7.While learning the science lessons,I used to get a doubt--why ear,nose,tongue and eyes should be called as special senses?The basic reason is that these are the channels through which we maintain contact with the surroundings.Though apparently it may feel like these are individual sensory organs,they do show some connectivity.Interestingly,our hearing is less sharp after we eat a heavy food.Isn't it good for a sound nap after a stomach-full meal?That does not mean we go deaf after a meal,but the hearing pitch(強(qiáng)度)does change after a heavy meal.
We usually give credit of the taste to our tongue,but do you know that unless saliva(唾液)dissolves something,our tongue cannot recognize the taste of the food eaten.Taste is nothing but the food chemicals dissolved in the saliva being sensed by the taste buds(味蕾)present on the tongue. Try to dry off your tongue and mouth with a tissue paper and then taste something.
Women are much better smellers than men.They are born with this characteristic ability and can correctly recognize the exact fragrance of the sample.We all can store almost 50,000different smells,which are strongly tied to the memories.
Pupils(瞳孔)do not respond to light alone,but to the slightest bit of noise around too.Thus surgeons,watchmakers and those professionals who have to perform a much delicate job do prefer to have a sound-free environment.Even a small noise can enlarge their pupils,change the focus and make their vision less clear.
Each and every one of us has a particular or individualistic or characteristic smell,which is unique to us,except the twins.This smell is very subtle yet can be sensed even by a newborn.It may be due to this smell that the newborn recognizes the presence of his parents around.

72.What may happen after you have had a rich lunch?C
A.Your eyes become weak and can not see well.
B.You may feel energetic and fresh.
C.Your hearing pitch may be decreased.
D.Your tongue may lose the function of taste.
73.What does the author mean by the underlined sentence in paragraph 2?B
A.Our tongues can't be dried while eating something.
B.If your tongue is dried without any saliva on it,it will not work.
C.A tissue paper is the only thing that can be used to dry our tongues.
D.If your tongue is dried with a tissue paper,it may work as well as before.
74.What makes each person different from anyone else except twins according to the passage?C
A.The number of sensory organs.B.The functions of sensory organs.
C.The particular smell of a person.D.The style of one's behavior.
75.Which of the following may be the best title of this passage?B
A.The Sensitivity of Sensory Organs
B.The Functions and Connections of Sensory Organs
C.A Newborn's Sensory Organs
D.Different Senses Between Men and Woman.

解答 72-75 CBCB
72.C 細(xì)節(jié)題.根據(jù)第一段倒數(shù)一、二句"Isn't it good for a sound nap after a stomach-full meal?That does not mean we go deaf after a meal,but the hearing pitch(強(qiáng)度) does change after a heavy meal."可知吃飽后人的聽覺會(huì)降低.故正確答案為C.
73.B 主旨題.根據(jù)第二段內(nèi)容可知,舌頭必須在唾液的配合下才能分辨味道,如果用紙把舌頭擦干,舌頭的味覺功能就會(huì)喪失.故正確答案為B.
74.C 推斷題.根據(jù)最后一段可知,作者認(rèn)為我們每個(gè)人身上都有獨(dú)特的味道,通過這個(gè)味道我們就可以辨別我們所熟悉的人.故正確答案為C.
75.B 主旨題.結(jié)合全文可知此文章是介紹感覺器官的功能和作用.故正確答案為B.

點(diǎn)評(píng) 做閱讀時(shí)經(jīng)常犯錯(cuò)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(duì)于題目的理解一定要忠實(shí)于原文,因此,每一道題都應(yīng)該與原文作全面的對(duì)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(xiàng)(2)排除與原文相關(guān)句態(tài)度相反的選項(xiàng)  (3)排除用于過于極端或負(fù)面的選項(xiàng)(4)注意結(jié)合文章主旨和主題去排除.

15.Have you ever suddenly felt that someone you knew was in trouble-and was he?Have you ever dreamed something that came true later?Maybe you have ESP(特異功能).ESP stands for Extrasensory Perception.It may be called a sixth sense.It seems to let people know about events before they happen,or events that are happening some distance away.
Here's an example.A woman was ironing clothes.Suddenly she screamed,"My father is dead!I saw him sitting in the chair!"Just then,a telegram came.The woman's father died of a heart attack.He died sitting in a chair.
There are thousands of stories like this one on record.Scientists are studying them to find out what's behind these strange mental messages.Here's another example-one of hundreds of dreams that have come true.
A man dreamed he was walking along a road when a horse and carriage came by.The driver said,"There's room for one more."The man felt the driver seemed dead,so he ran away.The next day,when the man was getting on a crowded bus,the bus driver said."There's room for one more."
Then the man saw that the driver's face was the same face he had seen in the dream.He wouldn't get on the bus.As the bus drove off,it crashed and burst into flames.Everyone was killed!
Some people say stories like these are coincidences.Others,including some scientists,say that ESP is real.From studies of ESP,we may someday learn more about the human mind.
59.According to the passage,the author believes that the sixth sense isA.
A.possible    B.imaginativeC.not real    D.impossible
60.By studying ESP,scientists may get toC.
A.learn how people tell lies     
B.know more about human dreams
C.know more about human mind     
D.learn how strange things happen
61.In the last paragraph the underlined word"coincidences"probably means"B".
A.things that may not happen     
B.things that happen by accident
C.things that must happen     
D.things that happen in a dream
62.This article is mainly aboutD.

