Re:

• 9) Use of "it"
  10) use of "ing"
  11) use of e

Use it as a pronoun. Example:

• A: Do you know what happened to the cheese?
  B: Yes, I ate the last of it.

In the above example, it is a pronoun for cheese.

Use ing to form the present progressive or present participle. Examples:

• I enjoy swimming. Yesterday, I went swimming. I am swimming again today. I shall go swimming again tomorrow.

In English, we use e at the end of a word to indicate a long vowel sound. Examples:

• mat, mate
  rat, rate
  sat, sate
  not, note
  rot, rote
  bit, bite
  sit, site
  cut, cute
  mut, mute
