Intermediate. Imagine scuba diving near the Florida coast and suddenly getting sucked into a huge pump of a nuclear power plant! Or writing love letters to someone every day for a year, only to see that person marry the mail carrier? The universal appeal of these real-life human-interest stories engages beginning ESL students with humor, poignancy, or astonishment, and helps them to become fluent readers. New "challenge pages" at the end of each unit feature supplemental readings related to the main story, but written at a slightly higher level. These readings help intermediate-level students make the transition from controlled to authentic written English.
