1 . The word "orange" describes both a color and a fruit. Which one came first might be surprising. "Orange" when used as the name of the fruit came before "orange" as a word to describe color. While the shade itself existed before the fruit, there was not a name in the English language for the color. Before the introduction of the fruit to English-speaking countries, the color was usually described as a shade of red or yellow.
In the early 16th century, Portuguese traders brought oranges from India to Europe. The Europeans had not seen the bright colored fruit before and didn't have a name for it. The fruits were named "narancia" by Italians and "narange" by the French and were sometimes referred to as "golden apples" by English speakers.
"Orange" was first used in a phrase to describe shades of colors, including in a third-century Greek text translated into English, in 1576. It describes Alexander the Great's servants as dressed in "orange colour velvet （天鹅绒）In 1578, a Latin-American dictionary defined "melites" as "a precious stone of orange color”. While orange represents the color of the objects, it needed the word "color" to follow it in order for the meaning to be clear. In the mid-1590s, Shakespeare described a beard as "orange tawny", one of the first instances of "orange" without the word "color" as part of the expression. Tawny is a brown color often used on its own. Orange was not yet a color, just a shade of brown.
In 1616, in an account describing varieties of tulips （郁金香）that can be grown, orange was used as a stand-alone color. When Isaac Newton performed his experiments on the color spectrum （色谱），he listed it as one of the seven basic colors. After almost half a century, orange was recognized as a color on its own.

2 . One day in March,seven years ago,during happy hour at a bar in my hometown of Fayetteville,Arkansas,made a surprise announcement to my friends:I was going to shut down my law practice and attempt to travel around the globe in a year.What’s more,I would do it without taking any flights or making a single advance reservation of any kind.My announcement drew mixed reactions from my friends.Some offered support and encouragement,while others were more doubtful.
Once I had said the words,there was no turning back.It took months to shut down my practice and get things in order.Once I set off on my adventure in December 2008,found travelling without using planes was not easy.Trying to circle the globe in 16 months(it took me a bit longer than the initial 12 months planned)made it even harder.Even so,travelling overland was the most amazing way to truly understand the immensity(浩瀚无际)of our wonderful planet.
I took three consecutive(连续)overnight buses to travel 3,000 km through Argentina,from Ushuaia to the capital Buenos Aires.I would look out the windows for hours on end of the completely unspoiled plains,as if humans had never touched it.
It took seven consecutive days and nights on trains to get from Moscow to Beijing,each day spent staring out the windows for hours as the Siberian plains swept by.Sometimes,I wouldn’t see a village or a human being for 10 hours.Later in my journey,it took 22 days on a cargo freighter(货船)to get from New Zealand through the Panama Canal and back to Philadelphia,to finish my round-the-world adventure.
It turned out that travelling with no reservations was far less difficult than had imagined.Pulling into a city on a bus with a backpack,looking in a guidebook for a few suggestions of accommodations(住宿),and then finding an empty room was never much of a problem anywhere.It also kept me flexible and open about all my travel plans,which is advice I give everyone who asks—plan far less than you think you should.

3 . One night in March, five years ago, during happy hour at a bar in my hometown, I made a surprise announcement to my friends: I was going to shut down my law practice and attempt to travel around the globe in a year. What’s more, I would do it without taking any flights or making a single advance reservation of any kind. My announcement drew mixed reactions from my friends. Some offered support and encouragement, while others were more doubtful.
Once I’d said the words, there was no turning back. It took months to shut down my law practice and get things in order. Once I set off on my adventure in October 2016, I found that travelling without using planes was not easy. Trying to circle the globe in 16 months (it took me a bit longer than the initial 12 months I planned) made it even tougher. Even so, travelling overland was the most awe-inspiring way to truly understand the immensity of our wonderful planet.
I took three consecutive overnight buses to travel 3,000 km through Argentina, from Ushuaia, the world’s southernmost city, to the capital Buenos Aires. I would look out the windows for hours on end at the completely unspoiled plains, as if humans had never touched it.
It took seven consecutive days and nights on trains to get from Moscow to Beijing, each day spent gazing out the windows for hours as the West Siberian Plain swept by. Sometimes, I wouldn’t see a village or a human being for 10 hours. Later in my journey, it took 22 days on a cargo freighter to get from New Zealand through the Panama Canal and back to Philadelphia, to finish my round-the-world adventure.
It turned out that travelling with no reservations was far less difficult than I had imagined. Pulling into a city on a bus with a backpack, looking in a guidebook for a few suggestions of accommodations, and then finding an empty room was never much of a problem anywhere.

