Assembly of the International Space Station (ISS) began with the launches of the Russian control module Zarya on November 20, 1998. (ASSEMBLE) Astronauts exercise regularly in order to minimize muscle and bone loss. Space exploration can help us to discover new knowledge about own planet. (KNOW) Sixteen nations were involved in the construction of the ISS. (CONSTRUCT) Just as on Earth, recreation and sleep are important to good health when working in space. (CREATE) The food that the astronauts eat is mostly frozen and canned.(FREEZE) Crews are not only responsible for science, but also for maintaining the station.(RESPOND)

It is necessary that you (to come) a couple of days before the others. He talks about Rome as though he (to be) there himself. After the Challenger tragedy the military experts insisted that a new Shuttle (to be) built. It is desirable that international space cooperation (to give) significant economic advantage for countries involved. If he had worked more slowly, he (not make) so many mistakes. The accuracy of the system would be improved if signals (to transmit) on two frequencies simultaneously. If all submersibles had had autonomous principle of operation (to become) much more useful.

Some materials are cooled almost to -273C so that they (to become) superconductors. Even if I had a dictionary, I don't believe I (to be able) to write the test. Tsiolkovky proposed that the liquid propellant (to use) for space travel. If you (to be) on the first manned space station your task would be to study the stars and planets. If I had this tool, I (to give) it to you. You are the only person she (to listen) to. It is necessary that stability of space vehicles (to be) artificially provided.
