Earthquakes can rip apart entire cities and outlying districts, as the 1995 disaster in Kobe, Japan showed. SeismoLogists, scientists who study earthquakes and related phenomena, have records dating back to 1556, from the Chinese province of Shaanxi, which indicate that earthquakes have been devastating our world for centuries. The destructive forces which produce earthquakes usually begin deep below the ground, along a fault in weaker areas of the earth’s rocky outer shell, where sections of rock repeatedly slide past each other. As the fracture extends along the fault, blocks of rock on one side of the fault may drop down below the rock on the other side, move up and over the other side, or slide forward past the other. The violent shattering of rock releases energy that travels in waves, and these seismic waves move out from the focus of the earthquake in all directions. As the waves travel away from the focus, they grow gradually weaker, generally resulting in the ground shaking less as distances increase. Geological movements are not the only occurrences to trigger an earthquake. Human activity, most often the filling of reservoirs with extraordinarily large amounts of water, can also cause earthquakes. Similarly, massive explosions can wreak havoc, too. Earthquakes almost never kill people directly. Instead, many deaths and injuries result from falling objects and collapsing buildings, while fire resulting from broken gas or fallen power lines is another danger. The Kobe earthquake in January 1995 lasted only 20 seconds, yet resulted in a death toll of over 5,000 and injured approximately 26,000 people. Even though earthquake prone countries spend enormous human and financial resources on seismographic measurement, as a means of predicting earthquakes, there is a danger in paying too much heed to seemingly high risk zones and erecting less stable buildings solely because of their being in a low risk zone. Prior to the earthquake, Kobe was not regarded as at serious risk, but after the disaster, investigation of the damage revealed that nearly all deaths occurred in small buildings shattered rather than twisted when stressed. Coupled with the problem of soft soils, the buildings had little firm support and many crumbled. If countries wish to withstand the devastating forces of substantial earthquakes and reduce death, injury and property damage, it is important to design and construct buildings that are earthquake resistant, as well as monitor seismic forces. According to what is learned from the passage, which of the following will NOT lead to an earthquake
A. Nuclear tests.
Building tunnels.
C. Huge artificial lakes.
D. Bombardment with heavy missiles.

The cinema has learned a great deal from the theater about presentation. Gone are thedays when crowds were packed on wooden benches in tumble-down buildings to gape the 1. ______antics of silent, jerking figures on the screen, where some poor pianist made frantic efforts 2. ______to translate the dramas into music. These days it is quite easier to find a cinema that 3. ______surpasses a theater in luxury. Even in small villages, cinemas are spacious, well-lit and wellventilated places where one can sit for comfort. The projectionist has been trained to give 4. ______the audience time to prepare themselves for the film they are to see. Talk drops to a whisperand then fades out together. As soon ad the cinema is in darkness, spotlights are focused on 5. ______the curtains which are drawn slowly apart, often to the accompany of music, to reveal the 6. ______title of the film. Everything has carefully contrived so that the spectator will never actually 7. ______see the naked screen which will remind him all too sharply that what he is about to see isnothing merely shadows flickering on a white board.
