A、电场中某点电场强度的方向，就是试验电荷在该点所受电场力的方向； the direction of the electric field intensity at A certain point in the electric field, is the direction of the electric field force on the test charge at that point

B、电场中某点电场强度的方向可由E=F/q0确定，其中q0为试验电荷的电量，q0可正、可负，F为试验电荷所受的电场力； the direction of the electric field intensity at a certain point in the electric field can be determined by E=F/q0, where q0 is the electric charge of the test charge, q0 can be positive or negative, and F is the electric field force of the test charge

C、在以点电荷为中心的球面上，由该点电荷所产生的电场强度处处相同； on a sphere centered on a point charge, the intensity of the electric field generated by that point charge is the same everywhere

D、以上说法都不正确； none of the above is true;

听力原文： New research into global warming published in the journal Science says the northern hemisphere is uniformly warmer now than at any time in the past 1,200 years, It says the present warm period in northern regions is the longest and most widespread temperature anomaly since the 9th century. Researchers have said in the past that the 20th century warming was unprecedented over the past thousand years, at least in the northern hemisphere. But critics disputed the claim, citing periods of extreme warm in certain regions during the Middle Ages. The new study sets out to tackle that criticism head on. Looking at the regional patterns of temperature for the past millennium, it finds while there have been patchy periods of warmth in the past, only in the late g0th century are regions across the hemisphere heating up simultaneously. The analysis is also statistically simpler than previous studies, avoiding the charge that mathematical quirks have generated a false picture of the climate.

In order to avoid certain charge, the analysis involves

A．cautious predictions.

B．impartial judgment.

C．careful calculation.

D．simple statistics.
