Reading comprehension questions refer to a type of question in which reading materials are given first, and the mathematical content and method points are understood through reading, and can be applied, and then the questions raised later are solved to maintain the bacterial state in the body. What are the answers to balanced reading? I have compiled them below, welcome to read.

Maintaining the balance of bacteria in the body

Read the text below and complete questions 7 to 9

Humans are living things. If they want to live healthily, they must maintain the balance of bacteria in their bodies. After a person is born, various bacteria enter the human body one after another and become the body's lifelong companion.

It should be noted that the human body has hundreds of billions of cells, and the number of microbial cells it carries is 10 times that of human cells. Don’t think of foreign creatures as “aliens”; they are an indispensable part of the human body. Normal microbiota, immunity and metabolism are under the control of genetic genes in the human body and constitute the three pillars of life. They participate in the occurrence, development and decline of the physiological, biochemical, pathological, pharmacological and other functions and structures of the human body.

Research shows that normal microbiota are directly involved in the collective biological defense barrier structure. One is chemical barrier. Active substances such as acetic acid and propionic acid, products of normal flora metabolism, form chemical barriers such as acid shields to resist the invasion and damage of pathogenic bacteria. The second is biological barriers. The normal flora living on the mucosa or panel can form a biofilm-like structure with individual specificity. The flora interact with each other, coordinate with each other, and interact with each other. *** The mucosal immune system of the panel enhances the body's immune function and plays a role. It can inhibit the colonization, space occupation, growth and reproduction of passing bacteria or pathogenic bacteria.

To sum up, people cannot live without bacteria. However, what is worrying is that many adverse factors have more or less affected the balance and stability of the microecology, leading to microecological imbalance. People abuse broad-spectrum antibiotics, hormones and immunosuppressants, and use modern examinations irrationally, which can cause imbalances in the human body's bacterial flora and endanger health. In particular, the indiscriminate bombardment of antibiotics kills bacteria. Old diseases are not eliminated, but new diseases appear again, causing headaches for doctors and suffering for patients. For this reason, scientists proposed the idea of ??eating fungi and developed probiotics, a microecological regulator.

After getting sick, let bacteria treat you. This is today's brand-new therapy. "The era after antibiotics will be the era of live bacteria and probiotics." This is what Professor Wei Xi, a famous Chinese microbiologist, said in 1981.

B. The human body is inseparable from microbial cells, which participate in the occurrence, development and decline of various functions and structures of the human body.

C. People use antibiotics, hormones and modern examinations, which cause an imbalance of human bacteria and endanger health.

D. People need to change their mindset and switch from relying mainly on antibiotic treatment to mainly relying on probiotic treatment after getting sick.

9. According to the information provided in this article, one of the following statements that does not conform to the original meaning is******

"Maintaining the Balance of Bacteria in the Body" Reading Answers

7.C. From the second paragraph, we know that "they" are relative to "the body's own cells", They are microbial cells carried by the human body's own cells, which are called "foreign organisms".

8.C. From the original text, we learned that it is "abuse" and "unreasonable use" that will produce "health-endangering" consequences.

9.B. According to the original meaning, an imbalance of human body bacteria will endanger health and does not "mean the death of life."
