Translation (E-C)Directions: Please put the following into Chinese.III Translation (E—C)Directions: Please put the following into Chinese.Mangoes should be planted in full sun and well drained soil, however because of occasional frost in the salt river basin it is often a good idea to plant near your home or under the canopy of a larger tree. Think what would be the warmest part of your yard during the winter months and that will probably be the best suited location for your mango tree, dont worry about summer sun and heat, they love it. When removing the tree from its container it is extremely important not to damage or disturb the roots, especially the tap root. Never pull the tree from the container by the trunk, it is most often the cause of irreversible shock. Loosen the soil 1-3 feet around the planting site, dig a hole twice as wide as the container and no deeper than the root ball, though do loosen the soil at the bottom of the hole. Carefully cut the bottom of the nursery container and place the tree with the remaining pot in the hole, the root ball should be 1-2 inches above the surrounding soil to allow for settling and better drainage. Next cut the sides and remove the container, now you may back fill the hole. Use any remaining soil to build a berm around the tree 3-4 inches high and fill with water. Use B-1 also for the first few times you water, just follow the instructions on the bottle. 芒果应该在充足的日照下和通风良好的土壤中种植。然而，在索尔河谷，霜冻时有发生。因此，靠近家或在大树下种植芒果不失为妙招。想想看，在冬天那几个月里，你家后院何处最暖和，那便是你的芒果树最适宜的落脚地。不用担心夏日的太阳和热浪，芒果喜欢着哩。从容器中移动果树时，切不要伤及或惊扰了根系，特别是主根，这极其重要。永远不要逮着树干将果树从容器中拔出，这往往给它造成不可逆转的冲击，是此类伤害的元凶。在种植处疏松1-3英尺的土壤，掘一个两倍于容器大小的坑。坑底须疏松一下土，但坑深不要超过根垛。切割育苗容器的底部时，要仔细着点。将树苗连同余下的罐一同放到坑里。考虑到周围环境和良好通风，根垛应高于周边土壤1-2英寸，以保障树苗安顿生根、排水通畅。接下来，要修整各边，移走容器。现在，你可以回填土坑啦！用余下的土绕树修一圈3-4英寸高的崖颈，里面灌满水。头几次浇水的时候，也添加上B-1，只须根据瓶上指示做即可。Unit 2II．Vocabulary 1. struggl
