Question

According to the studies from the UN, the increase of CO₂ in the air is responsible for 85% of the temperature increase. CO₂ goes into the air when we burn fossil fuels to run our industries, cars and so on. Luckily, half of the CO₂ that we produced is taken in by plants, trees, land and the oceans. The rest gases are still large to cause worry. At the same time, we are cutting down forests that take in carbon from the air.

To solve the problem is not an easy job. Developed nations such as the USA, Germany and Australia will have to promise to cut down greenhouse gases by as much as 25-40%. Countries such as India and China that have a large population and growing industry, have to leave a smaller greenhouse gas footprint. Everybody must be active and stick to it.

1. Half of the CO₂ that we produced can be taken in by ___________.

A. plants and trees       B. land

C. the oceans             D. A, B and C

2. Why does the temperature increase?

A. People use up useful gases.

【解析】

试题分析：根据联合国研究表明空气中二氧化碳的含量增多造成温度上升。人类活动导致空气中二氧化碳不断增多。发达国家和发展中国家积极采取措施。

1.D细节理解题。 根据文中故选Luckily, half of the CO2 that we produced is taken in by plants, trees, land and the oceans.可知，幸运地是，我们产生的二氧化碳有一半被植物、树木、海洋所吸收。故选D

2.B细节理解题。根据文中the increase of CO2 in the air is responsible for 85% of the temperature increase. CO2 goes into the air when we burn fossil fuels to run our industries, cars and so on.可知空气中二氧化碳的增多造成温度上升。我们燃烧矿物燃料运转我们的工业、汽车等造成二氧化碳被排放到空气中。故选B

3.USA, Germany and Australia；Countries such as India and China 可知提到5个国家。故选C
