问题     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 the 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.


选项 A、few
B、little
C、much
D、no

答案B

解析 语义衔接题。从第二段第三句"有记载的最大的两次地震发生在中国和阿拉斯加,达到了里氏8.5级"可知既然最大的地震达到了8.5级,这说明震级越高,造成的损害也就越大。由此可以推出,里氏2级应该属于非常小的地震,从下一句中的One that measures 4.5 On the scale can cause slight damage (4.5级地震会造成轻微的损害)可以推出,里氏2级地震造成的损害应该很小,故本题选择little,用来修饰不可数名词damage,表示"微不足道"之意。few不能人选是因为few后要求用可数名词;much与little意思刚好相反,这与震级越低,损害越小不符,故排除;no属于绝对选项,我们无法确定是否里氏2级地震不会造成一点儿损害,因此不选no。
