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 (中緯度) 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 本文作者主要從以下幾個(gè)方面介紹了地球上最大的海洋---太平洋:文中首先介紹了太平洋所占據(jù)的海洋面積以及地球表面積,它所覆蓋的地域范圍及其所處的地理位置;其次介紹了太平洋上島嶼的數(shù)量以及大多數(shù)島嶼所處的地理位置;赤道附近水域的特點(diǎn)以及太平洋水域表層環(huán)流的特點(diǎn);最后介紹了對(duì)太平洋礦產(chǎn)資源的開發(fā)情況;由于受太平洋巨大的深度的影響,不同的國家所擁有的資源有所不同,如:在澳大利亞和新西蘭沿海的淺水區(qū),盛產(chǎn)天然氣;在澳大利亞、日本和菲律賓沿海則可以收獲珍珠;然而太平洋,最大的財(cái)富當(dāng)屬它的魚類.

解答 答案:
61.largest     考查形容詞的最高級(jí)    本句的意思是:太平洋是地球上最大的海洋;此處用在定冠詞the之后,應(yīng)使用形容詞的最高級(jí);故填largest
62.covering  考查現(xiàn)在分詞    此處在句中作原因狀語,動(dòng)詞cover與其邏輯主語構(gòu)成主謂關(guān)系;故填現(xiàn)在分詞covering
63.from       考查固定短語      固定短語from…to…"從…到…";本句話的意思是:它從北部的北極圈一直延伸至南部的南極洲;故填from
64.majority  考查名詞以及詞形轉(zhuǎn)換   此處用在冠詞the之后在句中作主語,指大多數(shù)的島嶼;故將形容詞major轉(zhuǎn)換為名詞majority 
65.The         考查定冠詞    此處特指赤道附近的水域;故填The 
66.a(chǎn)bundant     考查名詞以及詞類轉(zhuǎn)換    此處用來修飾名詞precipitation;意為:豐富的赤道降水;故名詞abundance轉(zhuǎn)換為形容詞abundant
67.generally    考查副詞    此處在句中修飾形容詞clockwise;故填副詞generally
68.which         考查關(guān)系代詞    根據(jù)句意以及空缺處之前的逗號(hào)可知,本句是非限定性的定語從句;由于此處的關(guān)系代詞指代的是逗號(hào)之前的句子;故填which
69.a(chǎn)re harvested    考查時(shí)態(tài)及語態(tài)    由于此處的主語pearls與及物動(dòng)詞harvest構(gòu)成動(dòng)賓關(guān)系;根據(jù)上下文使用了一般現(xiàn)在時(shí)可知,此處應(yīng)使用一般現(xiàn)在時(shí)態(tài)的被動(dòng)語態(tài)are harvested   
70.mentioning    考查動(dòng)名詞   由于此處用在動(dòng)詞worth之后,意為:值得干某事;故填動(dòng)名詞形式mentioning

點(diǎn)評(píng) 本題主要考查了各種語法在短文中的具體運(yùn)用.做本題時(shí),需要在正確理解短文的前提下,逐句分析句意以及所考查到的語法現(xiàn)象;因此在平時(shí)的學(xué)習(xí)中,應(yīng)熟練掌握各種語法知識(shí),其中包括詞法,句法,各種時(shí)態(tài)語態(tài)以及虛擬語氣等.

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 (噴射) 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 (損壞物) 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.a(chǎn)pproval         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 (荷爾蒙).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.
