Space Pens:$34.95
Imagine a pen that works no matter what the conditions, from wet paper to writing upside down. Sounds impossible, doesn’t it? Not when you’ve got a Space Pen!
These amazing pens have a great history of being approved for use in space, since they effortlessly write in the gravity free vacuum of space, and at any angle. They can also write in extreme heat and cold temperatures(from –50℉ to 250℉), making it the pen of choice for the Everest North Face Ski Expedition(珠穆朗瑪北峰滑雪探險) in 1997. Now that you know that Space Pens are the clear choice for all your writing needs on your next adventure!
決定一件商品是否會被購買的要素是什么？1.用途；2.特點；3.性能；當然還有其價格。
本文依次介紹了以上諸要素，但最主要的還是其獨特的性能：不懼嚴寒酷暑、經得太空考驗--堪為探險時的明智選擇（the clear choice）！
明白廣告該怎么寫了吧！人無我有，人有我精，人精我特！成就一番事業是否也該如此？！
常用表達法(Useful Expressions)
嚴格地講，說明與廣告不應該屬于同一個范疇，但它們在許多地方又具有密不可分的聯系，特別是在描述該物體及闡述其特性時更是如此。所以本文將其合并在一節內容中來學習。
1. 關于物件的描述方法，可參看“描述物體（Describing Things）”一節；
2. 說明的語言應該盡量科學準確，不含糊其詞；
3. 廣告的語言應該趣味性強，通俗易懂。易于朗讀，便于記憶。
