In a recent interview,neuroscientist Dr Lisa Chen explained why forgetting is not always a bad thing."Imagine if you remembered every single detail of your life-every face you passed on the street,every meal you ate last year,every phone number you ever used.Your brain would be so full of information that it would be hard to find what you really need," she said."Forgetting helps us clear out unnecessary information so we can focus on what matters.” Another reason we forget is to make room for new information.For example,when you learn a new school timetable or a new bus route,your brain needs to let go of the old one. Being able to forget old or unimportant details helps us adapt to new situations. There's also a common experience called the "tip-of-the-tongue"feeling.You know you 0 know a word or a name,but you just can't say it at that moment.Interestingly,people with a larger vocabulary often experience this more often,because their brains have more information to sort through to find the right word. So the next time you forget something, don't worry too much.Your brain is probably just doing its job-cleaning up to make space for something new. ()1.How does the writer introduce the topic?

()3.Who is more likely to experience the “tip-of-the-tongue'”feeling？ A.People with a smaller vocabulary. B.People who never forget anything. C.People with a larger vocabulary. D.People who don't read books. ()4.What is the main purpose of the passage? A.To explain why forgetting can be good. B.To teach people how to remember better. C.To describe how memory works.
