Read the following article and answer the question. Article: We take it for granted that with memory we can remember most of things which happened in our life. But it is difficult to imagine what life would be like without memory. The meanings of thousands of everyday perceptions , the basis 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 ability to keep information available for later use. It not only includes "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 exists not only in humans and animals but also in some physical objects and machines. Computers, for example, contain devices for 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"--strings of alphabetic or numerical characters--ready for instant use. An average U.S. teenager probably recognizes the meaning of about 1000,000 words of English. However, this is but a part of the total amount of information that 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 basis of 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. But while language greatly expands the number and the kind of things a person can remember, it also requires a huge memory capacity. It may well be this capacity that distinguishes humans, setting them apart from other animals. Question: According to the passage, memory is helpful in one's life in the following aspects EXCEPT that _ . Answer:
OPTIONS:
- it involves a change in one's behavior
- it keeps information for later use
- it warns people not to do things repeatedly
- it enables one to remember events that happened in the past

Answer: it warns people not to do things repeatedly

Read the following article and answer the question. Article: At railway stations all across Britain next week, groups of students will gather with their backpacks to wait for the trains that will carry them home for Christmas. This is as large a movement of human beings as before, but with more contradictory traffic flows, so that trains filled with the young pass each other travelling in every direction. At first, I went home every weekend with my washing, but then those visits became less regular. How did I let my parents know I was coming? They had no phone. Perhaps I wrote to them ("Expect me with dirty shirts this Friday afternoon"), but more likely I didn't let them know, and just turned up or didn't turn up, not understanding that my parents' dashed hopes of seeing me were a greater casualty of my carelessness than a spoiled tea. And in all this I suspect I was typical, at least of young men. As for our fathers and mothers, none of them talked of "empty-nest syndrome", even though its implication that the principal human duty is to protect and feed the young would have suited their generation better than ours. Then, the feelings of loss went without a name. Today, it's a condition with _ , which will make parents feel more enjoyable in their life. The Mayo Clinic, for example, suggests you try to maintain regular contact with your children through "visits, phone calls, emails, texts or video chats". If you feel depressed, lean on loved ones or your mental health provider. Above all, stay positive: "Thinking about the extra time and energy you might have to devote to your marriage or personal interests after your last child leaves home might help you adapt to this major life change." What can't be denied, however, is that children often leave home. In modern societies, this is what they do. Christmas is the very time they can be depended on to return. For the non-religious, that may be this season's true comfort and significance. Question: From the passage we can infer that by writing the article the writer's purpose is to _ . Answer:
OPTIONS:
- persuade the young to show concern for their parents
- ask the young to go home regularly
- make the young understand their parents' interests
- enable the young to be more independent

Answer: persuade the young to show concern for their parents

Read the following article and answer the question. Article: Most of us fear getting up and speaking in public. Many people don't like to go gathering where they don't know anyone, but while most of us soldier on , those with social anxiety disorder are often stopped by the terror and worry. Research shows that around fifteen million Americans suffer from social anxiety disorder. People in this condition feel that they are always being watched. Even though they know these fears are unreasonable, they cannot overcome their fears on their own. Social anxiety disorder sufferers are often misdiagnosed with conditions such as schizophrenia and personality disorder. Many feel lonely, and are unsure whether anyone else can understand their thoughts and emotions. This can lead to withdrawal from most social situations, even to being unable to hold employment. Those who suffer from social anxiety disorder are often dismissed as being shy. This is simply not the case; shyness is not even a symptom of social anxiety disorder. The majority of sufferers find their symptoms linked to specific situations, rather than all types of social interactions. An important step in overcoming social anxiety disorder is seeking out a therapist who specializes in training this type of disorder. Group treatment has been shown to be especially effective. Medication also help reduce the symptoms, but it should not be used as a replacement for psychotherapy . On your own, you can help reduce the symptoms by taking deep breaths and practising medication or prayer. Alcohol and nicotine should be avoided, as both can cause panic attacks. Exercises can relieve the symptoms, because it burns up the chemicals in your body that cause stress. Question: According to the passage, if Jack suffers from social anxiety disorder, he should _ . Answer:
OPTIONS:
- burn up some unsafe chemicals
