(34~35)          What animals are the closest to human beings? The answer is chimps. But in fact, chimps have a smaller size thanhuman beings. At most, they can only be as tall as 120 cm and as heavy as 50 kg. That is the same size as a teenager.         Although chimps are smaller in size, they are a lot faster than human beings. When they move, they use both their armsand legs. Unlike human beings, chimps’ arms are longer than their legs. Because of this, chimps are very good at climbingtrees. As for walking, chimps can do it, too. But they walk in a different way. Moreover, human beings hold up their babieswith palms, but chimps use their knuckles. Chimps’ fingers are shorter than human beings’, but they are very strong and havegreat power.        Most chimps have a shorter life than human beings. But if human beings take good care of them, they can live ten moreyears.  *close 接近的 human being 人類 chimp 黑猩猩 at most 至多 teenager 青少年 palm 手掌 knuckle 掌指關節
