36. Cyberspace，of course，is bigger than a telephone call. It encompasses the millions of
personal computers connected by modems—via the telephone system—to commercial online services，as well as
the millions more with high-speed links to local area networks，office Email systems and the Internet. It includes
the rapidly expanding wireless services: microwave towers that carry great quantities of cellular phone and data
traffic；communications satellites strung like beads in geosynchronous orbit；low-flying satellites that will soon
crisscross the globe like angry bees，connecting folks too far-flung or too much on the go to be tethered by wires.
Someday even our television sets may be part of cyberspace，transformed into interactive “teleputers” by so-called
full-service networks like the ones several cable-TV companies (including Time Warner) are building along the
old cable lines，using fiber optics and high- speed switches.

(A)
MIT scientists have cooled a sodium gas to the lowest temperature ever recorded —only half-a-billionth of a
degree above absolute zero.

laureate Wolfgang Ketterle, co-leader of the team.

atomic clocks and sensors for gravity and rotation,
interferometry and co-leader of the MIT group.
The researchers also expect new phenomena to occur at such low temperatures involving, for example, how
cold atoms interact with surfaces and how atoms move when they are confined to a narrow channel or layer. These
gases form a remarkable state of matter called a quantum fluid, so studying their properties also provides new
insights into the basic physics of matter.
At absolute zero (-273 degrees C or -460 degrees F), all atomic motion comes to a standstill since the cooling
process has extracted all the particles' energy. By improving cooling methods, scientists have succeeded in getting
closer and closer to absolute zero. At room temperature, atoms move at the speed of a jet airplane. At the new
record-low temperature, atoms are a million times slower--it takes them half a minute to move one inch.
In 1995, a group at the University of Colorado at Boulder and an MIT group led by Ketterle cooled atomic
gases to below one microkelvin (one-millionth of a degree above absolute zero). In doing so they discovered a
new form of matter, the Bose-Einstein condensate, where the particles march in lockstep instead of flitting around
independently. The discovery of Bose-Einstein condensates was recognized with the 2001 Nobel Prize in physics,
which Ketterle shared with his Boulder colleagues Eric Cornell and Carl Wieman.
Since this breakthrough, many groups worldwide now routinely reach nanokelvin temperatures; the lowest
temperature reported before now was 3 nanokelvin. The new record set by the MIT group is 500 picokelvin, or six
times lower.
At such low temperatures, atoms cannot be kept in physical containers, because they would stick to the walls.
Furthermore, no known container can be cooled to such temperatures. Therefore, the atoms are surrounded by
magnets, which keep the gaseous cloud confined.
container, atoms are repelled by magnetic fields,
37. Which of the following do the researchers hope to know at the new record-low temperature?
( )
A. How to improve precision in measurement.
B. How to form a quantum fluid.
C. How atoms interact with each other.
D. How atoms move in a narrow channel.
38. In the ultra-low temperature gas, atoms move ________. ( )
A. as fast as a plane
B. as if running a mile under four minutes
C. at speed of half a minute
D. one inch for 30 seconds
39. The 2001 Nobel Prize in physics was attributed to ________. ( )
A. the efforts made by MIT scientists
