Humans use electricity to light up the night sky. But did you know that nature itself can glow, too?

    {#blank#}1{#/blank#}. Some use their lights to communicate. Others shine to hunt, to mate or to protect themselves. The vampire squid, for example, gives out a cloud of light to scare enemies.

    In 2013, the US company Gleaux said it had created the world's first light-producing plant, reported the Daily Mail.

    {#blank#}3{#/blank#}.

    “People have dreamed about this stuff for many years,” said Alexander Krichevsky, the company's founder.

    He and other researchers are working toward a future in which glowing plants replace lamps and glowing trees line highways.{#blank#}4{#/blank#}, making them glow to let farmers know when they need water or are ready to be picked.

    While GleauX is working on glowing plants, the French company Glowee is trying to use glowing bacteria to light up shop windows and street signs. It is the same type of bacteria that causes certain sea animals to light up.

    {#blank#}5{#/blank#}.The company is now working on a light that shines brighter, lasts longer and comes in different colors.

    “Our goal is to change the way we produce and use light,” said Glowee founder Sandra Rey. “We want to offer a global solution that will reduce the 19 percent of electricity consumption used to produce light.”

A. People are also creating glowing bacterial art that you can hang in your home

B. Scientists have found many glowing creatures, most of which live in the ocean

C. Krichevsky also hopes the technology could be used in crops

D. Researchers around the world are looking into nature's lights for new ideas

E. It is a genetically-modified plant that glows like fireflies do

F. In 2016, Glowee created a bacteria-powered light that glows for three days

G. This technology could help us save much energy

    A new study suggests a simple getting-to-know-you exercise might improve classroom relationships. The teacher-student relationship affects every aspect of the educational experience. When students don't feel safe and respected by their teacher, they are less likely to devote themselves to their education. And when teacher feel distanced from their students, it is nearly impossible to walk into the classroom each day actively, let alone encourage motivation or investment in students.

    Hunter Gehlbach, a professor, explained that his research is primarily concerned with social perspectivetaking(换位思考), or the ability to understand what drives the people around us. As he explained, "My focus is classrooms and social perspective-taking--figuring out the thoughts and feelings of others seems important. We want teachers to be able to engage in this process and figure out the thought process of students as much as possible, in order to understand where and why they are making mistakes."

    Gehlbach and his colleagues gave 315 students and 25 teachers a "getting-to-know-you" survey of 30 items at the beginning of a school year. The researchers matched similarities between the teacher and the student, and then showed those similarities to the teachers and students. Five weeks later, the researchers returned to start a more indepth survey of both students and teachers, and to measure their opinions of their relationships and the classroom experience as a whole. The second survey showed that when teachers and students know they have five things in common, relationships and educational outcomes both improve.

    Gehlbach explained that the similarities he and his colleagues established were not based on personal information, but on shared preferences. Gehlbach explained: one of the biggest surprises in reading the similarity research was how little some of the similarities were that caused positive feelings towards others.

    Though Gehlbach's study has limitations, he is encouraged by the results and eager to explore the phenomenon further.

Steps for a Successful College Application

    When it comes to getting into the college of your choice, your college application is the most important tool you have in your hands. {#blank#}1{#/blank#}, while a bad one can land you at the bottom. Keep the following tips in mind when you are going through the college application process and you'll be on the road to admission.

    Be Prepared

    {#blank#}2{#/blank#}, carefully look over all the questions and requirements. Dedicate a page to each college with a checklist of everything you'll need to submit, such as transcripts, recommendations, the essay, copies of awards/certificates, etc.

    {#blank#}3{#/blank#}.

    Former Records Technician, Carmen Huff, says the best thing students do is to get their applications early—or at least by the deadline. Colleges and universities receive so many applications that they don't have the time to accept late ones. The more time you give the college or university to process your application, the more time you'll have to deal with any problems that might arise, Huff says.

    Watch Your GPA and Test Scores

    This is the first thing that most universities look at. For example, most four- year colleges don't have a GPA requirement, but top Ivy Leagues(常春藤联盟) usually only accept students with a 3.5 or higher GPA. However, if your GPA is weak, don't give up applying. {#blank#}4{#/blank#}.

    Write an Amazing Essay

    A great essay can help tip the balance in your favor. {#blank#}5{#/blank#}. Many colleges require two essays, one short and one long. What you write not only shows how literate you are, but also provides the reader with an impression of your values and beliefs.

A. Be On Time

B. Be Patient and Determined

C. When you have a test or an exam

D. When you first receive the application

E. A great application can zip you to the front of the line

F. So, take the time to think your essay through carefully

G. Instead, be sure to emphasize your other good qualities such as any awards or community involvement

    A survey has shown that what you do on a plane can be determined by which nationality is listed on your passport.

    According to the results of an international passenger survey, Australians are the biggest drinkers on board with 36 percent choosing to down the hatch, compared to 35 percent of Americans and 33 percent of Brits.

    The Airline Passenger Experience Association ( APEX) spoke to around 1500 people, aged 18 and older, who have travelled by plane at least once during the last three months and were living in the United States, United Kingdom, Germany, Japan, China, Singapore, Australia or Brazil.

The results found Chinese travelers are most likely to nod off once the sea-belt sign switches off. They are also the first to reach for their credit card for some in-flight shopping and the biggest fans of gaming. Americans on the other hand like to use their time in the air more productively —when not drinking —choosing to work while flying a 350000 feet.

Meanwhile, Brits and Germans are the best at making chat with random strangers — spending 50 percent more time than any other nationality. Comparatively, Brazilians conduct their conversations online via e-mail, messaging apps or social media.

    Despite plane food having a bad reputation, seven out of ten interviewees said they were happy to eat up on the selection in-flight snacks and meals. In-flight magazines were also popular with four out of five passengers claiming to read them.

    The international flyers did however express their desire for better in-flight entertainment. “The industry has greatly improved the comfort, entertainment and onboard service, and passengers are accepting those improvements,” said Russell Lemieux, APEX executive director. “At the same time, passengers are demanding more from their air travel experiences which will drive more improvements touching all aspects of the journey,” he added.

    MacDonald's will soon remove cheeseburgers and chocolate milk from its Happy Meal menu to set a good example in offering a healthy diet for kids at its restaurants.

    Customers can still ask for cheeseburgers or chocolate milk with kids' meal, but MacDonald's said that not listing them would make them less likely to be ordered. Since it removed soda from the menu four years ago, orders for it with the Happy Meal have fallen by 14%.

    As MacDonald's is known for getting more business from families with children, it is especially important for it to offer a healthy diet instead of junk food. And the Happy Meal is a key part of that. The Happy Meal has long been a target(目标) of health advocates(拥护) and parents who link it to childhood obesity(肥胖症). To get rid of its bad image, MacDonald's has made many changes on the Happy Meal over the years, including cutting the size of its fries and adding fruit.

    Recently, the company replaced its former apple juice with a new kind of juice that has less sugar. MacDonald's wants all its Happy Meal choices to have 600 calories or fewer. It also wants less than 10% of the meal calories to come from fat and added sugar. The cheeseburger and chocolate milk didn't meet those new standards. However, MacDonald's is trying to cut sugar from chocolate milk and believes it'll be back on the menu eventually.

    There will be other changes. For example, bottled water will be added as a choice to the menu, but it will cost extra. Currently, the Happy Meal menu lists milk, chocolate milk, and apple juice.

    For international restaurants, MacDonald's said that a least half of the Happy Meal choices available must meet the new standards. Some MacDonald's restaurants are adding new menu items to obey. For example, In Italy, a grilled chicken sandwich was added to the Happy Meal menu.
