Questions 7-12
 

Do the following statemets reflect the claims of the writer in Reading Passage 1?

In Boxes 7-12 on your answer sheet write
 

TRUE                      if the statemenht reflets the claims of the writer

FALSE                    if the statement contradicts the claims of the writer

NOT GIVEN           if it is possbile to say what the writer thinks about this

7  Inventors have long counted on the skies and the land rather than the sea to provide new ideas for their inventions.

8  Unlike submarine, fish uses the familiar human senses of sight and sound to build images of their surroundings.

9 The cells in the natural lateral1-line system can detect water movements which are not immediately noticeable.

10 Like any other shoaling fish, a small blind salman can still follow its mates without losing its way in water.

11 The most obvious application of the artificial lateral lines would be only in human-operated submarines in the future.

12 An artifical lateral-line system could detect the existence of the vortices caused by water passing even a motionless object.

Questions 13-14
 

Choose the appropriate letters A-D and write them in boxes 13-14 on your answe sheet.

13    According to the information in the text, which of the following statements describes the relationship between speed and amount of heat lost in Dr.Liu’s artificial lateral-line system?

A    When the water moved at a faster pace, it took longer time for the heated filaments3 to lose their heat.

B     If the water moved very slowly past a heated filament2, the filament would lose its heat fairly rapidly.

C    The speed of water moving past a heated filament was in direct proportion to the amount of heat it lost.

D     The speed of water moving past a heated filament was inversely4 proportional to the amount of heat it lost .

14    According to the information in the text, which of the following statements is NOT the charateristics of the natural lateral-line system in Dr.Liu’s tests on the artifical version of a fishy5 sense organ ?

A    The purppose of the first test was to investigate whether the system could locate the small pulsing movement caused by a vibrating ball.

B  The first test demonstrated that the pattern recorded from both the artificla lateral-line system and the nerve cells of a real fish was similar. 

C  The next test intended to explore whether the artificial system could identify the general direction of the source and the pattern of the vortices.

D  The second test showed that the vortices flew in the same direction on both sides of the sensors7, but with different pattern in the middle area.
