20.Women are friendly.But men are more competitive.Why?Researchers have found it's all down to the hormone oxytocin (荷爾蒙催生素).Although known as the love hormone,it affects the sexes differently.
"Women tend to be social in their behavior.They often share with others.But men lend to be competitive.Tey are trying to improve their social status,"said Professor Ryan.
Generally,people believe that the hormone oxytocin is let out in our body in various social situations ad
our body creates a large amount of it during positive social interactions (互動) such as falling in love or giving birth.
But in a previous experiment Professor Ryan found that the hormone is also let out in our body during negative social interactions such as envy.
Further researches showed that in men the hormone oxytocin improves the ability to recognize competitive relationships,but in women it raises the ability to recognize friendship.
Professor Ryan's recent experiment used 62men and women aged 20to 37.Half of the participants(參與者)received oxytocin.The other half received placebo (安慰劑).
After a week,the two groups switched with participants.They went through the same procedure with the other material.
Following each treatment,they were shown some video pictures with different social interactions.Then they were asked to analyze the relationships by answering some questions.The questions were about telling friendship from competition.And their answers should be based on gestures,body language and facial expressions.
The results indicated that,after treatment with oxytocin,men's ability to correctly recognize competitive relationships improved,but in women it was the ability to correctly recognize friendship that got better.
Professor Ryan thus concluded:"Our experiment proves that the hormone oxytocin can raise people's abilities to better distinguish different social interactions.And the behavior differences between men and women are caused by biological factors (因素) that are mainly hormonal."

25.What causes men and women to behave differently according to the text?B
A.Placebo.  B.Oxytocin.  C.The gesture.  D.The social status.
26.What can we learn from Professor Ryan's previous experiment?C
A.Oxytocin affects our behavior in a different way.
B.Our body lets out oxytocin when we are deep in love.
C.Our body produces oxytocin when we feel unhappy about others'success.
D.Oxytocin improves our abilities to understand people's behavior differences.
27.Why did Professor Ryan conduct the recent experiment?A
A.To test the effect of oxytocin on the ability to recognize social interactions.
B.To know the differences between friendship and competition.
C.To know people's different abilities to answer questions.

分析 本文屬于議論文文體.作者在文中提出荷爾蒙催生素對男女行為的不同影響:女性非常友善,善于交際,而男性更具有競爭意識,努力去提高自己的社會地位.但是實驗也表明當人內(nèi)心產(chǎn)生比如嫉妒這樣的情緒情感時人體也會釋放這種荷爾蒙催生素.此外,作者還對一項實驗進行了詳細的介紹,以此來進一步證實這一觀點.

解答 25.B.細節(jié)理解題.通過文章首段Women are friendly.But men are more competitive.Why?Researchers have found it's all down to the hormone oxytocin 可知對于男女的不同表現(xiàn),oxytocin是造成這種差異的原因,故選B.
26.C.細節(jié)理解題.根據(jù)第四段內(nèi)容…found that the hormone is also let out in our body during negative social interactions such as envy 可知當人們產(chǎn)生嫉妒這樣的情緒情感時人體也會釋放這種荷爾蒙催生素,故選C.
27.A.細節(jié)理解題.從文章末段的結(jié)論"Our experiment proves that the hormone oxytocin can raise people's abilities to better distinguish different social interaction可知教授實驗的目的就是去測試荷爾蒙催生素對社會交際能力的作用,故選A.
28.D.推理判斷題.在文章開頭作者提出荷爾蒙催生素在男女的不同表現(xiàn)中所起到的作用,也就是文章的中心話題,然后在下文中通過介紹幾個實驗及其結(jié)果來進一步對此看法進行證明,故選D.

8.When we're talking to someone,writing to our parents,or making a phone call to our friends,our words carry the message.So people communicate with words.
Can we communicate without words?The answer is"Yes".A smile on your face shows you're happy and friendly.Tears in your eyes tell others that you're sad.When you put up your hand in class,your teacher knows you want to say something or ask questions.You move your head up and down,and people know you're saying"Yes".If you move your head from side to side,you mean"No".
Other things can also carry messages.For example,a sign at the bus stop helps us to know which bus to take.A sign on the door tells us where to go in or out.There are a lot of signs around us and we receive messages all the time.
People can communicate in many other ways.An artist can use his drawings to tell about the blue sky,the green grass and many other things.Books are written to tell about all the wonderful things in the world,and also about people and their ideas.
Books,TV,radio and films all help us communicate with others.They all help us to know what is going on in the world and what other people are thinking about.
With the development of high tech,perhaps our communication ways will change a lot.

15.A rumor(傳言) of treasures has some villagers dreaming of wealth,while others see it as a cheat.It's said that in the 1800s a white man left treasures inside the caves.
This system of caves has become the center of excitement in the village of Maraigushu,near Naivasha,Kenya.It is not clear where the rumor came from,but some locals here believe white settlers hid gold and other precious metals in the cave many years ago.
Local villager Edward Maina says the rumors have brought a lot of treasure hunters flooding into town to dig in the caves.Villagers say the original treasure seekers entered the cave nearly two months ago before being arrested by police.Local governments closed up the entrance,but they broke back in.
While neither gold nor silver have been found yet,but another important resource was found:water.Many rely on a natural spring coming from the cave and local officials,among them Ward Councilor Gaka Mwaniki,worry the digging could cut off or pollute the supply."We've seen ourselves there's nothing in those caves.The cave is natural.It's the water table that they're interfering with,"says Mwaniki.
Local resident James Mbugua Njenga wants the situation brought under control.
"If at all there's treasure inside there,let the government come and dig and protect the water table,"says Njenga.
It might be true,it might be a cheat.Whatever the case,treasure hunters continue to be drawn to the mystery of the caves.

