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(基因构成) 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 (潜在的) 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 (副产品)  of technological developments in the space.
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.

Scientists have transformed men’s minds into a virtual(虚拟的)woman’s body in an experiment that could throw light upon how humans distinguish themselves form others.

In a study at Barcelona University, men wore a virtual reality headset that allowed them to see and hear the world as a female character. When they looked down, they could even see their new body and clothes.

The “body-swapping” effect was so convincing that the men’s sense of self was transferred into the virtual woman, causing them to react to events in the virtual world they were immersed(沉浸). “This work opens up another avenue for virtual reality, which is not just to transform your sense of place, but also your sense of self,” said Mel Slater, “If you can temporarily give people the illusion that their bodies are different, then the evidence suggests it also affects their behavior and the way they think. They can have new experiences: a person who is thin can know what it is like to be fat. A man can have an experience of what it’s like to be a woman.”

During the experiment, a “female” approached and hit the face of the character another man was playing. “Their reaction was immediate,” said Slate. “They would take in a quick breath and maybe flinch(退缩). The more people reported being in the girl’s body, the stronger physical reaction they had.” But in all cases, the feeling was temporary and lasted only as long as the study.

The study shows that our minds have a very fluid picture of our bodies. The research is expected to shed light on the puzzle of how our brain tells the difference between a part of our own body and something else in the wider world. Thus the work might improve the conditions for those who have experienced strokes by placing them in a world that helps them to use their bodies to the full again.

1.How can a man’s mind get into a woman’s body?

A.by distinguishing themselves from women

B.by taking part in an activity actively

C.by wearing a special device(设备)

D.by transforming his sense of place

2.Of the following statements, which we can’t infer from the passage?

A.Men in the experiment can temporarily have the wrong feeling that they are women.

B.When hit, the men in the virtual world will react angrily to it.

C.As soon as the experiment is finished, the men will return to the normal state

D.Probably, this study can be applied to medical fields and benefit humans.

3.What is the author’s intention of writing this passage?

A.to introduce an interesting and advanced study

B.to inform us of the latest development of virtual reality

C.to illustrate the importance of virtual reality

D.to build up our confidence to fight stroke