4 . There has been a lot of publicity (宣传) recently surrounding 5G, the next generation of wireless technology for the world. But what is this technology and how might it change our lives?
What is 5G?
5G stands for fifth generation, meaning the next step in the progression of technology to replace the current 4G system. 4G was the replacement for 3G, which came after 2G, and so on. These systems are wireless computer networks. Earlier “G” systems were designed to improve mobile communication operations. Each new technology brought major improvements in speed and greatly increased network capacity. The new 5G system promises more of the same. It is expected to permit more users to do more things-at a faster rate. Higher internet speeds and larger network capacity should result in better performance for device users connected to 5G. However, technology experts say there is a major way that 5G is different than the earlier systems. It will move well beyond mobile network technology to affect many more devices and industries than other “G” versions.
When will it be available?
Before we can all use 5G, wireless companies and phone makers will have to complete and deploy (部署) a whole new system. New phones and communication equipment must be built. American wireless companies have been preparing for the new system for some time. They have been creating new network equipment and buying broadcasting space to carry 5G signals. They have built news G antennas(天线)to serve American cities and towns. Wireless providers will invest at least $275 billion n 5G-related networks in the United States, the industry group CTIA reported. The first U.S, launch of 5G is expected to happen sometime this year. Industry experts expect it will take a few more year to go nationwide. It will take even longer to reach rural areas. China is expected to launch 5G sometime in 2020, while European nations are likely to build their systems more slowly over time.
1. Which system is widely used nowadays?| A．5G. | B．2G. | C．3G | D．4G. |
| A．It will allow more users to do more things. | B．The internet speed will be much higher. |
| C．The users will spend much less money on it. | D．It will affect more devices and industries |
| A．5G system has nothing to do with phone makers. |
| B．There is much work to do before 5G comes into use. |
| C．New phones will be much smarter than those used now. |
| D．4G system will be stopped as soon as 5G comes into use. |
| A．USA→China→European nations. | B．China→USA→European nations. |
| C．USA→European nations→China. | D．European nations→China→USA. |
5 . A team of researchers at Brigham and Women’s Hospital, Harvard Medical School, has developed a system to use a smartphone camera to test for viral infections. In their paper published in the journal Science Advances, the group describes their system, which involves the use of an external microchip device and a smartphone system that uses a trained deep-learning algorithm.
As the pandemic has gripped the world for most of this year, scientists have been looking for ways to slow the spread of the next one. In this new effort, the team has developed a smartphone-based system that can be used by non-medical people to test for a variety of viral infections.
The system is made up of a smartphone, an external microchip device and software. Body fluid samples are placed into a channel on the microchip device, which is then dipped in a small amount of H2O2. The resulting reaction leads to the formation of bubbles. The bubbles develop in unique patterns based in part on viruses in the fluid sample. The user points their smartphone camera at the bubbling sample and starts the deep-learning algorithm that has already been trained to identify the patterns and therefore recognize the presence of viruses. The whole process takes about 50 minutes. The researchers have thus far taught their system to recognize just three viruses, Zika and Hepatitis B and C. But testing shows the system to be 99% accurate. They note that their system is more portable and cost-effective than other solutions in the works.
The researchers suggest that their system could be rapidly trained to recognize new viruses if the need arises, and the microchip device could be sent to hot spots in the future. Such technology, the researchers suggest, could help to stop future pandemics if used widely. The researchers also note that the system could be immediately useful in infection prone areas lacking testing labs.

6 . In work, as well as in life, doing what needs to be done in order to reach our goals can be difficult. Without a good system in place, it is easy to lose focus, waste time and lose track of our most important tasks. Luckily, one of the most efficient(高效的)useful ways is also one of the world's easiest---the Pomodoro Technique.
The Pomodoro Technique was developed by Francesco Cirillo in the late 1980s, which breaks down your work into 25-minute blocks(一段时间)divided by short breaks. Cirillo named the system after the tomato-shaped kitchen timer(计时器)that he used to track his work time when he was studying in university, where he developed a habit of doing short blocks of work followed by resting periods. He realized this method could help him work with time instead of struggling against it. In 2006, Cirillo published his Pomodoro Technique manual for people to download free of charge. It was downloaded over two million times.
The Pomodoro Technique was built around a handful of important steps. First, choose a task that you'd like to get done. It can be something big, something small, or something that you've been putting off for months. What matters is that you are ready to give it your full attention.
Next, set a timer for 25 minutes. Try to spend the full 25 minutes with your complete attention on the task. Then, when the timer goes off, take a five-minute break. Sit back, have a drink, go for a short walk, or do something else that doesn't relate to work. Treat yourself to a longer break that lasts 15 to 30 minutes after you have completed four of these 30-minute cycles. In theory, the longer break will allow your brain to relax, reset, ready for the next round of Pomodoros.
After trying the Pomodoro Technique, you may want to experiment a little. Some people have found that 90-minute blocks work best, while others might perform better with more flexible periods. It varies from person to person. Just remember, like many things in life, simpler is often better!

