（一）

Research shows that many animals have good long-term memories.     1     For example, when squirrels hide food, they go straight to the place where they hid nuts.     2     Humans do not know for sure why wild geese seldom get lost. A similar situation happens to dolphins.     3     —even when they have not met each other for a long time.

So how can you improve your memory? Here are some tips. First, pay attention.     4     After all, it is easier to remember a summary than every word in a speech. Second, use it or lose it. The more you review what you learn, the more likely you will remember it. You can also review information by discussing it with others or by teaching

others.     5     Create images by using tables, graphs, and mind maps to process information.

A．They know where food can be found and where it is safe.

B．Every autumn, wild geese fly thousands of kilometres south for the winter.

C．So, try taking notes by writing down key points.

D．They can remember the way to the park.

E．But you should not wear out your brain.

F．Third, make use of your senses.

G．They can recognize voices of other dolphins.

How can we have a good memory? Here are some tips for you.

First, link new knowledge with what you already know.     6     For example, when you learn a new word, try to connect it with a picture or a story you know well.

Second, retell what you have learned in your own words.     7     It helps you understand the material better and remember it longer.

Third, pay attention to details.     8     Details are the key to understanding the whole picture.

Fourth, take notes actively in class.     9     Reviewing them carefully after class is also important.

Finally, don’t be afraid of forgetting.     10     Therefore, keep in mind what you still remember and try to make new happy memories.

A．Knowledge is like a chain — more links help you remember better.

B．Writing things down helps you remember them.

C．Good notes can help you understand and remember key points.

D．Instead of focusing on what you forget, focus on what you remember.

E．This means you should notice small things, not just the big picture.

F．You should always ask your teacher for help.

G．Telling a story in your own words is a powerful way to remember.

Many of us learn how to ride a bike at a young age.     11     But whenever we get on a bike, it’s like we’ve never stopped biking.

This is strange. In many other cases, we often find it hard to remember the name of a person or a place, don’t we?     12   

The answer is that certain skills, such as how to drive or play an instrument, are part of our procedural (程序性

的) memory. It is a kind of long-term memory that performs different procedures.     13     But once you learn them completely，you never forget them.

This happens because procedural memory and declarative (陈述性的) memory are stored in different parts of the brain.     14     It will help you remember some things like names, dates, and events from your life. Studies say that the cells (细胞) in the part storing procedural memory can not easily be lost or get hurt. So procedural memories can’t be forgotten very often.

    15     Can you name other skills that you’re also unlikely to ever forget?

A．These procedures may be difficult to learn.

B．Here are some useful tips on riding a bike.

C．As we grow older, we may stop riding bikes.

D．So how can we improve our skills by practising?

E．Now you know why we don’t forget how to ride a bike.

F．Declarative memory mainly deals with the task of remembering information.

G．So why can we still ride a bike after we stopped riding a long time ago?

The Power of Memories

Memories are an important part of our lives.     16     They help us remember the happy times and learn from the sad times.

Some memories are happy.     17     For example, the day you won a prize or the day you made a best friend. These memories make us feel warm and happy when we think of them.

Other memories are sad.     18     For example, the day you failed an exam or the day you said goodbye to a friend. These memories may make us feel sad, but they also teach us important lessons.

    19     When we face difficulties, we can think of happy memories and feel better. When we make mistakes, we can think of sad memories and learn from them.

So we should cherish our memories.     20     We should also try to create new happy memories with our family and friends every day.

A．They are like treasures in our hearts.

B．They make us feel happy and warm.

C．They make us feel sad and upset.

D．We should not forget them.

E．Memories can also give us strength.
