今天我們要學習的短句是：

What's the occasion today?

I'm just curious as to why you didn't tell her the truth.

89: What's the occasion today? 今天是什麼大日子？

這是經常能用到的一句英文。回答比較簡單，可以用省略句來回答。

比如可以直接說：Peter's eightieth birthday! 前面的It is被省略了。

現在來學習一下句中的關鍵詞：

occasion: 特殊場合；重大活動；盛會

例如：

Sara's party was quite an occasion - there were over a hundred people there.

薩拉的聚會真是一次盛會——有一百多人參加。

關于occasion，有幾個常見搭配需要熟練掌握：

-on special occasions 在特殊的場合

-on the occasion of 值此...之際

-on occasion 有時；偶爾，間或

90: I'm just curious as to why you didn't tell her the truth. 我隻是好奇你為什麼不告訴她實情。

這是一句很棒的英文，其中有好幾個值得學習的要素。

-be curious about 對...好奇

例如：

Babies are curious about everything around them.

嬰兒對周圍的一切都很好奇。

-as to 關于，至于（相當于about，例句中用的是be curious as to其實就等同于be curious about）

例如：

He was uncertain as to which road to take.

他拿不準該走哪條路。

-tell her the truth 告訴她實情

這裡大家需要注意另外一個地道習語：

to tell (you) the truth 說句老實話，說實話

這裡的意思相當于：to be honest

例如：

To tell (you) the truth, I didn't understand a word of what he was saying.

說實話，他說的我一點兒也聽不懂。

總結一下：

-What's the occasion today? 今天是什麼大日子？

-be curious as to/about 對...好奇
