If your cat often waits too long outside a t the door waiting to be let in, what would you do? Arkaitz Garro, a WeTransfer software engineer in Holland, decided to use his skills to solve the problem. Instead of setting up a good old catflap（猫洞） on his door, he went for a more hightech solution involving artificial intelligence, motiondetection sensors, face recognition software and a messaging app. It may be overkill, but Arkait z claims that it only took him a few hours to do it, as all the hardware and software he used are readily available.
It all started a few years ago, when Garro and his wife spotted a cat in their back balcony. Not knowing if it had been abandoned, lost by its owner, or simply homeless, they took it in, but also posted some pictures of it around their neighborhood, in case someone was looking for it.
“We found out that the cat had an owner, just a few houses away and he was very happy to‘share’ the cat with us. Now it has two families who love him,” Arkaitz said.“So, he has developed a schedule to come at around specific times.”
The problem was that neither Garro nor his wife could simply stand by the door waiting for it to show up, so he came up with a device（装置） made up of a minicomputer complete with a camera that would use motiondetection（运动检测） and imagerecognition AI software to
automatically identify the cat and then message him so he could let the animal in.
“We just want to be notified when he is around,” Arkaitz explained.“When it detects movement, it sends the picture to a recognition software, which checks against the identity of the cat based on previous imagery of the cat.”
“It took me just a few hours to put all the pieces together and the software up and running, but some more time after to fine tune the software to be able to recognize the cat,”
Arkaitz said, but in the end it proved to be effective.
24. What did Arkaitz Garro think of his invention?
A. It was moneysaving. B. It was ecofriendly. C. It was timeconsuming. D. It was easily made.
25. Why di d Arkaitz Garro and his wife put up some pictures of the cat?
A. To seek a shelter for it. B. To find its true owner.
C. To look for a potential buyer. D. To advertise its presence to its companions.
26. How does Arkaitz’s system check against his cat’s identity?
A. By matching its image. B. By identifying its smell. C. By measuring its size. D. By recognizing its voice.
27. What is the last step of Arkaitz’s system when it works?
A. Send a message. B. Send the picture.
C. Detect movement. D. Require identification.

Cameron is no ordinary dog, and not just because he was born on Valentine’s Day. To Maggie, a firstgrader at Burgundy Farm Country Day School, the dog who spends most days on campus is more like a friend. When Cameron is near, Maggie feels“really, really, happy,” she said.“I feel safe around him,” she added.“He’ll lie down and ask me to scratch his tummy,” she explained, because Cameron likes Maggie.
Cameron is one of a handful of dogs at Burgundy, a K8 private day school in Alexandria, Virginia. Dogs started showing up there when the head of school, Jeff Sindler, brought his clumsy Labrador, Luke, to the main office building where Sindler works. After Luke died, Sindler adopted Cameron and brought him to campus, too, where the dog Maggie described as “really cute” became a school favorite.
“They don’t care if you’re good at basketball, or a great reader, or popular,” Sindler said. “They just want to be loved — equal opportunity,” he added. Cameron and the other dogs on campus — always fastened with a rope and with their owner — go a long way toward improving students’ social and emotional wellbeing, he said. They reduce tension and ease anxiety, and inspire happy feelings from students.
“They bring out some superbasic and important emotions,” he said,“and are especially helpful for children and adults who struggle in social communication.” Children often came from challenging backgrounds: many lived in poverty, or had to travel through dangerous neighborhoods to get to school, or shared a toocrowded home. When these emotionally needy children met the dogs, they relaxed and were more prepared to learn.
Just as important,  dogs on school grounds set a posit ive,  welcoming  tone. They help preserve the school climate that is accepting, supportive and curious.“Dogs are one way to hold on to that,” Sindler said, adding that“schools should be fun and exciting, and dogs can be a big part of that.”
For Sindler, including  Cameron was all part of an effort to create a safe environment where learning could flourish.
28. What makes the dog Cameron really special?
A. His rare category. B. His particular birthmark.
C. His attractive appearance. D. His companionable nature.
29. How do dogs on campus improve students’ social and emotional wellbeing?
A. By playing fetch together fondly. B. By offering them comfort equally.
C. By playing basketball together freely. D. By walking a long way together happily.
30. What does the underlined word“that” in paragraph 5 refer to?
A. A positive tone. B. The school ground.
C. A welcoming attitude.D. The school atmosphere.
31. What’s the purpose of the passage?
A. To encourage schools to bring in more dogs.
B. To explain why dogs help students with learning.
C. To introduce a way to help students grow healthily. 
D. To explore the possibility to challenge nodog rules.

