阅读理解 What does an astronaut (宇航员) eat in space? This is a question that
will puzzle many, as people rarely think of that. In the early space-travel
years, astronauts ate dehydrated (脱水的) foods that were eaten through
straws(吸管). In today's space-age, the food that they eat is totally different.
They eat food in the same way as people do on Earth.
Astronauts are able to prepare and eat a variety (多样化)of foods in
space. Some can be eaten in their natural form, like fruits; while some need to add water, like noodles. However, there are no refrigerators, so the food has
to be prepared and eaten without being Stored for a long time. When the
astronauts are hungry, they simply eat the food by opening the food ackages and with a fork, knife, and spoon.
Just like people on Earth, astronauts also eat three meals a day which
include breakfast, lunch and dinner. Sometimes they also eat snacks. The US
space agency NASA has found out that an astronaut's diet reduces(减少) by
about 70% on a space mission, though he has a wide range of foods to
choose from like nuts, chicken, beef, seafood, and candies. Drinks in the
spaceship include coffee, tea, juices, and lemonade.
Astronauts can also request a particular food that they would like to have in space. Scientists are always experimenting and trying out different space
foods that can be offered to astronauts when on space missions.1．In the early space-travel years, astronauts ___________.A．ate the same food as on Earth
