1 . Most people agree that eating healthy food is important. But sometimes making good food choices can be difficult. Now there are apps that can help people learn about the food they eat to improve their health and their dining out experience.

Open Table app

Open Table app helps people choose restaurants when they want to go out to eat. It is a free service that shows users restaurant available based on where and when they want to dine. It gives users points when they make reservations, which can add up to discounts (折扣) on restaurant visits.

Max McCalman’s Cheese &Wine Pairing app

Wine and cheese can be a great combination. But which wines go best with which cheeses? Max McCalman’s Cheese & Wine Pairing app can help. It provides information about hundreds of different cheeses and suggests wines to pair with each. Max McCalman’s Cheese & Wine Pairing app is free.

Happy Cow app

Vegetarians do not eat animal meat. Vegans do not eat any animal products. The Happy Cow app is made for both groups. Users can search for vegetarian-vegan restaurants and stores around the world.

Local Eats app

Restaurant chains, like McDonalds, can be found almost anywhere a person might travel. But sometimes travelers want to eat like locals. The Local Eats app is designed for that. It can help you find local restaurants in major cities in the US and in other countries. It costs about a dollar.

Where Chefs Eat app

“Where Chefs Eat” is a 975-page book. Most people would not want to carry that around. But there is a much lighter app version of the same name for just $15. Six hundred chefs provide information on 3,000 restaurants around the world on the Where Chefs Eat app.

2 . After years of heated debate, gray wolves were reintroduced to Yellowstone National Park. Fourteen wolves were caught in Canada and transported to the park. By last year, the Yellowstone wolf population had grown to more than 170 wolves.

Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States, but they were gradually displaced by human development. By the 1920s, wolves had practically disappeared from the Yellowstone area. They went farther north into the deep forests of Canada, where there were fewer humans around.

The disappearance of the wolves had many unexpected results. Deer and elk populations — major food sources (来源) for the wolf — grew rapidly. These animals consumed large amounts of vegetation (植被), which reduced plant diversity in the park. In the absence of wolves, coyote populations also grew quickly. The coyotes killed a large percentage of the park’s red foxes, and completely drove away the park’s beavers.

As early as 1966, biologists asked the government to consider reintroducing wolves to Yellowstone Park. They hoped that wolves would be able to control the elk and coyote problems. Many farmers opposed the plan because they feared that wolves would kill their farm animals or pets.

The government spent nearly 30 years coming up with a plan to reintroduce the wolvers. The U.S. Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone. Today, the debate continues over how well the gray wolf is fitting in at Yellowstone. Elk, deer, and coyote populations are down, while beavers and red foxes have made a comeback. The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.

5 . History can be found at every turn, and every corner, as you walk the streets of this architectural marvel of a city, and at Powis Place and Fraser Studios you are just a short 15-minute walk away from one of the universities in the country. Links can be found to the University of Aberdeen as far back as 1495, beautiful medieval (中世纪的) campus to back up its claims.

It makes it the fifth oldest university in the whole of the UK, and as a result it has always been a regarded higher education establishment. It has been voted the 2019 Scottish University of the Year and ranked in the Top 30 Universities in the UK in 2019. It attracts people from all over the UK and abroad. With distance learning choices, it is an attractive proposition to many students. The Sir Duncan Rice Library has perfect views of the entire city and beaches, and the university has one of the largest medical campuses in the whole of Europe.

Aberdeen University Students’ Association (AUSA) is home to over 150 societies and hundred activities relating to those societies. It ensures that whatever you are interested in you are well served when moving to the city as a student. It is a fantastic way to meet and make new friends with people from all over the world. Within the Union there is a café and a shop, with many food outlets providing daily refreshments (茶点) during breaks between lectures and study. There are also plenty of volunteering and training opportunity to take part in, whether you are looking for a hobby, to help others, to present your CV, or all of the above.

