People in the US can now carry an artificial intelligence (AI) around in their pocket, where it waits patiently to be told what to do.

Siri, an iPhone application that understands spoken commands and uses the web to carry them out,is a byproduct from a US military project to develop an artificially intelligent assistant.

Many people's experience of a "virtual assistant" may be limited to Microsoft's annoying classic Mr. Clippy. But in the week we spent together, my AI assistant has performed admirably in finding me restaurants, or the location of the nearest coffee shop. It wasn't even stumped when I asked "do I need my umbrella today?" coming straight back with the local weather forecast.

A typical command might be: "Reserve a table for two at a good French restaurant in San Francisco." Siri responds by presenting a list of top-rated restaurants that can be booked on OpenTable.com. If you say which time you want, it can book you a table without your lifting a finger.

In some ways Siri is just a fancy front-end to the 35 sites it can connect to, from taxi booking sites to movie review databases. But what's new is the way it can interpret the intentions of its master or mistress and use those sites to put them into action.

Doing that requires the ability to actually understand the meaning of words you use, not just passing on keywords blindly, says Siri co-founder Adam Cheyer.

"Book a four-star restaurant in Boston seems pretty straightforward," says Cheyer, "until you realise that Book is a city in the US, and Star is also a city in the US, and there are 13 Bostons, and Star is also the name of a restaurant."

To cut through what Cheyer calls the "combined explosion of interpretations", Siri uses your location, and the history of the commands you've given. It knows that "book" is most likely a command verb, unless you happen to be near the city of Book.

Siri attaches probabilities to the interpretation of each word and cross-reference(参照) with your location and other data, some of which you must provide yourself.

According to the passage, Siri is most probably ______.

A.still at its experimental stage

B.very popular with iPhone users

C.a US military assistant software

D.an artificial intelligence software

阅读理解。
The modern age is an age of electricity. People are so used to electric lights, radio, televisions, and

telephones that it is hard to imagine what life would be like without them. When there is a power failure,

people grope about in flickering candlelight, cars hesitate in the streets because there are no traffic lights

to guide them, and food spoils in silent refrigerators.

Yet, people began to understand how electricity works only a little more than two centuries ago. Nature

has apparently been experimenting in this field for million of years. Scientists are discovering more and more

that the living world may hold many interesting secrets of electricity that could benefit humanity.

All living cells send out tiny pulses of electricity. As the heart beats, it sends out pulses of record; they

form an electrocardiogram, which a doctor can study to determine how well the heart is working. The brain,

too, sends our brain waves of electricity, which can be recorded in an electroencephalogram. The electric

currents generated by most living cells are extremely small,often so small that sensitive instruments are needed

to record them. But in some animals, certain muscle cells have become so specialized as electrical generators

that they do not work as muscle cells at all. When large numbers of these cells are linked together, the effects

can be astonishing.

The electric eel is an amazing storage battery. It can send a jolt of as much as eight hundred volts of

electricity through the water in which it lives. (An electric house current is only one hundred and twenty volts,

but two hundred and twenty volts in China.) As many as four-fifths of all the cells in the electric eel's body are

specialized for generating electricity, and the strength of the shock it can deliver corresponds roughly to length

of its body.

1. Electricity was invented ______.

[    ]

A. when man had no candles

B. about 200 years ago

C. to be operating computers

D. by Thomse Edison

2. The following things can send out pulses of electricity except ______.

[    ]

A. electric eels and human hearts

B. Electrical generators and animal muscle

C. Stones and dry wood

D. human brain and living cells

3. The electric current send out by an eel can be ______.

[    ]

A. as much as 800 volts

B. about one hundred and twenty volts

C. as high as the house current in China

D. stored in the water where it lives

4. From this shot passage we can infer ______.

[    ]

A. the shorter an eel is, the stronger electricity it produces

B. we can always feel the electricity produced by living cells

C. human beings get their knowledge about electricity from nature

D. people learn about electricity from eels
