A
Many people complain that they have poor memory and always forget things easily. However, most ordinary people have similar memory ability. The difference lies in whether they master correct memory methods.
First of all, forgetfulness is normal. Our brain will automatically forget useless information to make room for new knowledge. This is a self-protection mechanism of the brain. So we don’t need to worry too much about occasional forgetfulness.
Secondly, timed review is the key to long-term memory. Newly learned knowledge fades very fast. If we review it within 24 hours, most information can be kept. Regular review can turn short-term memory into long-term memory.
Thirdly, focused learning matters a lot. Many students forget knowledge quickly because they study with distractions. Looking at books while listening to music or chatting will reduce brain efficiency. Full concentration can greatly improve memory effect.
In short, good memory is not born. It comes from scientific methods and long-term persistence.
31. Why do people forget things occasionally
A. Because they are too stupid
B. Because the brain needs space for new knowledge
C. Because they never study hard
D. Because they have bad sleeping habits
32. What is the key to long-term memory
A. Doing sports every day
B. Timed review
C. Listening to music
D. Staying up late
33. Which of the following can improve memory
A. Studying with full concentration
B. Learning with many distractions
C. Never reviewing knowledge
D. Forgetting things casually
B
Human memory can be divided into short-term memory and long-term memory. Short-term memory only lasts for a few seconds or minutes. It can only store a small amount of information. For example, we can remember a new phone number for a short time, but we will soon forget it without repetition.
Long-term memory can last for months, years or even a lifetime. Important events, familiar names and daily skills are all stored in long-term memory. The biggest difference between the two is duration and storage capacity.
Researchers have found that the transformation from short-term memory to long-term memory needs two necessary conditions: repetition and understanding. Simple mechanical repetition is useful, but understanding knowledge can make memory more solid and lasting.
Besides, emotional feelings also affect memory deeply. Things with strong emotional impact, whether happy or sad, are easier to keep in long-term memory. That’s why we can still remember our childhood stories clearly after many years.
34. Which is true about short-term memory
A. It lasts for many years
B. It stores plenty of information
C. It fades away quickly
D. It needs no repetition
35. What can help turn short-term memory into long-term memory
A. Reading quickly
B. Repetition and understanding
C. Having a rest
D. Talking with others
36. Why do we remember childhood stories clearly
A. Because they are very easy
B. Because they have strong emotional feelings
C. Because we review them every day
D. Because they are very simple skills
C
Memory training is a popular and practical learning skill. Here are three easy memory training tips for middle school students.
Tip 1: Picture imagination
Our brain remembers pictures better than words. When learning new words or sentences, we can imagine vivid pictures in our mind. The more vivid the picture is, the deeper the memory will be.
Tip 2: Classification memory
Messy information is hard to remember. We can classify knowledge according to different types. For example, when learning English words, we can divide them into food, animals, clothes and other categories. Classification makes memory more orderly.
Tip 3: Fragmented time learning
We don’t need to spend long hours memorizing at one time. Using fragmented time such as after class, before meals or before bedtime to review knowledge can achieve better results. Short and frequent training is more effective for memory.
These methods are simple but practical. If you stick to them, your memory ability will be improved greatly.
37. What does the passage mainly talk about
A. The importance of memory B. Three ways to train memory
C. Different kinds of memory D. The history of memory study
38. Why does picture imagination help memory
A. Because brain prefers pictures to words
B. Because pictures are very colorful
C. Because pictures are easy to draw
D. Because pictures cost little time
39. Which is the advantage of classification memory
A. It saves learning time completely
B. It makes knowledge orderly
C. It makes learning full of fun
D. It needs no brain work
40. Which of the following is TRUE
A. Long-hour memorizing is always the best way
B. Fragmented time training is helpful for memory
C. Messy information is easy to remember
D. We only need one method to remember everything
