1 . Some Ohio high school students have become winners in a national contest (竞赛) after inventing a mobile phone app that helps needy families find local food pantries (公益食品仓库).

And someday the teens, who are students at Ross High School in Ross Township, may be selling the app to food pantries and food banks across America.

The app was created as part of a computer science class — coordinated (协调) by Butler Tech career school system at the high school. Three students, Jacob Kahmann, Gunner Nonnamaker and Kyle Inderhees, recently were visited by Congressman Warren Davidson, who praised their work. Davidson lauded the teens for creating “this app to set the standard for efficient food collection and distribution (分发)”.

Butler Tech IT Instructor Tom O’Neill said the students’ app includes characteristics that help users locate the nearest food pantry and improve food collection processes, and that the national contest provides a real-life learning chance for his students.

The students are continuing to make additions to the app and are working on turning it into a product, said O’Neill, who in recent years has helped many Ross High School teens win national honors for their computer-science-based inventions.

“The teachers and students in the Ross School District continue to amaze me with their future-thinking and creation,” said Superintendent Scott Gates. “Our students are not only thinking about careers, they are thinking about problems they want to change, solve or improve. The app that was created will make serving a population in need more efficient.”

2 . Cultures have nonverbal forms of communication, but there are still rules. Hand gestures add emphasis. Voice levels add to our communication.     1    

Body language is not the same everywhere. The same body postures and gestures can have different meanings in different cultures. For example, holding your hand out, fingers together, and palm (手掌) facing outward means stop in North America.     2    

Ojigi, or Japanese bowing, is used as a way to say hello, a way to say sorry, and a way to show respect.     3     Fifteen degrees is the common greeting bow for those you already know or who are on an equal social level. The highest respect bow is forty-five degrees and is used when you say sorry.

Other forms of nonverbal communication include clothing, hairstyles, and even how close we stand to one another. Proxemics is the study of the cultural use of space.     4     The use of color in one's physical space is an example of proxemics of physical territory. A health spa (休闲健身中心) is more likely to use cool greens and blues to create a relaxing environment.     5     This differs depending on the other person and the situation. For example, in the United States public space is between twelve to twenty-five feet. Intimate (亲密的) space is less than a foot. We may feel uncomfortable if any of these distances are reduced without an invitation.

A．In Greece, the same gesture is highly rude.

B．Personal space is between two and four feet.

C．Even silence can be a useful form of communication.

D．The degree of the bow shows the amount of respect.

E．This can be both someone’s personal and physical territory.

F．It is not impolite to look the other person in the eye while bowing in Europe.

G．Personal territory refers to the space we keep between others and ourselves.

3 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

The robot lawn mowers (割草机)     1     (design) by us have the following benefits besides saving you time and effort.

First, they are environmentally friendly. With global warming now     2    (be) a major concern you can have peace of mind with these mowers. They run on rechargeable batteries and do not use petrol or burn oil like conventional lawn mowers.

Second, they work very     3     (quiet). After careful assessment, noise from them     4     (find) to be about 60 decibels (分贝) lower than a typical lawn mower, so you can program them to work at night while you sleep.

Third, rain sensors in our robot lawn mowers warn the robot     5     (return) to its shelter or stay in its shelter while it’s raining. On     6     other hand, if you are using a simple electric lawn mower, you will have to stay out in the rain while you get your mower under shelter     7     it will be useless.

Fourth, bump sensors in our robot lawn mower protect the lawn mower from running over items     8     may be lying in the yard, thus increasing its life and efficiency.

Last but not least, they are    9     (benefit) for people with allergy problems — they can cut your grass while you sit far away, reading your favourite novel     10     comfort.

4 . Yellowstone National Park, located in Idaho, Montana, and Wyoming, was established as the first national park in the United States. The park is a popular destination for visitors who enjoy ecological (生态的) tourism as it offers forests, mountains, and many ecosystems to explore. Some of Yellowstone’s most well­known landmarks are its geothermal (地热的) hot springs and geysers (间歇泉), the most famous of which is named Old Faithful.

