Jungle Highway
① Central Brazil has been invaded （入侵） by engineers and construction workers. They have cut through the Amazon jungle to build a new road across Brazil.
② The new road is called the Trans-Amazon Highway. It links the cities of Brazil's east coast with another highway that stretches to the Pacific. The highway connects cities all over Brazil with new settlements in central Brazil.
③ Brazilians are both hopeful and anxious about the highway project. The land of northeastern Brazil is dry. It is difficult for the people to grow enough food or make enough money. They expect the new highway to provide new farmland and many jobs. They also expect new towns and cities to develop along the highway. They believe people will move from the coastal cities and help develop central Brazil.
④ The highway is a great challenge to Brazilian engineering. Huge cutting machines are used to clear away thick jungle growth. There are other challenges, too. Workers have to deal with heavy rains, biting insects, diseases and loneliness. They do not bring their families with them. They often miss their families and friends at home.
⑤ Ecologists（生态学家）are worried about problems the new highway has brought. The rainforest has only a thin layer （层）of rich soil. This layer has been protected by tall trees and fed by dead leaves and plants. But construction is destroying the forest. The trees have been cleared away to make room for the road and new settlements. Ecologists believe there will be no good farmland. Already, some areas of the jungle have turned into dry and dusty deserts.
