9 . Easy Ways to Build Vocabulary

It's not all that hard to build an advanced and large vocabulary. Like many things in life, it's     1    ongoing process, and the best part of the process is that there's enough room for improvement,     2    means you'll just keep getting better and better. Of course you have to work at it. You wouldn't think that a few     3    (month) of exercise in your teens would be enough     4     the rest of your life, and that's also true for building your vocabulary--you have to keep at it daily, and pretty soon you will find that you have an excellent vocabulary.

One of the     5    (effect) ways to build vocabulary is to read good books. You need to     6    (real) read at least one good book a week, preferably a classic. This isn't as hard as it     7    (sound), and it is far better than any other method because you improve your vocabulary while     8    (read) an interesting piece of literature. Another nice thing is that you learn both new words and     9    (they) use unconsciously, meaning that you will tend to use the words     10    (learn) this way in conversations almost automatically.

Litter is everywhere, doing great harm     1     the environment and life on our planet. Jeff Kirschner, who wants to build a litter-free world, started a global community named Litterati     2    (settle) this problem.

The story began with his 6-year-old daughter. One day they were going on a hike when the girl noticed a broken plastic tub (浴盆) in a river. She said, “Daddy, that doesn't go there.”That took Kirschner by surprise. He, like many adults, had become so used to seeing the rubbish     3    (throw) around them that he hadn't given it a second look.     4     his daughter said reminded him of the serious problem our planet faces.

Jeff started to take     5    (act). He created Litterati, an app that makes it fun to pick up litter. The idea is     6     (fair) simple: Spot a piece of trash, take a photo, post the photo online and then put the litter into dustbins.

    7    (see) that Jeff was keeping a record of the positive impact he was having on the planet, people worldwide started participating. Up to now, over 2,500,000 photos     8    (post) by 3,500 people from over 40 countries have found their way to Litterati's digital landfill.

Litterati is more than an app. It is highly     9    (effect) solution to a pressing issue. Wherever you live, whatever you do and     10     you are, join Litterati to make the world a cleaner and healthier place to live in.
