三年级英语作文insect篇四

大学英语精读3课后写作How did modern insect problem come to alarmingly threaten

1/ How did modern insect problem come to alarmingly threaten the very existence of humanity? (300)

The relationship between insects and human-beings is always seeking a delicate balance. Though it’s admitted that there’s a large amount of insects bring benefits to human, such as pollinator species, resource insects and even coprophagous that is addressed as cleaner insect, the number of pest insect is not within the scope that human could either tolerant or neglect. Pest insect acts as the notable enemy of forests, wood and fields, and also should be responsible for the widely spread disease. Recent years, with the rising temperature by globe warming, there’s a large possibility that insects would break up former habitat and turn to the journey for new activity spaces. In this way, the underlying threat caused by insects is lying in front of human-beings. The great harm that pests throw to human is presented specifically in two aspects, including insects themselves and the pesticide that aims to eliminate the pests, while which works to cause the opposite effect, making human themselves ultimate victims. First of all, pests are often introduced by human activities such as trade, travel or import. It comes to that the developed country have the ability to observe the invasive species while the developing country is under higher risk of preventing the pests and control the danger. Because of the delayed detection and insufficient technology, the modern insect problem evolve into critical trouble which greatly threat the existence of humanity.

Secondly, the abuse and misuse of pesticides also plays an important role. With the governmental permission or even encouragement, farmers sprayed the pesticides as much as they think it’s enough to kill the pests but without the consideration of environment, while ultimately causes the destruction of environment, water and air is contaminated and what’s worse, the crops and food would bring human body unimaginative harm.

In summary, on the surface, it’s the pest and unscientific use of pesticide that are to be blamed, while let’s get to the bottom of it, it’s human-being themselves to reap the fruits of their own action.（335）

三年级英语作文insect篇六

小学英语三年级知识点

( 一 )人称代词及数词

1．英语中表示人称的词叫人称代词。

人称代词有主格，宾格和所属格形式，人称代词有单数和复数

人称代词主格（作主语用）形式如下：I （我）you（你）he，she，it（他，她，它）we（我们）you（你们）they（他们，她们，它们）。注意：英语中你和你们一样都是YOU

人称代词用在及物动词或介词后面时要用宾格形式。

宾格形式“我”是“me”；（男）“他”是“him ”；（女）“她”是“her ”；“它”是“it ”；“我们”是“ us ”；“他们”是“ them ”

英语中人称代词表示所属关系，说明谁的×××，要用人称代词的所属格形式（也叫形容词性物主代词）其形式是：my(我的)；your(你的)；his，her，its(他的，她的，它的)；our(我们的)；your(你们的)；their(他们的)；如 my book ；your class；our school；his father；her mother；its tail；their teachers

2．英语中表示“是…”或“在…”要用动词BE ，BE动词有三种形式（am is are）不同人称要用be动词的不同形式。

用法如下：I am ；you are； he（ she it ）is； we are ；you are；they are

例：I am a girl. He is a boy. You are a teacher. It is a dog. We are pupils. You are doctors. They are elephants.

主格人称代词( I , you ,he ,she ,it, we , you, they) 可以和Be 动词的不同形式 (am, is, are )分别缩写为:

I’m = I am he’s = he is she ’s ==she is it’s = it is we’re = we are You’re =you are they’re =they are 但注意缩写式不可用于句尾。

3．英语中表示数量的词叫数词,数词有基数词(表示数目多少的词)和序数词(表示事物先后顺序的词),关于序数词以后会学到。

基数词如：one, two, three, four, five...

序数词如:first, second, third, fourth, fifth...

4. 英语中表示请求命令的句子叫祈使句。祈使句以动词原形开始

如：Stand up. Close your book. Open your mouth.

(二)冠词及疑问句

一、冠词：一般放在所说明的名词的最前面。冠词有两种形式。

1．a，an（一个），叫不定冠词（an用于其后跟着的词是以元音开头的词）。

如: a bird 一只鸟 a table 一张桌子 an orange 一个橘子 an insect 一只昆虫

2．the （这个，这些；那，那些）叫定冠词。

如：The sun is hot . The moon is in the sky.

a 表示“一个（指任何一个）”，而the表示有所指的某一个或某一些,而不是任何一个或任何一些。

Here is a picture of our classroom. In the picture there is a door.

The door is closed…

这是一张我们教室的图片,图片上有个门,门是关着的。句中的a 一（个）的意思，the picture 指的是前面提到的我们教室的那张图片，所以用the。the door 指的是图中的那个门，所以前面也用the。冠词用法还很多，也很复杂，随着学习的深入我们还会接触到许多其它用法。

二、疑问句: 疑问句是用来提出问题。

英语中有四种疑问句: 一般疑问句、特殊疑问句、选择疑问句和反意疑问句。

1. 一般疑问句: 英语中用“是”或“不是” ( yes或no ) 来回答的句子叫一般疑问句。 如：1. Is it a cat? Yes, it is. \ No, it isn’t

2.Are you Mary? Yes，I am. \ No, I am not.

3.Can you skate? Yes, I can \ No, I can’t.

4.Do you study English? Yes, I do\ No, I don’t

在含有BE（am ，is ，are）动词的句子中一般疑问句的构成是，将BE（am，is，are）动词置于句首并大写，后面接主语，再加其它成份，句末加问号即可。如上面例句1和2。

2．特殊疑问句:用疑问词来提问题的疑问句，叫特殊疑问句英语习惯叫作Wh-question。英语的疑问词一般放在句首。常见的疑问词有 what， who, which, when, where, why, how等。特殊疑问句不能简单用“是”或“不是”（yes或 no ）回答，要求回答具体内容。

如.1. What’s your name ? My name is Mary.

2. How old are you ? I’m nine.

3. What’s this ? It’s an apple.

4. What’s the shape ? It’s a circle.

一、选择正确的冠词

1) This is ___ cat . (A. a B. an C. the ){三年级英语作文insect}.

2) I want ___ ice-cream. (A. a B. an C. the )

3) ____ sun is yellow. (A. A B. An C. The )

4) I see ____ insect. (A. a B. an C. the )

5) That’s ____ pear. (A.a B. an C. the )

二、将下列句子改成一般疑问句

1）I’m Mrs Wang. ————————————.

2）You are Kitty Li. —————————————

3）He is my bother. __________________________

4) This is a cat. __________________________

5) It is in the box . _________________________

(三)祈使句

英语中有很多以一个动词大写开头的句子，通常表示一种命令或请求,(命令或请对方也就是听话者做什么)这样的句子就叫祈使句。祈使句也有否定式.是在动词前加否定词Don’t既命令或请对方不要做什么。你能想出更多例子吗？

Close the door, please . Open the window, please.

Wash your hands . Brush your teeth. Don’t Touch your nose.

读下面句子,找出祈使句。

1. Look at the table. What’s on it.

2. Is this your classroom?

3. Hello, Are you Mr Smith?

4. Don’t stand up. Sit down ,please.

5. Point to the picture.

6. I can write my name in English

7. Write down your name in English.

8. What can you write?
