Can music make us smarter?

① An article published in Nature in 1993 inadvertently introduced the Mozart effect to the public. Psychologist Francis Rocher experimented with 36 college students and asked them to listen to Mozart's D minor sonata for 1 minutes before doing some spatial reasoning problems. Everyone else keep quiet. As a result, in the test of what shape a piece of paper will be when it is folded several times and cut open, people who listen to Mozart's music have made obvious progress. This discovery is vividly called Mozart effect. Since the Mozart effect was put forward, there has been a constant debate.

② Recently, scientists in China found that the rhythm of music may be the key to Mozart effect. Listening to Mozart is good for the brain, and you can observe the increase of newborn neurons; Listening to reverse Mozart has negative effects on both humans and rats, which will reduce the number of newborn neurons and the cognitive ability of behavior.

③ Music can make people smarter? To a certain extent, yes! Whether playing musical instruments or listening to music, the impact on the brain is far more than we think.

④ why can playing musical instruments make people smart? If the brain is compared to a factory, listening to music and playing musical instruments is a big project for this factory, and many important workshops will be mobilized. Scientists have scanned musicians with nuclear magnetic resonance technology and found that all important brain regions have a strong reaction to music. For example, playing the piano and other musical instruments with both hands stimulates and exercises the corpus callosum of the brain, which connects the left and right hemispheres of the brain, which is very important. If you are stimulated for a long time, your coordination ability will be greatly improved. The tactile response of people when playing musical instruments or dancing stimulates the motor cortex in the brain, which is specialized in controlling people's limb movements. In addition, other parts involved include hippocampus, amygdala, visual cortex and so on, which are responsible for memory function, emotional control, and visual perception and response. These important parts work together in the music to produce harmonious brain waves, which makes the brain function reach the optimal state.

⑤ In addition, in the performance of musical instruments, whether it is strings, wind music, plucked music or percussion music, the movement of the left hand always exceeds many times in daily life, and the use of the left hand can promote the development of the right hemisphere of the brain, which plays a very important role in improving the ability of storing and transmitting information and improving the thinking speed of the whole brain. The movement of hands cooperating with each other is very beneficial to improve the excitability of the whole cerebral cortex and improve the efficiency of work.

⑥ Of course, if you are afraid of learning to play musical instruments (a), listening to music often is also good for your brain (b). Scientists have proved through experiments that music, especially complex classical music, can also produce benign stimulation to various functions of the brain.

⑦ First of all, listening to music can enhance our spatial analysis ability. For example, activities such as solving particularly difficult problems, arranging complex things, figuring out the relationship between them, and solving puzzles all require our spatial information imagination and processing ability. Research shows that the mental activity of spatial analysis is the same as listening to classical music. Therefore, when we enjoy classical music, our big brain seems to be processing spatial information, and unconsciously, our brain has been exercised.

⑧ Secondly, listening to music can enhance our auditory processing ability. Musicians' hearing ability is obviously stronger than that of ordinary people, and their listening attention, that is, their ability to distinguish different sounds and remember what they have heard, is better than that of ordinary people. This is because music improves brain function. If ordinary people improve these abilities, it will be of great help to exams, remember important information and improve their language recall ability.

pet-name ruby music can make people smart. If you choose background music when you study or work, will the effect be better? Scientists have long discovered that music can have a subtle influence on people's emotions and behaviors. However, a new study by experts from London Institute of Education found that different kinds of background music have no difference in children's learning ability (C).

attending the experts divided the children into three groups: A, B and C.. Children in group A enjoy albinoni's soft and beautiful Adagio, children in group B listen to Kaelte Lin's jazz Trinity, while children in group C listen to nothing. Since then, all three groups of children have accepted reading comprehension, memorizing words, reciting texts and four arithmetic tests, and the test content is completely new knowledge. The final result shows that group A has the best average score, followed by group C, and group B has the worst average score.

　? Experts explain that over-active or aggressive background music can't play a positive role in children's brain cognitive mechanism like soft and beautiful background music, but on the contrary it will only play a negative role.

