I wouldn’t if

I, Me, Myself, and My 修辞手法 metaphor,analogy,allusion Maybe a good analogy here is bar codes and serial numbers. Take an iPod in a store. On the packaging will be a bar code. This tells the store what the product is, so when it is scanned, the system knows exactly what the product is and what it costs. It might even be able to know what color it is or where it was kept in the store. All iPod of this same type has the exact same barcode on them. The iPod will also have a serial number on it which is absolutely unique to any other iPod (or any other device) in the world. The serial number doesn’t know the price. It could, but for the store, this wouldn’t be a very efficient way to store and use that data. Much easier to use the barcode, so that for example, if the price changed, you could just change the price for that bar code and not every individual serial number in your system. This is much like ID’s and Classes. Information that is reusable should be kept in a class and information that is totally unique should be kept in an ID.

  3. I will make it happen.
  4. You should let it happen.
    Below, the word ‘he’ functions as a subject, and so the verb agrees in number with its subject:
