VOA一分鐘英語(yǔ)：如何使用感官動(dòng)詞 see 和 hear？

英語(yǔ)中的感官動(dòng)詞（verbs of perception）用來(lái)描述人的感官動(dòng)作。常用的感官動(dòng)詞有：see（看見(jiàn)）、hear（聽(tīng)見(jiàn)）、notice（注意到）和 watch（觀(guān)看）。
 
Hi, Saskia for BBC Learning English here. And today I'm going to tell you about how we use verbs of perception in English.
There are a number of these verbs, but I'm just going to look at two with you now: see and hear.
When we use these verbs, this is the form: first, the verb of perception; then, the object of the sentence; then, we have either the infinitive without to or the -ing form. Here's an example: 'I heard him go down the stairs' or 'I heard him going down the stairs'.
There's a slight difference between these two forms. When we use the infinitive, it suggests that we hear or see the whole action or event. Using the -ing form suggests that we hear or see something in progress.
'I saw her cross the street' means I saw her cross from one side to the other. 'I saw her crossing the street' means I saw her in the middle, on the way across.
