分析 拥有积极的对待老龄化,可以让你有一天更好的适应身体上的变化,并分析了拥有积极心态的重要作用.

解答 CBABB  BCAAB  CDCBD
50.C 考察动词.adapt to是固定短语,意思是适应.结合前句中adjust very well 可知,两个短语是一样的意思,上下文相呼应.
51.B 考察名词.在第一句里提到了aging 指老年化,所以此处the natural process of aging自然变老的过程.
52.A 考察副词.根据第一段的介绍可知,有积极的心态对我们很重要,意思是在黄金年龄有健康的外表可以成功预防一些残疾.
53.B 考察名词.根据下文,有的老年人经历更多的变化,有的甚至比年轻人功能还要好,所以此处variation是变化不同的意思,在老龄化进程中,会呈现不一样的变化.
54.B 考察动词短语.根据前句说基因构造可以解释,但是也只能解释百分之三十,account for解释.
55.B 考察动词短语.relate to动词短语,意思是和…有关系,和年龄有关系的大多数改变都是和饮食锻炼习惯有关.
56.C 考察名词.从alcohol and tobacco可以看出,consumption是名词,消耗.意思是抽烟喝酒.
57.A 考察形容词.active和文章中第一段的People with a positive attitude toward aging 中positive一样的意思,积极的,前后相呼应.
58.A 考察分词.根据57空前的by staying…可知,此处需要一个动名词形式来并列,通过维持健康的饮食我们可以保持健康的生活方式.
59.B 考察形容词.根据后句的听力的减少,健忘以及虚弱可知,前面的视力也应该是衰退,所以failing符合题意.
60.C 考察副词.根据前句Growing older does not always mean you see poorly可知,很多老年人相对来说视力很好.
61.D 考察名词.根据前句the single greatest contributor to vision loss可知,视力下降的最大因素在于暴露在紫外线下,所以 exposure to固定用法,意思是暴露在紫外线下.
62.C 考察动词.从前文 simply eating leafy greens and other foods rich in these protective nutrients可以减少视力的下降.
63.B 考察名词.有听力障碍的人字以后会带来isolation,意思是孤独,不与人交往,还有不安全感.根据句意communication交流,competition竞争,occupation职业,均不符合题干.
64.D 考察连接词.前句提到了These hair cells and their nerve endings can be damaged by infections,genetic diseases,or treatment with certain drugs影响人听力下降的原因有很多,如感染,基因突变等.接着提到最严重的是噪音,两句之间是转折的关系,所以填however.

点评 完型填空,解题时首先需通读全文,理顺题意,找出信息词,建立语言的整体感.这是做好完型填空题的关键.其次细读首尾,推测意图,文章的首句是全文的"窗口",尾句是文章的总结、结论或点睛之笔.这样,通过阅读首句和尾句,就可以了解背景知识,对于空格位置的词语进行大胆分析和判断,以便揣测作者的意图,理顺思路,为后面的答题做好铺垫. 最后在通读全文的基础上,根据全文大意,展开逻辑思维,瞻前顾后,分析这一空格处在句中的地位,前后的关系和它所起的作用,认真观察选项,仔细推敲,确定最佳答案.

