1 . Is there a place that you have a strong desire to visit before you are too old to travel? If so, you’re in my shoes. The following places are where I desire to visit very much and most probably your best choices.
Zhangjiajie National Forest Park
The region is famous for its amazing natural beauty. Many 5A scenic areas and geological(地质的)parks are located there. The park not only has natural wonders, such as strange looking peaks and a thick forest, but also rich animal and plant resources. Tourists can feel like stepping into a natural botanic(植物)garden and kingdom of animals. After visiting here, one will realize the great natural beauty of our world.
The Rainbow Mountains
These geographical(地理的)wonders look as if they were painted with a giant paintbrush. The bright colors stand obviously among the surrounding green plants. Wild as it is, these mountains are a part of our world in China’s Zhangye Danxia Landform Geological Park. This wild variety of color does exist in the real world. No Photoshop is necessary for the natural beauty of these mountains.
Bora bora.
This place offers the chance to live like a native Polynesian. The clear open sky and the calm waters offer you the unique opportunity to observe how the native people lead a life nearby the sea. Many holiday centers are built here and offer different tours and experiences.
The Galapagos Islands.
The islands consist of 13 volcanic(火山的)islands and six smaller islands. Although known for Darwin’s visit, they’re more attractive than you might imagine. There are 900 species of animals found on these islands. 200 of these species are specific(特有的)to the Galapagos. Most travelers come to this lovely place for the specific wildlife here.

2 . Tips for Green Travel with Kids
Traveling doesn’t mean letting go of all the eco-friendly choices we work so hard to achieve in our daily life. Here are a few tips for green travel with kids:
Booking nonstop flights whenever possible will reduce carbon emissions (碳排放). If the closest local airport doesn’t have nonstop flights to a certain place, check in with other local airports to see if nonstop flights are available.
Whether you’re flying or driving, it’s easy when traveling to pull into fast food restaurants for snacks.
Reusable water bottles are easy to bring along whenever you travel. At the airport, keep your reusable bottles empty until you have passed through the security (安检).
| A．Too much carbon emissions seriously pollute the environment. |
| B．But you can pack healthy food before starting off. |
| C．In this way, you can save water and energy. |
| D．Fill them up on the other side of the security checkpoint. |
| E．Security check is a necessary part of each trip. |
| F．Save energy by turning off the hotel room lights when you head out for the day. |
| G．You might have to drive a bit further, but saving on carbon emissions makes it worthwhile. |

Du Fu's early poetry celebrated the beauty of the natural world and bemoaned （惋惜）the passage of time. He soon began to write about war—as in “Bingche xing”・ And with hidden satire （讽刺）9 he wrote “Liren xing",
Du Fu's irreplaceable position in the history of Chinese literature
4 . At Englands University of Plymouth, Professor Eduardo Miranda has been programming pairs of robots to compose music. Miranda's robots have simple “ vocal cords”(声带)and are programmed to sing and to listen to each other. The robots' unique warbling sounds (颤音) do not perfectly match the human voice, but each machine is exactly sharing music with the other in a new and unique way.
Each robot is equipped with speakers, software that mimics the human voice, a mouth that opens as it “sings,” a microphone for ears, and a camera for eyes. The robots also move. Miranda hopes that by studying his robot vocalists, he can discover something about how and why humans create, perform, and listen to music.
When the robots sing, first one robot makes six random sounds. Its partner responds with more sounds. The first robot analyzes the sounds to see if their sequences (序列)) are similar. If they are, it nods its head and commits the sounds to memory, and the second robot notices and “memorizes” the musical sequence, too. If the first robot thinks the sounds are too different, it shakes its head and both robots ignore the sounds. Then the process continues.
Miranda set up an experiment in which he left the two robots alone in his study for two weeks. When he returned, his little warblers had, by imitating each other, not only shared notes but combined them. The product of their cooperation was far from symphonic, but the robots had begun to combine the notes into their own self-developed “songs”.
With the help of his warbling robots, one of Miranda's goals is to create music that no human would ever compose. Miranda believes the robots are ideal for this purpose because they would not be influenced by any existing musical styles or rules.

5 . Mice and rats have long been used in medical research because of their biological similarities to humans. Recently scientists at the University of Richmond in Virginia have trained rats to drive small vehicles.
The research team built tiny cars out of plastic and other materials, which had an opening at one end to which electrical wires were attached. By touching one of three different wires, the rat could control the car in different directions-left, center and right. Sweet treats were placed inside the containers in an attempt to get the rats to drive the vehicle for the food. After several months' training, the animals could drive to get to the treats.
Kelly Lambert, who has long been interested in the way the brain changes to react to different experiences and difficulties, led the experiment. She told the French news agency AFP the research suggested rat brains might be more complex and flexible than once thought. The driving activity seemed to help the rats relax and the rats kept in what was called “enriched environments” performed far better than those in labs.
The researchers examined levels of two hormones (荷尔蒙) in the rats — one that causes stress and the other that counters it. All the rats that took part in the training had higher levels of the hormone that reduces stress. The research suggests the increased relaxation levels could be linked to the enjoyment of successfully completing a new skill. The team also found the rats that drove themselves showed higher levels of the stress-fighting hormone than those that simply rode in small cars controlled by humans.
Lambert's team is planning to further the research to learn more about how the rats learned to drive. This research may open new areas of non-drug treatments for people suffering from mental health conditions.

