英语语法一般现在时详解（英语基础语法之）

我们今天一起学习英语基础语法中的：现在进行时(also called Present Progressive)

我们经常在英语中使用现在进行时，在结构和用法上与一般现在时非常的不同

We often use the Present Continuous tense in English. It is very different from the Present Simple tense, both in structure and in use.

那我们应该怎样使用现在进行时呢？

现在进行时的结构是

助动词（ be ）在一般现在时中是变位的：am ， are ， is

助动词（be)在一般现在时中是会变化的：am, is, are （翻译得不是很好，以下是原文）

The auxiliary verb (be) is conjugated in the Present Simple: am, are, is.

主动词在现在分词形式中是不变的：- ing

The main verb is invariable in present participle form: -ing.

在否定句中，我们插入not在助动词和系动词之间

For negative sentences we insert not between the auxiliary verb and the main verb.

在疑问句中我们将主语和be动词对调

For question sentences, we exchange the subject and the auxiliary verb.

看一下这些现在进行时的例句：

我们如何使用现在进行时？

使用现在进行时：

1 现在正在发生的事（action happening now ）

说话前已经发生，说话后还会持续

2将来会发生的事（action in the future）

在说话前已经计划好的未来发生的事（搭配暗示未来的词汇使用：明天，明年，今年12月等）

01 现在进行时表示现在发生的动作

（Present Continuous for action happening now）

a) for action happening exactly now

看这些图，Right now you are looking at this screen and at the same time...

b) for action happening around now

行为不一定是现在发生的，但这是刚刚发生过和即将发生的，不代表定理和习惯。

The action may not be happening exactly now, but it is happening just before and just after now, and it is not permanent or habitual....

请看这些栗子：

Muriel is learning to drive.

I am living with my sister until I find an apartment.

02现在进行时表示将来

（Present Continuous for the future）

我们也可以用现在进行时来谈论将来——如果我们加一个将来的词！！我们必须加上（或从上下文理解）一个未来的词。“未来词”包括tomorrow, next year, in June, at Christmas等。当我们在说话之前已经计划好要做什么的时候，我们只用现在进行时来谈论未来。我们在发言之前已经做了决定和计划。

We can also use the Present Continuous tense to talk about the future - if we add a future word!!

We must add (or understand from the context) a future word. "Future words" include, for example, tomorrow, next year, in June, at Christmas etc.

We only use the Present Continuous tense to talk about the future when we have planned to do something before we speak.

We have already made a decision and a plan before speaking.

现在进行时表示将来（条件）

1、有表示将来的时间词：next month、tomorrow

2、说话前已经做好打算。

看下面这些栗子：

We're eating at Joe's Cafe tonight. We've already booked the table..

They can play tennis with you tomorrow. They're not working.

When are you starting your new job?

在这些例子中，在说话之前都有一个确定的计划或方案。这些决定和计划是在说话之前作出的。

In these examples, a firm plan or programme exists before speaking.The decision and plan were made before speaking.

我们怎么拼写现在进行时呢？

现在进行时形式：

1.普通➕ing

2.倒数第二个单词重读元音，双写最后一个单词➕ing

例:stop

3.ie结尾，变ie为y➕ing

例：lie

4.元音➕辅音➕e，去e➕ing

例:come
