2 . Advances in AI and machine learning have sparked interest from governments that would like to use these tools for patrolling (巡查) purposefully before hand to prevent crime. However, early efforts at crime prediction have been controversial, because they do not allow for systematic biases (偏见) in police enforcement and its complex relationship with crime and society.
University of Chicago (UC) data and social scientists have developed a new algorithm (算法) that forecasts crime by learning patterns in time and geographic locations from public data on violent and property crimes. It has demonstrated success at predicting future crimes one week in advance with approximately 90% accuracy.
The new tool was tested and validated using historical data from the City of Chicago around two broad categories of reported events: violent crimes and property crimes.
The new model isolates crime by looking at the time and spatial coordinates (坐标) of separate events and detecting patterns to predict future events. It divides the city into spatial sections roughly 1,000 feet across and predicts crime within these areas instead of relying on traditional neighborhood or political boundaries, which are also subject to bias. The model performed just as well with data from seven other US cities.
Ishanu Chattopadhyay, senior author of the study, is careful to note that the tool’s accuracy does not mean that it should be used to direct law enforcement, with police departments using it to flock to neighborhoods ahead of time to stop crime. Instead, it should be added to a toolbox of urban policies and policing strategies to address crime.
“We created a digital twin of urban environments. If you feed it data from what happened in the past, it will tell you what’s going to happen in future. It’s not magical; there are limitations, but we tested it and it works well,” Chattopadhyay said. “Now you can use this as a model tool to see what happens if crime goes up in one area, or there is increased enforcement in another area. If you apply all these different data, you can see how the system evolves in response.”

In DeAnza Community College, 15 minutes’ drive from the university Trevor Wallace studied in, his beloved grandmother had worked there. When she was alive, she was a respected learning disabilities specialist and instructor. In recognition of her work, her co-workers dedicated a large, cement angel fountain with a plaque (匾) saying Heart’s Garden: In Memory of Marilyn Rosenthal. That was in 1999.
Trevor knew well that the fountain meant a lot to his mom, Sarene. She was only 36 when her mom died. At the sight of anything to do with her mother, she would tell stories or anecdotes related, especially the fountain. Though she cherished it, living six hours away, she didn’t have the opportunity to visit it regularly.
As time went on, the fountain was hidden under trees, falling into disrepair----the statue’s bowl at its base broken; cement benches nearby damaged; the water pump blocked with leaves and the surrounding area littered with dead leaves and trash, etc.
Finally, in 2013, it was once repaired by one of the school gatekeepers, who thought she was popular with colleagues and students when she was alive. After knowing the repair, Sarene and Trevor took the 300-mile trip to visit it. On a quiet afternoon, they posed for a photo together. Sarene recalled, “We sat watching the fountain for a while. The water welled over then it went into the bowls. It was so peaceful.”
Flash forward to 2015. When deciding what to give his mom for Mother’s Day, the fountain came to mind. Trevor called Sarene that Sunday to wish her a happy Mother’s Day and told her to expect a surprise. Then he drove to DeAnza with his camera, tripod, and two sponges.
When he arrived, the fountain was covered with leaves and piled with dirt, in worse shape than he had expected. Motivated by memories of his late grandmother, whom he called “Bubby”, he set up his camera on the tripod, checked the lighting and took a before shot. Then his hand-scrubbing (手工擦洗) work began.

6 . It is quite true that nowadays more and more people have come to realize the importance of health. On the other hand, being healthier can be a huge challenge, especially if you don’t have the time or the energy.
Eat your meals with your non-dominant hand.
Which is your non-dominant hand? For example, if you’re a right-hander, then your left hand is. Usually fork in your left hand, right? OK!
Add in healthy food.
You can buy those Milano cookies, but also make an effort to buy frozen fruits for smoothies (奶昔) and snap pea crisps to snack on, too.
Drink a glass of water before every meal.
Water will fill you up a little bit, so you won’t be hungry as a wolf at meal. Make it a habit to keep a water bottle nearby at all times, whether you’re in your house or on the go. That we should drink at least 8 cups of water every day makes sense.
Drink coffee.
Right!
People who eat on smaller plates end up eating less food. Buy a few inexpensive smaller plates and bowls if yours are large. You’ll think you’ve eaten more than you have.
Besides, just stretching your legs after meals every day will help a lot more.
A.Eat on smaller plates. |
B.Never a coach potato! |
C.A lucky dog you are now. |
D.Caffeine truly refreshes you. |
E.Stop eating when you feel full, never overeat. |
F.Try using your right hand as your fork hand, rather than your left one. |
G.Over time, fewer cookies and more healthy snacks you will have on hand. |
7 . Solar power is one of the fastest growing sources of renewable power globally these years. Solar photothermal (光热) and solar photovoltaic (PV光伏)are both technical forms.
The thermal power station adopts the generation mode of “light--heat--electricity”. Thousands of heliostats (定日镜) reflect the sunlight to the surface of the heat absorber on the top of the solar tower. The concentrated sunlight is then used either directly as a source of heat, as in solar water heating, or to drive a heat cycle such as a Sterling Engine. PVs use semi-conductor technology to directly convert sunlight into electricity. The PV line is connected to the direct current (DC) distribution cabinet in parallel through the DC combiner box. After confluence (汇合), it is connected to the DC input end of the inverter to convert DC into alternating current (AC). The AC output end of the inverter is connected to the AC distribution cabinet and directly connected to the user side through the AC distribution cabinet.
Additionally, since solar thermal directly produces heat, it can store thermal energy into various media. Therefore, solar thermal can potentially generate power 24 hours a day. On the other hand, PVs only operate when the sun is shining, and must be coupled either with other power generation mechanisms to ensure a constant supply of electricity.
The scale of PV power generation can be large or small, ranging from thousands of watts to hundreds of megawatts, but photothermal power generation is typical economies of scale. With the increase of scale, the lower the power generation cost.
PV power generation is less limited by region, for the sun shines on the earth. Compared with other sources of renewable power, the PV system is safe and reliable as well as eco-friendly. Since it can be convenient for local power generation and power supply, you do not worry about consuming fuel or erecting transmission lines. A small PV power can be constructed in a short period with no noise or low pollution.
