You've probably seen this scene before.

A person lines up two pieces of wood, grabs a screwdriver, places a screw, and twists it in place.

Suddenly, those two pieces become firmly locked together.

But how does a simple twist create such a strong grip?

A screw is a type of simple machine.

It looks like a nail with grooves called threads spiraling around it it.

When you turn the screw, these threads help push or pull the screw through a material, like wood or plastic, with much less force than if you tried to shove it straight in.

We use screws more often than you might realize.

Jar lids twist on and off using screw threads.

A light bulb fits into its socket the same way.

Even a car jack uses a large screw to lift a heavy vehicle off the ground.

Underneath these grooves is a clever concept, an inclined plane wrapped in a spiral.

By turning the screw, you spread out the effort over a longer distance, making it easier to secure or lift objects.

So next time you see a screw at work, whether it's turning on a faucet or grinding pepper, remember it's one of the most effective simple machines around.

It's a small invention with a big impact on our everyday tasks.

什麼是跟讀法？

跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
