When I was four, my grandfather suddenly got lost in a park one day.It was the first instance that informed us that he had Alzheimer's disease (阿尔茨海默病)．Over the past 12 years, his worsening condition and his wandering have been worrying us.My aunt struggled to stay awake at night to watch over him, but often failed.Concerned about my aunt's well being and my grandfather's safety, I searched widely for a solution, but in vain.
Then two years ago, while looking after my grandfather, I was impressed by the moment when his foot landed on the floor.Why don't I put a pressure sensor on the bottom of his foot Once he stepped onto the floor and out of the bed, the pressure sensor would detect an increase in pressure caused by body weight and then wirelessly send an alarm to the caregiver's smartphone.My desire to create a sensor based technology was born.
When laying out my plan, I faced three main challenges.First, I had to create a wearable sensor.After testing different materials like rubber, which was too thick, I decided to print a film sensor with pressure sensitive ink particles (颗粒)．Next, I had to design a wearable wireless circuit.Thankfully, I was able to find out about the Bluetooth low energy technology, which produces little power and can be driven by a coin sized battery.Lastly, I learnt to code (编码) a smartphone app to turn the caregiver's smartphone into a remote monitor.
Integrating these components, I successfully created two models: a built in sock sensor and a re attachable one.Having tested it on my grandfather with 100% success in detecting his wandering, I beta tested it at California care facilities last summer.Now, I'm using response from tests to improve it into a marketable product.
One thing I'll never forget is when my device first caught my grandfather's wandering at night.At that moment, I was really struck by the power of technology to change lives for the better.

Researchers exploring the lightless landscape of the Pacific Ocean floor think they've observed how oxygen is produced on the Earth.
Until now, it was thought that oxygen was created only through photosynthesis (光合作用), a process that requires sunlight.But the discovery casts doubt on that idea and raises new questions about the origins of life itself.
The research team in Scotland, believe oxygen is being produced by electrically charged material called polymetallic nodules (多金属结核), which range in size from a small particle to about the dimensions of a potato.
These nodules — “effectively batteries in a rock，” Sweetman said — may use their electric charge to split seawater into hydrogen and oxygen in a process called seawater electrolysis (电解)．
Researchers conducted tests on the seafloor and also collected samples to test aboveground, and they came up with the same result: that oxygen levels increased near the polymetallic nodules.
Seawater can be split into hydrogen and oxygen with 1.5 volts (伏特) of electricity, which is the amount in an AA battery.Researchers found that some of the nodules possessed as much as 0.95 volts of electricity, and multiple nodules together produced enough voltages.
Polymetallic nodules contain metals such as manganese, nickel and cobalt, which can be used to make the lithium ion batteries used in consumer electronics, appliances and electric vehicles.
Franz Geiger, a Northwestern University chemistry professor, said that there may be enough polymetallic nodules in an area of the Pacific Ocean called the Clarion Clipperton Zone to meet global energy demands for decades after.But mining would have to be conducted in a way that did not remove oxygen for life forms in that zone.
“A few years ago, a team of marine (海洋) biologists went back to those areas mined 40 years ago and found essentially no life，” Geiger said.“And then a few hundred meters over to the left and right, where the nodules were untouched, plenty of life.”
8．Why is the discovery significant
A．It casts doubt on the existence of “dark oxygen”．
B．It shakes the view on the source of oxygen.
C．It shows the process of photosynthesis.
D．It displays the origin of life itself.
9．What enables seawater electrolysis in the deep sea
A．Photosynthesis. B．Sunlight reaching the seafloor.
C．Polymetallic nodules. D．Chemical reactions in seawater.
10．Why are the nodules in spotlights
A．To describe the mechanism in splitting seawater.
B．To demonstrate how powerful AA batteries are.
C．To stress the practicality of electricity generation.
D．To explain why more oxygen exists near the nodules.
11．What can we infer from Geiger's words
A．Marine ecology must be respected while mining nodules.
B．The Clarion Clipperton Zone has no life due to mining.
C．Marine biologists oppose mining in the ocean.
D．Mining nodules is beneficial for marine life.

We tend to think of large cities as melting pots — places where people from all sorts of backgrounds can associate and interact.But according to a new research, people in big cities tend to primarily interact with other individuals in the same socioeconomic level, while people in small cities and rural areas are much more likely to have diverse interactions.
A team of researchers led by Stanford University used GPS data collected from 9.6 million cellphones in the United States to determine how often people of different socioeconomic statuses crossed paths during the day.
After inferring each person's socioeconomic status from estimated rental prices on a housing marketing website, the researchers counted potential interactions between users over the course of the day — times where two cellphones had GPS pings (定位仪) within 50 meters of each other within a five minute window.They collected data on almost l．6 billion path crossings.The researchers found a clear pattern that has been missed by similar studies in the past: large cities contributed to socioeconomic segregation.
“That seems like an unexpected observation，” said Jure Leskovec, a professor of the team. “But there is a large variety of choices in big cities.In New York, you can spend D|S10 or D|S1,000 on a dinner, while if you live in a place with only one restaurant, everyone goes there, rich or poor.That seems to be the main mechanism for this phenomenon.”
The good news is, there are ways to build cities to have more socioeconomic mixing.Looking at large cities, the researchers found that those that placed frequently visited activity centres in between different neighborhood — instead of in the centre of each neighborhood — were less segregated.
“We've long emphasised residential integration, but we now have a new way，” said Grusky, a member of the research team.“When new shopping centres and other activity centres are up for approval, we need to make sure they're located in places that will promote diversity.”
12．What helps the researchers reach their conclusion
A．Studying people's interaction duration.
B．Assessing residents' living distances.
C．Surveying phone users in person.
D．Analysing GPS data from cellphones.
13．What does the underlined word “segregation” mean in paragraph 3
A．Integration. B．Development.
C．Division. D．Imbalance.
14．Why is “restaurant” mentioned in paragraph 4
A．To predict effects. B．To illustrate the finding.
C．To present a solution. D．To make comparisons.
15．What does Grusky propose to promote socioeconomic mixing in cities
A．Limit choices in large cities.
B．Increase the number of restaurants.
C．Enhance the taste of community activities.
D．Place activity centres in diversity rich areas.
