There are 7 (billion)of stars in the Galaxy,

Scientists have also 8 (discover)many
other galaxies in the universe.They are very far
away and their light has to travel for many
years to reach us.So how large is the universe?
It is 9

In 2025,the Shenzhou-21 spacecraft took
three astronauts-Tang Hongbo,Tang Shengjie
and Jiang Xinlin-to the China Space Station.
They would live and work there for six months.
Even in space,the astronauts can enjoy
delicious food.One day,they wanted to cook
chicken wings.They used a special space oven.
This oven is safe and works well in the no-
gravity space.First,they got the chicken wings
ready.Then they put the wings into the oven
and set the time.
After some time,the chicken wings were
cooked.They smelled very nice!The three
astronauts sat together and ate the tasty
chicken wings happily."Eating hot chicken
wings makes us feel warm and relaxed,"said
Tang Hongbo.
Cooking in space is different from cooking
on Earth.But with the special tools,the
astronauts can still have nice meals.This helps
them keep healthy and work better during their
long space trip.

V.信息摘录。
Do you know about space vegetables?
Have you ever eaten them?
Space vegetables are grown from seeds that
have been taken to and brought back from outer
space.When they are brought back to the
earth,these seeds will grow into the vegetables
that are bigger,healthier and more r
nutritious
(有营养的)than normal vegetables.However,
some
people worry about
eating
space
vegetables.They think that space vegetables might
be bad for us and could give us cancer.In fact,
there's no need to worry.Here are some facts that
we should know about space vegetables.
Space vegetables are grown from seeds that
are carefully chosen.After seeds are brought
back from space,they are tested to make sure
that the vegetables will be safe to eat.There are
no signs of radiation(辐射)after testing.
Space vegetables are better for us than
normal vegetables.For example,space tomatoes
stay fresh for twenty days,one week longer
than normal tomatoes.
Unlike genetically modified foods(转基因
食物),space vegetables have】
not been
genetically changed.This means that no
new
genes are put into the space vegetables,so we
can eat them safely.

Space travel used to be only for astronauts,
but this will change in the future.With new
technology,more people will have the chance to
travel to space and even visit other planets.
In the next 30 years,space tourism will
become popular.Companies are developing
reusable rockets that can reduce the cost of
space travel.This means ordinary people may be
able to take a short space trip for a reasonable
price.During the trip,they will fly around the
Earth,see the beautiful blue planet from space,
and even experience weightlessness -floating
like astronauts!
Scientists also plan to build a lunar base on
the moon.This base will be a home for
astronauts and scientists.They will live there to
study the moon and do experiments.Later,it
may become a stop for people traveling to
Mars.The trip to Mars will take about six
months,but it will be an amazing journey.People
will live in special spaceships with all necessary
things,like food,water,and exercise equipment.
However,space travel also has
some
challenges.It can be dangerous because of
radiation and unexpected problems in space.
Travelers will need to train hard to get used to
the space environment.Also,we need to keep
space clean-we shouldn't leave trash in space.
Despite these challenges,space travel is an
exciting future dream.It will help us learn more
about the universe and bring people closer to
the stars.
