प्रदूषण  

 

 प्रदूषण एक गंभीर पर्यावरणीय समस्या है। यह  पृथ्वी पर जीवन को प्रभावित कर रहा है।
 प्रदूषण मुख्यतः 4  प्रकार का होता है  वायु प्रदूषण, जल प्रदूषण, भू प्रदूषण और ध्वनि प्रदूषण। 
वाहनो के बढ़ती संख्या की वजह से  हानिकारक और ज़हरीली गैसों का स्तर निरंतर बढ़ता जा रहा है  वही दूसरी और कारखाने और खुले में आग जलाना, वायु प्रदुषण के मुख्य कारण हैं। कारखानें भी  निर्माण प्रक्रिया के दौरान  कुछ विषाक्त गैसें, गर्मी और ऊर्जा रिलीज  करते  है वायु प्रदूषण इंसान और जानवरों में फेफड़ों के कैंसर सहित अन्य सांस की बीमारियां उत्पन्न कर रहीं हैं| 

कारखानों, उद्योगो, सीवेज सिस्टम और खेतों आदि के हानिकारक कचरे का सीधे तौर पे नदियों, झीलों और महासागरों के पानी के मुख्य स्रोत में मिलाना  जल प्रदुषण का मुख्य कारण है। 

उर्वरक, कवकनाशी, शाकनाशी, कीटनाशकों और अन्य कार्बनिक यौगिकों के उपयोग के कारण भू  प्रदूषण होता है। 
भारी मशीनरी, वाहन, रेडियो, टीवी, स्पीकर आदि द्वारा उत्पन्न ध्वनि, ध्वनि प्रदूषण के कारण है जो की सुनने की समस्याओ और कभी कभी बहरापन का कारण बनती हैं।
 प्रदूषण पर नियंत्रण पाने के लिए संयुक्त प्रयास की आवश्यकता है जिससे की हम एक स्वस्थ्य और प्रदुषण मुक्त वातावरण पा सके।

Past tense

Past tense

 
The main rule is that for every verb in English, there is only one form of it in the past tense.
(The exception is the Past tense of To Be, which has two forms: was and were)
For example: The past tense of the verb want is wanted.
Wanted is used as the past tense for all subjects/pronouns.

I wanted
You wanted
He wanted
She wanted
It wanted
We wanted
They wanted
So you just have to learn one word to be able to use it in the past tense. In this case we just needed to learn the one word wanted which can be used for all subjects (or people).
Past Tense Regular Verbs
To change a regular verb into its past tense form, we normally add –ED to the end of the verb.

play – played
cook – cooked
rain – rained
wait – waited
There are some exceptions with a slight change in spelling which you can see here:
Past Tense
Any event or action that took place in the past can be referred to as the past tense. Below we have discussed in detail the four sub parts of past tense in English grammar. 

Simple Past 
Simple Past Tense
Rule: Subject + V2 + Object
For example: He ran away
Here, the subject is “He” and “ran” is the second form of verb (V2) of “run” followed by the object

Past Continuous 
Past Continuous Tense
Singular Plural
Rule: Subject + was + V1 + ing + Object Rule: Subject + were + V1 + ing + Object
For example: She was going shopping
Here, the subject is “She” + was

It is followed by the first form of verb (V1) “go” + “ing” and then the object “shopping”

For example: They were going shopping
Here, the subject is “They” + were

Followed by the first form of verb (V1) “go” + “ing” and then the object “shopping”

Past Perfect 
Past Perfect Tense
Rule: Subject + had + V3 + Object
For example: Sumit had left the job
Here the subject is “Sumit” + had

Then “left”, which is the third form of verb (V3) “leave” is given followed by the object

Past Perfect Continuous 
Past Perfect Continuous Tense
Rule: Subject + had been + V1 + ing + Object
For example: They had been preparing for their performance for two months
Here the subject  is “They” + had been

It is followed by “preparing”, which is the first form of verb (V1) of “prepare” and then the object

To help you understand past tense and its form even better, given below are a few examples to simply the concept:

I played football yesterday (Simple Past)
I was playing football yesterday (Past Continuous for Singular)
They were playing football yesterday (Past Continuous for Plural)
They had played football yesterday (Past Perfect)
They had been playing football the entire yesterday (Past Perfect Continuous)
