问题 单项选择题 A1型题

毒性反应()

A.与药物剂量无关

B.与药物的使用时间无关

C.常造成机体的生理性损害

D.大多为难以预知的反应

E.有时也与机体高敏性有关

答案

参考答案:E

解析:此题是理解判断题,考查考生对药物毒性反应产生原因的理解。毒性反应是由于用药量过大或用药时间过长所引起的严重不良反应,与药物剂量及使用时间有关,而且多数药物都有一定的毒性,过量或长期使用会损害各种系统或器官的功能。作为不良反应的一种,毒性反应是可以预知的。但有时正常剂量用药,由于个别机体对药物的高度敏感也可导致不良反应。所以该题的标准答案为E。

BEIJING, March 1 (Xinhua)-China's top economic planning body has confirmed the government will take concrete actions to develop a low-carbon economy after it promised to considerably reduce carbon emission (排放) at  last year's Copenhagen Climate Conference.

China would include the low-carbon targets in the 12th five-year plan for national economic development (2011-2015) to build an energy-saving, ecologically friendly society, the National Development and Reform Commission (NDRC) said in a report to the Standing Committee of the 11th National People's Congress (NPC).

The report said the government would launch a series of technological and financial support policies to promote the use of non-fossil, renewable energies including wind, solar, biomass, geothermal (地热) and nuclear power, aiming to increase its percentage of primary energy consumption to about 15 percent by 2020 from 9.9 percent at the end of last year.

China's installed wind power capacity (容量) reached 15 million kilowatts, with 10 million kilowatts under construction at the end of June 2009, while nuclear power under construction, installed hydro-electric power capacity and solar heating collection areas were the highest in the world, it said.

The commission was also planning to make a catalog (目录) of emissions of greenhouse gases in an effort to build a monitoring and checking system to cut carbon emissions.

The economic planner decided to control unnecessary construction and industries with surplus (多余的)production capacities, such as steel, cement and electrolytic aluminum, to promote the energy efficiency and environmental protection.

The government had drafted a plan on regional development to transfer industries in eastern areas to central and western regions.

The State Council announced in November that China would reduce the intensity of carbon dioxide emissions per unit of GDP in 2020 by 40 to 45 percent compared with the level of 2005.

D.Reducing carbon emissions per unit of GDP by 40 to 50 percent.

68.Which of the following does NOT belong to China's low-carbon measures mentioned in the text?

A.Limiting the use of nuclear power and other primary energy.

B.Setting up a system to monitor and check carbon emission.

C.Controlling unnecessary construction and industries with extra production capacities.

D.Planning to move industries from eastern areas to central and western regions.

69.If you are planning to start your own business in line with the low-carbon economy, which is the best choice?
