Mass media are tools of communication.Mass media allow us to record and pass information rapidly to a large，scattered(分散的)audience.They extend our ability to talk to each other by helping us overcome barriers caused by time and space.

    There are various ways in which mass media make daily life easier for us.

    First,they inform and help us keep a watch on our world. They gather and pass on information we would be unlikely or unable to get on our own.

    Second，mass media help us to arrange our time and life.  What we talk about and what we think about are greatly influenced by the media.When people get together，they tend to talk about certain happenings in the newspapers or on TV.Because we are exposed(暴露)to different points of view through different kinds of media every day，we are able to evaluate(评价)all sides of a certain issue.

    Third,the media are used to persuade people. A good example is advertising through the media.Newspapers，magazines and TV are filled with all kinds of colorful，persuasive advertisements.Though many advertising may not say openly that they want you to buy a certain product，they describe their products in such a way that you may want to buy them.

    Fourth,the media also entertain.  All of the media make some efforts to entertain their audience.For instance，even though the newspaper is primarily a medium of information，it also contains entertainment features(特征)．Television，motion pictures，fiction books and some radio stations and magazines are devoted mainly to entertainment.It is estimated that in the future，the entertainment function of mass media will become even more important than it is now.

    Elizabeth Blackwell was born in England in 1821, and moved to New York City when she was ten years old. One day she decided that she wanted to become a doctor. That was nearly impossible for a woman in the middle of the nineteenth century. After writing many letters asking for admission(录取) to medical schools, she was finally accepted by a doctor in Philadelphia. She was so determined that she taught school and gave music lessons to get money for the cost of schooling.

    In 1849, after graduation from medical school, she decided to further her education in Paris. She wanted to be a surgeon(外科医师) , but a serious eye problem forced her to give up the idea.

    Upon returning to the United States, she found it difficult to start her own practice because she was a woman. By 1857 Elizabeth and her sister, also a doctor, along with another woman doctor, managed to open a new hospital, the first for women and children. Besides being the first woman physician and founding her own hospital , she also set up the first medical school for women.

    You get anxious if there's no wifi in the hotel or mobile phone signal up the mountain. You feel upset if your phone is getting low on power and you secretly worry things will go wrong at work if you're not there. All these can be called “always on” stress caused by smart phone addiction(上瘾).

    For some people, smart phones have freed them from the nine-to-five work. Flexible working has given them more autonomy (自主权) in their working lives and enabled them to spend more time with their friends and families. For many others, though, smart phones have become cruel masters in their pockets, never allowing them to turn them off and relax.

    Pittsburgh-based developer Kevin Holesh was worried about how much he was ignoring his family and friends in favor of his iPhone. So he developed an app — Moment — to monitor his usage. The app enables users to see how much time they're spending on the device(设备) and set up warnings if the usage limits are broken. “Moment's goal is to promote balance in your life,” his website explains. “Some time on your phone, some time off it enjoying your loving family and friends around you.”

    Dr. Christine Grant, an occupational psychologist at Coventry University, said, “The effects of this ‘always on' culture are that your mind is never resting, and you're not giving your body time to recover, so you're always stressed. And the more tired and stressed we get, the more mistakes we make. Physical and mental health can suffer.”

    And as the number of connected smart phones is increasing, so is the amount of data. This is leading to a sort of decision paralysis (瘫痪) and is creating more stress in the workplace because people have to receive a broader range of data and communications which are often difficult to manage. “It actually makes it more difficult to make decisions and many do less because they're controlled by it all and feel they can never escape the office,” said Dr. Christine Grant.

    A fire broke out immediately after the quake.The fire started in a chemist's shop and spread quickly.Then the Fire Department in Napier came to help,but they were at a loss to control the fire as a result of losing their water supply.However,the water supply in Hastings,was still usable,allowing them to fight back against the fire.

    The force of the earthquake destroyed many of the city's famous landmarks（地标）.Chunks of the coastline were thrown into the sea.Napier's Bluff Hill,a popular tourist spot,was completely destroyed and thrown into the waters below.

    Most of the major buildings in the city were completely destroyed.Roads and communications across the whole area were cut.People were afraid to enter their homes for days and found shelters at the local Motor Camp or on the beach.There were about 150 aftershocks（余震）in the 24 hours after the main shock.Over the next 2 weeks,there would be 525 such aftershocks.

    Parents complain that children outgrow their clothes so fast that it costs a fortune（￡12, 000 on average per year）, going through seven different sizes in the space of their first two years. There could now be a solution：a new high－tech fabric（织物）that expands as the wearer grows.

    Ryan Yasin, who is studying for a master's degree at the London Royal College of Art, came up with the idea after purchasing clothes for his newborn nephew, only to find the baby had outgrown them by the time they arrived. In addition to the expense Yasin was also concerned about the environmental influence. The process of making and distributing just l kilogram, or 2. 2 pounds, of new fabric results in an average of 23 kg, or 50 pounds of greenhouse gases. To make matters worse, the “fast fashion” trend worldwide has caused garment production to double since 2000, with more than half of the clothing ending up in landfills annually!

    To find a solution, Yasin used his previous experience designing satellites to invent a way to fold synthetic（合成的）material such that it stretches in all directions.

    The first design, a pair of tiny pants, not only fit his baby nephew, but also his 2－year-old niece! After spending a lot of time perfecting the process and testing the design, Yasin is now awaiting a patent for his design and seeking investors（投资者）to bring the clothing to market.

    For his new line of Petit Pli, the designer plans to produce outerwear that is both waterproof（防水的）and windproof. The clothing will be machine washable and fold small enough to fit in a jacket or pant pocket. Yasin plans to establish a take－back system so that worn－out Petit Pli clothing can be recycled into new fabric.

    The designer does not expect parents to dress their children only in his expandable clothing, particularly since the current designs use synthetic materials. But he plans to soon produce the wear in “a wider variety of garments” and hopes that Petit Pli will be able to have an “influence on over-consumption. ”We surely hope he succeeds!

    With about 100,000 sea animals being choked or injured by plastic every year, the danger produced by the billions of pieces of plastics in our oceans is well-known. However,    given that most of the micro-plastics measure less than 0.5mm, collecting them is a challenge.

    Now, some Dutch environmentalists have created a floating park to catch plastic waste before it reaches the open seas and breaks down. The large floating park is the result of a five-year effort of the Wageningen University and Research, WHIM Architecture, and etc. The team's leader said, "We began by developing a 'plastic fisher(渔船). Fitted with two folding arms with extension of several feet into the water, it uses a net to catch bottles, and any other garbage that floats past."

    The portable equipment took a year and a half to be perfect. It was then placed at the edge of the harbor to collect the urban garbage accumulated in the Meuse, a major European river, which rises in France and passes through Belgium and the Netherlands before it goes into the North Sea. Since Rotterdam's NieuweWaterweg canal links the river the North Sea, it's the ideal place to catch the "fresh" plastic waste before it disappears into the open waters and breaks down.

    The waste collected by the "plastic fisher" was then made into some hexagonal (六边的) floats which were connected to create the floating park. Some of the blocks are open to visitors, while others house various types of plants and even trees for nesting birds. The underside of the floats provides a suitable environment for sea creatures like fish. The environmentalists say the blocks can also be used to build sports areas and public walkways.

    The floating park has achieved great success. The team has launched a similar project in Indonesia to deal with local pollution. They worked with the local government and colleges which have given great support. And the team wants to spread their idea to some other places. When more and more people have better understanding of the project, more countries worldwide will know the advantages of the project and try similar outstanding approaches.
