Today we’re going to do three simple experiments that have to do with surface tension and water. You might be surprised at some of the results!
What you will need:

今天我們要做三個簡單的實驗,這些實驗和表面張力及水有關,部分實驗結果可能會讓你感到意外喔!
所需材料︰
一個杯子
水
銅板
迴紋針
廚房紙巾或面紙
洗碗精
鋁箔紙
水槽
水槽塞子
EXPERIMENT ONE 實驗一
► Fill the cup to the very top with water. The water should be flat and look like it’s about to overflow.
► Guess how many coins you can add before the water overflows.
► Now start adding coins one by one. Drop the coins in carefully. You don’t want to disturb the water too much.
► How many coins did you add? Was your guess close? How does the surface of the water look?
►在杯中裝入滿滿的水,杯口的水面應該平平的,並且看起來像要滿出來的樣子。
►猜猜看你可以投入多少枚銅板而不讓水溢出來。
►開始把銅板一枚一枚放入杯中;小心地把銅板放進去,不要過於攪動水面。
►結果你放進多少枚銅板?結果你猜得準嗎?杯口的水面看起來如何?
EXPERIMENT TWO 實驗二
► Fill a cup about three-quarters full with water. Drop in a paperclip. What happens?
► Now tear off a small piece of the paper towel. Put a paper clip on top of it and carefully place it on the water surface.
► Wait for the paper towel to be saturated with water. It should sink to the bottom. If it doesn’t, give it a slight nudge with the tip of a pencil or some other pointy object. Be careful not to disturb the paperclip.
► The paperclip should float on the surface.
► Add a drop or two of soap to the water. Don’t hit the paperclip. What happens?
►在杯中倒入四分之三滿的水,並投入一根迴紋針,會發生什麼事?
►撕下一小塊廚房紙巾,再把一根迴紋針放在紙巾上,然後小心地將其舖放在水面上。
►等紙巾被水浸濕後應該會沉到杯底;如果沒有沉下去,可以用鉛筆筆尖或其他尖頭的東西輕推一下,但小心不要動到迴紋針。
►迴紋針應該會浮在水面上。
►在水裡加入一兩滴洗碗精,但不要碰到迴紋針。會發生什麼變化?
EXPERIMENT THREE 實驗三
► Fill the sink about halfway full of water. Make sure there’s no soap in the sink.
► Make a small boat using the aluminum foil. Place the boat in the water. Wait for it to stop moving.
► Drop a few drops of water behind the boat. What happens?
► Now try dropping a few drops of soap behind the boat. What happens?
►在水槽裡裝入約半滿的水。確認水槽裡沒有清潔劑。
►用鋁箔紙做一艘小船,把鋁箔小船放到水中,並等它靜止不動。
►在小船後面滴幾滴水,會發生什麼事?
►試著在小船後面滴幾滴洗碗精,會有什麼變化?
A: Hey, didn’t you go to the opening of the Mitsui Shopping Park LaLaport Nangang last week? B: Yeah, there are about 300 shops, including the first overseas branch of Japan’s Mahou Dokoro — a famous Harry Potter-themed store. A: Wow, I’ve always wanted to get a magic wand. B: There are also a bunch of great restaurants, such as Smart Fish hotpot restaurant. A: I wish I had Harry Potter’s “apparition” and “disapparition” magic, so I could teleport to the mall right now. A: 你上週不是有去LaLaport南港的盛大開幕嗎?有什麼特別的? B: 那裡有多達300家專櫃,包括魔法之地的海外首店——它可是日本知名的《哈利波特》專賣店。 A: 哇我一直想買根魔杖。 B: 另外還有各式各樣的美食,像是林聰明沙鍋魚頭。 A: 真希望我也有哈利波特的「現影術/消影術」魔法,能瞬間移動到商場去! (By Eddy Chang, Taipei Times/台北時報張迪)

Dos & Don’ts — 想想看,這句話英語該怎麼說? 1. 你覺得這部電影怎樣? ˇ What do you think of the movie? χ How do you like the movie? χ How do you think of the movie? 註︰What do you think of = What is your opinion of。 think 的受詞是 what,不能用 how。 2. 你認為哪一個歌星唱得最好? ˇ Which singer do you think is the best? χ Do you think which singer is the best? 註︰英語中 which singer 似乎是 do you think 的受詞,實則 do you think 是插入語,其他例子如下: 你以為他喜歡誰?
