We need to be responsible(有责任心的)for our environment. Being a frugal consumer(节俭的消费者)is one way to help. But, what exactly does that mean?
Use it up

① ____
You do not always need to have new things. Suppose there are holes in your socks. Mend them and wear them longer. You don’t have to have the latest telephone until the old one doesn’t work anymore. Then you get a new one. Think twice before replacing something that still works.
②_________
When something you want is not on hand look for something else that you already have to take its place. Suppose you are preparing your lunch for tomorrow and want a better sandwich. However, there is not any butter in your home. Have a cheese sandwich instead so that you can use all of the cheese. With a little thought, you can make something do, instead of buy something new.
Do without
Think about all those things that you would like to have. Do you really need them? How long will you really play with that new toy? Make a list of things that you want. Delete the things that you don’t really need, so you can save a lot of resources(资源).
When can you get a new telephone according to the passage?
