First-year college students often are expected or required to live in dormitories. In the rest years, it’s usually up to those students to decide whether to live on or off campus.
But some schools don’t provide an option and require four years of on-campus living for full-time students. Living on campus has been shown to increase retention (保留) and attendance rates among freshman and second-year students, according to a 2021 report. There are exceptions, however. At some colleges, students may be freed from the requirement if they are, for instance, commuters (通勤生), fifth-year seniors, at least 23 years of age or legally married.
Residential housing at colleges is not limited to shared rooms and bathrooms. Alternatives include flats, apartments, Greek houses or living-learning communities for students with shared interests. On-campus students also have access to services and resources such as residence life staff who can help if a housing issue arises. When students live in a community, they are forced to live with different people, learn more about themselves and about the others, and tell each other their stories.
On the other hand, off-campus living provides students with more independence, as they are not constrained by school housing policies. Off-campus students gain more real-world experience in areas like paying their own bills, finding renter’s insurance, cooking their own meals and negotiating or reviewing contracts. If students are choosing to live off campus, they should really think it through and talk to someone that lived off campus. Do their homework and look at all the costs before they make that decision. Make sure, too, that they are choosing people that they can live with.
At first glance, off-campus housing can appear less expensive. But the additional expenses outside of rent — like utilities, groceries, Internet access, cable and furniture — are often overlooked. To reduce off-campus costs, some students choose to overpack houses or apartments, sometimes with four or five people in a two-bedroom house. Unlike off-campus housing, the total cost of living on campus is typically all-inclusive, coveting rent, utilities, furniture, Wi-Fi and a meal plan.

Health organizations such as the UK’s national health services recommend that adults take 10 micrograms, or 400 international units (IU) of vitamin D every day, while the National Institutes of Health advise that most adults take 600 IU, with both bodies cautioning against taking more than 4,000 IU per day. Having too much vitamin D can cause a build-up of calcium (钙) in the blood, leading to symptoms such as nausea and kidney stones.
But Patrick J. LaRiccia at the University of Pennsylvania and his colleagues recently found that a daily dose (一剂) of 5,000 IU may reduce the risk of influenza-like symptoms. They wondered whether this higher-than-recommended dosage may also have other positive effects.
So the team asked 196 adults to take 5,000 IU of vitamin D3 every day for about nine months. The adults, aged 47 on average, were aware of the dose they were having. The researchers also analyzed the data of more than 1,900 people who weren’t given the 5,000 IU daily dose of vitamin D. However, they were free to take vitamin D supplements if they wished. Towards the end of the study, across this group, the average reported dose was 1,318 IU and the average age was 50.
Over 10 months, those on the 5,000 IU dose had a lower risk of being hospitalized due to any cause, and they had to visit the emergency room or be admitted to intensive care less than people in the other group. No participants reported side effects.
However, LaRiccia says the team can’t rule out the age difference as a possible cause of these results, with those in the high-dose group potentially avoiding hospital because they were on average three years younger. The nationalities of people in the two groups also differed, with fewer Hispanic and Latino people in the high-dose group, which may have affected the results.
“The findings are promising, but the study was relatively small and the study period was too short to monitor any long-term safety issues of such a high daily dose of vitamin D,” says JoAnn Manson at Harvard University.

On March 1, Dr. Joseph Dituri began a project to stay for 100 days at a special hotel called Jules’s Undersea Lodge 30 feet under the ocean surface in a conservation area in Key Largo.
The farther you go below the ocean’s surface, the greater the pressure. Dr. Dituri wanted to learn how this pressure would affect the human body over time. He believes that high pressure could help people live longer and stay healthier as they get older. It could also help doctors treat different medical problems, including brain injuries.
While he was living underwater, Dr. Dituri stayed busy. He often exercised in the morning. He kept teaching his college classes virtually and had online chats with over 5, 500 students from 15 different countries. He also worked with ocean experts to figure out ways to preserve the ocean. He even had a number of visitors who dove down to spend a little time with him.
On June 9, Dr. Dituri returned to the surface with a new world record, beating the old record of 73 days. Many friends, family, and other supporters were there to greet him and celebrate his success. Doctors quickly checked him out to make sure he was okay.
Actually, Dr. Dituri went through several big changes. For one thing, he became 1. 3 centimeters shorter during his time in the higher undersea pressure. Sleeping much better, his health greatly improved in a couple of ways. Dr. Dituri and his team plan to study the information they collected during the project. In November, Dr. Dituri will speak at an important medical meeting in Scotland about the discoveries the scientists made during the project.
Dr. Dituri says his favorite part of the project was talking with young people. “Who knows?” he said. “Maybe one day, one of them will come. back and break the record we just set. My greatest hope is that I have inspired a new generation of explorers and researchers to push past all boundaries.