32.What did the treasure hunters do after the entrance was closed up?C
A.They looked for another cave.
B.They gave up and went home.
C.They entered the cave again.
D.They fought against the police.
33.When did the treasure hunters begin to break into the cave?D
A.In the 1800s.
B.Many years ago.
C.In spring.
D.Nearly 2months ago.
34.Mwaniki are worried that the digging may causeA.
A.the pollution to the water 
B.the loss of the treasure
C.the flood in the village
D.the terrible weather
35.The underlined phrase"interfering with"in Paragraph 4probably meansD.
A.taking pride in 
B.taking care of
C.make searching for
D.causing harm to.

5.A good deal of fascinating research has been done about the reading patterns of young people,and it is surprising to discover at what an early age children start expressing preferences for particular kind of books.A recent report,which examined in detail the reading habits of primary-school children.showed that even seven-year-old boys and girls have clear views about what they want to read.Girls,in general,read more,and far more girls than boys preferred reading stories.Boys were showing a taste for the more instant appeal of picture stories,or else books about their hobbies.
These tastes continue unchanged until the children are teenagers.Apparently girls read more in general,but more fiction in particular.You could say that there are more opportunities for girls to read fiction:magazines encourage the fiction habit in girls in their early teens,and by their late teens they have probably moved on to the adult women's magazines.Teenage boys tend to buy magazines about their hobbies:motorcycles,heavy transport and to on.
Adult reading tastes are also the subject of research.Again the number of women who read for pleasure is considerably higher than the number of men.It seems that the majority of women still want love stories.There has also been some analysis of what men actually read Apparently only 38percent of men read anything,but 50percent of what they read is fiction in the form of action-packed(內(nèi)容豐富有趣的)stories of space or gunmen
33.What has the recent research into children's reading show?D
A.Children begin to read very fast at an early age
B.Children examine in detail what they read at school
C.Children can read clearly in primary schoo1.
D.Children form their reading tastes by the time they are seven
34.If we have a close look at the reading habits of boys and girls we'll find thatA
A.girls are more interested in fiction than boys
B.girls are more interested in action-packed stories than boys
C.boys read much more than girls
D.boys have no interest in fiction
35.It can be inferred from the passage thatB.
A.boys change their reading tastes more often than girls
B.people usually do not change their reading tastes when they grow up
C.boys and girls form their reading habits by reading magazines
D.people have no definite(確切的)reading tastes.

9.Ask someone what they have done to help the environment recently and they will almost certainly mention recycling.Recycling in the home is very important,of course.However,being forced to recycle often means we already have more material than we need.We are dealing with the results of that over-consumption in the greenest way possible,but it would be far better if we did not need to bring so much material home in the first place.
    The total amount of packaging has increased by 12% between 1999 and 2005.It now makes up a third of a typical household's waste in the UK.In many supermarkets nowadays food items are packaged twice with plastic and cardboard.
Too much packaging is doing serious damage to the environment.The UK,for example,is running out of it for burying this unnecessary waste.If such packaging is burnt,it gives off greenhouse gases which go on to cause the greenhouse effect.Recycling helps,but the process itself uses energy.The solution is not to produce such items in the first place.Food waste is a serious problem,too.Too many supermarkets encourage customers to buy more than they need.However,few of them are coming round to the idea that this cannot continue,encouraging customers to reuse their plastic bags,for example.
But this is not just about supermarkets.It is about all of us.We have learned to associate packaging with quality.We have learned to think that something unpackaged is of poor quality.This is especially true of food.But it is also applied to a wide range of consumer products,which often have far more packaging than necessary.
There are signs of hope.As more of us recycle,we are beginning to realize just how much unnecessary materials are collected.We need to face the wastefulness of our consumer culture,but we have a mountain to climb.
31.What does the underlined phrase"over-consumption"refer to?C
A.Using too much packaging
B.Recycling too many wastes.
C.Having more material than is needed
D.Making more products than necessary.
32.The author uses figures in Paragraph 2 to showC.
A.the tendency of cutting household waste   
B.the increase of packaging recycling
C.the fact of packaging overuse            
D.the rapid growth of supermarkets   
33.According to the text,recyclingB.
A.means burning packaging for energy      
B.helps control the greenhouse effect   
C.is the solution to gas shortage             
D.leads to a waste of land
34.What can be inferred from Paragraph 4?D
A.Unpackaged products are of bad quality.
B.Supermarkets care more about packaging.
C.Other products are better packaged than food.
D.It is improper to judge quality by packaging.
35.What can we learn from the last paragraph?B
A.Needless material is mostly recycled.
B.Fighting wastefulness is difficult.
C.People like collecting recyclable wastes.
D.The author is proud of their consumer culture.

10.In 2009,a French company auctioned(拍賣)two treasures-a rat's head and a rabbit's head robbed from China,(61)which has caused great public concern in China.
(62)It is known to all that the two bronze animal heads were made during the Qing Dynasty(63)to decorate(decorate)Yuanmingyuan Imperial Garden.In 1860,it was the British and French troops (64)that broke into Beijing,burning down the royal garden.Millions of Chinese art works were taken away,(65)including (include)the rat's head and the rabbit's head.
The Chinese government was strongly against the auction and had repeatedly asked for the free return of the two (66)valuable (value)relics according to the international laws.Some Chinese people even (67)flew (fly)to France,trying to stop the selling.(68)However,the French company just wouldn't listen.
As far as I am concerned,the auction should be strongly condemned(譴責).Not only has it hurt the feelings of the Chinese people but also it has done harm to the relationship between France and China.As middle school students,we must study (69)harder (hard) so that we can make our country more powerful in the future and stop any such thing (70)from happening again.
