12．Why is pink or purple a color for girls and blue or brown for boys？
The answer depends largely on cultural values as well as personal experiences．To the Egyptians，green is a color that represents the hope and joy of spring，while for Muslims，it means heaven．Red is a symbol of good luck in many cultures．In China，children are given money in a red envelope to bring good fortune in the New Year．For many nations，blue is a symbol of protection and religious beliefs．Greek people often wear a blue necklace hoping to protect themselves against evils（災(zāi)禍）．
People's choice of colors is also influenced by their bodies'reactions （反應(yīng)）toward them．Green is said to be the most restful color．It has the ability to reduce pain and relax people both mentally and physically．People who work in green environment have been found to have fewer stomach aches．

Blue is another calming color．Unlike red，blue can cause people to lose appetite．So if you want to eat less，some suggest that eating from blue plates can help．

分析 本文是一篇說明文，文章主要講述的就是在不同的文化中各種顏色的不同含義以及各種顏色的功能和作用．人們對顏色的喜好取決于文化信仰和個人的經(jīng)歷．人們對顏色的選擇受他們身體反應(yīng)的影響．紅色是暖色系，它會使人的血壓上升，增強人的食欲，易吸引人的眼球．而藍(lán)色則讓人容易鎮(zhèn)定，降低食欲．顏色與裝飾有很多關(guān)系．

解答 CABD
55．C 細(xì)節(jié)題．根據(jù)文章第二段  The answer depends largely on cultural values as wellas personal experiences．To the Egyptians，green was a color that representedthe hope and joy of spring，while for Muslims，it means heaven本段所舉的例子中對于顏色的選擇都是與文化價值觀或者個人經(jīng)歷有關(guān)的．穆斯林對于綠色的固定也是文化的影響．故C正確．
56．A 細(xì)節(jié)題．根據(jù)第四段2，3行Similarly，many commercial websites will have a red"Buy Now"button because red is acolor that easily catches a person's eye．說明用紅色是為了吸引人們的注意，鼓勵人們購買．故A正確．
57．B 推理題．根據(jù)倒數(shù)第二段blue can cause people to lose appetite．So if you want to eatless，some suggest that eating from blue plates can help．說明藍(lán)色可以讓人減少食欲，那么可以讓人減肥，故B正確．
58．D 主旨大意題．文章主要講述的就是在不同的文化中各種顏色的不同含義以及各種顏色的功能和作用．故D正確．

點評 做閱讀時經(jīng)常犯錯的主要原因是，僅憑讀過文章后殘留在腦海中的一絲印象來勾選答案，這樣便很容易掉入出題人故意設(shè)布下的題目陷阱．所謂閱讀理解，對于題目的理解一定要忠實于原文，因此，每一道題都應(yīng)該與原文作全面的對比與核查，再得出答案．也就是說，閱讀理解的每一道題目，在原文都應(yīng)該有明確的出處，我們把這一出處叫做原文相關(guān)句，（1）排除與原文相關(guān)句主題不一致的選項（2）排除與原文相關(guān)句態(tài)度相反的選項  （3）排除用于過于極端或負(fù)面的選項（4）注意結(jié)合文章主旨和主題去排除．

Past and present
Ginger-he key part of gingerbread and the houses themselves-has a long history．It is believed that ginger was used as early as 2，000 B．C．in China．Gingerbread houses were first written about during the 15th century．But it was the 19'th century fairy tale"Hansel and Gretel"that started the trend．As European immigrants made their way around the world，so did gingerbread houses!
One example occurred in the town of Belleville in the 1850s．As large numbers of German immigrants moved there，many brought along their gingerbread house recipes．Today，during the holidays，Belleville hosts a"Gingerbread Walk"through its downtown area．Along the path，shop owners display beautifully-made gingerbread houses and other gingerbread creations．The event allows visitors and locals alike to enjoy Belleville's tastiest tradition．
The world's largest
In 2006，Roger Pelcher constructed the world's largest gingerbread house in Bloomington，Minn．Measuring over 60 feet tall，the house took Pelcher's team l，700 hours to complete．To achieve the world record，Guinness World Records said 95 percent of the outside had to be eatable．So Pelcher used 14，250 pounds of gingerbread and over a ton of candy on the house!
Winning houses
At Christmas time，people from Sweden to Seattle enter their creations in gingerbread house contests．Winners receive prizes for the most difficult to build，most creative，most beautiful as well as other categories．But winning contests isn't the main reason why making these houses is so popular．The wonderful smell as the gingerbread bakes and the joy of eating it are the real reasons！

