17、岩石有可能用力挤压另一块岩石，地壳的能量发生了改变导致岩石晃动，于是地震发生了。vibration意为“晃动”，故A选项正确。3C 细节理解题。由文章第二、三、四段中地震发生的时间顺序可知C项正确。4B 推理判断题。由第二段中“The greatest destruction came from the fires that followed the quake.”可知B项正确。BAngus,Doris,Gabriel and Kamil are some of the 21 names that have been chosen to be given to storms in the UK

18、 in the 2016/17 season.The Met Office,the UKs national weather service,decided to give storms boys and girls names in 2015 in the same way as they did in America.The Met Office hopes that naming big storms will mean people are more aware(意识到)of them and how dangerous they can be.Derrick Ryall,from t

19、he Met Office,said，“We have seen how naming storms elsewhere in the world raises peoples awareness of storms before they break.”In the past,the same UK storm could be given different names by different organisations.“We noticed that many organisationsduring the last couple of winters,when we have ha

20、d bad storms,started giving names to them.Think back to the St Judes Day storm in 2013,and the socalled Hurricane Bawbag in Scotland in 2011.But it led to confusion(混 乱)，”a Met Office spokeswoman said.According to the Met Office,there is a name for each letter of the whole alphabet(字母表),except for Q

21、，U，X，Y and Z.That is the same as the naming tradition used in America.And not all storms will be big enough to get names only those expected to cause great damage.If there are more than 21 storms in a year,the Met Office will start again with another name beginning with“A”.However,according to Met O

22、ffice spokeswoman Lindsay Mears，“Its unlikely we would get through the whole alphabet in one season.We had 14 storms in the very bad winter of 2013/14,and if the naming system had been in operation then we wouldnt have used the whole alphabet.”()5Why are storms in the UK named?ATo increase public aw

25、Mears?AThere are not too many big storms yearly.BAction will be taken to prevent storms.CThere are usually 14 storms in a year.DThe naming system will not change.CA答案及解析：【语篇解读】本文是说明文。文章主要介绍了英国为暴风雨命名的情况。5A 推理判断题。由第三段中的“naming big storms will mean people are more aware(意识到)of them and how dangerous th

26、ey can be”和“how naming storms elsewhere in the world raises peoples awareness of storms before they break”可推断，英国为暴风雨命名是为了增强人们对暴风雨的了解和防范意识。6B 推理判断题。本段的主题句是“In the past,the same UK storm could be given different names by differentorganisations”，下文通过举例说明该主题。7C 细节理解题。由倒数第二段中的“there is a name for each le

27、tter of the whole alphabet(字母表),except for Q,U,X,Y and Z”和最后一段中的“If there are more than 21 storms in a year”可知，在为暴风雨命名的时候，会以21个字母(字母表中一共26个字母，除了Q，U，X，Y，Z，还有21个)作为名字的开头。8A 推理判断题。由最后一段中Lindsay Mears所说的“Its unlikely we would get through the whole alphabet in one season.We had 14 storms in the very bad

28、winter of 2013/14”可推断，她认为英国每年不会发生那么多暴风雨。.七选五根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。The flood is one of the most common disasters in the US.Some floods develop slowly.But flash floods(山洪)can develop quickly,sometimes in just a few minutes and without any signs of rain.1_ It carries rocks and mud an
