food． and． shelter to creatures living in and around the coral． Turtles, sharks, sea horses, and crabs are among its many inhabitants．

Helping Humans

While the reef is important to ocean life, it helps humans, too． People rely on the reef for both food and jobs． It also provides medicine used to treat disease． Each year, the Great Barrier Reef contributes about $ 975 million to the economy through tourism and fishing．

Stressed Out

Is it surprising, then, that the Great Barrier Reef is under too much stress? Fishing nets and ships break off sections and damage the reef． Air and water pollution are also doing harm． At the same time, warmer sea temperatures have caused coral bleaching（漂白） on half of the reef． The high temperatures cause the coral to turn white, often killing it．

Reef Rescue

In an effort to help save the reef, the government has limited fishing to two thirds of it． That plan increases the number of "green zones．”Those are areas that are off -limits to fishermen and boats． However, tourists and researchers can still visit them． Many fishermen are upset about the plan because they rely on the reef for jobs． The Australian government says that its plan will help keep the reef safe from some threats． "It is very important that we give B reef proper protection for the future," said one government official． The reef is Australia' s greatest natural treasure．

Ulrich's friend Anne was missing at school． His mother said that perhaps she had gone into hiding． That was the hope anyway-that the family had left on their own and had not been sent on one of the prison trains to Germany or Poland． So many people in his city had disappeared since the Nazis came to Amsterdam in 1940． "It's not our home anymore," Ulrich thought． The streets, once full of busy shoppers, were now filled with tanks and-soldiers． ．

Who were they? Who would betray（背叛） their friends and let their neighbors be captured? Ulrich remembered his friend Anne; her father had a small business right down the road from his house． Her sister, Margot, was in the upper school, where Ulrich's sister was in her class．

When he walked to or from school, Ulrich studied the faces of the people on the street．Some looked concerned and cast their eyes downward as they walked, try ring not to be noticed．His own parents had that look,
