14.WHEN you get hungry,do you find yourself making poor decisions?Well,it turns out that this is because of a hormone called ghrelin (饑餓激素).
It is released when you are hungry and has a bad effect on impulses (沖動(dòng)) and making decisions,according to a recent study at Sahlgrenska Academy,part of the University of Gothenburg in Sweden.
"For the first time,we have been able to show that increasing ghrelin to levels that are seen when hungry causes the brain to act impulsively and also affects the ability to make rational decisions,"Karolina Skibicka,a member of the teaching staff at Sahlgrenska Academy,told the Science Daily website.
Impulsivity is complex,according to the website,but impulsive choice basically means not being able to resist the temptation  to take a reward now instead of waiting until later.
You may sometimes eat a bag of chips even though you know that you're going to have dinner soon,for example.This type of problem was seen in the rats used in the study.
The rats were trained to be rewarded with sugar when they did something like pressing a lever (杠桿)-or instead,they could be rewarded only when they stopped themselves from pressing the lever ("no-go") when the right signal,like a flash of light or a buzzing sound,was given.
When rats could not stop themselves from pressing the lever when the"no-go"signal was given,it was seen as a sign of impulsivity.Researchers found that rats given ghrelin directly into the brain were more likely to press the lever instead of waiting,even though it caused them to lose their reward.
The ability to wait for a greater reward later measures impulsive choice.For example,you can overeat fattening foods to feel happy right now or choose to eat healthier.Researchers at Sahlgrenska Academy found that higher levels of ghrelin stopped the rats from being able to wait for the greater reward.
The study also showed that increased levels of ghrelin even caused long-term genetic changes in the brain parts that are connected to impulsivity and decision making.The same type of changes can be seen in brains with attention deficit hyperactivity disorder (ADHD) (注意力缺陷多動(dòng)障礙) and other psychiatric disorders (精神疾。,reported Science Daily.
"The ghrelin receptors in the brain can be a possible target for future treatment,"said Skibicka.
32.According to the article,in the study at Sahlgrenska Academy,C.
A.the rats could only get their reward when they pressed a lever
B.when ghrelin in the rats'brains increased,they could wait for the right signal
C.when ghrelin in the rats'brains increased,they were more likely press the lever
D.when ghrelin in the rats'brains increased,they were eager to get the sugar
33.According to the article,impulsivity is measured byA.
A.the ability to focus on now rather than later 
B.the number of risks taken
C.the amount of patience for waiting     
D.the ability to wait for a good or better reward
34.Which word is closest to the meaning of the underlined word"rational"?A
A.wise      
B.quick       
C.difficult        
D.simple
35.What's the article mainly about?B
A.Impulsivity and decision-making.
B.Ghrelin and impulsivity.
C.Ghrelin's increase when people are hungry.
D.The way in which increasing ghrelin causes genetic changes.

4.For centuries,the body's blood has been linked closely with the emotions.People who show no human emotions or feelings,are said to be cold-blooded killer.For example,the police are searching for a cold-blooded killer.He seems to kill for no reason,and no emotion,as if taking someone's life as nothing.
Cold can affect other parts of the body.The expression"get cold feet"has nothing to do with cold or your feet.The expression means being afraid to do something you have decided to do.For example,you agree to be president of an organization.But then you learn that all the other officers have resigned,and all the work of the organizations will be your responsibility.You are likely to get cold feet about being president when you understand the situation.
The expression"give someone the cold shoulder"probably comes from the physical act of turning your back toward someone instead of speaking to him face to face.You may give a cold shoulder to a friend who has not kept a promise he made to you.Or,to someone who has lied about you to others.
A cold fish is not a fish.It is a person.But it is a person who is unfriendly,unemotional and shows no love or warmth.A cold fish does not offer much of himself to anyone.Someone who is a cold fish could be cold-hearted.Now a cold-hearted person is someone who has no sympathy.Several popular songs in recent years were about cold-hearted men or cold-hearted women who,without feelings,broke the hearts of their lovers.
"Out in the cold"means not getting something that everybody else got.A person might say that everybody but him got a pay raise--he was left out in the cold.And it is not a pleasant place to be.
56.There areC expressions related to cold that are mentioned in the passage.
A.3B.4C.6D.7
57.When you refuse to speak to a man and treat him in a distant way,you may express by"A".
A.I give him the cold shoulder 
B.I think he is a cold-blooded man
C.I think he is a cold fish
D.I'm likely to get cold feet
58.If Sue shows absolutely no reaction to those awful pictures of starving children in Africa,you will sayC.
A.she is a cold-blooded killer
B.she gets cold feet
C.she is a cold fish
D.she is out in the cold
59.We can use the expression"D"to describe a man who abandons or hurts his lover without mercy.
A.cold-blooded
B.cold shoulder
C.cold feet
D.cold-hearted
60.The topic of this passage is aboutC.
A.the relationship between cold and our body
B.some expressions about friendship
C.some expressions connected with cold
D.how cold weather comes into being.

