1、红色为重点 蓝色为次要 黑色为最次，但三篇都要求会背+第十五篇 “Liquefaction” Key to Much of Japanese Earthquake DamageThe massive subduction zone1 earthquake in Japan caused a significant level of soilliquefaction2 that has surprised researchers with its 1 severity, a new analysis shows.Weve seen localized3 examples of soil liqu

Entire structures were tilted and sinking into the sediments, Ashford said. The shifts in soil destroyed wate

We saw some places that sank as much as four feet.Some degree of soil liquefaction7 is common in almost any major earthquake. Its a phenomenon in which soils soaked with water, particularly recent s
4、ediments or sand, can lose much of their 4 and flow during an earthquake. This can allow structures to shift or sink or 5 . But most earthquakes are much 6 than the recent event in Japan, Ashford said. The length of the Japanese earthquake, as much as five minutes, may force researchers to reconside
5、r the extent of liquefaction damage possibly occurring in situations such as this8.With such a long-lasting earthquake, we saw 7 structures that might have been okay after 30 seconds just continued to sink and tilt as the shaking continued for several more minutes, he said. And it was clear that you
6、nger sediments, and especially areas built on 8 filled ground, are much more vulnerable.The data provided by analyzing the Japanese earthquake, researchers said, should make it possible to improve the understanding of this soil 9 and better prepare for it in the future. Ashford said it was critical
7、for the team to collect the information quickly, 10 damage was removed in the recovery efforts9.Theres no doubt that well learn things from what happened in Japan10 that11 will help us to reduce risks in other similar 11 , Ashford said. Future construction in some places may make more use of techniq
8、ues known to reduce liquefaction, such as better compaction to make soils dense, or use of reinforcing stone columns.Ashford pointed out that northern California have younger soils vulnerable to liquefaction -on the coast, near river deposits or in areas with filled ground. The young sediments, in g

In Oregon, for instance, that describes much of downtown Portland, the Portland International Airport and other cities.Anything 13 a river and old flood plains is a suspect12, and the Oregon Department of Transportation has already
10、 concluded that 1,100 bridges in the state are at risk from an earthquake. Fewer than 15 percent of them have been reinforced to 14 collapse. Japan has suffered tremendous losses in the March 11 earthquake, but Japanese construction 15 helped prevent many buildings from collapse -even as they tilted

12、由于大洋板块岩石密度较大，地位也低，便俯冲到大陆板块之下，这一俯冲部分叫做俯冲带。俯冲带两侧板块会聚边界称会聚边缘（convergent boundary)。俯冲带上面反映震源活动的地带称“贝尼奥夫地震带（Benioff seismic zone)。2. soil liquefaction：土壤液化。土壤液化现象是指由于孔隙水压力上升，有效应力减小所导致的土壤从固态到液态的变化，饱水的疏松的粉、细砂土在振动作用下突然破坏而呈现液态的现象。3. localized：小范围的4. geotechnical engineering：岩土工程。5. Oregon State University：俄勒
13、冈州立大学，建校于1858年，位于美国俄勒冈州科瓦利斯，全校设11个学院，80多个专业，尤以农科和工程最为突出。2008年俄勒冈州立大学的核能工程专业在全美大学中排名第9名。6. water, drain and gas pipelines：自来水管道、排水管道和煤气管道。water, drain and gaspipelines” 即“water pipelines, drain pipelines and gas pipelines。7. some degree of soil liquefaction：某种程度的土壤液化8. to reconsider the extent of liq
14、uefaction damage possibly occurring in situations such as this：本句的意思是：重新审视类似这次（持续时间长的）地震中因土壤液化而可能造成的毁坏的规模。9. recovery efforts：重建工作10. that well learn things from what happened in Japan：我们将从日本的地震中学到很多东西。该句是同位语从句，说出前半句no doubt的内容。11. that：that引导的是定语从句，修辞前半句中的things。12.suspect：被怀疑对象。文中指的是那些疑似危险的土壤。练习：1

