New Way to Kill Bad Bacteria
殺死有害細菌的新方法
Introduction
Scientists found a special group of genes in bacteria. These genes make a team of medicines to kill other bacteria.
科學家在細菌中發現了一組特殊的基因。這些基因能產生一組藥物來殺死其他細菌。
Main Body
In the past, scientists looked for one medicine at a time. Now, they found a big group of four medicines. These medicines work together. They stop the bacteria from using biotin. Biotin is a vitamin that bacteria need to live.
過去，科學家一次只尋找一種藥物。現在，他們發現了一個由四種藥物組成的大群組。這些藥物會協同工作，阻止細菌使用生物素。生物素是細菌生存所需的一種維生素。
The scientists tested these medicines in a lab. They used a mouse with a bad infection. The team of medicines worked better than one medicine alone. It killed bacteria that other drugs cannot kill.
科學家在實驗室中測試了這些藥物。他們使用了一隻患有嚴重感染的小鼠。這組藥物的效果比單一藥物更好，能夠殺死其他藥物無法殺死的細菌。
Many types of these bacteria have the same genes. This means nature made this team of medicines a long time ago. This helps the medicines work better and stops bacteria from fighting back.
許多類型的這類細菌具有相同的基因。這意味著大自然在很久以前就製造了這組藥物。這有助於提高藥效，並防止細菌產生抗藥性。
Conclusion
This discovery helps scientists make new medicines. These medicines can fight very strong bacteria.
這項發現有助於科學家開發新藥，可用於對抗非常強大的細菌。
Vocabulary Learning
💡 THE 'HELPING' VERBS
Look at how we describe what things can or cannot do in the text. This is a key bridge to A2 English.
The Pattern:
Can / Cannot + Action (Base Word)
Examples from the text:
- Other drugs cannot kill They are not able to do it.
- Medicines can fight They have the power to do it.

If you want to describe a skill or a limit, use this simple map:
Positive I can speak English.
Negative I cannot speak Japanese.
Note: In the article, we see that nature is strong because the medicines can kill bacteria that usually hide from one single drug.
