Any mistakes in this email? Hi Neil, Regarding the photos you sent yesterday, our technician informed it was the drive connector not the motor connector.

Are these translations right? 1. 电机装在机器的哪个位置上？请拍一张照片。 Which part of the machine does the motor installed in? Pls take a clear photo. 2. 拍一张清晰的安装孔的照片，机器已经更新换代了，老机器的接线可能跟新机器的接线不一样了。 Take a clear photo of the mounting holes, the machine has changed and the wirings maybe different from the new machine's.

today's weather Today is very cold. The weather forecast calls for snow this afternoon. Now it is cloudy. Sometimes the weather forecast is accurate, sometimes not. Maybe it will be the last snow in this winter. Spring is coming. We look forward to it. The warm weather and fresh air, children could play outside. Everything will rouse up from sleeping.

my job I’d like to talk about my current job as a purchaser in an international trade company which purchase packing machines from the domestic market and export to the overseas markets. I usually send inquiries to the suppliers and place orders, then report everything to the boss. A middle-age man who found the company 15 years ago. He is always strict with us. It’s not easy to work with him. I have to remember every details about the machines and orders, really high pressure. I don’t like to work in such tension, it makes me lose sleep and have nightmares.
