In recent years some extreme weather events have arisen from global warming because of human activities, with studies indicating an increasing threat from extreme weather in the future. Scientists were certain that global warming is being caused mostly by increasing concentrations of greenhouse gases and other humanactivities.

Its effects include warming global temperature, rising sea levels and expansion of deserts in the subtropics(亚热带). Warming is expected to be greater over land than over the oceans and greatest in the Arctic, with the continuing loss of glaciers, permafrost and sea ice. Other likely changes include more frequent extreme weather events including heat waves, droughts, heavy rainfall with floods, heavy snowfall and species extinction due to great change of temperature. Bad effects on humans include the threat to food security from decreasing crop yields and the loss of populated(住人的) areas because of rising sea levels.

Possible responses to global warming are reduction of emissions(排放), adaptation to its effects, building systems resilient to its effects, and possible future climate engineering. Most countries are parties to the United Nations Framework Convention on Climate Change UNFCCC), whose objective is to prevent dangerous climate change. It has adopted a range of policies designed to reduce greenhouse gas emissions and to assist in adaptation to global warming. It is agreed that future global warming should be limited to below 2.0 °C (3.6 °F) relative to the pre-industrial level.

On 12 November 2015, NASA scientists reported that human-made carbon dioxide continues to increase above levels that have not been seen in hundreds of thousands of years: currently, about half of the carbon dioxide released from the burning of fossil fuels remains in the atmosphere and is not absorbed by vegetation and the oceans.

1.What does the underlined word “resilient” mean?

A. be easily damaged 　　　　　　　　　　　 B. be able to recover easily

C. can be bent easily 　　　　　　　　　　 D. be difficult to change

2.Which of following is NOT mentioned as an effect of global warming?

A. rising sea levelsand expansion of deserts

B. more frequent extreme weather events

C. species extinction

D. increasing crop yields

3.Which of the following can be inferred from the last two paragraphs?

A. It is likely for us to deal with global warming by reducing greenhouse gas emissions, adapting to its effects and climate engineering.

B. There is no solution to too much carbon dioxide released into the atmosphere.

C. It is common that human-made carbon dioxide keeps on increasing greatly in the previous several centuries.

D. Future global warming should be limited to below 3.6 °C.

高二英语单项填空简单题查看答案及解析

In recent years many countries have been faced with the problem of how to make their workers more productive. Some experts claim the answer is to make jobs more varied. But do more varied jobs lead to greater productivity? There is evidence to suggest that while variety certainly makes the worker's life more enjoyable, it doesn't actually make him work harder. As far as increasing productivity is concerned, then, variety is not an important factor.

Other experts feel that giving the worker freedom to do his job in his own way is important.　 The problem is that this kind of freedom cannot easily be given in the modern factory with its complicated(复杂的) machinery. Thus while freedom of choice may be important, there is usually very little that can be done to create it.

Another important consideration is how much each worker contributes to the product he is making.　 In most factories the worker sees only one small part of the product. Some car factories are now experimenting with having many small production lines so that each worker contributes more to the production of the cars on his line. It would seem that not only is degree of worker contribution an important factor, but it is also one we can do something about.

To what degree does more money lead to great productivity? The workers themselves certainly think this is important. But perhaps they want more money only because the work they do is so boring. Money just lets them enjoy their spare time more. A similar argument may explain demands for shorter working hours.　 Perhaps if we succeed in making their jobs more interesting, they will neither want more money, nor will shorter working hours be so important to them.

1.According to the author, what advantage do varied jobs bring?

A. They increase productivity enormously.

B. They reduce boredom among workers.

C. They bring out the best in workers.

D. They relieve workers' difficulties.

2.What can we clearly see from the passage?

A. It’s practical to allow more freedom in a modern factory.

B. It's necessary to have a large number of workers.

C. It's important to raise workers’ sense of contribution.

D. It’s difficult to have more production lines.

3.The passage seems to suggest that ________.

A. more money leads to demands for shorter working hours

B. more money does not automatically create higher productivity

C. workers like more money better than more interesting jobs

D. workers expect to have both more money and more interesting jobs

4.What does the passage mainly discuss?

A. How to enrich workers'1ife.

B. How to make workers more productive.

C. How to shorten working hours.

D. How to decrease dullness in a factory.

Global warming is the process of earth's atmosphere heating up. Over the last 100 years, the average temperature of earth's atmosphere has gone up 1 Fahrenheit. The weather has not changed exactly the same way in every area of the planet. But scientists think that the rise in average temperature is already affecting the earth, s climate.

Many scientists now believe that global warming is caused by cutting down trees, producing more trash, and polluting the environment are some of the that the temperature has gone up. Many scientists believe that the biggest causes of global warming are new human technologies that release greenhouse gases into the atmosphere.

The greenhouse effect is not new. Certain gases in the atmosphere, like carbon dioxide, nitrous oxide and methane, prevent heat energy from escaping back into space. In the past, the climate didn’t change much because nature produced just the right amount of greenhouse gases to deal with it.

Today, most scientists are pretty sure that the rising temperature can,, t be blamed on nature. Ever since the industrial revolution in the 1700s, humans have relied on machines for daily life. And many of those machines give off a lot of greenhouse gases. An increase in the release of greenhouse gases from human activities is throwing nature off balance.

The climate is a very complicated thing, but many scientists agree that the rising atmospheric temperature has already damaged the environment. Sheets of ice, called glaciers, are melting in Antarctica and other parts of the globe. As glaciers break off and melt into the oceans, they are adding warm water to the oceans and causing the sea level to rise.

Over the past last 100 years, the sea level has risen 6-8 inches around the world. That means land along the coasts is beginning to disappear under water. Bigger and warmer oceans are also adding to other weather problems caused by pollution in the atmosphere. Some places have received more rain, others have had bigger storms and a few areas in the world have experienced unusual droughts.

1.What is mainly talked about in this passage?

A.The melting of glaciers. B.Global warming.

C.The world's weather. D.The earth's temperature.

2.What causes global warming according to scientists?

A.Human activities B.The nature itself

C.The earth's atmosphere D.New discoveries

3.From passage we can see that global warming will bring about________.

A.the pollution in the atmosphere. B.the rise of glaciers.

C.noisy pollution. D.natural disasters.
