阅读理解        What does an astronaut (宇航员) eat in space? This is a question thatwill 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 choo from like nuts, chicken, beef, afood, 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 EarthB．drank milk through StrawsC．ate dehydrated food                 D．ate with a fork; knife; and spoon2．In today's space-age, astronauts  __________A．can only eat fruit and noodlesB．can't eat anything in a natural wayC．can u the refrigerators to store the foodD．can eat many kinds of food like on Earth.3．The US space agency NASA has found out that ________in space.A．an astronaut can eat more than on Earth.B．an astronaut eat less than on EarthC．an astronaut eat as much as on EarthD．an astronaut doesn't have to eat food at all.4．Astronauts eat three meals a day in space, and they can also __________.A．cook for themlves    B．drink some beerC．smoke      D．eat snacks5．Scientists are always experimenting and trying out different space foods that can be offered to astronauts  ________.
