查看习题详情和答案>>Emperor penguins move like cars in traffic jams to keep warm, that’s according to new research by the Alfred Wegener Institute, Helmholtz Center for Polar and Marina Research in Germany. A penguin only needs to move 2cm in any direction for its neighbor to do the same thing. These movements then flow(流动) through the whole group of penguins like a “traveling wave”.
These waves also help smaller crowds join bigger groups, keeping more and more of their friends warm. A single Antarctic “traffic jam” has thousands of penguins. Interestingly, the technology used for studying road traffic jams was used to study the penguins. This included studying time-lapse(延时) videos. Scientists also discovered that unlike on the road, these waves can be made by any penguin and in any direction.
With temperatures usually dropping below –50℃, and winds reaching speeds of up to 200km/h, these traveling waves are very important for penguins to keep warm.
These penguins can also teach us a lesson. In big groups, they learn to be orderly and patient, and to never crash into each other. These are skills we should all learn from them when we are on the road!

小题4:If a penguin is in a group, it _____.| A．needs to move orderly | B．can move as fast as it likes |
| C．will not leave others behind | D．should move as slowly as it can |
