A woman in Zhejiang Province has been told by the doctor that she might develop “dead butt syndrome” (死臀综合征) due to long periods of sitting, according to a report by Guangming Net on Wednesday. The 26-year-old woman, who prefers to be called Dai, had been experiencing discomfort in her lower back for the past two months. The discomfort later became unbearable pain during extended periods of sitting.

News of the incident quickly gained attention on Sina Weibo. Some users humorously commented that while some people may be alive, their butts have already “died”. Others expressed concern about their own inactive lifestyles and the possibility of developing the syndrome.

“Dead butt syndrome” mainly happens when the gluteus medius (臀中肌), one of the three main muscles in the buttocks, weakens due to long periods of sitting. This weakening can damage the muscles’ability to work properly, leading to poor shock absorption and reduced motion control of the hip and leg. The syndrome is becoming a more common disease without people’s noticing.

Medical professionals have offered precautionary (预防的) measures for the syndrome, stressing the importance of staying physically active. For individuals who sit for long periods, it is recommended to stand up and stretch the body periodically, walk around, and keep the gluteal muscles active throughout the day.

A simple rule to follow is to stand up and move for at least 10 minutes every hour of sitting to reactivate the gluteal muscles and prevent them from becoming “inactive”.

There are three simple self-diagnosis (自我诊断) steps for the syndrome: flat and floppy butts, discomfort in the waist, hips, and knees after long time of sitting, and an inability to keep the upper body upright while performing a deep squat (蹲) with both hands extended overhead. If someone shows all these symptoms, there is a possibility that they have developed the syndrome. Furthermore, if individuals experience worsening lower back pain after long periods of sitting, seeking professional medical help is advisable.

1. Why is the woman’s case mentioned in paragraph 1?
A.To introduce the topic.
B.To make the text interesting.
C.To attract the readers’attention.
D.To explain what dead butt syndrome is.
2. How can we prevent ourselves from developing “dead butt syndrome”?
A.By avoiding sitting when at work.
B.By making our gluteal muscles active.

D.By standing up and move every 10 minutes.
3. What’s the main cause of this syndrome?
A.The poor shock absorption.
B.The damaged ability to walk.
C.The weakened gluteus medius.
D.The reduced motion control of the leg.
4. What’s the best title of the text?
A.Dead Butt Syndrome—a Hidden Health Killer

【推荐1】I used to think that the most effective way to resist depression (抑郁) was to have my heart set on happiness. If you valued happiness instead of sorrow as your goal, I thought, one would not suffer from depression.

However, a study, carried out among students living in the UK, found those who said they valued happiness extremely highly tended to show greater signs of depression.

Vogt and colleagues presented 151 students, the majority of them female, with a series of online questionnaires, These examined attitudes from how much they valued happiness to how much their emotions affected them, how easy they found it to put aside emotions, and their levels of depression-related symptoms.

The results, published in the Journal of Happiness Studies, reveal that those who valued happiness more had higher scores for symptoms of depression. The reason is in part because individuals become distracted by their feelings and a lower ability to reframe thoughts or experiences. It is also in part because. of bottling up emotions. “Suppression is not considered a successful emotional regulation strategy because when you try not to think of something you think of it all the time," said Vogt.

While Vogt said the study cannot prove that valuing happiness too much causes symptoms of depression, she said it was highly possible. She also noted that in Russia and east Asian countries the opposite trend had been found.

However, the study has limitations - including that it mainly involved women and did not account for the health or socioeconomic status or participants, although all were young and at university.

1. What did the study find?
A.If you value happiness, you won't get upset.
B.The goal of happiness leads to depression.
C.Negative :emotions affects one's happiness.
D.Female college students are easier to become depressed.
2. What are the reasons causing depression in people according to the passage EXCEPT?
A.They are distracted by their feelings.B.They fail to adjust their thought.
C.They welcome every kind of emotions.D.They think about happiness all the time.
3. What does the underlined word “suppression” mean?
A.expressionB.hiding
C.valueD.happiness
4. What is the author's attitude towards the study?
A.objectiveB.indifferent
C.supportiveD.critical

文章大意:这是一篇说明文。文章主要说明了研究人员发现了两个可能与阿尔茨海默病有关的新基因,介绍了他们发现这两个基因的方式、什么是阿尔茨海默病以及这一发现的重要意义。

【推荐2】A research team led by Chunshui Yu and Mulin Jun Li of Tianjin Medical University has discovered two new genes potentially involved in Alzheimer’s disease. They identified them by exploring which genes were turned on and off in the hippocampus of people who suffered from the disease. The team’s new findings are published on February 25th in PLOS Genetics.

