Dear Mr. Pick,

Yours,

Li Hua

    I agree with Mr. Zhang's idea sport can help improve health and mood people of all ages. I had a similar experience last year. I quit the basketball team I thought I didn't have enough time for it. After (quit) I felt sad and had no energy. I quickly lost my (fit) too. I spoke to my parents who agreed I should rejoin the team. Now I play every week and I'm happy and healthy.

    It's about 250 miles from the hills of west-central Iowa to Ehlers' home in Minnesota. During the long trip home, following a weekend of hunting. Ehlers 1about the small dog he had seen 2 alongside the road. He had 3 to coax(哄) the dog to him but, frightened, it had 4.

    Back home, Ehlers was troubled by that 5 dog. So, four days later, he called his friend Greg, and the two drove 6. After a long and careful 7, Greg saw, across a field, the dog moving 8 away. Ehlers eventually succeeded in coaxing the animal to him. Nervousness and fear were replaced with 9. It just started licking(舔) Ehlers' face.

    A local farmer told them the dog sounded like one 10 as lost in the local paper. The ad had a 11 number for a town in southern Michigan. Ehlers 12 the number of Jeff and Lisa to tell them he had 13 their dog.

    Jeff had 14 in Iowa before Thanksgiving with his dog, Rosie, but the gun shots had scared the dog off. Jeff searched 15 for Rosie in the next four days.

    Ehlers returned to Minnesota, and then drove 100 miles to Minneapolis to put Rosie on a flight to Michigan. "It's good to know there's still someone out there who 16 enough to go to that kind of 17,"says Lisa of Ehlers' rescue 18.

    "I figured whoever lost the dog was probably just as 19 to it as I am to my dogs," says Ehlers. "If it had been my dog, I'd hope that somebody would be 20 to go that extra mile."

Sustainability(可持续性), one of the biggest topics of the last decade, has become the ray of hope to protect the planet. It's a topic we can't ignore and we must act now in a more sustainable way.

What does that mean for the world of technology? E-waste is one of the planet's biggest contributing waste problems.

Not only e-waste, but the materials that go into tech products are part of the problem. Take the smartphone industry for example, dozens of metals, minerals which have to be taken from the earth (including 16 of 17 rare metals) go into making phones. And with demand for mobile phones bigger than ever, it's a problem that needs to be solved.

With a challenge comes an opportunity, and there's already some progress happening - great news for those of us wanting to be more sustainable with our tech. People used to turn their noses up at the idea of a second-hand product, but there's been a huge increase in demand for refurbished tech(翻新技术). For example, refurbished smartphone sales in the US have risen by 28% in the last 12 months while brand new sales have fallen by 21%.

Many communities are making an effort to deal with e-waste as well. Cities, schools, or churches will sometimes hold events to collect e-waste and send it to recycling centers. Some companies even offer buy-back programs where people will be given cash if they turn in old devices.

So the next time you want to deal with your e-waste, whether a smartphone, a laptop, an MP4 player or other, consider the more environmentally-friendly choices. It is possible to be sustainable with your tech after all.

    Following the outbreak of the novel coronavirus pneumonia (NCP), also named COVID-19 by WHO, there is a general fear of the unknown virus as its full effects remain to be seen. Fever, coughing, sore throat, difficulty breathing —the NCP's symptoms are similar to the common cold or the flu, but it's potentially more dangerous.

    Viruses could be deadly, like HIV and Ebola. But what are viruses? How can they cause so much trouble?

    Viruses are non-living organisms (有机体) approximately one-millionth of an inch long. Unlike human cells or bacteria, they can't reproduce on their own. Instead, they invade the cells of living organisms to reproduce, spread and take over.

    Viruses can infect every living thing – from plants and animals down to the smallest bacteria. For this reason, they always have the potential to be dangerous to human life. Sometimes a virus can cause a disease so serious that it is fatal. Other viral infections trigger no noticeable reaction.

    Viruses lie around our environment all of the time, waiting for a host cell to come along. They can enter our bodies by the nose, mouth, eyes or breaks in the skin. Once inside, they try to find a host cell to infect. For example, HIV, which causes AIDS, attacks the T-cells of the immune system.

    But the basic question is, where did viruses first come from? Until now, no clear explanation for their origin exists. "Tracing the origins of viruses is difficult", Ed Rybicki, a virologist(病毒学家) at the University of Cape Town in South Africa, told Scientific American, "because viruses don't leave fossils and because of the tricks they use to make copies of themselves within the cells they've invaded".

    However, there are three main hypotheses (假说) to explain the origin of viruses. First, viruses started as independent organisms, then became parasites (寄生者). Second, viruses evolved from pieces of DNA or RNA that "escaped" from larger organisms. Third, viruses co-evolved with their host cells, which means they existed alongside these cells.

    For the time being, these are only theories. The technology and evidence we have today cannot be used to test these theories and identify the most plausible explanation. Continuing studies may provide us with clearer answers. Or future studies may reveal that the answer is even murkier (含糊不清的) than it now appears.

    When I entered college, I took Professor Black's poetry class. Even though I finished every task and1no classes, I earned a “C” at the end of the term. Frustrated, I went to his office and asked in a low voice, my knees2, “Do I have any talent?” He was a kind person. He pushed his hair behind his ears3he was thinking. “Probably not,” he said4. “Thank you,” I said, feeling like a grafted (嫁接的) apple tree: part of me discouraged, another part5to accept it.

    The latter part led me to another poetry class by Professor White. This time, I earned an “A”. Professor White told me that6in his class earned an “A”. I was shocked. His7approach reminded me of Professor Black, from whom I learned teachers don't hold the keys to their students'8.

    Every human being is9born with talent. Some10souls are born with many talents. People are11to subjects they have a gift for,12nearly everyone in the writing class has writing talent.

    But no one can13whether or when talent will bloom (绽放) into art that others14as good. Some people bloom early, others late, some not at all. Artists must have enough15to make art, and trust their own pleasure in making it. It was really the faith in myself as well as the16in writing poems that helped me17many years of writing poems without being recognized.

    I've been teaching creative writing for more than 30 years. Students sometimes ask me, “Do I have talent?” I tell them my18, and say, “Of course you do. But just19writing no matter whether anyone approves (认可,赞成)-or even 20.”
