Today is my 12th birthday. My parents give me a box of small eggs as a gift. They look small and white.
23rd March
The eggs become small caterpillars. They eat green leaves. They grow day by day.
20th April
The caterpillars are big and fat. But they don’t eat the leaves now. They start to make small houses. Dad tells me these white houses are
cocoons.
8th May
There is a small hole in one cocoon. A butterfly comes out. It looks so beautiful. Look! It can fly. What a wonderful gift!

解析:
1. 第1题:通读所有日记内容,文章依次记录了卵孵化成小毛毛虫、毛毛虫长大结茧、最终破茧成为蝴蝶的全过程,这是蝴蝶的完整生命周期,A选项仅描述卵的一生太片面,C选项是叶子的生命周期不符合内容,因此选B。
2. 第2题:第一篇日记的下一篇标注的日期是3月23日,说明第一篇日记的日期一定早于3月23日,三个选项里只有A选项3月8日符合时间逻辑,B选项4月15日、C选项6月12日都晚于3月23日,不符合,因此选A。
3. 第3题:根据3月23日的日记内容"The eggs become small caterpillars. They eat green leaves.",可知小毛毛虫吃绿叶,对应选项A,因此选A。
4. 第4题:根据4月20日的日记内容,毛毛虫长大后不再吃叶子,开始给自己做白色的小房子,这个阶段的结构就是茧,因此cocoons的中文意思是茧,选C。
5. 第5题:根据5月8日的日记内容"A butterfly comes out. It looks so beautiful. Look! It can fly.",可知这天礼物变成了蝴蝶,对应插图C的蝴蝶形象,A是茧、B是毛毛虫都不符合,因此选C。
