One day, TunDe shared a story with Judy and her family. She remembered a particularly difficult day in 2014, when a stranger had helped her with a kind gesture. She had run out of gas, and with only$5 in her pocket ,was walking to a gas station, gas can in hand. A man saw her walking and turned his car around. He paid for her gas and gave her all the cash left in his wallet. Upon hearing the story , Judy’s son, Chris, took off his hat and said ,"That was me!” He was the stranger that had helped TunDe on that difficult day.
During the care of Judy, the Wright family learn ed about TunDe’s family and her own dream.
The nursing aid, TunDe hoped that one day she could become an OB-GYN nurse.Her tuition was past due（逾期） and she had a family to care for, but she was determined to achieve that goal for herself and her family.
Judy died on July 9,2017. Instead of flowers, her family asked mourners(悼念者） to donate to TunDe’s education , to assist her in paying for her nursing school. In less than a week, they raised more than $8,000 and presented her with the surprise check.

A study showed that the experiences children have in their first few years are important . These experiences affect the development of the brain. When children receive more attention, they often have higher IQs. Babies receive information when they see, hear and feel things, which makes connections between different parts of the brain. There are a hundred trillion(万亿）connections in the brain of a three-year-old child.
Researcher Judit Gervain tested how good newborns are at distinguishing different sound patterns. Her researchers produced images of the brains of babies as they heard different sound patterns. For example, one order was mu-ba-ba. This is the pattern"A-B-B". Another order was mu-ba-ge. This is the pattern “A-B-C”. The images showed that the part of the brain responsible for speech was more active during the" A-B-B"pattern. This shows that babies can tell the
difference between different patterns. They also were sensitive to where it occurred in the order.
Gervain is excited by these findings because the order of sounds is the building block of words and grammar."Position is key to language," she says. "If something is at the beginning or at the end, it makes a big difference:'John caught the bear.' is very different from 'The bear caught John.'”
Researchers led by scientist Patricia Kuhl have found that language delivered by televisions, audio books,the Internet, or smartphones－no matter how educational－doesn’t appear to be enough for children’s brain development. They carried out a study of nine-month-old American babies. They expected the first group w ho’d watched videos in Chinese to show the same kind of learning as the second group who were brought face-to-face with the same sounds. Instead they found a huge difference. The babies in the second group were able to distinguish between similar Chinese sounds as well as native listeners. But the other babies －regardless of whether they had watched the video or listened to the audio－learned nothing.
28. What makes connections in a baby’s brain?
A. Having a higher IQ.
B. Experiencing new information
C. The baby’ early age
D. The connection with other babies
29. What did Judit Gervain and her team find in the experiment?
A. Babies identify different sound patterns.
B. Word order is relevant to meaning.
C. Babies can well understand different words.
D. A certain brain region processes language.
30. What does the underlined sentence mean in Paragraph 3?
A. Grammar is important in learning languages.
B. Different orders have different meanings.
C. Different languages have different grammar.
D. Words have different sounds.
31. What is the main conclusion from the study led by Patricia Kuhl?
A. Babies shouldn’t watch a lot of television.
B. Listening to different languages develops babies’ brain
C. Foreign languages help babies’ brain develop
D. Social communication improves babies’ brain development.
D
On average ,Americans spend about 10 hours a day in front of a computer or other electronic devices and less than 30 minutes a day outdoors. That is a claim made by David Strayer, a professor of psychology at the University of Utah. In his 2017 TED Talk , Strayer explained that all this time spent with technology is making our brains tired.
Using an electronic device to answer emails, listen to the news and look at Facebook puts a lot of pressure on the front of the brain, which, Strayer explains , is important for critical (有判断力的）thinking , problem-solving and decision-making.
So, it is important to give the brain a rest. And being in naure , Strayer claims , helps get a tired brain away from too much technology. More than 15,000 campers from around the world attended an international camping festival in September. That is when friends and family take time off and escape to nature for several days. They take walks, climb, explore , swim, sleep, eat and play. Camping may be just what a tired brain needs.
Take Carl for example .He lives in West Virginia and enjoys camping . He says that staying outdoors makes him feel at ease. It also prepares him for the work he must do. Kate Somers is another example who also lives in West Virginia. She says she enjoys camping with her husband and two children . She calls it a “regenerative” experience.
At the University of Utah , David Strayer has studied both short-term and long-term exposure to nature. He found that spending short amounts of time in nature without technology does calm the brain and helps it to remember better. However ,he found , it is the long-term contact with nature that does the most good. He and his research team found that spending three days in nature without any technology is enough time for the brain to fully relax and reset itself.
32. What is David Strayer’s opinion ?
A. Americans dislike outdoor activities
B. Electronic equipment should be quitted
C. New technologies are a double-edged sword
D. Electronic equipment brings great convenience
33. Why does Strayer insist we go outdoors?
A. To try another lifestyle
B. To refresh our brain
C. To make better decisions.
D. To play with our family and friends
34. What does the underlined word “regenerative” mean?
A. Reborn
B. Memorable
C. Remarkable
D. Tiring
35. Which is the proper title for the passage?
A. Electronic Equipment Harms the Brain
B. Good Rest Develops Good Memory
C. Tips on Using New Technologies
D. Being in Nature Is Good for the Brain
