Today I visited San Francisco’s modern-art museum. I was there to see a new exhibit about spaceflight.1.I like to “visit” this particular painting every time I go to the museum not only because it evokes（唤起）strong feelings, but because I always find something new.
There's real pleasure to be found in revisiting a museum replaying a game or rewatching a movie. Some of that enjoyment comes from the feeling of familiarity of course.2..There’s always plenty more to see, hear, taste, smell, feel, of understand the second or third time around. But how do you discover the exciting new thing in the familiar?
One way is approaching whatever task is at hand by searching for the things that you didn't see in the first time around. First, recognize that everything is always changing.3.Second, remove judgment from the experience, if possible, and just observe what's new. For example, look for the ways in which a change in your neighborhood is interesting or exciting.
4.That could mean removing sugar, coffee, a certain kind of media from your life for a specified time. Once the break is over, that same thing will have more of its former interest or excitement.5.So is true that novelty is fun, but given enough of a break in between, repeated experiences regain that initial excitement.
A. Repeated experiences like this are valuable.
B. Visiting a new country brings fresh experience.
C. Coffee will never taste better if you quit it for a month.
D. But the piece of art that made me cry was a familiar one.
E. But it also comes from noticing new things in what is so familiar.
F. So the second experience is never exactly the same as the first one.
G. Another way is changing your routine and taking a break of some kind.
Like most people, you have probably lost count of the number of perfect-looking shoes you have thrown away simply because the rubber soles (橡胶鞋底) are broken. In addition to the expense, it is also harmful to our environment. Now, thanks to a revolutionary self-healing 3-D printed rubber material, broken shoe soles may be a thing of the past.
The magical polymer (聚合物) is developed by the researchers at the University of Southern California’s (USC) and the University of Connecticut (UConn) . The team, led by USC Assistant Professor Qiming Wang, created it through a process called photopolymerization, which uses light to solidify the liquid used to create 3-D printed plastic. The researchers found that adding the right amount of oxidant (氧化剂) to the liquid allowed the 3-D polymer to heal (愈合) without slowing down the hardening process.
“When we gradually increase the oxidant, the self - healing behavior becomes stronger, but the photopolymerization behavior becomes weaker,” explained Wang. “There is competition between these two behaviors.”
The team, who published the findings in the journal NPG Asia Materials on February 1st,2019, state that the repair time can be reduced by increasing the room temperature. “If you just put a broken shoe on a bench at room temperature, the rubber will heal itself in six to eight hours,” Wang said. “If you apply heat at maybe 60℃, that expedites the healing process to about two hours.”
Given the material s huge potential, it is not surprising to hear that Wang and his team have been approached by several shoe-making companies eager to be the first to use the technology, which is still in the early stages. Once perfected, the scientists also hope to apply the technique to hard plastics that can be used to create self-healing toys, electronics, vehicle parts, and, if Wang has his way, even tires.
1.How do the researchers make 3-D printed plastic self- heal?
A.By changing the amount of light used.
B.By raising the temperature at which it is used.
C.By increasing the hardening speed of the liquid.
D.By adding the proper amount of oxidant to the liquid.
2.What can be inferred from the text?
A.The creation of 3-D printed plastic doesn’t need light.
B.The surrounding temperature determines the speed of healing.
C.Many shoe making companies got the right to use the technology.
D.Throwing away broken shoe soles has been a thing of the past.
3.What does the underlined word “expedites” mean?
A.Strengthens. B.Delays. C.Accelerates. D.Worsens.
4.Which of the following can be the best title of the text?
A.Self - healing shoes may be in our future.
B.3-D printing technology makes a difference.
C.Self - healing technology will serve many fields.
D.A revolution of rubber soles has changed our life.
A few years ago, a doctor gave a wrong prescription to a 9-year-old boy because he had accidentally clicked the next medicine listed in the drop-down menu. Unfortunately, the boy died.
Dr. Gidi Stein heard the story and felt forced to do something. “It was like killing someone with a spelling error. He just clicked on the wrong button…Stein said. “One would have thought there’d be some kind of spell-checker to prevent these terrible things from happening. But apparently this is not the case.”