20．In most situations，light helps us see．But when it comes to looking at the night sky，light is actually a kind of pollution．It prevents our view of some of life's most striking sights：stars，planets，and even galaxies（銀河系）．
"When I was a little boy，I loved the night sky．I remember looking up and the sky was filled with stars．I became an astronomer because I was amazed by their beauty，"says Robert Gent，"Now in most big cities kids can't see the stars like I did．"
      Normally，about 2，500 individual （單個的） stars are visible to the human eyes without using any special equipment．But because of light pollution，you actually see just 200 to 300 and fewer than a dozen from some cities．Only one in three Americans can see our own galaxy with the naked eyes．Those people live far away from the lights of big cities，office buildings，and shopping malls．
      Fortunately，there's an inexpensive and useful way．If we shine lights down at the ground instead of up into the sky，and use lower brightness levels，we can save big amounts of energy and keep the beauty of the night sky．Many cities and towns have passed laws limiting lights at night，making sure enough shine for safety without creating much light pollution．
      Light pollution affects more than our view of the heavens and can harm wildlife．Migrating birds（候鳥） sometimes fly over cities and become confused by the brightness，flying in circles until they drop from exhaustion．  Sea turtles need dark beaches for nesting and won't approach bright lights．Too much light at night may even affect human health．For all these reasons，researchers are working on ways to use lights only when and where they are truly needed．Everyone deserves to look up at the sky．
 
71．According to the text，using our naked eyes，A．
A．people in remote areas can see more stars than those in big cities
B．over one third Americans can see our own galaxy 
C．a(chǎn)bout one in three Americans in big cities can see our own galaxy  
D．Americans can only see 200 to 300 stars
72．Many cities and towns have passed laws limiting lights at night mainly toD．
A．save the electricity                        
B．make sure of migrating birds'safety    
C．let you count the number of stars             
D．a(chǎn)void much light pollution
73．What does the fourth paragraph mainly talk about？B
A．The cause of light pollution
B．The way to reduce light pollution
C．The effect of light pollution．
D．People's attitude towards light pollution
74．The underlined word"exhaustion"in the last paragraph meansB．
A．a(chǎn)ir pollution        B．tiredness          C．breath      D．brightness
75．Which would be the best title for the text？A
A．Light Pollution   B．Seeking the Sky   C．Stars in the Sky      D．City Pollution．

