    Once the home to African elephant specimens and surprising casts of a Triceratops and Diplodocus, the museum's main hall now floats the real skeleton of a blue whale high above visitors' heads. Though no longer in the entry hall, you can still find dinosaurs here, such as the first fossil ever found from a T. rex.

    This happened several years ago when I was still quite new in the city. I was doing my grocery shopping one day, and when I wanted to pay for my things, it turned out that I didn't have enough funds on my bank account for the things I'd chosen. It seemed something had been paid from my account that I had forgotten about.

    I was so embarrassed and ashamed. There was a queue forming behind me. I became very flustered (慌乱的) and very close to tears. I tried to quickly pick some things out that weren't so urgent for me to buy. The cashier (收银员) , a patient, elderly man, saw how upset I was and gently said, "Please, don't worry about picking out groceries to leave behind and you can pay me back for the difference another day." I immediately refused since I didn't know him, but he insisted he would pay for the difference because he also had daughters and sometimes life could be hard. I thanked him greatly while I packed my things. I asked him what his name was so I could bring the money another day. He said, "Just ask for Baba (Father) and everyone calls me that here."

    I came back a few days later with the money, a thank-you card, and some homemade cookies. I asked a young salesman if he'd seen the old man and he immediately told me, "Oh! That must be Baba!" It was clear that he was very familiar with him. I explained what had happened and he nodded. "Yes, that is something he would do. He is a bit of an extra father to all of us working here, too. He isn't working today but I will make sure he gets this."

    Thank you, Baba, for looking out for me that day, and for taking good care of your coworkers, too! I think it is people like Baba that make the world beautiful.

    How many afternoons have you slowly moved over to the office coffee machine and wondered: Is this really my fourth cup of the day? Or wait, is it my fifth? We've all been there, but a new study shows refilling your cup too often could be hurting your health.

    The study, published in The American Journal of Clinical Nutrition suggests that drinking six or more cups of coffee per day may increase your risk of heart disease by up to 22%. Researchers from the University of South Australia also found a specific gene, called CYP1A2, which enables people to consume caffeine faster than those without it.

    Overall, the researchers found that people who drank six or more cups of coffee a day were 22% more likely to develop cardiovascular (心血管的) disease, compared to those who drank one to two cups daily. The study authors believe that coffee (in large quantities) and heart problems may be linked because excess caffeine consumption can cause high blood pressure, a risk factor for cardiovascular disease.

    Most people would agree that if you drink a lot of coffee, you might feel nervous and irritable (易怒的) .That's because caffeine helps your body work faster and harder, but it is also likely to suggest that you may have reached your limit for the time being. That doesn't mean that any and all coffee is bad for your heart, however. In fact, the researchers also found that participants who didn't drink coffee at all — and those who drank decaf — also had higher rates of heart disease (11% and 7% higher, respectively) than those who drank one to two cups per day. Previous research has found coffee is rich in antioxidants (抗氧化物质) and may reduce the risk of heart disease, stroke, and diabetes.

An increase of just 2℃ in global temperatures could make the world considerably drier and more desert-like, new research has warned.

    More than a quarter of the world's land surface, home to more than 1.5 billion people, would become more arid and droughts and wildfires could be widespread. Limiting global warming to 1.5℃ would dramatically reduce the percentage of the Earth's surface affected, scientists found.

    "Aridification (干旱化) would emerge over 20 to 30 percent of the world's land surface by the time the global temperature change reaches 2℃"，said Dr Manoj Joshi from the University of East Anglia's School of Environmental Sciences and one of the study's co-authors.

    The research team studied projections from 27 global climate models and identified areas of the world where aridity will greatly change. The most affected areas are parts of South East Asia, Southern Europe, Southern Africa, Central America and Southern Australia. These areas are home to more than .20 percent of the world's population — that's over 1.5 billion people.

    The study looked at the current rate of global temperature increase and compared it to data from before the industrial revolution. The world has already warmed by 1℃since then. Two thirds of the affected regions could avoid significant aridification if warming is limited to 1.5℃, researchers found.

