探究why的奥秘

王小英

精彩亮相：大家好，我来自疑问副词家族。我的意思是“为什么”。要问我有什么本领？我的本领可大了，今天就给大家讲一讲：

1. 我的意思是“为什么”，是个疑问副词，我能作为疑问词引导特殊疑问句，用来询问原因，针对此类问句进行回答时，一般要用because引导。eg:

——Why does he go to the hospital? 他为什么去医院？

——Because his father works in it. 因为他爸爸在那里工作。

——Why do you like milk? 你为什么喜欢牛奶？

——Because its healthy food. 因为它是健康食物。

——Why does she like English? 她为什么喜欢英语？

——Because it is interesting. 因为它很有趣。

——Why do you arrive late? 你为什么迟到了？

——Because I cant find this place. 因为我找不到这个地方。

揭示秘诀：在含有实义动词的一般现在时的句子中，why后面的助动词用do还是does，关键要看主语：如果主语是第三人称单数，就一定要用does，否则，用do。但无论用do还是does，其谓语动词都必须用原形。eg:

——Why does your sister go to the zoo? 你妹妹为什么去动物园？

——Because she likes animals. 因为她喜欢动物。

2. 我还可以向别人提出建议，句型为“Why dont you+动词原形…？”或“Why not+动词原形…”意为“为什么不……呢？”。eg:

Why dont you/Why not go for a walk? 为什么不去散步呢？

【小试牛刀】

一、对划线部分提问。

1. I like monkeys because they are cute and smart.

____ ____ you like monkeys?

2. She likes pandas because they only live in China.

____ ____ she ____ pandas?

3. I feel sorry for the animals in the zoo because they are in the cages.

____ ____ you feel sorry for the animals in the zoo?

二、在下列各对话空白处填上适当的单词，使对话内容完整通顺。

1. A: ____ are you late for school?

B: ____ I dont catch the early bus.

2. A: Why do you like koalas? They are so shy.

B: ____ they are interesting and they live ____ the tree.

3. A: ____ are the tigers not happy in the zoo?
