1. 次の英文を読んで (1) ~ (5) の問いに答えなさい。
Have you ever dreamed of traveling in space? I have thought of going into space as
an astronaut so many times. Traveling beyond the earth is always a great dream and
hope for humanity. But as everyone knows, it is not easy to be an astronaut. There are
many people who want to try to get into space flight programs all around the world.
So first, you have to pass extremely difficult selection processes to even participate in
the training and testing used to prepare potential astronauts for operating in and living
F )
in space. The training itself is so hard that it is very difficult (A) complete. (
those that pass the training, only a few can actually experience the trip into space.
Every time I see the news about the manned space flights on TV, it does sound like
something impossible for a regular person like me.
(G
), there was a recent event that really surprised me in September 2021. They

successfully. As a surprise, this mission was an "All-
Civilian" flight. The four people in the Crew Dragon were not professional astronauts
from other space agency programs. A billionaire booked the Crew Dragon capsule last
year and picked three normal people to ride (B) him. It was the VERY first totally
private mission to orbit. The stories of how the people had been chosen and how the trip
succeeded were not only amazing but also very heart warming. Watching this news
reminded me (C) the excellent idea about Space elevators. This is a promising scientific
technology that could take us into space much more (K) in the future.
( H ) JSEA (Japan Space Elevator Association), the concept of a Space elevator
would make reaching orbit in space easier and faster (D) using Centrifugal force and
Earth's gravity instead of rockets. Engineers estimate it requires a cable that is about
100,000km long and more than 100 times as strong as steel. So of course, it sounds like
a challenging development. Also, the space elevator would require much less energy to
lift cargo and people into orbit and be significantly more eco-friendly. As they continue
to work on advancing technology, the space elevator may become a reality (E) we know
it. With the space elevator, traveling into space would no longer be an impossible dream
for us, ordinary people. Just talking about it, I get totally excited and can't help hoping
to experience the situation of looking down on the earth from the space one day.