1.Water runs downhill from mountaintops to streams to rivers to oceans.But downhill running isn't the only way that water moves.A new study measures how water travels from country to country for human consumption.This flow isn't the type we usually think about.These scientists looked at the water used to grow and make the products which get shipped from nation to nation as imports or exports.They call this a flow of"virtual water".
We typically think of water as the liquid that flows from a tap.However,nearly all---92percent---of the water used by people goes into growing crops,according to water researcher Arjen Hoekstra at the university to Twente in the Netherlands.He and his team recently studied the hidden travels of virtual water used in products made from things like crops and meats.These products are shipped around the world.
Virtue water is immense.For example,consider a sugary soft drink.Hoekstra and his team estimated that to produce one half-liter of the drink requires between 170and 310liters of water.Only a tiny amount of that-about 1percent-is the water actually used in the soda.The vast majority of the water-about 95%-is used to grow and process the ingredients(原料).Another 4percent goes into the packaging and labeling,said the scientists.In Hoekstra's calculation,when one country produces a half-liter of soda and sells it abroad,it exports as much virtual water as would make a large refrigerator full of water.
According to Heokstra's new report,dry countries like Israel and Kuwait,both in the Middle East,get the majority of their virtual water from other countries,through imported products.More surprisingly,a few wetter countries,like the Netherlands and the United Kingdom,also get the majority of their virtual water from other places.That means that most of the water used to grow or produce the products and food consumed in those countries came from other countries.
In the United States,most of the virtual water used comes from American sources; only about 20percent of the virtual water comes from outside national boundaries.In China,even less of the water associated with its products-about 10percent-comes from foreign countries.
Tracing the water trade,Hoekstra and his team turned up other surprising relationships.For instance,often a dry region sends virtual water to a wetter region.Dry areas in northern China,for example,send virtual water to the southern part of that country,which is wetter.
Title:Virtual water
General introduction●Water flows downhill,and also travels (66)worldwide by means of import-export trade.
●The water used in all the processes (67)involved in producing goods and food is called virtual water.
An example●Producing one half-liter of a sugary soft drink requires much water,(68)ranging from 170to 310liters.
●About 1percent of the water is used in the soda,while about 95percent is used for the (69)growth and processing of the ingredients.
●Another 4percent is used to (70)package and label the drink.
●The water used to produce and export a half-liter of soda could (71)fill a large refrigerator.
The(72)Content(s ) of Hoekstra's new report●Dry countries as well as some wet countries get most of their virtual water from foreign countries by (73)importing products.
●China and the U.S.get virtual water (74)mostly/mainly from their own sources.
●Dry regions surprisingly (75)tend to send virtual water to wetter regions.
2.It can be difficult to meet new people and make friends,especially when you move to a new city or find yourself out of your comfort zone.How will you deal with the situation?(36)E There are several ways that you can meet people that you might not have considered in the past.
★(37)A You probably have several acquaintances that you see on a daily basis or a weekly basis.If you get along well with certain people,you can see if this acquaintance would like to go out and do something socially with you.If you have common interests,you might suggest that the two of you do something together that involves your interest.
★Make an effort to accept invitations.Sometimes people that you know may be having a barbecue or other type of social gathering.Try to ensure that you are able to attend and then show up at the appointed time. (38)G If you meet people that you click with,you can make a plan to see them again in the future or you can invite your friends to your own event and ask them to extend the invitation to the friends that were at their gathering too.
★Go out,even when you don't feel like it.It turns out that when people invite someone to join them for dinner or a movie or something else,they really want to hang out with you. (39)F
(40)B But once you have used the same methods a few times you will know exactly what works and what does not.Don't give up,everyone is different and it just takes time to get to know people.

A.Expand on current relationships.
B.Trying to make new friends can be annoying at first.
C.Do you work with people that you get along well with?
D.But don't call them several times a day or even several times per week.
E.Be more social and you'll make your life more exciting and fulfilled.
F.If you tend to say"no"often,people will eventually stop asking you to go with them.
G.These types of gatherings often lead to meeting different people who are friends of friends.
19.Understanding the basic tips on growing grass will help you create a healthy and green lawn.If you plan the right variety at the right time and in the right place,you'll achieve success.
Autumn is the ideal growing season for the majority of grass varieties.Prepare the soil in this season as you do for any other plant.Based on the type of grass that you have chosen,the nutrient requirements may differ.For poor soil that is lack of essential plant nutrients,you can supply it with some organic fertilizer.
To grow grass successfully,make sure you select the correct variety that will adapt to the soil conditions of your area and to the growing location.You can choose the American shade grass variety or native grass varieties.
The sowing of grass can be done on bare soil or on an existing lawn.After sowing the grass seeds,cover them with a layer of top soil to quicken the germination (萌芽) process.In the first few weeks,you should irrigate the area every other day.Reduce the watering frequency after the grass has germinated.The addition of proper fertilizers at the right time is necessary for the healthy growth of grass.In the case of grass growing in shady environments,limit the use of fertilizers.
Weed control is another important tip for growing grass.The presence of weeds in grass growing areas leads to competition for water and nutrients,thus resulting in the poor growth of the planted grass.Hence,in order to avoid this condition,ensure that you remove the weeds regularly.
Lastly,one should also watch out for the presence of diseases and pests around the grass growing site in order to preserve the beauty of the lawn.