I have a passion for fishing and animal protection, which can date back to my childhood. When I was young, my father was a fish and wildlife officer, so he traveled all over the province in the spring and fall. He loved his job, especially the part where he protected nature from human.
He’d taught me to fish alone, in silence, lost in my own thoughts.
I still remembered that special day. Midweek, even in late August, no one was around. Police Outpost Lake is as far as you can go and still be in Canada. Songbirds, ducks, and Canada geese glided (滑翔) by on the breeze, touching down briefly on the water’s surface before flapping and quacking their way back up into the sky, passing in front of the sun, temporarily blocking its warming rays.
“How can I get the fish with these birds making noise?” I complained, rod (鱼竿) in my hand.
“Be patient, Jacob. Birds won’t disturb you.”
Out of the corner of my eyes, I suddenly caught a glimpse of a few great northern loons (潜鸟) stayed together not far from the shoreline. Dad once told me loon usually travel alone, but here were five of them in a group. Maybe it was a family? One loon, making odd sounds, swam away from the group, towards me.
This is unusual.
The loon rested in the shallow water near shore, not ten feet away from us. It was so close, we could see its red eyes.
“Look at that beak (喙)!”I said. “It could easily hurt us to death with that thing! It could tear our faces! Blind our eyes!”
Walking into the water, getting closer to the loon, we both saw thin wire wrapped around its neck. Fishing line maybe? Was there a hook(钩子)on the line, too? Was the loon asking us for help?

Four Tips to Stay Safe During a Heat Wave Very hot temperatures have been breaking records during the summer across USA. But it’s not just in the USA heat wave in June set new record highs. So what is a human to do?
During a heat wave, you have to dress properly. Clothing like loose and light-colored clothes are best if you have to work or be outside.
If possible, participate in outdoor activities during the morning hours.
Heat-related illness can affect anyone, but some people are particularly at risk. If you live with, or know people, like young kids, the sick or elderly, overweight people, outside workers, check on them frequently during a heat wave. We should monitor those at risk at least twice a day for signs of heat exhaustion or heat stroke, and babies and young children, even more frequently.
A.Avoid the Side Effects |
B.Protect Those Most at Risk |
C.Here are four heat wave safety tips to help you deal with the dangers. |
D.If not, you can put off them until evening when temperatures are cooler. |
E.During a heat wave, you’d better stay indoors where there’s air conditioning. |
F.This will help protect yourself from sunburn and help you keep a little cooler. |
G.That is the best way to keep you from being affected by the high temperatures. |
After traveling through space for seven months, China’s Tianwen 1 has reached Mars and successfully entered the planet’s orbit on Wednesday—bringing it one step closer to landing on the surface.
Tianwen 1, which got its name from an ancient Chinese poem, is made up of an orbiter (轨道飞行器), lander and a six-wheeled rover (巡视器) carrying scientific instruments, according to the China National Space Administration(CNSA).
The CNSA said the probe (航天探测器) is expected to land on the planet’s surface in May or June, and the rover is expected to stay for three months, with the hope that it can gather important information about Mars’ geological structure, atmosphere, environment and soil, and search for any signs of water.
Tianwen 1 was launched last July, and its arrival in the Mars’s orbit makes China the sixth country in history to reach Mars. So far, the United States and the former Soviet Union are the only two countries to land a spacecraft on the surface of Mars. But the European Space Agency and India have already sent spacecraft to enter the planet’s orbit—and on Tuesday, the UAE (阿拉伯联合酋长国) joined their ranks, with its Hope Probe successfully entering orbit.
With Tianwen 1, China is the first nation to attempt at sending both an orbiter and a rover on its first Mars mission on its own. According to the scientific team behind the mission, the probe will orbit, land and release a rover all on the very first try, and carry out experiments with an orbiter. By contrast, NASA sent many orbiters to Mars before ever attempting a landing, since pulling off the landing is a far more difficult task.
China’s first attempt to reach Mars was actually in 2011 with the Yinghuo 1 probe, which was supposed to orbit the red planet and study its environmental structure. It was launched (发射) from Kazakhstan together with the Russian Phobos-Grunt mission in November that year.

Everyone knows they feel amazingly good and refreshed (使精神振奋) after a good night’s sleep but now scientists have discovered it can help you to live longer too. According to a study in the US, healthy sleeping habits mean men can live almost five years longer, and women for two years. It also found that sleep is good for our health and reduces the risk of heart disease.
However, the study by the American College of Cardiology shows it’s not just about how long you sleep and the quality of your sleep is important too. Dr Frank Qian, who led the study, said sleep must be restful. The researchers said that sleep of high quality for adults was decided by five important factors: getting seven to eight hours of sleep each night; having trouble falling asleep no more than twice a week; having trouble staying asleep no more than twice a week; not using medicine to get to sleep; and waking up feeling rested at least five days a week.
Each factor was given one point, with a maximum (最大值) of five points for the highest quality of sleep. The researchers looked at the results of a survey of 172,321 people in the US that measured their health habits, including sleep, over five years. They found that people who had all five points were likely to live longer and lead healthier lives than those who had sleep difficulties.
According to the Sleep Charity, a good night’s sleep can improve people’s memory and immune (免疫的) system. Dr Qian admits that no one’s sleep is perfect—everyone has a late or restless night sometimes. However, he said, “Even from a young age, if people can develop these good habits of getting enough sleep, making sure they are sleeping without too many difficulties, which stem from daily troubles or noisy surroundings. And gradually it can greatly benefit their long-term health.”
The study was based only on people reporting their own sleep habits rather than recording them scientifically, so this may have affected the results and various study ways are needed.
