CBSE Class 9 Hindi (B) - कक्षा  ९ - हिंदी - संचयन - पाठ १ - गिल्लू


प्र१: सोनजुही में लगी पीली कली को देख लेखिका के मन में कौन से विचार उमड़ने?

उत्तर : गिल्लू  को सोन जूही की लता  सबसे अधिक प्रिय थी | जब उसकी मृत्यु हुई तो उसको उसी लता के नीचे समाधि दे दी गई |  सोन जूही में लगी पीली कली को देखकर लेखिका को लगा कि गिल्लू कली के रूप में प्रकट हो रहा है|


प्र २: पाठ के आधार पर कौवे को एक साथ समादरित और अनादरित प्राणी क्यों कहा जाता है?

उत्तर: हमारी संस्कृति में पूर्वजों को बहुत महत्व दिया गया है |  मान्यता है पितृ पक्ष में पुरखे ना गरुड़ के  रूप में आ सकते हैं, ना मयूर के, ना हंस के | हमसे कुछ पाने के लिए कौवे के रूप में आना पड़ता है|  श्राद्ध के दिनों में कौय को आदर दिया जाता है|  लोग इन दिनों सबसे पहले कौवे को भोजन देते हैं तब कौवा समादरित प्राणी है|  इसके विपरीत कौवे की काँव-काँव कर्कश स्वर में होती है तब वह अनादरित प्राणी माना जाता है|

Marie Curie was one of the most accomplished scientists in history. Together with her husband, Pierre, she discovered radium, an element widely used for treating cancer and studied uranium and other radioactive substances. Pierre and Marie’s amicable collaboration later helped to unlock the secrets of the atom.

Marie was born in 1867 in Warsaw, Poland, where her father was a professor of Physics. At an early age, she displayed a brilliant mind and blithe personality. Her great exuberance for learning prompted her to continue with her studies after high school. She became disgruntled, however, when she learned that the university in Warsaw was closed to women, Determined to receive a higher education, she defiantly left Poland and in 1891 entered the Sorbonne, a French university, where she earned her master’s degree and the doctorate in Physics.
