Can earthquake be predicted Scientists are (1) programs to predict where and when an earthquake will occur. They hope to (2) an early warning system that can be used to (3) earth-quakes so that lives can be saved. The scientists who are (4) this work is called seismologists. The word seismologist is (5) from the Greek word seismos, meaning earthquake.
Earthquakes are the most dangerous and (6) of all natural events. They occur in many parts of the world. Giant earthquakes have been (7) in Iran, China, India, Alaska, and so on. Two of the biggest earthquakes that were ever recorded (8) in China and Alaska, which measured about 8.5 on the Richter Scale. The Richter Scale was (9) by Charles Richter in 1935, and compares the energy (10) of earthquakes. An earthquake that measures a 2 on tile scale can be felt but causes (11) damage. One that measures 4.5 on the scale can cause slight damage, and an earth- quake that has a reading of over 7 can cause (12) damage. It is important to note that a reading of 4 indicates a quake ten times as strong as one with a reading of 3.
How do earthquakes occur Earthquakes are caused by the shifting of rocks along cracks, or faults, in the earth’s crust. The (13) is produced when rocks near each other are pulled (14) different directions.
Earthquake (15) is in its infancy. Scientists have only a (16) understanding of the physical (17) that cause earthquakes. Much more research has to be done. New and more up-to-date (18) have to be found for collecting earthquake data and analyzing it. (19) , seismologists have had some success in predicting earthquakes. Several small earthquakes were predicted. While this is a small start, it is (20) a beginning.

Jetlag
? ?Most people who
travel long distances complain of jetlag (喷气飞行时差反应). Jetlag makes business
travelers less productive and more prone {{U}}?(51) ?{{/U}} making
mistakes. It is actually caused by {{U}}?(52) ?{{/U}} of your "body clock"
-a small cluster of brain cells that controls the timing of biological
{{U}}?(53) ?{{/U}}. The body clock is designed for a regular rhythm of
daylight and darkness-ness, so that it is thrown out of balance when it
{{U}}?(54) ?{{/U}} daylight and darkness at the "wrong" times in a new
time zone. The symptoms of jetlag often persist for days {{U}}?(55)
?{{/U}} the internal body clock slowly adjusts to the new time
zone.
? ?Now a new anti-jetlag system is {{U}}?(56) ?{{/U}}
that is based on proven tentative pioneering scientific research. Dr. Martin
Moore Ede has {{U}}?(57) ?{{/U}} a practical strategy to adjust the body
clock much sooner to the new time zone {{U}}?(58) ?{{/U}} controlled
exposure to bright light. The time zone shift is easy to accomplish and
eliminates most of the discomfort of jetlag. A successful time zone shift
depends on knowing the exact times to either {{U}}?(59) ?{{/U}} or avoid
bright light. Exposure sure to light at the wrong time can actually make jetlag
worse. The proper schedule {{U}}?(60) ?{{/U}} light exposure depends a
great deal on {{U}}?(61) ?{{/U}} travel plans. Data on a specific flight
itinerary (旅行路线) and the individual’s sleep {{U}}?(62) ?{{/U}} are used to
produce a Trip Guide with instructions on exactly when to be exposed to bright
light. When the Trip Guide calls {{U}}?(63) ?{{/U}} bright light you
should spend time outdoors if possible. If it is dark outside, or the weather is
bad, {{U}}?(64) ?{{/U}} you are on an aero plane, you can use a special
light device to provide the necessary light {{U}}?(65) ?{{/U}} for a range
of activities such as reading, watching TV or
working. |
