题目

阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。 Celebrate Arbor Day (植树节) People in many countries observe Arbor Day. If you want to make a contribution to our planet, you could start by reminding your family and neighbors of the importance of planting trees. Following are some steps to help you choose and plant a tree. 1 Choose a tree that will grow well in your area. You should consider: how big the tree will grow, how long it will live, whether it produces fruit or flowers, and whether it attracts birds and other wildlife. 2 Decide where you will plant your tree. Remember that the tree's root system and branches will need space to spread out and up, so you do not want to place it too close to your house or other buildings or other trees. 3 Prepare a hole that is twice as wide as the root system of your tree, keeping in mind that it should not be too deep, as the tree needs to be level with or slightly taller than the ground around it. With a shovel, scrape the sides and bottom of the hole-this will help the roots work their way through the soil. 4 If your tree comes wrapped with burlap (粗麻布) around the roots, simply pull the cloth loose enough so that it falls around the root system in the hole. 5 Separate the roots slightly to encourage them to spread. Root tips die when exposed to light and air, so get the tree in the ground as quickly as possible. 6 Create a shallow depression (凹地) around the tree to collect water. Thoroughly water the tree and add mulch around its base to help keep the ground around the tree moist (潮湿的). Because keeping your tree alive and thriving is an ongoing task. A. It's time to dig. B. It's time to water the tree. C. Then organize your own tree-planting event! D. If your tree comes in a container, be sure to move it. E. Then fill in the space around it with soil and pat it down. F. Keep in mind that you should water it regularly and take good care of it. G. And if you want to plant in a public space, make sure to get permission first from the local town board. 答案：【1】C【2】G【3】A【4】E【5】F
