Duty of cricket Captain Essay or Paragraph in Hindi


क्रिकेट का कैप्टन टीम का लीडर होता है , उसे स्कीपर भी कहते हैं। . एक सामान्य खिलाड़ी की तुलना में उसका काम बहुत अधिक होता है। क्रिकेट टीम का कप्तान सबसे अनुभवी खिलाड़ी होता है। एक खिलाड़ी होने के अलावां उसे और भी कार्य करने पड़ते हैं। टीम के चुनाव में वह अपनी बात रखता है। खेल प्रारम्भ होने  के पहले वह टास करता है। वह बैटिंग क्रम को निर्धारित करता है। मैदान में खिलाडि़यों का स्थान बदलते रहता है। जीतने के लिए नई नई योजनाएं बनाता है। 
कप्तान यह भी निर्धारित करता है कि कौन सा गेंदबाज कौन सा ओवर बाल करेगा Iकप्तान की चतुराई और उसका निर्णय करने की क्षमता टीमको जीत दिलाने में बेहद कारगर होती है। टास जीतने के बाद गेंदबाजी  या  बल्लेबाजी का निर्णय कप्तान द्वारा लिया जाता है। कप्तान पिच की अवस्था  को ध्यान में रखते हुए निर्णय लेता है। यदि वह हारता है तो उसे काफी प्रश्नों का उत्तर देना पड़ता है। उसे पिच से  जुड़े फैसले का  तर्कसंगत उत्तर देना पड़ता है । 
उसे अच्छा वक्ता भी होना पड़ता है। उससे अंग्रेजी भाषा जाननी पड़ती है ताकि वह विदेशी कोच या अंपायर या खिलाडि़यों से सामंजस्य बना पाए।

Rule of Changing Singular to Plural -English Grammar

Rule of making plural is very easy. We simply add "s" to a noun to make it plural. This works for many words. But there are more words which ends differently at last and adding "s" to these words is not same. 
Rule Number 1: By adding "s"
e.g. 
SINGULAR
PLURAL
Girl
Girls
Tree
Trees
Rule Number 2:If noun ends with the letters sh, ch, ss or x then "es" is added to make it plural.
SINGULAR
PLURAL
Brush
Brushes
Match
Matches
Dress
Dresses
Box
Boxes
e.g.
Rule Number 3: Some nouns ends in "y" and before "y" there comes a consonant. In this case y is changed to i and es is added. Or it can be said that y is omitted and ies is added.
SINGULAR
PLURAL
Lady
Ladies
Baby
Babies
Puppy
Puppies
Pony
Ponies
 toy
toies 
There is no consonant just before y in 'toy' , therefore this rule will not be apply here. And hence correct plural of toy is toys and not toies.
Rule Number 4 :  Some noun ends in f. Then we simply replace f by ves. See the table.
SINGULAR
PLURAL
Leaf
leaves
Loaf
Loaves
Calf
calves
