How the Venus Flytrap Closes

捕蠅草是如何閉合的


Introduction

Scientists have a new idea about how the Venus flytrap closes its leaves quickly.

科學家對於捕蠅草如何快速閉合葉片有了新見解。

Main Body

The plant closes very fast. For a long time, people thought water moved inside the plant to make it close. But water moves too slowly for this.

這種植物閉合速度非常快。長期以來,人們認為是水在植物內部移動才使其閉合。但水的移動速度太慢,無法解釋這種快速度。

Now, scientists found a different reason. The walls of the plant cells become soft. This happens in one second. This softness makes the trap snap shut.

現在,科學家發現了另一個原因。植物細胞的細胞壁會變軟。這在一次秒內就會發生。這種柔軟度使得陷阱能迅速閉合。

Some scientists like this new idea. Other scientists do not agree. They say the study is not complete. They want to know more about how the plant opens again.

有些科學家認同這個新觀點。而有些科學家則不同意。他們認為研究尚未完整,並想進一步了解植物如何再次開啟。

Conclusion

The plant closes because its cell walls get soft, but scientists do not know exactly why this happens.

植物之所以閉合是因為其細胞壁變軟,但科學家還不確定具體原因。

💡 The 'Opposite' Trick

In this text, we see how to switch a thought from YES to NO. This is a key way to move from A1 to A2 English.

The Pattern: Statement \rightarrow But \rightarrow Opposite Statement

From the text: "People thought water moved... \rightarrow But water moves too slowly."

How to use it: Use 'But' to stop a wrong idea and give the right one.

  • Wrong: I think it is sunny. \rightarrow But it is raining.
  • Wrong: He is a doctor. \rightarrow But he does not work in a hospital.

📝 Word Power: Speed

Notice how the author describes time. Learn these three levels of speed:

  1. Very fast (The plant closes)
  2. In one second (The walls become soft)
  3. Too slowly (Water moves)