7．Children's lives have changed greatly over the last 50 years．But do they have a happier childhood than you or I did？
It's difficult to look back on one's own childhood without some element of nostalgia（懷舊的）．I have four brothers and sisters，and my memories are all about being with them．Playing board games on the living room floor，or spending days in the street with the other neighborhood children，racing up and down on our bikes，or exploring the nearby woods．My parents hardly appear in these memories，except as providers either of meals or of severe blame after some particularly risky adventure．
These days，in the UK at least，the nature of childhood has changed greatly．Firstly，families are smaller，and there are far more only children．It is common for both parents to work outside the home and there is the feeling that there just isn't time to bring up a large family，or that no one could possibly afford to have more than one child．As a result，today's boys and girls spend much of their time alone．Another major change is that youngsters today tend to spend a huge amount of their free time at home，inside．More than anything this is due to the fact that parents worry far more than they used to about real or imagined dangers，so they wouldn't dream of letting their children play outside by themselves．
Finally，the kind of toys children have and the way they play is totally different．Computer and video games have replaced the board games and more interesting activities of my childhood．The iron（令人啼笑皆非的事情） is that so many ways of playing games are called"interactive"．The fact that you can play electronic games on your own further increases the sense of loneliness felt by many young people today．
Do these changes mean that children today have a less relaxing childhood than I had？I personally believe that they do，but perhaps every generation feels exactly the same．
60．What is the purpose of the direct question given in the first paragraph？A
A．To get people's attention and lead in the topic．
B．To gather people's opinions on childhood．
C．To show who the passage is written for．
D．To compare the childhood lives of two generations．
61．Which is a reason for the changes？B
A．Families are bigger today
B．It's too dangerous to play outside．
C．Children play more interactive games
D．Parents worried too much about their children．
62．What does the writer focus on in the fourth paragraph？B
A．Young people today shouldn't play electronic games．
B．Some games that young people play today aren't really good．
C．Computer and video games have replaced the board games．
D．Board games are much more interesting than computer games．
63．The writer's attitude towards the childhood changing isB．
A．a(chǎn)pproving        B．objective         C．unconcerned    D．optimistic．

4．Winter weather has returned to northern areas of the world．In much of the United States，winter means the return of snow．
Snow is a form of frozen water．It contains many groups of very small ice particles （顆粒）called snow crystals（晶體）．These crystals grow from water particles in cold clouds．They usually grow around a piece of dust．All snow crystals have six sides，but they grow in different shapes．The shape depends mainly on the temperature and water levels in the air．The shape of a snow crystal may change from one form to another as the crystal passes through levels of air with different temperatures．Snow contains much less water than rain．About 75 cm of snow has as much water as 2.5cm of rain．
Generally，the color of snow and ice appears white．This is because the light we see from the sun is white．Most natural materials take in some sunlight．However，when light travels from air to snow，some light is sent back，or reflected（反射）．Snow crystals have many surfaces to reflect sunlight．It is this light that gives snow its white color．
Much of the water we use comes from snow．Melting（融化） snow gives water to rivers and crops．Snowfall helps to protect plants and some wild animals from the cold．Fresh snow is made largely of air which is kept among the snow crystals．Because the air has trouble moving，the movement of heat is greatly reduced．However，snow is responsible for the deaths of hundreds of people in the United States every year．Many people die in traffic accidents on roads that are covered with snow or ice．
71．In the center of a snow crystal there isC
A．a(chǎn)ir       B．water      C．dust     D．sunlight
72．If fifteen centimeters of snow completely melts，the height of water will beA
A.0.5 centimeter   B.1centimeter   C.1.5 centimeters   D.15 centimeters
73．According to the text，snow looks white becauseC．
A．snow is actually white                
B．the ice particles are white
C．the reflection of light makes it look white 
D．there is a lot of air in the snow
74．How can snow protect plants from the cold？D
A．Snow gives them much heat．
B．Snow turns into water and waters them．
C．Snow makes them keep moving．
D．Snow contains air which has trouble moving．
75．What is the last paragraph of the text mainly about？C
A．Snow can give water to rivers and crops．
B．Snow can help crops keep warm in winter．
C．Snow has both advantages and disadvantages．
D．Snow is the cause of the deaths of many people．

