Do you have a tail? Of course not, we know. But tails are like opinions, actually, everyone has them: fishes, birds, most reptiles, and even some of our closest relatives
Since tails first evolved(进化) at least 500 million years ago. Geckos (壁虎)use them to store fat. birds use them to steer through the air, But for most mammals (哺乳动物).Yet, as you get closer to humans on the evolutionary tree, tails disappear, Gorillas(大猩猩)don' t have them, and neither do chimps(黑猩猩) or any other apes (类人猿) including us, of course, To understand why, take a look at how we walk.
walking like this gives us a huge advantage because unlike four﹣legged animals. which have to pour energy into every step they take, two legs take advantage of gravity(重力),which does some of the work for us. You see, each time we take a step, gravity pulls us forward. The end result is that when we walk, we use around 25% less energy than walking on all fours, and this way of getting around also totally eliminate (淘汰) the need for a tail.
It's said that you can still see a reminder of a time when our ancient ancestors had one. Just look at a human spine(脊椎).That's your tailbone. It's all that's the rest of our tail.
Now, babies are born with what looks like a tail, but that's not what's really going on. Most often, these tails are actually a parasitic twin(寄生虫). These types of tails usually form as a birth defect(瑕疵).
So the tail of humans has gone, it's the result of evolution millions of years Will humans be much taller, stronger or smarter in the future?
A. Nowadays, humans can walk completely upright. B. And in these situations, doctors will advise to remove the tails with no harm to the babies C. they serve one major purpose—balance. D. You can see how the last few bones are partly fused(融合) together |
Courage is the ability to be brave in different situations in our life. Here and there, now and then, everyone needs courage to do something well. Courage may make you confident of your success. If you have courage, you will not show fear in face of anything difficult or dangerous. With courage, you may look at someone in the eye who you have wronged (冤枉) and say “I am sorry”, you may keep smiling even if you are seriously ill and know you are at the end of your life.
How can we build up our courage?
·Believe you will be successful. | Take chances and know that you have your own talents. Besides, your family and friends are always there for you. |
·Exercise your courage. | It can be compared to a muscle (肌肉). The more we use courage, the greater it gets. |
·Know that giving up is not a choice. | It's much easier to give up. But it takes courage to say or do what you think is right, even when other people think you are wrong. |
·Read inspiring stories of brave people. | Abraham Lincoln is one of the people who you may think of. |

Polar bears(北极熊) are soft and lovely, but they are also very dangerous. Mark's best pal is Agee, just a big cute white polar bear! Mark is a Canadian animal trainer. He and Agee became friends when the polar bear was just about four weeks old. Now Agee is 16 years old and weighs 800 pounds. She can't live at Mark's home now, but both of them are still best friends. They always play, swim and even wrestle(摔跤) together. Agee is not only Mark's best friend, but also the world's first trained polar bear star. She has acted in some films and TV advertisements(广告) . Polar bears usually live in the freezing Arctic region(冰冷的北极地区) . Unluckily, as the weather gets warmer and warmer, there is less and less room for the polar bears to live in. And they have to find their home and have less time to find food. So these make polar bears become fewer and fewer.
Mark is a trainer from {#blank#}1{#/blank#}. He has a good friend named Agee. Agee is not a girl {#blank#}2{#/blank#}a polar bear. They became good friends when Agee was one {#blank#}3{#/blank#}old.
