【题目】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.

【题目】Volunteering

Just like the animals we shelter, people are very special to us. The Animal Shelter of Sacramento County has 300 active volunteers and always wants to add more. If you have a few hours each week and a love for dogs and cats, we at the shelter welcome your coming.

【题目】C

The production of coffee beans is a huge, profitable business, but, unfortunately, full-sun production is taking over the industry and bringing about a lot of damage. The change in how coffee is grown from shade-grown production to full-sun production endangers the very existence of, certain animals and birds, and even disturbs the world’s ecological balance.

On a local level, the damage of the forest required by full-sun fields affects the area’s birds and animals. The shade of the forest trees provides a home for birds and other special(物种) that depend on the trees’ flowers and fruits. Full-sun coffee growers destroy this forest home. As a result, many special are quickly dying out.

On a more global level, the destruction of the rainforest for full-sun coffee fields also threatens(威胁)human life. Medical research often makes use of the forests' plant and animal life, and the destruction of such species could prevent researchers from finding cures for certain diseases. In addition, new coffee-growing techniques are poisoning the water locally, and eventually the world's groundwater.

Both locally and globally, the continued spread of full-sun coffee plantations (种植园)could mean the destruction of the rainforest ecology. The loss of shade trees is already causing a slight change in the world's climate, and studies show that loss of oxygen-giving trees also leads to air pollution and global warming. Moreover, the new growing techniques are contributing to acidic(酸性的) soil conditions.

It is obvious that the way much coffee is grown affects many aspects many aspects of life, from the local environment to the global ecology. But consumers do have a choice. They can purchase shade-grown coffee whenever possible, although at a higher cost. The future health of the planet and mankind is surely worth more than an inexpensive cup of coffee.

1】【1What can we learn about full-sun coffee production from Paragraph 4?

A. It limits the spread of new growing techniques.

B. It leads to air pollution and global warming.

C. It slows down the loss of shade trees.

D. It improves local soil conditions.

3】【3Where does this text probably come from ?
