Electricity is the most common form of energy today. In the modern world electricity is very available at the touch of a switch. Electricity has many uses. The most common use of electricity is to provide artificial lighting. In factories, electricity is used to light up the workplace. It is also used to operate airconditioners, computers and many other machines. electricity is also used to power the many appliances that we have in our homes. Such appliances include television sets, computers, electric fans, irons and many others. The list is simply endless. Modern man will most probably be lost without electricity.

Tsunamis, whose name derives from the Japanese expression for "high wave in a harbor", are giant sea wave. These waves are quite different from storm surges. They are also referred to by the general public as tidal waves although they have nothing to do with tides. Scientists often refer to them as seismic sea waves, which is far more appropriate because they are often the result of undersea seismic activity.

Tsunamis can be caused when the sea floor suddenly moves, during an underwater earthquake or volcano, and the water above the moving earth is suddenly displaced. This sudden shift of water sets off a series of waves. These waves can travel great distances, at speeds close to 700 kilometres per hour. In the open ocean, tsunami waves are not very high, often no more than one or two metres. It is when they hit the shallow waters near the coast thay they increase in height, possibly up to 40 metres.

1. The passage mainly discusses __________

A. tidal waves B. tides C. tsunamis D. storm surges

2. All of the following is true about tidal waves EXCEPT __________

A. They are as another name for tsunamis

B. They are caused by sudden changes in high and low tides

C. this term is not used by the scientists

D. the name refer to the same phenomenon as seismic sea waves

3. The word "them" in the passage refers to __________

A. tidal waves B. tsunamis C. storm surges D. sea waves

4. The word "shallow" in the passage mostly means __________

A. not clear B. tidal C. coastal D. not deep

5. It can be understood from the passage that tsunamis __________

A. cause severe damage in the middle of the ocean

B. generally reach heights greater than 40 metres

C. are far more dangerous on the coast than in the open ocean

D. are often identified by ships on the ocean

          Quite different from storm surges are the giant sea waves called tsunamis, which derive their name from the Japanese expression for “high water in a harbor.” These waves are also referred to by the general public as tidal waves, although they have relatively little to do with tides. Scientists often referred to them as seismic sea waves, far more appropriate in that they do result from undersea seismic activity.

          Tsunamis are caused when the sea bottom suddenly moves, during an underwater earthquake or volcano for example, and the water above the moving earth is suddenly displaced. This sudden shift of water sets off a series of waves. These waves can travel great distances at speeds close to 700 kilometers per hour. In the open ocean, tsunamis have little noticeable amplitude, often no more than one or two meters. It is when they hit the shallow waters near the coast that they increase in height, possibly up to 40 meters.

          Tsunamis often occur in the Pacific because the Pacific is an area of heavy seismic activity. Two areas of the Pacific well accustomed to the threat of tsunamis are Japan and Hawaii. Because the seismic activity that causes tsunamis in Japan often occurs on the ocean bottom quite close to the islands, the tsunamis that hit Japan often come with little warning and can, therefore, prove disastrous. Most of the tsunamis that hit the Hawaiian Islands, however, originate thousands of miles away near the coast of Alaska, so these tsunamis have a much greater distance to travel and the inhabitants of Hawaii generally have time for warning of their imminent arrival.

          Tsunamis are certainly not limited to Japan and Hawaii. In 1755, Europe experienced a calamitous tsunami, when movement along the fault lines near the Azores caused a massive tsunami to sweep onto the Portuguese coast and flood the heavily populated area around Lisbon. The greatest tsunami on record occurred on the other side of the world in 1883 when the Krakatoa volcano underwent a massive explosion, sending waves more than 30 meters high onto nearby Indonesian islands; the tsunami from this volcano actually traveled around the world and was witnessed as far away as the English Channel

According to the passage, all of the following are true about tidal waves EXCEPT that________

A. they are caused by sudden changes in high and low tides

B. this terminology is not used by the scientific community

C. they are the same as tsunamis
