Task 1

Many people have long dreamed of being able to fly around as simply as riding a bicycle.Yet the safety and strength of a flying bike was always a big problem.Over the past 10 years,developments in technology have moved the dream of personal flying vehicles closer to reality.Now,two groups of inventors say such vehicles may be available soon.

The British company Malloy Aeronautics has developed a prototype(原型)of its flying bicycle.Grant Stapleton,sales and marketing director of Malloy Aeronautics,says the Hoverbike is able to get in and out of small spaces very quickly.“It can be moved across continents very quickly because it can be folded and packed,”he adds.

Mr Stapleton says safety is the company's main concern.He says the designers solve the safety issue by using overlapping rotors(转动部件)to power the vehicle.

The company is testing a full-size prototype of the Hoverbike,which will most likely be used first by the police and emergency rescue teams.

In New Zealand,Martin Aircraft Company is also testing a full-size prototype of its personal flying device,called the Jetpack.It can fly for more than 30 minutes,up to 1,000 meters high and reach a speed of 74 kilometers per hour.

Peter Coker is the CEO of Martin Aircraft Company.He says the Jetpack is built around safety from the start.In his words,reliability is the most important element of it.“We have safety built into the actual structure itself,very similar to a Formula One racing car.”

The Jetpack uses a gasoline-powered engine that produces two powerful jet streams.Mr Coker says it also has a parachute(降落伞)that would be used,if there should be an emergency.“It starts to work at a very low altitude and actually saves both the aircraft and the pilot,”he adds.Mr Coker says the Jetpack will be ready for sale soon.

Task 2

Why walking makes you a better worker

We're busy at work,distracted(分心)by technology,and often live in urban environments far from wild spaces.__1__The average American,for example,spends about 90% of their life indoors.But what happens if we make time for an hour outside each day?

__2__You'll have to stand up and move,which is beneficial if most of your day involves sitting in front of a screen.Research shows short breaks can improve work enthusiasm,and a quick break in natural light will deliver a shot of Vitamin D.

There's also a lot of work on the mental benefits of being in nature—on the state of being happy and on your brain's ability to make sense of life. “When people are all out in nature，even in urban nature,people tend to have more positive emotion and energy than when they are indoors._ __3__”says Lisa Nisbet,associate professor at Canada's Trent University.

The idea that nature is good for us has been gaining ground since the 1980s. _4__Afterwards shinrin-yoku,the Japanese concept followed that absorbing the atmosphere in forests can benefit your health.Researchers of shinrin-yoku have since found plenty of physical and mental benefits,while global studies suggest time in nature can,for example,restore our ability to focus,increase creativity,and even help us live longer.

Of course,many of us live in cities with no ready access to forests or wilderness. _5__Various studies have shown that green environments in cities have beneficial effects.

A.We also don't get out much.

B.But it doesn't have to be a forest.

C.People can get to a forest for a hike.

D.In other words,people are happier in nature.

E.There are some obvious benefits to go outside.

F.Green and blue spaces are better than busy city streets.

G.First came the theory that humans have a basic desire to connect with nature.

Task 5

阅读下面短文,根据其内容写一篇60词左右的内容概要。

Alipay Ant Forest has been awarded the United Nations'highest environmental honor—the UN Champions of the Earth award.The statement was issued by UNEP(联合国环境规划署)on September 20.

The Ant Forest was started in the Alipay app in August 2016.It encourages users to adopt lowcarbon activities—such as paying online and walking or taking buses to work instead of driving.Such behavior produces virtual “green energy points”.With enough energy points,users can grow a virtual“tree” on their mobile phone.Then the virtual tree is planted by Alipay in areas that need reforesting.

By August 2019,Alipay Ant Forest has attracted over 500 million users.Their low-carbon behavior has resulted in 122 million trees in arid areas in China,including regions in Inner Mongolia,Gansu,Qinghai and Shanxi.The influence has also traveled beyond China.Inspired by Alipay Ant Forest,the Philippines'leading mobile wallet service GCash added GCash Forest to its App in June 2019.Local users are encouraged to contribute to reforestation and environmental protection by adopting low-carbon activities in their daily lives.

“Alipay Ant Forest shows how technology can change our world,” said Inger Andersen,executive director of the UNEP.“Although the environmental challenges we face are disappointing,we have the technology and the knowledge to defeat them,”she said.

Champions of the Earth is the UN's flagship global environmental award.It was established in 2005 to recognize outstanding figures that have had a positive effect on the environment.

“We are truly honored to receive this Champions of the Earth award,” said Eric Jing,Chairman and CEO of Ant Financial.“Alipay Ant Forest reflects our belief that technology can and should be used for social good.Its popularity shows that the public is ready to take action to fight climate change,”he said.
