19.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 tend to be competitive.They 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 and our body creates a large amount of it during positive social interactions (互動(dòng)) 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 62 men and women aged 20 to 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.
D.To test people's understanding of body language.
28.The author develops the text byD.
A.explaining people's behaviors

解答 BCAD
25 B   細(xì)節(jié)理解題   根據(jù)第一段"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)"可知,研究人員發(fā)現(xiàn)女人友好,男人更具競(jìng)爭(zhēng)力,這一切都取決于荷爾蒙催生素;故選B
26C   細(xì)節(jié)理解題    根據(jù)第三段"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"可知,在 Ryan 教授以前的一次試驗(yàn)中發(fā)現(xiàn),在消極的社會(huì)交往中,例如嫉妒時(shí),荷爾蒙也會(huì)從我們體內(nèi)釋放出來;故選C
27 A   細(xì)節(jié)推理題   根據(jù)最后一段Ryan教授得出的結(jié)論"Our experiment proves that the hormone oxytocin can raise people's abilities to better distinguish different social interactions."可知,他實(shí)驗(yàn)的目的在于證實(shí)了荷爾蒙催生素能提升人們更好地區(qū)分不同社交互動(dòng)的能力;故選A
28 D    內(nèi)容歸納題     通讀全文可知,本文主要介紹了一些有關(guān)荷爾蒙催生素的研究發(fā)現(xiàn),以及Ryan教授與之相關(guān)的以前的與更進(jìn)一步的實(shí)驗(yàn)結(jié)果;故選D

點(diǎn)評(píng) 一、速讀全文,了解大意知主題.
  閱讀能力一般指閱讀速度和理解能力兩個(gè)方面.閱讀速度是閱讀最基本的能力.考生必須在十分有限的時(shí)間內(nèi)運(yùn)用略讀、掃讀、跳讀等技巧快速閱讀,搜尋關(guān)鍵詞、主題句,捕捉時(shí)空、順序、情節(jié)、人物、觀點(diǎn),并且理清文章脈絡(luò),把握語(yǔ)篇實(shí)質(zhì).
二、看題干,帶著問題讀文章.
  首先要掌握問題的類型,客觀信息題可以從文章中直接找到答案;而主觀判斷題考查的是對(duì)文章的感情基調(diào)等,這類題必須經(jīng)過對(duì)作者的態(tài)度、意圖以及對(duì)整篇文章進(jìn)行深一層的推理等.其次,了解試題題干以及各個(gè)選項(xiàng)所包含的信息,然后有針對(duì)性地對(duì)文章進(jìn)行掃讀,對(duì)有關(guān)信息進(jìn)行快速定位.此法加強(qiáng)了閱讀的針對(duì)性,提高了做題的準(zhǔn)確率.
  三、邏輯推理,做好深層理解題.
  在實(shí)際閱讀中,有時(shí)作者并未把意圖說出來,閱讀者要根據(jù)字面意思,通過語(yǔ)篇邏輯關(guān)系,研究細(xì)節(jié)的暗示,推敲作者的態(tài)度,理解文章的寓義.要求讀者對(duì)文字的表面信息進(jìn)行分析、挖掘和邏輯推理,不能就事論事,以偏概全.推理題在提問中常用的詞有:infer,imply,suggest,indicate等.
  四、猜詞悟義,掃除閱讀攔路虎.
  猜詞是應(yīng)用英語(yǔ)的重要能力.它不但需要準(zhǔn)確無誤地理解上下文,而且要有較大的泛讀量,掌握或認(rèn)識(shí)較多的課外詞匯.我們要學(xué)會(huì)"順藤摸瓜",通過構(gòu)詞,語(yǔ)法,定義,同位,對(duì)比,因果,常識(shí),上下文等線索確定詞義.

14.One August afternoon,Richard Allen dropped off his last passenger,Mrs.Carey.Lifting two grocery bags,he followed her across the yard and stood on the step of her house.Glancing up,he saw a large wasp (黃蜂) nest under the roof.Allen had heardthat wasps can become more likely to sting in summer.He mentioned this to Mrs.Carey,who had opened the oor.
"Oh,hey don't bother me,"she said lightly."I go in and out all the time."
Anxiously,Allen looked at the nest again-to see the wasps flying straight at him."Hurry!"he shouted to Mrs.Carey."Get in!"
She stepped quickly inside.Allen ran for his mini-bus.Too late; they were upon him.Just as he jumped aboard,half a dozen red spots showed on his arm,and he felt more on his back and shoulders.
As he was driving down the road,Allen felt as if somethng was burning at the back of his neck,and the"fire"was spreading forward toward his face.An immediate anxiety took hold of him.Allen knew that stings could cause some persons to die.But he had been stung the previous summer and the after-effects soon passed.However,what he didn't know was that the first sting had turned his body into a time bomb waiting for the next to set off an explosion.
Miles from the nearest medical assistance,Allen began to feel his tongue thick and heavy and his heartbeat louder.Most frightening,he felt his breathing more and more difficult.He reached for the radio mike (話筒),trying to call the mini-bus center,but his words were hardly understandable.Signals were also poor that far out.He knew a rescue team was on 24-hour duty at the Amherst Fire Department's north station.So his best chance was to make a run for it.
Rushing down the mountain,Allen tried not to panic,focusing his ind on each sharp turn.He was almost through the last of them when he felt sure he was going into shock (休克).Just then he reached for the radio mike again.
"Call fire station,"he shouted,concentrating to form the words."Emergency.Bee sting.Emergency.There in ten minutes."
"Five-ten."the center replied.
Hold on,Allen thought.Keep your eyes open.Breathe.Keep awake.
At last he reached the station.Two firemen ran out.Allen felt their hands grasp him before he hit the ground.You made it,he thought.

56.It is mentioned in the passage that wasps are more likely to attack whenD.
A.there are huge noises
B.strangers are approaching
C.the air is filled with food smell
D.the hottest season comes around

A.have no after-effects
B.suffer from sharper pain
C.surely lose his life
D.become more sensitive
58.Allen failed at his first attempt to send his message to the mini-bus center becauseA.
A.he was unable to speak clearly
B.his radio equipment was poor
C.he was in a state of shock
D.no one was on duty
