What will the future world be like? Many people are glad to give their _______ .Here are two imaginations about the world of   _______ . When people talk about the future, we like to think that will have our own personal flying car.     We   would     fly     at     480     kilometers     per     hour,     avoiding     traffic lights, _______ roads and speeding tickets. However, some people point to the disadvantages of flying cars. One big problem is what will happen if   the   flying cars   _______   ?   Then there will   be   problems with traffic control. Also,   if   they become popular, there will surely be too much air traffic. So it seems that flying cars will face more than a few problems if they are to get off the ground .Imagine you have your own Ironman   _______   . Several companies are trying to build a practical robot “exoskeleton" .This is a suit of robot arms   and legs which follows your movement. It will allow the wearer to lift heavy objects, walk a long way and even punch through walls! It is   _______ in   many   ways, especially for people with disabilities. This suit might help people to walk   again   after _______   or   injury.   But   the   disadvantage   at   the   moment   is the _______   . Even a simple suit can cost hundreds of thousands   of   pounds. Another problem is battery life. A suit like this needs a lot of   _______ and batteries only last about 15 minutes at the moment. One other problem is that a badly programmed robot wearer. You wouldn’t want   your   robot leg   or   arm bending suit could ________ the wearer if he wears it the wrong way.

So, in the future, we might be able to fly to work and lift every heavy things. But there are plenty of problems to solve before this will be possible

What are the best inventions this year? You can find some amazing things on the list in Times magazine.

Smart mug	It’s hard to keep coffee or tea warm,   especially in winter.   But this smart mug from USA company Ember Technologies can solve this problem. The mug is stainless steel（不锈钢）inside and white ceramic（陶瓷）outside. There is an app for   the mug that allows people to set the mug to a certain temperature between 48℃and 62℃.   Then,   the mug keeps your coffee or tea at that temperature for about an hour or even longer.
Social robot	Social robot Jibo,   a robot made by US company Jibo Inc, can talk to you. With a big,   round head and a big body,   Jibo looks like a cartoon character.   As soon as you say,   “Hey,   Jibo,”   it dances and turns to face you. When it talks to you, it moves its head and body to communicate with you. Although it has no eyes or mouth, Jibo uses emojis（表情包）, such as a smile icon, to show feelings.   All the features make it seem like a real human. Jibo can also do some easy things, like taking photos or reading the news to you.
iPhone X	The iPhone X is a “dream come true”.   The biggest highlight is the face ID,   which allows users to unlock their phone and pay for things just by looking at their smartphone. Another change is wireless charging（充电）. Instead of using a charging cable, users can simply put their phone on a wireless charging pad. Another fun feature   allows users to create their own emojis. Just by looking at the screen, users can see live images of themselves.
Drones（无人机）	Spark is a new type of drone made by a Chinese company in Shenzhen called DJI.   It helps people take photos and videos. Spark might be the smallest drone ever made.   It is as big as a tin of cola. The coolest part is that users can control the drone just by using hand gestures.   If   you wave your hand from left or right,   the drone will fly in the same direction.   When you want it to land, you just put your hand out.   The drone will come to you and land on your hand. This makes taking photos easier and more convenient.

Everybody hates rats. But rats may soon be man’s new good friend.

What happens after an earthquake? We send in rescue dogs. Why? Because they can smell people. Dogs save lives. They help rescuers to find living people. But dogs are big and they can’t get into small spaces. So now a new research project is using a smaller animal to save lives: the rat.

How does it work? First, the rat is trained to smell people. When this happens, the rat’s brain gives a signal. This is sent to a small radio on its back, and then the rescuers follow the radio signals. When the rat’s brain activity jumps, the rescuers know that someone is alive. The rat has smelled that person.

Although there are already robots which can do this job, rats are better. “Robots’ noses don’t work well when there are other smells around. Rats are good at that.” Rats can also see in the dark, they are cheaper and quicker to train than dogs, and unlike robots, they don’t need electricity!

