Weed your words: Clear the clutter

We are often told to write the way we speak. But sometimes when we speak, we use more words than we need. While we can get away with redundant and long-winded expressions in speech, we should be careful to avoid this fault in writing. See if you can weed out the unnecessary words in the sentences below.
