Dear world, here is why you should care about astronomy. It’s true that its advances benefit millions of people across the world. It has developed technology now to track where your 【1】 (pack) goes, to determine where you are and so 【2】.

But all of these are mere second thoughts, 【3】 (benefit) that have occurred without the primary intention of the maker. And that is 【4】 makes astronomy beautiful. To study something - not because we’re looking to gain anything in particular, but purely 【5】 (enjoy) natural wonders - 【6】 (be) all that makes us human. Doing work for the work itself creates room for mindfulness and joy.

I 【7】 (firm) believe that astronomy has a spiritual dimension in the sense of how it connects us with something bigger than ourselves. Because 【8】 astronomy, we now know exactly when the Universe 【9】 (come) into existence. And we’ve spotted thousands of planets orbiting other stars. It has explained mysteries (神秘的事物) 【10】 (confuse) us for thousands of years, but even more significant, it has opened up more mysteries than any of us can study in our lifetime.

“We know their eyes are quite sensitive to polarized light (偏振光), and the sky has a particular pattern of polarized light, connected with the position of the sun.” says Barbara Webb, a bioroboticist at the University of Edinburgh. You can see polarized light firsthand if you take a pair of polarized sunglasses and spin them against the sky --- the light passing through the lenses changes. Webb says the insects have polarization like that built into flat sides of their compound eyes. “You can think of it as the equal of having a little polarization directional filter (滤镜) over them or lots of sunglasses pointed in different directions.”

But Webb was curious about whether there's really enough information in the sky to give insects an accurate sense of direction. So her team built a sensor modeled after a desert ant eye and put it under artificial light meant to simulate the sky. They then fed that sensor input into a model meant to copy the brains of desert ants and other insects with a sky compass. And they found that with the insects' natural sensing and processing equipment, they can likely sense compass direction down to just a couple degrees of error.

A system based on that of insects could someday be a cheap, low-energy alternative to GPS. “Insects have very tiny brains, a brain that's using hardly any energy. And yet they're still able to navigate better than we can with GPS, which is a huge system.” Webb is now working on building a robot that can, like the desert ant, use light to get its direction. Although after sundown, it may have to ask for directions.

I warned Chris to take care, he slipped into the lake. I was too frightening to know what to do. I cried for help anxious. Hearing my cries, a young man rushed over, jump into the lake to save Chris. At last, he was out of the water and we immediately sent him to the near hospital. After short while, Chris’ parents arrived. They expressed their thank to the young man. How a respectable man!

With the graduation day approaching, memory are flooding back to me. I remember how unwillingly I was to enter the classroom. “If I have studied harder before, I would have gone to a better senior high school,” I said it to myself. However, I later realized I fell in love with a school.

The campus scenery is pleasant. The antique pavilion (亭子), where stands on a small hillside, impresses me most. Surrounded green trees, I can admire the beautiful sunrise and sunset. I often wander around the charming pond and see myself reflecting in its transparent water. Any pains I have are smoothed and float away. The kind teachers and easy-going classmates also warm my heart and cheer me up when I am in low spirits.

Every time I recall my unforgettable moments, I smile. We’ve all grew over these three years.

Life is a long journey, and our problems are like rocks on the road. How do I handle it? Most of the time, I turn to my teachers to help or write about my problems online instead of share my troubles with my parents. They go to work early and come home lately. They look so tiring after a day's work. Although I tell them about my difficulty, they may turn a deaf ear to me. Therefore, I still want to tell them all my troubles someday. I don't expect them to give me any useful advices. I just want them listen to me and comfort me.

Bert had health issues in his later years that limited his mobility, and when he lost his vision three years ago, his attachment to his radio and Francesa became more pronounced. He just loved listening to Mike talk about sports and his Yankees each afternoon. Those hours brought him so much pleasure.

Of course, Mike will be leaving Dec.15,2017 after 30 years at the station. Mike lives in the same community where I work on Long Island, and I have gotten to know him over the past 20 years. So when my grandfather was approaching his special birthday the year before last year, I asked Mike for a favor: to call Bert and wish him a happy birthday.

Mike agreed without hesitation. Two days before the special day, Mike stopped at my workplace. I called Bert at his nursing home and put Mike on the phone. It was a complete surprise to Bert. Mike spent more than 10 minutes wishing Bert a happy birthday and, of course, talking about the Yankees.

When my family celebrated Bert’s birthday two days later, he couldn’t stop talking about the phone call. Over his lifetime, he said it was one of the nicest things anyone had ever done for him.

Unfortunately, Ben’s health declined last year and he passed away July 13,2017. But even in his final months in the hospital and nursing home,he always had a radio set to WFAN to listen each afternoon to Mike Francesa.And he also had the memory of that special phone call for his 90th birthday.
