11.The Pacific Ocean
The Pacific Ocean is the(61)largest (large) of the Earth's oceans,(62)covering(cover) about 46% of the Earth's water surface and 32% of its total surface area.It extends (63)fromthe Arctic in the north to the Antarctica in the south,surrounded by Asia and Australia in the west and the Americas in the east.The Pacific Ocean contains about 25,000 islands.The(64)majority(major) of them are found south of the equator.(65)Thewater near the equator is less salty than that found in the mid-latitudes (中纬度) for(66)abundant(abundance) equatorial precipitation (赤道降水) throughout the year.The surface circulation of Pacific waters is(67)generally(general) clockwise in the Northern Hemisphere and counter-clockwise in the Southern Hemisphere.The exploitation of the Pacific's mineral wealth is various,(68)which is influenced by the ocean's great depths.In shallow waters off the coasts of Australia and New Zealand,natural gas is produced,and pearls(69)are harvested(harvest) along the coasts of Australia,Japan and the Philippines.One more thing worth(70)mentioning(mention) is that the Pacific's greatest wealth is its fish.

分析 本文作者主要从以下几个方面介绍了地球上最大的海洋---太平洋:文中首先介绍了太平洋所占据的海洋面积以及地球表面积,它所覆盖的地域范围及其所处的地理位置;其次介绍了太平洋上岛屿的数量以及大多数岛屿所处的地理位置;赤道附近水域的特点以及太平洋水域表层环流的特点;最后介绍了对太平洋矿产资源的开发情况;由于受太平洋巨大的深度的影响,不同的国家所拥有的资源有所不同,如:在澳大利亚和新西兰沿海的浅水区,盛产天然气;在澳大利亚、日本和菲律宾沿海则可以收获珍珠;然而太平洋,最大的财富当属它的鱼类.

解答 答案:
61.largest     考查形容词的最高级    本句的意思是:太平洋是地球上最大的海洋;此处用在定冠词the之后,应使用形容词的最高级;故填largest
62.covering  考查现在分词    此处在句中作原因状语,动词cover与其逻辑主语构成主谓关系;故填现在分词covering
63.from       考查固定短语      固定短语from…to…"从…到…";本句话的意思是:它从北部的北极圈一直延伸至南部的南极洲;故填from
64.majority  考查名词以及词形转换   此处用在冠词the之后在句中作主语,指大多数的岛屿;故将形容词major转换为名词majority 
65.The         考查定冠词    此处特指赤道附近的水域;故填The 
66.abundant     考查名词以及词类转换    此处用来修饰名词precipitation;意为:丰富的赤道降水;故名词abundance转换为形容词abundant
67.generally    考查副词    此处在句中修饰形容词clockwise;故填副词generally
68.which         考查关系代词    根据句意以及空缺处之前的逗号可知,本句是非限定性的定语从句;由于此处的关系代词指代的是逗号之前的句子;故填which
69.are harvested    考查时态及语态    由于此处的主语pearls与及物动词harvest构成动宾关系;根据上下文使用了一般现在时可知,此处应使用一般现在时态的被动语态are harvested   
70.mentioning    考查动名词   由于此处用在动词worth之后,意为:值得干某事;故填动名词形式mentioning

点评 本题主要考查了各种语法在短文中的具体运用.做本题时,需要在正确理解短文的前提下,逐句分析句意以及所考查到的语法现象;因此在平时的学习中,应熟练掌握各种语法知识,其中包括词法,句法,各种时态语态以及虚拟语气等.

2.A chocolate printer that allows sweet lovers to create 3D desserts by themselves is to go on sale at a cost of 2,500 pounds.
The machine squirts (喷射) out chocolate and,via computer instructions,allows the user to build any shape they like out of the food.But makers Choc Edge have missed the Easter rush.Even so,they hope the printer will be snapped up by retailers (零售商) immediately they come to the market.Britain's biggest chocolatiers Thornton's have already said they are interested.Because of the high cost,however,few individuals are likely to buy one.But the device could one day allow people to design their own 3D objects after submitting their designs on a website.Dr Hao,founder of Choc Edge came up with a prototype (原型) last year and has only just perfected it so that it can now go on sale."We've improved and simplified the machine,so now it is really easy to use,"he told the BBC."You just need to melt some chocolate,fill a syringe (注射器) that is stored in the printer,and get creative printing of your chocolate."
3D printing is a technology where a three dimensional object is created by building up successive layers of material.The technology is already used in industry to produce plastic and metal products,but this is the first time the principles have been applied to chocolate.The research has presented many challenges.Chocolate is not an easy material to work with because it requires accurate heating and cooling cycles.Dr Hao said,"What makes this technology special is that users will be able to design and make their own products.From reproducing the shape of a child's favourite toy to a friend's face,the possibilities are endless.It could be developed to help consumers design many products from different materials,but we've started with chocolate as it is easily available,low cost and harmless.""There is also no wastage as any spoilage (损坏物) can be eaten."Dr Hao added,"Eventually we may see many mass-produced products replaced by unique designs created by the customer."
EPSRC chief executive Professor Dave Delpy said,"This is a good example of how creative research can be applied to create new manufacturing and retail ideas.By combining developments in engineering with the commercial potential of the digital economy We can see the new market prospect (前景)-creating new jobs and,in this case,the chocolate printer is called sweet business opportunities."
67.Which is the advantage of the chocolate printer?C
A.It is easily available,low cost and harmless.
B.It mainly produces children's favourite toys.
C.The user can build the shape they like via computer instructions.
D.The designs made by it are the same as many mass-produced products.
68.What can we conclude from the passage?B
A.The printer sold well during last Easter.
B.The technology of 3D printing promises a good future.
C.The printer was perfected and went on sale many years ago.
D.It's the first time that the technology has been used in industry.
69.Dave Delpy's attitude towards the chocolate printer isB.
A.doubtful              B.approval         C.negative         D.critical
70.We can conclude that this passage is aC.
A.science fiction       B.book review      C.news report         D.travel guide.

10.Doctors say anger can be an extremely damaging emotion,unless you learn how to deal with it.They warn that anger can lead to heart disease,stomach problems,headaches,emotional problems and possibly cancer.
(71)F Some people express anger openly in a calm reasonable way.Others burst with anger,scream and yell.But other people keep their anger inside.They can not or will not express it.This is called repressing anger.
For years many doctors think that repressing anger is more dangerous to a person's health than expressing it.They say that when a person is angry,the brain releases the same hormones (荷尔蒙).They speed the heart rate,raise blood pressure,or sugar into the blood,etc.(72)A
Some doctors say that both repressing and expressing anger can be dangerous.They believe that those who express anger violently may be more likely to develop heart disease,and they believe that those who keep anger inside may face a greater danger of high blood pressure.
(73)G They say the first step is to admit that you are angry and to recognize the real cause of the anger,then decide if the cause is serious enough to get angry about.If it is,they say,"(74)E Wait until your anger has cooled down and you are able to express yourself calmly and reasonably."
Doctors say that a good way to deal with anger is to find humor in the situation that has made you angry.(75)B

A.In general,the people feel excited and ready to act.
B.They say that laughter is much healthier than anger.
C.Expressing anger violently is more harmful than repressing it.
D.Anger may cause you a cancer.
E.Do not express your anger while you are angry.
F.Anger is a normal emotion that we all feel from time to time.
G.Doctors say the solution is to learn to deal with anger.
