Hacker site review.

 I went into the Hacker website thinking all the exercises would be easy, and they were not. They gave me a reminder of what keeps writing parallel. As in the example: A  tsunami hit a populated coast in Papua New Guinea, killing two thousand people and wiping out whole towns. This sentence was correct because the –ing forms killing and wiping are parallel. Another exercise that was helpful was what words are needed in sentence and what is not. For example: The man whom we encountered at the airport turned out to be a long lost friend, the word ‘whom’ can be omitted without causing problems for the reader.  Sometimes I use unnecessary words when they are not needed. Another helpful review during the exercises was the about shifts in verb tense. A person should not be changing tenses every few words in a sentence. In the sentence: Rowling, who is now one of the richest people in England, has the ability to make readers of any age remember their awkward preteen years. This sentence is correct because the verbs is and has are both present tense. Overall the Hacker website was very helpful, and I will use the knowledge I know to improve my writing.