6 . An unusual trip to Hawaii brought two strangers closer and closer and their story deserves a wide spread.
As her plane sliced through the sky above the ocean, there came a sudden thunderstorm. Five minutes later, Uemoto and her copilot McMahon heard a strange sound. Then, without warning, they lost power to both of the engines. It took them a moment to process the fact that they might crash. The pilots powered through the items on the emergency checklist. Nothing worked. As the plane was falling, they jumped into the ocean.
By ten that night, their bodies began trembling uncontrollably in the cool night air. Something must be done to pull them through. Swimming on her stomach, Uemoto had McMahon wrap his arms around her knees so he could rest his head on the back of her legs. To be with someone else and to feel another person's comforting presence in the darkness somehow made the suffering bearable.
When the sun rose the next morning, they caught sight of the island of Hawaii, the destination they had dared dream! Suddenly, Uemoto saw a shark, which made her breath catch in her throat. "What do we do? What do we do?" Uemoto asked, panicked. "Just keep looking forward! If it comes close, I'll kick it in the eye!" said McMahon evenly. Unexpectedly, the shark circled them for about 30 minutes. Then, as quietly as it had appeared, it swam off. Uemoto and McMahon breathed a sigh of relief.
After struggling in the water for over 20 hours, there came a US Navy helicopter. It flew overhead and next banked towards them. Uemoto and McMahon burst into tears. Alone, either of them would have died. But together, they made it.

7 . Student loan (贷款) debt has become a worldwide problem. In America, the country's overall student debt reached a record of $1.6 trillion in 2019. The average person with student loan debt owed between $20,000 and $25,000. A recent Japanese government report says it has been lending over $9 billion yearly to students since 2010. Similar conditions exist in Africa and South America.
Several factors account for high student loan debt. One is that employers everywhere have increased their demands for skilled workers, making higher education a requirement for many jobs. The students, however, after graduation, often find that their country's economy is not strong enough to support their financial needs, so their ability to pay back the loan becomes a problem.
To solve the problem, many countries are seeking their ways. Australia has developed a system where students do not have to pay anything back until they are earning at least $40,000 a year. In America, several candidates running for president in the 2020 election have offered more extreme solutions that all or at least some of these loans will be forgiven.
Some professors in several universities recently studied what the effects of debt forgiveness might be. They found that, overall, sudden debt relief greatly improved the borrowers' lives. Not only did they have more money, but they were more likely to move to a new area and seek better paying work.
Yet the professors' research doesn't include what might happen to financial institutions or the overall economy if debt were totally forgiven. It only looks at how debt forgiveness would help the borrowers. They warn of some other possible negative effects. If a borrower knew that if he ran into any trouble he would be saved because he could get the debt relief, then he might actually become more reckless (轻率的) with his borrowing in the future.
No matter what, the professors agree that if countries do decide to approve some student debt relief the neediest students should be helped first.

8 . There’s a man in the habit of hitting me on the head with an umbrella. At first I couldn’t stand it, now I’m used to it.
I don’t know his name. I know he’s average in appearance, wears a gray suit, and has a common face. I met him five years ago one hot morning when I was sitting on a tree-shaded bench in Palermo Park, reading the paper. Suddenly I felt something touch my head. It was the very same man who now, as I’m writing, keeps hitting me, mechanically (机械地) and impassively, with an umbrella.
On that occasion I turned around filled with anger. He just kept on hitting me. I asked him if he was crazy, he didn’t even seem to hear me. Then I threatened to call a policeman. Calmly, cool as a cucumber, he stuck with his task. After a few moments of hesitation, and seeing that he was not about to change his attitude, I stood up and hit him on the nose. The man fell down, but he immediately got back on his feet, obviously with great effort, and without a word again began hitting me on the head with the umbrella. His nose was bleeding and, at that moment, I felt sorry for him. I felt regret for having hit him so hard. After all, the man wasn’t exactly hitting me; he was merely tapping me lightly with his umbrella, not causing any pain at all. Of course, those taps were extremely bothersome. As we all know, when a fly lands on your forehead, you don’t feel any pain; what you feel is annoyance. Well then, that umbrella was one huge fly that kept landing on my head time after time.
Convinced that I was dealing with a madman, I tried to escape. But the man followed me, wordlessly continuing to hit me. So I began to run (I should point out that not many people run as fast as I do). He took off after me, trying to land a blow. The man was out of breath so that I thought, if I continued to force him to run at that speed, he would drop dead right then and there.

9 . As Internet users become more dependent on the Internet to store information, are people remember less? If you know your computer will save information, why store it in your own personal memory, your brain? Experts are wondering if the Internet is changing what we remember and how.
In a recent study, Professor Betsy Sparrow conducted some experiments. She and her research team wanted to know the Internet is changing memory. In the first experiment, they gave people 40 unimportant facts to type into a computer. The first group of people understood that the computer would save the information. The second group understood that the computer would not save it. Later, the second group remembered the information better. People in the first group knew they could find the information again, so they did not try to remember it.
In another experiment, the researchers gave people facts to remember, and told them where to find the information on the Internet. The information was in a specific computer folder (文件夹). Surprisingly, people later remember the folder location (位置) better than the facts. When people use the Internet, they do not remember the information. Rather, they remember how to find it. This is called “transactive memory (交互记忆)”
According to Sparrow, we are not becoming people with poor memories as a result of the Internet. Instead, computer users are developing stronger transactive memories; that is, people are learning how to organize huge quantities of information so that they are able to access it at a later date. This doesn’t mean we are becoming either more or less intelligent, but there is no doubt that the way we use memory is changing.
