3. 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.To learn how to use the needles， it takes a person ().

3. 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.George Washington and Thomas Jefferson are mentioned in paragraph 3 as ().

1. Passage SixteenJustin was always prepared.His motto was “Never throw anything out， you never know when it might come in handy.” His bedroom was so full of flat bicycle tires， bent tennis rackets， deflated basketballs， and games with missing pieces that you could barely get in the door.His parents pleaded him to clean out his room.“What use is a fish tank with a hole in the bottom?” his father asked.But Justin simply smiled and repeated his motto， “Never throw anything out， you never know when it might come in handy.”When Justin was away from home， he always carried his blue backpack.He liked to think of it as a smaller version of his bedroom——a place to store the many objects that he collected.It was so worn and stretched that it hardly resembled a backpack anymore.It was full of the kind of things that seemed unimportant， but when used with a little imagination， might come in handy.Justin had earned a reputation for figuring things out and getting people out of otherwise hopeless situations.Many of his classmates and neighbors sought him out when they needed help with a problem.On the first day of school， his friend Kenny， came looking for Justin.“Do you think you have something in your bag that could help me remember my locker combination?” he asked.“I lost the paper it was written on.I have science class in two minutes and if I’m late on the first day it’ll make me look bad for the rest of the year.” Kenny looked genuinely worried.“Relax，” Justin said， taking his backpack off and opened it.“Remember how you borrowed my notebook in homeroom to write the code down? Well， I know how we can recover what you wrote.”He took the notebook and a soft lead pencil out of his bag.The page that Kenny had written on had left faint indentations (旧凹痕)on another page in the notebook.Justin held the pencil on its side and rubbed it lightly over the indentations.Slowly but surely the numbers of the locker combination appeared in white， set off by the gray pencil rubbings.“That’s amazing!” Kenny said.“I owe you one.” And he dashed off to open his locker.Why is Justin’s room such a mess?