2.Do you have any skiing equipment you no longer need?A ski school in the far north of India could put it to good use.
In March we published a photo story about the extraordinary Zsnskar region in northern India,which is cut off from the outside world for more than seven months of the year,and only accessible (可通行的)via a frozen river.We also included information about the limited use of skiing in the region and the recent creation of the Zanskar Ski School:"Despite the difficulties of travelling through the region when the snow comes,skiing hasn't traditionally been used as a means of transport by the locals,largely because trees don't grow here,so there is little in the way of raw materials from which to make skis.In 1995,a group of British scientists in the region noticed the lack of skis and one of them returned to set up the Zanskar Ski School in Padam.The school provides lessons for a small fee and rents skis to the local people.Among the benefits that the school hopes to bring are improved education-children often find it difficult to get to school through the deep snow-and the possibility of offering ski tours to tourists in the future.So far,more than 300 local people have received training,and local doctors and  policemen regularly borrow skis."
But what we weren't able to include in the article is that the ski school is always on the look out for old skiing equipment-particularly of a size suitable for children-and,I thought.Now the European ski season is drawing to a close,there might be a few of you out there who have some old equipment you'd like to see go to a good home.If that's the ease you can get in touch with the school via their website www.zanskarski school.org.

56.What's the purpose in writing the text?D
A.To raise money to develop this area
B.To attract more tourists to the area
C.To appeal to more locals to attend the school
D.To ask people to give away their skis to the school
57.Who would be the most helpful to the school now?A
A.People having old skiing equipment.     B.Students in the Zanskar Ski School.
C.Locals in Zanskar region.               D.Tavellers enjoying skiing.
58.What can be the best title for the text?B

19.What science story once told about other worlds far away is now a fact.Astronomers prove another solar (of the sun) system like ours with some planets in the constellation Andromeda (仙女座).
Geoffrey Marcy is a professor of astronomy and physics at San Francisco State University.He says,"What we have found now is indeed a fully-grown system of planets around the star Upsilon Andromeda.It appears to have three planets,one close in,one at a middle distance,and one farther out.The star is slightly larger than our sun.The planets are huge,like our Jupiter(木星)."
Marcy's partner in this research,Debra Fischer,describes the solar system,"Here are the inner planet that goes around every 46 days,the middle planet that goes around every 242 days,and then the outer planet that goes around every three and a half to four years."
The sun of that solar system,Upsilon Andromeda,is so near and bright that it can be seen by using no equipment during summer and fall.
For twelve years astronomers searched the skies in the belief that if our sun has planets around it,surely others do,too.Geoffrey Marcy says,"And then starting three and a half years ago,we began finding for the first time planets singly,one planet here around one star…"
"When I look up at the stars now at night,I can imagine easily that every one of them has planets around them,"says Debra Fischer.
It was a tremble (shaking) in the star that led Marcy to the planets."The star rocks around because of the gravity of the planet as a dog owner gets pulled around by a little dog."
Can they support life?We don't know,because present technology is not advanced enough to determine what the planets are made of.That,Marcy says,is astronomy's next challenge.
32.What's the relation between Andromeda (A),Upsilon Andromeda system (U) and the mentioned three planets (P)?D
                  
33.According to Debra Fischer,in the new solar system,B.
A.the larger a planet is,the shorter it takes to go around the star
B.the farther a planet is from the star,the longer it takes to go around the star
C.it takes all the planets around three and a half to four years to go around the star
D.the planets move around the star at the same speed
34.What led to Marcy's discovery of the planets?C
A.That any planet has gravity.
B.That a dog owner was pulled by his dog.
C.The tremble of Upsilon Andromeda.
D.That any star has its planets.
35.We can infer (推斷) that the scientists areA.
A.to find out whether the planets can support life
B.to find means to travel to the planets
C.to communicate with the living beings on the planets
D.soon to be able to answer the question.
