You can't always predict a heavy rain or remember your umbrella. But designer Mikhail Belyaev doesn't think that forgetting to check the weather forecast before heading out should result in you getting wet. That's why he created lampbrella, a lamp post with its own rain sensing umbrella.

    The designer says he came up with the idea after watching people get wet on streets in Russia. “Once, I was driving on a central Saint Petersburg street and saw the street lamps lighting up people trying to hide from the rain. I thought it would be appropriate to have a canopy（伞蓬）built into a street lamp.” he said.

    The lampbrella is a standard-looking street lamp fitted with an umbrella canopy with a built-in electric motor which can open or close the umbrella on demand. Sensors（传感器）first ensure that it starts raining and the motors open up in response to their sensors and then people can protect themselves from the rain under the canopies.

    In addition to the rain sensor, there's also a 360° motion sensor on the fiberglass street lamp which detects whether anyone's using the lampbrella. After three minutes of not being used, the canopy is closed.

    According to the designer, the lampbrella would move at a relatively low speed, so as not to cause harm to the pedestrians. Besides, it would be grounded to protect from possible lightning strike. Each lampbrella would offer enough shelter for several people. Being installed（安装）at 2 meters off the ground, it would only be a danger for the tallest of pedestrians.

    While there are no plans to take lampbrella into production, Belyaev says he recently introduced his creation to one Moscow Department, and insists his creation could be installed on any street where a lot of people walk but there are no canopies to provide shelter.

    Bryan Laubscher, one of the world's leading astrophysicists, who study the physics and chemistry of the stars, planets, etc, is developing an invention called the Mars Elevator. To form a picture of this, you may want to imagine the story of Jack and the Beanstalk (《杰克与魔豆》). This is the story of a boy who grew a beanstalk that reached the heavens. Jack climbed the stalk and entered another world. The space elevator is similar but of course much more high-tech and better yet, it is real!

    Astrophysicists are designing a steel-like cable (缆绳) that will be connected to a platform (平台) in the ocean. This cable is designed to be pulled up into space, where it will then be connected to a space station. People will be able to travel up and down this elevator by the year 2020. There will be a number of space elevators so that both tourists and businesses can travel into space. To get there, space tourists will simply travel to the nearest ocean elevator entrance. The trip up into space will take about a week. When they arrive, space tourists will be inside a space station and will be able to stay there. There are other alternatives, too. Astronomers think it will be easy to travel from the space station to the moon, where space tourists can stay in a moon hotel — which is now being designed.

    The future looks bright for space tourists. It also looks bright for industry and scientists. Mining companies will travel to space to mine elements (元素) that are rare on Earth. Energy scientists will travel to space to set up space solar panels, which will collect a huge amount of energy from the sun and shoot it back to Earth where we can use it to heat our homes and meet our energy needs.

    Two heads are better than one. It means that two people working together have a better chance of solving a problem than one person alone. But not everyone likes working in a group.

    There can be a number of reasons why people dislike group work. Some may feel nervous or uneasy in group situations. Others might have had a bad experience with individuals who did not work well as a team. Another comment is that teachers or instructors fail to provide roles for group members. This may create a situation where everyone or no one wants to lead. Whatever the issue, the result is the same: the group does not realize its goal.

    Cooperative (合作的) learning is an educational method that can help to solve this problem. There are many methods of cooperative learning. Today we will talk about one: giving each person in a small group a specific duty to reach a shared goal. For example, if learners are divided into groups of four people each, their roles might be: leader, writer, checker and speaker. This structure helps ensure that everyone takes part equally in group work and allows each member to play a meaningful part in completing the shared goal.

    Before dividing learners into groups, it is a good idea for the teacher or club's instructor to first have knowledge about the language skill levels of participants. The goal is to make each group a mixture of higher- and lower-level language learners. Putting too many people with similar skill levels together could make the work too difficult or easy. Role cards can be a helpful tool in this method of cooperative learning. Their purpose is to remind learners of each person's role.

    Before the cooperative activity, the role of the teacher or activity instructor is to explain two things to the group: the main job for the activity and how the cooperative roles work. The person in charge may appoint these roles or let the English learners choose them. Then, during the activity, the instructor's job is to watch the groups and provide more guidance when needed. After the activity, the instructor may wish to provide feedback to groups on their work and their use of cooperation.

    With this cooperative learning method, you can say that four heads are better than just one.

