1.表示客觀的真理用一般現在時，主語為單數第三人稱地球，后面的謂語動詞travel要用第三人稱單數形式travels。
2.本題的含義是現在你能看到學生在山上植樹嗎？看到某人正在做某事可用see sb doing sth，故空格填plant的現在分詞planting。
3.問某人在哪里，某人應該正在做某事，故用現在進行時，結構為be+現在分詞，故填is cleaning。
4.in a few years通常用于將來時，故使用be的將來結構will be。
5.本題的含義是他想要我的幫助，所以我停下來去幫助他，表示停下來做另一件事應說stop to do，故填to help。
6.表示忙于做某事通常說be busy （in）doing sth，故填planning。
7.本題的it是形式主語，真正的主語位于句尾，用動詞不定式to do，否定形式是not to do，故本空填not to give。
8.使役動詞make后應跟動詞原形作補語，故本空還是填work。
9.本題中有個過去的時間短語a moment ago，故本題使用過去時，fall的過去式為fell，故空格填fell。
10.本題為祈使句，它的否定形式為don’t+動詞原形，故本空應該填don’t frighten。
