Dear deer

You are required to give a presentation for the company and will use a kind of equipment you are not familiar with. Write a letter and ask one of your colleges for help

Write a letter to your college. In your letter:

Write when and where the presentation will be

Give details how you will use the equipment

Be specific how he or she can help

解析：
這是一封給同事的求助信，可以確定這是一封非正式的信件，稱謂、文後落款、信件語氣都較為輕鬆隨意。
題目列出了三個問題，注意每個問題的關鍵字：presentation的時間和地點，關於如何使用設備的細節，同事可以如何幫助的細節。讀題的時候記得劃關鍵字，如果漏掉某個資訊，TA會扣分。

參考範文：

Dear John,

I am writing to ask for your help about how to use the projector in Room 202.(開頭I am writing to……直接介紹寫信目的)

As I have mentioned above，the presentation will be given on next Friday morning in Room 202 since it is the only room that can hold/seat(容納) all the staff. (回答題目問題，並適當補充細節，使文章看起來生動合理)This is where I get trapped---I have no idea about how to use the projector(引入下一個問題，過渡自然)

I have prepared two charts，one for the sales volume in last month and another for this month. To better illustrate the data involved，I have to project these two charts onto the same screen and then skip to the next page where the detailed comparison is listed.

Therefore(承接上面的問題描述，提出需要的説明)，I would appreciate it if you can tell me how to project my pictures clearly and how to switch back and forth between pages swiftly. Besides，I would like to know how to adjust my speech to better suit my audience since you are quite good at giving presentation.(可以提出額外的要求，讓信件更加生動)

I do hope you will be able to send me a favorable reply and your warmhearted help will be greatly appreciated . (文末提出感謝)

Yours sincerely,

Mary