Last fall, Lisa and her friends decided to take a camping trip to Yellowstone National Park. They arranged to stay at one of the park’s many convenient campsites. For their camping trip，they brought their backpacks, sleeping bags, and a cooler of food and drinks. They set up their tents immediately upon arriving at their campsite.

During their trip, Lisa and her friends hiked the many trails (小道) of the park, exploring its natural surroundings. In the forest, they saw a lot of local wildlife. Lisa was blown away by a family of grizzly bears, some gray wolves, and even bald eagles flying overhead. Unexpectedly, she seemed to quite enjoy being in such a great place. They were well protected. Outside of the woods, they admired the beauty of some of Yellowstone’s natural waterfalls.

Since Yellowstone contains many hot springs and the world’s largest area of active geysers, Lisa and her friends visited many different geyser sites.They even spent an afternoon swimming in Yellowstone’s Boiling River. Of all of the sites, Lisa and her friends agreed that Old Faithful was the most impressive. Lisa and her friends waited patiently for the geyser to erupt. After about 40 minutes, a stream of boiling water over 100 feet tall sprayed (喷洒) from the ground and up into the air. Luckily, no one got wet!

5 . Tourists visiting La Gomera and EI Hierro in the Canary-Islands can often hear locals communicating over long distances by whistling-not a tune, but the Spanish language. The locals are communicating in Silbo, a whistled Spanish language.

Whistled languages are almost developed in rough, mountainous regions or in thick forest. That’s because whistled speech carries much farther than ordinary speech or shouting. As a result, whistled speech can be understood up to 10 times as far away as ordinary shouting. That lets people communicate even when they cannot easily approach close enough to shout. On La Gomera, for example, a few traditional shepherds (牧羊人) still whistle to one another across mountain valleys that could take hours to cross.

Whistled languages work because many of the key elements of speech can be produced in a whistle, says Meyer. We distinguish(区分) one speech sound from another by small differences in their sound frequency patterns. A long e, for example, is formed higher in the mouth than along o, giving it a higher sound.

To language scientists, such languages are more than just a curiosity. By studying whistled languages, they hope to learn more about how our brains get meaning from the complex sound patterns of speech. Whistling may even provide a chance to know one of the most dramatic jump forward in human evolution(进化): the origin of language itself.

Despite their interest to both language experts and casual observers, whistled languages are disappearing rapidly all over the world, and some, such as the whistled form of the Tepehua language in Mexico, have already disappeared. “...now you still find whistled speech only in places that are very, very remote, that have had less contact with modernity and less access to roads,” Meyer says.

Fortunately, there is still hope. UNESCO, the UN cultural organization, has listed two whistled languages, Silbo, and a whistled Turkish, as the world’s cultural heritage. Such attention can lead to conservation efforts.

1. What led to the development of whistled languages?

A．Geographic inaccessibility.	B．Rapid increase in tourism.
C．Greater information capacity.	D．Interest of language experts.

2. Why are a long “e” and a long “o” mentioned in paragraph 3?

A．To show what key elements speech has.

B．To explain the differences between speech sound frequency patterns.

C．To prove the popularity of whistled language in the world.

D．To compare whistled languages and ordinary languages.

3. What might be a reason for the disappearance of whistled languages according to Meyer?

A．Construction of cities.	B．Lack of attention.
C．Expansion of other cultures.	D．Modernization.

4. Which of the following could be the best title for the text?

A．Why People Used Whistled Languages	B．When Whistles Languages Disappeared
C．How Whistled Languages Developed	D．Why Whistled Languages Matter

7 . Travelling Economically

● Get a ride to travel destinations with friends or acquaintances (熟人). If people you know are driving to a location you would like to visit, take advantage of the opportunity to ask them for a lift. Offer to help with gas money or, if you don’t have any cash, offer a trade or service instead.     1    

● Practice safe hitchhiking to get around.    2     Ask each driver several questions before getting in the vehicle, including what their name is, where they are heading and why they are going there. Follow your gut instinct (直觉) and avoid getting into a car with anyone who gives you a bad feeling.

