Read the following article and select the best answer. Article: Memory is the ability to keep track of things that have happened in the past. Memory really is learning. One needs memory to ride a bicycle. A dog needs to remember if it is to come when called. Memory is said to be stored in the brain as a "memory trace ." What makes up this trace is not known. Some scientists believe that certain chemical substances may carry certain memories. For example, one substance, when given to rats, causes them to fear the dark. Other research into memory has to do with how the brain works. Psychologists use three means to find out how a person remembers. For example, give a person a grocery list. Let the person memorize the list, then put it away. The most natural way to find out how much a person remembers of the grocery list is to ask what he or she remembers. This is called the method of recall. Another method is called recognition. Give the person another grocery list. Ask him or her to choose items on the first list from the items that are on only the second list. Often a person will be able to recognize things that he or she cannot recall. A third method of finding how much a person remembers is called relearning. Here the person is asked to read over the first list. The person will probably learn the list the second time faster than he did the first time. The difference in the time it takes to relearn the list is thought of as a measure of how much a person has remembered. One way of remembering something is to repeat it many times. Interest is very important. Boring lists of facts are much more difficult to remember than something that we understand and are interested in. Motivation, or wanting to do something, is also important. Motivation is linked with reward. For example, a hungry animal quickly learns how to do something if that action gets the animal food. In humans, wanting to learn is often motivation. The praise of a teacher or the knowledge that an answer is correct is rewarding. Question: The way to pick out the items on the first list from the second is known as _ . - recognition - recall - memorization - relearning
**Answer**
recognition

Read the following article and select the best answer. Article: Mom's birthday present? It may be a difficult thing for some people, but for me, it is an easy thing. Mom loved flowers, so every year I sent her flowers. Actually she had a bed of irises in the backyard of her small, Indiana farm. They were beautiful. "Take some," she said, "Dig some up and plant them on the side of your own house." But in my yard they became lacking in energy. A year passed, then two, but not one flower appeared. I cut back all their green leaves. I was tired of seeing them so lonely. Finally, I dug the irises up and threw them away. About that time Mom died unexpectedly. My sister and I sold the farm. I never went back to see the irises. I just couldn't bear seeing another family living in our home--Mom's home. Autumn came, then winter. The following spring, as Mom's birthday approached, I struggled with the question of how to remember her. I stared out the window and saw a few stubborn irises in my side yard sprouting , --tall, thin but flowerless. Because of seeing them, I decided to order flowers as I always did on Mom's birthday, and send them to my sister. I wished so badly I could still send flowers to Mom. But that was impossible. In the morning of Mom's birthday, I was in my car ready to work. Something in the yard caught my eye. The irises! One had bloomed with flowers, big, showy and purple, as lovely as they ever had been on Mom's farm. I smiled and turned my eyes upward. I could no longer send flowers to Mom. But somehow, she'd been able to send them to me. Question: At first, the irises in the author's yard _ . - all died quickly - didn't bloom at all - grew as well as on Mom's farm - grew better than those on Mom's farm
**Answer**
didn't bloom at all

Read the following article and select the best answer. Article: Here is an astonishing and signficant fact:Mental work alone can't make us tired. It sounds absurd. But a few years ago, scientists tried to find out how long the human could labor without reaching a stage of fatigue . To the amazement of these scientists, they discovered thett blood passing through the brain, when it is active, shows no fatigue at all! If we took a drop of blood from a day labourer, we could find it full of fatigue toxins and fatigue products. But if we took blood from the brain of Albert Einstein, it would show no fatigue toxing at the end of the day. So far as the brain is concerned, it can work as well and swiftly at the end of eight or even twelve hours f efforts as at the beginning. The brain is totally tireless. So what makes us tired. Some scientists declare that most of our fatigue come from our mental and emotional attitudes. One of England's most outstanding scientists. J. A. Hadfield,says,"The greater part of the fatigue from which we suffer is of mental origin. In fact,fatigue of purely physical origin is rare." Dr. Brill, a famous American scientist, goes even further. He declares,"One hundred percent of the fatigue of a sitting worker in good health is due to emotional problems." What kinds of emotions make sitting workers tired?Joy?Satifaction?No!A feeling of being bored,anger,anxiety,tenseness,worry,a feeling of nt being appreciated---those are emotions that tire sitting workers.Hard work by itself seldom causes fatigue.We get tired because our emotions produce nervousness in the body. Question: What surprised the scientists a few years ago? - Fatigue toxinscould hardly be found in a labour's blood. - Albert Eistein didn't feel worn out after a day's work. - The brain could wrk for many hours without fatigue. - A mental worker's blood was filled with fatigue toxins.
**Answer**
The brain could wrk for many hours without fatigue.
