilliums. The ants' tastes may affect plant species' distributions, says Kirsten Prior, an ecologist at Binghamton University: "Widespread trillium species are preferred by seed-dispersing ants compared to rare trillium species."
Melissa Burt, an ecologist at Virginia Tech, hopes these studies bring ants new respect. "Many people who talk about ants only know them as insects that are taking over their kitchens, but many ants perform important functions in ecosystems," she says. "Seed dispersal is just one of those."
When you're on a fishing boat, you may see flocks of birds following in your track, hoping to catch a snack. Now scientists say they can use those birds' behavior to track illegal fishing boats.
Here's how it works: Researchers attached data recorders to the backs of 169 albatrosses (信天翁) in the Southern and Indian oceans. The devices weighed only an ounce and a half, but they included a GPS and were able to detect the presence and intensity of radar signals coming from boats. That information was then transmitted by satellite, so the researchers could track the location of the birds and thus the radar-emitting boats in real time.
The scientists then cross-checked that data against the known locations of boats, gathered from a system that boats use to declare themselves, called the Automatic Identification System (AIS). And differences appeared frequently.
More than a third of the times the birds' recorders detected radar signals, and therefore a boat, no such boat appeared in the official log (航海记录)—meaning that the vehicles had likely switched off their Automatic Identification Systems—something the researchers say probably happens in illegal fishing operations.
The work suggests birds could be an effective boat-monitoring tool—as long as illegal fishing operations don't target the birds. Fortunately, such a task would be difficult.
“Around fishing vessels, you can get hundreds of birds at any one time that are all flying around. So it's not really possible to target a specific bird. And the birds with recorders on are not marked in any way. So it's difficult for fishermen to pick out a specific bird," said study author Samantha Patrick, a marine biologist at the University of Liverpool.
Patrick's bigger concern is that albatrosses often get hooked on fishing lines. And though regulations have been established to protect against that happening—with success—illegal boats don't necessarily obey. So scientists might be underestimating the risk posed to albatross populations. But this system could mean that those illegal boats may have a tougher time flying under the radar.
Dogs, more so than almost any other domestic pets, are desperate for human eye contact. and according to a new study, that pull on the heartstrings might be exactly why dogs can give us those looks at all.
Studying the two animals is a bit like cracking open a four-legged time capsule. A paper published in the Proceedings of the National Academy of Sciences found that dogs' faces are structured for complex expression in a way that wolves' aren't.
For the study, a team looked at two muscles (the RAOL and LAOM muscles) that work together to widen and open a dog's eyes, causing them to appear bigger and more lovely, which we read as distinctly humanlike. The muscles for two short, straight lines, which connect the ring of muscle around a dog's eye to either end of the brow above. Therefore, they concluded that the origin of these complex facial expressions is after dogs splitting from wolves. Research has also shown that when dogs work these muscles, humans respond more positively. This isn't simply a coincidental love story, in which the eyes of two species just so happen to meet across a crowded planet.
For a species to change quickly, a pretty powerful force must be acting on it. .We connect more deeply with animals capable of making humanlike facial movements, so dogs have evolved to look like our own human babies to be selected for adoption.
A. Dogs are similar to wolves.
B. And that's where humans come in.
C. It's hard for most people to resist the shining eyes of a little dog.
D. But in the four gray wolves the researchers looked at, neither muscle was present.
E. Like the other best partnerships, this one is more likely the result of years of evolution.
F. Researchers have long been interested in the ways dogs make eye contact with humans.
G. Dogs split off from their wolf relatives — specifically, gray wolves — as many as 33, 000 years ago.
At the mid-May in 2018, the 69-year-old amputee(被截肢者) Xia Boyu finally stood proud on two artificial legs on the peak of Mount Qomolangma, a symbol showcasing to the world the power of 1.
More than 40 years ago, Xia 2 both of his feet to frostbite after lending his sleeping bag to a team member during the trip to climb Mount Qomolangma.
Even though artificial legs were not 3in China at the time, Xia strongly 4 that he would one day fulfill his 5 dream and so, before that day came, the best thing to do was to 6 himself by training constantly. Three years later he finally got his new legs, which enabled him to 7 his sports career.
However, fate once again took a 8 turn when he was in his 40s. In 1993, illness 9 on the stumps(残肢) on his legs, which required 10 third of his lower legs be amputated. Three years after that, he was diagnosed with lymph cancer.
Over the years, Xia never gave up his dream of climbing Mount Qomolangma. 11 to his final successful climb in 2018, he had tried four other times to climb to the summit, but each time Lady Luck gave him the 12 .
The last time he 13 his dream was in 2016. The then 67-year-old was only 94 meters from the summit, but a snow storm 14 his way. Taking his team members' 15 into consideration, Xia made the16 decision to go back.
On May 14, Xia felt 17 and a strong sense of fulfillment welled up in him, standing on the peak of the highest mountain in the world.
"The key is to focus on your dreams, instead of the 18 you encounter along the way. I didn't regret anything that I had done and accepted everything that life had 19 me, but I never stopped fighting against 20 ," Xia said, stressing that fulfilling one's dream has nothing to do with age, disability or the thoughts or expectations of others, but a firm belief in yourself.
It's not surprising that we feel blue during the winter months. There's even a recognized form winter depression — Seasonal Affective Disorder (SAD). Scientists think that many factors may result the problem.
Many of us know those have mild cognitive (认知的) problems seem to function less well during the winter. A study of 3,353 older adults confirmed this and (suggest) that winter might be the most likely season to get an Alzheimer's diagnosis. Not only that, other researches show that younger adults have a (bad) memory and attention in the colder months than the old. Doctors say getting enough sleep will improve memory and(concentrate).
What person with joint aches and pains doesn't complain about feeling more terrible during winter? Some doctors think it's linked to (change) in barometric (气压的)pressure. And, of course, when the weather is bad, we're less likely to exercise. But in fact staying active will help keep your joints supple (有弹性的) and (strength) your muscles. Just a few minutes every day will help. And it's important to maintain a healthy weight, as extra kilos put extra pressure on joints.
So if you feel down or moody in winter, try to get outdoors as much as possible (ensure) enough better sleep at night, make the most of the available daylight and take regular exercise. Only in these ways can we (success) get rid of winter depression.

Time fly like an arrow. I'm already in the second half of Senior Grade 3 before I realized it. It is only a little more than three months before I graduate middle school. At the present, I'm busy review my lessons in order to take the College Entrance Examination. I hope to go to Beijing University, that is one of the best university not only in China but also in the world. I'll try my best to turn your dream into reality. Most of my classmates are also studying very hardly to realize their dreams. I do believe everyone will be able to enter an university or college.
