11.About ten men in every hundred suffer from color blindness in some way.Women are luckier,only about one in two hundred is affected in this matter.Perhaps,after all,it is safer to be driven by a woman!
There are different forms of color blindness.In some cases a man may not be able to see deep red.He may think that red,orange and yellow are all shadows of green.Sometimes a person cannot tell the difference between blue and green.In rare cases an unlucky man may see everything in shades of green-a strange world indeed.
Color blindness in human beings is a strange thing to explain.In a single eve there are millions of very small things called"cones".These help us to see in a bright light and to tell the difference between colors.
There are also millions of"rods",but these are used for seeing when it is near dark.They show us shape but no color.
Some insects have favorite colors.Mosquitoes(蚊子)prefer blue to yellow.A red light will not attract insects,but a blue lamp will.In a similar way human beings also have favorite colors.Yet we are lucky.With the aid of the comes in our eyes we can see many beautiful colors by day,and with the aid of the rods we can see shapes at night.One day we may even learn more about the invisible(看不見(jiàn)的)colors around us.

61.the passage is mainly aboutD.
A.color and its surprising effects
B.women being luckier than men
C.danger caused by color blindness
D.color blindness
62.According to the passage,with the help of the"cones",we canD.
A.tell different shapes
B.see in a weak light
C.kill mosquitoes
D.tell orange from yellow
63.Why do some people say it is safer to be driven by women?B
A.Women are more careful.
B.There are fewer color-blind women.
C.Women are fonder of driving than men.
D.Women are weaker but quicker in thinking.
64.Which of the statements about the color-blind is true?A
A.Not all of them have the same problem in recognizing color.
B.None of them can see deep red.
C.None of them can tell the difference between blue and green.
D.All of them see everything in shades of green.
65.We can attract and kill mosquitoes by using aC.
A.red light  B.yellow light  C.blue light  D.green light.

分析 色盲是什么原因引起的?色盲患者無(wú)法正確分辨顏色;而我們能分辨顏色和形狀則是靠了眼睛里的兩種細(xì)胞:視桿細(xì)胞和視錐細(xì)胞.

解答 61.D主旨大意題.本文主要講了色盲的表現(xiàn)和人的眼睛看見(jiàn)形狀和顏色的原因.DB細(xì)節(jié)理解題.由"These help us see in a bright day and tell the differences between colors."可知視錐細(xì)胞可以讓我們分辨不同的顏色.故選D.
62.D 推理判斷題.根據(jù)句子These help us to see in a bright light and to tell the difference between colors.這些有助于我們?cè)诿髁恋墓饩下看到,并辨別顏色之間的區(qū)別.可以推斷出能幫助辨別黃色和橘色的,這就是"cones"的幫助作用,所以答案選D.
63.B 細(xì)節(jié)理解題.由"Women are luckier,only about one in two hundred if affected in this matter.Perhaps,after all,it is safer to be driven by a woman."可知女性色盲的比例要少于男性,因此開(kāi)車(chē)或許更安全.所以答案選B.
64.A 細(xì)節(jié)理解題.由"There are different forms of color blindness."可知色盲患者的類型并不相同. 故選A.
65.C 推理判斷題.根據(jù)句子Some insects have favorite colors.Mosquitoes(蚊子)prefer blue to yellow有些昆蟲(chóng)有最喜歡的顏色.蚊子(蚊子)喜歡藍(lán)色黃色.A red light will not attract insects,but a blue lamp will.紅燈不會(huì)招引昆蟲(chóng),但藍(lán)色的燈會(huì).可以推斷出藍(lán)色可以吸引和捕殺蚊子,所以答案選C.

點(diǎn)評(píng) 閱讀理解題測(cè)試考生在閱讀基礎(chǔ)上的邏輯推理能力,要求考生根據(jù)文章所述事件的邏輯關(guān)系,對(duì)未說(shuō)明的趨勢(shì)或結(jié)局作出合理的推斷;或根據(jù)作者所闡述的觀點(diǎn)理論,對(duì)文章未涉及的現(xiàn)象、事例給以解釋.考生首先要仔細(xì)閱讀短文,完整了解信息,準(zhǔn)確把握作者觀點(diǎn).

