1 . Banff National Park is home to an amazing wildlife population. But the busy Trans Canada Highway that cuts through the park is a hazard to the lovely animals. To address the problem, Banff first put-up wildlife fencing on either side of the highway to discourage animals from entering the busy road. Then, since 1996, they’ve opened six wildlife overpasses and 38 underpasses to help the animals cross the highway in safety. I was fortunate to visit Banff’s Red Earth Overpass with Trevor Kinley, the project manager with Parks Canada. He told me that so far, they have documented 10, 000 safe animal crossings on this overpass alone. “ Some animals have learned how to use the crossings much more quickly than others. Black bears are the fastest learners, followed by deer. Wolves and lions take the longest to work out how to use them, ” Kinley said, laughing. “ But those animals that are slower to adapt are usually more capable and determined at figuring out the safest way to cross those overpasses and underpasses. ”

There is some criticism (批评) that channeling so much wildlife into a few bridges and tunnels is like making a trap for the animals, offering big animals an easy meal on either side. “ But research has shown that this is not the case, ” Kinley assured me. “ There are no more killings around the crossings than there are anywhere else in the park. ”

Walking over the Trans Canada and then walking underneath through one of the tunnels, I was amazed to see the fresh tracks of black bears, wolves, deer and many kinds of smaller animals. Somehow, all these animal footprints made me so happy, knowing that all this wildlife was passing safely under and over the longest road in Canada.

Hopefully, the success of the wildlife crossings in Banff will continue to inspire similar solutions around the world, where human pressure on wildlife continues to grow.

5 . A professor was teaching his class. All the students were listening to his _______ with great interest. But there was one student whose_______ of mind showed he was in a bad mood.

The professor took notice of this student on the first day but did not say anything. But when this _______ for a week, he asked. “You are _______ in spirits all the time. What is the matter? Have some trouble?”

“Sir, that...” the student said. “... something has happened in my past, _______ which I remain troubled. I don’t know what to do.”

The professor was a(n) _______ good person. He called the student at his house in the evening.

When the student _______ the professor’s house, he was greeted with a _______ welcome. The professor went to the kitchen and started making lemonade for his student. He _______put more salt in the lemonade.

__________ the student had a taste of it, his mouth became sour. __________ this, the professor asked, “Did you not like the lemonade?”

“No, sir, this is not the __________. Just a little more salt in the drink,” the student said. “Now it’s useless. I will throw it away.” The professor __________ his hand to get the glass of drink from the student. But the student refused, saying, “No, sir. If you add more__________, the taste will be fine.”

Upon hearing this, the professor became serious and said, “You are right. That’s what I want to__________. Just as salt cannot be taken out of the lemonade, those bad experiences also cannot __________ life. Adding more sugar can change the taste of lemonade. In a(n) __________way, sweetness has to be dissolved (溶解) in life to forget bad experiences. I want you to take the sweetness in your life into __________ now.”

To his relief, the student __________ him and decided from then on he would not be troubled by the __________.

6 . Japanese researchers placed electronic devices(装置)on seals(海豹)in Antarctic waters to collect surprising information about the environment there. Japan’s National Institute of Polar Research started the research project in 2017. The team recently reported its results in a study in the publication Limnology and Oceanography.

Eight Weddell seals were fitted with the devices,which have antennas(天线)to send electronic signals.The 580-gram monitoring devices were attached(缚上;系上)to the animals’heads. They were designed to measure data such as water temperatures and sea salt levels.

Investigative teams on ships have difficulty reaching important research areas in Antarctica. These include areas along continental shelf formations where ice is attached to the shore, the National Institute of Polar Research said in a statement. Nobuo Kokubun led the project. Since the seals are active year-round, Kokubun added, “I thought we should have them collect the data.”

He told Reuters that the research also helps scientists follow the seals’ behaviors and learn about their relationship to the environment. “During the summer, we can go to Antarctica on icebreakers to conduct actual research activities, so that we can collect data there.” Kokubun said. ”But during the winter. such things cannot be done in so many places.“

Information gathered from the seals showed that one of the animals traveled as far as 633kilometers from Japan’s Showa Station in Antarctica. Another dove to a depth of 700 meters.Kokubun said the scientists learned from the data that warm seawater from the upper levels of the open sea reached Antarctica from March through the winter of 2017. The water flowed below the ice, bringing in sea creatures like Antarctic krill, an important food for seals.

Kokubun and his team plan to keep finding new ways to further examine the effects of climate change on Antarctic coastal areas. Next, he hopes to make the device small enough to fit on other animals at the South Pole, such as penguins,“The advantage with penguins is that they come back to the same place and we can collect data from them immediately,”Kokubun said.

7 . Chen Yuzhu, a 29-year-old young man, opened his first Chinese beef rice noodles restaurant in 2014 in the neighborhood of New York City’s Queens borough. He then took the flavor of his childhood memory to three other states in the US, building a recognized brand.

Actually, he started his own catering (餐饮) business after he lost his job and found noway out. It was at that time that beef rice noodles of his home village flashed in his mind.

However, the early days of setting up his business were not that easy. He frequently worked 18 hours a day, transported food at 2 am and promoted (推销) the restaurant near the New York City subway entrance by yelling, “Special noodles from my hometown, Guizhou!” But it didn’t work well. During the first two weeks. daily sales were only $200 at most, which wasn’t enough to pay the rent. He felt so anxious that he tried every possible means. Two months later, his Chinese beef rice noodles finally gained great popularity. His store has become hot spots for vloggers (视频博主) and he has made himself famous among locals as the“Rice Noodle Prince”.

“At first, running restaurants was for survival, but then I felt a sense of achievements. I became more open, inclusive and made a lot of friends. And the process to learn, make efforts and get inspired was really cool.” Chen said.