●    3    There are many ridesharing websites and apps that allow budget travellers to find a shared lift to their destination. These sites will also screen and identify the drivers, making the ridesharing experience safe and simple. Search for available rideshares in your area, which may vary in cost but will cost significantly less than travelling alone.

● Join a free hospitality (好客)-sharing community.     4    You will be able to chat with participating members living in the area you are travelling to and arrange accommodations before travelling. In addition to being able to sleep on someone’s couch or in their spare room, you may find someone to show you around the city.

● Camp at inexpensive campsites. Camping can be a budget-friendly activity if you find the right park or site.     5    Visit http://www.uscampgrounds.info/ for a comprehensive list of North American campgrounds, which indicates sites with a rate of $12 or less per night.

8 . As the lyrics to Taylor Swift’s hit song “Bad Blood” go: “Cause, baby, now we got bad blood. You know it used to be mad love.” It’s a song about falling out of friendship, but to 14-year-old Hallie Barnard, who was born with a rare blood disorder, the song holds a much deeper meaning.

At just 15 months old, Barnard was diagnosed (诊断) with Diamon Blackfin Anemia, or DBA, and she spent most of her life in and out of the hospital. The Swiftie said she relied on the singer to bring her joy.

The only way to survive DBA is with a bone marrow transplant (骨髓移植) and Barnard was desperate for one. But she knew thousands of other patients are, too. So, a few years ago, she decided to do something about it, creating her own foundation: Hallie’s Heroes. “It started selfishly as just trying to save my life, but then we realized there were so many other children out there that needed a bone marrow transplant,” she said. “So, so far we’ve tested 8,000 people and found over 300 matches.”

After a 9-year wait, Barnard got her own match — through her own foundation. But more obstacles stood between her and normal life as a kid. The blood disorder led to a cancer diagnosis: osteosarcoma. She received surgery to cut the cancer out of her leg at MD Anderson in Houston.

The recovery was difficult, but Hallie said she stayed hopeful. “My survival instinct (本能) just kicked in. I was trying to do anything that I could to survive. So, of course, it was scary but in my mind, I was just thinking that I wanted to be at my sister’s future weddings. I wanted to play games and run again,” she said.

Her survival instinct —combined with Taylor Swift―helped her through her operation, where doctors cut her cancer out, and reattached her foot and ankle to her upper leg to work as a knee.

9 . Tea originated in China over two thousand years ago. Today, the country owns over 2,000 varieties of tea, differing in taste, sweet and purpose. Some teas, such as Huang Shan, refresh the sense of taste with their special flavor, while others, such as spicy chai, are added with spices (香料) .

China first started exporting tea during the Ming dynasty (1368—1644), and the drink has since come to lead humanity’s drinking habits far beyond Asia. It is the most widely consumed drink on Earth today, aside from water and coffee.

In Chinese mythology, tea was first discovered by Chinese Emperor Shennong (“Divine Farmer”) in 737BC， when a soft wind carried some leaves into a pot of boiling water. However, the oldest dependable evidence comes from ancient plant remains found in 2016 in Xi’an and western Tibet, showing that tea was grown at least 2,100 years ago during the Western Handy nasty when it was most likely used as medicine.

Generation after generation of tea makers experimented with different brewing (冲泡) techniques, leaves, and ceremonies, resulting in today’s tea culture full of life. There’s no doubt that China’s tea culture has become one of the most popular, diverse, and unique traditions in the world.

China is already the world’s largest tea exporter. The inclusion of the country’s traditional tea-making process on the UNESCO list will obviously generate practical benefits for tea makers in the country and across the world as more resources are given to protect and preserve such millennia-old tea culture and technical practices. As additional attention is brought to this traditional technique, the Chinese tea sector will further tap its potential and improve its growth.

As one of China’s oldest cultural practices, traditional tea processing techniques show the spirit of modesty (谦逊), peace, and comity (礼让). No matter your preference for green or dark tea, with milk or without, Chinese tea isn’t just brews. Instead, it is a bridge connecting different cultures and peoples.
