想要深入学习英文，语法是不可躲的一知识点。下面是小编给大家整理的英文语法，供大家参阅!

英文语法：短语动词

动词加小品构成的起动词作用的短语叫短语动词(Phrasal Verb)。例如：

Turn off the radio. 把收音机关上。(turn off是短语动词)

短语动词的构成基本有下列几种：

1) 动词+副词，如：black out;

2) 动词+介词，如：look into;

3) 动词+副词+介词，如：look forward to。构成短语动词的副词和介词都统称为小品词(Particle)。

英文语法：Going to

Going to is not a tense. It is a special expression to talk about the future.

Structure of Going to

The structure is:

subject + be + going + infinitive

The verb be is conjugated (past, present or future).

Use of Going to

Going to - intention

We use going to when we have the intention to do something before we speak. We have already made a decision before speaking. Look at these examples:

1. Jo has won the lottery. He says he's going to buy a Porsche.

2. We're not going to paint our bedroom tomorrow.

3. When are you going to go on holiday?

In these examples, we had an intention or plan before speaking. The decision was made before speaking.

Going to - prediction

We often use going to to make a prediction about the future. Our prediction is based on present evidence. We are saying what we think will happen. Here are some examples:

1. The sky is very black. It's going to snow.

2. It's 8.30! You're going to miss the train!

3. I crashed the company car. My boss isn't going to be very happy!

In these examples, the present situation (black sky, the time, damaged car) gives us a good idea of what is going to happen.
