2 . Tracking wildlife is a tough job. Take the case of a one-eared leopard named Pavarotti.

Kasim Rafiq, a wildlife biologist at Liverpool John Moores University. “So I used to get up at the crack of dawn, follow his tracks and try and find him. So one day, I went out, and I was looking for him. And his tracks took me off road through this woodland area...and...”

Before he knew it, the wheel of his Land Rover was stuck in a deep hole. He wasted several hours getting it out. And then, on the way back to camp, he came across some local tour guides and their safari (观赏野兽的旅行) guests, who’d had way better luck spotting Pavarotti. “Basically, they laughed and they talked to me that they’d seen him that morning.”

Rafiq then realized that tourist wildlife sightings might be an untapped source of information about wild animals.

So he and his team worked with a safari lodge in Botswana to analyze 25,000 tourist photographs of wildlife. They compared those data to the estimates they made with traditional wildlife biology methods.

It turned out that the estimates from tourists’ photos were just as good as those gleaned (四处搜集) from traditional methods. And the tourists were actually the only ones to see elusive (难以捉摸的) leopards — the researchers would have missed the cats without the citizen science data. The results are in the journal Current Biology.

The idea is not to put wildlife researchers out of a job. “The reality is there are so many interesting things we still have to find out about these large carnivores (食肉动物) and so many conservation (保护) projects that need to be carried out that we don’t have the time or resources to do them all.” And tourist photos might help make sure that all the local carnivores are spotted.

Thanks for listening for Scientific American-60-Second Science. I’m Christopher Intagliata.

3 . Imagine a world where you move around in front of a personal computer in your own sound space. You listen to your favorite songs, play loud computer games or watch a movie — all without other people hearing the sound and without headphones.

That is the possibility presented by “sound beaming”, a new technology from Noveto Systems, an Israeli company. On Friday, the company introduced a desktop device that sends sound directly to a listener without the need for headphones or a special receiver.

Noveto Systems gave The Associated Press (AP) a chance to test its SoundBeamer 1.0 before its introduction. The AP’s Louise Dixon writes that listening to the device is like something from a science fiction movie.The sound seems so close that it feels like it is inside your ears while also in front, above and behind them.

Noveto expects the device will have many uses. Office workers could listen to music or conference calls without others hearing. People could play a game, a movie or music without waking up others in the same room. Because the device does not use headphones, it is possible to hear other sounds in the room clearly.

The device uses a 3-D sensing module that finds and follows the ear position of the listener. It sends ultrasonic waves (超声波) to create sound pockets by the user’s ears. The 3-D method creates sound on all sides of the listener, therefore the listeners feel completely transported into the scene.

By changing a setting, the sound can follow a listener around when he moves his head. It is also possible to move out of the sound beam's path and hear nothing at all.

While the idea of sound beaming is not new, Noveto was the first to launch the technology.

According to the chief executive officer Christophe Ramstein, a “smaller” version of the device will be ready for release to consumers next year.

B．The listener may hear sound only for him or her without using headphones.

C．The listener may enjoy songs or movies without being interrupted by others.

D．The listener may have the ability to pick up some special sounds.

2. What does Louise Dixon think of SoundBeamer 1.0?

A．Amazing.	B．Impossible.
C．Strange.	D．Meaningful.

3. How does SoundBeamer put sound in the listener's head?

A．It places the listener on the scene to hear the sound.

B．It fixes a sound beam’s path which can not be changed.

C．It follows the listeners around to send and receive sounds.

D．With 3-D tracking technology, it sends ultrasonic waves to the target listener.

4. What is the purpose of the passage?

A．To promote the SoundBeamer.	B．To introduce a new sound device.
C．To recommend new headphones.	D．To explain a technical phenomenon.

4 . How far would you go to make a good impression at a new job? A college student in Alabama walked 32 kilometers in the dark to get to his new job.

The story begins with Walter Carr's car breaking down the night before starting a new job. Carr was unable to find a ride. So, he figured out how long it would take to walk from his house to the job in Pelham-32 kilometers away. He left at midnight so that he could make it to the customer's house by 8：00 am the next morning.

