Bush, George Washington, and Lyndon Baines Johnson are all first-borns．
When a second child arrives, parents are more relaxed． The second child is allowed to be more independent． But he also has to compete with the first-born for the parents’ attention and love． These children often choose different sports and hobbies to show independence．【小题4】 They are often adventurous, fun-loving, and outgoing, but can be jealous and get angry easily．
The youngest child tends to be the happiest． He has fewer responsibilities and more freedom． These children do not feel pressure to do well at school and work, but have to be creative to get their family’s attention．【小题5】 So, many famous talk-show hosts and comedians were born last．

C．But you have different personalities．
D．Their parents may probably love them more．

C

(答案→)C 解析：这篇短文主要介绍了为什么兄弟姐妹们共同生活在同一个房子里又有相同的父母但是会有不同的性格的原因。【小题1】根据上句内容，你们共同生活在同一个房子里又有相同的父母。后面问为什么，可知两句之间有转折故选，故选C。【小题2】根据后句As a result, first-borns are often responsible, hard-working and serious结果,老大通常是负责,勤劳认真的．故选F。【小题3】根据后面的句子For example, George W. Bush, George Washington, and Lyndon Baines Johnson are all first-borns描述许多总统都是老大（先出生的孩子）故选A。【小题4】根据上句这些孩子常常选择不同的体育运动和爱好以显示他们的独立和后句他们往往是冒险的,风趣的,外向的,但是很容易吃醋和生气的的联系，后句就是展示他们的性格，故选E【小题5】根据后句的描述许多著名脱口秀主持人和喜剧演员是最后出生的（老小）可知他们的性格，故选B。
