1 . This is Your Dream Dance

With growing evidence that dancing helps boost brain health and manage symptoms of neurocognitive (神经认知的) and movement disorders, accessible dance programmes and movement therapists are helping improve the lives of millions.     1    .

● Dance as brain movement

There’s actually a lot more happening inside the brain when trying to follow even the simplest choreography (舞蹈编排). “In dance class, we have to learn patterns, and remember sequences,” says David Leventhal, a programme director. The effect extends beyond the dance class to the real world.     2    .

In addition to the physical and neurological benefits, dance can also help people living with disease make out what their bodies can and can’t do. Rather than trying to control, or “fix” our body, dance is about developing greater body awareness and moving at our capacity, regardless of physical or cognitive difference.

● Dance as community

    4    . Dancing with others not only makes people feel less different in their abilities when dealing with neurological and movement disorders, it also helps to combat the loneliness and social isolation of living with a chronic illness.

Still, researchers say they’re only scratching the surface of understanding how dance can be used therapeutically.     5    . Researchers are also trying to find out the most effective types of dance movements and the optimal length and frequency of classes.

A．Dance as body acceptance

B．Dance as physical exercise

C．The uniqueness of dance as a therapy lies in the following aspects

D．Dancing requires more “brain power” than simpler repetitive exercises

E．Perhaps one of the biggest benefits of dance is the sense of belonging it creates

F．Larger studies are needed to confirm the findings of the smaller trials that have been done

G．Tasks like navigating the kitchen or walking to the bus stop can be more attainable after dancing

3 . In the late 1930s, people could donate blood, but very few hospitals could store it for later use. Whole blood breaks down quickly, and there were no methods at the time for safely preserving it. As a result, hospitals often did not have the appropriate blood type when patients needed it. Charles Drew, a Black surgeon and researcher, helped solve this monumental problem for medicine, earning him the title “Father of the Blood Bank.”

In 1938, while obtaining his doctorate in medicine, Drew became a fellow at Columbia University’s Presbyterian Hospital in New York. He studied the storage and distribution of blood, including the separation of its components, and applied his findings to an experimental blood bank at the hospital.

As Drew was finishing his degree at Columbia, World War II was erupting in Europe. Great Britain was asking the United States for desperately needed plasma (血浆) to help victims. Given his expertise, Drew was selected to be the medical director for the Blood for Britain campaign. Using Presbyterian Hospital’s blood bank as a model, Drew established uniform procedures and standards for collecting blood and processing blood plasma from nine New York hospitals. The five-month campaign collected donations from 15,000 Americans and was considered a success. His discoveries and his leadership saved countless lives.

With the increasing likelihood that the nation would be drawn into war, the United States wanted to capitalize on what Drew had learned from the campaign. He was appointed as the assistant director of a three-month pilot program to mass-produce dried plasma in New York, which became the model for the first Red Cross blood bank. His innovations for this program included mobile blood donation stations, later called bloodmobiles.

4 . A quick increase of dopamine (多巴胺) shifts mice into a dreamy stage of sleep. In the mice’s brains, the chemical messenger triggers rapid-eye-movement sleep, or REM, researchers report in the March 4 Science.

These new results are some of the first to show a trigger for the shifts. Understanding these transitions in more detail could ultimately point to ways to treat sleep disorders in people.

Certain nerve cells in the ventral tegmental area of the mouse brain can pump out dopamine, a molecule that has been linked to pleasure, movement and learning, which is then delivered dopamine to the amygdalae, two almond-shaped structures deep in the brain that are closely tied to emotions.

Using a molecular sensor that can tell exactly when and where dopamine is released, the researchers saw that dopamine levels rose in the amygdalae just before mice shifted from non-REM sleep to REM sleep.

Next, the researchers forced the mice into the REM phase by controlling those dopamine-producing nerve cells using lasers and genetic techniques. Compelled with light, the nerve cells released dopamine in the amygdalae while mice were in non-REM sleep. The mice then shifted into REM sleep sooner than they typically did, after an average of about two minutes compared with about eight minutes for mice that weren’t prompted to release dopamine. Stimulating these cells every half hour increased the mice’s total amount of REM sleep.

Additional experiments suggest that these dopamine-making nerve cells may also be involved in aspects of narcolepsy (嗜睡症). A sudden loss of muscle tone, called cataplexy, shares features with REM sleep and can accompany narcolepsy. Stimulating these dopamine-making nerve cells while mice were awake caused the mice to stop moving and fall directly into REM sleep.

The results help clarify a trigger for REM in mice; whether a similar thing happens in people isn’t known. Earlier studies have found that nerve cells in people’s amygdalae are active during REM sleep.

Many questions remain. Drugs that change dopamine levels in people don’t seem to have big effects on REM sleep and cataplexy. But these drugs affect the whole brain, and it’s possible that they are just not selective enough.

8 . 阅读下面短文，在空白处填1个适当的单词或括号内单词的正确形式 (1-3词)。

Traditional Chinese Medicine (TCM) has evolved over thousands of years. It is a comprehensive healthcare system     1     (root) in ancient theory and wisdom.

TCM came into being in the primitive (原始的) society, and its theory     2     (form) during the Spring and Autumn Period. During the Ming and Qing Dynasty, doctors tended to improve it despite pressure and difficulties.

    3     makes Chinese medicine distinct is its emphasis on the balance of vital energy within the body and the recognition of the body as     4     whole. In TCM, individuals often encounter a unique diagnostic (诊断的) approach,     5     involves considering not just symptoms but also the lifestyle of the person. Chinese medicine has a wide range of treatments,     6     (include) herbal medicine, acupuncture (针灸), and dietary therapy, to address both the symptoms and potential imbalances. In fact, TCM doesn’t only treat diseases; it promotes overall well-being by harmonizing the body, mind, and spirit. Medical     7     (professional) advocate that each individual is different, and their health conditions may originate from a     8     (combine) of factors.

Ancient wisdom and modern research have enabled Chinese medicine to find its place alongside Western medicine,     9     an increasing number of people seeking a comprehensive approach to healthcare. As Chinese medicine becomes more     10     (wide) recognized, it not only contributes to individual health but also enriches the global healthcare landscape.
