广东省深圳市桂圆中学2024-2025学年九年级上学期12月阶段学情反馈英语试题
We all have experienced the strong link between smell and memory. A whiff of chlorine(一股氯气) probably reminds you of summer pool parties, while the scent of flowers may bring back memories of your grandma's garden. Now, researchers from the University of California, Irvine (UCI) have found that breathing in pleasant smell could even help improve memory and learning.
The study, led by Cynthia Woo, invited 43 healthy adults aged between 60 and 85. The scientists divided them into two groups. The test group(实验组) was provided with some natural oils with different fragrances(芳香). They included orange, eucalyptus(桉树), lemon, peppermint(薄荷), rosemary(迷迭香), and lavender(熏衣草). However, the control group(对照组) only received fewer types of natural oils with different fragrances.
The participants were asked to use one of the scented oils(香精油) to perfume(使...充满香味) their homes for two hours every night for six months. They were also asked to change the fragrances every night.
At the end of the six months, all volunteers took a memory test. The test group outperformed the control group by a shocking 226 percent!
Woo and her team thought that it does not matter when the scents are taken in. However, varying the fragrances is the key. The scientists believe the changes of different smells helps activate (激活) the memory centers of human brains.
A new study has found that certain fragrances may help prevent memory loss in adults. The findings were published in the journal Frontiers in Neuroscience on July 24,2023. The study also showed that certain fragances could probably also help improve memory in younger people.
The UCI team's next plans are to carry out a similar study on older people who already suffering from memory loss. They are eager to learn if pleasant smells can help reverse(逆转) the memory loss.
If I could catch a rainbow (彩虹) I would do it just for you and share with you its beauty. On the days you're feeling blue. If I could build a mountain You could call your very own A place to find serenity(宁静) A place to be alone. If I could take your troubles I would toss(扔) them in the sea But all these things I'm finding are impossible for me. I cannot build a mountain Or catch a rainbow fair But let me be what I know best A friend that's always there. |
What Is a Good Friend Like? | |
Cindy | I think a good friend should be honest(诚实的). That's more important than any other thing. And it is where a real friendship starts. If a friend isn't honest, he may lose his friends' trust. |
Jenny | I think a good friend has to be generous(慷慨的). Being generous doesn't mean he has to give his friends his lunch money or his clothes. It means he should share his ideas and feelings with his friends. In fact, his friends can know him better in this way. |
Mary | In my eyes, a good friend should understand his friends. When there's something wrong between him and his friends, he can put himself in his friends' place and think more for his friends. |
