Viết thư phản hồi Dear Annie, Hope you are doing fine. My departure date for New Zealand is drawing near, and I am busy with last-minute preparations. As you know, I have enrolled at an institute called 'Practical English' in Wellington, for a six-month Advanced course, full-time. It is quite expensive but I am hopeful of improving my English skills, especially pronunciation. To assist in covering the costs of my study, I aim to find a part-time job. Not only are the college fees rather high, but also I know that rental accommodation in the capital city will not be cheap; to say nothing of food and heating expenses! So I would very much like to arrange some temporary employment before I arrive. I was wondering if you could ask around among your friends and colleagues to see if anyone wants a house-cleaner, gardener, or nanny for their children. I know you have a wide social network in Wellington which you could canvas for me if you wouldn't mind, I'd be so grateful. I look forward to hearing from you soon. Best wishes, Juliana
