根据下文回答下面问题:
1988年,一位爱好飞蛾的美国医生,发表了一篇科学论文,论述了夜晚的灯光是如何影响飞蛾的。这是一篇很普通的文章,但在当时,这也是一篇最明确地指出人造光会对动物产生危害的文章,一些针对人造光与动物关系的研究由此产生了。
在美国的佛罗里达海岸,城市的灯光曾造成刚破壳而出的小海龟迷路,使一些小海龟忽然爬向错误的方向,引导小海龟踏上了死亡之途。在很多场合下,即使动物们不直接暴露于灯光之下,它们也难以摆脱光污染的伤害,城区里的灯光会通过云层反射下来,使夜空处在非自然的光亮下,科学家们称这种情形为天空赤热。
最早指出天空赤热危害的是天文学家,因为这种光现象极大阻碍了他们对星空的观测。佛罗里达的科学家迈克尔·萨曼认为,钠灯也许可以成为城市的新光源。钠灯释放一种特殊的黄色波长,天文观测时,这种光波对观测的影响相对较小,而且对海龟和飞蛾之类的动物也不会造成伤害。萨曼说,海龟也许根本看不见钠灯,即使看见了,这种频率的光波也不会对它们的方向判断造成混乱。
然而,钠灯并不是万用良方。对于有些动物而言,钠灯的黄色光波和其他灯光的光波并无差异,有时甚至比传统的灯光显得更糟。突然暴露于灯光中的青蛙会延缓它们的进食和生殖行为,在黄光和红光下,火蜥蜴甚至无法从一个地方移动到另一个地方。灯光的照射使水生无脊椎动物在夜间的活动量减少,其后果就是减少了这些无脊椎动物对藻类的消耗,造成藻类的恶性繁殖,水质下降。灯光还可能对鸟类的磁场定位系统造成扰乱,使这些鸟儿时常迷失在电视塔的附近。灯光可以削弱飞蛾的防御反应,使飞蛾在遇到危险时失去逃跑能力。
______是那些有能力适应人造光的动物,它们在进化的过程中也不得不付出生物学的代价:某些异常的品质受到奖赏,______在正常的自然状态下,它们______变得不适应了。从逻辑上说,这样的进化选择将导致动物渐渐适应永恒的光照环境,并进化一些新的品质,它明显不同于在黑暗环境中生存的野生动物。假若让正常状态下和非正常状态下的这种动物交配繁衍,那将给这种动物带来灭绝的危险。
也许,我们的确到了找回那片失落星空的时候了。

根据文意,第5自然段中横杠上的连词,依次是:

A.虽然,至于,也

B.除非,或许,仍然

C.尽管,不过,反而

D.即使,而,却

Eat your vegetables. Wash your hands. Always say “please" and“thank you". We are full of advice for our children, but when it comes to money, we often have little to say. As a result, our children may grow up with clean hands and good manners, but without any idea how to manage their money.

Here are some basics that will help guide them their entire lives:

Show them the future. If your 13-year-old girl were to save$1,000,invest(投资)it at 8%and add$100 every month,by the time she's 65,she would have$980,983!

Be careful of credit(信用).Credit cards can help you buy necessary things and build a credit history,but they must be used responsibly, which means paying off your debt in time. Explain to your children that when you buy something using a credit card,you can easily end up paying two or three times what you would have paid if you used cash.

Teach patience. Suppose your child wants a new bicycle that costs $150. Rather than paying the cash,give him some regular pocket money and explain that by putting aside,say $15 each week,he will be able to buy it for himself in only ten weeks.

Provide incentive. Tell your children the importance of saving.“For every dollar he or she agrees to save and invest rather than spend, you agree to add another dollar to the pot,”says Cathy Pareto, expert in money planning.

Explain your values. Values and money are deeply intertwined, says Eilleen Gallo, co-author of The Financially Intelligent Parent. When your child demands that you buy something, explain why you really don’t want to buy it.“You might say,‘I'd rather save that money for your education,”,advises Gallo. Every time you spend or don't spend money,you have a chance to share your values.

64. The underlined word“incentive" in paragraph 6 means _____.

A. honor          B. praise         C. excitement      D. encouragement

65. What leads the writer to write this article?

A. Parents want to know how to educate their children.

B. He wants to share his good ideas about money matters.

C. He thinks money management the most important for children.

D. Parents care little about their children's management of money.

66. The writer gives some basics to help __________ in a proper way.

A. parents teach their children how to deal with money 

B. children follow their parents' instructions

C. children manage their money                   

D. parents save their money
