Each year,hikers and mountain bikers get lost or injured in the

wilderness.Search and rescue efforts can involve 20 or more people.But a new

“smart” drone(无人机) can follow hiking trails(小路) without a pilot’s

assistance.This could allow rescuers to search more efficiently. Scientists outfitted a craft with a single camera.As the drone’s “eye”,the

camera pointed forwards.But having an eye wasn’t enough.The drone also

needed a “brain” to understand what it was seeing.And that brain would have to

recognize what constitutes a trail.Camera images,however,can be very difficult for a

computer to interpret,study leader Alessandro Giusti notes.So he and his team used

photos of forest trails to train their drone’s neural network(神经网络).

They attached three GoPro cameras to a single headband.One camera pointed

straight forward.The other two were directed 30 degrees to the right and left of the

centre.A hiker put the package on and then hit the trails in a forested part of

Switzerland.Over several weeks,the cameras recorded a total of 8 hours of video

covering 7 kilometres of trails.

The researchers then divided the video into individual still images to train the

neural network.The network learned to identify what a trail looked like.The team

then tested the program with unused images from the video.The computer did a

slightly better job than the people had in correctly classifying the images.This

meant the drone was ready to navigate the real world on its own.Giusti and his

team took their now “smart” device to a forest with trails that had not been used

in the drone’s training.It flew along the path,constantly adjusting its direction

based on the images coming in through its camera.

The drone didn’t perform as well in real-life as it did in the lab,Giusti

admits.That’s because the drone’s camera took lower-quality images than the

cameras that had been used to train it.As a result,the images being taken by the drone looked different,he explains.This confused its neural network.

“It’s an exciting use for neural networks,” says Christopher Rasmussen,a

computer-vision scientist who was not involved with the study.“However,the

problems faced in the experiments show that there are still some important issues

to be worked out.”

1.The “smart” drone has been created in order to help .

A.find travelers who get lost

B.ensure the safety of travelers

C.deliver necessities to travelers

D.show travelers the way to a place

2.While being tested to classify the images in the lab,the computer .

A.did as well as the people

B.did a lot better than the people

C.did much worse than the people

D.did a little better than the people

3.Why didn’t the drone perform well in the forest?

A.The light in the forest was very poor.

B.The trees or bushes covered the trails.

C.The drone couldn’t fly very low there.

D.The pictures taken were of poor quality.

4.What is Christopher Rasmussen’s attitude towards the results of the

experiments? A.Critical. B.Doubtful.

C.Objective. D.Optimistic.

Shopping centres,stadiums and universities may soon have a new tool to help

fight crime.

A California company called Knightscope says its robots can predict and

prevent crime.Knightscope says the goal is to reduce crime by half in areas the

robots guard.

William Santana Li is the chief executive officer of Knightscope.He says,“These

robot security guards will change the world.Our planet has seven billion people on

art of the north.

out on public view.It's also about creating a wonderful description for the north

through the lens(镜头)of art and furthering the museum's mission of expanding

awareness of the north，its landscape and cultures.

An expanded museum will：

·Provide greater public access to the museum's art collection

landscape and people

Persuasion is to convince someone to agree with you, just like art which also calls

for special techniques to accomplish. According to the ancient Greeks, there are three

basic tools of persuasion: ethos, pathos and logos.

Ethos is a speaker’s way of convincing the audience that he is trustworthy,

honest and reliable. One common way a speaker can develop ethos is by explaining

how much experience or education he has in the field. After all, you’re more likely to

listen to advice about how to take care of your teeth from a dentist than a fireman.

Pathos is a speaker’s way of connecting with an audience's emotions. For

example, a politician who is trying to convince an audience to vote for him might say

that he alone can save the country from a terrible war. These words are intended to fill

Winston Churchill is probably the most popular British prime minister ever.

Having served as a soldier and politician, he is often considered among the greatest

of Britons. While his heroic stand against the Nazis is well know, there are still a few

facts about the popular politician that might surprise you.

His Cigars

The classic image of Winston Churchill includes a giant cigar stuck between his

lips. Churchill developed his love of cigars as a young man, when he traveled to Cuba.

For the rest of his life, he smoked eight or nine cigars every day. However, he almost

never took a puff(吸，抽), preferring to chew on the end until it went out, then relight

it and start again. To prevent the cigar becoming soggy (湿软的), Churchill invented

the ＂bellybando＂, a strip of brown paper which could be glued around the end.

A new study has found the amount of antibiotics given to farm animals is expected

to increase by twothirds over the next 15 years. Researchers are linking the growing

dependence on the drugs to rising demand for meat, milk and eggs. The researchers warn

the drugs could quicken the development of antibioticsresistant (耐抗生素的)infections. Such infections are already a major public health concern in the United

States.

Experts say when people stop living in poverty, the first thing they want to do

is eat better,rather than earn more money. For most people, that means their diet should

contain more meat. Increasing prosperity in Asia has meant people there are eating nearly

four times as much meat, milk and dairy products as they did 50 years ago.

To meet that demand, farms have put many animals into smaller spaces. As the animals
