试题详情

The vast jungles of the Amazon rainforest are home to tribes (部落) mostly isolated from the outside world, whose way of life, largely unchanged for hundreds of years, is now increasingly threatened by modern civilization.

Now, scientists discover they can monitor these “uncontacted tribes” using satellites, which would allow inexpensive and safe tracking of these tribes in order to protect them from outside threats.

In order to help preserve these uncontacted Indians, researchers need accurate estimates of their populations. One way to collect this data involves flying over their villages, but such over-flights are both expensive and could fill these native peoples with fear. Another strategy involves meeting individuals on the ground, but among other risks, scientists could accidentally spread disease to members of the tribes.

Instead, scientists investigated whether satellite images could monitor uncontacted tribes. The result was inspiring. They confirmed their locations and measured the sizes of their village, houses and gardens. “We can find isolated villages with remote sensing and study them over time.” Walker told Live Science. “We can ask: Are they growing? Do they move?”

Surprisingly, based on the sizes of the houses and villages, the scientists find the population densities of these isolated villages are about 10 times greater, on average, than other villages of native Brazilian peoples. This may be due to the fact that they have to live closer together because they are not as good at clearing the forest, since they lack modern devices like chainsaws and tractors, the researchers said. The tribes may also be afraid of spreading out due to fear of being attacked by outsiders, Walker said.

The researchers now plan to focus on 29 more isolated villages to “look at their ecology— that is, distance from rivers and roads—and use this to model where else we can find more isolated villages,” Walker said.

1.Scientists don’t want to meet the Indians on the ground due to the fear that ______.

A. they can’t get accurate data

B. they could pass disease to the Indians

C. they will be attacked by the Indians

D. they will catch disease from the Indians

2.According to the passage, which of the following about the Indian tribes is NOT true?

A. They lack modern tools to cut forests.

B. Their life styles remain unchanged.

C. They live closer together for defense.

D. They are contacting the outside world.

3.What can we learn from the last paragraph?

A. More isolated tribes are yet to be discovered.

B. Scientists are able to find 29 Amazon tribes in total.

C. It’s easy for scientists to find isolated villages.

D. More roads should be built for the tribes.

4.Which of the following might be the best title for the passage?

A. The Disappearing of the Ancient Amazon Tribes.

B. Discovery of Indian Tribes in Remote Mountains.

C. The Threatening of Modern Civilization to Tribes.

D. Research of Isolated Tribes with Modern Devices.

Major causes of record fires sweeping across the Amazon rainforest this month include the dry season and human activities, according to research institutions and media reports.
The rainforest is typically wet and humid, and the frequency of fire activity usually rise each year since July — the onset of the dry season, and peaks in September and decreases in October as the rainy season approaches.
However, data from the Brazil’s National Institute for Space Research (Inpe) showed that the number of forest fires in Brazil soared by 82 percent from January to August this year from a year ago, and over half of those fires occurred in the Amazon rainforest. A total of 71,497 forest fires were registered in the country in the first eight months of 2019 , up from 39,194 in the same period in 2018, the Inpe said.
Human activities have led to the recent increase of fires, some experts have noted. The view was echoed by many, though they were divided over who actually conducted the activities. On Friday evening, Brazilian President Jair Bolsonaro pledged “zero tolerance” of environmental crimes, adding that the Armed Forces troops and resources will be mobilized from Saturday to help put out the fires.
Earlier this week, Bolsonaro blamed non-governmental organizations for increasing wildfires in the Amazon rainforest in the country’s north. His claim was refuted (反驳) by environmentalists, who argued that the surge of fires was a result of increasing deforestation and burning fueled by the governments anti-environmental policy. Alberto Setzer, an Inpe researcher, told local news site G1 that all the fires are results of human activities some accidental while others intentional.
Scientists and environmental groups are worried that the fires will aggravate climate change crisis and threaten biodiversity. The emergency has now transcended (越过) Brazil’s borders , reaching Peruvian, Paraguayan and Bolivian regions.

2.Which of the followings is not the main causes of the Amazon’s fires?
A.The dry weather. B.The intentional deforestation.
C.The natural disasters. D.Some accidental human activities.
3.What can we infer from Paragraph Three?
A.Similar to that in 2018, the frequency of fire activity will peak in September in 2019.
B.Compared with those in 2018, fires have happened more frequently in the first eight months in 2019.
C.There are more fires in 2019 than in 2018.
D.All of the big fires have happened in the Amazon rainforest.

