我国发射了神舟四号宇宙飞船，为载人飞行进行了仿真人实验。飞船在轨道上正常飞行时处于“失重”状态，在这种环境中，以下哪个实验不能在地面一样正常进行;A．用刻度尺测长度;         B．用放大镜看物体;C．用平面镜改变光路;     D．用弹簧测力计测物重. 答案：DDo animals have a culture? What do we mean by “culture?” Lately social scientists have begun to ask if culture is found just in humans, or if some animals have a culture too. When we speak of culture, we mean a way of life a group of people have in common. Culture includes the beliefs and attitudes we learn. It is the patterns of behavior that help people to live together. It is also the patterns of behavior that make one group of people different from another group.Our culture lets us make up for having lost out strength, claws, long teeth, and other defenses. Instead we use tools, cooperate with one another, and communicate with language. But these aspects of human behavior, or “culture,” can also be found in the lives of certain animals. Animals can make tools, for example. We used to think that the ability to use tools was the dividing line between human beings and other animals. Lately, however, we have found that this is not the case. Chimpanzees(非洲小猩猩) can not only use tools but actually make tools themselves.Animals can also share knowledge with each other and use their own language to communicate. So it may be important for us to know that the line dividing us from animals is not as clear as we used to think.1.Choose the statement that best expresses the main idea.____.A.
