四、语法填空。
Do you have a good memory? Memory plays 15. important role in our daily life. Have you ever wondered 16. our memory works?
Professor Green once said, “Knowledge 17. (be) like a chain. New knowledge is best remembered by linking it with old knowledge. This helps us put what we learn 18. long-term memory.” Some people often forget things. They may mix up similar words or fail 19. (attend) important events. To avoid such problems, we should pay attention to 20. (detail) and create clear images in our minds when learning. Taking notes is also 21. (help). Family memories are 22. (especial) precious. Rick’s grandma sometimes forgets his name, 23. she still remembers Rick loves cookies. Maybe it will be better for us to keep in mind what 24. (we) loved ones remember instead of what they forget.
Try to improve your memory step by step and cherish beautiful moments in life.
