Do you find yourself reaching for just one more cup of coffee to get through the day?Are you tired of being tired?Instead of relying on things like coffee or sugar for energy,get happy by eating more foods that give you energy through nourishment.Here are four foods that can help improve your energy levels.

    Hemp Seed

    A complete protein,rich in fiber and omega-3s,hemp is a great low-glycemic（低胰岛素）addition to any diet.The glycemic index (GI) is a measurement of how fast the carbohydrates in food are broken down into glucose（葡萄糖）and how much it will affect your blood sugar.Fiber,fat and protein all lower the GI of a food,which is why hemp seeds (along with nuts,seeds,whole grains and legumes) are low-glycemic.Look for hemp seed oil for salad dressing,and hemp seeds to be added into salads.

    Soaked Almonds

    Raw almonds are nutrient dense,and soaking them releases（释放）higher nutrition potential.Soaking increases vitamin levels and removes the enzyme（酶）inhibitors that slow down digestion.I soak my almonds in water overnight (at least eight hours) and then dry them.

    Quinoa

    It is 20-percent protein,making it a balanced source of carbohydrates.Even though you feel like you're too busy to make home-made meals,quinoa is a fast food that cooks in less than 15 minutes.

    Green Tea

    Caffeine from green tea feels steadier and less sharp than the spike and crash with caffeine from coffee.This is likely because green tea contains L-theanine,a kind of acid found in tea that helps promote relaxation.      .

                                                                       Balloon Volleyball

    It's a rainy, dark day and there's nothing to do. You don't feel like sitting quietly but you are not allowed to make a lot of noise. What can you do for fun? Try balloon volleyball.

    Items needed for this game: a balloon (or two, in case the first one bursts), some ropes, two chairs, at least two people and a room.

    Set up the room. If you're in the living room, or a family room, be sure to move all the furniture out of the way. Get two chairs and set them in the middle, outer edges(边缘)of the room. They should be at the same place where you put a volleyball net. Turn them so that the seat is facing the wall, not the “playing” space. Tie the rope onto the top of the chair, and run the rest of the rope to the other chair. Now tie it on this chair at the same place as the first chair. You can decide the “out-of-bounds”(出界) lines, if you want to have them, but they really are not necessary in this game.

    Blow up the balloon. Choose sides. You will play this game on your knees (at least until they start hurting and you want to stand). Each side must get the balloon over the rope in three hits. If it does not get over, the other side gets the balloon and a point. This game becomes more difficult because you must play without talking.

    You can also add other rules to make it more difficult; for example, you can only use your left hand or only your right hand to hit the balloon.

    Continue playing until one side gets 10 points. You can make your game longer or shorter by changing the number of points it takes to win.

    This is a fun way to get your energy out, have fun, and not make too much noise on a rainy, stay-in-the-house day.

    Getting more followers is something we usually associate with social media or micro messaging apps. But soon we could all have a new type of follower—a robotic one.

    Dozens of robots and technology fans gathered in Boston, US, earlier this month for the Robot Business conference. The latest developments in the world of robotics were shown to the public, and this time the trend was robots following people.

    Perhaps the most exciting development on show was the ability of drones (无人机) to follow you from the air, acting as your own personal cameraman or photographer. One example is 3-D Robotics' Iris+ drone, developed by a US-based company.

    The drone is fitted with cameras and has a “follow me” function. It connects with your GPS-enabled Android device, like a mobile phone. Then it flies and follows you around, shooting action film of you from above. The software in the drone makes sure that you're always in the center of the frame.

It can keep working for 15 minutes, as long as there aren't too many trees for it to crash into. This could be exciting for anyone who loves action sports or wants to be the star of their own short film.

    But what if you want to be one of those celebrities (名人) who have helpers carrying all their bags and doing all their chores? A robot called Budgee can help.

    Budgee, made by 5 Elements Robotics, is literally a basket on wheels.It is designed to help elderly and disabled people, or simply anyone who doesn't have enough arms for grocery bags, Wired magazine reported.It can carry up to 22.7 kg of items.

    To make Budgee follow them, its owner will have to wear a small device and use an app to set the distance between themselves and the robot.Budgee even sends a text message when it can't keep up with its owner.

     “I want you to look at the robot like he's your buddy, he's your friend. There's a relationship you develop with the robot,” Wendy Roberts, CEO of 5 Elements Robotics, told gigaom.com.

    It might not be quite the same as robotic assistants we've seen in movies such as Disney's Wall-E, where robots cater for our every need, but that idea doesn't seem quite so far-fetched now.

    Humans and gorillas shared evolution for 23 million years. Their paths separated only six million years ago. Research on how gorillas communicate can help us understand human language development.

    Understanding how the brain works helps us see a connection between language development and non-verbal signs. These signs or movements include things like the way we move our hands or bodies or the different expressions our faces have in different social situations. A new study on gorillas showed that the right side of the body is controlled by the left part of the brain and it is also the location for language development.

    Two cameras were used to film all of one ape's movements. One of the first results was that gorillas use their right hands more when they are doing actions with their heads or mouths at the same time. This shows that there is a connection between how our brain works and the reason we use one side of our body more than the other. In addition, we can use the results of the study and our knowledge about brains to help us understand more about how language first developed in humans.

    Dr Forrester, who did the study, says the results can be useful in other ways, such as understanding language development in children. For example, some children have serious illness called “autism” which can stop them communicating normally with people. It might be possible to use the same study method to find out which children have this illness when they are very young. Doctors will then be able to start treatment early.

    Although English is not as old as Chinese, it is spoken by many people around the world every day. English speakers are always creating new words, and we are often able to know where most words come from.

    Sometimes, however, no one may really know where a word comes from. Did you ever think about why hamburgers are called hamburgers, especially when they are not made with ham? About a hundred years ago, some men went to America from Europe. They came from a big city in Germany called Hamburger. They did not speak good English, but they ate good food. When some Americans saw them eating round pieces of beef, they asked the Germans what it was. The Germans did not understand the question and answered. "We came from Hamburger." One of these Americans owned a restaurant, and had an idea. He cooked some round pieces of beef like those which the men from Hamburger ate. Then he put each between two pieces of bread and started selling them. Such bread came to be called "hamburgers". Today "hamburgers" are sold in many countries around the world.

    Whether this story is true or not, it is certainly is interesting. Knowing why any word has a certain meaning is interesting, too. The reason, for most English words, can be found in any large English dictionary.
