Scientists Zap Clouds with Electricity

Summers in Taiwan can be very hot! When the sun comes out, everyone feels warm. And sometimes, it's too dry. Isn't there any way to make it rain?! 台灣的夏天很熱，有時候也很乾！有沒有甚麼方法可以讓天空下雨呢？ In the past, we could not change the weather. But scientists have had an idea. They have found a way to make it rain, using electricity. 現在，科學家發現一種用電讓天空下雨的方法。 We know where rain comes from. It falls from clouds in the sky. 我們知道雨水是從天上的雲落下來。 Clouds are made of water. When the water gets too heavy, the clouds start to rain. 雲是水構成的，當這些水太重，就會開始下雨。 Sometimes there is not enough rain. That is not good. When the rain is too little, people have no water to drink, and plants become too dry. So how can we make it rain more? 如果雨水太少，我們就會沒有水喝，植物也會乾枯。 Recently, scientists did a test. They used a little robot to zap a cloud with electricity. The electricity made the drops of water stick together. 科學家做了一個實驗，他們電擊一朵雲，讓雲層中的水滴黏在一起。 When the drops of water come together, they get heavier. Then they fall to earth. So when the cloud is zapped with electricity, it turns into rain. 水結成大水滴之後會變得更重，然後變成雨，落到地面。 What a useful idea. Scientists think it can help people. When the weather is too hot or dry, people can use this technology to make rain. All it takes is a cloud and a little electricity! ________________________________ Vocabulary 給雲層通上電，就有可能製造出雨水。 1. cloud 雲 How's the weather? 天氣怎麼樣？ A gray sky with lots of thick clouds. 灰色天空，有很多厚厚的雲。 Uh oh, that doesn't sound good. 糟糕，聽起來很不好。 No. I think it's going to rain very soon. 是不好，我想很快就會下雨。 2. rain 下雨 It rained all day yesterday. 昨天就下了一整天的雨。 But it's better than a hot and dry day. 但是總比又熱又乾好。 I prefer a dry day. 我比較喜歡乾燥的天氣。 3. electricity 電力 What's happening? 怎麼回事？ The light won't come on. 電燈不亮。 Because there's no electricity. 因為停電了。 4. in the past 從前 What should we do? 我們怎麼辦？ In the past we would light candles. 以前我們會點蠟燭。 No, I don't want to stay here. 不了，我不要待在這裡。 一起來讀讀單字吧。 cloud 雲 rain 下雨 electricity 電力 in the past 從前 ________________________________ Quiz 1.
