1 梦想之源。
（1）乐乐的梦想源于一篇介绍航天员太空生活的文章。下面是这篇文章中的一个片段。
航天员的太空生活——饮食篇
在太空吃饭的规矩比地面复杂得多。太空舱内备有简易餐桌，餐桌具有磁性，能吸住金属餐具。吃饭时，航天员必须先把脚固定在地板上，身体也需用座椅上的带子系紧，以免飘浮。吃饭的动作不能太大、太猛，以免食物飘走。夹菜要夹准、夹牢，最好用叉子。食物进嘴时要快，以免食物“飞走”。吃饭时严禁说话聊天，否则会使食物飞出嘴外，造成生活舱的环境污染，同时稍不注意还会吸进鼻腔，容易发生危险。
太空食品是由航天系统的专家们精心研制开发的，品种丰富多样。每餐饭都是用食品袋提前包好的，每个食品袋上均标有哪一天哪一餐的字样，每袋食品仅供一名宇航员食用。太空食品均为脱水食品，临吃前要用注射器注入一定数量的水，然后放进烤箱里加热。
下面是一份太空食品袋的说明，请你根据《航天员的太空生活——饮食篇》中的描述将这份太空食品袋说明中的事项填写完整。

（2）请你和乐乐一起读一读这篇关于太阳、地球和月球的英语小短文，并回答问题。
London Cat and Paris Mouse are in a spaceship. London Cat says, “We are in space. This is the sun. It is very big. This planet（行星）is very near to the sun. It's very hot. That planet is very far from the sun. It's very cold. The Earth is not very near to the sun. And the Earth is not very far from the sun. It is not too hot or too cold. The Earth is a very beautiful planet.” Paris Mouse says, “Oh, I have learned a lot today!”
Question: Is the Earth near or far from the sun?

（3）乐乐想着，未来人类会不会在太空中生活呢？太空中会不会也有学校呢？他把自己梦想中太空学校的样子写了下来，你能帮他完成吗？（选词填空）
