【解析】
1. 空格修饰名词vegetables,需用形容词,方框中fresh为形容词,故填fresh;
2. 由时间状语last year可知用一般过去时,方框中explore的过去式是explored,符合“去年学校旅行探索农场”的句意;
3. wastewater plant是固定表达“废水厂”,方框中plant符合语境;
4. put up表示“搭建”,后接名词tent(帐篷),符合学校旅行的场景;
5. didn't后接动词原形,方框中realize是动词原形,符合“没意识到”的句意;
6. agree with是固定搭配“同意”,用动词原形agree;
7. many后接名词复数,leaf的复数形式是leaves,符合“树上有很多叶子”的句意;
8. space exhibition是“太空展览”,方框中exhibition符合语境;
9. 由时间状语last year可知用一般过去时,teach的过去式是taught,符合“李老师去年教我们英语”的句意;

1. fresh 2. explored 3. plant 4. tent 5. realize 6. agree 7. leaves 8. exhibition 9. taught 10. diary
