SEATTLE (May 1 ) – Researchers at technology firm Nylobe, Inc., are working to develop a sensor capable of detecting corrosion caused by environmental exposure. Corrosion is a major contributor to ---143--- losses in the aircraft industry each year. "This will be a major ---144--- for commercial airline fleets," says Mel Laveau, Nylobe's CEO. "The sensor will decrease both labor and maintenance costs   without being too expensive."
According to Ms. Laveau, the sensor will work by detecting corrosion in its early stages, when the problem can be corrected simply by removing the corroded material. ---145---. In the structure of large aircraft, some critical joints can be particularly susceptible to corrosion. ---146---, the sensor can be used to inspect these areas and then target the most likely areas of concern.

From smartphones and tablets to apps and social media, society is ambushed from all sides with technology. Naturally, all generations embrace it differently, with younger “digital natives” generally being more connected, more switched-on and more tech literate than older age groups.
According to Pew Research, 92% of Millennials (born 1981–1996) own smartphones, compared with 85% of Gen Xers (born 1965–1980) and 67% of Baby Boomers (born 1946–1964). In terms of tech behavior, older generations tend to use their phones mostly for making calls, whereas for younger generations, a phone is their digital window to the world. Phones are used for social media, going online, texting, emailing, playing games, listening to music, and recording and watching videos.
The daily media consumption of different generations also vastly differs. Gen Z and Millennials favor streaming and online services, with 46% of teens saying they use Netflix compared to 31% of those aged over 16. Furthermore, 16-24s spend 30% of their downtime watching TV or video, compared to 40% of time spent on these activities by the average UK adult. Boomers spend a whopping 344 minutes a day watching regular TV, significantly more than any other age group.
Size also matters more depending on your decade of birth. Younger generations prefer smaller screens sizes, opting for a smartphone as their go-to tech, while Generation X and technology newbies - the Boomers, are going bigger, owning more desktops and tablets. Always in the front of the queue for the hottest tech, younger generations see technology as an integral part of their existence, and since few Millennials and Gen Z can remember a time without social media, they’re more fearless and carefree when it comes to technology. So much so, that a LivePerson report revealed 65% of Millennials and Gen Z interact more with each other online than they do in the real world.
Fundamentally, these behaviors and preferred technologies combine to create a technological generation gap, where employees, shaped by their personal experiences, demonstrate different levels of ability and willingness to adopt new tech. Constantly chasing the next update or device, switched on Millennials and Gen Z are quick to lap up the latest apps, games, and platforms, while Gen X and Boomers are generally slower to embrace technology - both at home and in the workplace.

According to paragraph 2, what is the technological characteristic of Millennials?

Recent technological advances in manned and unmanned vehicles, along with breakthroughs in satellite technology and computer equipment, have overcome some of the limitations of divers and diving equipment for scientists doing research on the great oceans of the world. Without a vehicle, divers often became sluggish, and their mental concentration was severely limited. Because undersea pressure affects their speech organs, communication among divers has always been difficult or impossible. But today, most oceanographers avoid the use of vulnerable human divers, preferring to reduce the risk to human life and make direct observations by means of instruments that are lowered into the ocean, from samples take from the water, or from photographs made by orbiting satellites. Direct observations of the ocean floor can be made not only by divers but also by deep-diving submarines in the water and even by the technology of sophisticated aerial photography from vantage points above the surface of more than seven miles and cruise at depths of fifteen thousand feet. In addition, radio-equipped buoys can be operated by remote control in order to transmit information back to land-based laboratories via satellite. Particularly important for ocean study are data about water temperature, currents, and weather. Satellite photographs can show the distribution of sea ice, oil slicks, and cloud formations over the ocean. Maps created from satellite pictures can represent the temperature and the color of the ocean's surface, enabling researchers to study the ocean currents from laboratories on dry land. Furthermore, computers help oceanographers to collect, organize, and analyze data from submarines and satellites. By creating a model of the ocean's movement and characteristics, scientists can predict the patterns and possible effects of the ocean on the environment.
Recently, many oceanographers have been relying more on satellites and computers than on research ships or even submarine vehicles because they can supply a greater range of information more quickly and more effectively. Some of humankind's most serious problems, especially those concerning energy and food, may be solved with the help of observations made possible by this new technology.

   My family consists of four people. There's my father whose name is Jan, my mother whose name is Marie, my brother, Peter and of course, me. I have quite a large extended family as well but, only the four of us live together in our apartment in a block of flats. My father is fifty-two years old. He works as an accountant in an insurance company. He is tall and slim, has got short brown and gray hair and blue eyes. My father likes gardening very much as well as listening to music and reading books about political science. His special hobbies are bird watching and travelling.

   Now I’ll describe my mother and my brother. My mother is forty-seven and she works as a nurse in a hospital. She is small, and slim, has short brown hair and green eyes. She likes bird watching and travelling too, so whenever my parents are able to they go someplace interesting for nature watching. Since we have a cottage with a garden they both spend a lot of time there. My brother is sixteen. He is slim and has short brown hair and blue eyes. He also attends high school. He is interested in computers and sports like football and hockey. He also spends a lot of time with his friends.

   I have only one grandmother left still living. She is in pretty good health even at the age of seventyeight so she still lives in her own flat. I enjoy spending time with her when I can. Both my grandfathers died from cancer because they were smokers, which was really a great tragedy because I didn't get chance to know them. My other grandmother died just a few years ago. I also have a lot of aunts, uncles, and cousins. The cousin I’m closest to is my uncle’s daughter Pauline. We have a lot in common because we are both eighteen and so we are good friends.

   My parents have assigned me certain duties around the house. I don't mind helping out because everyone in a family should contribute in some way. I help with the washing up, the vacuuming and the shopping. Of course I also have to help keep my room tidy as well. My brother is responsible for the dusting and mopping. He also has to clean his own room. Even though my brother and I sometimes fight about who has to do what job, we are still very close. I am also very close to my parents and I can rely on them to help me. My parents work together to keep our home well maintained and it seem they always have a project or another that they are working on. They respect each other's opinions and even if they disagree they can always come to a compromise. I hope in the future that 1 have a family like ours.
