答案
1. Sibling bonds. 由第一段的第三句可知，兄弟姐妹的纽带有助于保持人们的大脑健康。
2. To find out whether having good relationships with siblings during childhood can have an effect on our health later in life. 由第二段的第一句可知，该研究的目的是搞清楚童年时期与兄弟姐妹的良好关系是否会对我们以后的健康产生影响。
3. Through telephone interviews. 由第三段中的“...researchers tested the cognitive abilities of some of the older adults through telephone interviews”可知，研究人员通过电话采访的形式来测试那些老年人的认知水平。
4. Staying lasting/close relationships with siblings during adulthood. 由最后一段的前两句以及because后的内容可知，童年与兄弟姐妹关系密切或不那么密切的人，成年后仍能与兄弟姐妹保持持久的关系，而那些在50、60和70多岁时与兄弟姐妹经常联系的人，在80多岁时认知健康状况更好。由此推出画线单词“this”指的是成年后仍能与兄弟姐妹保持亲密或持久的关系。
5. I will get along well with them, because it is good for our health. （答案不唯一，言之有理即可）