19.For some kids,old photos and baby pictures are embarrassing.For others,they are cherished keepsakes(紀(jì)念品).But for thousands of children living in orphanages(孤兒院)worldwide,these records of the past simply don't exist.Either the kids'parents weren't around to snap photos,or the pictures have been lost.Whatever the reason is,the Memory Project is giving orphans a lasting document of their youth.
Over the last two years,the Memory Project has provided hand-painted portraits (肖像)for more than 4,000 children living in orphanages in poor countries.Ben Schumaker,24,got the idea when he was visiting an orphanage in Guatemala in Central America.But he's not creating the portraits alone.Students in hundreds of high school art classes across the U.S.paint them using photos sent from the orphanages.
Schumaker believes that the artists benefit from the project as much as the orphans do."There are two purposes of the Memory Project,"he said."One is to offer a special gift to the child abroad.The other is to help open the eyes of the student who is painting."Staring into the eyes of another person,Schumaker believes,creates a real connection.This connection raises awareness in U.S.schools about the needs of the world's poor children."It's about planting a seed,"he said.
Schumaker is also working on Books of Hope,a project in which students of all ages put together homemade books for children in Uganda and India.He hopes that one day children in Uganda and India will send books to the U.S."It's important for me to have it be a two-way exchange,"Schmnaker says.

25.Old photos and baby pictures are clearly unavailable toC.
A.the kids in rich families
B.the kids in common families
C.the kids without parents
D.the kids in expanded families
26.What does the underlined word"document"in the first paragraph most probably mean?B
A.money
B.record
C.a(chǎn)ppeal
D.doubt
27.How can the orphans in Guatemala get a continuing record of their youth?B.
A.By hand-painted portraits that Ben Schumaker painted.
B.By the Memory Project started by Ben Schumaker.
C.By the photos taken by the U.S.students in high schools.
D.By the photos the orphanage takes for them.
28.What does the third paragraph mainly tell us?C
A.The special gifts that the world's poor children received.
B.The need of the US schools.
C.The advantages that the Memory Project brings.
D.How to help the orphans.

3.Can you imagine that several hundred years ago,tomatoes were seen as toxic food in Europe?
What made Europeans believe this was John Gerard's publication of Herbal in 1597.Gerard wrote:"The leaves and stalks of the tomato plant are toxic."Undoubtedly,Gerard's opinion was based on a misunderstanding of tomatoes.But his opinion was widely spread in Britain and North America for over two hundred years.
In the late 1700s,a lot of Europeans held more fears for tomatoes.A nick name for the fruit was"poison apple"because it was believed that aristocrats(貴族) got sick and died after eating them.But the actual reason was the pewter plates they used.Since tomatoes are high in acidity,when placed on the plates,the lead(鉛) in the plates would dissolve.This caused many deaths.Unluckily,no one knew this at that time.So the innocent tomatoes were picked as the killer.
Today,more than one and a half billion tons of tomatoes are produced every year around the world.Tomatoes are cooked in various ways.This healthy and tasty food finally wins its innocence(清白) back.

51.Which of the following can be the best title for this passage?A
A.Europeans'fears for tomatoes
B.History of tomato planting
C.Why do people eat so many tomatoes
D.How did the tomato prove its value
52.What does the underlined word"toxic"in paragraph 1mean?C
A.delicious        
B.nutritious(營(yíng)養(yǎng))       
C.poisonous      
D.safe
53.What do we know about the book Herbal?B
A.It was written by an American writer.
B.It was published about 400years ago.
C.Tomatoes were described as good food.
D.Chinese herbal medicine was included.
54.When did people begin to eat tomatoes according to the text?B
A.About 100years ago.
B.About 200years ago.
C.About 300years ago.
D.About 400years ago.
55.What's the key point for the death of the aristocrats mentioned in the passage?D
A.Tomatoes.
B.The pewter plate.
C.Serious illness.
D.Chemical reaction.
