阅读下面三篇材料,从每题所给的A、B、C、D四个选项中,选出最佳选项。
A
Octopuses have three hearts. Two of them work only to move blood(血液) to their heads and help move the waste out of their bodies. The third works to send blood to the other parts of the body. When an octopus swims, the heart stops beating(跳动). Swimming makes them feel tired.
Hummingbirds Fly Backward
Hummingbirds are the only birds that can fly backward(向后). Why is that? Most birds move their wings(翅膀) upward and downward. But hummingbirds' wings move backward and forward. The birds are only 2 to 3 centimeters in size and they can move their wings about 8 to 200 times a second.
Why Can’t Elephants Jump?
Elephants are the only mammals(哺乳动物) that can’t jump. The bones in elephants’ legs are so straight that they don’t have the “spring(弹簧)” to help them jump off the ground. It’s also because they don’t have to. They are very big and always live in groups to protect(保护) themselves.
