Grown-ups are often surprised by how well they remember something they learned as children but have never practiced ever since. A man who has not had a chance to go swimming for years can still swim as well as ever when he gets back in the water. He can get on a bicycle after many years and still ride away. He can play, catch and hit a ball as well as his son. A mother who has not thought about the words for years can teach her daughter the poem that begins “Twinkle, twinkle, little star” or remember the story of Cinderella or Goldilocks and the Three Bears.

One explanation is the law of overlearning, which can be stated as follows: Once we have learned something, extra learning trials (尝试) increase the length of time we will remember it.

In childhood we usually continue to practice such skills as swimming, bicycle riding, and playing baseball long after we have learned them. We continue to listen to and remind ourselves of words such as “Twinkle, twinkle, little star” and childhood tales such as Cinderella and Goldilocks. We not only learn but overlearn.

The multiplication tables (乘法口诀表) are an exception (例外) to the general rule that we forget rather quickly the things that we learn in school, because they are another of the things we overlearn in childhood.

The law of overlearning explains why cramming (突击学习) for an examination, though it may result in a passing grade, is not a satisfactory way to learn a college course. By cramming, a student may learn the subject well enough to get by on the examination, but he is likely soon to forget almost everything he learned. A little overlearning, on the other hand, is really necessary for one’s future development.

1. What is the main idea of Paragraph 1?
A.People remember well what they learned in childhood.
B.Children have a better memory than grown-ups.
C.Poem reading is a good way to learn words.
D.Stories for children are easy to remember.
2. The author explains the law of overlearning by ________.
A.presenting research findings
B.setting down general rules
C.making a comparison
D.using examples
3. What does the word “they” in Paragraph 4 refer to?
A.Commonly accepted rules.
B.The multiplication tables.
C.Things easily forgotten.
D.School subjects.
4. What is the author’s opinion on cramming?
A.It’s helpful only in a limited way.
B.It leads to failure in college exams.
C.It’s possible to result in poor memory.
D.It increases students’ learning interest.

文章大意:本文是一篇说明文。文章主要讲述了手写相比打字对于大脑活动的好处,手写会激活大脑更多的区域,比如记忆区域和学习区域,孩子们应该更多地接触手写。

【推荐1】As digital devices have taken over society, “keyboard activity is now often recommended as a replacement for early handwriting,” a new study notes. The idea is that typing may be easier for young children.

The potential benefits of handwriting for learning and memory have been debated for some time. The new study set out to answer two questions. How does handwriting compare to using a keyboard or drawing when it comes to learning new information? And how similar are handwriting and drawing?

In all, 12 adults and 12 seventh-graders took part. Researchers asked each of them to write and draw with a digital pen. Each was also asked to type on a keyboard. While performing these tasks, each volunteer wore a cap that held electrodes (电极) next to their head. It looked somewhat like a hair net fitted with 256 sensors, which recorded the volunteers’ brainwaves, a type of electrical activity, as EEGs.

The electrodes noted which parts of the brain turned on during each task. And they showed that the brain activity was about the same in both the kids and the adults. Writing turned on memory areas in the brain. Typing didn’t. Drawing images and writing also turned on parts of the brain involved with learning. Writing even activated language areas.

This suggests, according to Van der Meer, the new study’s leader, that when we write by hand, “we both learn better and remember better.” Her team now suggests “that children, from an early age, must be exposed to handwriting and drawing activities in school.”

These new findings back up other studies showing potential benefits of handwriting, says Joshua Weiner, who was not involved with the new study. His own students type faster than they can write, he finds. Slowing down seems to require them to “think more” when taking notes, he says. He adds that this could “improve memory and enhance learning.” Weiner concludes that “writing may be beneficial” as it involves more of a “brain response”.

Van der Meer recognizes that learning to write by hand is a slower process. She is also aware that it requires fine motor skills. But, she adds, “If we don’t challenge our brain, it can’t reach its full potential.”

1. A cap was used in the experiment to ________.
A.give the volunteers instructions
B.record the volunteers’ every move
C.help the volunteers better focus on the task
D.keep track of the volunteers’ brain activity
2. What does Paragraph 3 mainly talk about?
A.The tools invented by the researchers.B.The background of the participants.
C.The process of the experiment.D.The application of the study.
3. What did the research team find?
A.Typing made the brain more active.
B.Writing turned on more areas in the brain.
C.Drawing activated the area related to memory.
D.Adults could do better than kids in taking notes.
4. Which of the following would Van der Meer probably agree with?
A.Keyboards should be used as little as possible.
B.Requirements for hand-written notes will benefit kids.
C.The process of writing slows down the brain response.
D.Typing gives us a chance to improve memory and learning.

文章大意:这是一篇说明文。一项研究发现,女性可能认为男性戴口罩更有吸引力。

【推荐2】A study, which was published in the magazine Cognitive Research: Principles and Implications, found that women may consider men wearing face masks as more attractive. The researchers find that not only do coverings change people's attractiveness but the type of covering plays a role as well.