17、. predict D. detect15.Astyles B. sites C. costs D. standards答案与题解：1.D前文说到日本的俯冲带地震是massive（巨大的），而且砂土液化到达一个significant level。根据上述描述，选widespread（分布广泛的）修饰severity是正确的。其他三个选项与severity搭配后，意思接不上。2.C 本句由but连接并列的两个分句组成。第一个分句说以前也发生过地震引发的砂土液化的现象，但涉及范围较小。第二个分句通过but语气一转，说这次地震造成的破坏是罕见的。很显然，选extent(程度)与distance（距离
18、，范围）合用说明破坏的程度和范围是符合上下文的意思的。3.A 在“The shifts in soil destroyed water, sewer and gas pipelines, crippling the utilities and infrastructure these communities need to”中，these communities need to.”是定语从句，指代utilities和infrastructure的关系代词which在定语从句中起宾语作用，被省略了。need后面的动词不定式的逻辑主语是which，也就是utilities and infrastr
19、ucture。从意思上看，这些社区需要这些公用事业设备和基础设施起功能作用（function)。选function是对的。其他选项都不合适。4.B 浸了水的砂土，特别是新近的沉积土、沙土等失去的不会是durability（耐用性）和ability（能力），也不会是泛泛的property（性质），而是strength（强度）。5.C 浸了水的砂土强度降低或消失。砂土随水流动，就会引发建筑物移位（shift）或下沉(sink)。再发展下去，建筑物就会倒塌（collapse)。collapse是答案。若选择ascend（上升）、compact(压实)或recover（复原），意思与上文接不上。6.A
20、 地震持续的时间一般为数十秒。这次日本地震的时间长达5分钟。所以本题要填入的词应该是shorter，说明大多数地震的持续时间比它短。7.C 从意思上看，选how是正确的。when structures、what structures或which structures意思明显不通。8.D 第三段第二句出现“particularly recent sediment。recent sediment浸水后就失去了强度。这提示了本题要选recently，因为建立在新近填就的土壤上的建筑物是最易受到伤害的。9.B 分析日本大地震得出的数据不会令科学家获得有关soil development（土壤发展）、s
21、oilformation（土壤形成）soil composition（土壤构成）这些方面的知识。若选phenomenon，意思就是科学家的研究分析有助于他们了解到土壤浸水后的这类现象，以便做好防备，对付未来可能发生的同类现象。上下文意思很连贯，因此phenomenon是正确的选项。1O.D 选unless、until或after都不合逻辑。本题句子的意思是：重建工作首先要清理废墟，这样地震现场就被破坏了。所以科学家要赶在重建工作开始之前收集好地震资料。before是答案。11.C 本句的意思是：科学家无疑会从日本大地震中学到不少东西，从而有助于减低今后发生类似的地震时的风险。四个选项中只有ev
22、ents合适。similar events指的是“类似的地震事件”。若选findings（调查结果）、locations（地点）或sources（来源），句子的意思就不对。12.B 本句解释“young”这个词在地质学中的含义。句中的those指代sediments。young sediments指那些年代少于或略超过一万年的sediments。deposit是“沉积”，与句子意思匹配，是答案。其他三个选项，词义离题很远，只是词形与deposit有点相似，起干扰作用而已，它们不是答案。13.A 上一段说，younger soils是非常脆弱的。本句的anything指的是soils。哪些地方的
23、soils是疑似高危对象呢？如果指soils from/inside/over river and old flood plains是不合常理的。正确的选择应该是near，靠近河流和原洪泛区的土壤才是危险地区。因此near是答案。14.A 加固危桥的目的是为了防止坍塌。选项prevent是答案。15.D 在3月11日的日本大地震中，震区的建筑物倾斜、下沉，但没有倒塌。建筑上的什么因素起到了防塌的作用呢？当然不会是construction styles（建筑风格）、construction sites（建筑工地）或construction facilities（建筑设备）。日本的construc
24、tion standards（建筑标准）才是防塌的关键因素。因此standards是答案。*Free Statins With Fast Food Could Neutralize Heart Risk Fast food outlets could provide statin drugs fret of l so that customers can reduce the heart disease dangers of fatty food, researchers at Imperial College London2 2 in a new study.

34、 C advantages D turns14 A buying B wearing C cleaning D changing15 A increasing B finding C lowering D taking答案与题解：1、B 本文介绍说，吃汉蜗包等快餐食品容易引发心脏病，而服用statin能降低心脏病发作的风险，一正一负正好抵消。statln价格便宜，文章建议陕餐店像免费供应调味品那样免费供 应statlnfree of charge是同定搭配，意为“免费”选择charge是对的。2、C 本题要选suggest，因为其他三个选项在意思上都不合适、此外，本句主句的谓语动词用了coul
35、d( provide)，委婉地含有“建议”的意思。所以suggest是个不一的选择二3、 B 与降低unhealthy “LDL” cholesterol搭配的一定是amount（量），而不可能是number （数字）、volume（体积）或product（乘积）4、D从上下文判断，要降低(lower)的当然是risk，lower frequency（降低频率）、lower treatment（降低治疗）或lower diagnosis（降低诊断）与上下文的意思都不匹配。5、B 本句表达的意思是：Dr Darrel Francis在他的论文中说，经过计算一粒stain降低心脏病发作的风险足以抵
36、消吃一个奶酪汉堡包和喝一杯奶昔所增加的患心脏病的风险一所以本题的答案是enough。6、 C 顾客不可能在快餐店里preparing cheeseburger或cooking cheeseburger，而buying cheeseburger不会增加心脏病风险：所以，只有eating cheeseburger才合乎上下文的意思。7、A 从上下文判断，被cut out（去除）的effects -定是unhealthy effects，所以，unhealthy effects是本题的答案。8、D 本句中的in terms of意为“就而言”，要与后半句“一正一负相互抵消”的意思相匹配，所以只能是“
37、就患心脏病的可能性而言”。possibiliry是答案。9、 A 本句的意思与第五题的意思相同，即statin降低心脏病发作的风险与快餐增加的心脏病的风险在程度(degree)上大致相当。如果选择其他三个选项，意思变成了，“尺寸 ( dimension)f、角度(angle)上或范围（range)上大致相当”，就说不通了。10、D 填词所在的句子的意思告诉我们，具有讽刺意味的一点是：顺客可以随心所欲地免费享用不健康的调味品。as one likes是固定用法，意为“随某人所愿，随某人所喜欢”。所以，like是答案。其余二个选项用在本句中都不合适。11、 B transported（运输）、pr
38、eserved（保存）或converted（转换）填于句子中，意思都不顺。只有填入provided（提供）符合句意。provided是答案。12.、C 到快餐店去就餐的人当然是customer。13、 A为了降低开车和吸烟的风险，人们被鼓励要采取一些安全措施。作者借此说明为了降低食用快餐的风险，我们也要采取措施。根据这层意思，选择measures是正确的。take measure的意思是采取措施”。其他三个选项都不合适：take care是“注意，小心”take advantage是“利用”，Lake turns是“轮流，依次”。14、 B本题很明显要选Wearing，因为上下文的意思是“系上
39、安全带”buying a seatbelt. cleaning a seatbelt 和I changing a seatbelt都与上下文的意思相去太远。15、 C通篇文章都在阐述Statin能降低患心脏病的风险.所以，lowering(降低)是答案。*Chicken Soup for the Soul：Comfort Food Fights Loneliness Mashed potatoes, macaroni and cheese, may be bad for your arteries 1 according to a study in Psychological Science,