5.People say teenagers are no good.They make too much noise in shopping malls; they drive recklessly up and down America's main streets; they carry chips on their shoulders as big as the Sears Tower.And at least some of the time those things are true.But we shouldn't forget that there are hard moments in the life of a teenager too.
I watched such a moment not long ago at a woman's funeral.I didn't expect the event to affect me.Through much of the ceremony,in fact,I remained unmoved.
The teenage grandson stepped forward.With his very first deep breath,every heart in that church was achingly reminded of something we had all forgotten.Softly he began:"I want to share a few values that Nana taught me.She never failed to see light in any situation.When our family dog would truly attack her,what would Nana say?'oh,what beautiful barking that dog has!'That was Nana."
"She was a strong woman who often lived in the shadow of my grandpa,who was a successful businessman in this city.But she was the one behind the scenes who provided the strength and support for my grandpa's career,"he said,with a voice now trembling,"That was Nana's way."
Through a low sob,he continued,"Whenever she did anything worth recognition,you'd have to hear about it from a different source,because she was never one to show off."
Finally,in a voice breaking free of sorrow,he looked up and said,"Nana taught me courage.She put up an incredible fight to the end,when she died peacefully,which is how she lived her life.That was Nana's way,and I hope I can carry on in the same manner."
There are no hearts as sensitive as those of teenagers,because everything is happening to them for the first time.The trouble with teenagers is that they haven't learned to be controlled.When that boy rose to speak about the woman who surely had been his truest and best friend,his honest voice dragged each of us out into the open where we could no longer hide in the calm ceremony.He exposed us to the truth about this very real woman who believed in a boy who probably tried the patience of many adults.He reminded us that his grandmother was more than another dot on the chart of life and death.
All over again we felt those powerful losses crossing our own hearts,and we knew that when you say good-bye to something happy,something young in yourself.And that something never really returns,and the pain never really goes away.
32.In the first paragraph,the writer gave some examples toD.
A.support his idea that young people are no good
B.introduce his point of view about young people
C.tell people every coin has its two sides
D.show young people often make mistakes
33.From the boy's speech,we knowA.
A.his grandmother had great influence on him
B.they had a dog which often attacked people
C.people had forgotten her until the boy appeared
D.his grandmother was so weak that she is always living in the shadow of his grandpa
34.Which of the following statements is true?D
A.The boy's speech moved no one present at the funeral except the writer
B.The boy's being good at expressing himself enabled him to draw everyone's attention
C.The boy was too grieved to accept the fact that his grandmother had passed away
D.The writer didn't expect the event would affect him
35.What words can best describe grandmother's quality?D

2.The life expectancy is the length of time that a person is normally likely to live.As it increases nowadays,the average person lives beyond the age of retirement.As a result,the elderly make up an ever-increasing percentage of society,which makes it more important to make effort to improve the lives of senior citizens.
First of all,one way would be to make sure that the elderly have enough money on which to live.Obviously,when a person stops working,they still require a source of income to cover their basic needs such as food,accommodation and heating.A clear solution to the problem is for the government to make sure that the state pension(養(yǎng)老金) is enough for these needs.
Measures should also be taken to overcome the health problems the elderly face.The government should also provide access to the best health care available,which may necessitate paying for residential homes where the elderly can have round-the-clock nursing,or,at least,providing medication free of charge to all people over a certain age.
If we try to address the problem of social isolation (社交孤立),the lives of old people could be improved.If we organize trips for the elderly to community centers,visits from social workers,their problem of loneliness can be reduced a lot which marks the lives of so many old people living alone and far from their families.
The last helpful suggestion is to change the attitude of the community towards its older members,who are all too often seen as a burden on society.We need to be taught from an early age to respect the views of old people,and appreciate their broader experience of life.This would help society as a whole,and encourage appreciation of the role that old people can still play today.
49.What does underlined word"it"in Paragraph 1refer to?C
A.time     
B.retirement     
C.life expectancy     
D.a(chǎn)ge
50.What factors affected the old people's life?C
a.the state pension
b.the basic needs
c.the attitude of the community
d.the experience of life
e.social isolation
f.medical care
A.b,c,d,e      
B.a(chǎn),b,c,d    
C.a(chǎn),c,e,f    
D.c,d,e,f
51.According to the last suggestion,the old peopleA.
A.should be respected by all of us
B.may be regarded as our heavy burden
C.must change their attitude to the community
D.have to gather more life experience.

