3．Once upon a time，there was a wonderful old man who loved everything on the land--animals and plants．
One day while walking through the woods，the old man found a cocoon of a butterfly．He took it home．A few days later，a small opening appeared； he sat and watched the butterfly for several hours as it struggled to force its body through that little hole．Then it seemed to stop making any progress．It appeared as if it had gotten as far as it could and it could go no farther．Then the man decided to help the butterfly，so he took a pair of scissors and cut the remaining bit of the cocoon．The butterfly then came out easily．
But it had a swollen body and small，shriveled wings．The man continued to watch the butterfly because he expected that，at any moment，the wings would enlarge and expand to be able to support the body，or they would be smaller．Neither happened!In fact，the butterfly spent the rest of its life crawling around with a swollen body and shriveled （枯萎）wings．It never was able to fly．
What the man in his kindness and hurry did not understand was that the struggle required for the butterfly to get through the tiny opening was nature's way of forcing fluid from the body of the butterfly into its wings so that it would be ready for flight once it achieved its freedom from the cocoon．
Sometimes struggles are exactly what we need in our life．If we were allowed to go through our life without any difficulties，it would cripple （无能） us．We would not be as strong as what we could have been．And we could never fly．

D．it came out of its cocoon without enough struggle

D．It's not hard for the butterfly to come out of the cocoon．

5．Five years ago，David Smith wore an expensive suit to work every day．"I was a clothes addict，"he jokes．"I used to carry a fresh suit to work with me so I could change if my clothes got wrinkled．"Today David wears casual clothes-khaki pants and sports shirt-to the office．He hardly ever wears a necktie．"I'm working harder than ever，"David says，"and I need to feel comfortable．"
More and more companies are allowing their office workers to wear casual clothes to work．In the United States，the change from formal to casual office wear has been gradual．In the early 1990s，many companies allowed their employees to wear casual clothes on Friday，but only on Friday．This became known as"dress-down Friday"or"casual Friday"．"What started out as an extra one-day-a-week benefit for employees has really become an everyday thing．"said business consultant Maisly Jones．
Why have so many companies started allowing their employees to wear casual clothes？One reason is that it's easier for a company to attract new employees if it has a casual dress code．"A lot of young people don't want to dress up for work，"says the owner of a software company，"so it's hard to hire people if you have a conservative （保守的） dress code．"Another reason is that people seem happier and more productive when they are wearing comfortable clothes．In a study conducted by Levi Strauss Company，85 percent of employers said that they believe that casual dress improves employee morale（士气）．Only 4 percent of employers said that casual dress has a negative effect on productivity．Supporters of casual office wear also argue that a casual dress code helps them save money．"Suits are expensive，if you have to wear one every day，"one person said．"For the same amount of money，you can buy a lot more casual clothes．"

2．Six volunteers are about to find out what it would be like to live on Mars without ever leaving the Earth．Three men and three women will spend eight months living in a special place on the side of a volcano in Hawaii．They are part of an experiment that is designed to mimic（模仿）life on Mars．Their mission began on October 15，2014．NASA says it could send astronauts to Mars as early as the 2030s．The mission would take more than two years，so NASA needs to know how people would react to living in a small group，isolated from the rest of the world，for such a long time．Some people may become depressed or bored living under those conditions．By studying people living in similar conditions here on Eares NASA hopes to learn how to choose the most suitable people for a space mission，and how to help them get along．
They will live in a two-story building．The ground floor is about 86square meters，roughly the size of a small two-bedroom apartment．It includes shared areas like kitchen，dining room，bathroom，laboratory and an exercise room．The upstairs is less than half the size of the downstairs．It contains another bathroom and six small bedrooms．The building is located in an abandoned quarry（采石场）about 2，400meters up the side of Mauna Loa，the second biggest volcano in the world．It is constantly monitored for signs of volcanic activity．NASA chose the location because the appearance looks very similar to Mars．
To make it more like being on Mars in the future，they are only able to communicate by email during the experiment．Meanwhile，there will be a 20-minute delay between the time when a message is sent and that when it is received．When they go outside，they will have to suit up in full spacesuits，just as if they were on Mars．
The commander is Martha Lenio，a 34-year-old Canadian．During the mission，she will run experiments on growing food．The other members have backgrounds in physics and so on．None of them are astronauts．

21．When will the six volunteers end their mission about mimicking life on Mars？A
A．On June 15，2015．
B．On October 15，2015．
C．On October 15，2030．
D．On June 15，2032．
22．What's the main purpose of the experiment？B
A．To monitor signs of volcanic activity．
B．To prepare for a space mission to Mars．
C．To train the six people to become astronauts．
D．To study the difference between men and women．
23．Mauna Loa was chosen as the experimental site becauseC．
A．it is located near a rocket base
B．other people can hardly find the location
C．its landscape is so much like that of Mars
D．it is a safe place to conduct the experiment
24．What can be inferred from the passage？D
A．Martha is a famous expert on agriculture．
B．The six volunteers will be sent to Mars in 2030．
C．All the experimental activities are done in doors．
D．It takes about 40minutes to get a reply to an email．
3．I'm fully convinced that nothing is impossible to a willing heart．