    The Paris Agreement, which was first signed in 2015, is an international agreement to control climate change. It hopes to hold the increase in the global average temperature to well below 2℃ and to pursue efforts to limit the temperature increase to 1.5℃.

    But the local protectionism makes it possible that the world may become drier and the horrific scenes of the Californian wildfires may become more common. The fire burned more than 440 square miles of Ventura and Santa Barbara counties and destroyed more than 1,000 structures after breaking out in early December.

How to Communicate as a Family

    Last night one of our 3 family dogs was hit and killed by a car in front of my mother's house.

    The dogs became, more or less, my mother's substitute 1 after her human ones grew up and moved out. The one that was killed had 2 with my mom far more than the others. She is shocked and upset. I loved the dog, 3 my true sadness currently comes from having to watch my mother endure another 4 after everything she has been through in her life. In the midst of all of this I have to sincerely5 the driver. It was not his fault. The dog chased a deer into the 6 at night. In an effort not to hit the deer he suddenly changed 7, not seeing the dog, resulting in her death. The driver 8, carefully wrapped our dog in a blanket to 9 her dignity, and carried her up to my mother s front door* He was 10 shaking and very upset. He informed my mother of11 happened and she broke down immediately. He comforted her the best a stranger could. He left his 12 and offered assistance in any way he could.

    What he really did was 13 my mother from hitting on a 14scene herself while searching for the dog. He could have very easily continued on his way, but he did something that I hope I never forget. Thank you, Stranger. You restored my 15 in humanity.

    A two-layered paint reflects infrared light (红外线) while maintaining its colour could help keep buildings and vehicles cool under hot sun. This could help reduce energy used in cooling.

    This coating (develop) by Yuan Yang at Columbia University in New York and his colleagues. It consistsa top layer, which provides the colour, and a bottom layer reflecting infrared light.

    When the sun shines on object coated with this paint, the top layer absorbs certain light, while the bottom layer reflects infrared light, preventing the object from (heat) up. A similar cooling effect can be achieved using white paint or metal mirrors, Yang says the advantage of this new paint is that it can be any colour desired. (usual) black paint absorbs heat, but painting an object with a black version of this new coating kept it about 16%: (cool) than when an object painted with commercial black paint was exposed to the same amount of sunlight.

    This new paint could be(use) in tropical locations to help keep(building) cool, as well as to prevent cars, buses and trains from getting too hot.

    You never know the difference you might make if you take the time to encourage someone. I gave up the idea of being a writer the summer before I started college. I'd been writing since I was five years old. My little friends wanted toys at that time, but I just wanted paper. Childhood passed and a box of short stories gave way to my middle school days. I wrote for a magazine and by the time I was in my eighth grade, half of the annual publications were written by me. Sometimes I'd dream about being a novelist, writing books that everyone might read. My dad was always sure that it would happen. When he read my poems or stories, his eyes welled up. "That's beautiful, honey," he always told me. "One day, the entire world will know what a gift you have." Those words encouraged me through high school to keep believing that writing was my calling.

    But somewhere along the months of my senior year, I became disappointed. The crazy injustice in this world — bad guys getting buck out on the street and doing harm again and again, changed my mind." I m going to be a lawyer in the future," I told my parents. My dad's face fell, but he kept his smile. "Whatever you do, you'll be brialliant at it," he said to me.

    One of my first classes at college was Journalism 100. One day, the professor, Bob Scheibel, assigned us a story about an apartment fire. He gave us the facts and we had a few days to write a news story.

    I was sure that I had gotten the facts right when I wrote the story. I didn't expect much feedback. But a few days later, Bob Scheibel asked me to talk to him after class. Questions raced through my mind. What had I done wrong? Had I gotten the facts mixed up? Did I miss anything critical in the details? Five minutes after the class, I found myself in front of the professor. His eyes met mine with great seriousness.