1．Nobody knows who first invented it，but the umbrella was used in very ancient times．Probably the first to use it were the Chinese，back in the eleventh century B．C．To use it seems so natural to put up an umbrella to keep the water off when it rains．But actually the umbrella was not invented as protection against rain．It was first used as a shade against the sun．
We know it was used in ancient Egypt and Babylon as a sunshade．And there was a strange thing connected with its use； it became a symbol of honor and authority．In the Far East in ancient times，the umbrella was allowed to be used only by royal people or by those in high office．
In Europe，the Greeks were the first to use the umbrella as a sunshade．And the umbrella was in common use in ancient Greece．But it is believed that the first persons in Europe to use the umbrellas as protection against the rain were the ancient Romans．
During the Middle Ages，the use of the umbrella practically disappeared．Then it appeared again in Italy in the late 16th century．And again it became a symbol of power and  authority．By 1680，the umbrella appeared in France，and later on in England．
By the eighteenth century，the umbrella was used against rain throughout most of Europe．Umbrellas have not changed much in style during all this time，though they have become much lighter in weight．It wasn't until the twentieth century that women's umbrellas began to be made in a variety of colors．

67．Which of the following statements is not true about the umbrella？C
A．No one exactly knows who was the inventor of the umbrella．
B．The umbrella was first invented to be used as protection against the sun．
C．The umbrella changed much in style in the eighteenth century．
D．In Europe，the Greeks were the first to use the umbrella．
68．The underlined word"authority"meansC．
A．being popular     B．being useful
C．being powerful    D．being enjoyable
69．In Europe，the umbrella was first used against the rainB．
A．in Rome         B．by the eighteen century
C．in Greece       D．during the Middle Ages

A．when and how the umbrella was invented

2．How can you find out what is going on inside a person's body without opening the patient's body up？Regular X rays can show a lot．CAT scans can show even more．They can give a complete view of body organs．
What is a CAT scan？CAT stands for a kind of machine．It is a special X-ray machine that gets a 360-degree picture of a small area of a patient's body．
Doctors use X rays to study and determine diseases and injuries within the body，X rays can find a foreign object inside the body or take pictures of some inside organs to be X-rayed．
A CAT scanner，however，uses a group of X rays to give a cross-sectional（橫截面）view of a specific part of the body．A fine group of X rays is scanned across the body and around the patient from many different directions．A computer studies the information from each direction and produces a clear cross-sectional picture on a screen．This picture is then photographed for later use．Several cross sections，taken one after another，can give clear"photos"of the entire body or of any body organs．The latest CAT scanners can even give clear pictures of active，moving organs，just as a fast-action camera can"stop the action"，giving clear pictures of what appears unclear to the eye．And because of the 360-degree pictures，CAT scans show clear and complete views of organs in a manner that was once only shown during operation or examination of a dead patient．
Frequent appearance before X rays can cause skin burns，cancer or other damage to the body．Yet CAT scans actually don't cause the patient to more radiation than regular X rays do．CAT scans can also be done without getting something harmful into the patient，so they are less risky than regular X rays．
CAT scans provide exact，detailed information．They can quickly find such a thing as bleeding inside the brain．They are helping to save lives．
46．What is NOT true of a CAT scan？C
A．It is safer than regular X rays．
B．It makes use of computer techniques．
C．It can stop the action of an organ for a short time．
D．It gives clear pictures of active，moving body parts．
47．The underlined words"a foreign object"（Para 3）most probably refer to．D
A．a(chǎn) badly injured part inside the body
B．a(chǎn) new thing that is unknown to the doctor
C．a(chǎn) strange organ that has grown in the body
D．a(chǎn)n object that gets inside the body by chance
48．What is the special use of the latest CAT scanners？A
A．It provides clear photos of moving organs．
B．It can take 3-dimension（三維）pictures of inside organs．
C．It won't cause serious skin burns，cancer or other damage to the body．
D．It helps to find out what is going on inside a person's body without opening it up．
49．We can infer from this passage that．A
A．patients in front of CAT may suffer from a bit of radiation
B．doctors need no opening-up of the body with CAT scanners
C．CAT scanners are more expensive than regular X-ray machines
D．CAT scanners can take photos of either the whole body or a part of it
50．The best title of this passage might be．B
A．the Newest Medical Invention
B．New X-ray Machine to Save Lives
C．How to Avoid the Damage of X Rays
D．Advantages and Disadvantages of CAT Scanners．
