Preschool girl lifts old man’s spirits
When Tara Wood brought her daughter to a grocery store to buy the four-year-old some cupcakes, she had no idea that would be a life-changing experience. 
As Tara pushed her daughter Norah around the store last month, she passed an old man who was by himself. The old man looked cold, until Norah shouted to him, “Hi! It’s my birthday today!” The man stopped and his demeanor changed from distant and serious to warm and friendly. “How old are you today?” the man asked. After some time talking together, Norah asked her mom to take a picture of her with her new friend “Mr Dan”, Dan Peterson, 82. They hugged and after ten minutes went their separate ways. That could have been the end of the story. But it is actually the beginning of a special relationship.
Tara posted the picture of her daughter and Mr. Dan on Facebook and someone who recognized him reached out to her with his contact information. It turned out that Mr. Dan’s wife died in March and he had been suffering from depression and anxiety ever since. The person on Facebook told Tara that it was the first time they had seen Mr. Dan smile since the death of his wife. Knowing that, Tara contacted Mr. Dan, and ever since Norah and the 82-year-old have developed a friendship unlike any other. “She has shown me a depth of love, a depth that I didn’t know existed,” Mr. Dan told the reporter.
Mr. Dan told Tara that before meeting Norah, he hadn’t had one night of uninterrupted sleep. Anxiety kept him up at all hours and made him restless. After meeting Norah, he said he now sleeps soundly. For Mr. Dan’s 82nd birthday on October 20, the mother and the daughter brought balloons and presents—and, of course, cupcakes. Mr. Dan will also spend a day around Thanksgiving with Norah and her family. “If you don’t take the time to notice people, you will never know how you can positively impact a life,” Tara Wood said.

The STAR Eco Station is an environmental science museum, a wildlife rescue center, and a shelter for endangered and illegally-traded foreign animals confiscated（没收）by the U.S. Fish and Wildlife Service. It carries out the mission “Preservation t hrough Education” by educating visitors about the preservation of the environment and the inter-dependence of all living things.
STAR Eco Station hosts field trips for schools and camps throughout Southern California. Each field trip lasts two hours, consisting of a one-hour gathering and a one-hour tour of the facility, with lessons associated with California State Science Standards.
Throughout the field trip, students learn about the latest developments in environmental protection and the ways in which wildlife interacts with various ecosystems. The students also receive an up-close and hands-on experience with our rescued foreign wildlife. The tour includes different environmental exhibits that showcase the ways students can help protect animals in the wild.
Field trips are offered on weekdays only, from 10 a.m.-12 p.m. or 12 p.m.-2 p.m. The rate is $6 per visitor, both child and adult, with a $120 minimum. We offer one free adult per 10 children for groups of 40 or more. Maximum capacity is 120 people per field trip.[
Guided tours of the STAR Eco Station introduce visitors to over two hundred rescued foreign wildlife. Each tour is led by an Eco Station staff member, and features fun animal facts, hands-on animal encounters, surprising rescue stories, environmental exhibits, and original approaches to going green. Visitors may only see the animals on a guided tour, for both your safety and the safety of our animals.
The guided tour lasts approximately 45-60 minutes. Visitors are served on a first-come, first-served basis. No reservations are required. However, tours may sell out. We suggest larger groups schedule a private tour.

Love the way you walk
Listen carefully to the footsteps in the family home, and you can probably work out who is walking about. The features most commonly used to identify people are faces, voices and fingerprints. But the way they walk is also a giveaway.
Researchers have used video cameras and computers to analyze people’s gaits, and are now quite good at it. But translating such knowledge into a practical identification system can be tricky. Cameras are often visible, are difficult to set up, require good lighting and may have their view blocked by other people. A team led by Dr. Ozanyan and Dr. Scully have been looking for a better way to recognize gait. Their answer: pressure-sensitive mats.
Such mats are nothing new. They have been part of security systems. But Ozanyan and Scully use a complicated version that can record the amount of pressure applied in different places as someone walks across it. These measurements form a pattern unique to the walker. The researchers turned to an artificial-intelligence system to recognize such patterns, and it seemed to work. In a study in 2018, they tested the system on a database of footsteps of 127 people. They found its error rate in identifying who was who was a mere 0.7%. And Scully says even without a database of footsteps to work with, the system can determine someone’s sex and, with reasonable accuracy, a subject’s age.
One application of the mat-based gait-recognition system might be in health care, particularly for the elderly. A mat placed in a nursing home or an old person’s own residence could monitor changes in an individual’s gait that indicates certain illnesses. That would provide early warning of someone being at greater risk of falling ov er.
Gait analysis might also be used as a security measure in the workplace, monitoring access to restricted areas, such as parts of military bases, server farms or laboratories dealing with dangerous materials.
Perhaps the most interesting use of the mats, though, would be in public places, such as airports. For that to work, the footsteps of those to be recognized would need to have been stored in a database, which would be harder to arrange than the collection of photographs and fingerprints that existing airport security systems rely on. Many aircrew or preregistered frequent flyers would welcome anything that speeded up one of the most tiresome parts of modern travel.

A. Research equipment. B. Research findings.

A. collect data B. ensure safety

C. keep track of travelling frequency D. warn passengers of possible dangers
41. The main purpose of the passage is to _____.
A. compare and educate B. examine and assess

Overtourism: A growing global problem
The summer holidays are in full swing—and protests against overtourism have begun in a number of popular European cities. Barcelona, in particular, is at the centre of th ese mounting concerns about the rapid growth of tourism in cities, especially during peak holiday periods. In fact, there were 30 million overnight visitors in 2017, compared to a resident population of 1,625,137 in Barcelona.
While many tourists want to “live like a local” during their visits, the residents of many tourism-dependent destinations are seeing the unique sense of place that characterised their home towns vanish beneath a wave of souvenir shops, crowds, tour buses and noisy bars. Overtourism is harming the landscape, damaging beaches, and pricing residents out of the housing market. It is a hugely complex issue that is often oversimplified.
It can have an impact in multiple ways. The international cruise(游轮) industry, for example, delivers thousands of passengers daily to destination ports. While comparatively little is returned to communities, cruise activity creates physical and visual pollution.
City residents also bear the cost of tourism growth. As cities transform to offer service to tourists, the global travel supply chain advances. This goes with increasing property speculation(房产投机) and rising costs of living for local communities. Airbnb, for example, has been accused of reducing housing affordability and displacing residents.
In addition, overcrowding and the establishment of typical tourism-focused businesses, such as clubs, bars and souvenir shops, overpower local businesses—and noisy and unmanageable tourist behaviour is common. This weakens the uniqueness of destinations and leads to crowd and waste management pressures.
Clearly, tourism brings jobs, investment and economic benefits to destinations. But overtourism occurs when tourism expansion fails to acknowledge that there are limits. Local government and planning authorities have so far been powerless to deal with the irresistible influence of the global tourism supply chain. This has led to widespread “tourist-phobia”—first described by Manuel Delgado more than a decade ago as a mixture of rejection, mistrust and disrespect for tourists.
Dealing with overtourism must now be a priority. Managing the flow of tourists seems an
