21、Austrian company Tec-Innovation recently unveiled smart shoes that use ultrasonic sensors (声波传感器) to help people suffering from blindness or vision impairment (损伤) to detect obstacles (障碍物) up to four metres away.
Known as InnoMake, the smart shoe aims to become an alternative to the decades-old walking stick that millions of people around the world depend on to get around as safely as possible. The currently available model relies on sensors to detect obstacles and warns the wearer via vibration (振动) and an audible alarm sounded on a Bluetooth-linked smart phone. That sounds impressive enough, but the company is already working on a much more advanced version that includes cameras and artificial intelligence to not only detect obstacles but also their nature.
“Not only is the warning that I am facing an obstacle relevant, but also the information about what kind of obstacle I am facing. Because it makes a big difference whether it’s a wall, a car or a staircase,” Markus Raffer, one of the founders of Tec-Innovation, told TechXplore. “Ultrasonic sensors on the toe of the shoe detect obstacles up to four metres away. The wearer is then warned by vibration and/or audio signals. This works very well and is already a great help to me personally.”
The current version of the InnoMake shoe is already available for purchase on the Tec-Innovation website, for 3,200 per pair. The advanced system is integrated in the front of the shoes, in a waterproof and dustproof case. It is powered by a heavy-duty battery that can last for up to one week, depending on use. The battery can be charged in just three hours, using a USB cable.
The next step for Tec-Innovation is to use the data collected by its system to create a kind of street view navigation map for visually impaired people. “As it currently stands, only the wearer benefits in each case from the data the shoe collects as he or she walks. It would be much more sustainable if this data could also be made available to other people as a navigation aid,” computer scientist Friedrich Fraundorfer explained.
【1】What does the underlined word “unveiled” in paragraph 1 probably mean?
A．Purchased.
B．Launched.
C．Evaluated.
D．Promoted.
【2】What is required when a person uses InnoMake?
A．An ultrasonic sensor.
B．A walking stick.
C．A smart phone.
D．A new camera.
【3】What can we know about Markus Raffer?
A．He himself is visually impaired.
B．He is faced with a lot of obstacles.
C．He is the founder of TechXplore.
D．He has different opinions from others.
【4】Where does the text probably appear?
A．In a lab research.
B．In a book review.

22、Follow these tips to start a book drive in your neighborhood or school.
Before your book drive
Identify your volunteers. Recruit a committee of volunteers to assist you with planning and pick-ups on collection day.
Decide on the logistics (组织工作).
●Determine where to hold the book drive. Good locations include: small retail (零售) businesses or local schools.
You can ask businesses all over your area to collect books for the drive.
●Choose an appropriate time to hold the book drive. Join forces with an already-scheduled community event, or draw on a national celebration.
●At each collection location, ask for approval from management, and place boxes in a highly visible area.
●Determine what type of books you want to collect and what age group you are targeting. Your range can be as wide or narrow as you like.
●Determine the length of your book drive. A typical one lasts2-3 weeks.
●Select who is going to receive the books, and promote them in your other advertising efforts.
●Organize your materials. You’ll need boxes to distribute to businesses, storage space for the collected books and flyers (传单) to advertise your drive.
●Plan a kick-off event. Host a party, and ask each attendee to bring a book.
During your book drive
●Motivate. Organize a competition to encourage friends, neighbors, other parents, club members to donate. Keep track of which location and which individual contributes the most books. Recognize the donors with certificates or awards.

23、When to Start Growing Seeds(种子(Indoors for Your Garden
February marks the halfway point of winter in the northern part of the world. With spring arriving soon, many people are dreaming of working in their gardens on warm, sunny days. Some gardeners like to start the growing season early.【1】
It is important to know when to start growing your seeds indoors. The answer depends on where you live. Gardeners use the average last cold date in their area to help them know when to begin growing seeds.
After finding your start date, it is important to respect it. If you start too soon, plants likely will grow weak and struggle to do well. If you start too late, your harvest will be put off.
【2】You can use things like recycled yogurt(酸奶)or egg containers．Each container should have a hole in the bottom for water to flow through.
Fill each container with a clean, wet, soilless seed-starting mix.【3】It depends on the seed kind and size. Water the seeds as needed to keep the mix from drying out. Cover the seed containers tightly. Put them in a warm place out of direct sunlight.
When seedlings first appear, remove the covering and put containers by a sunny window. You can also put them under special lighting devices called grow lamps for 14 hours a day.【4】Costly lamps are not necessary.
If several seedlings come up in each container, cut the weakest at the soil line using small scissors(剪子)【5】 If you let more than one seedling remain, the roots may become mixed together. The young plants might not survive.
A．Ordinary lights will work.
B．Place one to four seeds in each container.
C．Put them in a warm place out of direct sunlight.
D．The aim is to keep only one strong-looking plant.
E．Leave them there for an hour and then bring them back inside.
F．They can do this by growing plants from seed inside their home.
G．While you are waiting, find and prepare your growing containers.

25、Last week, I taught a case study on the decline of Nokia to my MBA students. I asked them, “Why did Nokia fall from industry _________ to also-ran position in the space of less than five years?” Their answers were _________:
“They lost touch with their customers.” True, but almost tautological-and interesting to note that this is the same Nokia that in the early 2000s was praised for its _________-centric marketing and design capabilities.
“They _________ to develop the necessary technologies.” Not really true-Nokia had a prototype touch screen before the iPhone was launched, and its smartphones were _________ superior to anything Apple, Samsung, or Google had to offer during the late 1990s.
“They didn’t recognize that the basis of competition was shifting from the hardware to the ecosystem.” _________, not really true-the “ecosystem” battle began in the early 2000s, with Nokia joining forces with Ericsson, Motorola, and Psion to create Symbian as a _________ technology that would keep Microsoft at bay.
Through this period, the people at Nokia were _________ the changes going on around them, and they were never short of leading-edge technology or clever marketers. Where they struggled was in transmitting _________into action. The company lacked the capability to change in a decisive and committed way.
The failure of big companies to __________ to changing circumstances is one of the principal puzzles in the world of business. Occasionally, a genuinely “disruptive” technology, such as digital imaging, comes along and __________ an entire industry. But usually the sources of failure are more dull and avoidable—a failure to __________ technologies that have already been developed, an arrogant disregard(傲慢的漠视) for changing customer demands, a self-satisfied attitude towards new competitors.
In such cases, the final responsibility for __________ rests with the CEO. But if such failures are to be avoided, it is clear that the CEO cannot do it on his or her own. People across the firm must keep their eyes open to __________ in their business, and to take responsibility to push their new ideas and __________ existing ways of working. Obviously, this isn't easy to do, but if there is a better understanding of the problem then there is a chance for improvement.
