36. 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 do some people think of aging adults?

A、 Their wisdom grows as time goes by.

B、 Their memory gradually deteriorates.

C、 They can benefit from late-in-life learning.

D、 They are likely to have mental health issues.

3. 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.The best way to deal with anger is ().

1. Passage Thirty-TwoHave you ever heard of a pawpaw (木瓜)? If not, do not feel bad.Many Americans do not know of the fruit, although it is native to the U.S.Once, however, it was one of the most popular fruits in North America.Happily, those who love the pawpaw are trying to return it to its former position in American foods.A pawpaw is a tropical fruit that used to be grown along the East Coast from New York to Florida and all over the eastern U.S.At one time, it could be found as far west as Nebraska.The pawpaw was an important food for Native Americans and even early European settlers.Pawpaws reportedly were a favorite treat of George Washington, the first U.S.president, who especially liked them cold.Thomas Jefferson, the third U.S.president, was also a fan of the fruit.He planted pawpaws at his home in Virginia.He also sent pawpaw seeds to his friends in France.American explorers Lewis and Clark wrote in their journals about the pawpaw.The pawpaw is difficult to be sold commercially.The fruit requires a very special environment—low, wet areas that sometimes flood.It has a very short harvest season, from two to three weeks in September and October.In addition, the fruit is good to eat for only two to three days after harvesting.This makes it hard to sell anywhere distant from the pawpaw tree it comes from.Planters are again growing pawpaw trees and harvesting the fruit.In several states farmers have organized “pawpaw festivals” to reintroduce people to food.At such a festival in Maryland recently, farmers displayed different products made with pawpaws, like pawpaw jams, pies, ice-cream and beer.Many American people do not know that the pawpaw ().

2. Passage Thirty-ThreeWe all know that DNA has the ability to identify individuals but, because it is inherited, there are also regions of the DNA strand which can relate an individual to his or her family (immediate and extended), tribal group and even an entire population.Molecular Genealogy (宗谱学)can use this unique identification provided by the genetic markers to link people together into family trees.Pedigrees (家谱)based on such genetic markers can mean a breakthrough for family trees where information is incomplete or missing due to adoption, illegitimacy or lack of records.There are many communities and populations which have lost precious records due to tragic events such as the fire in the Irish courts during Civil War in 1921 or American slaves for whom many records were never kept in the first place.The main objective of the Molecular Genealogy Research Group is to build a database containing over 100,000 DNA samples from individuals all over the world.These individuals will have provided a pedigree chart of at least four generations and a small blood sample.Once the database has enough samples to represent the world genetic make-up, it will eventually help in solving many issues regarding genealogies that could not be done by relying only on traditional written records.Theoretically, any individual will someday be able to trace his or her family origins through this database.In the meantime, as the database is being created, molecular genealogy can already verify possible or suspected relationships between individuals.“For example, if two men sharing the same last name believe that they are related, but no written record proves this relationship, we can verify this possibility by collecting a sample of DNA from both and looking for common markers (in this case we can look primarily at the Y chromosome (染色体),” explains Ugo Perego, a member of the BYU Molecular Genealogy research team.The possible research of family trees is based on the fact that ().
