“Being in space is an exhilarating experience,” recalls astronaut Buzz Aldrin, member of the three-man
crew which made history nearly 50 years ago when they (1) ________ in being the first melt ever to set
foot on the Moon. ‘Just being able to float around is amazing. Unfortunately, the space suits were quite
restrictive so we weren’t able to move about very easily. They made the job of collecting moon rock and
soil to bring back to Earth much more difficult. The surface of the Melon is covered in a (2) ________
and because there isn’t any wind or weather on the Moon, Neil’s famous first footprint should still be
there until it is disturbed by other visitors. “On our (3) ________ to Earth, we were put in quarantine. It
was still not known whether life existed on the Moon and it was feared that organisms from the Moon
could infect animals and plants on Earth. Hopefully, in the next 25 years man will be setting up (4)
________bases on the Moon or even on Mars. I don’t see much point in just sending astronauts there.

Trends in worldwide energy use point up an urgent need to expedite the development of technology that
can wean the world % from fossil fuels. Many experts contend that the recent increases in the price of oil
will not be followed, as in the past, by an easing off after a year or two. Even if that were not the case, the
world would have to be concerned about inevitable constraints on supply. Gasoline and diesel engines in
motor vehicles consume the (1) ________ majority of fossil fuel used outside power generation. The only
technology currently in the pipeline for rescuing transportation from a very serious oil crunch is (2)
________ vehicles operating with hydrogen fuel-cell engines. Private industry, long a mere bystander in
the development of the hydrogen economy, is now (3) ________ the way to develop affordable and
environmentally desirable hydrogen fuel-cell vehicles. The United States government is spending about $
100 million per year for research on hydrogen vehicles and hydrogen-storage technology. Major
automobile manufactures claim they will have (4) ________ hydrogen cars by 2015. These cars, it should
be noted, will produce no greenhouse gases. Like any new fuel technology, hydrogen will require
infrastructure. Plants to generate usable hydrogen, pipelines to move it, and depots in which to store it,
must be put in place. Stations for refilling a vehicle’s hydrogen tank must be as common as ordinary gas
stations before many consumers will venture onto the open road with hydrogen cars, yet this is not an
unrealistic scenario. Most probably, existing oil and gasoline infrastructure can be affordably – and
incrementally – (5) ________ to hydrogen infrastructure.

mountainous land. Also, a very useful communication system was developed between the different
sections of the wall. Smoke signals were used to send messages quickly anywhere along the wall’s length.
Now, the Great Wall is China’s most popular tourist attraction. It has suffered some decay and destruction
over the centuries. Parts have been (4) ________ by the wind and weather. Other sections have been
