For many years, scientists couldn't figure out how atoms and molecules on the Earth combined to make living things. Plants, fish, dinosaurs, and people are made of atoms and molecules, but they are put together in a more complicated way than the molecules in the primitive ocean. What's more, living things have energy and can reproduce, while the chemicals on the Earth 4 billion years ago were lifeless.
  After years of study, scientists figured out that living things, including human bodies, are basically made of amino acids and nucleotide bases. These are molecules with millions of hydrogen, carbon, nitrogen, and oxygen atoms. How could such complicated molecules have been formed in the primitive soup? Scientists were stumped.
  Then, in 1953, two scientists named Harold Urey and Stanley L. Miller did a very simple experiment to find out what had happened on the Primitive Earth. They set up some tubes and bottles in a closed loop, and put in some of the same gases that were present in the atmosphere 4 billion years ago: water vapor, ammonia, carbon dioxide, methane, and hydrogen.
  Then they shot an electric spark through the gases to simulate bolts of lightning on the ancient Earth, circulated the gases through some water, sent them back for more sparks, and so on. After seven days, the water that the gases had been bubbling through had turned brown. Some new chemicals were dissolved in it. When Miller and Urey analyzed the liquid, they found that it contained amino acids-the very kind of molecules found in all living things.

“Then you should __44__ !It's obvious that your wallet is a(an) __45__ one, so don't load it too heavily,” said the Goddess Fortune.

The excited beggar could hardly __46__ to have gold. He quickly opened his wallet, and a __47__ of yellow coins was poured into it. The wallet grew heavier and heavier.

“Is that enough? Isn't it cracking?” asked Fortune.

“Never __48__ .It's still strong enough now.”answered the beggar.

The wallet was filled with so many coins that the beggar's hands began to __49__. “Ah, if only the golden stream would __50__ forever! Just a little more,” said the beggar, “__51__ just a handful or two.”

“There! It's full. The wallet will __52__ .” warned the Goddess, but the beggar requested, “It will __53__ a little more, just a little more.”

The cartoon is jokingly updating Shylock, a leading figure from William Shakespeare’s classic play The Merchant of Venice, to fit into the new age of the Internet. In the play, the Christian merchant Antonio has borrowed money from Shylock ,who is Jewish. Because of their religion Jews like Shylock have been regarded as low and worthless and badly mistreated by the noble-styled gentleman Antonio and his friends, who at that time contained the very Christian society of Venice and indeed all Europe .On account of the conflict between members of the two religions, despite their being willing to enter into business deals, there is little love or friendship between the two.

Shylock agrees to lend Antonio the money but as part of the written agreement he insist that should Antonio fail to repay him on time he must cut a pound of his own flesh from his body and present it to Shylock. This of course would kill him but nonetheless Antonio agrees. In the end, Antonio’s business fails as the ships carrying his goods sink (Antonio is truly a gentlemen but not much of a businessman),and Antonio has to be forced to threateningly face Shylock and his demands.

In the cartoon, Shylock is a merchant who operates, as many businessmen do today, on the Internet. His website, www.poundoffflesh, com. is probably where Antonio would log on to get terms of his loan. The humor lies in the contrast between the very modern business technology and the very old-fashioned costume Shylock is wearing.

1.We may learn from the text that the writer of the article is for the purpose of ____.

A. grandly advertising the new cartoon to the audience

B. warning us not to borrow money from the merchants like Shylock

C. simply introducing a new cartoon on the net to the public

D. telling readers to be sincere and honest when you deal with your friends

2.The underlined word “contain” probably means ____.

A. control  B. cover       C .include      D. create

3.You will find it very funny when you see the cartoon that ____.

A. large amounts of money go into Shylock’s cashbox

B. Antonio doesn’t suffer from his flesh being cut off his body

C. many famous actors and actress are invited to perform the updated classic play

D. all the characters in the cartoon are not in today’s clothes though they do nowaday business

4.What would be the best title for the text?

A. The E-merchant of Venice

B. Business between Shylock and Antonio

C. Never Borrow Money from Shylock

D. Sow the Wind and Reap(gain) the Whirlwind