    Some places in the world have strange laws. It's important for you to know about them before going there.

    Whoever likes to chew gum (口香糖) may have to leave Singapore. The government really wants to keep the city clean and will fine you for chewing gum.

    Before you leave for the United Arab Emirates you'd better make sure you aren't visiting during Ramadan (斋月). During that time you aren't allowed to eat or drink in public. Tourists have been fined up to $275 for drinking in public.

Lovers spend so much time kissing each other goodbye at train stations that trains often start late. This law—no kissing your lover goodbye at train stations—is rather old, and isn't in use today in France.

In Thailand it's against the law to drive a car or motorcycle without a shirt on, no matter how hot it is. Punishments are different in different areas and can include warnings and tickets costing about $10. No joke —the local police will stop you.

    Studies in Denmark have shown that cars with their headlights on are more noticeable by other drivers than those with their headlights off. Drivers there are required to leave their headlights on even during the day, or they may face a fine up to $100.

    Do you often buy things using coins? Don't do it in Canada. The Currency Law of 1985 doesn't allow using only coins to buy things. Even the use of the dollar-coin is limited (受限制的). The shop owner has the right to choose whether to take your coins or not.

    Make sure you know about these laws before your next trip. Better safe than sorry.

    TV, iPads, and computers are fun and sometimes educational, but many people think the technology is bad. My parents let me watch one or two shows or play a game on the iPad for an hour, but then make me find thing else to do, like read or draw a picture. They say that too much screen time won't help me become smarter.

    I think that it is okay to watch TV, but not too much. And some of my friends agree.

    "A tiny bit of screen time is okay," Mateo J., 7, said. "But too much of it is not good for your brain."

    Though my friends and I sometimes complain (抱怨), we think that it's good our parents limit our screen time.

    "Our parents should limit our technology time because otherwise you might get carried away and not even know that you've stayed inside all day watching TV," Naomi J. , 9, said.

    The American Academy of Pediatrics(AAP) used to recommend (推荐) that parents let kids have about two hours of screen time per day, but in 2016, they started recommending that parents of kids 6 and older decide for themselves how much time is okay, as long as the shows and games are appropriate. The AAP still says that kids 2-5 years old should have only about one hour of screen time per day, and kids under 2 no screen time at all. The AAP says that media you've stayed inside all day in all forms, including TV, computers, and smartphones, can affect how children feel, learn, think, and behave. However, parents are still the most important influence.

    I think TV shows like Brain Games and Cupcake Wars are inspiring. I've even learned some magic while watching Brain Games! Video games can be educational, as some TV shows are about nature, and other shows have useful messages. But some games and shows have bad things in them, like smoking.

    You can play outside instead of watching TV. Find other things to do. You don t have to be or screens all day.

The new garbage sorting regulation has taken effect in Shanghai starting July 1. Many citizens are still confused about the classification of the four different types of trash. Thankfully, authorities have released an official guideline to clarify the new rules.

The guideline, published by the Shanghai Greenery and Public Sanitation Bureau, provides a rather clear definition on the four kinds of waste: recyclable waste, hazardous (有害的) waste, household food waste and residual (剩余的) waste.

Hazardous waste, as the name suggests, includes assorted poisonous materials like used batteries, light bulbs, out-of-date medicines, paint and pesticides.

Household food waste, which is translated to "wet trash" in Chinese, refers to food leftovers, rotten food, pet food, fruit peels, remains of TCM herbs (中药) and flowers.

Paper, plastic, glass, metal and textiles (纺织品) are counted as recyclable waste.

The definition of residual waste is a little confusing. Anything that is not listed above belongs in this category.

As specific as the new guideline is, residents still have a hard time sorting trash correctly and are finding it challenging to memorize them all. For instance, both plastic bottles and bubble tea or coffee cups are plastic materials. However, the former falls to the category of recyclable waste and the latter belongs to residual waste. To save the hassle, some netizens have come up with their own ways to sort trash.

"We should do this from a pig's angle," commented one netizen. "Those edible (可食用的) for pigs are household food waste. Those even pigs don't want to eat are residual waste. If a pig consumes something and dies of it, then something must be hazardous waste. Those which can be sold and the money we gain can be used to purchase pigs are recyclable waste." The new regulation has gone into effect on July 1. Those who do not sort their trash properly will be fined RMB200.