The “rat project” is not finished, but a scientist says, “It would be great. A rat could get into spaces we couldn’t get to, and a rat would get out if it wasn’t safe.” Perhaps for the first time in history, people will be happy to see a rat in a building (but only after an earthquake, of course).

The weather is getting hotter and you'll be getting thirstier playing basketball or riding home from school. A cold drink may be just the thing.But be careful what you pour down your throat.Something that looks cool may not be good for your health.

There are plenty of so-called energy drinks on the market. Most of them have an attractive color and cool name. Their nutrition lists also contains various things from vitamins to ginseng(人参).Sounds great!

But after a careful check you may find that most energy drinks contain high levels of caffeine. These drinks are typically aimed at young people, students, busy people and sports players.

Makers sometimes say their drinks make you better at sports and can keep you awake.But be careful not to drink too much.Caffeine raises your heartbeat. Because of this, the International Olympic Committee has limited their use.The amount of caffeine in most energy drinks is at least as high as in a strong cup of coffee or strong tea.

Research by Australian scientists has found that many teenagers are affected by caffeine. The results of their survey show that 27 percent of boys aged 8～12 take in more caffeine than their parents.

There are potential( 潜在的)health risks linked to energy drinks. Just one can of energy drink can make you nervous, have difficulty sleeping and can even cause heart attacks.

Teenagers should be discouraged from consuming drinks with a lot of caffeine in them, an expert from the Australia Nutrition Foundation said.

Alfredo Moser is a Brazilian   worker who is skilled at repairing machines. His wife says her husband has always been handy at home and made tables and chairs. Alfredo has invented a way of lighting his house during the day without electricity.

He has been using plastic bottles filled up with water and   a   little   bleach( 漂白剂) to provide dark rooms with light for many years. And the idea has now spread across the world. It is predicted that his   lighting   system, which works using refraction(折射) of the sunlight, will be fitted in over a million homes by the end of this year.

Alfredo used normal plastic drinks bottles that are often thrown away. The secret of the water in the bottles is the bleach added to water, which stops it turning green in the sunlight. Mr. Moser drills a hole in a   roof   tile   and then pushes the bottle in from below, keeping the bottle in place with polyester resin (聚酯树脂). Depending on the strength of sunlight, the light fills his home, and the bottles are just like electric bulbs of between 40   and   60 watts.

Alfredo came up   with   the idea   for   his   “Moser   light’’   during   one   of the blackouts in Brazil in 2002. He said only factories had power   in   his home city, in southern Brazil during the energy shortage.

The local supermarket and his neighbors’ houses are   using   Moser lights. He earned a few dollars, but his invention has not made him a rich   man. Now a great number of people admire what he is doing!

The First Robotics Competition (FRC) was held in Shenzhen. A total of 35 high-school student teams from China, the United Kingdom, Turkey, Poland and other countries joined the two-day contest with their hand-crafted robots.

The FRC is a world-class robotics competition that was first launched in the United States in 1989. It encourages students to improve their hands-on skills and creative capabilities.

There are strict rules, limited resources and an intense six-week time limit before the competition. Teams of student should raise money, design a team brand and improve their teamwork skills, as well as build industrial-size robots to compete. The rules of the game include two groups, and each group has three teams. The group with the highest score wins the game.

The seven teams who won the top prizes in the FRC Shenzhen Regional will take part in the First Championship to be held in the United States next month.

Yin Shifei, secretary general, said the competition not only enables students to improve their programming, decision-making and problem-solving skills, but also encourages them to cooperate and share with other people

According to Yin, a Shenzhen team invited over 40 left-behind children to the city to watch the FRC game because they wanted to make education more equitable. And the left-behind children can get fair education. These children's parents are migrant workers in Shenzhen, but they are left behind in their hometowns.

Shenzhen became the first city to host an FRC region in Asia last year, and another regional contest will be held in Shanghai this year.
