人类学家认为人类在地球上出现的标志是(  )

A.直立行走

B.产生语言

C.会使用天然工具

D.火的使用

答案

人类和现代类人猿的共同祖先是森林古猿.现代类人猿包括:大猩猩、黑猩猩、长臂猿和猩猩.在人类发展和进化中的重大事件有:直立行走--制造和使用工具--大脑进一步发达--语言的产生.直立行走是进化发展的基础,直立行走是人类脱离森林束缚,是使用工具制造工具的基础.恩格斯曾指出,直立行走是从猿到人转变过程中“具有决定意义的一步”.古猿的直立行走造成了前后肢的分工,直立行走使古人类能够将前肢解放出来,能使用工具.前肢所从事的活动越来越多,上肢更加灵巧.古猿慢慢的进化成了人类.因此,人类在地球上出现的主要标志是直立行走.
故选:A

    Have you ever heard of the saying, "If you want a friend, be one." 

    What does it mean? There are many different things that you can do to make friends. You may find out

what they are if you watch someone make friends. Here is how one new teacher made friends with the

students in her class on the first day of the school. When the bell rang, the teacher smiled at all the students.

Then she said, "Good morning. How nice it is to have all of you in my class this year! I want to know each

of you very much. I am sure we will enjoy working together." The teacher smiled, used a pleasant voice,

and acted in a friendly way. She told the students her name and wrote it on the blackboard. Then she told

them something she liked to do and hoped to do with them during the year. The students knew that she liked

many of the same things they liked. Everyone felt that she meant what she said. Each of them wanted to

know her better and be her friend. Then she let the students tell something about themselves. So they felt

that the teacher knew them. 

     Could you make friends as the teacher did? How do you know and like your classmates? One way is to

find out more about them. During the break you can talk to them. You may ask them their names and the

names of the schools they went to last year. They want to know about you, too. You may tell them about

your interests or your holiday experiences. It is often easy to be friends with people who have the same

interests and play the same games. As you talk, the others may be thinking, "I like to do the same things you

do. It should be fun to be friends with you." Remember! Just talking together in a friendly way is one good

way to make friends.