People who risk their lives to save strangers do so without deliberation, according to a Yaleled analysis of statements from more than 50 recognized civilian heroes published online Oct. 15 in the journal PLOS ONE.
“We wonder if people who act with extreme altruism（利他主义） do so without thinking, or if conscious selfcontrol is needed to override negative emotions like fear,” said David Rand, a Yale psychologist who authored the study with Ziv G. Epstein of Pomona College in Claremont, Calif.“Our analyses show that strongly, extreme altruists report acting first and thinking later.”
Rand, who studies human cooperation, got hundreds of participants to read 51 statements made by individuals who have received the Carnegie Hero Medal, given to civilians who risk their lives to save strangers. Participants  analyzed those statements for evidence of whether they acted intuitively or with deliberation. An analysis of text by computer did the same.
“What you don’t find in the statements is people who say,‘I thought it over and I decided it was the right thing to do,’” Rand said.
Instead, most responded like Christine Marty, a 21yearold college student who rescued a 69year old trapped in a car during a flashflood.
“I’m thankful I was able to act and not think about it,” Marty said in a statement.
The findings are consistent with Ra nd’s previous studies of cooperation in“economic games,” where participants choose whether or not to share resources. In these studies, subjects
forced to think carefully tend to be selfish while those using intuition（直觉） are more likely to be cooperative.
Rand cautions that intuitive responses are not necessarily genetically hardcoded. He believes people learn that helping others is often in their own longterm selfinterest and develop intuitive habits of cooperation, rather than possessing an inborn tendency preserved byevolution.
“The best evolutionary outcome is to be able to learn, adapting to whether you were born into a situation where it is typically good to cooperate or to be selfish,” he said.
32. What conclusion was drawn from David Rand’s study?
A. Heroes help without thinking. B. Heroes offer help on purpose.
C. Heroes have a better selfcontrol. D. Heroes think carefully before they act.
33. How did Rand conduct his study?
A. By analysing heroes’ life stories. B. By interviewing heroes on the spot.
C. By studying heroes’ opinions about their behaviors. D. By keeping track of heroes’ conscious selfcontrol.
34. What can we infer about Rand’s opinion on heroes’ behavior?
A. It is inborn. B. It is acquired.
C. It is wellplanned. D. It is halfborn and halfmade.
35. Which of the following can be the best title for the text?
A. How heroes stepped out of danger
B. How heroes help others out of trouble
C. Heroes don’t deliberate before they act
D. Heroes deserve the Carnegie Hero Medal

Ways to reduce plastic waste
Plastic is found in virtually everything these days. Your food is packaged in it. Your car, phone and computer are made from it.   36   . While most plastics  are advertised  as recyclable, the reality is that they’re“downcycled.”
Luckily, there are simple steps you can take to dramatically decrease the amount of plastic waste you produce.37
One of the easiest ways to keep plastic out of the landfill is to refuse plastic straws. Simply inform your waiter or waitress that you don’t need one, and make sure to state this clearly when ordering at a drivethru. Can’t stand giving up the convenience of straws?   38  . Restaurants are less likely to bring you a plastic one if they see that you’ve brought your own.
Use reusable produce bags
About one million plastic bags are used every minute. A single plastic bag can take 1,000 years to degrade. If you’re already bringing reusable bags to the grocery store, you’re on theright track. Purchase some reusable produce bags and help keep even more plastic out of the landfill. However, avoid those bags made from nylon or polyeste（聚酯纤维）.   39  .
Use matches
  40  if you need to light a candle, build a campfire or start a fire for any other reason.
These cheap plastic devices sit in landfills for years and have even been found in dead birds’ stomachs. If you can’t bear to part with your lighter, pick up a refillable metal one to help cut down on waste.
A. Say no to straws
B. Choose cotton ones instead
C. Don’t use plastic container
D. Choose matches over plastic lighters
E. Most restaurants will have no problem with it
F. And you might even chew on it daily in the form of gum
G. Purchase a reusable stainless steel or glass drinking straw

At his graduation ceremony, my younger brother Peter presented me with a rose. I was trying to look  41  , but I had just had a major disagreement with my friend.

With the girls walking away,
Peter  46  down and picked it up. The rose lay there in his  47  , for the taking.“For you, Maria.” I couldn’t help smiling. It was so   48  of him to know how to make things better.

“Son, look how dry that is,” said Dad,  53  a branch,“all in the inside there.”
Peter told Dad to give him  54  a few weeks and bent next to the bush,  55  his fingers over the dirt at its base. Then Peter launched a（n）   56  operation for it. Early in June a single blossom（花朵） turned red among green leaves. That was when I first  57  Peter had  a gift for flowers.
Now when Peter passed me that  58  , I felt all my troubles faded into the background.
