HIV 很難對付，因為它變化很大。科學家現在使用一種特殊方法。這個方法能喚醒體內罕見的細胞，而這些細胞可以產生強效抗體。
Scientists tested this on monkeys. More than half of the monkeys made these strong antibodies. Some monkeys had very high levels of protection in their blood.
科學家在猴子身上進行了測試。超過一半的猴子產生了這些強效抗體，有些猴子的血液中具有極高水平的保護力。
Other scientists used a new protein called CAP256.OPT4. This protein works much better than old versions. In a new test, 90% of the monkeys could fight many types of the virus.
其他科學家使用了一種名為 CAP256.OPT4 的新蛋白質。這種蛋白質的效果比舊版本好得多。在一次新測試中，90% 的猴子能夠對抗多種類型的病毒。
Conclusion
These tests on monkeys worked well. Now, scientists have a plan to try this for humans.
這些在猴子身上進行的測試效果良好。現在，科學家已經計劃將其應用於人類。

The 'Better' Pattern
In this text, we see how to compare things using Better and More. This is key for A2 English.
1. Comparing Quality
- Old version New version (Better)
- "This protein works much better than old versions."
- Rule: Use Better when one thing is superior to another.
2. Comparing Quantity
- Few More
- "More than half of the monkeys..."
- Rule: Use More than when the number is higher than a specific limit.
