高三英语单项填空简单题查看答案及解析

A baby born in India has been declared the world's seven billionth person by child rights group Plan International. Baby Nargis was born at 07:25 local time (01:55GMT) in Mall village in India's Uttar Pradesh state. Plan International says Nargis has been chosen symbolically as it is not possible to know where exactly the seven billionth baby is born. In addition to baby Nargis in India, Bangladesh, the Philippines and Cambodia have all identified seven billionth babies. The United Nations estimated that on Monday 31 October, the world's population would reach seven billion.

Populations are growing faster than economies in many poor countries in Africa and some in Asia. At the same time, low birth rates in Japan and many European nations have raised concerns about labor shortages.

Population experts at the United Nations estimated that the world reached six billion in October 1999. They predict nine billion by 2050 and ten billion by the end of the century. China's population of one and a third billion is currently the world's largest. India is second at 1.2 billion. But India is expected to pass China and reach one and a half billion people around 2025.

India will also have one of the world's youngest populations. Economists say this is a chance for a so-called demographic dividend. India could gain from the skills of young people in a growing economy at a time when other countries have aging populations. But economists say current rates of growth, although high, may not create enough jobs. Also, the public education system is failing to meet demand and schooling is often of poor quality. Another concern is health care. Nearly half of India's children under the age of five are malnourished(营养不良).

Michal Rutkowski, the director of human development in South Asia at the World Bank, says reaching seven billion people in the world is a good time for a call to action. He says, “I think the bottom line of the story is that the public policy needs to become really, really serious about sex equality and about access to services—to fight against malnutrition, and to provide for access to health services, water and schooling.”

1.What is true about the world's seven billionth person?

A. Baby Nargis is not the only child chosen as the seven billionth baby.

B. Baby Nargis has been chosen carefully so it is exactly the seven billionth baby.

C. Three countries have all declared Baby Nargis as the seven billi011th baby.

D. The United Nations declared Baby Nargis as the world's seven billionth person.

2.Which of the following problems do many European countries worry about?

A. Labor shortage.                B. Poor health care.

C. Not enough jobs.            D. Schooling of poor quality.

3.According to population experts, how long will it take for population to grow from six billion to nine billion?

A. About 12 years.    B. About 40 years.   C. About 50 years.   D. About 110 years.

4.What does the underlined phrase “demographic dividend” in the fourth paragraph refer to?

A. Possibility of lower birth rate.

B. Benefit gained by working young people.

C. Chances for more employment.

D. Disadvantages caused by aging population.

5.Which of the following public policies does Michal Rutkowski call on?

A. To encourage late marriage.       B. To reduce world's population.

C. To gain economic equality.             D. To improve health and education.

China’s Scariest Outdoor Attractions

As the world’s most populous nation with the world’s second-biggest economy, China is finding new and increasingly adventurous ways to attract and entertain tourists.

Fuxi Mountain, Henan

Guinness World Records receives 2,000 applications from China a year -- more than any other country. And the latest potential record-breaker is the 3,000-ton glass-and-steel skywalk at Fuxi Mountain in Henan province, central China. Visitors who dare walk on this U-shaped bridge can look straight through the glass to the valley floor about 360 meters below. The new bridge extends 30 meters beyond the cliff edge, trumping other U-shaped wonders such as Arizona’s Grand Canyon Skywalk over the epic US gorge.

Shilinxia, Beijing

32.8 meters over the edge of a 396-meter valley, the Shilinxia Viewing Platform stretches a whole 11 meters farther than Grand Canyon Skywalk. It’s constructed with titanium alloy, the material used in airplanes and space shuttles, so it can apparently hold a maximum load of 150 tons and 2,000 people. It’s a hefty 1.5-hour hike from the valley floor to the platform. Or taking the cable car up is an option.

East Taihang, Hebei

The glass walkway at the East Taihang Scenic Area in northern Hebei Province gained popularity last year when video emerged showing a terrified tour guide falling to his hands and knees as the glass apparently started cracking under his weight. Shattered glass fragments were placed underneath solid panels to make the walkway look and sound as though it’s cracking when trodden upon. While the unique walkway of Taihang Mountain is therefore safe to traverse, tourists were quick to point out that at 1,180 meters above sea level, it could still induce thrill.

1.To arrive at the platform in Shilinxia, you can　　　　　　 .

A.walk B.take cars

C.take cable cars D.both A and C

2.Which of the following attractions is likely to break the world record?

A.Grand Canyon Skywalk

B.Walkway at East Taihang

C.U-shaped bridge at Fuxi Mountain

D.Viewing platform at Shilinxia

3.What do we know about the tourist attractions mentioned in the passage?

A.Travelers won’t feel frightened since the glass walkway at Taihang isn’t cracking.

B.Both attractions at Fuxi Mountain and Shilinxia extend farther than Grand Canyon skywalk.

C.The viewing platform at Shilinxia can hold more than 2000 people.

D.The material used in airplanes is applied to the glass walkway at East Taihang.

As the world’s population grows, farmers will need to produce more and more food. And large farms are increasingly using precision farming to increase yields (产量), reduce waste, and reduce the economic and security risks that inevitably accompany agricultural uncertainty.

