【解析】

【1】you是原句动词sweep的施动者，受动者是the floor，变为被动语态后二者角色需互换，基本结构为“受动者+be +过去分词+（by+施动者）+其他”。the floor是单数第三人称，系词需用is；根据句意结构，可知填Is the floor swept（by you）every day?。

【2】people是原句动词grow的施动者，受动者是tea，变为被动语态后二者角色需互换，基本结构为“受动者+be +过去分词+（by+施动者）+其他”。tea是单数第三人称，系词需用was；根据句意结构，可知填Was tea grown by people in the old days?。

【3】we是原句动词learn的施动者，受动者是Lesson 60，变为被动语态后二者角色需互换，基本结构为“受动者+be +过去分词+（by+施动者）+其他”。Lesson 60是单数第三人称，需借助has been+过去分词构成被动结构；根据句意结构，可知填Lesson 60 has been learned by us.。

【4】we是原句动词see的施动者，受动者是many of the stars，变为被动语态后二者角色需互换，基本结构为“受动者+be +过去分词+（by+施动者）+其他”。情态动词后接原形动词，根据句意结构，可知填Many of the stars can’t be seen by us.。

【5】China是原句动词set的施动者，受动者是Man-made satellites，变为被动语态后二者角色需互换，基本结构为“受动者+be +过去分词+（by+施动者）+其他”。satellites是复数人称，需借助have been+过去分词构成被动结构；根据句意结构，可知填Man-made satellites have been sent up into space by China.。

【6】they是原句动词plant的施动者，受动者是trees，变为被动语态后二者角色需互换，基本结构为“受动者+be +过去分词+（by+施动者）+其他”。will后接原形动词，根据句意结构，可知填The trees will be planted tomorrow.。

【7】I是原句动词see的施动者，受动者是he，变为被动语态后二者角色需互换，基本结构为“受动者+be +过去分词+（by+施动者）+其他”。he是单数第三人称，系词需用is，根据句意结构，可知填He is seen to go to school every day.。

【8】our teacher是原句动词make的施动者，受动者是us，变为被动语态后二者角色需互换，基本结构为“受动者+be +过去分词+（by+施动者）+其他”。us居主语位置需用主格形式we，系词用were；make sb. do sth.让某人做某事，固定短语，在被动结构中需恢复省略的不定式符号to；根据句意结构，可知填We were made to close our eyes in the game.。
