4、Linking the Red Sea to the Indian Ocean，the blue waters of the Gulf of Aden near Somalia are one of the most important trading routes in the world．But they are also the most feared．

Pirates（海盗）whose targets are ships and their crew often show up there．On September 25，a Ukrainian ship carrying 30 tanks became another victim．

The pirates have reportedly killed one of the crewmen and are now surrounded by the US Navy．But they are still demanding $20 million for the release of the ship．

This year alone，more than 50 ships have been attacked，25 hijacked（劫持），and 14 are currently being held．

Of course this is nothing new el[her．Ever since there has been water and ships there have been pirates．The earliest documented history of pirates dates back to the 13th century in the Mediterranean Sea．Even the famous Roman emperor Julius Caesar was kidnapped（绑架）by pirates at one time．

Piracy reached its peak in the early 1700s, especially in the Caribbean and off the coast of Africa．In the mid-20th-century，most pirates were common thieves．They used hooks to steal on board commercial ships，and took all that they could find．These pirates were more likely to flee than fight if met by the crew.

However，nowadays piracy has become a multi-million dollar business attracting many in poor countries such as Somalia．“The pirates are well funded and have all the latest equipment，including satellite phones，”said a top UN representative in Somalia．

In Asia，however，a trend started where pirates didn't just want to kidnap the stuff, they also wanted to control the ship．They would kill the crewmembers or kidnap them for ransom（赎金）. After the recent kidnapping of Ukrainian ship，people are also worrying that tanks and arms on board would fall into hands of terrorists.

Last week the UN called a meeting from all affected countries to fight piracy. “The international community is determined to stop these pirates who are weakening efforts to bring peace to Somalia. This cannot and will not be allowed to continue,” a representative said.

3、Teachers and textbooks beware―your future could be under threat from a quickly developing and very smart technology．

University of California researchers led by Jacob White hill recently programmed teaching robots to react to facial expression．White hill's achievement marked a major step forward in the way people could one day learn by establishing facial expression recognition in robot teachers.

The teaching robots or，Intelligent Tutoring Systems（ITS）are computer systems that provide personalized instruction and feedback to students without human intervention．The facial expression recognition allows a computer to react according to expressions a user makes.

He said that the system was an important development in improving learning systems. “Classical I T S typically have a somewhat rigid architecture of ‘first I ask a question; then I wait for a response; then I talk some more；then 1 wait for another response.’ Facial expression recognition，l believe，will allow the feedback from student to teacher to happen while the robot teacher is talking．”White hill said．

Experts agree the latest developments in ITS open new possibilities for how people could learn．University of Memphis researcher, Dr Andrew Olney，who recently received a US $1.3 million grant to develop an ITS，said the key to future learning will be enabling interactive（交互的），one-on-one instruction．

“The technology can benefit these more advanced learning scenarios（方案），”he said．

Although robot teachers of varying abilities have existed for more than 30 years，ITS developments such as White hill's and Olney's are pushing beliefs that robots could soon be as effective as―if not more effective than human teachers．

“The ITS which have been developed are already better teachers than people who have no experience。”Olney said．
