4. 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.It is difficult to sell the pawpaw on a large scale for the following reasons EXCEPT that the fruit ().

1. Passage TenNowadays， children heavily cling to digital devices such as computers and smart phones.Some spend up to six hours a day on their digital devices.They can be playing games online with people elsewhere， updating their status on social media， texting friends， or looking for the latest apps to download to their computers or smart phones.This worried Martin Strott.He is the headmaster of the Old Hall School in Wellington， England.He was so concerned that he challenged his students to take part in a week of (“digital detox”)， a program to reduce their reliance on digital devices.Mr.Strott told the local newspaper， the Shropshire Star， that too much screen time would affect the development of their social skills.At another interview with a magazine， he mentioned that this over-reliance on digital devices “takes away family time and reduces their chances of face-to-face communication”.The parents are happy with the program.But what about the children? Nine-year-old Fred usually spends around two hours on his digital devices at home after school and around 12 hours on weekends.For him， the digital detox experience was “really hard”.He said that he had been engaged in many interesting outdoor activities organized by the headmaster， but still missed his phone and online games.The idea of keeping children away from their digital devices for a while to prevent too much dependence on them is not particularly new.There have been similar practices in the United States.But are they effective in the long run? According to Mr.Strott， even if kids go back to their digital devices， the hope is that at least they will think about how they will use their time.According to Paragraph 1， what would children do when they cling to their digital devices?
