35. Questions 31 to 35 are based on the following passage.Lao Zi once said， “Care about what other people think and you will always be their prisoner.” People-pleasing， or seeking self-worth through others’ approval， is unproductive and an exhausting way to go through life.Why do we allow what others think of us to have so much power over how we feel about ourselves? If it’s true that you can’t please people all the time， wouldn’t it make sense to stop trying?Unfortunately， sense often isn’t driving our behavior.For social beings who desire love and belonging， wanting to be liked， and caring about the effect we have on others， is healthy and allows us to make connections.However， where we get into trouble is when our self-worth is dependent upon whether we win someone’s approval or not.This need to be liked can be traced back to when we were children and were completely dependent on others to take care of us: Small children are not just learning how to walk and communicate， they are also trying to learn how the world works.We learn about who we are and what is expected of us based on interactions with others， so， to a four-year-old， if Mommy or Daddy doesn’t like him or her， there is the danger that they will abandon them.We need to understand that when we desperately want someone to approve of us， it’s being driven by that little kid part of us that is still terrified of abandonment.As you become more capable of providing yourself with the approval you seek， your need for external validation will start to vanish， leaving you stronger， more confident， and yes， happier in your life.Imagine how much time we lose each moment we restrain our authentic selves in an effort to be liked.If we base our worth on the opinions of others， we cheat ourselves of the power to shape our experiences and embrace life not only for others but also for ourselves， because ultimately， there is no difference.So embrace the cliché (老话)and love yourself as it’s highly doubtful that you’ll regret it.What does the author advise us to do in the last paragraph?

4. 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.If two men suspected for some reason they have a common ancestor， ().

5. 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.Pawpaw festivals are organized in some states ().

5. Passage Thirty-OneAdam Smith was the first person to see the importance of the division of labor.He gave us an example of the process by which pins were made in England.“One man draws out the wire， another strengthens it， a third cuts it， a fourth points it， and a fifth gives it a head.Just to make the head requires two or three different operations.The work of making pins is divided into about eighteen different operations， which in some factories are all performed by different people， though in others the same man will sometimes perform two or three of them.”Ten men， Smith said， in this way， turned out twelve pounds of pins a day or about 4，800 pins a worker.But if all of them had worked separately and independently without division of labor， they certainly could not have made twenty pins in a day and not even one.There can be no doubt that division of labor is an efficient way of organizing work.Fewer people can make more pins.Adam Smith saw this， but he also took it for granted that division of labor is itself responsible for economic growth and development and it accounts for the difference between expanding economies and those that stand still.But division of labor adds nothing new， it only enables people to produce more of what they already have.According to the writer， which of the following is NOT true?
