Winning a remarkable science award is really a big deal, especially if you are 12 years old. But Shanya Gill, a middle schooler from San Jose, California, won the top award in the Thermo Fisher Scientific Junior Innovators Challenge for designing a fire detection system that is superior to existing ones, as stated in the press release.
“The top winners have exhibited boundless curiosity,” Maya Ajmera president and CEO of Society for Science, said in the press release. “Their remarkable research not only reflects their talent but also paves the way for an exciting new future.”
Shanya’s inspiration came after a fire destroyed a restaurant in her neighborhood during the summer of 2022, reported The Washington Post. “I had never really experienced something like that before,” she told The Washington Post about the early morning fire at Holder’s Country Inn, which started in the kitchen. “They had smoke detectors. and yet it still burned down,” she added.
After she studied fire statistics, Shaya spent over a year developing a fire detection system that she believes could have prevented the fire. Unlike traditional smoke detectors that sense active fires from the smoke in the air, Shanya’s thermal (热的) imaging device is designed to stop fires from occurring.
With a thermal camera and a Raspberry Pi, a tiny computer the device detects when a heat source has been left unattended for ten minutes and sends a text message warning. Creating the prototype(原型) was difficult and the hardest part was the programming, “I had two designs, and my first design completely failed. It was a really big challenge I had to go through.” she said. The final device outperforms smoke detectors in speed and accuracy. Shanya wants to bring the costs down to make it even more common than hardwired smoke detectors.
“Shanya saw a problem, went after it and tried to solve it, and that’s what we need to encourage with all young people,” said Ajmera. She also highlighted the significance of supporting individuals, especially girls and kids of color, in STEM fields, as research indicates that many young people drop out of these areas.
1. What can we learn about Shanya from the first two paragraphs?| A．She gained a lot of money in the award. | B．She showed a curious nature as a schooler. |
| C．She set a big stage for young people her age. | D．She was junior to other winners in performance. |
| A．Her desire to win the science award. | B．Her experience of a destructive fire. |
| C．Her interest in computer programming. | D．Her goal to improve STEM education for girls. |

Ali and his younger sister, Zahra, lived with their parents in a poor neighborhood. Their mother was very sick and their father was struggling to find a job, and they had only a little money with which to buy food. As they had not paid the rent for several months, the landlord was breathing down their necks.
One day, Ali took Zahra's shoes to a shoe repairman to be fixed, but he lost them on the way home. It wasn’t until he got home that he realized he had lost the shoes. He was afraid that his parents would be angry and disappointed, so he begged his sister to keep it a secret. Zahra agreed and the two decided to share Ali’s running shoes. Zahra's school hours were in the morning, so she would wear them first. After school, she would rush back and give them to Ali. He could then run to his school, which began in the afternoon. Although he ran as fast as he could, Ali often arrived late and was warned by the school.
Ali heard about a long distance race that was held for the boys in the city.When he learned that the third prize was a new pair of shoes, he decided to take part. He ran home excitedly and promised his sister that he would win her the new shoes.
The day of race arrived. Ali had a strong start, but halfway through the race he began to get tired and his legs began to ache. Getting more and more exhausted he thought only of Zahra and his promise to her. Dreaming of the new shoes he would win for his sister gave him strength, and he stayed right behind the two fastest runners, determined to finish third. Suddenly, as the finish line drew near, another runner collided(碰撞) with Ali from behind and he crashed to the ground.
Ali looked up and saw the other boys rushing ahead.

Scientists have shown how plants can protect themselves against genetic (基因的) damage caused by environmental stresses. The growing tips of plant roots and shoots have an in-built mechanism (机制) that spells cell death if DNA damage is detected, avoiding passing on faulty DNA.
Plants have small populations of stem cells (干细胞) at the tips of their roots and shoots, which enable them to continuously grow and produce new tissues throughout their lifetime. These stem cells serve as ancestors for plant tissues and organs. However, any genetic faults present in the stem cells will continue to exist and be passed on permanently throughout the plant’s life, which could last thousands of years.
Given the critical role of stem cells and their exposure to potentially dangerous environments at the growing tips of roots and shoots, safeguards are necessary to prevent stem cell faults from becoming fixed. Researchers Nick Fulcher and Robert Sablowski, funded by the Biotechnology and Biological Sciences Research Council, aimed to uncover these protective mechanisms. Through experiments involving X-rays and chemicals, they discovered that stem cells were more sensitive to DNA damage compared to other cells.
When DNA damage occurs, the cells have the capacity to detect it and cause programmed cells to die, preventing the propagation of the damaged genetic code to the rest of the plant tissues. This process has similarities to the safeguard mechanism found in animal cells, which has been broadly studied due to its relevance in preventing cancer.
The identification of a similar protective system in plants is of great interest in the field of plant development. It also helps scientists develop plants that can better handle environmental stress. So knowledge of how plants deal with these stresses is of fundamental significance to agricultural science’s response to climate change.

| C．To enhance plant growth and nutrient intake. | D．To stop genetic faults in stem cells passing on. |
| A．They are relatively abundant in quantity. | B．They are resistant to environmental stresses. |
| C．They make quick response to DNA damage. | D．They have the ability to repair damaged DNA. |
| A．Spread. | B．Change. | C．Existence. | D．Self-repair. |
| A．The way of dealing with climate change on the earth. |
| B．The significance of identifying the protective system in plants. |

8 . The average cost of an iPhone has climbed up, and even the most affordable Android devices come with arising price.
Remove unnecessary apps and photos.
When the storage and capabilities (能力) of the smartphone are being maxed out, the phone will become much less responsive.
Put your phone on the charger (充电器) when it reaches a battery life of 75 percent. Waiting until the battery life drops to 25 percent will dramatically reduce its ability to receive and hold a change. Using up your battery and then charging it back to 100 percent is a bad idea. Your phone will last a lot longer if you charge it for a few minutes off and on throughout the day.
Don’t exercise carrying your smartphone with you.
Some phone users have experienced water damage issues as a result of sweating while their phone was in their pocket or fastened to their arm. This problem becomes worsened by the unwillingness of the phone company to cover even minimal water damage under their guarantee program.
Take advantage of cloud storage.
| A．Power down regularly. |
| B．Keep the battery in good condition. |
| C．But it may not be in your best interests to use them. |
| D．It often convinces people to upgrade before they truly need to. |
| E．It helps your phone never become overloaded with too much data. |
| F．So it does not make sense to take the risk of harming it with sweat. |
| G．Are you wasting your money by replacing your mobile phone annually? |
China is widely known for its ancient civilization which has continued all the way through into modern times,
At the beginning, written Chinese was a picture-based language, dating back several thousand years to the use of longgu-animal bones and shells on which symbols were carved by ancient Chinese people. Some of the ancient symbols can still be seen in today’s hanzi.
By the Shang Dynasty (around 1600-1046 BCE), these symbols
Emperor Qinshihuang united the seven major states into one unified country where the Chinese writing system
Today, the Chinese writing system is seen in the development of Chinese characters as an art form,
