2．After almost an entire year of saving from shopping and vacationing，you find the numbers reflected by your bank account meet your heat's desire．Now the most important question comes what to do with the earnings？Should you fulfill dreams of the present，or keep saving it for a rainy day？
Our elders always try to teach us the value of money and its uncertainty．One may be on a winning situation now，but it will not always be so．One will have days when there will be no sunshine but only rain，and their luck will hide behind those thick grey clouds．Save for those rainy days，they say．Do not spend too much，live within a budget，stay away from credit no matter how small and save for the future．Since the very first time we earn our own money from a summer job or earn our first salary，the lessons start．
In fact，the pocket money that we receive when we are children starts the process of learning how to best manage one's manage one's money．Future，future，future，that's all they talk about，but what about the present？What about our current desires，wants and needs？Wasn't our present once our future？
One day when I have enough money，I will buy myself a car．One day my luck will shine．One day I will have enough money to travel the world．Then，once we do earn enough money from saving，tomorrow's plans start shadowing our present ones．
However，is it wise to keep living for that future？Will we still enjoy or even be able to backpack in our 50s？What will be the use of those professional cameras when pains take over our joints and our mind grows dull？Will our liver be able too handle the meat and alcohol in our advanced age？What if our life ends suddenly？How will we ever enjoy our present if we are constantly living for the future？
I say enjoy the most comfort but also keep enough for your necessities，and stay happy with your present but with a plan for the foreseeable future．Beyond that，life is not in our control and we shouldn't worry about the unseen．Life is for the living，so live it wisely．

56．The underlined"a rainy day"in the first paragraph has the same meaning asD．
A．the background of the story is set on a rainy day
B．driving fast on a rainy day may lead to accidents
C．it is crazy of him to suggest a picnic on such a rainy day
D．he always puts aside his pocket money for a rainy day
57．The questions in the fifth paragraph suggest thatC
A．the author insists that w should live for the future
B．the author doubts the meaning of living in the world
C．the author believes that enjoying our present is very important
D．the author is not sure whether we should save money or spend it
58．The statement that the author may agree with is thatC
A．we should live happily regardless of others'words
B．we should care more about future and shouldn't just live today
C．we should live happily at present and be prepared for the future

19．Terrafugia Inc．said Monday that its new flying car has completed its first flight，bringing the company closer to its goal of selling the flying car within the next year．The vehicle---named the Transition-has two seats and wings that fold up so it can be driven like a car．The Transition，which flew at 1，400feet for eight minutes last month，can reach around 70 miles per hour on the road and 115in the flies using a 23-gallon tank of gas and bums 5 gallons per hour in the air．On the ground，it gets 35miles per gallon．
Around 100 people have already put down a﹩10，000 deposit to get a Transition when they go on sale，and those numbers will likely rise after Terrafugia introduces the Transition to the public later this week at the New York Auto Show．But don't expect it to show up in too many driveways．It's expected to cost﹩279，000．And it won't help if you're stuck in traffic．The car needs a runway．
Inventors have been trying to make flying cars since the 1930s，according to Robert Mann，an airline industry expert．But Mann thinks Terrafugia has come closer than anyone to making the flying car a reality．The government has already permitted the company to use special materials to make it easier for the vehicle to fly．The Transition is now going through crash tests to make sure it meets federal safety standards．
Mann said Terrafugia was helped by the Federal Aviation Administration's decision five years ago to create a separate set of standards for light sport aircraft，which are lower than those pilots of larger planes Terrafugia says an owner would need to pass a test and complete 20hours of flying time to be able to fly the Transition，a requirement pilots would find relatively easy to meet．

28．What is the first paragraph mainly about？A
A．The basic data of the Transition．
B．The advantages of flying cars．
C．The potential market for flying cars．
D．The designers of the Transition．
29．Why is the Transition unlikely to show up in too many driveways？C
A．It causes traffic jams．
B．It is difficult to operate．
C．It is very expensive．
D．It bums too much fuel．
30．What is the government's attitude to the development of the flying car？B
A．Cautious．
B．Favorable．
C．Ambiguous．
D．Disapproving．
31．What is the best title for the text？D
A．Flying Car at Auto Show           B．The Transition's Fist Flight
C．Pilots'Dream Coming True         D．Flying Car Closer to Reality．
