【分析】
首先通读对话理解语境，结合每个空的语法规则（时态、词性、单复数等）和词义，选择方框内单词的适当形式填空：
1. 第46空：根据问句"What are you doing right now?"判断为现在进行时，需用"be + 动词现在分词"结构，主语是I，对应be动词am，因此选择sit的适当形式；
2. 第47空：后文提到"Dark clouds"，且be动词为are，主语需用可数名词复数，cloud需变形；
3. 第48空：结合前文"don't go out"的语境，选择stay in表示"待在里面"；
4. 第49空：修饰动词shine需用副词，bright需变形为副词形式；
5. 第50空：固定表达"Lucky you!"意为"你真幸运！"，需用形容词lucky，注意首字母大写。
【解析】
1. 第46空：现在进行时结构为am/is/are + doing，主语I，故填am sitting；
2. 第47空：be动词为are，主语需用可数名词复数，cloud的复数形式为clouds，故填clouds；
3. 第48空：结合语境"不出去"，stay in表示"待在里面"，符合句意，故填stay in；
4. 第49空：修饰动词shine用副词，bright的副词形式为brightly，也可使用形容词bright修饰动词（两种形式均正确），故填bright(ly)；
5. 第50空：固定表达"Lucky you!"需用形容词lucky，首字母大写，故填Lucky。
【答案】
46. am sitting 47. clouds 48. stay in 49. bright(ly) 50. Lucky
