1.表示客观的真理用一般现在时，主语为单数第三人称地球，后面的谓语动词travel要用第三人称单数形式travels。
2.本题的含义是现在你能看到学生在山上植树吗？看到某人正在做某事可用see sb doing sth，故空格填plant的现在分词planting。
3.问某人在哪里，某人应该正在做某事，故用现在进行时，结构为be+现在分词，故填is cleaning。
4.in a few years通常用于将来时，故使用be的将来结构will be。
5.本题的含义是他想要我的帮助，所以我停下来去帮助他，表示停下来做另一件事应说stop to do，故填to help。
6.表示忙于做某事通常说be busy （in）doing sth，故填planning。
7.本题的it是形式主语，真正的主语位于句尾，用动词不定式to do，否定形式是not to do，故本空填not to give。
8.使役动词make后应跟动词原形作补语，故本空还是填work。
9.本题中有个过去的时间短语a moment ago，故本题使用过去时，fall的过去式为fell，故空格填fell。
10.本题为祈使句，它的否定形式为don’t+动词原形，故本空应该填don’t frighten。
