People who live in heavily industrialized areas do not get as much sunlight as they should. Dust【1】over a city at altitudes (海拔) of between 4,000 and 8,000 feet cuts out between 20 and 50 percent of the sunlight and up to 90 percent of the ultraviolet light (紫外线). But dust is not the only thing to【2】about. When fuels are burned, whether in a factory, or in a home, or in the engine of a car, CO

is given off.

Did you know, for example, that a hundred cars produce on【7】a third of a ton of CO, as well as many other【8】substances every day?
Now, more and more people are realizing the importance of clean air. Schools are now teaching about the pollution problems. Scientists and engineers are trying to【9】new engines for cars.

M. regulation N. generously O. worry
【4】
选项
答案
I
解析
此处应为名词,作raising的宾语。在本句中,raising the…是keeping warms in的结果,也就是说,二氧化碳阻挡了地球热量的散发,造成的结果就是使地球的温度上升,可见本题答案为temperature。
