Last weekend in Washington, D.C. 30 young researchers from across the nation were preparing for a competition. In a sense, all were winners already. After all, each had to beat out hundreds of others for the chance to arrive in the final. But only one competitor would take home the top prize: an educational award worth $25,000. Finally, Alaina Gassler, 14, won the top prize.
Alaina was one of the 30 finalists from 13 states who competed in the ninth yearly Broadcom MASTERS competition. Alaina and the other finalists had to be in sixth, seventh or eighth grade to attend the competition. What’s more, their research had to be judged within the top 10 percent of all projects. As usual, those projects all fell within the fields of science, technology, engineering or mathematics. Fifteen of the finalists took home major awards. For the first time this year, 60g% of the finalists were women.
Alaina developed a system whose goal is to improve driving safety. “Congratulations to Alaina, whose project has the possibility of reducing the number of traffic accidents,” said Maya Ajmera, president of Science and the Public, the organization that created the competition.
Alaina goes to school in West Grove, Pennsylvania. “I didn’t think I’d win an award this big.” she said. For her project, Alaina developed a system that could reduce blind spots for drivers. Such areas can hide objects or other cars from a driver’s view, and thus easily lead to accidents.
Alaina’s system depends on a camera fixed on the front part of the passenger-side window. It can monitor (监视) things a driver can’t see. The camera records a video of what it’s seeing and at the same time sends it to a projector (投影仪) fixed over the driver’s head. That projector plays the video on a screen, which is fixed on the passenger-side roof support. In this way, the blind spots are decreased.
1.What do we know about the competition?
A.It encourages teamwork. B.It is meant for college students.
C.It encourages theory exploration. D.It is a fierce national competition.
2.What is special about this year’s competition?
A.More winners stand out. B.More girls perform better.
C.All of the projects are more useful. D.Half of the competitors are awarded.
3.How does Alaina Gassler feel about her prize?
A.Surprised. B.Satisfied. C.Encouraged. D.Puzzled.
4.What plays the biggest role in Alaina Gassler’s system?
A.The projector. B.The monitor. C.The camera. D.The screen.

Public schools in Washington, D.C. provide students with musical instruments for free. When something goes wrong with an instrument, Charles West and Larry Jernigan do the repairs. Both men approach their work with a passion(激情). For them, it’s important that students have a joyful experience with music.
The two have worked together for almost 20 years. This year alone, they’ve fixed about 450 instruments. Both men are musicians and music lovers, so learning to do repairs came naturally.
“I have been a musician all my life.” says West. “I played in an orchestra here in the city. I majored in music in college. I played in an army band.”
Jernigan’s musical interests are varied. “I was formerly trained in the piano and guitar. The alto sax, and the flute, I picked up while working here.”
In addition to fixing instruments, the two also go to schools to instruct teachers and students on how to make minor repairs on their own.
West believes if children start early and stay concerned with music, it enriches other areas of their lives. “I see that in other kids. I see it in myself. I have seen it hundreds of times and it works,” he says. “They learn teamwork. They learn patience and respect.”
But West has concerns about the future of music in the electronic age.
“This instant age has taken away from the sit-down, the patience. And to learn to play an instrument, it takes patience, it takes diligence, it takes time.”
Being able to enjoy music on the job is one of the benefits of the job. Both men agree their best rewards are the students’ performances.
1.What’s the job of West and Jernigan at school?
A．Teaching music. B．Writing music.
C．Making musical instruments. D．Repairing musical instruments.
2.They love the job because they can ________.
A．earn more money B．learn repair skills
C．enjoy music D．watch performances
3.Which of the following is true of the two men?
A．They have fixed 450 instruments in the past 20 years.
B．They can play and repair musical instruments.
C．Jernigan used to play in an army band.
D．West was trained to play the piano.
4.According to West, what can people learn from music?
A．Teamwork and patience. B．The value of time.

5.What is mainly talked about in the text?
A．How to repair musical instruments.

