Some oil companies plan to get rid of some of the pollution they produce by pumping it into rocks deep inside the Earth, where they say it will stay for thousands of years. Other people, though, aren’ t so sure this is advisable; environmental groups say that putting this pollution back into the Earth is a had idea.
When oil burns, It doesn’ t just produce heat: it also produces carbon dioxide. Carbon dioxide is a natural part of the air, but because people bum so much oil, there’ s too much carbon dioxide in the air. This extra carbon dioxide is pollution; some scientific studies show that carbon dioxide is one of the" greenhouse gases" that is causing the Earth’s temperature to rise.
Environmentalists say that the oil companies’ plans may not work. The oil companies say they are making sure that the gas will never escape, but environmentalists wonder how the oil companies can be so sure that the gas won’ t seep into

Lately a lot about the affects of smoking and second-hand smoke has been reported almost weekly in the news and it’s getting very good coverage (报道范围). But we still have parents smoking in front of new-born babies and all the way through their kids lives.
For me personally, my mother and all my grandparents smoked. So no matter where I went I would inhale(吸入肺部) it. For the past year I’ve been trying to avoid my own MOTHER when she starts smoking...I feel angry because I’ve realized how much she is damaging everyone else’s health in the house, especially her grandkids.
Now this is happening all over the world. What are parents thinking They are ignoring the warning signs. Are they just to be selfish and don’t care about their kids’ health and other people’s Why should I move out of the area because of their bad habit Shouldn’t they have to go outside the room and do it

A. limited
B. encouraged

D. permitted
