这里是《每日语法》节目。我是爱丽丝·布莱恩特。
DO you like to travel?
你喜欢旅行吗？
Have you traveled a lot?
你经常旅行吗？
If so, you could say something like this:
如果是这样的话，你可以这样说：
I have been to a lot of places.
我去过很多地方。
Let's take a closer look at the statement to examine its grammar.
让我们仔细看一下这句话，以探讨其语法。
It uses a word form called a past participle.
它使用了一种叫做过去分词的单词形式。
Past participles have different functions in English.
过去分词在英语中有不同的功能。
"Been" is the past participle form of the verb "be".
“Been”是动词“be”的过去分词形式。
The speaker did not say, I have went to a lot of places.
说话者没有说，I have went to a lot of places。
That is because the word "went" is the past tense, not the past participle.
那是因为“went”是过去式，而不是过去分词。
Past participles have three main uses in English.
过去分词在英语中有三种主要用法。
One of them is to form perfect verb tenses.
其中之一就是构成完成时态。
A perfect verb tense is one that puts the word "has", "have" or "had" before its main verb.
完成时态是指把单词“has”、“have”或“had”放在主要动词之前的时态。
Take a look at the example again.
再来看看这个例子。
This is the present perfect tense, which is: have/has plus the past participle.
这是现在完成时，结构为：have/has+过去分词。
Knowing the name of this or other verb tenses is not important for today's lesson.
对于今天的课程，知道现在完成时或其他时态的名称并不重要。
The thing to remember is that all perfect tenses in English use some form of the verb "have" plus a past participle.
要记住的是，英语中所有的完成时态都使用动词“have”的某种形式加上过去分词。
