If there is any such thing as a sea monster, chances are that it looks much like a frilled shark (皱鳃鲨)! This fearsome but interesting creature is one of the most rarely sighted species on earth. Let’s take a closer look at the habitat, appearance and feeding behavior of the frilled shark.
While very little is known about the frilled shark, it is thought to live in the deepest, darkest parts of the Atlantic and Pacific oceans and only come to the surface when sick or injured. It is believed that they are able to survive at a depth of about 5,150 feet but are more commonly found in waters 50-200 feet deep. There is a small but convincing body of research that suggests the frilled shark is a vertical migrator, moving from deep to deeper waters on a regular basis.
While this mysterious beast is called a shark, many believe it looks more like an eel with a long, slim body about five to six feet in length. It has a head that’s triangular in shape similar to that of a poisonous snake and large oval eyes giving off a strange and frightening green light. The unusual creature has six pairs of gills (鳃), each with the frilled edges for which the sea monster was named.
The feeding behavior of the frilled shark has never been studied or even observed by human eyes. However, it is almost certainly a predator (食肉动物). After all, researchers believe, why else would it need 300 sharp teeth?! Scientists theorize that these dangerous teeth make it possible for a slow moving fish like the frilled shark to catch squid and other deep-sea creatures.
As research into the habitat, appearance and feeding behavior of this strange creature continues, there’s a good chance that we will gain a full understanding of this unusual species one day. Until then, the frilled shark remains one of the great mysteries of the deep.

In 2010，my mother-in-law gave me her rather simple but graceful, antique “secretary desk.” The desk easily fit into the tiny room at the top of the stairs. I felt so secure, and confident when I sat down and began each writing session. Despite the desk’s appeal, its limited storage capacity meant that I often put file folders and books on the small floor space around me. After each writing session, I painstakingly gathered the tools of the trade and placed them on a nearby shelf until the next session.
A few years into my writing journey, we moved into a bigger home and I acquired my own office. My husband, Bill offered on more than one occasion to buy me a new desk for my office, but I ignored his offer.
One day, we stopped at the local office supply store. Bill found what he thought was the perfect desk for me. “ I want to buy this for you, sweetie. My writer needs a bigger desk.” He hugged me.
“Thanks, but I don’t want a bigger desk!” I said.
“Why don’t you want a bigger desk?” he said. “You must be afraid of something.”
“I’m not afraid of anything,” I said. “ Like I said, I really like my little desk. So don’t ask me again”.
He didn’t.
A few weeks later, while working in my new office, I looked around at the folders , books and papers lying all over my office floor but couldn’t find what needed to meet a contest deadline. My heart raced. I looked around my office. The room basically swallowed the tiny desk, making it look slightly out of place. Maybe I did need a bigger desk. Was Bill right? Was I afraid of something?
Unable to write, I pulled C.JoyBell C.’s book of poetry, All Things Dance Like Dragonflies, from the bookshelf. I flipped through its pages, and her words about faith jumped off the page into my heart. She talked about how she had trained herself to love the feeling of not knowing where she was going, and just trusting that as she opened up her wings and flew off in an unknown direction, things would work out.
At that moment, I recognized that a bigger desk symbolized bigger possibilities, stepping out in faith, and leaving my comfort zone.

A.My writing journey. B.On the wings of change.
C.Why I love writing. D.A quarrel between my husband and I.
We have all imagined what it might be like to go into space and to land on Mars. Now at the Kennedy Space Center Visitor Complex in Florida you and your family can live it. There are two parts to the new program, the Astronaut Training Experience (ATX) and Mars Base 1.
The Astronaut Training Experience
The virtual reality (虚拟现实) Walk-on-Mars, Land-and-Drive-on-Mars full-motion simulator (全动态模拟器) and Spacewalk Training are all parts of the ATX. If you or your children already love science and have a deep interest in space, this will bring that love to life. Prepare for your mission to Mars by training like a real NASA astronaut headed to space. Ever wanted to take a spacewalk? How about a zero-gravity experience, where you fix space equipment like a real astronaut would?
You can do any of these as “mini missions” if you don’t have time to do them all at once. Each stage takes about 30-45 minutes.
Mars Base 1
What could be cooler than a day actually spent on Mars? Not an hour or a walk through a display, but a real day working and surviving on the planet’s surface doing real science? Become a “rookie (新手) astronaut” participating in simulations and scientific research to grow and analyze crops in the Mars Botany Lab, or use robots to accomplish tasks. Yes, you actually take part in these activities, and grow real food that is really used and consumed.
Both the ATX and Mars Base 1 offer the magic of space travel without leaving the ground.