Several things were immediately obvious to the 54-year-old Stein, who had previously studied computer science. “If you look at this problem from a bird’s eye view, there were so many places down the line where this decision could have been stopped-from the physician to the pharmacy (药房) even to the mother. All of them had all the relevant information to have the judgment that this was just the wrong drug for the wrong patient. For Stein, it represented a systematic failure.
Stein compared this with credit cards. “If you use your credit card in the daily routine over time, a pattern emerges of how we use our cards : the grocery store, the gas station in our local town. If your credit card would appear tomorrow in Zimbabwe, it would be unusual. The credit card company would call you and say, “‘Hey, was that you?’”
But nothing like that existed in the field of prescription drugs. So Stein set up a company called MedAware. He came up with a machine learning outliner detection system. In other words, he trained the computers to realize if a doctor accidentally prescribed the wrong medicine.
The system is already used in hospitals and doctor5 s offices. To date, MedAware has used their technology to help nearly six million patients in the United States and Israel.
1.What caused the boy’s death?
A.The doctor’s carelessness. B.The doctor’s poor medical skill.
C.The failure of the computer. D.The incomplete health care system.
2.How did Dr. Gidi Stein react to the boy’s death?
A.He was annoyed and put the blame on the doctor only.
B.He was regretful and tried to prevent similar accidents happening.
C.He was embarrassed and mistook it as a systematic failure.
D.He was confused and detected the mistakes in prescriptions himself.
3.What does Stein want to tell us by mentioning credit cards?
A.Credit cards are available for doctors’ prescriptions.
B.Instructions in using credit cards are offered to users.
C.The boy might have been saved with the technology like credit cards.
D.MedAware’s technology will benefit the patients in Zimbabwe.
4.It can be concluded from the text that ________.
A.MedAware’s technology helps doctors choose right medicine
B.MedAware’s technology checks the prescriptions doctors make out
C.Medical industry worldwide has enjoyed MedAware’s technology
D.The boy? s mother was not to blame for his death during the accident
Kyle Cassidy and three other members of the Annenberg Running Group were stretching on the grounds of the University of Pennsylvania, waiting for a few latecomers. The Penn colleagues and other community members meet three days a week for a roughly 30-minute jog and an occasional lecture. That's right― during some runs, one of them delivers a talk. Topics range from the brain to Bitcoin.
But on this day last January, it would not be their normal run. The first clue that something was off was the man who sprinted past them. "Running at an amazing pace," Cassidy told Runner's World admiringly. Cassidy discovered why the sprinter was so fleet of foot when another man ran by, yelling, “Help! He took my phone and laptop!"
At that, the group did what running clubs do: They ran, trailing the suspect down the streets of Philadelphia until he ducked into a construction site. The runners split up. Cassidy ran around to the far side of the site to cut the thief off while the others wandered the neighborhood hoping he had dumped the loot （赃物）in a backyard.
No luck. So they decided to ask residents whether they'd seen the guy. When they knocked on the door of one row house, they were in for a surprise. Unknown to them, he had already emerged from the construction site—and was hiding behind a bush by that very house. As the owner opened the door, the suspect darted out from behind the bush ... and right into the arms of campus police, who'd joined the chase shortly behind the runners.
The members of this running group are not hard-core athletes. But they do understand the benefit of a little exercise. ''Running is typically a useless sport where you turn fat cells into heat," Cassidy told The Philadelphia Inquirer. "But occasionally it can be useful, and here was one of those opportunities."
1.Why do the group members gather together?
A.To do some stretching. B.To have a regular run.
C.To deliver a lecture. D.To cover some topics.
2.What does the underlined word "sprinted" in Paragraph 2 probably mean?
A.Dashed. B.Pushed.
C.Jumped. D.Escaped.
3.We can infer that the success of the chase is mainly due to____ .
A.the assistance of the runners B.the owner of the row house
C.the campus police on patrol D.the joint efforts of the people
4.Which of the following best describes Cassidy?
A.Athletic and generous. B.Courageous and ambitious.
C.Helpful and humorous. D.Thoughtful and demanding.
