Lesson 89 Television Day: Swindle's Ghost
    第89課 電視日:斯威特爾鬼魂
    Some people believe that there are houses which are haunted by ghosts.
    有人相信有鬧鬼的房子.
    Perhaps there are,perhaps there aren't--it's hard to say.
    或許有,或許沒有--很難說.
    Today we are going to describe a scientific experiment
    今天我們要描述一個科學實驗,
    during which a "ghost"was seen.
    實驗過程中見到了"鬼".
    The "ghost" is really an after-image.
    此"鬼"實際上是個余像.
    It is called "Swindle's Ghost"
    它之所以被稱為"斯威特爾鬼魂",
    because the experiment was first performed by an American psychologist called Swindle.
    那是因為首次實驗是由一位名叫斯威特爾的美國心理學家做的.
    This is how our own experiment was performed.
    下面是我們自己的實驗過程:
    A dark,moonless night was chosen and the curtains were drawn
    選擇一個黑暗無月光的夜晚,拉上窗簾,
    so that no light could enter from outside.
    使外邊光照不進來.
    Half a dozen people were asked to sit round a table in the middle of the room.
    請6個人坐在房間中間的桌旁.
    A table-lamp was placed in the centre of the table.
    桌子的中央放一盞臺燈.
    When everyone was seated,the lamp was turned off for ten minutes.
    待每人就座后,熄燈10分鐘.
    Everyone sat in complete darkness and looked towards the lamp
    大家坐在一片漆黑中朝著燈看,
    till they got quite used to the darkness.
    直到完全習慣于黑暗.
    They sat perfectly still and kept looking in exactly the same direction.
    大家一動不動地坐著,一直朝同一方向看.
    Then the lamp was turned on for exactly one second and then off again.
    然后開燈1秒鐘,再關燈.
    Shortly afterwards,the whole scene became visible in the darkness.
    不一會整個景象即可在黑暗中見到.
    It was a very clear "ghost" image which lasted for a few seconds.
    這是一個非常清晰的"鬼"影,能持續(xù)數(shù)秒鐘.
