6、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

7、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 2IIVocabulary 1. struggle 2. for 3. during 4. accepting 5. menial 6. indulgent 7. trouble 8. un-macho 9. refute 10.

12、期，（4）适应、解决或文化适应期。如果你无意或是有意地越线，与当地同事、朋友、家庭争吵或者惹恼他们，或者更加糟糕，触犯当局，你就会变成二等公民，尽管你当时并不如此想。大部分亚洲人会包容外国人，接受他们的奇怪习惯和行为，不仅仅是对他们有利之时出于利益（如，赚钱），更主要的 也是出于天生的礼貌和顾忌别人面子的克制。西方人却不应该利用这点。Unit 4Verpretations9. critique10.globalizedIII