Traditional farming relies on managing entire fields—making decisions related to planting, harvesting, irrigating, and applying pesticides and fertilizer (农药和化肥)—based on regional conditions and historical data. Precision farming, by contrast, combines sensors, robots, GPS, mapping tools and data-analytics software to customize（量身定制）the care that plants receive without increasing labor. Robot-mounted sensors and camera-equipped drones (无人机) wirelessly send images and data on individual plants to a computer, which looks for signs of health and stress. Farmers receive the feedback in real time and then deliver water, pesticide or fertilizer in adjusted doses（剂量）to only the areas that need it. The technology can also help farmers decide when to plant and harvest crops.

As a result, precision farming can improve time management, reduce water and chemical use, and produce healthier crops and higher yields—all of which benefit farmers’ bottom lines and conserve resources while reducing chemical runoff.

Many small businesses are developing new software, sensors, and other tools for precision farming, as are large companies such as Monsanto, John Deere, Bayer, Dow and DuPont. The U.S. Department of Agriculture, NASA and the National Oceanic and Atmospheric Administration all support precision farming, and many colleges now offer course work on the topic.

In a related development, seed producers are applying technology to improve plant characteristics. By following individual plants over time and analyzing which ones flourish in different conditions, companies can relate the plants’ response to their environments with their genomics (基因组学). That information, in turn, allows the companies to produce seed varieties that will grow well in specific soil and weather conditions. This advanced technology may also help to improve crop nutrition.

Farmers do not universally welcome precision agriculture for various reasons, such as high equipment costs and lack of access to the Internet. The technology may bring great challenges to experienced farmers who are not good at computers. And large systems will also be beyond the reach of many small farming operations in developing nations. But less expensive, simpler systems could potentially be applied. For others, though, cost savings in the long run may reduce the financial concerns. And however reticent some farmers may be to adopt new technology, the next generation of farmers are likely to warm to the approach.

1.Precision farming differs from traditional farming partly because it ________.

A. guarantees high yields with more labor

B. relies on regional conditions and historical data

C. offers plenty of water, pesticides and fertilizer

D. provides real time information about target crops

2.About precision farming, we can learn that________.

A. the government holds a cautious attitude

B. it draws positive responses from businesses

C. seed producers have already made huge profits

D. large systems will soon be built in developing nations

3.The underlined word “reticent” in the last paragraph probably means ________.

A. disappointed　　 B. confused

C. unwilling　　 D. shocked

4.What is the best title for the passage?

A. Precision Farming Increases Crop Yields

B. More Challenges Faced by Modern Farmers

C. Development of Farming Systems in the U.S.

D. Traditional Farming is Gradually Disappearing

The World Wildlife Fund (WWF) says more than half of the world’s wildlife population has been lost, which the conservation group says has placed the health of the planet at risk.

The WWF recently released its 10th Flagship Living Planet Report. The group warns the condition of the world's animals is worse than its earlier reports showed, indicating worldwide action is needed.

The WWF is worried about the loss of and damage to Earth’s environment. The report provides information about more than 10,000 animal populations from 1970 to 2010. These populations are called “vertebrate species,” or animals with backbones — like fish, birds, mammals, amphibians and reptiles. The report shows these populations have dropped by 52 percent in just 40 years. It warns freshwater species have fallen by 76 percent, which is almost twice the loss of land and ocean species. Most of these losses are in the tropics, with the biggest drop in Latin America.

Marco Lambertini, the WWF’s International Director-General said, “This is about losing natural habitats. This is about converting forests, grasslands, and wetlands into agriculture mainly, and it is about unsustainable use of wildlife. Illegal hunting has been actually increasing over the last 10 years, which definitely a driving force for extinction, particularly of large species.”

The report also notes what it calls the world’s “Ecological Footprint”, that is, the effect of human activities on the planet. Mr. Lambertini says there has been an increase in carbon dioxide gases and the pouring of nitrogen into oceans and rivers from fertilizers used in agriculture, which certainly cannot continue.

“We are consuming on average every year about the equivalent of about 1.5, one and a half times the resources available to the planet. That means we are cutting trees more quickly than they can be restored. We are fishing the oceans more quickly than fishing stocks can reproduce, and we are emitting in the atmosphere more CO2 than the natural systems can actually absorb, which is clearly not sustainable.”

Mr. Lambertini warns climate change affects almost everyone on the planet and that whole species may disappear if the world does not reduce the effects of humans on the climate.

1.According to the passage, what kind of species faces the biggest drop in population?

A. Land and ocean species.

B. Animals with backbones.

C. Freshwater species in Latin America.

D. Freshwater species in the tropics.

2.All the following can contribute to the loss of world’s wildlife population EXCEPT ________.

A. turning wildlife habitats into agriculture land.

B. making sustainable use of wildlife.

C. hunting illegally.

D. emitting CO2 gases and pouring nitrogen.

3.Which does the underlined word “converting” in paragraph 4 mean?

A. Conserving.　　　 B. Conveying.

C. Exchanging.　　　 D. Transforming.

4.It can be inferred from the passage that _______.

A. Marco is much concerned about human’s current behaviors towards wildlife.

B. what the planet provides now can satisfy human’s sustainable development.

C. more than half of the world’s wildlife population has been lost.

D. if humans reduce the effects on the climate, the whole species will not disappear.
