　　[單選題]A world like no other--perhaps this is the best way to describe the world of the rainforest. No rainforest is the same-yet most rainforests can be found in the small land area 22. 5 degrees north and 22. 5 degrees south of the Equator(赤道). You can find rainforests in South America and Indonesia. Other rainforests exist further from the Equator, in Thailand and Sri Lanka.

　　Rainforests have a great role to play in supporting the world. They are home to a rich variety of plants, birds and animals. Can you believe that 480 varieties of trees may be found in just one hectare (公頃) of rainforest? These forests have around 50% of all the plants, birds and animals on Earth.

　　Rainforests have their own perfect way for living. The tall trees make a huge umbrella of branches and leaves which protect themselves, smaller plants, and the forest animals from heavy rain,dry heat from the sun and strong winds. Rainforest trees grow in such a way that their leaves and branches, although close together, never actually touch those of another tree. Scientists think this is a way to prevent the spread of any tree diseases and make life more difficult for leaf-eating insects (昆蟲). To live in the forest, animals must climb, jump, or ly across the branches and trees.The ground floor of the forest is not all leaaves and bushes, like in films, but is actually fairly clear. It is where leaves become food for the trees and other forest life.

　　Rainforests around the world are disappearing at a high speed. A few thousand years ago, rainforests covered as much as 12% of the land surface on Earth, but today this has fallen to less than 5.3%. We hope that the world governments work together with scientists to use their power and knowledge to keep the rainforests for our existence.

Why are rainforests important to the world?

　　A、They can provide food for different kinds of insects.

　　B、They can lower the temperature around the Equator.

　　C、They are home to various kinds of plants and animals.

　　D、They produce the best wood for house building.

　　[單選題]About 35%of all high school graduates in America continue their education in an institution of higher learning.The word college is used to refer to either a college or a university.These institutions offer four-year programs that lead to a Bachelor of Arts(B.A.)or Bachelor Science(B.S.)degree.Some students attend a junior college(providing only a two-year program)for one to two years before entering a four-year college as a sophomore(二年級生)or junior(三年級生).

　　It is generally easier to be accepted at a state university than at a private one.Most private schools require strict entrance examinations and a high grade point average(GPA),as well as specific college prep classes in high school.Private schools cost considerably more than state colleges and famous private schools are very expensive.Poorer students can sometimes attend,however,by earning scholarships.Some college graduates go on to earn advanced masters or doctoral degrees in grad(graduate)school.Occupations in certain fields such as law or medicine require such advanced studies.