Dr. Michael Lewis, a professor at Cardiff University’s School of Psychology, said,“Research carried out before the pandemic found that medical face masks reduce attractiveness — so we wanted to test whether this had changed since face coverings became omnipresent during the spread of COVID-19 and understand whether the type of mask had any effect.”

“Our study suggests that faces are considered most attractive when covered with medical face masks. This may be because we're used to healthcare workers wearing blue masks and now we associate these with people in caring or medical professions,”Lewis explained.“At a time when we feel insecure, we may find the wearing of medical masks reassuring(使人安心的) and so feel more positive towards the wearer.”

The study also suggested that people's faces were thought of as dramatically more attractive when covered with masks compared with being uncovered.“ Some of this effect may be a result of being able to hide undesirable features in the lower part of the face --- but this effect was present for both less attractive and more attractive people,” Lewis said. The team conducted the study by asking 43 women to rank the attractiveness of images of men's faces without a mask, wearing a cloth mask, wearing a blue medical mask, and holding a black book covering the area a face mask would hide.

The participants said those wearing a cloth mask were more attractive than the ones with no masks or whose faces were partly covered by the book. But the surgical mask--- which was just a normal kind----made the wearer look even better.

“The results are opposite of the pre-pandemic research where it was thought masks made people think about disease and the persons should be avoid," said Lewis. “ The pandemic has changed our mind in how we treat the wearers of masks. When we see someone wearing a mask we no longer think‘that person has a disease,I need to stay away'.

1. Which of the following can replace the underlined word“omnipresent” in Paragraph 2?
A.Illegal.B.Strange.C.Common.D.Outdated.
2. Why do blue masks make men most attractive according to Lewis?
A.Blue masks make men look powerful.
B.Blue masks are related to medical professions.
C.Blue masks help women focus on men's faces directly.
D.Blue masks can hide undesirable features on men's faces.
3. Which of the following image is probably ranked the least attractive according to the new study?
A.The one with a cloth mask.B.The one with a blue mask.
C.The one with no masks.D.The one totally covered by the book.
4. Which can be the best title for the text?
A.Face masks make people more attractive
B.Less attractive men are more affected by masks
C.Face masks may reduce women's attractiveness
D.Masks change the features of our faces effectively

【推荐3】Expensive perfumes (香水) come in tiny bottles, but many hide a whale-sized secret.
To perfect a particular smell, perfume-makers often use an ingredient that comes from sperm whales, called ambergris (龙涎香). But using ambergris, which helps a perfume last longer, is strongly opposed by many people who think it is wrong to kill whales just so we can smell sweet. Joerg Bohlmann is neither a perfumer nor a whale expert. He's a plant biologist at the University of British Columbia in Canada. But his discovery of a new plant gene (基因) might push whales out of the perfume business.
The gene comes from fir trees, found throughout North America and commonly used as Christmas trees. The trees produce a chemical that can be used in perfume in place of ambergris-but with a catch "There's a problem that many people wouldn't consider. In the tree, the chemical is mixed with many others. That makes separation a challenge," Bohlmann says. "lt's like trying to isolate sugar from a biscuit. "
This is where science becomes useful. When Bohlmann learned that fir trees produce the ambergris-like chemical, he decided to use his gene know-how to find the instructions for how to make the ambergris-substitute.
Bohlmann found that gene and took it out of the tree cells. Then he did something that might sound strange to someone who doesn't work in genetics: Bohlmann put the gene from the tree into yeast (酵母) cells.
Yeast may sound familiar because it's used to make things like bread, wine and beer. Biologists like to work with yeast because it easily adopts new genes and changes its features and behaviour. When Bohlmann put the fir tree gene into the yeast, the yeast started making the same chemical that had been produced by the tree.
Perfumers pay big money for ambergris because it is a fixative, which means it holds a smell in place on a person's body.
"Cheap perfumes smell good in the first hour or so and then everything is gone," explains Bohlmann. "But expensive perfumes are much more stable. Their smell lasts much longer, for hours or even a day after you apply them. "
The new chemical, made from the tree genes, can be used as a fixative, too. And using yeast to make it is far cheaper than acquiring ambergris.
Bohlmann admits he never thought he'd get into the perfume business. But now, he says, producers have been calling to find out how to use his technology in new perfumes.
1. It can be inferred from the passage that if a perfume contains ambergris,          .
A.its user probably supports whale hunting
B.it is probably very expensive
C.its smell will last for about an hour
D.there will be a whale symbol on the bottle
2. The underlined expression "with a catch" in Paragraph 3 means____.
A.being difficult to hold
B.being too similar
C.having a hidden problem
D.needing further testing
3. According to the passage, why are yeast cells often used in genetic research?
A.They're much cheaper to use than ambergris.
B.They can reproduce much faster than other cells.
C.They share some of the qualities of plant genes.
D.They can take on the characteristics of other genes.
4. What can we learn about Joerg Bohlmann from the passage?
A.He is opposed to whale hunting.
B.He made his discovery during Christmas.
C.He has worked in the perfume industry for many years.
D.He has previously done genetic research.
