英語閱讀訓練：那些重要的冷知識

大家在學習英語的時候一定要好好練習英語的閱讀，平時如果能夠在閱讀中學到更多的知識就更好了。比如有的人前一刻還在河水中自在地游泳，下一刻可能就被一股暗流捲走。我們應該注意學習安全知識，做好防範，規避風險。這篇英語文章希望可以幫助大家。

01 被瓦礫掩埋

If you ever find yourself buried in rubble and can't get out, don't yell. You'll end up just wasting energy and losing your voice. What you should do is grab something and start tapping in intervals of three. Humans are great at noticing patterns and the rescuers will start to move towards that. Once you hear them, then you can start yelling.

如果你發現自己被埋在瓦礫中出不來，不要大喊大叫。這樣最終只會讓你的精力耗盡，發不出聲來。你應該做的是抓住某樣東西，三次一間隔的開始敲擊。人類非常善於發現有規律的聲音，救援人員會開始朝着你的方向搜救。一旦你聽到他們的聲音，就可以大聲呼救了。

02 龍捲風

If a tornado looks like it's not moving, that means it's heading towards you.

如果龍捲風看起來沒有移動，那就意味着它正向你襲來。

03 落入冷水

If someone falls in cold water and is close to hypothermia, don't put them next to a fire. They need to be warmed up slowly. Otherwise it could be potentially fatal and they could experience something called afterdrop. And this is due to the fact that your blood flow cannot adapt quick enough to that change from extreme cold to extreme hot.

如果有人落入冷水中，接近失溫，不要把他們安置在火旁邊。需要慢慢讓他們熱起來。否則可能帶來致命後果，使他們在復溫時核心體溫進一步下降。這是因爲血液流動沒那麼快，能夠讓身體很快地適應從極冷到極熱的變化。

04 災後蓄水

Before natural disasters make sure to fill your tub up and your sink with water that is clean. According to the FDA, after major disasters, water's either cut off or heavily contaminated. So it's important to make sure you have enough supply of clean water.

在自然災害發生之前，一定要把你的浴缸和水槽裝滿乾淨的水。美國食品和藥物管理局表示，在發生重大災難後，水源要麼被切斷，要麼被嚴重污染。所以確保你有充足的乾淨水很重要。

05 雙肩包口哨

A lot of backpacks have a hidden built-in whistle. The actual clip on many modern day backpacks that are meant for hiking or camping have that built-in whistle.

很多揹包都帶有一個隱藏的內置哨子。如今，不少遠足或露營專用的雙肩包的卡扣都有這種設計。

06 海嘯前兆

If you're ever at the beach and you see the water receding or far away from where it normally is, run. This normally means a tsunami is coming. And someone who paid attention in school in 2004 used this and saved their own life by getting out of there.

如果你在海灘上看到海水逐漸後退或遠離平常的位置，快跑!這通常意味着海嘯即將來臨。2004年，在學校認真聽講的人憑藉這個知識點逃脫，挽救了自己的生命。

07 水中方波

If you ever see square waves in the water, get out immediately. These waves have powerful currents under the water that can sweep you out and take you away.

如果你在水中看到方波，立刻離開。這些波浪下隱藏着強大的水流，可以把你捲走。

08 汽車進水

If your car ever goes into water, open a window or door immediately. If you don't do this, the pressure differential is too great and it will keep everything shut and you have to wait until your car is completely filled with water in order to get out.

如果你的車進水了，應該立即打開車窗或車門。如果不這樣做，巨大的壓差會將門窗都關死。到那時你只能等到車裏完全充滿了水才能逃出來。

09 電池不配套

If you're somewhere and you don't have the right size battery, you can use a smaller battery and put aluminum foil in that extra space and it will still work. The aluminum foil will transfer the electricity and get the job done.

如果你在某個地方，沒有合適尺寸的電池，可以使用更小號的電池，用鋁箔填充空餘的空間，這樣也行得通。鋁箔將傳輸電力並完成工作。