The University of Aberdeen certainly holds some reputations, home to five previous Nobel Prize winners, an internationally-focused university in teaching and research, and even its very own tartan created in 1992 to celebrate the university’s 500th anniversary.

7 . The exhibit, Digital Dunhuang — Tales of Heaven and Earth, which was held at the Hong Kong Heritage Museum, brought to Hong Kong more than 100 exhibits including the visual murals and other related programs that could allow visitors to learn about the art and history of the Mogao Caves in a fun way.

“Dunhuang was an international city, a place where East met West, on the old Silk Road. So the Mogao Caves, which were completed in a period of over 1,000 years, record the ways of life and beliefs of the different peoples that crossed paths there,” explained Fion Lin of Hong Kong Heritage Museum.

Visitors can now get up close and personal with these faraway treasures without having to step into the caves, thanks to the digitization project of the Dunhuang Academy, a pioneer that has made great progress in the digitization and 3D scanning of the Dunhuang treasures.

“Studies have shown that in a cave, both temperature and CO₂ concentration level can rise with 15 tourists inside for ten minutes. As a result, the wall paintings are going to eventually fade. Digital technology has helped to strike a balance between sharing the treasures and protecting them,” said Lin.

However, digitization of the caves faces many challenges such as poor lighting and rough wall surfaces. On average, 40,000 pictures have to be taken to cover 300 m². Great amount of efforts have been made to piece the pictures together. What the exhibition presented is the result of years of hard work.

During the exhibition period, a mini display on Dunhuang music culture was also being held at the Museum for public participation.

9 . The most famous war movies reflect the American public’s continuous fascination with World War Ⅱ and the Vietnam War. Many movies of this kind have been well­received when they were first shown, but few of them have enjoyed lasting fame and popularity. The films on the list of the five most famous war movies still remain fresh and are popular among many people.

The Longest Day

An all­star cast recreates D­Day and the Normandy attack, the greatest landing and aerial (空中的) invasion in history. This is probably the most famous war movie because of the large number of big stars who have roles in the film.

Apocalypse Now

The Dirty Dozen

Lee Marvin, playing an officer who thinks and acts independently, is appointed to train twelve prisoners, most of whom have been sentenced to death, to go on a suicide mission to kill several Nazi generals. If any of the men makes it back, they may get a pardon. This is one of the most popular war movies ever made.

Platoon

This famous war movie is the fictional account of a platoon (排) in Vietnam that is divided into two competing groups. The plot is partly based on the director Oliver Stone’s real life experiences.

Midway

10 . Teenagers’ fitness is now a major concern，and physical exercise is very important. It reduces stress and improves fitness. Exercise makes your body strong，and helps you to keep the right body weight. Sports scientist Dr. Helen Lopez offers the following advice to teenagers：“First，you need to find out your present level of fitness. Then you can design a programme that will help you become healthier.”

Dr. Lopez suggests that there are three levels of fitness that need a change of lifestyle.“Overweight”means that the person gets very little exercise and often has a serious weight problem. “Inactive” means that the person does not join in many physical activities，but is not seriously overweight.“Active”refers to people who take part in sports and other physical activities，but do not have a high fitness level.

According to Dr. Lopez，overweight teenagers should work out to keep healthy.“Ride a bike，play volleyball or basketball for a while，and go for a twenty­minute walk each day. All these will help to burn calories.”Inactive teenagers should do similar activities, but add some bending and stretching exercises, such as push­ups and sit­ups, starting with twenty of each a day.“Inactive people can take a little more exercise than overweight people because their bodies are stronger，”Dr. Lopez said. The same rule applies to active teenagers.

Dr. Lopez suggests one hour a week or more on running and other forms of intensive exercise，together with fifteen minutes a day spent on stretching and bending activities.“These are really important in order to prevent injuries,” Dr. Lopez said. Some weight­training and other body­strengthening exercises could also be planned in the programme in order to increase the person’s strength.
