日常语法:条件句

    In this week's episode of Everyday Grammar, we are going to talk about conditionals. We use conditionals to show that something is true only when something else is true. Conditionals offer endless possibilities for creative and imaginative expression.
    在本周的日常语法节目中,我们要来谈谈条件句。条件句用来表示只有某事发生,另一事才会发生的情况。条件句给创意和虚构提供了无限可能。

    Present real conditional
    现在真实条件句

    The present real conditional is the most basic kind of conditional. Basically, when A happens, B happens.
    现在真实条件句是条件句的最基本类型,表示当A发生时B发生。

    Here's an example of a present real conditional:
    以下是现在真实条件句的一个例子:

    "If it rains, I bring an umbrella."
    “如果下雨我就带上伞。”

    Conditionals have two parts: the if clause: "if it rains," and the result clause: "I bring an umbrella." You could also say "I bring an umbrella if it rains."
    条件句分为两个部分:if从句:“如果下雨,”以及结果从句:“我带上雨伞。”你也可以说“I bring an umbrella if it rains.”

    Poets and songwriters often use conditionals in their work. Listen for the present real conditional in this song by American songwriter Bob Dylan.
    诗人和作曲家经常在他们的作品中使用条件句。我们来听一下来自美国作曲家鲍勃·迪伦(Bob Dylan)的这首歌中的现在真实条件句。

    "If you see her, say hello
    “如果你看到她,请打声招呼

    She might be in Tangier"
    她可能在丹吉尔市”

    Notice that the verbs see and say are both in the present tense for the present real conditional.
    注意在现在真实条件句中,动词see和say都用的现在时。

    Present unreal conditional
    现在虚拟条件句

    The next conditional that we're going to talk about is the present unreal conditional. Use the present unreal conditional to talk about what you would do in an unreal, or imaginary situation. If A happened, B would happen. For example, "If I were you, I would take the job." The key word is would; it makes the conditional unreal. Would can only be used in the result clause of the sentence. Here's an example from American singer Johnny Cash.
    接下来我们我们要谈的是现在虚拟条件句。虚拟条件句用于谈论非真实或虚拟状态下你会做的事情。如果A发生,B就会发生。例如,“如果我是你,我就会接受这份工作。”关键字是would,它让该条件句变成虚拟状态。Would只能用于该句中的结果从句。以下是来自美国歌手约翰尼·卡什(Johnny Cash)的一个例子。

    "If I were a carpenter
    假如我是一个木匠

    And you were a lady
    而你是一位美女

    Would you marry me anyway?
    你还会嫁给我吗?

    Would you have my baby?"
    会给我生孩子吗?”

    To form a present unreal conditional, use a simple past verb in the if clause. In the result clause, use would followed by a simple present verb.
    现在虚拟条件句的if从句中请使用动词的一般过去时。而在结果从句中,使用would接动词的一般现在时。

    Use the verb were for all nouns in the if clause of the sentence. For example, "If she were an animal, she would be a cat." In informal speech, people might say, "If she was an animal, she would be a cat." But you should avoid this in formal writing.
    在该句的if从句中如果接名词就使用动词were。例如,"If she were an animal, she would be a cat."在非正式讲话中人们可能会说,"If she was an animal, she would be a cat."但在正式写作中要避免用was。

    Future real conditional
    将来真实条件句

    Now let's talk about the future real conditional. If A happens, B will happen. To make a future real conditional, use will in the result clause. For example, "If your plane is late, I will wait in the car." Use the future real conditional to talk about possible situations in the future.
    现在我们来谈谈将来真实条件句。如果A发生,B将会发生。将来真实条件句在结果从句中会用到will。例如,"If your plane is late, I will wait in the car." 我们使用将来真实条件句来谈论将来可能发生的状况。

    Speakers sometimes use the future real conditional to threaten others. Listen to actor Liam Neeson in the 2013 movie Taken. In this scene of the movie, Neeson's character is on the phone threatening the man who kidnapped his daughter.
    说话人有时会使用将来真实条件句来威胁别人。我们来听一下演员利亚姆·尼森在2013年拍摄的《劫持惊魂》中的台词。在这个电影场景中,尼森扮演的角色在电话中威胁绑架他女儿的男子。

    "If you let my daughter go now, that'll be the end of it. I will not look for you. I will not pursue you. But if you don't, I will look for you, I will find you, and I will kill you."
    “如果你现在放了我女儿,这事就算了。我不会来找你,我将不再追究。但是如果你不放,我就会来找你。我将会找到你然后杀了你。”

    This is only a quick introduction to conditionals. In a future episode of Everyday Grammar, we will talk about past and mixed conditionals. Until then, we will leave you with country music stars Johnny Cash and June Carter.
    以上只是条件句的简单介绍。在日常语法的下期节目中,我们将会讨论过去条件句和混合条件句。在此之前,我们先来听一下乡村音乐歌手约翰尼·卡什(Johnny Cash)和琼·卡特(June Carter)合唱的这首歌。

    "If I were a carpenter
    假如我是一个木匠

    And you were a lady
    而你是一位美女

    I'd marry you anyway
    我一定会娶你

    I'd have your baby
    和你生一个宝宝"