　? Obviously, in some cases, music can help you finish some boring tasks faster. If you want to learn complicated new knowledge, you need to (d) concentrate on it, and you'd better turn off the music. Because research shows that concerts weaken the cognition and learning ability of new knowledge.

1. Try to figure out the four words added in the text in combination with the context, among which the inappropriate one is () (2 points)

A. Fear and fear are of great benefit C. No difference D. Concentrate on the note

2. The rhythm of the music in the second paragraph can be ... it is the key for people to appear the special effects of Inga. Can the added words be removed? Please briefly explain the reasons. (only opinions, no reasons, no score) (4 points)

3. What explanation method is used in the underlined part of paragraph 4? What's the role? (4 points)

Answer

1. C

2. Cannot be removed. Because it may just mean speculation, it is not very sure, and if it is removed, it will become a positive meaning, which is inconsistent with scientific facts. This reflects the accuracy and rigor of the explanatory language.

3. give an example. Through this example, the reason why playing musical instruments can make people smart is explained: harmonious brain waves make brain function reach the optimal state, which is very convincing.

4. previewing a new lesson means learning new knowledge. overactive or aggressive background music will weaken your cognition and learning ability of new knowledge and play a negative role. (about 5 years) (4 points)

Graphene, the potential application is surprising. Read the attached answer

Graphene, the potential application is surprising

① In 217, scientists in Britain and China used different methods to accurately control the spacing between graphene oxide layers, so that smaller water molecules could pass through smoothly, while salt ions were blocked out. This achievement shows the great potential of graphene oxide in seawater desalination.

② Graphene oxide is the twin brother of graphene. The scientific term graphene has become a household name since British physicists stripped a single layer of graphene from a large piece of graphite in the laboratory in 24 by a seemingly incredible method of tearing tape. In just over ten years, the research on graphene has developed rapidly and shown extremely broad application prospects.

③ Graphene is a member of the carbon material family, which is a layered material formed by arranging carbon atoms in a hexagonal honeycomb structure in a plane. Because its thickness is only the size of one carbon atom, it is about .34 nanometer, which is equivalent to one 2 thousand of a hair. It is the thinnest material discovered by human beings so far, and graphene is also called a two-dimensional material.

④ it is precisely because of this special two-dimensional atomic structure that graphene shows many strange properties that ordinary three-dimensional materials do not have. The transmittance of single-layer graphene is as high as 97.7%, which is almost completely transparent to the naked eye. It has excellent thermal conductivity, and its thermal conductivity is more than twice that of diamond. Graphene has great mechanical strength, which is 2 times stronger than steel. If a single layer of graphene of 1 square meter is made into a hammock, a cat can be stably carried with a thickness of only .34 nm. Graphene also has excellent electrical properties, with stronger conductivity than silver and copper, and higher carrier mobility than carbon nanotubes and silicon.

⑤ Based on the excellent physical properties of graphene, people have high hopes for its application. The research in recent ten years shows that graphene has extraordinary application potential in basic research, high-frequency electronic devices, flexible displays, electrochemical biosensors, new energy batteries, supercapacitors, aerospace and other fields, and is known as the king of black gold and new materials.

⑥ Among many potential applications, graphene water purification technology is not only feasible in principle, but also has made many major breakthroughs in the laboratory. As we all know, activated carbon, as a common traditional sewage treatment material, has many loose pores inside and has strong adsorption capacity. The special layered and porous structure of graphene makes its adsorption capacity hundreds of times that of activated carbon. On this basis, through micro-regulation, modification and modification, scientists have made many different graphene-based adsorption materials with ultra-efficient adsorption characteristics, which can not only adsorb pollutants hundreds of times more than their own mass, but also be recycled, greatly reducing the use cost. It can be said that graphene provides a surprising new solution in sewage treatment and seawater desalination.

⑦ At present, the graphene industry in China has been listed in the 13th Five-Year National Strategic Emerging Industry Development Plan and one of the key development areas of Made in China in 225. The research level of graphene in China is very competitive internationally, and some technological breakthroughs, including graphene water purification technology, are gradually moving from laboratory to market application. We believe that new technologies and inventions related to graphene will enter people's daily lives in the near future and bring great gospel to mankind.