A.Non-governmental organizations are responsible for wild fires in the Amazon rainforest.
B.The Amazon rainforest fires may be attributed to human activities.
C.We should pledge “zero tolerance” of environmental crimes.
D.The fires will influence Brazil’s bordering countries.

Rainforests have ______ over millions of years to turn into the incredibly complex environments they are today. Rainforests represent a store of living and ______ renewable natural resources that for eons, by virtue of their richness in both animal and plant species, have ______ a wealth of resources for the survival and well-being of humankind. These resources have included basic food supplies, clothing, shelter, fuel, spices, industrial raw materials, and medicine for all those who have lived in the majesty of the forest. ______, the inner dynamics of a tropical rainforest is an intricate and fragile system. Everything is so ______ that upsetting one part can lead to unknown damage or even destruction of the whole. Sadly, it has taken only a century of human intervention to destroy what nature designed to ______ forever.
The scale of human _____ on ecosystems everywhere has increased enormously in the last few decades. Since 1980 the global economy has tripled in size and the world population has increased by 30 percent. Consumption of everything on the planet has risen——at a cost to our ______. In 2001, The World Resources Institute estimated that the demand for rice, wheat, and corn is expected to grow by 40% by 2020, increasing irrigation water demands by 50% or more. They further reported that the demand for wood could double by the year 2050; ______, it is still the tropical forests of the world that supply the bulk of the world's demand for wood.
In 1950, about 15 percent of the Earth's land surface was covered by rainforest. Today, more than half has already gone up in ______. In fewer than fifty years, more than half of the world's tropical rainforests have fallen ______ to fire and the chain saw, and the rate of destruction is still accelerating. Unbelievably, more than 200,000 acres of rainforest are burned every day. That is more than 150 acres lost every minute of every day, and 78 million acres lost every year! More than 20 percent of the Amazon rainforest is already gone, and much more is severely threatened as the destruction continues. It is estimated that the Amazon alone is vanishing at a rate of 20,000 square miles a year. If nothing is done to curb this ______, the entire Amazon could well be gone within fifty years.
Massive ______ brings with it many ugly consequences-air and water pollution, soil erosion, malaria epidemics, the release of carbon dioxide into the atmosphere and the ______ of biodiversity through extinction of plants and animals. Fewer rainforests mean less rain, less oxygen for us to breathe, and an increased threat from global warming.

高三英语完形填空困难题查看答案及解析
When you think of a jungle adventure, what comes to mind? Are they gorgeous birds flying through the air or monkeys jumping through the forest? Do you think of plants? Probably not. After all, plants aren’t the most exciting living things in the world. They just sit there and absorb water and nutrients from the soil and the sun. But actually there are also some plants that eat insects and even small animals from time to time. We call these unusual things carnivorous(食肉性) plants. Although most carnivorous plants eat small insects, larger carnivorous plants in some hot and wet areas have been known to capture rats, birds, and frogs.
One carnivorous plant many people are familiar with is the Venus flytrap. Its unique “jaws” will function when flies and other small insects touch it. Once its jaws close on its victim, it produces a chemical substance that breaks down the insect and absorbs the insect’s nutrients.
There are several other examples of carnivorous plants. For example, some plants can catch insects with their leaves, which are like a tall narrow wineglass, while some trap their victims with sticky tentacles(触手). And some growing in ponds and streams absorb their victims like underwater cleaners. Carnivorous plants tend to grow in areas where the soil is very thin and lacks necessary nutrients. These plants must find other sources for the nutrients they need.
Trapping and eating insects allows these unique plants to survive. Unfortunately, human and environmental factors continue to threaten the limited environments where you can find wild carnivorous plants.
Still for many people, the thought of a plant eating an animal seems very strange. In fact, more than one person has turned the idea into a scary story or movie. Carnivorous plants don’t pose any danger to humans, though. Unless you’re the size of a tiny insect, you don’t have to worry about falling prey to a Venus flytrap.
1.What can we learn about the Venus flytrap?
A. It produces a special smell to attract insects.
B. It is the most important carnivorous plant.
C. It catches insects with its unique “jaws”.
D. It is a kind of poisonous plant.
2.Why do carnivorous plants hunt animals for food?
A. They try to reduce the harmful insects. B. They help keep the balance of nature.
C. They need some nutrients to survive. D. They enjoy the taste of animals.
3.What’s the challenge faced by carnivorous plants?
A. Trapping and eating them from human beings. B. Poorer environments to live in.
C. Threats from bigger animals. D. Limited choices of food.
4.What can be the best title for the passage?
A. Human’s influence towards insects B. Potential dangers in the jungle
C. Plants that eat living things D. Various survival skills of plants
