根据短文理解,选择正确答案。
Watching some children trying to catch butterflies one hot August afternoon, I was reminded of an incident in my own childhood.When I was a boy of 12 in South Carolina, something happened to me that cured me forever of wanting to put any wild creature in a cage.
We lived on the edge of a wood, and every evening at dusk the mockingbirds would come and rest in the trees and sing. There isn't a musical instrument made by man that can produce a more beautiful sound than the song of the mockingbird.
I decided that I would catch a young bird and keep it in a cage and in that way would have my own private musician.
I finally succeeded in catching one and put it in a cage. At first, in its fright at being captured, the bird fluttered about the cage, but eventually it settled down in its new home. I felt very pleased with myself and looked forward to some beautiful singing from my tiny musician.
I had left the cage out on our back porch, and on the second day of the bird's captivity my new pet's mother flew to the cage with food in her mouth. The baby bird ate everything she brought to it. I was pleased to see this. Certainly the mother knew better than I how to feed her baby.
The following morning when I went to see how my captive(被俘虏的) was doing, I discovered it on the floor of the cage, dead. I was shocked! What had happened! I had taken excellent care of my little bird, or so I thought.
Arthur Wayne, the famous ornithologist, happened to be visiting my father at the time, hearing me crying over the death of my bird, explained what had occurred. “A mother mockingbird, finding her young in a cage, will sometimes bring it poison berries. She thinks it better for her young to die than to live in captivity.”
Never since then have I caught any living creature and put it in a cage. All living creatures have a right to live free.

Save Your Time, Money and Stress with Savvy (懂行,悟性)Rental Car Strategies
Renting a car can be expensive, confusing, and stressful — but it doesn't have to be. Here are several helpful strategies to save money, time, and stress on your next (and every) car rental.
Sign Up for Loyalty Programs
Rental car loyalty programs are free to join, so register for any programs you might use in the future. My favorite car rental loyalty program benefit is that I can skip the counter and head right to my reserved car. Some programs allow members to choose a car from the available pool. {#blank#}1{#/blank#}
Optimize Your Strategy
Do you really need a rental car from the airport? For instance, if your flight arrives at night, take a free hotel shuttle and pick up your car the next day. The car rental location might even be at your hotel or can pick you up (or deliver the car to you).{#blank#}2{#/blank#}
{#blank#}3{#/blank#}
For a city trip, you may not even need a rental car. Research whether mass transit(运输), taxi, Uber, bike rental, and other transportation methods will suffice(足够). Parking charges at downtown hotels may cost more than your car rental rate, so it may be doubly in your favor to give up a rental car. In some locations, a bike might be more efficient and economical than a car.
Search for Specials
{#blank#}4{#/blank#} In conjunction(结合)with your personal discount code, you may also find a last-minute rate, free rental day, or other promotion. My favorite annual travel deal is driving a car one-way out of Florida after Spring Break with rates as low as $1 per day.
Consider Alternative Rental Options
Major car rental companies might have an associated discount brand at your rental location, like Firefly for Hertz.{#blank#}5{#/blank#}
An independent or smaller local agency may fit your needs; like A1 or Lucky Owl in Honolulu. Many people prefer to check rates on Hotwire and Priceline, especially for last-minute rentals.
A.Rental rates are likely lower away from the airport, plus you might save the cost of an entire rental day.
B.I use discount-finding websites to track my car reservations.
C.Smaller brands, like Thrifty and Fox, might offer better service and lower rates.
D.In addition to saving time and offering freedom of choice, loyalty members earn points and receive special promotions.
E.Check car rental company websites for current specials.
F.Skip the Car
G.Use a bike
