| Saudi Arabia, the oil industry’s swing
producer, has become its flip-flopper. In February, it persuaded OPEC to cut its
total production quotas by lm barrels per day (bpd), to 23.5m, as a precaution
against an oil-price crash this spring. That fear has since been replaced by its
opposite. The price of West Texas crude hit $40 last week, its highest since the
eve of the first Iraq war, prompting concerns that higher oil prices could sap
the vigour of America’s recovery and compound the frailty of Europe’s. On
Monday May 10th, Ali al-Naimi, Saudi Arabia’s energy minister, called on OPEC to
raise quotas, by at least 1. 5m bpd, at its next meeting on June 3rd.

A.正确 B.错误 [单项选择]It sounds like a science fiction, but researchers say it’s a scientific fact: Microscopic organisms dubbed "killer algae" are paralyzing fish with unknown toxins and then eating away at their flesh. They might be making people sick, too.
The name given to this single-cell organism, or dinoflagellate, is Pfiesteria piscimorte- literally, "fish killer. " It was discovered at North Carolina State University in 1988, but at the same time, few scientists believed in its existence, much less in its highly unusual predatory nature. But ongoing research has led to international acknowledgment of the phenomenon and, recently, research funding. Seemingly prompted by an unknown substance secreted by fish, the aggressive creature swims into action. It sends neurotoxins into the water and air, paralyzing a fish’s nervous system, and causing it to gasp for air at the surface. Eventually the fish suffocates. The killer dinoflagellate then attaches itself to the fish and A. Scientists have solved the mystery about the fish killer. B. More studies need to be made about the fish killer. C.
