分析 本文讲述了手机对人类生活的影响．一半以上的中国人都拥有手机，他们一睁眼就拿起手机，一整天都不放下．人们聚会的时候玩手机，甚至很多人开车时也玩手机，
这就不开避免的导致了很多车祸，有些人甚至把手机看作比他们的生命还重要．手机正在影响我们面对面的交流，不可否认通过手机结交朋友不能像现实生活中交朋友那样有益处，从长远来讲，面对面的交谈会给我们带来更强的交际能力．

解答 61．parties；考查名词复数，根据句意"在聚会时，越来越多的人在玩手机"可知此处应该用名词的复数形式．
62．driving；考查非谓语动词，while doing表示"某一动作进行时另一动作正在发生"，根据句意"很多人在开车时玩手机"可知这里用driving．
63．themselves；考查反身代词，根据句意"手机比他们自己的生命还重要"可知这里应该用反身代词．
64．to send；考查动词短语，take risks to do是固定短语，意为"冒险去做某事"．
65．in；考查介词，in many ways意思是"在许多方面"．
66．is affecting； 考查动词的时态，根据上下文语境可知"手机正在影响我们面对面的交流"，所以这里用现在进行时．
67．which；考查定语从句，这里用关系代词which指代some people check or send text messages in the presence of a friend这个句子．
68．seriously；考查副词，这里用副词形式来作句子的状语．
69．the；考查冠词，the same 特指相同的．
70．stronger；考查形容词的比较级，much后面跟形容词时要用形容词的比较级形式．

6．Nowadays，the food we eat seems to have great effects on our health．Although science has made enormous steps in making food more fit to eat，it has，at the same time，made many foods unfit to eat．Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well，especially cancer of the colon．Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures．
That food is reated to illness is not a new discovery．In 1945，government researchers realized that nitrates，commonly used to preserve color in meats，and other food additives，caused cancer．Yet，these carcinogenic additives remain in our food，and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful．The additives which we eat are not all so direct．Farmers often give penicillin to beef and living animals，and because of this，penicillin has been found in the milk of treated cow．Sometimes similar drugs are given to animals not for medical purposes，but for financial reasons．The farmers are simply trying to fatten the animals in order to obtain a higher price on the market．Although the Food and Drug Administration（FDA）has tried repeatedly to control these procedures，the practices continue．

7．An accident in a bicycle race in the United States eight years ago alerted James Chang to the importance of sports medicine．One of his riding companions（25）was injured（injure） severely in the accident．
From then on，Chang，45，a Chinese-American who was born in Anhui province，began to launch business relating to physical safety and medical assistance，particularly in sport．So（26）whenhe took up marathon running two years ago he was shocked to see frequent injuries，many of them avoidable．
"I always heard people talking about people in marathons in China dying suddenly，"he says，adding that one reason why many of these deaths happen is（27）thatthere is a lot of ignorance in China about what marathon running involves．
Many amateur runners in China who are highly competitive get carried away and run at a pace that is far in excess of（28）whatthey can expect their body to take，and even ignore clear signals such as pain，Chang says．
As Chinese have placed more emphasis on leading healthy life-styles in recent years，marathon and other long-distance running（29）have become（become） a highly popular sport across the country quickly．
More than 50 China Athletic Association-sanctioned urban marathons were held in the country last year，and 39 races involving more than 750，000 runners were held the year before．However，long-distance running is a serious business that can exact a heavy physical toll on runners．
"Marathon carries（30）higher（high） risks of injury than other forms of sport，"Hou says，adding that the key to avoiding injury is to strengthen the body through regular exercise and to be aware of one's own physical condition．
Although some chronic injuries are hard（31）to avoid（avoid），even for highly experienced runners，cramp，fainting and shock can easily be prevent（32）ifrunners better understand the sport，he says．

13．It is sad but true that people die in earthquakes（61）fromfalling furniture and bricks．Earthquake（62）safety（safe） is very important and there is more to it（63）thanjust keeping buildings from falling down．So if your home is in an earthquake area，you should prepare carefully before the earthquake（64）comes（come）．
First，make sure you buy a house which is earthquake safe．All pipes should be fixed to the walls and all walls should be（65）especially （especial） thick and strong．Make sure the building has no（66）broken（break） windows and is well repaired．
Second，look at the objects in your house．Objects（67）like computers，televisions and lamps can be tied to tables or（68）stuck（stick） to them so they won't easily move around．The cupboards，（69）where many small things are stored，should have strong doors．Always remember，（70）better（good） safe than sorry．
2．Food，football and fashion-Milan has it a11．The city is perhaps most famous for its annual Milan Fashion Week and its world-class soccer teams AC Milan and Inter Milan．And May will see it host the six-month Milan Expo，the theme of which is food and nutrition．
Milan may not the first place tourists think of when they think of Italy．Rome is the most famous city in Italian history，Venice draws visitors who want to travel along its canals and Florence is popular with art lovers．Yet Milan can often be left off tourists'lists．But although some see Milan as the"ugly sister"of these cities，according to Lonely Planet，in 2015the city is"suddenly back in fashion in a big way"．
The Milan Expo will look at the future of food，trying to answer the question of how Earth's fast-growing population can be fed in the future．According to Lonely Planet website．"144countries will set up shop northwest of central Milan，forming a mini city-within-a-city"．
Milan's famous opera house，La Scala，normally closed in the summer，will also host daily performances during the expo，reported Fox News．
Not interested in opera？Don't worry．Visitors who prefer sports may want to visit the San Siro stadium，home of the soccer teams AC Milan and Inter Milan．Tile stadium is one of the most famous in Europe and has seen many important games over the years，both in Serie A and the European Champions League．
So even if all of its fashion and beautiful people can make Milan seem"soulless"，as Lonely Planet said．it still has"a serious sense of history and place"．Many people will be discovering it this year，and eating great food from all over the world to help solve world problems．Will you？

19．Recently，educators and parents become concerned about the poor performance of boys in school．The so-called"boy crisis"in education refers （61）to both their academic performance and their behavior．In both areas boys'results are much （62）worse（bad） than girls'．
USA data shows that the boys rank behind girls in almost all areas of schooling．They earn lower（63）grades（grade） overall in primary school and high school．They are behind girls in reading and writing，and 30percent of （64）them are in bottom quarter of standardized tests，（65）compared（compare） with 19percent of girls．
Although the causes of the"boy crisis"are not （66）fully（full） understood，some experts believed that the same-sex classrooms and schools may help solve the problem．The idea is （67）to remove（remove） some of the distractions（分心） caused by the opposite sex，in order to improve students'concentration and hopefully their grades．The first Chinese school to experiment with this idea （68）is（be） the Shanghai No.8Middle School，（69）which began"boys-only"classes in September，2012．Although it is too early to tell if the reform has made a difference，its supporters argue that the results are（70）promising（ promise）．
