Many ESL (English as a Second Language) students in the United States enroll in   academic preparation programs and are in their late teens or early twenties. This is often a time when students are looking back on childhood in a different way. Their childhood memories and their viewpoint on those memories can be very useful for the production of wonderfully creative writing. For this project, the students began in class by closing their eyes and trying to return to their childhood years in order to bring early memories to their mind. After imagining for a few minutes, they began to tell each other what they remembered about those years and tried to describe a particular incident that stood out in their memories. That evening they wrote in their journals about the incident, embellishing   the story as much as possible. The next day, they read the story to a different partner and got feedback  . The partner's job was to: ask more questions to bring back the writer's memory; help the writer make sure that past tense verbs were used correctly, focusing on the difference between those things that were still true and needed present tense and those things that belonged specifically to the past. Two days later, students made necessary changes or additions and turned in a typed copy of their story. I then made my own comments about their work and asked them to revise their work. The third draft   produced some very good work. What did the author ask his students to write about? A) What they saw around them. B) Their predictions for the future. C) Their childhood memories. D) Their opinions of the United States.

Scientists are learning new things about Antarctica, the coldest place on Earth. For example, the Antarctic ice sheet is shrinking. A new study found that summer ice loss in parts of Antarctica was at its highest level in 1,000 years. The study showed that Antarctic ice was melting mostly from below ice shelves, where the water is warmer than the ice. Eric Rignot is an earth system expert at the University of California, Irvine. He also works for the American space agency, NASA. There he serves as senior research scientist at NASA's Jet Propulsion Laboratory, also in California. He says ice melting from below is responsible for 55 percent of the shelf loss from 2003 to 2008. That is a much higher rate than scientists thought earlier. Professor Rignot and his team used satellite observations, radar and computer models to measure features above the ice to learn what was going on below. The measurements show differences from one area to the next around the continent. The major ice shelves are called Ross, Filchner and Ronne. They make up two-thirds of Antarctica's ice shelves. But they are responsible for only 15 percent of the melting ice. The professor says even small changes, like changes in ocean flow driven by wind, can make a huge difference in the melting of the ice shelf. Sixty percent of the Earth's fresh water is held in the huge Antarctic ice sheet. Professor Rignot says the study will help experts predict how the continent reacts to warmer ocean waters and helps to cause rising sea levels around the world. The study was published in the journal Science. How did Eric Rignot and his team do the research? A) He serves as senior research scientist at NASA's Jet Propulsion Laboratory. B) They used satellite observations, radar and computer models to know the things happening below the ice. C) Small changes, like changes in ocean flow driven by wind, can make a huge difference in the melting of the ice shelf. D) They melted 55% of the Antarctica's ice to prove their theory is right.
