A
When yu lk up int the sky at night, have yu ever felt that yur eyes are deceiving yu? It seems that stars are mving all the time.
Actually, there’s nthing wrng with yur eyes. This twinkle (闪烁的) effect is called scintillatin (闪烁现象). Scintillatin happens because f air mvement in the earth’s atmsphere (大气). Light is “bent (弯曲)” when it travels thrugh different parts f the earth atmsphere. As the air in the earth’s atmsphere is mving all the time, the light traveling thrugh the atmsphere makes the stars lk as if they are mving, t.
The same thing als happens t things n the grund. On a very ht and shiny day, if yu lk at the rad, yu will see that the image (影像) in the distance is nt clear and things mve slightly. Yu can als see the same effect if yu drp a rck int water. The rck appears a little unclear under the mving water.
This twinkling effect causes a lt f prblems fr astrnmers (天文学家), because they cannt bserve the stars clearly. S, a telescpe was needed in space s that the air mvements in the atmsphere culd be avided. It tk a lng time t build the space telescpe but finally in 1990, a huge space telescpe called the Hubble Space Telescpe was successfully sent int space. Since then, astrnmers have made many imprtant bservatins that have helped peple understand space better.

28．When a rck is drpped int the mving water, it appears a little unclear. Why?
A．Because the water is t light t lift the rck up.
B．Because the light is “bent” when traveling thrugh the water.
C．Because the water becmes dirty when the light travels thrugh it.
D．Because the rck becmes dirty when the light travels thrugh the water.
29．The underlined wrld “they” in Paragraph 4 refers t ________.
A．starsB．prblemsC．telescpesD．astrnmers
