2. Passage ThirtyThe Chinese have used a method called acupuncture (针灸)to help perform operations for about 4， 000 years without putting the patient to sleep.This involves inserting flexible needles into certain parts of the body.The needles are available in a number of stores in China and everyone may buy them.To learn how to use needles takes about one month of training.But to be skillful requires greater time.The person who performs the acupuncture knows how to put in the needles so the needles themselves are not painful.This person also knows where to place the needles so the patient feels no pain in the area where the operation is to be performed.In the past， a particular operation might require 25 or more needles placed in various parts of the body.But now this operation requires only 3 or 4 needles.Today， the Chinese doctors are trying to learn more about acupuncture.They are trying to develop a convincing theory to explain how the needles work in preventing pain， or why a needle in the wrist， for example， would prevent the pain in the area of the mouth.A patient who needs an operation is given a choice between having acupuncture or having one of the chemicals used for putting him to sleep.It has been estimated that over half of the patients choose acupuncture because there is no sickness after the operation whereas the chemical may make the patient sick for a few hours or a day.Which statement is NOT true of the performer of acupuncture?

5. Passage ElevenDoctors say anger can be an extremely damaging emotion， unless you learn how to deal with it.They warn that anger can lead to heart disease， stomach problems， headaches， emotional problems and breast cancer.Anger is a normal emotion that we all feel from time to time.Some people express anger openly in a calm and reasonable way.Others burst with anger， screaming and yelling.But still others keep their anger inside.They cannot or will not express it.This is called (repressing)anger.For years some doctors claim that both repressing and expressing anger can be dangerous.They say that in both situations the brain of an angry person releases the same hormones (荷尔蒙).They spend the heart rate， raise blood pressure or sugar level in the blood.As a result， the angry person feels excited and is ready to react.The violent reaction may lead to high blood pressure.However， some other doctors argue that repressing anger is more dangerous to a person’s health than expressing it.They believe that those who keep their anger inside may face a greater danger of heart disease.Most doctors agree that it is important to learn how to deal with anger.They say the first step is to admit that you are angry and recognize the real cause of the anger， then decide if the cause is serious enough to get angry about.If so， you should not express your anger immediately and try to wait until your anger has cooled down， so that you are able to express yourself calmly and reasonably.They also believe that a good way to deal with anger is to find humor in the situation that has made you angry.After all， it is much healthier to laugh than to get angry.What is the tone of this passage?

40. Questions 36 to 40 are based on the following passage.Some people have said aging is more a slide into forgetfulness than a journey towards wisdom.However， a growing body of research suggests that late-in-life learning is possible.In reality， education does an aging brain good.Throughout life， people’s brains constantly renovate themselves.In the late 1960s， British brain scientist Geoffrey Raisman spied growth in damaged brain regions of rats through an electron microscope; their brains were forging new connections.This meant brains may change every time a person learns something new.Of course， that doesn’t mean the brain isn’t affected by the effects of time.Just as height usually declines over the years， so does brain volume: Humans lose about 4 percent every decade starting in their 40s.But that reduction doesn’t necessarily make people think slower; as long as we are alive and functioning， we can alter our brains with new information and experiences.In fact， scientists now suspect accumulating novel experiences， facts， and skills can keep people’s minds more flexible.New pathways can strengthen our ever-changing mental structure， even as the brain shrinks.Conventional fixes like word puzzles and brain-training apps can contribute to mental durability.Even something as simple as taking a different route to the grocery store or going somewhere new on vacation can keep the brain healthy.A desire for new life challenges can further boost brainpower.Research about aging adults who take on new enterprises shows improved function and memory as well as a reduced risk of mental disease.Openness—a characteristic defined by curiosity and a desire for knowledge—may also help folks pass brain tests.Some folks are born with this take-in-the world attitude， but those who aren’t as genetically gifted aren’t necessarily out of luck.While genes can encourage an interest in doing new things， a 2012 study in the journal Psychology and Aging found completing reasoning tasks like puzzles and number games can enhance that desire for novel experiences， which can， in turn， refresh the brain.That’s why brain scientist Richard Kennedy says “It’s not that old dogs can’t learn new tricks.It’s that maybe old dogs don’t realize why they should.”What is the finding of the 2012 study in the journal Psychology and Aging?

A. 　Wishing to solve puzzles enhances one’s reasoning power.

B. 　Playing number games unexpectedly stimulates one’s memory.

C. 　Desiring new experiences can help to renovate the brain.

D. 　Learning new tricks should not be confined to old dogs only.

5. Passage Twenty-FourSocial change is more likely to occur in societies where there is a mixture of different kinds of people than in societies where people are similar in many ways.The simple reason for this is that there are more different ways of looking at things present in the first kind of society.There are more ideas， more disagreements in interest， and more groups and organizations with different beliefs.In addition， there is usually a greater worldly interest and greater tolerance in mixed societies.All these factors tend to promote social change by opening more areas of life to decision.In a society where people are quite similar in many ways， there are fewer occasions for people to see the need or the opportunity for change because everything seems to be the same.And although conditions may not be satisfactory， they are at least customary and undisputed.Within a society， social changes is also likely to occur more frequently and more readily in the material aspects of the culture than in the non-material， for example， in technology rather than in values; in what has been learned later in life rather than what was learned early; in the less basic and less emotional aspects of society than in their opposites; in the simple elements rather than in the complex ones; in form rather than in substance; and in elements that are acceptable to the culture rather than in strange elements.Furthermore， social change is easier if it is gradual.For example， it comes more readily in human relations on a continuous scale rather than one with sharp dichotomies (一分为二).This is one reason why change has not come more quickly to Black American as compared to other American minorities， because of the sharp difference in “appearance between them and their white counterparts”.Social change is less likely to occur in a society where people are quite similar in many ways because ().
