The Amazon rainforest is the largest rainforest in the world, which plays    1    significant role in maintaining the fine balance of the Earth's ecosystem. It crosses into eight     2     (country) and covers an area of around 6 million square kilometres. The Amazon River, from which the rainforest gets     3     (it) name, supports many different ecosystems on its journey. They give this area the    4     (rich) biodiversity on the Earth. Of the 390,000 plant species known to us, more than 40,000 can     5     (find) in the Amazon. Each level of the forest forms its own little world, home to different kinds of     6     (live) things. More than 1,300 species of birds and over 400 species of mammals hide among the jungle's plant life,     7    form the forest's food chain. The Amazon rainforest is often known     8     the “lungs of the planet”. However, over the past 50 years, about 17 per cent of the rainforest    9     (disappear) due to human activities. Can we afford     10     (damage) the “lungs of the planet"?

Caught in a flood

Mary and her parents were downstairs in the living room. Mary was looking through the windows at the endless rain outside. It had been raining non-stop for three days. She had never seen a storm this bad. It was making her nervous. The wind roared the rain beat on the roof and windows. Dad was listening to a weather report on the radio, while Mum was putting their important documents and disaster supplies into a bag.

“Mum, Dad,” said Mary suddenly, “I think we should leave here right away!”

“No” said Dad. “It’s too late! The radio says the city has already been flooded.”

“We can drive our car through the floodwater! Let’s just leave! I’m really scared!” cried Mary. “We can’t do that, honey,” explained Mum, “otherwise the moving water could wash the caraway!”

Mary walked to the door. She was curious to see how much water there was outside.

“Don’t open the door!” shouted Mum and Dad at the same time. “The water may flood in!”

Dad moved the dinner table against the door, in case the floodwater forced the door open. Mum waved to Mary to sit on the sofa. “Mary, don’t worry. Everything’s going to be OK,” she said softly, trying her best to comfort Mary. Her voice was calm, but Mary could tell she was worried too.

Without saying a single word, Dad walked to the sofa, sat down and hugged his wife and daughter. The sudden silence in the house seemed to make the wind and rain more frightening outside. What could they do?

8 . Research has found that using wood for construction instead of concrete and steel can reduce emissions. But Tim Searchinger at Princeton University says many of these studies are based on the false foundation that harvesting wood is carbon neutral (碳中和). “Only a small percentage of the wood gets into a timber (木料) product, and a part of that gets into a timber product that can replace concrete and steel in a building,” he says. Efficiencies vary in different countries, but large amounts of a harvested tree are left to be divided into parts, used in short-lived products like paper or burned for energy, all of which generate emissions.

In a report for the World Resources Institute, Searchinger and his colleagues have modelled how using more wood for construction would affect emissions between 2010 and 2050, accounting for the emissions from harvesting the wood. They considered various types of forests and parts of wood going towards construction. They also factored in the emissions savings from replacing concrete and steel.

Under some circumstances, the researchers found significant emissions reductions. But each case required what they considered an unrealistically high portion of the wood going towards construction, as well as rapid growth only seen in warmer places, like Brazil. In general, they found a large increase in global demand for wood would probably lead to rising emissions for decades. Accounting for emissions in this way, the researchers reported in a related paper that increasing forest harvests between 2010 and 2050 would add emissions equal to roughly 10 percent of total annual emissions.

Ali Amiri at Aalto University in Finland says the report’s conclusions about emissions from rising demand are probably correct, but the story is different for wood we already harvest. “Boosting the efficiency of current harvests and using more wood for longer-lived purposes than paper would cut emissions,” he says. “We cannot just say we should stop using wood.”

1. What is wrong with previous researches according to Searchinger?

A．They got wrong statistics.	B．They used an incorrect concept.

2. What does paragraph 2 mainly talk about?

A．The process of the new research.	B．The background of the new study.
C．The challenge of the new research.	D．The achievements of the new study.

3. When will the emissions drop off greatly according to the new study?

A．When wood grows slowly.

B．When wood is largely used to make paper.

C．When wood is largely used in construction in countries like Brazil.

D．When wood is largely harvested in countries like Brazil.

4. What is Ali Amiri’s attitude toward the new result?

A．Favorable.

B．Doubtful.

C．Critical.

D．Objective.

9 . Begun 30 years ago, the Kubuqi desert greening project has succeeded in not only controlling the fast growth of the seventh-largest desert in China, about the size of Kuwait, but also turning about 6,000 square kilometers of the desert — one-third of it — green.

The desert lies about 800 kilometers to the west of Beijing in the Inner Mongolia autonomous region (自治区) and the greening efforts have also controlled desertification (沙漠化) in the rest of the area.

The project, which began about 30 years ago, can be looked to as an example of efforts to advance green development, in order to create harmony between humans and nature, and leave a better environment for future generations.

The success of the project, which has been praised by the UN Environment Programme as an “eco-pioneer”, sets an example for successful desertification control and ecosystem improvement based on effective government policies, supported by investment (投资) in the eco-industry and combined with the efforts of local farmers. These three aspects are key to the success of the “Kubuqi model”.

Elion, a private ecology (生态) and investment company, has invested about 38billion yuan ($5.82 billion) in the Kubuqi desert-greening project since 1988 helping to lift about 102,000 local farmers out of poverty. For example, the locals grow a drought-tolerant (耐旱) plant, Chinese licorice, which is the most used herb in traditional Chinese medicine. The plant helps enrich the desert soil, with the bacteria around the roots of the plants producing nitrogen(氮气).   Besides, Cistanche, another type of drought-tolerant herb, was introduced after the successful planting of licorice. Under the company’s guidance and with the local government’s support, the local people benefit from the   “environmental wealth”.

More companies should be encouraged to apply the “Kubuqi model” in other desert control projects in Inner Mongolia and neighboring Gansu province, where the climate conditions are similar but not quite the same, so as to further gain experience and enrich the model in practice. Showing it can be successfully applied in other areas will help promote the model worldwide.

1. What do we know about the Kubuqi greening project?

A．It increases the areas of desert.

B．It has turned all of the desert green.

C．It has achieved satisfying results.

D．It is applied all over the world.

2. Which is NOT the reason for the success of the   “Kubuqi model”?

A．Efforts of local farmers.

B．Government policies’ support.

C．Investment in the eco-industry.

D．Help from the UN Environment Programme.

3. How does the author develop paragraph 5?

A．By following the time order.

B．By giving examples.

C．By giving a definition (定义).

D．By making comparisons.

4. What is the author’s attitude towards the greening project?

A．Negative.	B．Doubtful.
C．Supportive.	D．Indifferent.
