Welcome to your future life!
You get up in the morning and look into the mirror. Your face is firm and young-looking. In 2035, medical technology is better than ever. Many people your age could live to be 150,so at 40, you’re not old at all. And your parents just had an anti-aging(抗衰老的) treatment. Now, all three of you look the same age !
You say to your shirt , “Turn red.” It changes from blue to red. In 2035, “smart clothes” contain particles(粒子) much smaller than the cells in your body. The particles can be programmed to change clothes’color or pattern.
You walk into the kitchen . You pick up the milk ,but a voice says , “ You shouldn't drink that!” Your fridge has read the chip (芯片) that contains information about the milk , and it knows the milk is old . In 2035, every article of food in the grocery store has such a chip .
It’s time to go to work . In 2035, cars drive themselves. Just tell your “smart car” where to go. On the way , you can call a friend using your jacket sleeve . Such “smart technology” is all around you.

Getting rid of dirt, in the opinion of most people, is a good thing. However, there is nothing fixed about attitudes to dirt.
In the early 16th century, people thought that dirt on the skin was a means to block out disease, as medical opinion had it that washing off dirt with hot water could open up the skin and let ills in. A particular danger was thought to lie in public baths. By 1538, the French king had closed the bath houses in his kingdom. So did the king of England in 1546. Thus began a long time when the rich and the poor in Europe lived with dirt in a friendly way. Henry IV, King of France, was famously dirty. Upon learning that a nobleman had taken a bath, the king ordered that, to avoid the attack of disease, the nobleman should not go out.
Though the belief in the merit of dirt was long-lived, dirt has no longer been regarded as a nice neighbor ever since the 18th century. Scientifically speaking, cleaning away dirt is good to health. Clean water supply and hand washing are practical means of preventing disease. Yet, it seems that standards of cleanliness have moved beyond science since World War Ⅱ. Advertisements repeatedly sell the idea: clothes need to be whiter than white, cloths ever softer, surfaces to shine. Has the hate for dirt, however, gone too far?
Attitudes to dirt still differ hugely nowadays. Many first-time parents nervously try to warn their children off touching dirt, which might be responsible for the spread of disease.On the contrary, Mary Ruebush, an American immunologist(免疫学家)，encourages children to play in the dirt to build up a strong immune system. And the latter position is gaining some ground.
1.The kings of France and England in the 16th century closed bath houses because .
A. they lived healthily in a dirty environment.
B. they believed disease could be spread in public baths
C. they thought bath houses were too dirty to stay in
D. they considered bathing as the cause of skin disease
2.Which of the following best describes Henry IV’s attitude to bathing?
A. Approving. B. Afraid..
C. Curious D. Uninterested.
3.How does the passage mainly develop?
A. By providing examples.
B. By making comparisons.
C. By following the order of time.
D. By following the order of importance.
4.What is the author’s purpose in writing the passage?
A. To stress the role of dirt.
B. To introduce the history of dirt.
C. To call attention to the danger of dirt.
D. To present the change of views on dirt.
BEIJING - A research team led by Chinese scientists have discovered dietary modulation of gut microbiota（膳食干预肠道菌群）can alleviate both genetic and simple obesity in children.
The findings of the team, led by Zhao Liping with Shanghai Jiaotong University, Yin Aihua with the Guangdong province children's hospital, and Tang Huiru with Chinese Academy of Sciences, have been published on EBioMedicine, a renowned medical journal co-sponsored by Cell and The Lancet in July.
The team identified bacterial genomes specifically for producing obesity-related metabolites（代谢物）, and said an improved gut microbiota can significantly help to treat genetic obesity such as Prader-Willi Syndrome (PWS).
Beginning in childhood, PWS affected kids develop an insatiable appetite, leading to chronic overeating and obesity.
The scientists used a diet therapy with beneficial gut bacteria on trial patients and found considerable diminished appetite, weight loss and improved health conditions on the patients.
The paper concluded dysbiosis（失调）of gut microbiota is highly related with both genetic and simple obesity in children, implicating dietary modulation of gut microbiota a potentially effective treatment method.
1.Which of the following factors contributes to child obesity ?
A. dietary modulation of gut microbiota
B. beneficial gut bacteria
C. an improved gut microbiota
D. dysbiosis of gut microbiota
2.Which can replace the underlined word “diminished”？
A. unsatisfied B. increased
C. decreased D. good
3.Where is the passage extracted?
A. Medicine book B. Science book
C. Doctor’s instructions D. News report
4.Which might be the best title for the passage?
A. Chinese scientists discover treatment to child obesity.
B.The reasons for genetic obesity in children has been found.
C. Obesity-related research has been done by Chinese scientists.
D. An effective treatment to obesity has been found.
