An Oil for Life
olive
Maria Alcala of Madrid speaks for many Mediterranean people when she says that"a meal without olive oil would be a bore．"No one knows when the Mediterranean civilizations fell in love with olives．That occurred before recorded history．However，there is evidence that the cultivation （种植） of olive trees began in countries around the Mediterranean Sea in approximately 4000B．C．，and 2000years after that people in the eastern Mediterranean area began to produce oil from olives．The Mediterranean still accounts for 99percent of all world olive oil production．
From ancient times until today，the basic process of producing the oil is the same．First，whole olives are pressed hard into pieces．Then，the liquid is separated from the solids．After that，the valuable oil is separated from the water．
Many olive growers make their ancient traditions continue and still harvest the olives by hand．"We harvest in the traditional way，"says Don Celso，an olive farmer from Tuscany，Italy．"It would be less expensive to do it with machines，but it's more a social thing．Twenty people come to help with the harvest，and we pay them in oil．"
Olive oil has had a variety of uses through its long history．In ancient times，olive oil was used as money and as medicine．It was even used during war-heated up and dropped down on attackers．It is still used in religious ceremonies．It is great for protecting the freshness of fish and cheese．There are even olive oil lamp and olive oil soaps．
One important study shows that Mediterranean people have the lowest rate of heart disease among Western nations．This is partly associated with their frequent use of olive oil．Other studies show that food cooked in olive oil is healthier，and that eating olive oil twice a day reduces women's risk of getting breast cancer．The world is beginning to understand its benefits，and olive oil is no longer an unusual sight at dinner tables outside the Mediterranean area．The olive oil producing countries now sell large amounts of olive oil to countries in Europe，Asia，Africa，and North and South America．
Olive oil improves the lives of people everywhere．Its benefits，recently confirmed by science，were already understood in ancient times．Mediterranean people are happy to share their secret with the world．

48．Which step occurs first in olive oil production？D
A．Drying the olives under the sun．
B．Separating the oil from the water．
C．Separating the liquid from the solids．
D．Pressing the whole olives into pieces．
49．Which use of olive oil is NOT mentioned in the passage？A
A．Paint．
B．Medicine．
C．Money．
D．Soap．
50．Why does the author include information about several studies of olive oil？C
A．To give reasons why olive oil is similar to medicine．
B．To show how the biology of Mediterranean people is special．
C．To explain the growing interest in olive oil around the world．
D．To prove that olive oil is more important for women than for men．
51．What is the passage mainly about？B
A．Discussing olive oil production outside the Mediterranean area．
B．Explaining the history，production，benefits，and use of olive oil．
C．Showing why olive oil is produced around the Mediterranean Sea．
D．Comparing Mediterranean olive oil with that produced in other places．

Computers have beaten human world champions at chess and, earlier this year, the board game Go. So far, though, they have struggled at the card table. So we challenged one AI to a game.

Why is poker(扑克)so difficult? Chess and Go are “information complete” games where all players can see all the relevant information. In poker, other players’ cards are hidden, making it an “information incomplete” game. Players have to guess opponents’ hands from their actions----tricky for computers. Poker has become a new benchmark for AI research. Solving poker could lead to many breakthroughs, from cyber security to driverless cars.

Scientists believe it is only a matter of time before AI once again vanquishes humans, hence our human-machine match comes up in a game of Texas Hold’s Em Limit Poker. The AI was developed by Johannes Heinrich, researcher studying machine learning at UCL. It combines two techniques: neural(神经的)networks and reinforcement learning(强化学习).

Neural networks, to some degree, copy the structure of human brains: their processors are highly interconnected and work at the same time to solve problems. They are good at spotting patterns in huge amounts of data. Reinforcement learning is when a machine, given a task, carries it out, learning from mistakes it makes. In this case, it means playing poker against itself billions of times to get better.

Mr Heinrich told Sky News: “Today we are presenting a new procedure that has learned in a different way, more similar to how humans learn. In particular, it is able to learn abstract patterns, represented by its neural network, which allow it to deal with new and unseen situations.”

After two hours of quite defensive play, from the computer at least, we called it a draw.

1.Why can’t the computer beat humans at the poker game?

A. Because humans are cleverer than the computer

B. Because humans practice playing the poker game every day

C. Because the computer can’t know the other players’ cards completely

D. Because the computer can’t learn the regular rules of the poker game

2.What does the underlined word “vanquishes” in Paragraph 3 mean?

A. Leaves B. Defeats C. Cheats D. Serves

3.What do we know about the reinforcement learning of AI?

A. It solves problems correctly every time

B. It is the same as the learning of humans

C. It learns from the mistakes appearing in a task

D. It is more developed than the studying ways of humans

4.What can be inferred from the text?

A. The new procedure of AI has some features of humans

B. Computers are stronger than humans in every aspect

C. Humans will beat computers at playing poker forever

D. Scientists feel unhappy about the result of the poker game
