Thanks     4     his mother, Shen Kuo received a formal education in his childhood. He was diligent and he read so much that he suffered eye pain later in life. While in his     5     (thirty), Shen Kuo frequently dreamed of a place. In the dream, he climbed a hill, the top of     6     was covered with brightly colored flowers and trees.

Later on, when     8     (travel) around, he was shocked to find a piece of land that was     9     (exact)the one in his dream.

3 . Steve Greig lost his dog Wolfgang seven years ago, then his life changed forever. Since that loss, he has adopted more than a dozen dogs, all of whom have been in their last few years of life. He chose to rescue senior dogs because they otherwise wouldn't have had a home.

Greig started posting family photos of his animals on Instagram, and his following has grown quickly to more million Instagram followers. Moreover, he has a pig, two rabbits, two ducks, four chickens, two cats, and a 22-kilogram turkey.

His mission didn't begin with the intention of going viral, but rather simply to honour Wolfgang's memory. He wanted something good to come out of the tragedy, so he went to a local animal shelter and adopted the oldest dog there. After that, he started photographing his daily life with his animals.

He also didn't originally intend to inspire others, but that's exactly what happened. Shortly after he started posting, his inbox filled with messages from people who had also adopted senior dogs. His fame led to a book, which teaches kids about valuing what is old instead of looking for the next new thing. He now keeps nine elderly dogs at a time, and when they pass away, he adopts new ones in their honour and in honour of Wolfgang.

Part of Greig's popularity on social media is from his family portraits and his updates of the animals, but the other part is from the unique names he gives his pets. Besides Bikini and Tofu, which he named “because it was funny”, his other pets have “elderly” names like Loretta and Wilhelmina. He has a new dog named Edsel after the failed Ford model from 1958. He chose the name “because when it originally came out it was worthless, but now it's a collector's item”.   His attitude towards Edsel is his attitude towards all of his pets, and it demonstrates his value for life in general.

Greig's touching experience with older animals has helped him value humanity even more. Whether he's helping an overlooked and forgotten aging dog or homeless person, there's a common point: sympathy. “They deserve attention, conversation, and help. ” he says.

4 . In a highly-connected world where your phone is always with you, information is being collected and shared every second.“So what?” you say. “I have nothing to hide.”     1     According to some experts, people may not understand the scope (范围) of the problem.

The problem is that while companies and data brokers are hovering up all the information they can, there are no laws governing what they can do with that information.     2     Someone knowing that you ordered three extra-large pizzas for dinner last Friday night may seem harm-less enough, but there's a deeper principle at play.     3     As cyber expert Bruce Schneier says, “Privacy is a basic human right, and a requirement for maintaining the human condition with dignity and respect.”

    4     We click “I Agree” without reading the user agreements. We say we will do one of those privacy checkups one day. but we never quite get around to it. And that means your personal information could be used against you in the future in ways you can't imagine today.

So what can you do to protect yourself?     5     If you' re worried about your personal information getting lifted, don't hand over your name, address, or phone number easily. Besides, choose a paper receipt or no receipt rather than getting one via text or e-mail. To stop your phone acting as a tracker, also turn off Location Services for all apps except maps andothers that expressly need to know where you are. You can do this in settings, under Privacy and Location.
