小明遇到这样两个问题：

根据以上数据，技术人员分别借助甲、乙两种不同的回归模型，得到了两个回归方程，方程甲： $\widehat{y}$ ^（1）= $\frac{4}{x}$ +1.1，方程乙： $\widehat{y}$ ^（2）= $\frac{6.4}{x^2}$ +1.6．

（Ⅰ）为了评价两种模型的拟合效果，完成以下任务．

（i）完成下表（计算结果精确到0.1）；

（ii）分别计算模型甲与模型乙的残差平方和Q₁和Q₂，并通过比较Q₁，Q₂的大小，判断哪个模型拟合效果更好．

（Ⅱ）该书上市之后，受到广大读者热烈欢迎，不久便全部售罄，于是印刷厂决定进行二次印刷．根据市场调查，新需求量为10千册，若印刷厂以每册5元的价格将书籍出售给订货商，试估计印刷厂二次印刷获得的利润．（按（Ⅰ）中拟合效果较好的模型计算印刷单册书的成本）

    Shyness (害羞) means feeling afraid when you're around other people. Some ____ (child) are born shy. Some become shy later because of ____(they) life  experiences. In  fact, everybody ____(get) a little shy sometimes.
