As we continue to explore farther out into our solar system and beyond, the question of humans living on other planets often comes up. Manned bases on the Moon or Mars for example, have long been a dream of many. There is a natural desire to explore as far as we can go, and also to extend humanity's presence on a permanent(永久的) or at least semi-permanent basis. In order to do this, however, it is necessary to adapt to different extreme environments. On the Moon for example, a colony must be self-sustaining( 自 立 的 ) and protect its inhabitants from the airless, harsh environment outside.
Mars, though, is different. While future bases could adapt to the Martian environment over time there is also the possibility of modifying(改变) the surrounding environment instead of just co-existing with it. This is the process of terraforming - adjusting Mars’ atmosphere and environment to make it more Earth-like. But the bigger question is, should we?
One of the main issues is whether Mars has any native life or not and if it does, should it be preserved(保护) as much as possible? If the answer is yes, then large-scale human settlements on Mars should be completely off-limits. Small colonies might be fine, but living on Mars should not be at the expense of any native habitats, if they exist. If Mars is home to any indigenous life, then terraforming should be a non-issue; it simply should not be done.
What if Mars is lifeless? Even if no life exists there, that untouched and unique alien environment needs to be preserved as it is as much as possible. We’ve already done too much damage here on our own planet. By studying Mars and other planets and moons in their current natural state, we can learn so much about their history and also learn more about our own world. We should appreciate the differences of other worlds instead of just transforming them to suit our own ambitions.

“I believe in holding onto traditions because they helped our family flourish（兴旺）in a new country. But this concept is more concretely expressed this way: I believe in feeding monkeys on my birthday — something I’ve done without fail for 35 years.
In the Burmese jungle, monkeys are as common as pigeons. But in America, feeding monkeys means violating the rules.
As a kid, I thought that was cool. I learned English through watching bad television shows and expected that I was the chosen warrior（勇士）sent to defend my family. Dad and I would go to the zoo early in the morning, just the two of us. When the Coast was clear, I would throw my peanuts to the monkeys.
I never had to explain myself until my 18th birthday. It was the first year I didn’t go with my father. I went with my friends and arrived 10 minutes after the zoo gates closed. “Please,” I begged the zookeeper, “I feed monkeys for my family, not for me. Can’t you make an exception?” “Go find a pet store,” she said.
If only it were so easy. That time, I got lucky. I found out that a high school classmate trained the monkeys for the movie Out of Africa, so he allowed me to feed his monkeys. Once a man with a pet monkey suspected that my story was a ploy — that I was an animal rights activist out to liberate his monkey. Another time, a zoo told me that outsiders could not feed the monkeys without violating the zookeepers’ collective bargaining agreement. Once in a pet store, I managed to feed a marmoset（狨）being kept in a birdcage. Another time, I was asked to wear a special suit to feed a laboratory monkey.
It’s rarely easy and, yet, somehow I’ve found a way to feed a monkey every year since I was born.

A.Joke. B.Trick.
C.Excuse. D.Adventure.
4.How is the fifth paragraph mainly developed?
A.By providing examples. B.By giving explanations.
