[简答题]Cambridge psychologists and computer scientists have developed a mobile phone technology which can tell if a caller is happy, angry, bored or sad. The EmotionSence technology will enable psychologists to show links between moods, location and people. It uses speech-recognition software and phone sensors attached to standard smart phones to assess how people’s emotions are influenced by day-to-day factors. The sensors analyze voice samples and then place them into 5 emotional categories: happiness, sadness, fear, anger and a neutral category (such as boredom or passivity). Scientists then cross-reference these emotions against surroundings, the time of day and the caller’s relationship with the person they are speaking to. Results from a pilot scheme revealed that callers are happier at home, sadder at work and display more intense emotions in the evenings.

[单项选择]Invented by American computer scientists during the 1970s, the Internet has been embraced around the globe. During the network’s first three decades, most Internet traffic flowed through the United States. In many cases, data sent between two locations within a given country also passed through the United States.
Engineers who help run the Internet said that it would have been impossible for the United States to maintain its hegemony (统治权) over the long run because of the very nature of the Internet; it has no central point of control.
And now, the balance of power is shifting. Data is increasingly flowing around the United States, which may have intelligence--and conceivably military--consequences.
American intelligence officials have warned about this shift. "Because of the nature of global telecommunications, we are playing with a tremendous home-field advantage, and we need to exploit that edge," Michael V. Hayden, the director of the Central Intelligence Agenc
A. the Internet was invented by American scientists
B. most Internet traffic flowed through the United States
C. the internet has to be under the control of a central point
D. the United States shared their roads for Internet traffic with other countries

[简答题]

Thirty-five years after computer scientists at UCLA linked two bulky computers using a 15-foot gray cable, testing a new way for exchanging data over networks, what would ultimately become the Internet remains a work in progress.
University researchers are experimenting with ways to increase its capacity and speed. Programmers are trying to imbue Web pages with intelligence. And work is underway to re-engineer the net- work to reduce spam and security troubles.
(46) All the while threats loom: critics ware that commercial, legal and political pressures could hinder the types of innovations that made the Internet what it is today.
Stephen Crocker and Vinton Cerf were among the graduate students who joined UCLA professor Len Kleinrock in an engineering lab on Sept. 2, 1969, as bits of meaningless test data flowed silently between the two computers. By January, three other "nodes" joined the fledgling network.