Pelham police saw him walking along a highway at 4-00 am. So, they stopped to see if he needed help. After hearing his story, they took him to a restaurant for breakfast and then to a church where he could safely wait until 8：00 am. The police then took Carr to the home of customer Jenny Lamey. Lamey said that even though Carr had just walked the entire night, he refused her offer to rest. He just wanted to start working. While he worked, he talked with the customer, telling her how much he liked her kitchen.

Jenny Lamey later wrote this on Facebook："I just can't tell you how touched I was by Walter and his journey. He is kind and cheerful and he has big dreams! He is hardworking and tough. " She then started a GoFundMe page to help Walter with money to get his car fixed. When the CEO of Bellhops, Luke Marklin, learned of Carr's story, he drove from Tennessee to Alabama to give Walter his own 2014 Ford Escape.

Walter Carr's story touched many others around the United States. Within a few days, people gave over $ 73 ,000 to his GoFundMe page. Carr has decided to give a part of the donations to the Birmingham Education Foundation. And he has received more offers for jobs and scholarships for schools.

7 . China will have the most 5G connections of any nation by 2025, according to a new study, while Europe will fall behind Korea, the United States and Japan in terms of 5G penetration(渗透)by that year.

5G is the fifth generation of network technology. It is expected to bring unbelievable speeds to Internet users, with some operations running 10 times faster than on 4G networks. 5G is also expected to unlock the potential in a lot of new services, including artificial intelligence, science of robots self-driving cars, and the Internet of things.

The GSMA said that China's three major mobile operators-China Unicorn, China Mobile, and China Telecom-are already moving ahead with 5G networks. While most nations will have 5G by updating existing foundations, the study noted that China plans to build part of its 5G networks.

One of the most distinguishing(显著的) factors between Chinese mobile operators and those in the rest of the world is the intention to erect the new and independent 5G networks. That is, China is determined to build a completely advanced 5G. The high cost underlines China's seriousness about paying whatever it takes.

Korea will lead the world in terms of 5G penetration in 2025, when 66 percent of the nation's total connections will be 5G, according to GSMA. This compares to 50 percent in the US, 49 percent in Japan, 36 percent in China, 30 percent in Europe, and a global average of 18 percent. Out of the five economies leading on 5G, Europe will have the lowest participation in 2025, as the area is moving more slowly in having its 5G networks.

1. What will 5G bring?

A．A completely new pattern for daily life.

B．Excellent networks and national safety.

C．Amazing speeds for public transportation.

D．Realizing the potential in many new services.

4. What can we infer from the last paragraph?

A．More than half Koreans use 5G in 2025.	B．Chinese cannot own 5G in 2025.
C．Only five countries will have 5G in 2025.	D．Europe will pay little attention to 5G in 2025.

8 . Though many people think of summer as a time to slow down and enjoy a vacation, it can also be the perfect time to make money or get experience. Here are some good summer jobs for you.

Survey-taking

Survey-taking is a way to make money during your summer holiday, especially if you live in an area that doesn’t have many chances. With a computer or smartphone, you can sit on your sofa and search for survey sites such as Surveys On The Go, InboxDollars or Swagbucks. Without much effort, you can start making money for your opinions. However, the ease of use comes with a low earning potential.

Food Delivery(递送)

If you enjoy driving, you can use your car to deliver food. You can sign up to deliver food from restaurants with services such as Uber Eats, DoorDash and Grubhub. Another choice is delivering daily used goods with services such as Postmates, Shipt and Instacart. The earning potential for delivery can be higher than for other jobs because customers often give tips. The disadvantage is that these jobs require you to put in more time.

Photo Applications

If you go to the mall, you can use an app such as Field Agent or Gigwalk to make money by taking pictures of products in stores. See any help-wanted signs in the store windows? Take a picture and get paid for each one you find.

House Sitting and Pet Care

Summer is a time when people take vacations and may need someone to look after their homes or pets. Services such as HouseSitter and MindMyHouse connect homeowners with proper house sitters(看房人). For animal lovers who would rather care for someone’s pet while they are away, you can turn to services like Rover.

1. What do we know about making money through Survey-Taking?

A．It’s interesting.	B．It requires little effort.
C．It takes much time.	D．It requires special knowledge.

