It is difficult to imagine what life will be like without memory. The meanings of thousands of everyday perceptions(感觉、知觉), the bases for the decisions we make, and the roots of our habits and skills are to be found in our past experiences, which are brought into the present by memory.

  Memory can be defined as the capacity to keep information available for later use. It includes not only “remembering” things like arithmetic or historical facts, but also involves any change in the way an animal typically behaves. Memory is involved when a rat gives up eating grain because he has sniffed something suspicious in the grain pile. Memory is also involved when a six-year-old child learns to swing a baseball bat.

  Memory exists not only in humans and animals but also in some physical objects and machines. Computers, for example, contain devices from storing data for later use. It is interesting to compare the memory-storage capacity of a computer with that of a human being. The instant-access memory of a large computer may hold up to 100,000 “words”―ready for instant use. An average U. S. teenager probably recognizes the meaning of about 100,000 words of English. However, this is but a fraction(部分、片断) of the total amount of information which the teenager has stored. Consider, for example, the number of faces and places that the teenager can recognize on sight.

The use of words is the advanced problem-solving intelligence of human beings. A large part of a person’s memory is in terms of words and combinations of words.

66. According to the passage, memory is considered to be ________.

A. the basis for decision making and problem solving

B. an ability to store experiences of future use

C. an intelligence typically possessed by human beings

D. the data mainly consisting of words and combinations of words

67. The comparison made between the memory capacity of a large computer and that of a human being shows that ________.

A. the computer’s memory has a little bigger capacity than a teenager’s

B. the computer’s memory capacity is much smaller than an adult human being’s

C. the computer’s memory’s capacity is much smaller even than a teenager’s

D. both A and B

68. The whole passage implies that _______.

A. only human beings have problem-solving intelligence

B. a person’s memory is different from a computer’s in every aspect

C. animals are able to solve only very simple problems

D. animals solve problems by instincts rather than intelligence

69. The phrase “in terms of” in the last sentence can best be replaced by ________

A. in connection with                         B. expressed by

C. consisting                                     D. by means of

70. The topic of the passage is __________.

A. What would life be like without memory?

B. Memory is of vital importance to life.

C. How is a person’s memory different from an animal’s or a computer’s?

D. What is contained in memory?

Lawmakers in the United States have expanded an investigation into the use of location-tracking systems on mobile devices. The action follows recent reports about the storing of information on the Apple iPhone. Some people consider location tracking to be a threat to personal privacy and security.
Allan Friedman, the research director, says, “All wireless companies do some location tracking as part of their networks. This information is usually stored by the companies, not the devices, and there are laws to protect it. Law enforcement(执法) agencies, for example, have to have a fairly high standard before it can access that data. And the phone company is also prohibited from selling that information.
Now, two researchers report that location tracking information is being stored directly on Apple devices. They said Apple’s newest operating systems gather global positioning system and timestamp information. The information is stored on the device in a file that is also uploaded (上传) to any computer that the device is connected to. The researchers say the information is available to anyone who has access to the device or computer.
Allan Friedman says, “This raises additional concerns. There’s the idea that because it’s on my phone and on my computer, rogue applications(恶意程序) that I pay for or that I’m tricked into downloading may be able to access this data and somehow misuse it.”
Apple says it is “not tracking the location of your iPhone”. It is simply keeping a database of Wi-Fi hotspots and cell phone towers near the user’s location. This information is meant to help the iPhone quickly find its location when needed.
Letters have been sent to some of the leading mobile device developers, including Apple and Google. The letters asked for more information about their location tracking systems. Allan Friedman calls this an important start to strengthening privacy laws. He says, “There aren’t strong controls over things like location information, what they are doing with it, how long they are keeping it. And perhaps the most important question is, is my location data with other facts about me?”
