When the shrill (尖锐的) ring of the phone echoed (回响) through the living room, Jane was still sleeping. She slowly opened her sleepy eyes and looked at the clock on the bedside table. It was already nine o’clock! Though still sleepy, Jane knew she had to get up because her mother had been working in her office day and night for several days and she couldn’t expect her younger brother Tom, who was sleeping like a pig, to answer the phone. She quickly put on a coat and dashed into the living room. As she picked up the receiver, on the other end came the warm greeting, “Good morning, my dear!”
It was the voice of her father, a sea man who seldom returned home due to his duties earning money to support the family. On hearing her father’s voice, Jane’s sleepiness disappeared.
Born in a not-so-rich family, Jane and Tom felt the stress of life, but they were happy to enjoy the family atmosphere. At school, they were straight-A students and took part in various after-school activities, earning the pride of their loved ones.
“Good morning, Dad. Why are you calling so early on a weekend?” Jane inquired, pretending to be slightly annoyed. “Tom and I have been very nice recently.” “My dear, today is your mother’s birthday. I have ordered a cake online and it will arrive at our doorstep in the late afternoon. Do remember to take the cake. It is my surprise for your mother.”
Upon hearing her father’s words, Jane felt a twinge of embarrassment. How could she have forgotten such an important day!
While chatting with her father, Jane’s gaze (凝视) wandered around the room and saw a lot of dirty clothes scattered (散落) on the sofa. The floor hadn’t been cleaned for a few days since her mother had been too busy with work this week to attend to such domestic matters.
Glancing at the clock again, Jane realized she still had enough time to prepare a surprise for her mother.
“Well, Dad, now I’m going to wake Tom up. We will give Mum a surprise, too!” Jane said and hung up the telephone.

Puzzles come in a huge range of sizes and difficulty levels. For beginners, a 100-piece puzzle is usually a good starting point.
For a real test, puzzles that have 1,000 pieces or more are a tough task and it’s best to complete them with friends or family if you can. Choosing a scene that interests you, such as a favourite film, sport or location, can help keep you interested and determined to work to the final piece. You can get fun educational puzzles, too.
Some of the best places to pick up puzzles are charity shops. They’re often on sale for less than £5. Once you have completed a puzzle, it’s nice to exchange it with a friend.
| A．So others can have a go. |
| B．You can’t beat a good puzzle. |
| C．Some companies make personalized puzzles. |
| D．However, a good start doesn’t always lead to a good result. |
| E．Most people like to start by getting the four edges of a puzzle laid out. |
| F．It can get you used to sorting out how the shapes, patterns and colors go together. |
| G．For example, you may try a map of the world or historical timelines. |
4 . Artificial intelligence (AI) is showing promise in earthquake prediction, challenging the long-held belief that it is impossible. Researchers at the University of Texas, Austin, have developed an AI algorithm (算法) that correctly predicted 70% of earthquakes a week in advance during a trial in China and provided accurate strength calculations for the predicted earthquakes.
The research team adopted a relatively simple machine learning approach. The AI was provided with a set of statistical features based on the team’s knowledge of earthquake physics, and then instructed to train itself using a five-year database of earthquake recordings. Once trained, the AI provided its prediction by listening for signs of incoming earthquakes within the background rumblings (隆隆声) in the Earth.
This work is clearly a milestone in research for AI-driven earthquake prediction. “You don’t see earthquakes coming,” explains Alexandros Savvaidis, a senior research scientist who leads the Texas Seismological Network Program (TexNet). “It’s a matter of milliseconds, and the only thing you can control is how prepared you are. Even with the 70% accuracy, that’s a huge result and could help minimize economic and human losses and has the potential to remarkably improve earthquake preparation worldwide.”
While it is unknown whether the same approach will work at other locations, the researchers are confident that their AI algorithm could produce more accurate predictions if used in areas with reliable earthquake tracking networks. The next step is to test artificial intelligence in Texas, since UT’s Bureau TexNet has 300 earthquake stations and over six years worth of continuous records, making it an ideal location for these purposes.
Eventually, the authors hope to combine the system with physics-based models. This strategy could prove especially important where data is poor or lacking. “That may be a long way off, but many advances such as this one, taken together, are what moves science forward,” concludes Scott Tinker, the bureau’s director.
