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、indulged in
B、taken in
C、interested in
D、involved in
答案D
解析 短语辨析题。本句中作者解释地震学家的概念，即那些参与这些工作的科学家是地震学家，"这些工作"就是上文提到的"开发早期预警系统来预测地震"。involve in意为"参与，涉及"，符合上下文语境。indulge in意为"纵容，沉迷于"，这个短语有"沉迷某事而无法自拔"的意思，而且此短语不用于被动语态；take in意为"包括，包含"，这个短语干扰性较强，take in主要表示"包含，涵盖"关系；interest in意为"对…感兴趣"，根据常识可以判断对地震学研究感兴趣的人不一定就是地震学家，可能只是该学科的爱好者而已。