Alzheimer’s disease is a type of brain disorder that causes problems with memory, thinking and behavior. This is a gradually progressive condition. The hippocampus, part of the brain involved in memory, is one of the first regions to sustain damage. To better understand which genes contribute to the progression of this heritable disease, the researchers identified genes expressed at higher or lower levels in the hippocampus of people with Alzheimer’s disease compared to healthy brains. They identified 24 Alzheimer’s-related genes that appear to have an effect through the hippocampus, using previous genomic and hippocampus gene expression data. Many genes were already known to contribute to the disease, such as APOE, but two were unknown, PTPN9 and PCDHA4. Additionally, several are involved in biological process related to Alzheimer’s disease, such as cell death.

The research team further validated their findings by comparing gene expression for the two dozen genes to images of the individuals’ brains. In Alzheimer’s disease, damage and loss of neurons causes the hippocampus to decrease, which can be measured through medical imaging. The researchers established that expression of two of the genes is related to the size of the hippocampus of Alzheimer’s disease.

Overall, the new findings improve our understanding of the genetic and cellular mechanisms that cause Alzheimer’s disease. The next step will be to investigate the roles of the two novel genes and how they contribute to this harmful disease.

1. How did the research team find the two genes related to Alzheimer’s disease?
A.By closing the hippocampus of people.
B.By exploring the switch state of the genes.
C.By turning on and off the genes of the patient.
D.By discovering genes in the hippocampus of people.
2. What does the underlined word “validated” mean in Paragraph 3?
A.Reported.B.Conducted.C.Confirmed.D.Exposed.
3. What can we infer about the size of the hippocampus in Alzheimer’s disease.
A.It comes in a smaller size.B.There is no way to measure its size.
C.It results in damage and loss of neurons.D.It helps to identify Alzheimer’s disease.
4. What is the main idea of this passage?
A.It is vital to continue the study of Alzheimer’s disease.
B.The cause of Alzheimer’s disease has been found.
C.The Alzheimer’s disease will be cured soon by the research team.
D.Two novel genes likely linked to Alzheimer’s disease have been discovered.

【推荐3】Something strange was happening inside Anne' s home. During the summer of 2014, twins Gavin and Garrett, then three, each had skin rash (疹子) that wouldn't go away. 14-year-old J. D. had stomach pains so severe that he couldn’t climb the stairs,but tests found nothing wrong. By winter, the family's health problems were getting worse.

One day, Anne found brown water flowed out of the tap. Worried that the water was polluted, the family began using bottled water for cooking,drinking, and bathing.

In January 2015,the city of Flint sent out a notice stating that the water supply—which had been switched, in a cost-cutting measure, from the Detroit water system to the Flint River the previous spring—contained high levels of trihalomethanes (三卤甲烷). The notice warned that elderly people might be at risk for health problems but emphasized that the water was otherwise safe to drink.

Shocked, the self-claimed "stay-at-home mom turned water warrior" researched the water supply and searched the Internet for information that she distributed to city officials, listing the side effects of exposure to trihalomethanes. Then she urged her neighbors to attend city council meetings, where they shared their health problems. Still, officials insisted the water was safe to drink. So Anne demanded that the city test her water. The results were disturbing. The trihalomethanes were the least of her problems. The tests included that the lead levels in her water were nearly seven times the legal amount.

Anne had her children tested for lead. All the kids showed lead poisoning. She requested Flint's water quality reports and discovered that the city wasn't applying the proper corrosion (腐蚀) control standards to its pipes; the standards prevent the metal in pipes from leaking into the water.

1. How did Gavin suffer from the disease?
A.His stomach hurt so much that he couldn’t' climb the stairs.
B.He had rash on his skin which wouldn’t' disappear.
C.His disease got too ill for him to get any medical tests.
D.He had weak eyesight and couldn't go to school,
2. Why did the city of Flint change its water supply?
A.The Detroit water system had been polluted.
B.The Flint River was made clean a year ago.
C.They wanted to cut the cost of water supply.
D.The Flint River always has brown water.
3. The test of the water from Anne' s home showed that          .
A.her family had the worst of the trihalomethanes pollution
B.the water from her tap was safe to use except for drinking
C.her family was located in the most polluted part of the city
D.there was something more serious than the trihalomethanes
4. The water problem was caused by
