今年完形填空的难度较前两年略难,虽然话题不难理解,但不易把握上下文的线索。需要对文章内容有全面和精准的把握才能做好。主要内容讲的是虽然烤肉之类的食品是会对健康带来危害,我们对这些健康方面的危言耸听也不可过度恐慌。属于比较生活的话题。下面我们一起来看一下答案及解析。  
1.【答案】C  On  
【解析】此处考察介词词义辨析。On a cold winter's day意思是在一个寒冷冬日。介词on后加具体的某一天;in后加一段时间,例如in winter,in 2002;toward表方向,不与时间搭配;till意思是直到,例如till tomorrow,till next week,与句意不符。故正确答案为on。   
2.【答案】A  match 
【解析】此处考察动词词义辨析。文章的首段首句提到:即使家庭成员不太可能经常坐下来一起吃饭,但数百万英国人将在这个周末参加这个国家最伟大的传统活动之一:星期日烤肉。On a cold winter's day, few culinary pleasures can __2__it. 在一个寒冷的冬日,很少有什么乐趣与之匹配。match 匹配。express表达。satisfy满足,满意;确信;符合。influence影响。   
3.【答案】B  enjoyment 
【解析】此处考察上下文逻辑关系。上文说到星期日烤肉是一项开心的活动。后文Yet进行语义转折:然而正如现在报道的那样,食品卫生部门认为这种  3  会导致另一种有罪的快乐  4   损害我们的健康。enjoyment乐趣与上文pleasures和下文another pleasures互为关联信息。patience耐心,耐性。surprise惊喜。concern关心。   
4.【答案】D  guaranteed 
【解析】 此处考察非谓语动词做后置定语的用法。空格所在句指出:这种快乐会导致另一种有罪的快乐   4   损害我们的健康。 guaranteed有保证的,一定的,填入空格处意为:这种快乐会导致另一种有罪的快乐,肯定会损害我们的健康。 intensified增强,加剧;  privileged享有特权,专用,特许;compelled强迫。  
5.【答案】A  issued 
【解析】此处考察词义辨析。The Food Standards Authority (FSA) has __5__ a public warning... 食品标准管理局     一项公开的警告... issued发表,发布,发出;received接收,接到; ignored忽视,忽略;canceled取消。issued a public warning发出一项公开的警告符合文意。  
6.【答案】B  at 
【解析】此处考察介词辨析。in some foods cooked __6__ high temperatures. under在...下面;for为了;因为;对于; by在…旁边; 通过; 由于; 经过。   
7.【答案】D  avoid 
【解析】此处考察上下文逻辑关系。7空句首this mean代词this指代上文高温炙烤的食物里会有化学复合物有害人体身体健康。所以下文提出建议人们应该  7  炸土豆,不吃薄皮披萨并且...7空同时也与reject构成语义并列的关系,故avoid正确。forget忘记;regret 后悔;finish完成。 
 
8.【答案】A  partially 
【解析】此处考察词义辨析+上下文语境。...and only__8__ toast their bread.  8空前文说到建议人们不吃炸土豆,薄皮披萨或者只是   8  烤面包。partially部分地,偶尔地;regularly有规律地; easily 容易地;initially最初地。故A选项正确。      
9.【答案】D  While 
【解析】此处考察上下文逻辑关系+逻辑连接词辨析。 __9__ studies have shown that acrylamide can cause neurological damage in mice, there is no __10__ evidence that it causes cancer in humans.   9   研究表明丙烯酰胺可引起小鼠神经损伤,但是没有  10  证据表明它会导致人类患癌症。前后句为转折/对比/让步的逻辑关系,故选择while表示虽然,尽管。Unless除非,表条件的逻辑关系;Since因为,表因果逻辑;If如果,表条件的逻辑关系。   
10.【答案】C  conclusive 【解析】此处考察词义辨析+上下文语境。  9   研究表明丙烯酰胺可引起小鼠神经损伤,但是没有  10  证据表明它会导致人类患癌症。conclusive决定性的; 令人信服的; 确凿的 
secondary第二的,中等的;间接的;  external外面的,外部的; 表面上的; 外用的; 外国的; negative消极的,否认的。   
11.【答案】C  likely 
【解析】此处考察固定搭配。be likely to 可能。insufficient 不足的,不够的;bound捆绑的,束缚的,有义务的;slow缓慢的。  
12.【答案】A  On the basis of 
【解析】此处考察短语辨析+上下文逻辑。__12__ the precautionary principle, it could be argued that it is __13__ to follow the FSA advice.   12   预防性原则,可以说遵循FSA的建议是 13  。 On the basis of以...为基础,根据,按照;At the cost of以...为代价;In addition to除...之外; In contrast to与之相对,相反。  
13.【答案】B   advisable 
【解析】此处考察形容词词义辨析。 根据预防性原则,可以说遵循FSA的建议是 13  。interesting有趣的; advisable明智的,可取的; urgent急迫的; fortunate侥幸的,幸运的。  
14.【答案】D  After all 【解析】考察逻辑关系。原文中上一句说“基于“预防原则”,可以认为最好遵循FSA的建议”。本句说“在有证据证明吸烟与癌症之间的联系之前,吸烟导致癌症的传言就已经流传多年了。结合选项分析,As usual像往常一样,In particular尤其,特别,By definition根据定义,After all 毕竟,只有After all符合文意。  
15.【答案】C  connection 
【解析】本题考察动宾搭配,结合语境和句子成分理解,这里的名词放在prove“证明”后面,整体处在不定式中做主语补足语说明主语evidence,这里“证据”应该是证明出来(吸烟和肺癌)有联系的,故选择connection。Resemblance相似,combination结合,pattern模式,均不符合。  
16.【答案】B  served 
【解析】本题考察主谓搭配,此处为被动语态,和主语a piece of boiled beef 构成实际上的“动宾关系”,句意“毫无疑问,一片煮熟的牛肉总能在周日和一些蒸蔬菜一起__16__”。这里served up 表示“上菜,端上”正和文意。而其他选项made制作,saved节省,used使用,均不符合。 
  
17.【答案】A  To be fair 
【解析】本题考察主谓搭配,上一句说“但是生命值得过下去吗?”本句话说,“英FSA表示,它并没有告诉人们....不吃烘焙食品”,可见后文并没有对上文进行举例(for instance)或总结(To be brief)或表示经常发生的事情(in general),故,应该选择顺承关系的To be fair。  
18.【答案】B  entirely 
【解析】此处考察副词的修饰关系。本句话句意为“英FSA表示,它并没有告诉人们不吃烘焙食品__18__”。结合各选项分析:reluctantly不情愿地,entirely完全地,gradually逐渐地,carefully小心谨慎地,能跟前面的否定词not呼应使用表示一种部分否定的,只能是entirely才合适,not ...entirely表示“并未完全...”。  
19.【答案】C  campaign 
【解析】本题考察主谓搭配。根据原文语境“然而,他们(FSA)的...有风险给人一种‘劝诱式’保姆的感觉” ,答案campaign表示“(开展的)运动,活动”放在这里最合适。promise承诺,experience经历或经验,competition竞争,均不能体现本文中FSA所做行为的代称。  
20.【答案】D  end up 
【解析】考察动宾搭配,这里的句义是“持续不断的健康威胁__20__却没有人在听。”这里想强调太多的的对健康的恐慌的最终结果,只有“结束,以...告终”这个含义最符合,所以选择end up, 而follow up跟踪,坚持完成,pick up捡起,拾起,偶然学到,open up打开,开发,均不符合文义。
