3. To stick to a tight budget, Robert bought a more affordable LED TV instead of a fancy, expensive 3D TV.
分析：
─ 就英文的語意，如果是 “tight” budget，根本不能去買消費品如電視的，應該留下來用於吃飯求溫飽了。買電視有限的預算應該說limited budget才對。
─ 關於LED TV的錯誤觀念，此地澄清一下：市面上說的LED TV，其實只是 LED-backlit LCD TV（LED背光的LCD顯示器電視）而已，而目前的LED科技是以應用於戶外大屏幕顯示器為主（如台北小巨蛋外牆）。
─ fancy與expensive意義重疊，應刪去expensive。
─ 修改後成為：Robert could only afford an LED TV instead of a fancy 3D TV due to a limited budget.
5. The airport was closed because of the snowstorm, and our departure for Paris had to be delayed until the following day.
分析：
─ departure for Paris並非常見搭配語（Google的 “departure for城市” 模式都只有幾十筆資料），用flight to Paris比較常見。但這題的考點是departure，所以應把to Paris拿掉。
─ had to be delayed累贅，只要說was delayed就可以了。
─ 修改後成為：The airport was closed because of the snowstorm, and our departure was delayed until the following day.
