[单项选择]Modern science fiction movies are often known for their breathtaking special
Line effects. These effects can show us a glimpse of the future, and frequently have
tremendous dramatic force. Sometimes, however, special effects can leave the
science behind to focus only on the fiction. One of the worst offenders is a film’s
(5) depiction of explosions in outer space.
On the Earth, explosions occur in some form of matter, usually air or water.
The change in energy level in the matter creates the energy differential known as
a shock wave. The wave is what creates the characteristic "boom" of an explosion.
Since there is very little matter in outer space, the energy transfer never takes
(10) place. Consequently, there is no sound. Further, because air and water are not
perfect conduits for energy, they measurably slow the travel of the explosive
force. This allows the explosion to unfold in relatively slow motion, which<

Ulcers
Even though ulcers appear to run in families, lifestyle plays more of role than genetic factors in causing the illness, according to a report in the April 13th Journal of Internal Medicine. In particular, smoking and stress in men and the regular use of pain releasing medicines in women were linked with an increased risk of developing an ulcer.
Overall, 61% of ulcer risk appears to be due to environmental actors, such as smoking, and the remaining 39% is due to genes according to Dr. Ismo Raiha of the University of Turky and colleagues at the University of Helsinki, Finland. Some researchers had suggested that families may spread Helicobacteria pylori, the bacteria that can cause ulcers. However, the new study suggests this is unlikely, according to the report.
Raiha and colleagues studied data from more than 13,000 pairs of twins "to examine the roles of genetic and environmental factors in the origin of peptic ulcer dis

[单项选择]Text 2
Mothers Against Drunk Driving (MADD) has launched a new public awareness campaign aimed at Canadian Justice Minister Irwin Cotler. "Enough is Enough" advocates dropping the Criminal Code’s blood alcohol concentration (BAC) limit from 0.08 to 0.05 percent, to "protect innocent drivers on our roads. "MADD Canada CEO Andrew Murie thinks that lowering the BAC limit could result in a 6-to-18 percent reduction in crash deaths. But questions have been raised about the science behind that campaign.
MADD selectively cites a report published in 2002 by Robert Mann of the Mental Health Centre. Mann, in turn, had got those numbers from two separate studies whose data was selected from Sweden and Australia. The conclusions in Mann’s report seem to ignore the Swedish authors’ numerous warnings and cautions, as well as the limitations in the Australian study. First, the Australian study examined the effectiveness of breath testing, not lowered BAC levels, on fatal traffic crashes. Also, th
