28、Have you ever p  1  a few trees on Tree Planting Day? Each year, millions of people , both old and young, men and women, plant a lot of trees. But this may not be the best way to make your home a g   2   place.

    Last week, we visited a park in Hebei. We were s    3   to find most of the trees had been b  4   . The workers told us that the trees d   5    soon after they were planted, because they weren’t watered well enough. So workers burned them and cleaned the place for n  6   trees to be planted this year. On a card f   7    in one of the dead trees, a student w   8     ,“I hope this tree will grow up with me to b  9     the backbone（棟梁）of our country.”The workers said that the survival （存活）of the trees was really more important than how many trees were planted.

    Some people in Beijing now have a new idea that they can d    10    some money and let professionals（專業(yè)人士）plant and take care of the trees.
