An undersea tunnel (n.隧道) of a high-speed railway was completed in South China on Friday,(set) a new record in the construction of high-speed railway tunnels in China.
The Zhanjiang Bay (湛江湾) Undersea Tunnel, a key project of the Guangzhou-Zhanjiang High-speed Railway,(complete) after 33 months of construction, marking a significant milestone in the construction of the new railway.
The Zhanjiang Bay Undersea Tunnel spans (v.横跨)total length of 9,640 meters. It is designed as a single tunnel with double tracks, crossing the seabed of the Zhanjiang Bay and the urban area of Zhanjiang. It crosses a 2,500-meter sea section and a 5,051-meter section of land.(especial), the tunnel is China's(long) single-headed undersea high-speed railway shield tunnel (盾构隧道), showcasing the country's remarkable engineering techniques.
"Single-headed shield (单头盾构) refers to the method of using a single tunnel boring machine (隧道掘进机) (dig) continuously from one end to the other," said Yin Yihao, an engineer from China Railway's 14th Bureau Group, which was responsible for the tunnel's construction. Yin added that the traditional methods were not applied in the Zhanjiang Bay Undersea Tunnel due to the complicated geological conditions andthe single-headed shield tunnel was (safe) and more efficient in this case.
Wu Chunzhao, a senior engineer of the China Railway Design Company,(explain) the reason for building an undersea tunnel instead of a bridge. "Building a tunnel preserves (v.保护) the beautiful urban skyline of the Zhanjiang Bay,avoids the impact of the project on the marine (adj.海洋的) ecological environment," he said. Wu also noted (v.指出) that a bridge will affect the large ships' navigation, but the tunnel will not do this.
The tunnel is a key project of a high-speed railway linking Guangzhou and Zhanjiang in Guangdong.
There is growing evidence to show that our past knowledge about Mars was not always the case. Now European researchers say they have discovered the first evidence of a huge groundwater system that once existed below the planet's surface.
Anew study was carried out by Francesco Salese and his team, who studied images of 24 deep craters (n.弹坑) in the northern half of the Red Planet. These pictures were captured by ESA's Mars Express orbiter (n.宇宙飞船), which was launched in 2003. The study provides the first geological proof that Mars once had a "planet-wide groundwater system."
According to Salese, scientific evidence already suggests Mars was once a watery world. His team says the images showed that large amounts of successive groundwater activity connected the areas they studied. Evidence of basins and coastlines was also found on the surface of Mars, supporting the idea that water was once present. He added that all the basins seemed to reach about the same height.
Scientists have yet to find out what happened to all that water. And the complex history of water on Mars has linked to whether or not life ever existed on it. During the latest study, researchers also discovered evidence of minerals within some of the identified (adj.被识别的) bodies of water.
The researchers say the findings adds weight to the idea that the water basins on Mars may have once held the materials required to support life. Some of this material could still be buried on Mars, providing possible evidence of life during future exploration. Francesco Salese believes the latest findings could also help us learn new things about our own planet.
Secrets, whether they're juicy, shocking or just plain funny, nothing compares to the thrill of opening up or listening to a friend's confession (n.坦白). When a pal bares his heart to you, you can't help but feel trusted and special. In fact, you're a lot more likely now to tell him something you wouldn't tell just anyone. When you're first getting to know a new friend, start with small secrets.
No secret is ever 100 water-proof, but you can take steps to prevent getting your feelings hurt. First, when something you're telling a friend is a secret, always say so. Every time when you share something confidential (adj.保密的), tell her that this is "for your ears only." Also, don't assume (v.假定,认为) someone will keep your secrets just because you know some of hers. Some people just have a tendency to blurt things out, which is why it pays to get a feel for how good a secret-keeper your friend is. Finally, make sure you get a reputation as someone who takes secrets seriously.
It's not worth breaking a promise to a friend, but if a secret is too big for you to carry alone, you have a responsibility to tell someone. There are probably a few details about your life that you don't feel like sharing, even with your closest friends. If the secret isn't hurting you or your friendship, silence is golden. If you're hiding something big and constantly worrying about your secret being leaked, it may be time to just spill (v.溢出) your beans. Taking control of a secret that's eating you up inside isn't easy.
So it seems clear that knowing when to let the secret out and when to zip your lips will help you a lot.

My earliest reading memory takes me back to being five years old, sitting in my grandfather's cozy study. He would read to me from his French-translated copy of Rudyard Kipling's The Jungle Book. I was so familiar with the stories that I could correct him word-for-word if he tried to change something.
Growing up, my favorite book was Ray Bradbury's Something Wicked This Way Comes. It was a treasure for an imaginative and lonely child like me. The book was filled with magical elements: a magical carousel, monsters, and the charming scent of autumn leaves lying in the sun. The language was as crisp and sweet as an October apple, awakening in me a deep passion for words and the magic they could bring out. I've reread it regularly and it never fails to satisfy me.
In my adult years, I revisited Emily Brontë's Wuthering Heights. When I first read it at 16, I perceived it as a love story. However, rereading it as an adult, I was struck by how different it seemed to me, and how much of the humour I'd missed. Now I love its poetry. And the love story not only exists between the characters but between Brontë and the North York Moors.
James Joyce's Ulysses was a book I came back to after 40 years. Initially, at 15, I found it ugly, depressing, and dull, and I hated it. It took me four decades to return to it, and this time, I found myself understanding and beginning to appreciate it. I could see the details, the mythic parallels, the references to different writing styles, and the groundbreaking technique.
Though some exceptional books can develop and grow alongside us, others fall by the wayside. I've revisited so many childhood favourites only to find the magic gone, but I'm usually happy to leave the book behind. I've taken from it what I need.
The Making of a Believer
It was Christmas Eve morning, and I awoke with a mission: to find my lost cat, Baby-Girl, who is chubby and cute, fond of sitting in her one-and-only spot near the nearth (壁炉). AS I got ready, I could hear icy rain pouring down. I said a quick prayer for Baby-Girl. She was out there somewhere in the storm, I could just feel it. Sure, it had been six months since she'd gone missing, but I still had faith. It was the season for miracles, after all.
That summer, my sweet cat had disappeared from my parents' house in Indiana. Baby-Girl had been staying with them. At the time, I lived and worked in Washington, D. C. Baby-Girl had gotten out of my parents' house three days before I was set to fly back home to pick her up.
My dad and I spent that entire visit searching for her. Dad was the family's resident "realistic", which mean the spent a whole lot of time trying to prepare me for the worst. She's either been hit by a car or been taken in by someone who found her" he said. I rolled my eyes. Dad always supported me, but he was so skepticat. He could do with a little more faith!
Besides, though I couldn't explain it, I knew I'd see her Baby-Girl again. If any cat could do the impossible, it was my Baby-Girl. Even after T returned to D. C. without her and the weeks stretched into months, deep down I had this feeling that we'd be reunited.
How, home again for the holidays, I was de tem mined to pick up my search. I grabbed Baby-Girl's cat carrier and loaded it into the car, then persuaded Dad to drive me to the shelter, hoping she'd been found.
"Sharon, you have to be realistic," my dad said as we headed to the garage. "She's been gone too long. You're not going to find her."
"Well, I just have a feeling," I said
Dad raised an eyebrow a she climbed into the driver's seat to take me to the shelter.

We were led to the room where the abandoned cats lived.
Shortly after, my shocked Dad drove us back home.
