属于先天性行为的是
A、老鼠走迷宫 B、黑猩猩模仿人
D、猴子学人走路 D、母鸡哺育雏鸡
答案：D
题目分析：动物的行为受神经系统和激素调节，受体内的遗传物质控制。包括先天性行为和后天性学习行为两种，先天性行为即是本能行为，是生来就具有的，如蜜蜂采蜜，母鸡哺育雏鸡、野鸭迁徙和蜘蛛织网等；后天性学习行为是在出生后在生活过程中逐渐形成的，适应复杂多变的环境，如鹦鹉学舌、黑猩猩摘香蕉、老鼠走迷宫、黑猩猩模仿人、猴子学人走路等。故选项C符合题意。

根据短文内容，从下框的A-F选项中选出能概括每一段主题的最佳选项。 选项中有一项为多余选项。
Sometimes you’ll hear people say that you can’t love others until you love yourself. Sometimes you’ll hear people say that you can’t expect someone else to love you until you love yourself. Either way, you’ve got to love yourself first and this can be tricky. Sure we all know that we’re the apple of our parents’ eyes, and that our Grandmas think we’re great talents and our Uncle Roberts think that we will go to the Olympics, but sometimes it’s a lot harder to think such nice thoughts about ourselves. If you find that believing in yourself is a challenge, it is time you built a positive self-image and learn to love yourself.
you act, the way you talk and the way you think. Interestingly, our self-images are often quite different from the images others hold about us. Unfortunately, most of these images are more negative than they should be. Thus changing the way you think about yourself is the key to changing your self-image and your whole world.
is, make a list if you need to, but write down all of the great things you do every day. Don’t allow doubt s to occur in it.
flaw or weakness that you see about yourself. Well, roll up your sleeves and make a change of it as your primary task. If you think you’re silly because you aren’t good at math, find a tutor. If you think you’re weak because you can’t run a mile, get to the track and practice. If you think you’re dull because you don’t wear the latest trends, buy a few new clothes. But remember, just because you think it doesn’t mean it’s true.
to actively convince yourself of your positive qualities. Changing the way you think and working on those you need to improve will go a long way towards promoting a positive self-image. When you can pat(拍) yourself on the back, you’ll know you’re well on your way. Good luck! |