2. Why is the earning potential for Food Delivery higher than for other jobs?

9 . Baby bats learn language from peers (同伴) in their social group, and will adopt the group’s dialect, or accent, instead of their mother’s, researchers said on Tuesday. The findings shed new light on crowd-learning of language, a skill thought to belong mainly to humans and just a few other mammals. It also shows that bats are different from songbirds, which tend to learn songs by copying one of their parents. “The ability to copy vocalizations (发音) from others is extremely important for speech learning in humans, but it’s believed to be rare among animals”, said lead author Yossi Yovel of Tel Aviv University.

For the study, researchers captured 14 pregnant Egyptian fruit bats. They separated them into three different bat social groups, where they raised the young bats with their mothers. Each bat group was exposed to a different recording of bat vocalizations. “The baby bats all adopted the manner of vocalizing of the group they heard, not their mothers. The difference between the vocalizations of the mother bat and those of the group is comparable to the difference in a London accent and, say, a Scottish accent,” Yovel said.

“The babies heard their mothers’ London dialect, but also heard the Scottish dialect produced by many dozens of Scottish bats. The babies eventually adopted a dialect that was more similar to the local Scottish dialect than to the London accent of their mothers.” Researchers hope to conduct future studies to examine how bats’ dialects change when they leave their social groups, and if it affects how they integrate with others.

1. What are the latest findings about bats?

A．Bats are born to adopt their mother’s dialect.

B．Bats can understand peers with different dialects.

C．Bats’ accents are influenced by their peer’s accents.

D．Bats pick up language quickly in company with their peers.

2. In paragraph 2, what does the underlined word they refer to?

A．Accents.	B．Baby bats.
C．Researchers.	D．Mother bats.

3. Why are London and Scottish accent mentioned?

A．To show the differences in dialects among social groups.

B．To explain why bat produce different sounds.

C．To indicate the birthplace of baby bats.

D．To compare how the two accents influenced understanding.

4. What will the future study most probably focus on?

A．How bats adopt a new dialect after entering a new social group.

B．What changes might occur to bats’ accent after entering a new social group.

C．Whether bats leave their social group if they change their accents.

D．Why some bats fail to be accepted in a new group after they are born.

10 . One of the easiest ways to stop the spread of disease is to simply wash your hands. Twenty seconds of handwashing with soap and water can reduce illnesses and save lives. But, many people, especially children, do not have good handwashing habits. One problem is that children do not wash their hands often enough or long enough. Children may think that it is a tiresome thing to do.

To help handle this problem, two businesswomen from India created a product to turn handwashing into a fun activity.   Amanat Anand and Shubham Issar created a tool called SoaPen, aimed at teaching kids good handwashing habits and encouraging kids to wash their hands with soap appropriately and regularly.

“It’s such a simple habit to do, but the fact is that people aren’t doing it, and it’s resulting in actual deaths---which is shocking. So, we decided to come up with a fun method, said Issar.

As the name suggests, SoaPen is a pen made out of soap. The children draw on their hands with the soap pen and then wash the drawing off. If they don’t spend enough time washing it off, the colors remain on the children’s hands. Issar said it makes sure that children take enough time to wash their hands. This may be especially helpful in a classroom. Often a teacher does not have the time to make each child wash his hands properly.

Kids actually wash their hands for the proper amount of time because they’re drawing on their hands. To obliterate the drawing, they actually wash their hands instead of just going under water and, you know, a one-second wash and off.

Good news is that the school children in Mumbai, India, will soon most likely wash their hands after handling a pet. Issar and Anand stated that SoaPen to be created everywhere will help promote good habits through handwashing in the city across the globe.

1. Why is SoaPen invented?

A．To teach kids the importance of handwashing.

B．To make money from children consumers.

C．To help kids wash their hands correctly.

D．To rid kids of some kinds of diseases.

2. Which statement will Issar probably agree with?

A．SoaPen is designed for classrooms.

B．Handwashing is anything but little.

C．Some teachers ignore kids’ health in school.

D．Kids don’t know the right way of handwashing.

3. What does “obliterate” underlined in paragraph 5 mean?

A．Remove.

B．Reserve.

C．Learn.

D．Show.

4. What can we learn from the last paragraph?

A．SoaPen has become popular worldwide.

B．Kids’ health should be paid more attention to.

C．SoaPen has been applied in Mumbai schools.

D．The inventors think SoaPen has a bright future.
