PROBLEM: Article: A small, white envelope has peeked through the branches of our Christmas tree for the past 10 years. It has no name, no identification, no inscription . My husband Mike hated Christmas. He hated the overspending and the crazy running around at the last minute for the gifts given in desperation because you couldn't think of anything else. So one year I searched for something special to give Mike. The inspiration came in an unusual way. Our son Kevin was 12 and was on the school wrestling team. Shortly before Christmas, there was a non-league match against a team of poor kids. They were dressed in ragged sneakers, and presented a sharp contrast to our boys in their golden uniforms and sparkling new wrestling shoes. As the match began, I was alarmed to see that the other team was wrestling without helmets . Their team obviously could not afford them. We beat them hands down . Mike shook his head sadly. "I wish just one of them could have won," he said. Mike loved kids and enjoyed coaching football and baseball. That's when the idea for his present came. That afternoon, I went to a sports store and bought a load of wrestling headgear and shoes. I sent them anonymously to the poor team. On Christmas Eve, I placed a small, white envelope on the tree, the note inside telling Mike what I had done and that this was his gift from me. Mike's smile was the brightest thing about Christmas that year. In the years that followed, I sent a group of mentally handicapped youngsters to a hockey game, and a check to a pair of elderly brothers whose home had burned to the ground the week before Christmas. The white envelope became the highlight of Christmas. Mike died last year, but on Christmas Eve I still placed an envelope on the tree. The next morning it was joined by three more. Each of our three children had placed a white envelope on the tree for their dad. Mike's spirit, like the Christmas spirit, will always be with us. By Nancy W. Gavin

PROBLEM: Article: The wombat is in trouble. Some are dying in bushfires, or being shot by farmers. Others are scratching themselves to death because of a mite infection. Only 115 of one species - the northern hairy-nosed wombat - remain alive in the wild. Wombats are endemic to Australia. They are found nowhere else. A wombat looks like an overgrown, stocky guinea pig, covered with thick grey fur and with a wide, flat, broad forehead. Fully-grown adults are about a meter long and about half a meter tall. They weigh about 40kg. But while their looks are pretty straightforward, people throughout history have found it less easy to understand their behavior. The Aborigines seem to have mixed feelings about them, According to one story, the wombat once said he was more powerful than the sun. After a competition, however, the wombat lost, and so today hides from shame, deep down in a hole. But another Aboriginal story tells of how wise the wombat can be. He comforts the other animals in the forest, after their friend, a cockatoo, has died, explaining to them all about forest spirits. Wombats are strong diggers, with very powerful front legs and sharp claws, usually used to dig winding holes in the ground for their homes. Yet despite their strong appearance, these animals are struggling to survive. Many have been suffering a lot from a foreign mite, from foreign foxes, introduced for hunting by the early English settlers of Australia. Because of scratching, scars form over the wombats' eyes and ears, and infections occur, finally causing their death. Its population is so small that the group is becoming inbred . Competition with cattle and sheep for grass to eat, drought, bushfires, as well as dingo and feral dog attacks have all whittled away wombat numbers. But fortunately, a group of committed volunteers and scientists, working with the local government, has now put up fences to protect the wombats from meat-eating animals, made holes for extra shelter, and is working with zoos to create developing programs. These conservationists are well aware they have little time left.
Question: According to the passage, wombats _ .
Options: (A) look like big cats. (B) are similar to foxes in size. (C) give people a sense of weakness. (D) are good at digging holes in the ground.

SOLUTION: D

PROBLEM: Article: June 5 is World Environment Day. This makes us pay more attention to our environment and the need to protect it. When Wang Boxuan, a Beijing high schoolboy, uses up his exercise books, he does not throw them away. Each one is stored at his school with hundreds of exercise books given by other students. Then they are sold to a Beijing paper making factory. The paper is recycled and used again by students and teachers in the school. At the same time, the money made from the sales goes towards schools in Inner Mongolia for planting trees and grass. This place is one of the sources of the sandstorms that often attack Beijing during springtime. Wang's school is one of the schools in the capital that take part in the "Green Promise" --environmental protection activity. So far, nearly 210,000 students have taken part in the activity, collecting more than 87 tons of waste paper. Students are eager to help make the capital a more pleasant place.
Question: What do Wang Boxuan and his schoolmates do with the waste exercise books?
Options: (A) Throw them away. (B) Store and sell them. (C) Cut them into pieces. (D) Give them to the students in Inner Mongolia.
