五年级英语语法知识点
在英语学习过程中，语音、词汇和语法是三个非常重要的要素。语法作为语言的一个构成要素，在英语学习中尤为重要。接下来学习啦小编为你整理了五年级英语语法知识点，一起来看看吧。
五年级英语语法知识点：现在完成时
构成：主语+助动词have, has+过去分词
用法：
1) 表示过去发生的和现在有某种联系的动作，常和just, usually, already, since等时间副词连用
I have just had lunch. (饱了，不用再吃了)
He has had a cup of tea.(不渴了，不用再喝)
They have already had their holiday. (不能再度假了)
The boy has already read the book. (已经知道书的内容了，不用再看了)
2) 询问别人是否做过某事一般用现在完成时：
Have you finished your homework?
Have you been to Beijing?
Have he seen the film?
3) 表示开始于过去并持续到现在的动作
I have lived in Beijing for twenty years.
I have worked for this school for 1 year.
4) 表示一种经历，经验：去过…地方，做过…事情，经历过…事情
I have never had a bath.
I have never seen a film.
I have never been to cinema.
I have ever been to Paris.
Have been to表示去过，have gone to 表示去了
I have been to London.(人已经回来)
He has gone to London.(人还在那里)
5) 表示一种结果， 一般不和时间副词联用
I have lost my pen.
I have hurt myself.
He has become a teacher.
She has broken my heart.
句型变化：
★变疑问句将助动词移到句首，变否定句在助动词后面加not.
e.g. Have you lost your pen? I have not lost my pen.
★肯定回答及否定回答
Yes, I have. No, I have not.
★特殊疑问句：
What have you done?
What has he done?
一般过去时与现在完成时的区别：
凡是有明确的表示过去的时间状语的句子为过去时
注意：有些动词表示的动作有一个终点，不能再延续，因此不能和表示一段时间状语连用
错：I’ve left Beijing for 3 days.
对：I left Beijing 3 days ago. I have been away from Beijing for 3 days.

五年级英语语法知识点：like的用法
like的搭配使用方法有两种：
like doing
like to do
一般情况，小学考试中出现的考题以“like doing”的搭配为主，一般而言“like doing”和“like to do”没有很大的区别，些微区别如下解释：
like doing 表示喜欢做某事，但是当下实行的可能性未知
like to do也表示喜欢做某事，当下去实行此事的可能性较大，隐藏着“想要做....”的含义
我们在出题中，经常喜欢考一下like to do这样的句型，来考查学生是否掌握该固定句型：
eg：Would you like _______________ (take) part in the meeting?
此题的答案： to take 而不是 taking
Would you like to do的固定句型，是典型的征询他人意见的句型，表示“做....好吗?”
肯定回答该句： Yes, I would.
否定回答该句： No， I wouldn't.
练一练：
1. We don’t like _____(eat) hamburgers.
2. I'd like ________(finish) my homework today.
3. They like ________(talk) with each other.
4. Would you like _______(have) some apple juice?
5. Both of them like ________ (swim)tomorrow.
