Gia lives on the second floor. Her bedroom window faces a big tree.
吉娅住在二楼。她卧室的窗户正对着一棵大树。
Every morning at six o'clock, something goes tap, tap, tap. The sound is loud. Gia wakes up. She is tired and she is cross.
每天早上六点，都有什么东西发出“嗒、嗒、嗒”的声音。声音很响。吉娅醒了。她又累又恼火。
"Who is there?" she says. Nobody answers. She opens the curtain. She looks at the tree. It is empty.
“谁在那儿？”她说。没人回答。她拉开窗帘，看着那棵树。树上什么也没有。
The next morning, the sound comes again. Tap, tap, tap. It is six o'clock. Gia jumps out of bed. She looks left and right. She sees nothing.
第二天早上，声音又来了。嗒、嗒、嗒。是六点钟。吉娅从床上跳起来，左看右看，什么也没看到。
She tries to sleep again. She puts a pillow on her head. It does not help. The tapping is too loud. She goes to work with sleepy eyes.
她想再睡一会儿，把枕头压在头上也没用。敲击声太响了。她睡眼惺忪地去上班了。
At the office she tells her friend. Her friend says, "Maybe a ghost lives in your tree." Gia does not laugh. She wants to know the answer.
在办公室，她把这件事告诉了朋友。朋友说：“也许你的树上住着一个鬼。”吉娅没有笑。她想知道答案。
"Maybe it is the wind," she thinks. But the leaves do not move. The air is still.
“也许是风，”她想。可是树叶没有动，空气一动不动。
At lunch she calls her brother. "Something taps on my window every morning," she says.
午饭时，她给哥哥打了电话。“每天早上都有东西敲我的窗户。”她说。
"Is it a ghost?" he asks.
“是鬼吗？”他问。
"I do not think so," says Gia.
“我觉得不是。”吉娅说。
"Is it a branch?"
“是树枝吗？”
"No. The branches are far from the glass."
“不是。树枝离玻璃很远。”
"Then make a video," says her brother. "Use your phone."
“那你拍个视频吧，”哥哥说，“用你的手机。”
That night Gia puts her phone on the shelf. The camera looks at the window. She starts the video. Then she goes to sleep.
那天晚上，吉娅把手机放在架子上，让镜头对着窗户。她开始录像，然后去睡觉了。
At six o'clock, tap, tap, tap. Gia does not open her eyes. She is too sleepy. She wants to sleep a little more.
六点钟，嗒、嗒、嗒。吉娅没有睁眼。她太困了，想再多睡一会儿。
At breakfast she watches the video. At first she sees only the grey window. Then a small bird lands on the tree. It has a red chest and a black head. It looks at the glass.
吃早饭时，她看那段视频。起先只能看到灰蒙蒙的窗户。然后一只小鸟落在树上。它的胸脯是红色的，脑袋是黑色的。它看着玻璃。
Then the bird flies at the window. Tap! It hits the glass with its beak. It flies back to the tree. Then it comes again. Tap! Tap! Tap!
接着小鸟朝窗户飞去。嗒！它用喙撞在玻璃上，又飞回树上。然后它又来了。嗒！嗒！嗒！
"A bird!" says Gia. She laughs. "You are my ghost!"
“是只鸟！”吉娅说。她笑了。“原来你就是我的鬼！”
But why does the bird do this? She looks on her phone. She reads a short page.
可是小鸟为什么要这样做呢？她在手机上查了查，读了一篇短文。
The page says, "Glass can look like a mirror. The bird sees another bird. It thinks the other bird is an enemy. So it fights."
文章里写道：“玻璃有时像镜子。小鸟看到了另一只鸟，以为那是敌人，所以就打了起来。”
"It fights itself," says Gia. "Poor little bird."
“它在跟自己打架，”吉娅说，“可怜的小鸟。”
She wants to help. She takes a big sheet of white paper. She cuts it into long pieces. She opens the window. She sticks the paper on the outside of the glass. Now the window does not look like a mirror.
她想帮帮它。她拿来一大张白纸，剪成长条，打开窗户，把纸条贴在玻璃的外面。现在窗户看起来不像镜子了。
That night she goes to bed early. She wakes up at six o'clock. It is quiet. There is no tap. She smiles and turns over.
那天晚上她早早上了床。六点钟醒来时，四周很安静，没有敲击声。她笑了笑，翻了个身。
At seven o'clock she opens the window. The bird sits on the tree. It looks at the paper. Then it looks at her. It does not fly at the glass.
七点钟，她打开窗户。小鸟停在树上。它看看纸条，又看看她，没有朝玻璃飞去。
"Hello," says Gia. "I am sorry about your enemy."
“你好，”吉娅说，“对不起，让你多了个敌人。”
She finds a small bowl in the kitchen. She puts some seeds in it. She hangs the bowl on the tree.
她在厨房里找到一个小碗，放了一些种子，把碗挂在树上。
The bird jumps down and eats. Gia sits at the window with her tea.
小鸟跳下来吃了起来。吉娅端着茶坐在窗边。
"Good morning, little fighter," she says.
“早上好，小斗士。”她说。
