An average 30-year-old person who has eaten three meals a day since birth has eaten more than 30,000 meals to date.Even if you’ve only eaten half that much you have to admit this：you’ve let some of that breakfast，lunch or dinner go to waste.And it turns out we're all to blame for this shaming fact：30% of all food produced in the world each year is wasted or lost.That’s about 1.3 billion tons，according to a new report by
the U．N.Food and Agriculture Organization.
That's the weight of more than 8.6 million full-grown blue whales，the largest creatures on earth.That's the weight of more than 2.3 million Airbus A380s，the largest planes in existence.That's as if each person in China，the world's most populous country with more than 1.3 billion people，had one ton mass of food they could just throw into the dustbin.It's almost unfathomable，isn't it?
Setting aside that big number，we find the people with the most money are the ones who waste the most.Per capita (人均)，European and North American countries waste between 95 and 115 kilograms of food.Sub-Saharan African，South Asian and Southeast Asian countries waste much，much less－between 6 and 11 kilograms per person.
Here's another statistic：all the food that the world's richest countries waste is about equal to all the food that subSaharan Africa produces.The numbers：222 million tons and 230 million tons，respectively (分别地)．Basically，the wasted food of the rich could feed much of the African continent.And these numbers come as we've just been reporting about rising food prices around the world in the past week.
And my own personal tip：if I eat at a restaurant and can't finish it all，I ask for a doggie bag.I used to be a waiter years ago and will never forget the amounts of food I saw left on the table after the bill was paid.There's no reason to waste food.It's up to all of us to use our common sense to eat and shop just a bit more wisely.
61．According to the U．N.Food and Agriculture Organization，how much food do people produce each year in the world?
A．About 3.3 billion tons. B．About 3.9 billion tons. C．About 4.3 billion tons. D．About 5.6 billion tons.
62．What does the underlined word “ unfathomable” in Paragraph 2 mean? A．Possible to imagine. B．Impossible to change. C．Impossible to understand. D．Possible to understand.
63．It can be learned that the food the rich waste can support________. A．half the people in Europe B．most people of America C．most people of Asia D．most people of Africa
64．The author gave his personal tip based on the fact that________.

C．he once worked in a restaurant D．the price of food is very high 65．What is the purpose of this article?
A．To show the author's opinion of food. B．To let us live more wisely and not waste food.
C．To show the amount of wasted food a year. D．To ask the richest countries to help African people.

You could fill the sky with all the ideas people have had for flying cars，or what Carl Dietrich calls“flying-driving vehicles”．Carl Dietrich said，“Since the turn of the 20th century，there have been hundreds of published concepts for flying-driving vehicles.And some of them have actually been built and flown.But at this point the Transition is the closest to actually getting to the marketplace.”
Carl Dietrich heads a company in Massachusetts called Terrafugia.He said，“Terrafugia is developing the Transition street-legal airplane，which many people have characterized as the first practical flying car.”
Carl Dietrich says the Transition Roadable Aircraft easily changes to a car.He said，“It takes about twenty seconds.It's like puffing the top down on a convertible (敞篷车)；only instead of folding up your roof，we're folding up our wings and we're transferring power from a propeller (螺旋桨) to the wheels for driving on the ground.”
Development began in 2006，and the first road and flight tests took place in 2009.The Transition had to meet federal safety standards for cars and aircrafts.Last year the Federal Aviation Administration agreed to let it weigh more than other light sport aircrafts.But even fully loaded，says Mr.Dietrich，it just weighs about half as much as an average car.
Carl Dietrich says the aircraft can climb to more than three thousand meters.It can carry two people at speeds over one hundred and sixty kilometers an hour in the
air.And on the ground it can drive at highway speeds，around one hundred and thirteen kilometers an hour.The plane needs an airport for take-offs and landings，which can be a problem if the buyer doesn't have a private airport.But it uses automotive gasoline. The company expects to complete the building process for its flying cars within the next few months.Then it will begin a year-long testing program.Terrafugia expects the Transition to reach the market by the end of 2012，at a price of around two hundred and fifty thousand dollars.
66．According to Carl Dietrich，Terrafugia is trying to________.
A．develop cars to increase their running speeds B．publish concepts for flying-driving vehicles
C．produce practical flying cars D．prove that cars can fly 67．Paragraph 3 shows that the Transition Roadable Aircraft________. A．looks smaller than a normal car B．doesn't have a roof like a normal car C．will be very difficult to operate at first D．can be used both in the sky and on the ground
68．What might be a problem that the Transition Roadable Aircraft will face? A．It can only carry the driver.
B．There will not be proper gasoline for it C．It will weigh too much to fly in the sky.
D．There will not be enough places for its take-offs and landings. 69．The last paragraph shows that________.
A．flying cars will not be in wide use B．flying cars will be put into use quite soon C．the future market of the flying cars is not bright D．flying cars will still be a dream for a long time
70．What's the main idea of this passage?
A．Flying cars will replace airplanes. B．Flying cars move closer to reality. C．Flying cars are ready for the market. D．Flying cars have been built before.

Before the opening of the Cape Cod Canal in 1914，the only way ships could leave Boston was on a route around Race Point－the northern tip of Cape Cod.However，navigation during the 18th century was a nightmare，because the floating cross current
(交叉气流) around Race Point caused countless accidents.So building a lighthouse to lighten the place was very necessary.
As early as 1808，the people of Provincetown requested a lighthouse on Race Point，but it took Congress eight years to react when they finally paid $ 8,000 on April 27,1816 to build a lighthouse－Race Point Light，which was located in the town of Provincetown，Massachusetts.It was first built of stone 25 feet high with no foundation and its light was 30 feet above the sea.It was equipped with one of the nation's earliest revolving lights.
Actually，there were two other lighthouses on Cape Cod，but they were hit by a storm in October 1841.In the following year，Race Point Light was examined by I．W.P.Lewis，who realized the light's importance.He said，“The light should be useful to all ships leaving Boston.However，its illuminating power is so weak that people would hardly be able to differentiate it from the lights set on the ships which stay in the bay，or close by.It hasn't played its role as a lighthouse well.”
The result was that old lighthouse was destroyed and a new iron lighthouse with a proper foundation was put up to take its place.The new lighthouse was 45 feet high.Although the original keeper's house was in good repair，it was destroyed too，and a new one was built.Today the lighthouse has been automated(自动化)and Race Point Light is still an active aid to navigation.
You can park at Race Point Beach and walk about 45 minutes to the lighthouse.Sunset at Race Point Light is one of the Cape Cod's most popular scenes.And at times whales can be seen in the lighthouse.For reservations to stay one night in the keeper's house at Race Point call (508)487－9930.
71．The underlined word “illuminating” in Paragraph 3 probably means________. A．preventing accidents B．cooling the air C．providing light D．predicting weather
72．Why was the original Race Point Light replaced by a new one?
A．It was too old to repair properly. B．It hadn't done a good job in helping the passing ships.
C．It was destroyed in a storm in October 1841. D．It wasn't high enough and had no foundation.
