Why should mankind explore space? Why should money, time and effort be spent exploring and researching something with so few apparent benefits? Why should resources be spent on space rather than on conditions and people on Earth? These are questions that, understandably, are very often asked.
Perhaps the best answer lies in our genetic makeup as human beings. What drove our ancestors to move from the trees into the plains, and on into all possible areas and environments? The wider the spread of a species, the better its chance of survival. Perhaps the best reason for exploring space is this genetic tendency to expand wherever possible．
Nearly every successful civilization has explored, because by doing so, any dangers in surrounding areas can be identified and prepared for. Without knowledge, we may be completely destroyed by the danger. With knowledge, we can lessen its effects.
Exploration also allows minerals and other potential resources to be found. Even if we have no immediate need of them, they will perhaps be useful later. Resources may be more than physical possessions. Knowledge or techniques have been acquired through exploration. The techniques may have medical applications which can improve the length or quality of our lives. We have already benefited from other spin-offs including improvements in earthquake prediction, in satellites for weather forecasting and in communications systems. Even non-stick pans and mirrored sunglasses are by-products of technological developments in the space industry!
While many resources are spent on what seems a small return, the exploration of space allows creative, brave and intelligent members of our species to focus on what may serve to save us. While space may hold many wonders and explanations of how the universe was formed or how it works, it also holds dangers．The danger exists, but knowledge can help human being to survive. Without the ability to reach out across space, the chance to save ourselves might not exist.
While Earth is the only planet known to support life, surely the adaptive ability of humans would allow us to live on other planets. It is true that the lifestyle would be different, but human life and cultures have adapted in the past and surely could in the future.Why does the author mention the questions in Paragraph1?

While I was in 9 th grade, I built a circuit (电路装置) for the traffic system of our city. After getting the first prize. I got this valuable advice from my father; “Do whatever interests you, and don’t let the work challenge you, make sure you are challenging that work.”
I have always preferred the projects which are challenging and related to real life problems. I clearly remember building a shipping program several years ago. I divided the whole project into several small sections. When I understood it clearly, used my brainstorming skill on it, and gave some basic ideas. Then I asked my professor for help before jumping into coding (编码). At first, I did not know how to ask questions correctly and always asked the question “How do I do it?” As I kept working and discussed with my professor, I became more comfortable and those “how ”questions soon turned into “what if I do this and that” types of questions.
It took me four days to write the code. The desire to solve the problem kept me sleepless all nights brainstorming in even greater details. Every time I saw my program running smoothly, I exploded with joy. I still remember the last day of my work. I was getting some problem and didn’t know what to do. At that moment, a man came in to clean. He has headphones, and he was dancing while cleaning the room. Seeing this, I burst out laughing. That moment calmed me. I regained energy and interest and started to work again, and soon I fixed the problem.
My success in the project proved that breaking up a large problem into small parts could help find a possible solution. Discussing the problem with others was also very beneficial. Now I have gained the confidence to attempt any kind of project.

Due to the increasing number of violence acts produced in schools all over the world, more and more parents prefer to have their children educated at home rather than at school. This way they can assure their safety and well-being，although teachers and school representatives are trying to improve the situation in schools by increasing the number of the persons in charge of the safety of the students．
The main reason for violence acts are the films and cartoons that fill the children’s time．They want to do everything．they watch on TV and never think at the consequences，and they may hurt a classmate or a teacher．
On the other hand, parents are not fully satisfied with the children’s results obtained in classes and they consider private classes would have better results．
When a teacher has to watch 30 students in class he can’t probably see what each of them is doing，how he is writing，or if he understands the explanations．At home the teacher can explain in details everything the child doesn’t understand as many times as he considers proper．
And many times，the child grows fond of the teacher at home，who becomes his best friend，and who helps him whenever he needs someone to talk to．
However, the best solution would be a mixture between the education received at school and that at home，because school makes children communicate and socialize．Keeping a child at home for fear that there might be something bad happening to him only makes the child’s character weak and prevents him from knowing what real life is．Staying in a crystal ball only does harm to the child．
All in all，schools have been created to help children，not to harm them，so it’s best to keep children in these special places，where they learn，laugh，have fun and make new friends．

55．Parents prefer to have their children educated at home because the following EXCEPT that
A．More and more violence acts occur in schools
B．Parents want to improve their Children's grades
C．Parents are concerned about their children’s safety
D．The education system is far from satisfactory

People say time is relative．But relative to what．I do know that sometimes time“seems”to be moving slower．Remember Christmas Eve when you were a child? It was the longest night of the year．It lasted forever! And now it seems like I just paid my bill yesterday．．．and it’s due again!
People tell me all too frequently…I need more time! Oh ，really?…Mother Teresa，Michelangelo，and Helen Keller all had 24 hours a day．Look what they did with their time!
Is it that we need to manage our time better…or our priorities(重点)?You’ve heard the expression“first things first．”The first step in understanding the power of time is to understand that it is limited．Why is it then that some people get a lot more done? We know the answer．They use their time smartly．
One day an expert on time management was speaking to a group of students and announced a quiz．He pulled out a wide-mouthed jar．Next，he placed about a dozen fist-sized rocks，one at a time , into the jat, until no more would fit．“Is it full?” he asked．”Yes，”responds the class．”Oh really?” he asked．So he took out a bucket of gravel(砂砾), which he managed to work down into the spaces between the larger rocks．“Is it full now?” he asked．
Wising up，one answered，‘'Probably not．”Sure enough, he took out a bucket of sand，which he poured into the empty spaces．”Is it full now?” he asked．”No,” reply the students confidently．So he took a glass of water and filled it in．Then he asked，“What is my point?’’
One said，‘'No matter how full your schedule is，if you try really hard，you can always fit some more things into it！”
“No，”the speaker replied，“It tells us if you don’t put the big rocks in first, you’ll never get them in at all．’’
What are the big rocks? The things you should put in to your jar first．
The rich don’t get 25 hours and the poor don’t get 23…we all get the same．Let’s use them wisely! Invest your time wisely!
49．What does the point of the quiz lie in_______.
A．How to put more things into ajar． B．How well the students learn the lesson．
C．How to get more done in limited time D．The skill and order is very important．
