The beginning of American
literature American has always been a land of beginnings. After Europeans " discovered" America in the fifteenth century, the mysterious New World became for many people a genuine hope of a new life, an escape from poverty and persecution, a chance to start again.

Long before the first colonists arrived, before Christopher Columbus, before the Northmen who found America about year 1,000, Native Americans lived here.

The Weight Experiment
Nicola Walters has been taking part in experiments in Scotland to discover why humans gain and lose weight. Being locked in a small room called a“calorimeter”（热量测量室）is one way to find out. 1. The signs above the two rooms read simply“Chamber One”and“Chamber Two”.These are the calorimeters:4m by 2m white-walled rooms where human volunteers are locked up in the name of science .Outside these rooms another sign reads“Please do not enter work in progress” and in front of the rooms advanced machinery registers every move the volunteers make.Each day,meals measured to the last gram are passed through a hole in the wall of the calorimeter to the resident volunteer. 2. Nicola Walters is one of twenty volunteers who,over the past eight months,have spent varying periods inside the calorimeter. Tall and slim,Nicola does not have a weight problem,but thought the strict diet might help with her training and fitness programme.As a self-employed community dance worker,she was able to fit the experiment in around her work .She saw an advert for volun- teers at her local gym and as she is interested in the whole area of diet and exercise,she thought she would help out. 3. The experiment on Nicola involved her spending one day on a fixed diet at home and the next in the room.This sequence was repeated four times over six weeks.She arrived at the calorimeter at8:30 am on each of the four mornings and from then on everything she ate or drank was carefully measured.Her every move was noted too,her daily exercise routine,timed to the last second. At regular intervals,after eating,she filled in forms about how hungry she felt and samples were taken for analysis. 4. The scientists help volunteers impose a kind of order on the long days they face in the room. “The first time,I only took one video and a book,but it was OK because I watched TV the rest of the time,”says Nicola. And twice a day she used the exercise bike. She pedaled（踩踏板） for half an hour,watched by researchers to make sure she didn't go too fast. 5. It seems that some foods encourage you to eat more,while others satisfy you quickly.Volun- teers are already showing that high-fat diets are less likely to make you feel full.Believing that they may now know what encourages people to overeat,the researchers are about to start testing a high-protein weight-loss diet. Volunteers are required and Nicola has signed up for further ses- slons。 Paragraph 2______ A.What does the calorimeter look like inside? B.What program was designed for the experiment? C.What is a calorimeter? D.What is the first impression? E.How do the volunteers kill the time? F.Why did Nicola join in the experiments?
