生活经验知识分享



She had difficulty keeping her eyes open (= because she was very tired) .
她连睁开眼睛的力气都没有了 。
He was breathing through his open mouth.
他张着嘴呼吸 。
此时形容词open反义词： closed
再看：
He was so sleepy that he could hardly keep his eyes __________.


A. open B. opening C. opened D. to open


此题应选A 。容易误选B 。主要是受 keep...doing 这一常用句式的影响 。


做好本题的关键是要分清：open 表示“开”这一意义时 ， 是形容词还是动词 。


1. open用作形容词时 ， 表示状态 ， 意为“开着的” 。如：


His eyes were wide open. 他的眼睛睁得大大的 。
She had left the door wide open .


她把房门敞开着 。

通道一年到头畅通无阻 。


The shop isn’t open today. 商店今天不开门 。
He was quite open about his reasons for leaving.
他对离开的原因完全未加隐瞒 。
He had always been open with her and she always felt she would know if he lied
他对她总是坦诚相待 ， 她也一直觉得如果他说谎 ， 自己一定能察觉 。

2. open用作动词时 ， 表示动作 ， 意为“开” 。如：

她张开双臂 ， 紧紧地拥抱了我 。
《柯林斯高阶英汉双解学习词典》

降落伞打不开怎么办？
The flowers are starting to open.
花开始绽放了 。


open用作动词 ， 是终止性动词 ， 通常不能用来表示“开”这一动作的持续 。如 。如：


这门打开已有一周了 。


正：The door has been open for a week.


误：The door has been opened for a week.


晚上让窗户开着 。


正：Keep the window open at night.


误：Keep the window opening at night.
keep sb(sth) doing sth.使某人或某物不定地做某事（动作之间稍有间隔）


通过以上分析 ， 我们可以清楚地知道：上面一题应用keep...open, 而不能用keep...opening, 其道理已很显然 。假若我们要用keep...opening, 那其实就是要使open 这一终止性动作不断地反复发生 ， 这显然是荒唐可笑的 。
