题目内容

A camera and a computer can “see” something that perhaps millions of pairs of eyes failed to see for 480 years: the Mona Lisa’s necklace. The discovery about the famous painting was made by an American physicist.
The Mona Lisa, painted by the Italian, Leonardo da Vinci, has been on show for many years in Paris. Now a row of white spots on the neck have been “seen”. They are said to be the remains (痕迹) of a necklace which the artist later painted over.
The painting will be examined further by using infrared scanning (红外线扫描) techniques. Laser (激光) technology can be used to show what lies directly under the surface of the finished work, too. This will help us to understand how the artist drew the picture: Did he begin with a quick-made drawing or have second thoughts as he painted the picture?
This kind of knowledge will show us the famous artist at work. It may also help to explain Mona Lisa’s smile, which has puzzled art lovers for centuries.
【小题1】This passage is mainly about ______.

A．the famous artist Leonardo da Vinci

B．an American physicist’s discovery

C．further researches on the Mona Lisa

D．The uses of modern technology

　　For years it has been possible to set up cameras to take pictures of cars as they speed along highways, jump lights or drive too fast down the street.

　　However, even if the pictures are taken automatically(自动地), someone still has to do all the paperwork of sending out fines. But now a British company called EEV has come up with a computerized video system that can do it all automatically. They suggest that all number plates have a bar code as well as the usual number. The bar codes are just stripes of lines like those you see on food packets but bigger. EEV's high speed video camera system can read a bar-coded number plate even if the car is doing over l00 miles per hour. The computer controlling the system could then use the information from the bar code to find out the name and address of the driver( from the car records), print out the fine and sent it off automatically. The inventors also suggest that the system should watch traffic to help catch stolen cats.

　　The new electronic system could be watching everyone that passes the cameras ! Many people find the idea that “big brother is watching you”is more of a worry than a few motorists getting away with driving too fast. Besides, some people will be very unhappy to realize that with the new system the police should find out where a particular car has been.

1．The best title for the article can be ________.

[　　]

A．People Who Drive Too Fast

B．Stop People from Driving Too Fast

D．A New Computerized System for Motoring Breaking Law

[　　]

A．take pictures of cars on highways

[　　]

A．car number plates

B．car speeding records

C．bar code numbers on number plates

D．print-out fines

4．An additional purpose of the new system is that it could ________.

[　　]

A．help catch stolen cars

B．add code numbers

C．watch everyone who drives too fast

D．print out bar codes automatically

5．“‘Big brother is watching you’ is more of a worry than… ”means that many people ________.

[　　]

A．are more worried about fast-driving motorists than being watched on

B．find “big brothers”more worrying than motorists

     The iPad is an Apple tablet computer. The device sits somewhere between a laptop and a
smart phone, according to Apple's chief executive, Steven P. Jobs, and does certain things better
than both of them, like surfing the Web, reading e-books and playing videos. The iPad went on
sale on April 3, 2010, and Apple said it had shipped 500,000 units in the first week. The handheld
device puts Apple on a direct collision course with the Kindle from Amazon, which Mr. Jobs ever
considered as pioneering the category.
     It is common knowledge that media companies hope the iPad will finally lead to available way
for them to charge for news, books and other materials. The half-inch thick, 1.5-pound device
features a 9.7-inch multi-touch screen and is powered by a customized(订制的)Apple microchip,
which is called A4. It has been designed with an exposed screen and without a camera or separate
keyboard. The iPad has the same operating system as the iPhone and also has access to its 140,000
applications.
     The price of the device starts at $499 for the most basic model, with a Wi-Fi wireless connection.
More expensive models with more memory and with 3G wireless access will cost $629 to $829,
depending on storage size.
     Because Apple is attempting to popularize a new kind of computing device, acceptance among
consumers is expected to be slower than with previous Apple devices. Critics assume that some
buyers are waiting for future versions of the iPad to appear, perhaps with a camera or USB ports
(端口).
     On its first day on sale, iPad users downloaded more than one million applications from the
company's AppStore and more than 250,000 electronic books from its iBookstore. A new wave
of apps is expected in response to the iPad. For an application developer, having an application
accepted for a highly desired Apple product means reaching a passionate group of consumers.
The potential income is huge: the apps market for the iPhone and iPod Touch alone is already
worth a billion dollars a year in sales.

1. In Mr Job's opinion, the iPad .

A. is a standard computer
B. is better than a laptop in any function
C. helps Apple to beat Amazon
D. is a "revolutionary" product between a laptop and a smart phone

2. Which of the following is NOT true of the iPad?

A. It is expected to benefit media companies.
B. It has a lot of similar features to a laptop.
C. It has a virtual keyboard.
D. It has the fastest Apple microchip.

3. The different prices of the iPad are determined by .

A. the size of the screen
B. the size of the memory
C. the speed of the microchip
D. the Wi-Fi wireless connection

4. What do we know from the fourth paragraph?

A. Some consumers hope for an iPad with more functions.
B. Buyers can improve their iPads with USB devices.
C. The iPad is basically different from conventional computers.
D. The iPad is accepted faster than former Apple products.

5. It is implied in the passage that .

A. people may download any application from the App Store
B. people would prefer to buy an iPad rather than an iPhone
C. owning an Apple product means that you will be respected
D. the Apple company will make more profit from the iPad