7 . Yellowstone National Park became America’s first national park in 1872.The National Park Service was formed 44 years later. Yellowstone, which is mostly in the state of Wyoming, is considered as a great example of the National Park System. Humans have been present in Yellowstone for more than 11,000 years.
The first organized exploration of the area which lies close to the Continental Divide of North America took place in 1870.Those first organized explorers must have seen right away how special the land was. Yellowstone contains beautiful mountains, deep canyons, lakes and rivers.
The name Yellowstone comes from the river running through the area. At first known as Rock Yellow River, later it became known as the Yellowstone River. Yellowstone is home to many different species of plants. However, the park is most special because of what lies underneath it. It sits on top of an ancient super volcano. And it remains an active volcano. It is believed that the last time the volcano erupted was a half million years ago. The area has had three major eruptions in the last three million years. Experts say it may erupt again in another 1,000 to 10,000 years. But each year, there are thousands of earthquakes at Yellowstone. Most are too small to be felt by people visiting the park.
Yellowstone is filled with the beauty of many hot water springs. Of all the geothermal(地热的)places in the world, half are in Yellowstone. In places of geothermal activity, hot water and gases are trapped under the earth’s crust. In places like Yellowstone, they rush to the surface in the form of hot water and steam to form geysers(喷泉).There are more geysers and hot springs in Yellowstone than anywhere else on Earth. The most famous geyser is Old Faithful. It erupts about every hour or hour and a half. The eruption can last from one and a half minutes up to 5 minutes. The amount of hot water it pours in that time can be as much as 31,000 liters or more.

Savor wild Alaskan salmon grilled over an open alder wood fire, a variety of salads, cornbread and dessert. After your meal, you may return or be dropped off in Skagway for shopping. Guest Reviews (4) Palp from Vancouver ★★★☆☆ Great one hour stop at the Suspension Bridge. The salmon bake in Liarsville was the best part! It was a buffet of UNLIMITED salmon that was being freshly cooked over an open fire. Overall good excursion, just a little too expensive for what it is. Dragon from Los Angles ★★★★☆ Did this on May 1, 2019. Our guide, Glenn, was very enthusiastic and knowledgeable, keeping us entertained all the way by making jokes and explaining the history of the landmarks. There were only 12 people, so we all had window seats!! The views were GREAT! Took lots of pics. Plutocrat from Edmonton ★★★★★ Enjoyed the drive, enjoyed the fees and enjoyed Liarsville, where the food was AMAZING. Can't believe how much we enjoyed walking across the suspension bridge. Rod from Regina★★☆☆☆ “To the Summit” gives the impression you are going to the big summit. This was not the case. The summit in question was just a small hill. The views at the suspension bridge are ok but not incredible. The lunch at Liarsville was not bad, though, and that stop was best of the day. |

10 . The story of chocolate begins with the discovery of America in 1492. Columbus was the first European to come into contact with cacao. Columbus was struck by how much value the Indians placed on them as he did not know the beans were used by currency. It is unlikely that Columbus brought any of these beans back to Spain and it was not until about 25 years later that Cortez grasped the commercial possibilities when he found the Aztecs using the beans to make the royal drink “chocolate”.
The Spanish, in general, were not fond of the bitter drink so Cortez and his followers made it more palatable by adding cane sugar and later cinnamon and vanilla were added. Spanish monks let the secret out back home and, although the Spanish hid it from their neighbors for a hundred years, finally chocolate’s popularity grew until it was their fashionable drink at the French court and the wise choice of customers at London meeting houses.
The cacao tree is strictly a tropical plant only in hot, rainy climates. Thus, its cultivation is limited to countries not more than 20 degrees north or south of the equator (赤道). The cacao tree is very delicate and sensitive. It needs protection from the wind and requires a fair amount of shade under most conditions. This is true especially in its first two or three years of growth. A newly planted young cacao tree is often sheltered by a different type of trees. It is normal to plant food crops for shade such as bananas, plantain, coconuts or cocoyams. Rubber trees and forest trees are also used for shade. Once established, however, cacao trees can grow in full sunlight, provided there are fertile soil conditions and intensive farming. With cutting and careful cultivation, the trees of strains will begin bearing fruit in the fifth year. With extreme care, some strains can be stimulated to produce good crops in the third and fourth year.
The process of turning cacao into chocolate hasn’t changed much since the Swiss made the major breakthroughs in the process in the late 1800s. First the beans go through a process of fermentation ( 发酵 ) and drying. They are then sorted by hand before cleaning and then roasting. Winnowing ( 风 扬 ) follows which removes the hard outer layers and leaves what is as the “grains”. A crushing and heating process known as Hunte’s Process is then used to remove nearly half of the cocoa butter from the nibs. This makes unsweetened chocolate. Basic eating chocolate is made from a mixture of the unsweetened chocolate with some of the cocoa butter along with other ingredients such as sugar and vanilla. The resulting product is then “purified” and this purifying gives chocolate the silky texture that we know so well. The finished result is then shaped, cooled, packaged by machine, distributed, sold and of course, eaten!
