One of the most important recent medical breakthroughs has been the impact of gut flora（肠道菌群）on overall health. This dynamic mix of bacteria in the digestive tract（消化道）may affect everything from obesity to asthma（哮喘）．

The Gut-Mood Link

Anyone who's ever experienced "butterflies" in his or her stomach knows that the gut and the brain are connected. But until recently, scientists hadn't realized that the trillions of bacteria in our digestive tract may be driving the relationship.

One recent experiment suggests that you can control calm. Canadian researchers gave healthy mice a mixture of antibiotics, which change the makeup of GI-tract（胃肠道）bacteria. Over two weeks, some animals became more anxious and some less, depending on which drugs they received. In another study, when gut bacteria from calm mice were transferred to anxious mice, the jittery（紧张的）creatures seemed less nervous.

UCLA professor Kirsten Tillisch, doctor of medicine, recently had healthy women eat a yogurt

rich in certain types of "good" probiotic（益生菌的）bacteria. Two 'Control groups ate yogurt without such bacteria or ate nothing. Brain scans of the probiotic-yogurt eaters indicated changes in regions that could be associated with a less-anxious response in fearful or stressful situations compared with the control groups.

Scientists are even exploring whether gut microbes（微生物）might treat some brain disorders. A new study in Cell found that mice with features of autism（自ICJ症）given a type of bacteria in healthy human GI tracts exhibited less autism-like behavior. In a recent case report, a Boston ps. chiatrist says a course of certain probiotics and antibiotics helped relieve a patient's compulsive disorder. -We tend to focus on how your mood affects your body from the top down, not the bottom up," says Dr. Tillisch. "Now we know that the gut affects how your brain responds to the environment- it's a remarkable change in thinking.”

How Bacteria Talk to the Brain Scientists aren't sure how gut flora affect brain chemistry. One theory is that the bacteria access pathways along the nerve, the main highway in the nervous system that links the brain to the gut. Another is that the bacteria influence the immune system, releasing chemicals that affect conditions like depression. Finally, researchers believe that bacteria produce or affect the metabolism（新陈代泻'i) of chemicals, which change brain function.

Dr. Tillisch told me that patients always ask which probiotics will lift their mood．Her answer:

"We don't know yet, but we hope to one day." In the future, patients might receive probiotics or transplant（移植） in which bacteria from the gut of a healthy person are transferred to the gut of a sic': one-to prevent or treat mental health issues. But these approaches are years away from primary time．Until then, a diet rich in fruit and veggies helps cultivate（培养）better-balanced microbes than a typical Western diet high in animal and processed products. Avoiding unnecessary antibiotics, particularly in early childhood, may also establish healthier gut bacteria.

1. According to the passage, gut bacteria might help us in many ways EXCEPT＿_．

A. lightening our mood B. treating autism

C. relieving depression D. transplanting gut flora

2.The missing sentence "Everyday foods may also affect the composition of gut bacteria, and in

turn, brain chemistry." could be put before＿_·

A. Paragraph 2 B. Paragraph 3

C. Paragraph 4 D. Paragraph 5

3.Which of the following can be the best subtitle for the last paragraph?

A. Cultivating a Happier Gut

B. Growing Bacteria in the Future

C. Balancing Microbes and Diet

D. Living a Happy Healthy Life

Recently, online hike-sharing has become the new favorite in China. In major cities, bikes in, yellow, orange, blue, white and green, can be seen almost everywhere on the street. It seems that these bikes appeared suddenly, adding a new beautiful scenery to Chinese cities.

Both the market and the public welcome online bike-sharing, but is it really a promising business? Well, it depends. After all, online bike-sharing platforms can never get away with huge operating cost and uncertain government policy.

Some theorists might say that online bike-sharing platforms can earn a fortune simply through deposit. Since users will always need to rent bikes, their deposit will always be kept to online bike-sharing platforms.

However，although online bike-sharing platforms may be able to use the deposit for other purposes at the primary stage, they will have to set up a special account, so that the deposit shall be used specially for its designated (指定的) purpose. As the market gets increasingly mature, they will have to do so whether to be responsible for users or in consideration of possible government regulations.

Now that online hike-sharing platforms can，t make profit through deposit，how can they become profitable as fiercer market unfolds? Although Hu Weiwei, CEO of Mobike, stated in an article that she would take Mobike as charitable(慈善的) project if she failed, running a startup is absolutely different from managing a charity organization. After all , she has to pay back investors’ billions of investment(投资).

To make profit, online bike-sharing platforms might have toincrease rent fee for each trip, just as Didi did

From this aspect, it might be a really good business. If we consider full screen ads fee, recommendation fee for business owners, etc. , its annual income might reach at least RMB 15 billion. If we consider the huge operation cost, including bike repairs，bikes’ service life and labor cost, there might not be much net profit left. After all, offline operation cost has always been an unbearable burden for such internet plus mode-based startups.

1.How does the author feel about the future of online bike-sharing platforms?

A. Optimistic.　　 B. Doubtful.

C. Hopeful.　　 D. Secure.

2.How do some theorists think online bike-sharing platforms can make money?

A. Through advertisements.　　 B. Through services.

C. Through deposit.　　 D. Through investment.

3.How should deposit be dealt with when the market is mature according to the author?

A. Used for other purposes.　　 B. Kept in a special account.

C. Used for charity.　　 D. Left aside to the users.

4.What does the underlined word “unfolds” mean in the passage?

A. Shrinks.　　 B. Spreads.　　 C. Shows.　　 D. Develops.