Press your fingers into the back of your head, just above your neck. If you feel a small bony bump (突起), you may find evidence of human evolution (进化): it could be your body responding to common smartphone use in the 21st century.
According to a recent study, published in Scientific Reports, more young people have bony bumps at the base of their skulls, right above the neck. Medical professionals call them enlarged external occipital protuberances (EEOPs, 枕外隆突).
Australian health scientist David Shahar, the author of the study, told the BBC that he’s seen more and more patients with EEOPs over the past ten years. Together with other researchers from the University of the Sunshine Coast, Australia, they examined 1,200 skull x-rays from people aged 18–30. They also measured the bumps and noted each person’s posture. They found that one in four people had developed these growths. This led to their theory that smartphones are the cause.
According to their research, looking down at our phones adds stress onto the top of our spines (脊柱). To prevent damage to our spines, Shahar believes our bodies add fresh bony bump to help reduce the extra stress.
Most of the EEOPs measured just a few millimeters. However, several subjects were found with EEOPs as large as 30 mm.
In his report, Shahar said the results “highlighted the need” for prevention. In other words, we need to change our posture while using our phones.
Many people assume our bones are solid and unmoving once we reach adulthood. In reality, they are alive and covered with blood vessels(血管), which allows them to develop in unique ways for each person.
Aside from EEOPs, other noticeable recent changes in human bodies include shrinking jaws, narrower elbows and generally smaller skeletons. The human body is adapting to modern life, so who knows what people in the future might look like?
1.What did the recent study find about EEOPs?
A.They grow on one’s neck.
B.They can lead to many health problems.
C.They may stop growing when you reach 30.
D.They occur among more and more young people.
2.What is the main cause of EEOPs according to the researchers?
A.Extra stress. B.Aging bones.
C.Smartphone use. D.Gene problems.
3.Which of the following would Shahar probably agree with?
A.EEOPs increase the stress on our spines.
B.EEOPs are actually beneficial to our spines.
C.Young people’s bones adapt in similar ways.
D.Young people should exercise to improve their posture.
4.What’s the writing purpose of the text?
A.To persuade readers to protect their spines.
B.To explain why human bodies develop EEOPs.
C.To show some recent changes in human bodies.
D.To recommend some healthy habits of using phones.

Older adults with a better sense of smell may live longer than those who have a poor sense of smell, a new study suggests. The study was a project of researchers in the United States that was continuing for over 13 years. They asked nearly 2300 men and women to recognize 12 common smells. All the subjects were from 71 to 82 years of age. The researchers gave the adults marks, from 0 to 12, based on how many smells they recognize correctly.
During the years of follow-up research, over 1200 of the adults died. When the study was started, none of the adults were weak. They could walk about half a kilometre, climb 10 steps and independently complete daily activities. In the latest findings, the researchers noted those with a weak nose were 30% more likely to die than people with a good sense of smell. The findings were reported last month in the scientific publication Annals of Internal Medicine.
Honglei Chen, a doctor with Michigan State University in East Lansing, Michigan, was the lead author of the report on the study. He said the connection between a poor sense of smell and an increased risk of dying was limited to adults who first reported good or excellent health. This suggests that a poor sense of smell is an early and sensitive sign of worsening health before it is recognizable in medical tests. With a poor sense of smell, people are more likely to die of brain and heart diseases, but not of cancer or breathing problems.
The results also suggest that a poor sense of smell may be an early warning of poor health in older age that goes beyond dementia (痴呆) or other neurodegenerative (神经变性的) diseases. These often signal the beginning of the weakening of the mind or body.
1.What do we know about the study in the passage?
A.All the adults were in their eighties.
B.The adults were young and energetic.
C.The study lasted for more than 13 years.
D.The study involved international researchers.
2.What was the situation like at the beginning of the study?
A.Over 1200 of the adults passed away.
B.One third of the adults had a poor sense of smell.
C.Many of the adults were found with health problems.
D.All the adults could perform daily activities independently.
3.What can be inferred from the last two paragraphs?
A.People with a poor sense of smell have heart disease.
B.Most older people may have breathing-related disease.
C.People with a poor sense of smell won’t suffer from cancer.
D.Older people should be careful with their health if they smell poorly.
4.What is the meaning of the underlined word in Paragraph 1?

A murder will occur this weekend in the peaceful seaside town of Langley, Washington. In fact, a murder has occurred there every February for the past 25 years. But don’t panic! It’s all part of the town’s yearly Mystery Weekend.
What began as a local event in 1984 now attracts visitors from over the U.S. and even abroad. Would-be detectives（侦探）arrive and check in at the visitor center on Saturday. There, they receive a packet, including a newspaper with details about the crime and information telling where to find clues（线索）. Participants then travel to various shops, restaurants and other downtown locations, picking up clues as they go. Along the way, they encounter and interview suspects played by local townspeople. Most Langley residents participate in some way in the Mystery Weekend, a true community（社区）event.
Amateur detectives have until Sunday at 4:00 p.m. to solve the crime and turn in their guesses. Then as everyone gathers, the murderer is found and arrested, and prizes are awarded for correct answers. It’s the perfect ending for a murder mystery and enormous fun for those who get to play detective.
For visitors, Mystery Weekend is not only fun but also a great introduction to the charms of Langley.
