小学英语五年级下册各单元作文范例及点评

My weekend

There are two days on the weekend, Saturday and Sunday. On Saturday, I often go to my dancing class in the morning and do my homework in the afternoon, and I often help my mother do some housework. On Sunday, I always visit my grandparents in the morning and read books in the afternoon. After dinner, I often watch TV with my parents. We often have a good time.

【要领点评】

写法：这篇习作是按照时间顺序记叙周末的活动，记叙了周六和周日的上午和下午分别做了哪些活动及对活动的感受。即：周六上午：舞蹈课→下午：做作业和帮妈妈做清洁→周日上午：看望祖父母→下午：阅读→晚上：看电视，与父母交流→感受：高兴和愉快。我们还可以选取周六和周日中的几个比较主要的活动来写，先说明什么时间在什么地方由什么人做了什么事，有什么感受。再按照活动顺序把活动内容写清楚，最后抒发一下对这次活动或这个周末的感想。

时态：这篇短文我们可以用三种时态来写: a.一般过去时（主要描述你上个周末是怎样度过的）;b.一般现在时（主要描述你经常怎样度过周末）;c.一般将来时（主要描述你要怎样过周末）。这里我们来表述平时是如何过周末的，所以采用一般现在时来写。

注意：活动的相关表达方法可采用旧知识，eg.（例）起床get up，和新知识，eg. Climb mountains去爬山中的un很容易错写成nu。还要注意不要出现病句，eg. “I often watch TV with my parents.”不要写成 “I often with my parents watch TV .” 词量上控制在50 ~ 80 之间。

My Seasons

We have four seasons in a year. I can do many things in each season. In spring, the weather is cool and wind, I can fly kites when it’s wind. And I can go hiking with my family when it’s sunny and cool. Summer is hot. I often go swimming. I can eat ice-cream. I can also wear my beautiful dresses. In fall I can eat tasty fruits. I can watch the leaves fall. Winter comes, it’s often snowy in winter. We can play with snow and make a snowman, skate and ski. And summer is my favourite season, because I can swim. I love all the seasons.

【要领点评】{五年级英语作文范文}.

写法：这篇短文是描述“我的四季”，在写法上，是根据春、夏、秋、冬四季的更替来写的，先讲明每个季节的特征，之后再写在这个季节中的主要活动或比较有代表性的活动。同时讲一些自己的真实感受，最后阐述自己最喜欢的季节。在实际的写作的时候我们还可以先写出自己喜爱的季节及主要的活动内容，之后再去讲其他几个季节，还可以多讲解一下地域的季节特征和大自然中的其他景色，如：秋天的田地里一片金黄，农民在收割等等，这样写出来的四季更贴近实际。

时态：这篇习作讲的是“我的四季”，是比较惯常的一些行为，所以我们最好采用一般现在时和情态动词结合活动的写法。即：在什么季节，天气如何，我们可以做什么。

注意：在写作内容上，不可以像以往的内容那么简单，因为有四个季节，所以要写明季节，季节天气，季节性活动，活动的人，活动的感受等，要求句子顺序要正确，在写作中还要注意关联词的使用，如用了“因为”，就不能用“所以”，二者不可以同时出现。词量要控制在80个词以内。

My family

There are five people in my family. They are my grandma, grandpa, dad, mom and I. Look! Grandma is watching TV. Grandpa is reading a book. Dad is writing an e-mail. Mom is cooking dinner. I am doing my homework. I love my family!

【要领点评】

写法：这篇习作介绍了自己家的家庭成员，以及此刻他们正在干什么，表达了自己对家人的感情。

时态：由于本单元主要讲的是现在进行时态，所以建议采用现在进行时态。

句型：主语+be+动词的现在分词。

注意：本单元的重点是现在进行时态，注意在写句子时要保持时态的完整性，即系动词和动词的ing缺一不可。

In the park

It is sunny today .My mother, my father and I are going to the park. We like the park very much. It is very big and beautiful .There are many trees and flowers in it. Look! An old man is reading a book carefully on the chair. Two boys are jumping on the ground. Their mothers are talking. Two birds are flying in the sky. The ducks are swimming in the river. They are very happy. What is the cat doing? Oh, it is running after a mouse.

【要领点评】

写法：这篇习作是用现在进行时描绘出公园里的人和动物们正在进行的活动还运用了一般现在时叙述了公园美丽的景色。

时态：这篇文章可以采用一般现在时和现在进行时两种时态，由于本单元的语法项目是现在进行时，因此，描述的重点要放在现在进行时态上。

句型：一般现在时：主语+谓语+其他

现在进行时：（1）What +be (am,is ,are)+主语+v.-ing+其他?

（2）主语+be(am,is ,are)+ v.-ing+其他。

A Field Trip

【要领点评】

写法：这篇习作是按照郊游时的画面来描述的，记叙了同学们分别在郊游中做了哪些活动及郊游的感受。
