Major airplane manufacturers are now moving to develop the future of flight with electric planes and personal flying vehicles.
Boeing is one of those companies. It recently invested in Zunum Aero, a company working to build electric aircraft for commercial flights. Zunum is based in the northwestern U.S. state of Washington. It says it is hoping to revolutionize air travel by cutting flight times and greatly reducing costs.
By the early 2020s, the company plans to operate electric aircraft to carry 10-15 passengers on trips up to 1,100 kilometers. It says the cost of such flights could be as low as $ 25 each way.
Zunum noted on its website that, while America has more than 13,500 airports, 97 percent of all air traffic goes through just 140 larger hubs. By traveling through smaller airports, passengers can greatly reduce door-to-door travel time and avoid long security lines.
JetBlue was another major company to invest in Zunum. The head of JetBlue’s investment group, Bonnie Simi, said Zunum fits the airline’s desire to “seek new technologies to change the game.” She praised the company for developing “quiet, environmentally-friendly aircraft” for sustainable travel.
Zunum’s planes will be powered by two large engines at the back. The aircraft will be “hybrid-electric,” meaning they rely mostly on battery power, but also bum fuel when needed.
The goal is to eventually fly fully electric planes, although most experts believe this could take many years. This is because battery technology still has a long way to go to provide long-lasting power, but not be too heavy for the aircraft.
Other companies have released plans to release flying cars a lot sooner than that. Slovakia-based engineering company AeroMobil is preparing to show the world its latest model this week.
AeroMobii is showing the car at the Top Marques auto show in Monaco. No launch date or prices have been announced, but the company says it will be taking pre-orders this year.

C. Because planes won’t start without fuel. D. Because battery may not last long enough.
35. From the last two paragraphs, we can infer that .

B. Flying cars will appear on the market this year
C. The prices of flying cars are still unknown
D. Flying cars are more popular than electric planes

In today’s times, health problems like diabetes, cholesterol, and high blood pressure are not restricted to adults, but have become a common phenomenon among children too. 36
Due to this lack of activity and no control on the food they eat, many children suffer from the problem of obesity at a very young age. 37 Hence, it becomes the responsibility of the parents to teach children important ways to remain healthy.
At a very young age, teach the kids to eat all types of food, like fruits, vegetables, meat, etc. 38 Cultivate the habit of eating breakfast as it is said to be the most important meal of the day. Eating a healthy and nutritious breakfast helps their body to develop energy for the physical and mental activities of the day.
Indulging in daily outdoor games with friends is more than enough physical exercise for children. Parents should see to it that their kids do not spend their entire time in front of the television or playing video games. 39
40 Children require 9-13 hours of sleep, depending on their age group. Lack of sleep in children can cause problems like lack of attention at school, feeling sleepy during the day, poor academic performance, etc. Hence, parents must ensure that their children receive sufficient sleep.
Other than these tips, it is important to teach kids proper hygiene (卫生学) rules like regular washing of hands, brushing their teeth, etc., so that they are not affected by infections.

F. They should encourage them to take part in sports and other physical activities.
G. The main reason for this can be attributed to their like towards fast food and lack of activity.
