I am a 18﹣year﹣old Chinese girl． I've been learning English in a few years． To my joy， with the help of Linda， my pen pal in American， I'm getting more and more interesting in English． Linda， like many girls， are kind and lovely． Although her English isn't easy to understand it， we enjoy write to each other and we usually talk a lot about our school activities． By communicating， we also realize that Chinese culture or American culture are so differently． I am determined to work hard improve my English so that I can introduce some traditional Chinese festivals to her．

"Cultural difference" is a broad term． However， when living in America， you can experience the difference in culture when you compare various details of people's lives． 1. By seeing how American students treat their weekends in a New England boarding school， I have found some differences between American culture and my own．
If you’re picturing American boarding school weekend life as partying all the time， your description might be inaccurate﹣ at least at my school． Influenced by the diligent working culture in New England， a Saturday in Groton follows a half﹣weekday schedule． 2.There are often sports matches in the afternoon ﹣ either home or away﹣ and if not， there are still sports practices and rehearsals for drama and dance． 3.There isn't a chance to stay up all night on Friday night to party．
4.After a long week of school， everyone longs for entertainment． Back in China， I used to go to dinners or movies with my friends on weekend nights， and it's the same in Groton． Although it lies in a suburban area， there are always Saturday night dinner trips to restaurants in town， and sometimes the Student Activity Center even organizes movie trips to a mall nearby．
5. Unlike in China， where I had to spend my whole Sunday taking extra classes and doing homework， American students don't usually have extra classes and prefer to save homework for study hall in the evening． On Sunday mornings， I usually sleep until 11， have a light brunch， then hang out with my friends and have fun．
A.Sunday is a day for recovery．
B.Saturday night is the time for fun．
C.Therefore， looking at the weekend is interesting．
D.Classes on Sunday are more interesting in the US．
E.So basically everyone is busy all day on Saturday．
F.Classes start at eight in the morning and end at noon．
G.Students could spend half a day preparing for the parties．
The Federal Reserve System， also simply known as the Fed， is the central banking system of the USA． It is different from the usual central banks． The Fed performs the functions of the central bank but it isn't a slave to the federal government． This unique banking system was so designed just to prevent the risk that the federal government might take advantage of the central bank to stop the normal financial activities．
The Fed was established in 1913． It is composed of the Federal Reserve Banks located around the United States． It's governed by seven executive members whose term is as long as 1﹣years． They are appointed by the president， but the president doesn't have the right to dismiss them． To alleviate the president's influence upon the Fed， the president is only allowed to appoint two of the committee members in his four﹣year term．
Federal Reserve Banks are non﹣profit private hanks． They're organizations to carry out money policies． Their responsibilities are to issue money， manage the state treasury， adjust the currency circulation， see the operation of commercial banks and settle bills． Commercial hanks must hold stock in Federal Reserve Banks and keep some amount of money as reserve in one of the Federal Reserve Banks just to prevent the sponsors run away with all the bank savings．
The Federal Open Market Committee is its core managing organization． It's made up of twelve members， including seven executive members of the Fed． Chairman of New York Federal Bank and other four chairman of the Ⅱ Federal Reserve Banks in turn． Their voting result determines the policy trend．
The Federal Open Market Committee holds 8 meetings every year． If the economy is heated the Federal Open Market Committee decides to sell national debt and get in the dollars． In this way the loan interest rate will go up． Otherwise， it chooses to buy in national debt and release more dollars onto the market．
1.Why was the Fed designed to be independent of the federal government？
A.Just to give support to the government．
B.Just to cooperate with the government．
C.Just to limit the government's power．
D.Just to stop financial crisis in advance．
2.What does the underlined word "alleviate" in the second paragraph mean？
A.Promote．
B.Reduce．
C.Present．
D.Emphasize．
3.Which presents the basic function of Federal Reserve Banks？
A.Conducting monetary policies．
B.Keeping money for depositors．
C.Lending money to target users．
D.Monitoring the Fed's operation．
4.What will the Fed do if the economy turns down according to the passage？
A.To increase interest rates．
B.To buy in the national debt．
C.To raise the rate of reserve．
D.To sell more national debt．
Recently researchers at the University of Zurich are adding a new member to the drone （无人机） family． Unlike most drones whose application is to make selfies （自拍） or transport something， this drone was built with first aid workers and rescue efforts in mind． Disaster sites are rarely of logical shapes and sizes． So having a drone that could change its shape and size to fit through tight spaces on the fly could prove extremely valuable．
As is often the case in experimental robotic projects， researchers met some technical shortcomings at the beginning． The airplane mode of the existing aircraft， such as passenger planes helicopters and the common drones， couldn't meet the demand of different environmental features． Eventually， they turned to animals for inspiration﹣specifically how some birds can fold their wings to fly through narrow passages．
What makes it distinguishing is that when faced with a narrow passage， it can change into an H shape． Or it can shrink itself into an O shape， arms folded into its body． And if that isn't enough it can also transform into a T shape， allowing an on﹣board camera on the central frame to， get as close as possible to its focal object． While the working concept model is impressive， the researchers aren't done with the folding drone yet They want to improve the structure of the drone so that it can fully fold in three dimensions （维度）， offering even mare shapes， And they want to create full auto operation﹣a drone that looks at the changing land features in， for example， an apartment building partly destroyed by an earthquake and changes its shape to meet is current needs． Researchers say their final goal is to give the drowse a high﹣level instruction such as "enter that building， inspect every mom and come back" and let it figure out by itself how to do it．Therefore， it's reasonable to hope the new drone will play an important supporting role in disaster rescue．
1.What was the new done initially designed to do？
A.To provide disaster relief．
B.To take air photography．
C.To convey a heavy load．
D.To send a message signal．
2.Where did the researchers get the inspiration？
A.From passenger planes．
B.From small helicopters．
C.From flying creatures．
D.From common drones．
3.What is the drone's biggest advantage？
A.It has a unique shape．
B.It can change its shape．
C.Its arms are flexible．
D.It can reach its target．
4.Which can be the best title for the passage？
A.A Drone： To Fold and Unfold in the Sky．
B.A Drone： To Transport Goods in the Future．
C.A Drone： To Make Selfies for Fun．
D.A Drone： To Make a Difference in Rescue．
