Entire populations of American toads(蛤蟆)breed(繁殖)within the same few days at the same time each year, usually late April or early May. The toads hop to their breeding ponds after the ground has warmed and the first hard spring rain falls. To get there, many of the toads will cross roads that cut through their habitat. It will be a grand view of hopping toads as well as a disastrous killing by cars!
The toads are “slow in moving at that time of year―it’s still cool, they’ve been inactive―and they get killed” by cars when crossing roads, said Serrao, a naturalist. An April night five years ago, when Serrao went out to a country road to watch the moving of the toads, he counted 100 toads; 95 were hit by cars.
A similar story can be told for several other species of toads, frogs, crocodiles and turtles around the world.
The world’s amphibians are reducing, and road-killing is just one factor behind it. Other better-known causes of the decline include global warming, insecticides(杀虫剂), and the loss of wetlands.
Serrao says unless these animals get help crossing the road, their local populations will disappear.
Jackson, a biologist, said one way to help amphibians survive road crossings is to construct “amphibian tunnels” beneath the road. Jackson says tunnels should be a 0.6-meter-by-0.6-meter box, open at the top, and fitted with an iron grate(铁筛)to allow enough air and light into the tunnel. In addition, fences or walls should extend out from either side of a tunnel for about 30 meters, which guide amphibians toward the tunnels.
European countries have built amphibian tunnels for decades. Jackson led a team that installed the first such tunnel in
Jackson says that there are about a hundred amphibian tunnels in the

You’re rushing to work and a man ahead of you collapses on the sidewalk. Do you stop to help? In a study of by-standers, it was found that some people avert their gaze and keep on walking rather than stop and get involved.
“There is a tendency to decide that no action is needed.” says a psychologist. “The first thoughts that pop into your mind often keep you from offering help. In order to take action, you have to work against them.” Here are some common thoughts that might prevent you from helping.
● Why should I be the one? I’m probably not the most competent(有能力的) person in this crowd. You might think someone older or with more medical knowledge should offer assistance.
● What if he doesn’t really need my help? The fear of embarrassment is powerful; no one wants to risk looking foolish in front of others.
● No one else looks concerned- this must not be a problem. We can follow the people around us, but most people tend to hold back their emotions in public.
“If you spot trouble and find yourself explaining inaction, force yourself to stop and evaluate the situation instead of walking on,” says the psychologist. “Then retry to involve other people; you don’t have to take on the entire responsibility of being helpful. Sometimes it’s just a matter of turning to the person next to you and saying, ‘It looks like we should do something.’ Or asking someone if an ambulance has been called and, if not, to call for one. Once you take action, most people will follow you.”
