Have you felt annoyed when a cell phone rings during the class? Something must be done to stop this. Now in New York City, USA, a rule is carried out in schools. Students can't even bring cell phones to school. Is it a good thing or not?

    Anxious parents say that cell phones are an important tool in holding New York City's families together.

    "I worry about it." said Elizabeth Lorris Ritter, a mother of a middle school kid. "It's necessary in our everyday life. We have a washing machine. We have running water, and we have cell phones."

    Many American parents think cell phones connect them to their children on buses, getting out from subways, walking through unknown places.

    "I have her call me when she gets out of school," said Lindsay Walt, a schoolgirl's mother. "No one in New York is going to let their child go to school without a cell phone."

    What about the cell phone owners, the students? Most of the students said cell phones were essential and the cell phone was like an extra hand or foot for them.

    "I feel so empty," said May Chom, 14. There is also no way to listen to music on the way to school without my phone. It will be a really, really boring trip."

    Most of us have been in this situation: You're on your way to your friend's house, then you suddenly ask yourself,"Did I remember to turn the lights off?” For those with "smart homes", however, this wouldn't be a problem.

Over the last few years,smart home technology has become more popular. Thanks to user-friendly products like intelligent lighting and heating controllers, people can control nearly every electrical item in their homes from anywhere in the world.

    While smart homes aren't new, companies like Philips, Amazon and Xiaomi have finally brought automation to everyday people with affordable products like artificial intelligence(AI) speakers and sensors.

    “The obvious message is that you can stop wasting energy,” Tom Kerber, director of research for U. S -based digital company Parks Associates, told The Guardian.

    And the technology also has more meaningful uses. In Norway, for example, one company is using smart tech to make life easier for its elderly customers. Abilia's system allows carers to check up on patients through a tablet on a wall inside their home. The device sends patients reminders about tasks, such as when they need to take medication(冥想). It can even tell carers if there's any unusual activity in the home that could be life-threatening.

    “This kind of system allows people to take care of themselves, which is the most important thing,” Abilia's vice president, Oystein Johnsen, told the BBC. "It also saves the government money. In Norway, it costs 1 million kroner(about 0. 8 million yuan )per year to have someone in a care home. This system costs 15,000 kroner a year.”

    So, for those who have already "gone smart", will it ever be possible to go back to do things in the old-fashioned way? "I think it would be difficult. When we go to a friend's house or on vacation we find ourselves expecting the house to do things for us that we should do, "Poulson, 35, a senior program manager from Seattle.,U. S.,explained.

    China's college graduates are leaving first-tier cities（一线城市）for second-tier ones, according to the annual College Graduates' Employment Report issued on Monday.

    The report said that 22.3 percent of college graduates last year chose to work in first-tier cities—Beijing, Shanghai, Guangzhou and Shenzhen—down 1.3 percentage points from 2016 and 5.9 percentage points from 2013. In 2017, 21.7 percent of college graduates chose to leave first-tier cities after working there for three years, up 2.5 percentage points from 2016 and 8 percentage points from 2015.

    The report also found that leading second-tier cities are attracting more recent graduates. Around 35.6 percent of college graduates who chose to work in the top 10 second-tier cities such as Hangzhou, Chengdu and Wuhan, were from other regions in 2017, up 3.6 percentage points from the previous year.

    The report was based on a survey of 306,000 graduates from 30 provinces and regions. It was released by MyCOS, an education consulting and research institute in Beijing.

    Wang Boqing, founder of MyCOS, said large populations, traffic jam, smog, increasing property prices and great difficulty in obtaining permanent residence（居住）, or hukou in Chinese, have brought high pressure to life in first-tier cities for college graduates, which gives second-tier cities an opportunity to attract talented workers.

    Second-tier cities have rolled out a series of policies to attract university graduates, which include favorable treatment to obtain hukou, as well as housing and government subsidies（津贴）, he said. Wuhan, Hubei Province, has planned to build affordable housing for university graduates, and allow graduates to buy or rent apartments at a discount of at least 20 percent of the market price.

    Chu Zhaohui, a senior researcher at the National Institute of Education Sciences, however, said that the governments of such cities should notice that welfare（福利）, housing and money can attract people in a short time. “Professionals aim mainly at prospects（前景）for career development rather than just benefits,” Chu said, adding that those cities should maintain their advantages, such as low cost of living and nicer environments, to keep their appeal. The cities should provide more opportunities for employment that are similar to those in first-tier cities, he said.

    With its snow-covered mountains and a variety of wildlife, Yellow Stone National Park is one of the scenic treasures of the United States. Located primarily in Wyoming, the park hosts millions of visitors every year. If you plan to travel within the park, keep in mind advice from the National Park Service.

    Seasonal Travel

    Travel varies vastly from season to season. Roads are generally open in the summer except for cases of rock or mud slides, wild fires, accidents or road construction. Early snows in the fall can cause some roads to close temporarily. In the winter almost all roads are closed to motor vehicles, but snowmobiles and other snow vehicles with tracks are allowed. Roads begin to open for the spring by the latter part of April but can close if snowfall continues.

    Driving Time

    Grand Loop is the main road through Yellowstone National Park; it passes by most of the major attractions. These include Old Faithful, Yellowstone Lake and the Grand Canyon of Yellowstone. The maximum speed limit on the Grand Loop is 45 miles per hour, but the speed limit drops during some of the winding and twisting sections of this narrow road. Allow yourself at least two days to fully travel the loop due to the size of the park and being sometimes stuck in heavy traffic.

    Safety Awareness

    Buffalo(水牛)often block the roads in the park as they move through the fields. If a group is traveling across the road you are on  you can either wait for them to pass or find an alternative route. If you get out of your vehicle, the National Park Service says to stay at least 25 yards from any buffalo (and 100 yards or more away from bears and wolves). Buffalo are particularly unpredictable and charge people at speeds up to 30 mph.

    You can take your bicycle on any public roads and routes designed for bikes, but bicycles are not allowed on the park roads which are narrow with few shoulders. Altitudes range from 5, 300 to 8, 860 feet. The National Park Service recommends cyclists wear helmets and noticeable clothing.

    Lebanese filmmaker Nadine Labaki has become the first female artist in the Arab world to be nominated (提名)for an Academy Award ,or Oscar.

    Labaki directed the film Capernaum ,a film about a Syrian refugee (难民)boy and a Kenyan baby who live without parents on the streets of Beirut. It was nominated for best foreign language film.

Labaki will be one of the few female directors to compete for an Oscar this year. She told the Associated press "I wish there were a lot more women filmmakers this year represented, nominated in the Oscars. But I am sure in a few years we won't be having this problem anymore."

    Unlike in the West, women filmmakers are industry leaders in Lebanon.

Capernaum received a 15-minute standing ovation (热烈欢迎)at this year's Cannes Film Festival. It won the Jury Prize—the third-highest award given at Cannes.

    The United Nations has publicly praised the film. Lebanon's Foreign Minister said.

    Capernaum put a Lebanese touch on the international film industry.

    The Oscar nomination of Capernaum is the second for Lebanon in two years in the film group. It demonstrates the country's rising star power.

    Labaki called making the movie a life-changing experience. She said Capernaum helps humanize the real struggles of refugees only briefly talked about in the news.

    We can't help but acknowledge that there is a fear of refugees in general around the world and there are these walls we are building, and this fear that keeps growing," Labaki said.

    Capernaum will compete against four other films for the Oscar, including awards season favorite Roma. Directed by Mexico's Alfonso Cuaron, it earned 10 Oscar nominations, including for best picture.
