Part II   Reading Comprehension    (35 minutes )
Passage One
Questions 11 to 15 are based on the following passage .
      Low-level slash-and-burn farming doesn’t harm rainforest . On the contrary , it helps farmers
and improves forest soils . This is the unorthodox view of a German soil scientist who has shown that
burnt clearings in the Amazon , dating back more than 1,000 years , helped create patches of rich ,
fertile soil that farmers still benefit form today .

     Most rainforest soils are thin and poor because they lack minerals and because the heat and heavy
rainfall destroy most organic matter in the soils within four years of it reaching the forest floor .
This means topsoil contains few of the ingredients needed for long-term successful farming .

     But Bruno Glaser , a soil scientist of the University of Bayreuth , has studied unexpected patches
of fertile soils in the central Amazon .These soils contain lots of organic matter .

     Glaser has shown that most of this fertile organic matter comes from “black carbon” –the organic
particles from camp fires and charred (烧成炭的) wood left over from thousands of years of slash –and-burn
farming . “The soils , known as Terra Preta , contained up to 70 times more black carbon than surrounding
soils,” says Glaser .

       Unburnt vegetation rots quickly , but black carbon persists in the soil for many centuries .
Radiocarbon dating shows that the charred wood in Terra Preta soils is typically more than 1,000 years
old .

      “Slash-and –burn farming can be good for soils provided it doesn’t completely burn all the vegetation,
and leaves behind charred wood ,” says Glaser . “It can be better than manure (粪肥).”Burning the forest
just once can leave behind enough black carbon to keep the soil fertile for thousands of years . And rainforests
easily regrow after small-scale clearing .Contrary to the conventional view that human activities damage the
environment , Glaser says: “Black carbon combined with human wastes is responsible for the richness of Terra
Preta soils .”

       Terra Preta soils turn up in large patches all over the Amazon , where they are highly prized by farmers.
All the patches fall within 500 square kilometers in the central Amazon .Glaser says the widespread presence of
pottery (陶器) confirms the soil’s human origins .

      The findings add 慰ght to the theory that large areas of the Amazon have recovered so well from past
periods of agricultural use that the regrowth has been mistaken by generations of biologists for “virgin”
forest .

       During the past decade , researchers have discovered hundreds of large earth works deep in the jungle .
The are up to 20 meters high and cover up to a square kilometer .Glaser claims that these earth works ,built
between AD 400 and 1400 , were at the heart of urban civilizations .Now it seems the richness of the Terra
Preta soils may explain how such civilization managed to feed themselves .
 
11. We learn from the passage that the traditional view of slash-and-burn farming is that _______.
A) it does no harm to the topsoil of the rainforest
B) it destroys rainforest soils
C) it helps improve rainforest soils
D) it diminishes the organic matter in rainforest soils
 
12. Most rainforest soils are thin and poor because _______.
A) the composition of the topsoil is rather unstable
B) black carbon is washed away by heavy rains
C) organic matter is quickly lost due to heat and rain
D) long-term farming has exhausted the ingredients essential to plant growth
 
13. Glaser made his discovery by ______.
   A) studying patches of fertile soils in the central Amazon
   B) examining pottery left over by ancient civilizations
   C) test-burning patches of trees in the central Amazon
   D) radiocarbon- dating ingredients contained in forest soils
 
14. What does Glaser say about the regrowth of rain forests ?
   A) They take centuries to regrow after being burnt
   B) They cannot recover unless the vegetation is burnt completely
   C) Their regrowth will be hampered by human habitation
   D) They can recover easily after slash-and-burn farming
 
15. From the passage it can be inferred that ________.
   A) human activites will do grave damage to rainforests
   B) Amazon rainforest soils used to be the richest in the world
   C) farming is responsible for the destruction of the Amazon rainforests
   D) there once existed an urban civilization in the Amazon rainforests
