Questions 6 to 10 are based on the followingpassage:
It is difficult to imagine what life would belike without memory. (78) The meanings of thou-sands of everydayperceptions, the bases for the decisions we make, and the roots of our habitsand skills are to be found in our past experiences,which are brought into thepresent by memory.
Memory can be defined as the capacity to keepinformation available for later use. It includes not only “remembering” thingslike arithmetic or historical facts, but also involving any change in the wayan animal typically behaves. (79) Memory is involved when a rat gives upeating grain be-cause he has sniffed something suspicious in the grain pile. Memoryis also involved when a six- year-old child learns to swing a baseball bat.
Memory exists not only in humans and animalsbut also in some physical objects and ma-chines. Computers, for example,contain devices for storing data for later use. It is interesting to comparethe memory-storage capacity of a computer with that of a human being. Theinstant-access memory of a large computer may hold up to 100,000 “words”一ready for instant use. An averageU. S.teenagerprobably recognizes the meaning of about 100,000 words of English. However,this is but a fraction of the total amount of information which the teenagerhas stored. Consider, for ex-ample ,the number of faces and places that the teenager can recognize on sight.
The use of words is the basis of the advancedproblem-solving intelligence of human beings. A large part of a person’s memoryis in terms of words and combinations of words.

When a consumer finds that an item she or he bought is faulty or in some way does not live up to the manufacturer's claim for it, the first step is to present the warranty, or any other records which might help at the store of purchase. In most cases, this action will produce results. However, if it does not there are various means the consumer may use to gain satisfaction.
A simple and common method used by many consumers is to complain directly to the store manager. In general, the "higher up" the consumer takes his or her complaint, the faster he or she can expect it to be settled in such a case, it is usually settled in the consumer's favor, assuming, he or she has a just claim.
Consumers should complain in person whenever possible, but if they cannot get to the place of purchase, it is acceptable to phone or write the complaint in a letter.
Complaining is usually most effective when it is done politely but firmly and especially when the consumer can show what is wrong with the item he has bought. If this cannot be done, the consumer will succeed best by presenting specific information as to what is wrong, rather than by making general statements. For example "The left speaker does not work at all and the sound coming out of the right one is unclear" is better than "This stereo does not work".
The store manager may advise the consumer to write to the manufacturer if so, the consumer should do this, stating the complaint as politely and as firmly as possible. But if a polite complaint does not achieve the desired result, the consumer can go a step further. She or he can threaten to take the seller to court or report the seller to a private or pubic organization responsible for protecting consumers' rights.
When a consumer finds that his purchase has a fault in it, the first thing he should do is to ().
A.complain personally to the manager
B.threaten to take the matter to court
C.write a firm letter of complaint to the store of purchase
D.show their written proof of the purchase to the store

"If your computer is down, just write me out a ticket."
"I can't write you out a ticket. The computer is the only one allowed to do so."
I looked down on the computer and every passenger was just standing there staring at the black screen. Then I asked her, "What do all you people do?'
"We give the computer the information about your trip, and then it tells us whether you can fly with us or not."
"So when it goes down, you go down with it."
"That's good, sir. '
"How long will the computer be down?" I wanted to know.
"I have no idea. There's no way we can find out without asking the computer."
After the girl told me they had no backup (备用) computer, I said. "Let's forget the computer. What about your planes? They're still flying, aren't they?"
"I wouldn't know," she said, pointing at the dark screen. "Only 'IT'knows. 'It'can't tell me.
By this time there were quite a few people standing in lines. The word soon spread to other travelers that the computer was down. Some people started to cry and still others kicked their luggage.

A.When the Computer Is Down
B.How to buy a ticket

D.Asking the Computer
The marvel of the machine age, the electronic computer has been in use only since 1946. It can do simple computations—add, subtract, multiply, and divide—with lightning speed and perfect accuracy. It can multiply two 10-digit numbers in 1/1, 000 second, a problem that would take an average person five minutes to do with pencil and paper. Some computers can work 500, 000 times faster than any person can.
Once it is given a program, that is, a carefully worked-out set of instructions devised by a technician trained in computer language, a computer can gather a wide range of information for many purposes. For the scientist it can get information from outer space or from the depths of the ocean. In business and industry the computer prepares factory inventories, keeps track of sales trends and production needs, mails dividend checks, and makes out company payrolls. It can keep bank accounts up to date and make out electric bills. If you are planning a trip by plane, the computer will find out what route to take and what space is available.
Why does the author regard the electronic computer as the marvel of the machine age?
A.Because electronic computers are rare.
B.Because people know little about electronic computers.
C.Because electronic computers can do much more kinds of work that human beings can't.
D.Because electronic computers have been widely suspected.
One can make a password safer by ______.
A.inserting pictures between numbers
B.avoiding the use of letters altogether
C.setting up a firewall against computer hackers
D.using complicated combinations of numbers and letters
A.work rapidly
B.be large and expensive
C.be easy to use
D.be used for fun
