单项选择题

根据以下资料回答第21~36题:
家住沈阳的赵力先生与爱人李珍同岁,现年38岁,已有一个10岁的女儿和一个7岁的儿子。赵力为个体工商户,一直靠收购废旧钢材为生。赵力自幼顽皮、厌学,只读了两年书,现在每天靠助手读报和看电视获取信息,但天资聪颖,善交际,生意一直不错。他深觉知识不够,扩大经营力不从心。目前赵力每年税后收入20万元。李珍为国有事业单位员工,税后月薪4000元,缴五险一金。
目前,家庭每年生活费支出48000元,学费支出16000元,儿女才艺支出10000元,旅游费用支出20000元,交际费用支出30000元。
现有住宅一套,价值100万元,贷款7成,20年期,利率6%,按月本利平均摊还,已还5年。20万元的轿车一辆。有活期存款2万元,以备急用。定期存款30万元,债券基金50万元,拟给子女留学使用。目前两人都无商业保险。
“你不理财,财不理你”的观念深入人心。但赵力认为,只要努力工作赚到钱,什么问题都会迎刃而解。近年来,面对通货膨胀,他感到自己的钱缩水了,担心攒下的钱不够子女留学。而面对火爆的资本市场,又苦于自己不会打理。于是,赵力慕名找到某银行财富管理中心高级客户经理——国际金融理财师江心扬。
几番接触后,他将自己的家庭情况及想法告知了江心扬,请江心扬给自己的家庭做财务规划,并将80万元资产交给江心扬全权打理。希望儿女能接受良好的教育,别像自己一样没文化:60岁退休后生活无忧,能周游世界。

     Toucans(巨嘴鸟), a kind of tropical birds known for its colorful beak, are very smart. In Mexico, my

dad became friends with a toucan that was in a "walk in and see the birds" cage. The toucan was so smart that it knew how to get out. It just needed some human to help it. It almost flew out while we were leaving!

I also noticed that all toucans have different beaks! They also have very long unique beaks with an extremely long tongue. It struts(大摇大摆地走) around with its chest sticking out and beak pointed forward. The

toucan is a beautiful bird! The beak has a red tip (different shades on every one), but sometimes there is a

little turquoise on the bottom half. Then, right where the beak separates there is a splotch of yellow. And

the rest of the beak is green. The toucan takes very much pride of itself.

     The toucan eats fruit and seeds. The ramphastidae(the toucan family) is known for its long beak, and

37 species. Toucans also feed on insects, small lizards, bird nestlings and eggs. They nest in hollow trees

where they incubate and care for their young.They are found in the woody areas.

     Of the various toucan facts, here is an odd one. Citizens of Central and South America associate the

toucans with evil spirits. They think the birds can be the personification of evils. Where couvades(父代母育) is practiced, the father of a new child must not eat toucan flesh as it is believed to bewitch the

new-born child. Yet the toucan can also be a tribal totem(图腾). So the medicine men use it as a symbol

to fly to the spirit world.
