Online Movie Rentals

It is generally accepted that the best way to learn a language is to totally involve yourself in its culture by living in the country where it is spoken.   71   Fortunately, many aspects of a country’s culture have made their way to our lives in the form of various media and entertainment outlets. Not only do they allow a peek at life, but they make excellent study material for learning the language.

What to increase your language skills and enjoy some entertainment at the same time? Tired of going down to the video rental store to rent movies?   72 

Most companies require customers to operate on the following model:

●Select and sign up for a payment program online, which will determine how many movies you can rent and hold at any one time.

●  73  You can look up movies by title, actor or director. Then movies will be sent to you within 1~3 days, and shipping is covered by the company.

●Watch the movies, often with no late fees.

●  74 

●Check these sites for specific, up – to – date details.

Once you receive the movies, how can you improve your language skills with them? Well, just sitting in front of the TV with a drink in one hand isn’t a bad way to relax, but you won’t learn much. While seeing a movie you should take notes of new expressions. Write them down and look them up in a good English – English dictionary to understand their possible meanings.   75  If you don’t’ know how to use words, learning vocabulary will lose all meaning.

A.Return the movies in a prepaid return envelope.

B.If you haven’t finished on time, you can delay returning.

C.Now, more and more companies are offering customers the chance to rent movies online.

D.Then, think of some sample sentences for each word. E.Choose the movie you want to watch, generally 1~3 at a time.

F.Watch movies as long as you have nothing to do.

G.While many find packing up and moving to a country is not a practical option.
