1、Whether you own a small or large business, it's important that you apply technology to business. This calls for you to have high speed Internet in your business. You also need to have a very effective telephone line. The reason for this is due to the benefits that come with technology.
Communication is very important in business. The business world has become very competitive, thus employees need to communicate with clients fast and effectively. Communication is not only important when working with clients,but also important when working with other employees. For example, sales representatives and technicians don,t have to return to the office in order to know their next tasks. They can simply make phone calls or send emails. To make your business more modern, you should consider having a social media account.
Through technology,employees from different locations are able to interact(互动) and they not only talk about business,but also personal issues. This ensures that there is a healthy working environment, which plays a huge role in increasing the productivity of the employees.
IT experts have come up with many advanced software programs that allow your business to keep its records in an organized manner. The records can be on raw materials, suppliers,clients, and finances. These programs remove manual(手工的) record keeping, which not only aids in improving the working efficiency(工作效率), but also aids in removing human errors.
If you don’t have a large office space, you can ask your employees to work at home and send you the necessary documents via email. As a business manager, you don’t have to travel in order to hold a business meeting as you can do it over the Internet.
These are some of the benefits that come with technology. You should note that although technology is of great importance in the professional environments you need to manage it properly so that it’s not misused by employees.

2、Weather could power the next generation of smart windows. Researchers have created glass by harvesting energy from wind and precipitation(降水).The approach offers an alternative to other smart windows powered by batteries, solar panels, and even standard power outlets. “The creation represents a new kind of renewable energy source”, says Liming Dai, a nanomaterial engineer at Case Western Reserve University in Cleveland, Ohio, who was not involved in the research.
Smart glass, which changes its characteristics to block out light or heat, has been around for decades. Common examples include glare-fighting rearview(后视) car mirrors and windows that change color for en ergy savings and privacy. But many are expensive, and people are still looking for eco-friendly ways to power the

windows. Batteries and plug-in outlets aren’t apparently “green”,and built-in solar panels can cloud or hide parts of the glass.
In experiments, the glass produced up to 130 milliwatts per square meter, enough to power a pacemaker or a smart phone while it’s asleep,the team reported online last month in ACS Nano. This output might suit many applications,such as being a power source for home or office electronics, says co-developer and scientist Zhong Wang of the Georgia Institute of Technology in Atlanta Since their first project in 2012, a light-up sidewalk powered by footsteps, he and his colleagues have miniaturized their generators to create every thing from self-cleaning keyboards to sensors for security systems.
But Wang and colleagues still have more work to do before this smart glass is ready for commercialization. Now, the glass has no way to store the energy it creates. To solve this problem, Dai says, transparent supercapacitors(超级电容器) could be placed into the glass without decreasing visibility.
For now, the team wants to improve the energy efficiency of their nanogenerators. These tiny power plants can convert about 60% of the mechanical energy that they encounter into electricity. “The output power is a constant goal,” Wang says. “Free energy surrounds us, and anything can happen if you take control of it.\
1.What is unique about the smart glass? A.It can protect privacy. B.It is more expensive. C.It is powered by weather. D.It can block out light and heat. 2.What is the main idea of paragraph 3? A.The research history of Zhong Wang. B.The experimental process of Zhong Wang. C.The research theory of Zhong Wang’s team. D.The experimental findings of Zhong Wang's team. 3.What is the drawback of the smart glass?
3
A.It cannot suit the supercapacitors. B.It cannot keep its produced electricity. C.It cannot power a smart phone.
D.It cannot change its color according to weather.
4.Which of the following best explains “convert” underlined in the last paragraph? A.Transform. B.Consume. C.Waste. D.Reserve.
3、New App Helps People Remember Faces
Large gatherings such as weddings and conferences can be socially overwhelming. Pressure to learn people’s names only adds to the stress. A new facial-recognition app could come to the rescue, but privacy experts recommend proceeding with caution.
The app, called SocialRecall, connects names with faces via smartphone cameras and facial recognition, potentially avoiding the need for formal introductions. “It breaks down these social barriers we all have when meeting somebody,” says Barry Sandrew, who created the app and tested it at an event attended by about 1,000 people.
After receiving an invitation to download SocialRecall from an event organizer, the user is asked to take two selfies and sign in via social media. At the event, the app is active within a previously defined geographical area. When a user points his or her phone camera at an attendee’s face, the app identifies the individual, displays the person’s name, and links to his or her social media profile. To protect privacy, it recognizes only those who have agreed to participate. And the app's creators say it automatically deletes users’ data after an event.
Ann Cavoukian, a privacy expert who runs the Privacy by Design Center of Excellence praises the app’s creators for these protective measures. She cautions, however, that when people choose to share their personal information with the app, they should know that “there may be unintended consequences down the road with that information being used in another context that might come back to bite you.”
The start-up has also developed a version of the app for individuals who suffer
