16-year-old Lin Kai has been interested in biology since primary school.He often reads books about bioengineering and watches science documentaries in his spare time.When he saw the local river was polluted by food waste last year,he decided to use bioengineering knowledge to solve the problem.
At first,his parents and teachers thought it was too difficult for a teenager—they said he lacked professional equipment and knowledge.But Lin Kai didn’t give up.He asked his biology teacher for help and joined the school’s science club.He spent six months researching and experimenting,trying to culture a kind of bacteria that could decompose food waste quickly.He failed many times:the bacteria didn’t work well,or they died easily in different temperatures.
With the guidance of his teacher and the help of bioengineering online courses,Lin Kai finally succeeded in March 2026.His developed bacteria agent can decompose 80%of food waste in three days,and it is non-toxic to the environment.The local environmental protection bureau praised his invention and decided to test it in the community.When asked about his success,Lin Kai said,“Bioengineering is not a distant subject;it is a tool that can solve real life problems.As long as we keep learning and trying,teenagers can also make contributions with science.”
24.Why did Lin Kai decide to research bioengineering bacteria agent
A.Because he wanted to win a science competition
B.Because he wanted to solve the river pollution problem
C.Because his teacher asked him to do so for homework
D.Because his parents encouraged him to study bioengineering
25.What does the underlined word“decompose”in Paragraph 3 probably mean

B.Lin Kai’s invention has been widely used in the community
C.Teenagers can use science to solve real life problems with efforts
D.The bacteria agent is toxic to the river environment
27.What is the best title for the text
A.A Teenage Scientist’s Bioengineering Dream Comes True
B.The History of Bioengineering Technology Development
C.How to Culture Bacteria in the Bioengineering Lab
D.A Famous Bioengineer and His Great Inventions
C
In 2026,bioengineering has stepped out of the lab and become an important part of people’s daily life,bringing great changes to food,medical care,environmental protection and other people’s livelihood fields.This technology,which combines biology,engineering and computer science,is no longer a distant high technology,but a practical tool to improve people’s quality of life.
In medical care,bioengineering has made the greatest progress.Artificial organs developed by bioengineers,such as artificial heart valves and artificial skin,have helped millions of patients.Gene editing technology has also been used to treat some genetic diseases that were incurable before,giving new hope to patients and their families.What’s more,bioengineering has accelerated the development of new medicines,making the research and development cycle of some medicines shortened from years to months.
In agriculture,bioengineering has improved crop production and quality.Genetically modified crops with insect resistance and drought resistance can grow well in poor conditions,which solves the food shortage problem in some areas.Bioengineering also helps develop green pesticides,which are non-toxic to the environment and protect the ecological balance.
In environmental protection,like Lin Kai’s invention,bioengineering technologies such as microbial decomposition and bioremediation are widely used to treat water and soil pollution.These technologies are more environmentally friendly and efficient than traditional physical and chemical methods,and they have become an important way to protect the ecological environment.
Of course,bioengineering is still developing,and there are still many problems to solve.But with the efforts of scientists,it will bring more benefits to human society in the future.
28.What is the main idea of Paragraph 2
A.The progress of bioengineering in medical care
B.The development of gene editing technology
C.The research cycle of new bioengineering medicines
D.The kinds of artificial organs developed by scientists
29.How does bioengineering help in agriculture
A.It makes traditional pesticides more toxic
B.It develops crops with better resistance and yield
C.It solves the food shortage problem all over the world
D.It makes crops grow only in good natural conditions
30.We can infer from the text that______.
A.Bioengineering has no problems or risks at all
B.Bioengineering is only used in the scientific lab now
C.Bioengineering makes people’s life more convenient and healthy
D.Traditional environmental protection methods are better than bioengineering
31.What is the author’s attitude towards the future of bioengineering
A.Pessimistic B.Optimistic C.Doubtful D.Unconcerned
D
The rapid rise of bioengineering has brought great benefits to human society,but it also raises many ethical and social problems.While we are enjoying the convenience and progress brought by this technology,we must think about how to standardize its use and avoid potential risks.This is a problem that the whole society needs to face and solve in 2026 and even in the future.
One of the biggest ethical problems of bioengineering is gene editing technology.If gene editing is used on human embryos,it may change the human gene pool and bring unknown risks to human evolution.Some people may even use gene editing technology to pursue“perfect babies”,which will break the natural fairness of human society.In addition,the use of artificial organs and biological cloning technology also has ethical disputes:who has the right to use these technologies Is it fair for only the rich to afford high-tech bioengineering medical treatment
Besides ethical problems,bioengineering also needs strict legal rules.At present,some bioengineering technologies are developing too fast,and the relevant laws and regulations can not keep up with their development speed.This may lead to the misuse of some technologies,such as the illegal use of gene editing to make harmful biological products,or the random discharge of bioengineering experiment waste that pollutes the environment.
However,we can not deny the great value of bioengineering because of these problems.The key is to find a balance between technological development and ethical rules.We need to set strict international ethical standards and perfect relevant laws and regulations to standardize the research and use of bioengineering.At the same time,we also need to strengthen the science popularization of bioengineering,let people understand this technology correctly,and form a scientific attitude towards it.
For teenagers,learning bioengineering knowledge is not only to master a new technology,but also to establish a correct view of science and technology—technology is for the benefit of human society,and it must be used under moral and legal constraints.
32.What is the main problem the author discusses in the text
A.The rapid development of bioengineering in all fields
B.The ethical and social problems brought by bioengineering
C.The wide application of bioengineering in daily life
D.The way teenagers learn bioengineering knowledge
33.Why is gene editing on human embryos a big ethical problem
A.Because it is too expensive for ordinary families
B.Because it may change the human gene pool and bring unknown risks
C.Because it can only cure a few genetic diseases
D.Because it will slow down the development of bioengineering
34.What can we conclude from the text
A.Bioengineering has no value and should be stopped
B.We should balance bioengineering development and ethical rules
C.The laws and regulations of bioengineering are perfect now
D.Only scientists need to learn about bioengineering ethical rules
35.How is the passage mainly developed

I joined the school’s bioengineering club at the beginning of 2026,because I was deeply interested in bioengineering after visiting a science exhibition.My first task in the club was to do a simple experiment:culturing a kind of bacteria that can help plants grow better.The teacher said it was a basic experiment,but it was not easy for a beginner like me.
I followed the teacher’s steps carefully:prepared the culture medium,added the bacteria,and put it in a constant temperature box.I thought it would succeed easily,but things didn’t go as I expected.Three days later,I found the bacteria didn’t grow at all—they were dead.I felt very disappointed and even wanted to quit the club.I thought I was not suitable for learning bioengineering and doing scientific experiments.
My club teacher noticed my sadness.She came to me and said,“Failure is a common thing in scientific experiments.Every bioengineer has experienced countless failures before success.You need to find the reason for the failure and try again.”With her encouragement,I decided to find out why the experiment failed and do it again.I checked all the steps and found that I had made a mistake in the temperature of the constant temperature box.
