According to a review of evidence in a medical journal, runners live three years 61 (long) than non-runners. You don’t have to run fast or for long 62 (see) the benefit. You may drink, smoke, be overweight and still reduce your risk of 63 (die) early by running.

While running regularly can’t make you live forever, the review says it 64 (be) more effective at lengthening life 65 walking, cycling or swimming. Two of the authors of the review also made a study published in 2014 66 showed a mere five to 10 minutes a day of running reduced the risk of heart disease and early deaths from all 67 (cause).

The best exercise is one that you enjoy and will do. But otherwise … it’s probably running. To avoid knee pain, you can run on soft surfaces, do exercises to 68 (strength) your leg muscles (肌肉), avoid hills and get good running shoes. Running is cheap, easy and it’s always 69 (energy). If you are time poor, you need run for only half the time to get the same benefits as other sports, so perhaps we should all give 70 a try.

【文章大意】 本文是一篇说明文。文章讲述了跑步的好处，它可以帮助人们延年益寿。 61. longer

【解析】考查动名词。你也许喝酒、吸烟或超重，但仍然通过跑步会减少早亡的风险。此处of是介词，其后用动名词。故填dying。 64.is

【解析】考查动词的时态和主谓一致。医学报告显示：跑步比散步、骑车和游泳更能有效地延长寿命。这里叙述的是一个事实，故用一般现在时，且主语是it，要用第三人称单数。故填is。 65.than

【解析】考查比较句型。跑步比散步、骑车和游泳更能有效地延长寿命。根据文章中的more effective可知此处填than。 66.that或which

【点睛】本文比较难的一个题是70题。短语give it a try不容易想出来。

give a try试试。Give sb sth； give sth to sb这些短语学生都很清楚。但give后加it或sth的形式，比较少见。高考复习要尽可能多的复习相关的短语，尤其是用的比较多，而课本中出现较少的短语。 2.【2018·全国卷I I】

A taste for meat is ___63___ (actual) behind the change: An important part of its corn is used to feed chickens, pigs, and cattle.

【文章大意】本文是一篇说明文。文中讲述了中国为保护环境在农作物种植上做了一些变化并得到了世界上的知名人士的认可。

10 / 20

61. has grown

【解析】考查时态。since加时间点，主句要用现在完成时。句意：2011年以来，中国种植的玉米比水稻多。故填has grown。 62. the

【解析】考查冠词。句意：玉米产量在过去25年里增长了近125%，而大米只增长了7%。故是特指在过去的25年里。故填the。 63. actually

【解析】考查副词。句意：对肉的需求实际上是这种变化的背后原因。句子结构完整，用副词修饰句子。故填actually。 64. to improve

【解析】考查非谓语动词。句意：为了改善水质政府鼓励农民种植玉米而不是大米。没有连词可以且谓语动词是encourages，故improve应该用非谓语动词。此处表示目的，故用不定式。故填to improve。 65. than

【解析】考查连词。句意：玉米比大米使用的水更少。根据关键词less可知，填比较连词。故填than。 66. pollution

【解析】考查词性转换。句意：这一转变减少了中国较大的湖泊和水库的污染，使人们的饮用水更加安全。has decreased后跟名词作宾语，故填pollution。 67. global

【解析】考查词性转换。句意：中国约占全球化肥总消费量的30%。fertilizer consumption是名词短语，故应该用形容词修饰。故填global。 68.started

【解析】考查谓语动词。句意：在2005年政府开始了一项土壤测试项目。本句是when引导的定语从句，由于时间是2005年，故用过去时。故填started。 69. that/which

【解析】考查定语从句关系词。根据空后的谓语动词gives可知，该空缺少主语，指代program并且引导后面的句子。指物用that/which，故填that或者which。 70. feeding

【解析】考查省略句。句意：中国在养活了中国人民的同时又保护了环境。这一做法为全世界的农业和粮食政策制定人提供了很有用的经验。空格处表示正在进行的动作，while后面省略掉了China is，省略句的原则：在时间状语从句、条件状语从句、让步状语从句中，如果从句的主语和主句的主语一致且含有be动

11 / 20

词时，那么可以把主语和be动词一块省略。故填feeding。

点睛：学会分析句子成分。The Chinese Ministry of Agriculture finds that between 2005 - when the government started a soil-testing program which /that gives specific fertilizer recommendations to farmers - and 2011，fertilizer use dropped by 7.7 million tons. 这句话中有两个定语从句。一个是关系副词when引导的定语从句，先行词是2005，the government是主语，a soil-testing program是宾语，故此空缺少谓语动词，我们可以看出时态是一般过去时。另一个是关系代词指代program引导的定语从句，先行词是program，gives是第三人称谓语动词，可以看出是考查关系词。代指物并作主语，关系词要用that/which。 3.【2018·全国卷III】

I'm not sure _____61_____ is more frightened, me or the female gorilla(大猩猩）that suddenly appears out of nowhere. I'm walking on a path in the forest in the Central African Republic.

【解析】考查宾语从句。句意：我不确定哪一个更害怕，我，还是突然出现的雌性大猩猩。此处为宾语从句，空格处表示选择，所以用which表示“哪一个” 62. the

【解析】考查冠词。此处为固定短语at the top of，此处表示以最大的肺活量喊叫。 63. loudest
