A. a few years ago, there was no smog at all B. today people don’t have to talk to each other in a loud voice C. we can drink water from the polluted rivers and lakes D. people are making rules in order to fight pollution (B)The giraffe is the tallest modern land animal. It can be over 5.5meters tall. Its neck alone may be 1.9 meters long. Yet the giraffe has only seven bones in its neck, the same number as in the human. Even a small bird has many more bones in its neck than in a tall giraffe. Each bone in a giraffe’s neck is very long, while the bones in a human neck are small. That makes the difference. A femalegiraffe gives birth to one baby at a time. The baby called a calf, is about1.9 meters tall at birth. By the age eight it is full-grown. The giraffe eats mostly leaves. Because it has a long neck, it can reach the leaves high up on the tree. 【查看更多】
