From the first use of the rocket to carry satellites into space to the setting up of space stations，human beings have been putting great effort into space research.And so far，we have achieved many successes.But there are still numerous tasks in front of us and we should not cease trying to progress. The international space station is an important step we should take in space exploration.It is not only helpful but also essential.It provides a proper space environment for many experiments that we have wanted to do for a long timE.It is also a base for the observations of the earth and the universE.It could also be an important base for later travels to the moon and Mars.In a word，if we want to explore space more，the first thing we should do is to set up a space station. As the space station costs a lot of money，it is hard for one country alone to establish onE.The USA seems to be the only country that has the ability to build a space station alone，and it has tried to do so，but not very successful.So it aggregated many other countries to work on it together.Though it is still extremely expensive，it is much cheaper than doing it alonE.It is really a job that needs everyone’s effort and will benefit everyonE. But even so，the funds needed are still a big problem.As for the USA，it seems that it has too many things to spend its money on.Although it is the richest country in the world，it has much debt every year.It has to make arrangements about its finance，and try to find a balance in all these issues. 56.What is the author’s attitude towards building and developing the international space station? A.SupportivE.B.Doubtful. C.Critical.D.DissatisfieD. 57.From Paragraph 2 we learn that________. A.the necessity of building the international space station is not realized now B.many experiments have been done in the international space station C.the international space station is necessary for people to explore space more D.people have traveled to Mars from the international space station 58.Which of the following is NOT a reason for countries’ cooperation in building the international space station? A.That it requires a lot of money. B.That it needs everyone’s effort. C.That it will benefit every participating country. D.That it is too far away from the earth. 59.Which of the following aspects about building the international space station is NOT mentioned in the passage? A.Difficulties. B.Cooperation. C.SignificancE. D.Specific arrangements.