9.Grammar is the system of a language.People sometimes describe grammar as the"rules"of a language; but in fact no language has rules.If we use the word"rules",we suggest that somebody created the rules first and then spoke the language,like a new game.But languages did not start like that.Languages started by people making sounds which evolved (逐漸發(fā)展成) into words,phrases and sentences.No commonly-spoken language is fixed.All languages change over time.What we call"grammar"is simply a reflection (反映) of a language at a particular time.
Do we need to study grammar to learn a language?The short answer is"no".Very many people in the world speak their own,native language without having studied its grammar.Children start to speak before they even know the word"grammar".But if you are serious about learning a foreign language,the long answer is"yes,grammar can help you to learn a language more quickly and more efficiently."It's important to think of grammar as something that can help you,like a friend.When you understand the grammar (or system) of a language,you can understand many things yourself,without having to ask a teacher or look in a book.
So think of grammar as something good,something positive,something that you can use to find your way---like a signpost(路標(biāo)) or a map.
Except invented languages like Esperanto(世界語).And if Esperanto were widely spoken,its rules would soon be very different.
21.Which of the following statements is NOT true?B
A.Grammar is the system of a language.
B.Someone created the grammar first and then people learn the language according to it.
C.Language's developing and forming is a long-term process (過程).
D.There is no language staying the same all the time.
22.What is the author's attitude towards grammar learning?C
A.He is against grammar learning.
B.He is in favor of grammar learning.
C.His attitude is objective(客觀的).
D.His attitude is unknown to us.
23.Which of the following is CORRECT according to the last paragraph?C
A.Esperanto is widely spoken.
B.Esperanto is different from other languages because its rules are fixed.
C.Esperanto is different from other languages because its rules came out before this language.
D.Esperanto is very easy to learn.

3.Still seeking a destination for your weekend break?There are some places which are probably a mere walk away from your college.
King's Art Centre
     A day at the Centre could mean a visit to an exhibition of the work of one of the most interesting contemporary artists on show anywhere.This weekend sees the opening of an exhibition of four local artists.
     You could attend a class teaching you how to‘learn from the masters'or get more creative with paint-free of charge.
     The Centre also runs two life drawing classes for which there is a small fee.
the Botanic Garden
     The Garden has over 8,000 plant species; it holds the research and teaching collection of living plants for Cambridge University.
     The multi-branched Torch Aloe here is impressive.The African plant produces red flowers above blue-green leaves,and is not one to miss.
     Get to the display house to see Dionaea muscipula,a plant more commonly known as the Venus Flytrap that feeds on insects and other small animals.
     The Garden is also a place for wildlife-enthusiasts.Look for grass snakes in the lake.A snake called‘Hissing Sid'is regularly seen lying in the heat of the warm sun.
Byron's Pool
     Many stories surround Lord Byron's time as a student of Cambridge University.Arriving in 1805,he wrote a letter complaining that it was a place of"mess and drunkenness".However,it seems as though Byron did manage to pass the time pleasantly enough.I'm not just talking about the pet bear he kept in his rooms.He spent a great deal of time walking in the village.
     It is also said that on occasion Byron swam naked by moonlight in the lake,which is now known as Byron's Pool.A couple of miles past Grantchester in the south Cambridgeshire countryside,the pool is surrounded by beautiful circular paths around the fields.The cries of invisible birds make the trip a lovely experience and on the way home you can drop into the village for afternoon tea.If you don't trust me,then perhaps you'll take it from Virginia Woolf---over a century after Byron,she reportedly took a trip to swim in the same pool.
63.As mentioned in the passage,there is a small charge forA.
A.learning life drawing              
B.working with local artists
C.a(chǎn)ttending the masters'class       
D.seeing an exhibition
64."Torch Aloe"and"Venus Flytrap"areC.
A.common insects              
B.rarely-seen snakes
C.impressive plants               
D.wildlife-enthusiasts
65.We can infer from the passage that Byron seemedD.
A.to fear pet bears               
B.to finish university in 1805
C.to be a heavy drinker           
D.to like walking 
66.What is the passage mainly about?B
A.A way to become creative in art.
B.Some places for weekend break.
C.The colorful life in the countryside.
D.Unknown stories of Cambridge University.
