Will online courses transform world of education?

Some may wonder what it feels like to attend a class at Stanford University. The recently popular MOOCs (Massive Open Online Courses) can satisfy this desire. But they are also most likely to change the situation of higher education. Only last month，both Peking University and Tsinghua University announced plans to start open online course on the edX platform，one of the world’s major providers of MOOCs，to explore this new form of online education.

Gaining momentum(势头)

“It’s not only a change of platforms from offline to online. It’s more about a reform of

teaching methods，even the whole education system，”said Chen Jining，president of Tsinghua University.

The potential of MOOCs to reform education has been obvious in the US ever since the immediate popularity of the course Artificial Intelligence，taught by Stanford University professor Sebastian Thrun, who later co-founded Udacity, a platform with 1.6 million enrolled(注册) students in 200 countries. According to Nature magazine，by June 2013，74 percent of universities in the US offered some type of online course. Lu Fang, vice-president of Fudan University，explains the appeal of MOOCs as a simple case of supply and demand：“The demand for high quality educational resources from both enrolled students and professionals is feeding the rise of MOOCs，in which classes usually taught by top teachers are available to everyone，”said Lu.

Too early to replace

With easy access and free of charge, MOOCs are said to have the potential to change the present education system. But there are barriers，because hardly any universities offer degree certificates, as college administrators point out, it’s difficult to confirm if students are foaming anything in MOOCs，reposed USA Today．

The Wall Street Journal also reposed that，presently，a typical MOOC student is likely to have

already graduated from college and is using the course to explore an interest or acquire professional

skills. Even so, an increasing number of undergraduates are signing up.

“What we are really establishing(创建)are educational pathways for people who want skills that are related to contemporary jobs，”Thrun told The Wall Street Journal．

PERTH—Search crews will send a submarine(潜航器)deep into the Indian Ocean on Monday for the first time to try to determine whether signals detected by sound-locating equipment are from the missing Malaysian plane's black boxes, the Australian head of the search said.

Angus Houst on said the crew on board the Ocean Shield will send the underwater vehicle sometime Monday evening. The Bluefin 21 submarine can create a sonar(声呐)map of the area to chartany wreckage(残骸)on the seafloor.

The move comes after crews picked up a series of underwater sounds over the past two weeks that were consistent with an aircraft's black boxes.

“We haven’t had a single detection in six days, and l guess it’s time to go under water,” said Houston.

“Analysis of the four signals has reduced the search area on the ocean floor. The experts have therefore determined that the Australian Defense Vessel Ocean Shield will stop searching with the Towed Pinger Locator(拖曳声波定位仪)later today and use the underwater vehicle Bluefin 21 as soon as possible," he said at a news conference in Perth.

But Houston warned the switch to the submarine will not automatically "result in the detection of the aircraft wreckage. It may not.”

He said the submarine will take 24 hours to do each task, including two hours to dive, 16 hours to search the bottom, then two more hours hack up and four hours to download data.

Recovering the plane's flight data and cockpit(飞行员座舱)voice recorders is necessary For investigators to try to figure out what happened to Flight 370, which disappeared on March 8.

Houston said the search using the submarine will be a slaw and painstaking process.

The submarine takes six times longer to cover the same area as the pinger locator,and will need about six weeks to two months to examine the present underwater zone. The signals are also coming from 4,500 meters (15,000 feet) below the surface, which is the deepest the submarine can dive.

1.The submarine will be sent deep into the Indian Ocean on Monday to _____ .

A. create a sonar trap of the area

All people need to sleep. Sleep is a necessary process that promotes proper body functioning and can improve the quality of your life. Not only is the quantity of sleep important, but also the quality of sleep.

Your bedroom should be shaped to your taste and allow you to sleep in a peaceful environment. One of the biggest mistakes people make in their sleep is to use their bedroom for activities other than sleep. If your bedroom also functions as a command station for your life and work, the likelihood of your sleeping being poor is rather high. Bedrooms should be designed, decorated and used for sleep mainly. TVs, computers and other things should not be in your bedroom if at all possible.

Establishing regular sleeping and waking times can help improve the quality of your sleep especially for those suffering from sleeplessness. Avoid hot food, caffeine, sugar and alcohol at least 4 to 6 hours before your sleep time. Develop a regular exercise program. Proper exercise and nutrition will help improve sleeping patterns. However, avoid exercising 2 hours before sleeping, since this may stimulate your body and make sleeping more difficult.

Establish a pre-bedtime rule that will help you focus on sleep. You can try deep thought，reading or deep breathing and relaxation. Your bedtime rule should be yours. Do not worry about it fitting into a specific category. Do what is best for you.

Things such as room temperature, noise and light levels and even your bed mattress(床垫) can have a lot of effect on the quality of sleep that you experience. Block out distracting noises and lights. You are in your bedroom to sleep and not be distracted by environmental interferences.
