EST 1 Part I Listening Comprehension Section 1, Conversation (10 minutes, 10 points) Section 2, Passages (10 minutes, 10 points) Part II: Cloze Test (10 minutes, 15 points) Scientists who study the Earths climate are convinced that volcano eruptions have a significant effect on general weather patterns. In fact, one of the many (36) which attempt to explain how an ice age begins holds that the (37) is a dramatic increase in volcanic eruptions. The volcanic explosions, besides causing local thunderstorms and lightning, inject great amounts of gas and (38)_into the stratosphere (同温层). At this (39)，the volcanic material spreads all the way around the Earth. This volcanic material (40) a certain amount of sunlight and (41) some back into space. The net result is to (42) the planets surface. For instance, 43 was perhaps the largest eruption occurred in 1883 when the Indonesia volcano Krakatoa exploded. The following year was (44) in Europe as the year without summer because the (45) was so cool and rainy. While there is (46) scientific agreement that volcanic eruption can lead to cooling, (47) of how this happens are not clear. As a result, scientists cannot (48) whether the volcanic activity which (49) past ice ages would result (50) sufficient cooling to cause a glacial period. Similarly, it is not possible for scientists to predict the climate effect of a future volcanic eruption with any confidence. 36. A. theories B. inventions C. judgments D. discoveries 37.
